    IN THE
    SUPREME COURT
    OF
    THE STATE OF ILLINOIS
    CONNIE MIKOLAJCZYK, Indiv. and as Special Adm’r of the Estate
    of James Mikolajczyk, Deceased, Appellee, v. FORD MOTOR
    COMPANY et al., Appellants.
    Opinion filed October 17, 2008.
    JUSTICE GARMAN delivered the judgment of the court, with
    opinion.
    Justices Freeman, Thomas, Karmeier, and Burke concurred in the
    judgment and opinion.
    Chief Justice Fitzgerald concurred in part and dissented in part,
    with opinion.
    Chief Justice Fitzgerald dissented upon denial of rehearing, with
    opinion.
    Justice Kilbride took no part in the decision.
    OPINION
    James Mikolajczyk died of injuries sustained when the Ford
    Escort he was driving was struck from behind by another vehicle. His
    widow, as special administrator of his estate, sued the other driver,
    claiming negligence, and Ford Motor Company and Mazda Motor
    Corporation, claiming defective design of the driver’s seat. Summary
    judgment was entered against the other driver. The claims against the
    other two defendants proceeded to a jury trial in the circuit court of
    Cook County. The jury found defendants liable and awarded plaintiff
    $2 million in damages for loss of money, goods, and services, and
    $25 million for loss of society.
    The appellate court affirmed in part and reversed in part.
    Mikolajczyk v. Ford Motor Co., 
    369 Ill. App. 3d 78
    (2006). This court
    denied defendants’ petition for leave to appeal, but remanded the
    matter to the appellate court with instructions to reconsider in light of
    Calles v. Scripto-Tokai Corp., 
    224 Ill. 2d 247
    (2007). On remand, the
    appellate court again affirmed in part and reversed in part, finding the
    damages awarded for loss of society to be excessive and remanding
    to the circuit court for a hearing on the proper amount of remittitur.
    
    374 Ill. App. 3d 646
    . This court granted defendants’ petition for leave
    to appeal pursuant to Supreme Court Rule 315 (
    210 Ill. 2d
    R. 315) to
    determine whether the trial court erred by instructing the jury on the
    consumer-expectation test and rejecting defendants’ tendered
    instruction on the risk-utility test for defective design. In addition, we
    allowed plaintiff’s petition to seek cross-relief on the damages issue.
    We have permitted the Products Liability Advisory Council, Inc.,
    the Illinois Manufacturers’ Association and the National Association
    of Manufacturers, the Illinois Association of Defense Trial Counsel,
    and the Alliance of Automobile Manufacturers, Inc., to file briefs
    amici curiae on behalf of the defendants. We have also permitted the
    Illinois Trial Lawyers Association to file a brief amicus curiae on
    behalf of the plaintiff. 
    210 Ill. 2d
    R. 345.
    BACKGROUND
    On February 4, 2000, William Timberlake shared two pints of gin
    with a friend before getting behind the wheel of his Cadillac. He was
    traveling approximately 60 miles per hour when he smashed into the
    rear of a 1996 Ford Escort that was stopped at a red light. The driver
    of the Escort, James Mikolajczyk, suffered severe, irreversible brain
    trauma and spent several days on life support before his death. His
    daughter, Elizabeth, then aged 10, who was asleep in the backseat at
    the time of the accident, suffered two broken legs. James was also
    survived by his wife, Connie, and son, Adam, then aged 14.
    -2-
    Plaintiff’s negligence suit against defendant Timberlake resulted
    in the entry of summary judgment. Plaintiff’s lawsuit against
    defendants Ford and Mazda alleged strict product liability premised
    on defective design of the driver’s seat of the Escort. Specifically, she
    claimed that as a result of the defective design of the seat, it collapsed
    when the car was struck from behind, causing James to be propelled
    rearward and to strike his head on the backseat of the car. Plaintiff
    further alleged that the design of the seat was unreasonably dangerous
    and that the design defect proximately caused James’s death. The
    Escort was manufactured by defendant Ford. The seat was designed
    by defendant Mazda; Ford had the authority to approve or disapprove
    the design.
    The trial testimony is summarized in detail in the appellate court
    
    opinion. 374 Ill. App. 3d at 650-53
    . For purposes of this appeal, it is
    necessary to note only that the evidence included testimony by expert
    witnesses for both parties regarding the risks and benefits posed by
    the “yielding” seat (referred to as the CT20 design), its compliance
    with federal safety requirements, the availability and feasibility of a
    rigid seat, the risks and benefits posed by the rigid seat design, and
    the seat designs employed in other makes and models of cars
    manufactured in 1996.
    The trial court instructed the jury using plaintiff’s tendered
    versions of Illinois Pattern Jury Instructions, Civil, Nos. 400.01.01
    (setting out the plaintiff’s claim of defective design and the
    defendants’ denials), 400.02 (setting out the plaintiff’s burden of
    proof and the elements of a claim for strict liability), and 400.06
    (defining the expression “unreasonably dangerous”). Illinois Pattern
    Jury Instructions, Civil, Nos. 400.01.01, 400.02, 400.06 (2006)
    (hereinafter IPI Civil (2006)). The trial court rejected defendants’
    tendered nonpattern jury instructions that would have specifically
    instructed the jury to consider the “overall safety” of the design,
    whether the foreseeable risks of harm of the design outweighed its
    benefits, and whether the adoption of a feasible alternative design
    would have avoided or reduced the risks. Defendants argued
    unsuccessfully that this instruction should be given either instead of
    or in addition to instruction 400.06.
    The jury answered the following special interrogatory in the
    affirmative: “Was the driver’s seat of the Mikolajczyk car in an
    -3-
    unreasonably dangerous condition that was a proximate cause of
    James Mikolajczyk’s death?” The jury then returned a verdict in favor
    of the plaintiff and awarded $2 million in damages for loss of money,
    goods, and services and $25 million for loss of society. The jury
    assigned 60% of fault to Timberlake and 40% to Ford and Mazda.
    The appellate court rejected defendants’ argument that the jury
    was improperly instructed, but reversed the judgment in part, finding
    the $25 million award for loss of society 
    excessive. 374 Ill. App. 3d at 674
    .
    Before this court, defendants argue that the appellate court
    “turned back the evolution of Illinois law” by applying the “outdated”
    consumer-expectation test rather than the risk-utility test that, they
    assert, is now the exclusive test for defective design of a complex
    product. In the alternative, they argue that even if this court has not
    expressly adopted risk-utility as the exclusive test in such cases, it
    should do so now. In effect, they argue that the trial court applied the
    wrong substantive law to plaintiff’s claim, raising this issue in the
    context of the trial court’s refusal to give their non-IPI jury
    instruction. Defendants also argue that a new trial must be granted in
    any event because the jury instructions that were given did not
    correspond to the evidence presented at trial.
    Plaintiff argues that the appellate court erred by finding the $25
    million award for loss of society excessive and remanding for a new
    hearing on defendants’ motion for remittitur.
    ANALYSIS
    Neither the first edition (1961) nor the second edition (1971) of
    the Illinois Pattern Jury Instructions, Civil, contained instructions
    dealing with claims of strict product liability. The 400.00 series of
    instructions, which deals with strict product liability, was adopted in
    1977 in a supplement to the second edition. See IPI Civil (2006), at
    xiii-xiv (foreward to the third edition). The third edition, which was
    adopted in 1992, retained instruction 400.06 without change, as have
    subsequent editions in 1995, 1997, 2000, and 2006. Pattern jury
    instruction 400.06 defines the term “unreasonably dangerous” in the
    context of a strict product liability claim:
    -4-
    “When I use the expression ‘unreasonably dangerous’ in
    these instructions, I mean unsafe when put to a use that is
    reasonably foreseeable considering the nature and function of
    the [product].” IPI Civil (2006) No. 400.06.
    The comment following this instruction observes that the
    “expression ‘unreasonably dangerous’ first found acceptance in
    Illinois in Suvada v. White Motor Co., 
    32 Ill. 2d 612
    , 
    210 N.E.2d 182
    (1965).”1 IPI Civil (2006) No. 400.06, Comment, at 562. In Suvada,
    this court recognized a cause of action for strict liability in tort against
    the manufacturer of a product whose defective condition made it
    unreasonably dangerous to the user or consumer. This court noted that
    its conclusion “coincide[d] with the position taken in section 402A of
    the American Law Institute’s revised Restatement of the Law of
    Torts,” which had recently been approved. 
    Suvada, 32 Ill. 2d at 621
    .
    This section provides, in part, that:
    “One who sells any product in a defective condition
    unreasonably dangerous to the user or consumer or to his
    property is subject to liability for physical harm thereby
    caused to the ultimate user or consumer, or to his property
    ***.” Restatement (Second) of Torts §402A (1965).
    The drafters of the pattern jury instruction explained that they
    chose the phrase “unreasonably dangerous condition” instead of the
    words “defect” or “defective condition” because the phrase “is more
    conversational and is less likely to suggest traditional concepts of
    fault to the jurors.” The drafters noted, further, that an instruction
    defining “unreasonably dangerous” is needed “because the concept is
    not generally understood by, nor within the common experience of,
    jurors.” Under this instruction, “a product can be ‘unreasonably
    dangerous’ only when put to a use that is reasonably foreseeable.” IPI
    Civil (2006) No. 400.06, Comment, at 563.
    It has since been well established that to recover in a strict product
    liability action, a plaintiff must plead and prove that the injury
    1
    Suvada was impliedly overruled on other grounds in Frazer v. A.F.
    Munsterman, Inc., 
    123 Ill. 2d 245
    (1988). The implied overruling of Suvada
    was recognized by this court in Dixon v. Chicago & North Western
    Transportation Co., 
    151 Ill. 2d 108
    , 123 (1992).
    -5-
    complained of resulted from a condition of the product, that the
    condition was unreasonably dangerous, and that it existed at the time
    the product left the manufacturer’s control. Sollami v. Eaton, 
    201 Ill. 2d
    1, 7 (2002). A product may be found to be unreasonably dangerous
    based on proof of any one of three conditions: a physical defect in the
    product itself, a defect in the product’s design, or a failure of the
    manufacturer to warn of the danger or to instruct on the proper use of
    the product. Sollami, 
    201 Ill. 2d
    at 7.
    As early as 1979, this court held that when a strict liability claim
    is based on an alleged design defect, the product may be proven to be
    unreasonably dangerous “by evidence of the availability and
    feasibility of alternate designs at the time of its manufacture, or that
    the design used did not conform with the design standards of the
    industry, design guidelines provided by an authoritative voluntary
    association, or design criteria set by legislation or governmental
    regulation.” Anderson v. Hyster Co., 
    74 Ill. 2d 364
    , 368 (1979).
    That same year, this court held that a product may be found
    unreasonably dangerous based on a design defect if the plaintiff
    presents evidence of an alternative design that is “economical,
    practical and effective.” Kerns v. Engelke, 
    76 Ill. 2d 154
    , 162-63
    (1979). Such evidence introduces the question of feasibility, “ ‘since
    a manufacturer’s product can hardly be faulted if safer alternatives are
    not feasible.’ ” 
    Kerns, 76 Ill. 2d at 163
    , quoting Sutkowski v.
    Universal Marion Corp., 
    5 Ill. App. 3d 313
    , 319 (1972). Because the
    evidence and the court’s instructions were sufficient for the jury to
    find for the plaintiff in Kerns, this court did not determine whether a
    plaintiff claiming design defect must plead and prove that a feasible
    alternative design is available. 
    Kerns, 76 Ill. 2d at 163
    -64.
    In Lamkin v. Towner, 
    138 Ill. 2d 510
    , 528 (1990), this court
    reiterated its earlier adoption of section 402A of the Restatement
    (Second) of Torts, observing that a product is “unreasonably
    dangerous” due to a defect in either manufacturing or design when it
    is “ ‘dangerous to an extent beyond that which would be
    contemplated by the ordinary consumer who purchases it, with the
    ordinary knowledge common to the community as to its
    characteristics.’ ” 
    Lamkin, 138 Ill. 2d at 528
    , quoting Restatement
    (Second) of Torts §402A, Comment i, at 352 (1965).
    -6-
    We further stated that in a strict product liability action, a claim
    of defective design may be proven in either of two ways. First, the
    plaintiff may introduce “evidence that the product failed to perform
    as safely as an ordinary consumer would expect when used in an
    intended or reasonably foreseeable manner.” 
    Lamkin, 138 Ill. 2d at 529
    . This has come to be known as the consumer-expectation test.
    Second, the plaintiff may introduce “evidence that the product’s
    design proximately caused his injury.” If the defendant thereafter
    “fails to prove that on balance the benefits of the challenged design
    outweigh the risk of danger inherent in such designs,” the plaintiff
    will prevail. 
    Lamkin, 138 Ill. 2d at 529
    . This test, which added the
    balancing of risks and benefits to the alternative design and feasibility
    inquiries adopted in Anderson and Kerns, has come to be known as
    the risk-utility or risk-benefit test.
    The product at issue in Lamkin was a window screen. The
    plaintiffs were parents of two children who were injured when they
    fell from apartment windows. The trial court denied the defendants’
    motions for summary judgment and certified four questions for
    interlocutory appeal. 
    Lamkin, 138 Ill. 2d at 516-17
    . On the question
    of the plaintiffs’ claims of strict liability for defective design, this
    court applied both the consumer-expectation test and the risk-utility
    test to the evidentiary materials in the record and determined that the
    trial court’s denial of the motion for summary judgment was improper
    because plaintiffs could not have met either test. 
    Lamkin, 138 Ill. 2d at 529
    -31.
    Specifically, under the consumer-expectation test, the question
    was whether “the window screens failed to perform as safely as an
    ordinary consumer would expect when used in an intended or
    reasonably foreseeable manner.” (Emphasis in original.) 
    Lamkin, 138 Ill. 2d at 529
    . Because window screens are designed for ventilation
    and to prevent insects from entering, not to prevent an individual
    from falling, the window screen did what it was designed to do
    without unreasonable danger. The danger arose only when the
    window screen did not do something it was not designed to do. The
    ordinary person, with ordinary knowledge, would appreciate this
    distinction. 
    Lamkin, 138 Ill. 2d at 529
    -30.
    Applying the risk-utility test, this court considered whether there
    was evidence of how the “window screens’ design proximately
    -7-
    caused” the children’s injuries. (Emphasis in original.) 
    Lamkin, 138 Ill. 2d at 530
    . This court asked whether the plaintiff had provided
    “evidence of how the window screens’ design could have been altered
    to create a safer screen *** or any evidence of the form and feasibility
    of the alternative screen design.” 
    Lamkin, 138 Ill. 2d at 530
    . Finding
    no evidence to support the plaintiffs’ allegations, this court found, as
    a matter of law, that the window screens were not “ ‘defective or
    unreasonably dangerous’ such as to serve as the basis for a products
    liability action.” 
    Lamkin, 138 Ill. 2d at 530
    -31.
    Notably, in Lamkin, when applying the consumer-expectation test,
    this court focused on the manner in which the allegedly dangerous
    product was being used. When applying the risk-utility test, this court
    focused on the availability and feasibility of alternative designs for
    the product. IPI Civil (2006) No. 400.06, which was given in the
    present case, also focuses on the use to which the allegedly defective
    product was being put, thus stating, at least in part, the content of the
    consumer-expectation test. The instruction, however, does not include
    any content specific to the risk-utility test.
    (1)
    Defendants argue that this court’s decisions subsequent to
    Lamkin, specifically Hansen v. Baxter Healthcare Corp., 
    198 Ill. 2d 420
    (2002), Blue v. Environmental Engineering, Inc., 
    215 Ill. 2d 78
    (2005), and Calles, 
    224 Ill. 2d 247
    , have established that in a product
    liability action predicated on a claim of defective design, the risk-
    utility test is the only proper test. If this court’s precedents do not
    establish this definitive rule, they argue, our decisions have
    nevertheless established that the risk-utility test is the only test to be
    applied if the product at issue is complex and if the injury occurred
    in circumstances unfamiliar to the average consumer. Thus,
    defendants argue, even if the consumer-expectation test might still be
    applicable in some design defect cases, it is “reserved” for cases
    involving simple products or everyday circumstances. They argue,
    further, that despite this development in the law of strict product
    liability, the existing pattern jury instruction misinforms the jury by
    not setting out the applicable test.
    -8-
    The defendants frame the question for this court as whether the
    existing jury instruction accurately states the law, subject to de novo
    review, citing People v. Parker, 
    223 Ill. 2d 494
    , 501 (2006). Plaintiff
    argues for application of the abuse of discretion standard, under
    which reversal is not appropriate for giving a faulty instruction or
    refusing to give a tendered instruction absent a showing of prejudice
    to party’s right to a fair trial. McCarthy v. Kunicki, 
    355 Ill. App. 3d 957
    , 970 (2005). Defendants reply that even if this court were to
    apply the abuse of discretion standard, it was an abuse of discretion
    requiring a new trial for the trial court to give an outdated,
    inapplicable instruction on a key issue, citing Eshoo v. Chicago
    Transit Authority, 
    309 Ill. App. 3d 831
    , 836-37 (1999). We agree
    with defendants that the question presented at this stage of our
    analysis is a question of law because it asks whether, as a matter of
    substantive law, this court has abandoned or limited the application
    of the consumer-expectation test in design defect cases and replaced
    it with the risk-utility test. Our review is, therefore, de novo.
    We first used the expression “risk-utility” in 
    Hansen, 198 Ill. 2d at 428
    , where the unintentional disconnection of an intravenous
    catheter connecting device had caused a fatal air embolism. The
    plaintiff claimed that the manufacturer failed to warn users of the
    device of the likelihood of unintentional disconnection and also that
    the device was unreasonably dangerous due to a design defect.
    
    Hansen, 198 Ill. 2d at 423-24
    . The jury rendered a general verdict,
    finding the defendant liable. The appellate court found that the
    general verdict could not be sustained on the failure-to-warn theory,
    but that the evidence justified a finding of design defect under either
    the consumer-expectation test or the risk-utility test. Hansen v. Baxter
    Healthcare Corp., 
    309 Ill. App. 3d 869
    (1999). The defendant
    manufacturer argued on appeal to this court that the appellate court
    erred by applying risk-utility analysis. 
    Hansen, 198 Ill. 2d at 428
    . The
    defendant argued for application of only the consumer-expectation
    test, but claimed that the relevant expectations were those of health-
    care professionals, not patients, and that the ordinary professional
    consumer of this product would not have found it more dangerous
    than expected. 
    Hansen, 198 Ill. 2d at 433-34
    .
    This court first addressed the failure to warn claim and found,
    contrary to the appellate court’s holding, that the defendant had a duty
    -9-
    to warn physicians and other health-care professionals who might use
    the device of its “known dangerous propensities” and that the jury’s
    general verdict could reasonably have been based on a finding that the
    defendant had not fulfilled that duty. 
    Hansen, 198 Ill. 2d at 430-32
    .
    This court then turned to the design defect claim. We must note,
    however, that this court’s holding on the failure to warn claim would
    have been a sufficient basis to affirm the trial court judgment.
    Arguably, it was not necessary for this court to reach the design defect
    claim, even though the defendant’s petition for leave to appeal had
    been granted to review the appellate court’s ruling on this issue.
    Whether this renders the remainder of the decision dictum is open to
    debate, but if dictum, it is judicial dictum. Hawes v. Luhr Brothers,
    Inc., 
    212 Ill. 2d 93
    , 100 (2004) (supreme court’s unnecessary
    pronouncement on an issue briefed and argued by the parties is
    “judicial dicta,” rather than mere “obiter dicta” and should be given
    dispositive weight by the lower courts).
    Considering the consumer-expectation test, this court concluded
    that the ordinary-consumer-expectation test, rather than the ordinary-
    physician-expectation test, applied to the design defect claim because
    the patient “was the person who would be harmed if the device
    failed” and because she “could have reasonably expected that her IV
    catheter connection, if properly designed and manufactured, would be
    safe to use for its intended purpose.” 
    Hansen, 198 Ill. 2d at 435
    . The
    evidence at trial was sufficient to establish that the design of the
    device was defective under this test. Thus, the appellate court was
    correct that the jury’s decision was not against the manifest weight of
    the evidence. 
    Hansen, 198 Ill. 2d at 435
    . Again, our analysis could
    have stopped here, but we went on to consider whether the evidence
    supported the verdict under the risk-utility test.
    The defendant in Hansen argued that the risk-utility test was not
    appropriately applied to the medical device because it was simple and
    its risks were well known to the medical community. Hansen, 
    198 Ill. 2d
    at 436. The defendant relied on Scoby v. Vulcan-Hart Corp., 
    211 Ill. App. 3d 106
    (1991), in which the appellate court had rejected
    application of the risk-utility test to a claim that a deep-fat fryer used
    in a restaurant was defectively designed because it lacked a cover,
    stating:
    -10-
    “Somewhere, a line must be drawn beyond which the danger-
    utility test cannot be applied. Considering not only the
    obvious nature of any danger here but, also, the simple nature
    of the mechanism involved, we conclude that the circuit court
    properly applied only the consumer-user contemplation test.”
    
    Scoby, 211 Ill. App. 3d at 112
    .
    This court neither rejected nor adopted the principle set out in
    Scoby, but found that even if such a principle applied, it would not
    have affected the outcome in Hansen. First, such a conclusion was
    “not compelled by the facts” related to the medical device, which,
    unlike the deep-fat fryer, had been developed and marketed as a
    safety device. Second, this court found that, unlike the deep-fat fryer,
    the danger presented by the medical device was “not obvious, nor was
    the mechanism simple.” Hansen, 
    198 Ill. 2d
    at 437. Thus, this court
    concluded that evidence of the existence of an alternative, safer
    design for the medical device was properly admitted and that the
    record was “sufficient to sustain a finding of unreasonable
    dangerousness under a risk-utility analysis.” Hansen, 
    198 Ill. 2d
    at
    436.
    We also declined the defendant’s invitation to adopt a new test for
    design defects in medical devices and prescription drugs under
    section 6 of the then-new Restatement (Third) of Torts: Products
    Liability (1998) (hereinafter Products Liability Restatement), finding
    the argument forfeited. We did, however, leave open the possibility
    of considering the adoption of sections of the Products Liability
    Restatement in the proper case. Hansen, 
    198 Ill. 2d
    at 438.
    No issue was raised in Hansen regarding jury instructions. Both
    tests were applied by this court in the context of determining whether
    the evidence in the record supported the jury’s general verdict.
    Thus, by 2002, our case law had established that strict liability
    may be imposed based on proof of injury proximately caused by an
    unreasonably dangerous condition of a product and that such a
    condition may consist of a manufacturing defect, a design defect, or
    inadequate warnings. We had further established that a product’s
    design may be found to be unreasonably dangerous and, thus,
    defective under either the consumer-expectation test or the risk-utility
    test. 
    Lamkin, 138 Ill. 2d at 528
    -29. We had not limited the application
    of either test to a specific class of products. We had concluded that a
    -11-
    “complex” product, such as a medical device, may be subjected to
    both tests, but we did not define “complex” except to distinguish an
    IV catheter connector from a deep-fat fryer. Hansen, 
    198 Ill. 2d
    at
    437. The pattern jury instruction defining “unreasonably dangerous,”
    which had been adopted in 1977, many years prior to our decisions in
    Lamkin and Hansen, remained unchanged despite our adoption of two
    alternative methods of proving that a product is defectively designed
    because it presents an unreasonable danger.
    We next considered the risk-utility test in 2005 in Blue. The
    product at issue was a trash compactor. The plaintiff pleaded both
    negligence and strict product liability based on design defect, but was
    forced to proceed solely on the negligence theory after the strict
    liability count was dismissed because it was filed beyond the limits
    of the statute of repose. 
    Blue, 215 Ill. 2d at 81
    . The issue presented to
    this court was whether the trial court erred by giving the jury a special
    interrogatory, over plaintiff’s objection, asking whether “the risk of
    injury by sticking a foot over or through a gate into a moving
    compactor [was] open and obvious.” See 
    Blue, 215 Ill. 2d at 85
    . The
    jury answered this question in the affirmative, but nevertheless
    returned a general verdict for the plaintiff. The trial court granted the
    defendants’ posttrial motion for judgment n.o.v. on the basis that the
    jury’s answer to the special interrogatory was inconsistent with the
    general verdict.
    The appellate court reversed, noting that in a negligence action
    based on breach of a duty to warn, no such duty exists when the
    danger is open and obvious. 
    Blue, 215 Ill. 2d at 86
    . The appellate
    court also held, however, that an open and obvious risk is not an
    absolute bar to liability in an action for negligent design, citing
    Wortel v. Somerset Industries, Inc., 
    331 Ill. App. 3d 895
    , 902-03
    (2002) (open and obvious danger does not necessarily bar recovery in
    a strict product liability case based on defective design; under the
    risk-utility test, the open and obvious nature of the risk posed by the
    product is merely a factor to be considered in the overall assessment
    of its risks and utility). Blue v. Environmental Engineering, Inc., 
    345 Ill. App. 3d 455
    , 468 (2003).
    After a discussion of the risk-utility test and its similarity to the
    negligence standard, a plurality of this court concluded that the risk-
    utility test, which would have been applicable to the dismissed strict
    -12-
    liability claims, did not apply to the claim of negligent design. 
    Blue, 215 Ill. 2d at 97-98
    .
    Defendant argues that in Blue, this court embraced section 2 of
    the Products Liability Restatement, which states:
    “A product is defective when, at the time of sale or
    distribution, it contains a manufacturing defect, is defective
    in design, or is defective because of inadequate instructions or
    warnings. A product:
    (a) contains a manufacturing defect when the product
    departs from its intended design even though all possible
    care was exercised in the preparation and marketing of the
    product:
    (b) is defective in design when the foreseeable risks of
    harm posed by the product could have been reduced or
    avoided by the adoption of a reasonable alternative design
    by the seller or other distributor, or a predecessor in the
    commercial chain of distribution, and the omission of the
    alternative design renders the product not reasonably safe;
    (c) is defective because of inadequate instructions or
    warnings when the foreseeable risks of harm posed by the
    product could have been reduced or avoided by the
    provision of reasonable instructions or warnings by the
    seller or other distributor, or a predecessor in the
    commercial chain of distribution, and the omission of the
    instructions or warnings renders the product not
    reasonably safe.” Restatement (Third) of Torts: Products
    Liability §2, at 14 (1998).
    The first sentence of this section parallels this court’s language in
    Lamkin, recognizing three separate bases for strict product liability.
    Paragraph (a) sets out a test for defective manufacturing; paragraph
    (b) applies the risk-utility test to claims of defective design; and
    paragraph (c) sets out a test for inadequate instructions or warnings.
    Our “adoption” of this section of the Products Liability Restatement,
    according to defendants, means that use of the consumer-expectation
    test is now “restricted”to claims of manufacturing defect and that the
    risk-utility test alone applies to all claims of defective design.
    -13-
    Defendants argue further that even though Blue was a negligence
    case, not a strict liability case, the appellate court in the present case
    erred by treating our discussion of section 2 as mere dicta. Even
    though Blue was a plurality opinion, defendants assert that none of
    the concurring justices questioned whether the risk-utility test governs
    strict liability design defect cases and that two concurring justices
    suggested expanding the risk-utility test to cover negligent design
    claims as well. 
    Blue, 215 Ill. 2d at 119
    (Fitzgerald, J., specially
    concurring, joined by McMorrow, C.J.). They argue further that a
    “fair reading” of Blue suggests that it was “a signpost along the way
    to the law’s current place, the risk-utility test.”
    We disagree. We did cite section 2 of the Products Liability
    Restatement in Blue, but only in the context of distinguishing
    negligent design claims from strict product liability defective design
    claims. 
    Blue, 215 Ill. 2d at 93-94
    . We noted that this section was
    drafted in response to the recognized “inadequacy of section 402A to
    address claims of defective design and defects based on inadequate
    instructions and warnings.” 
    Blue, 215 Ill. 2d at 93
    . We did not,
    however, expressly or impliedly adopt section 2(b) as the sole,
    exclusive test for dangerousness in strict liability design defect cases.
    The most that can be said regarding Blue is that a plurality of this
    court noted the American Law Institute’s observation that “the same
    rationale for imposing strict liability in manufacturing defect cases
    does not apply to design defects.” 
    Blue, 215 Ill. 2d at 94
    , citing
    Restatement (Third) of Torts: Products Liability §2, Comment a, at
    16 (1998).
    The Blue plurality went on to consider whether, under the risk-
    utility test, once the plaintiff shows that a design defect proximately
    caused his injury, the burden of proof shifts to the defendant to prove
    that the benefits of the design outweigh its inherent danger. 
    Blue, 215 Ill. 2d at 98-99
    . This burden-shifting formulation of the risk-utility
    test comes from Lamkin (138 Ill. 2d at 529), but was not a part of the
    holding in that case. In fact, the holding in Lamkin negates any such
    burden on the defendant, because this court found that summary
    judgment for the defendant in that case was proper. If the burden had
    shifted to the defendant, summary judgment could not have been
    entered in the defendant’s favor. 
    Blue, 215 Ill. 2d at 99
    .
    -14-
    The burden-shifting formulation emanates from a citation to
    Barker v. Lull Engineering Co., 
    20 Cal. 3d 413
    , 429-30, 
    573 P.2d 443
    , 453-54, 
    143 Cal. Rptr. 225
    , 235-36 (1978), widely recognized
    as the seminal case on risk-utility. This court cited Barker in Palmer
    v. Avco Distributing Corp., 
    82 Ill. 2d 211
    , 219-20 (1980), and then
    cited both Palmer and Barker in Lamkin (138 Ill. 2d at 529), but no
    decision of this court has expressly adopted this burden-shifting
    formulation of the risk-utility test.
    Having already concluded that the risk-utility test did not apply to
    the plaintiff’s negligent design claim, it was not necessary for us to
    reach this question in Blue. We addressed it “only because of the
    appellate court’s finding that the risk-utility test applied” to the
    negligence claim in that case. 
    Blue, 215 Ill. 2d at 98
    . The plurality
    cited, with approval, a comment to section 2 of the Products Liability
    Restatement, which states that a plaintiff must establish a prima facie
    case of design defect by introducing evidence of a technologically
    feasible and practical alternative design that would have reduced or
    prevented the harm. Restatement (Third) of Torts: Products Liability
    §2, Comment f, at 23-24 (1998). Once that showing is made, the issue
    of liability is “one for the trier of fact to resolve.” 
    Blue, 215 Ill. 2d at 100
    .
    With respect to the issues in the present case, the plurality opinion
    in Blue did not abandon or limit use of the consumer-expectation test.
    Blue signals only that this court is aware of the potential
    shortcomings of using the consumer-expectation test in design defect
    cases. The plurality in Blue also rejected a burden-shifting element of
    the risk-utility test, a conclusion that none of the concurring justices
    questioned.
    Ultimately, defendants rely on this court’s decision in Calles to
    argue that risk-utility is now the sole, exclusive test to determine
    whether an allegedly defectively designed product is unreasonably
    dangerous.
    The product at issue in Calles was a utility lighter. The plaintiff
    was the mother of a three-year-old who died of smoke inhalation after
    her twin sister started a fire with the lighter. The plaintiff made both
    negligence and strict liability claims. 
    Calles, 224 Ill. 2d at 251
    . The
    trial court granted summary judgment for the defendants.
    -15-
    The appellate court noted the Blue plurality’s citation to Scoby “as
    authority that some simple products present such obvious dangers that
    the court need not apply the risk-utility balancing test.” Calles v.
    Scripto-Tokai Corp., 
    358 Ill. App. 3d 975
    , 982 (2005). Under this
    reasoning, the appellate court concluded, if a product is simple and its
    danger obvious, summary judgment for the defendant manufacturer
    is warranted if “the balance of all considerations so clearly favors the
    defendant that no reasonable jury could find for the plaintiff.” 
    Calles, 358 Ill. App. 3d at 983
    . Reversing in part, the appellate court held that
    the lighter did “not qualify as the kind of especially simple device for
    which the result of the risk-utility balancing is too obvious for trial.”
    
    Calles, 358 Ill. App. 3d at 983
    .
    The issue presented to this court in Calles was whether we had
    established, in Blue, a “simple product exception” to application of
    the risk-utility test in strict liability defective design cases.
    Specifically, the question was formulated as whether a product that
    is deemed “simple,” with open and obvious dangers, was per se
    exempt from the risk-utility test. 
    Calles, 224 Ill. 2d at 250
    .
    We noted, again, that the consumer-expectation test was
    developed in the context of claims of manufacturing defects, but that
    it came to be applied to design defect claims as well. Calles, 
    224 Ill. 2d
    at 254-55. We acknowledged that the applicability of the
    consumer-expectation test to alleged design defects had been
    questioned and that the risk-utility test had been devised to respond
    to these concerns. Calles, 
    224 Ill. 2d
    at 255. We did not, however,
    state that the consumer-expectation test no longer applies in design
    defect cases. Indeed, we applied both tests in our analysis of the
    utility lighter after observing that “[s]ince Lamkin, this court has
    continued to employ these two tests when determining whether a
    product is unreasonably dangerous.” Calles, 
    224 Ill. 2d
    at 256.
    We observed that while a product might satisfy ordinary
    consumer expectations, its design could still be found defective using
    risk-utility analysis. Calles, 
    224 Ill. 2d
    at 256. Thus, the plaintiff in
    a design defect case whose claim failed the consumer-expectation test
    could nevertheless prevail under the risk-utility test.
    The utility lighter at issue in Calles met the expectations of the
    ordinary adult consumer because it produced a flame when used as
    intended. The lighter, however, had not been used in its intended
    -16-
    manner; it had been used by a three-year-old child to start a fatal fire.
    This use, while tragic, was reasonably foreseeable. Because the
    lighter produced a flame when used in a reasonably foreseeable
    manner, thus fulfilling the expectations of the ordinary consumer, it
    could not, as a matter of law, be found unreasonably dangerous under
    the consumer-expectation test. Calles, 
    224 Ill. 2d
    at 258-59.
    We then turned to the risk-utility analysis because it might still
    have been possible for the plaintiff to prevail under that test. Our first
    step was to address the defendant’s reliance on Scoby for the
    proposition that there is a “simple product” exception to the risk-
    utility test that applies when the mechanism is so simple and the
    danger so obvious that it is proper to apply only the consumer-
    expectation test, citing 
    Scoby, 211 Ill. App. 3d at 112
    . The defendant
    argued that the utility lighter, like the deep-fat fryer at issue in Scoby,
    was such a product and that, therefore, the risk-utility test should not
    be utilized.
    We examined Scoby and concluded that the exception to risk-
    utility analysis that it espoused contained two separate components:
    the product must be “simple” and its danger must be “open and
    obvious.” We disagreed with this formulation, finding that “the
    dangers associated with a product that is deemed ‘simple’ are, by
    their very nature, open and obvious.” Calles, 
    224 Ill. 2d
    at 261. This
    is certainly true of the danger of being burned by boiling oil in a deep-
    fat fryer or the danger of starting a fire with a utility lighter. Thus, we
    concluded, the purported simple-product exception is “nothing more
    than the adoption of a general rule that a manufacturer will not be
    liable for open and obvious dangers.” Calles, 
    224 Ill. 2d
    at 261.
    After further analysis, we rejected such a per se rule exempting
    products with open and obvious dangers from risk-utility analysis.
    Instead, we concluded, the open and obvious danger of a product is
    but one factor to be considered when applying the risk-utility test.
    Calles, 
    224 Ill. 2d
    at 262. Our application of the risk-utility test to the
    evidence of record resulted in our conclusion that there was a
    disputed issue of material fact that precluded the entry of summary
    judgment in the defendant’s favor. Calles, 
    224 Ill. 2d
    at 268-69.
    In the end, Calles rejected the premise that in a certain category
    of strict liability cases, only the consumer-expectation test applies.
    Calles, 
    224 Ill. 2d
    at 263. Defendants argue that as a result, Calles has
    -17-
    rendered the consumer-expectation test “largely superfluous,”
    because “the law is now clear: the risk-utility test applies to the
    design of all products, even simple products with open and obvious
    dangers.” Defendants base this argument primarily on our citation in
    Calles to the decision of the Supreme Court of California in Soule v.
    General Motors Corp., 
    8 Cal. 4th 548
    , 
    882 P.2d 298
    , 
    34 Cal. Rptr. 2d 607
    (1994). Calles, 
    224 Ill. 2d
    at 256.
    We had previously cited Barker, another California case, in
    Lamkin for the rationale for employing both the consumer-
    expectation test and the risk-utility test. 
    Lamkin, 138 Ill. 2d at 529
    ,
    citing Parker v. Avco Distributing Corp., 
    82 Ill. 2d 211
    , 219-20
    (1980), citing 
    Barker, 20 Cal. 3d at 427-28
    , 573 P.2d at 452, 143 Cal.
    Rptr. at 234-35. We reiterated that rationale, and our citation to
    Barker, in Calles. Calles, 
    224 Ill. 2d
    at 255-56. Following a brief
    explanation of the rationale of Barker, we directed the reader to “see
    also” Soule, which, we explained in a parenthetical remark, refined
    the Barker risk-utility test and held that the “ ‘consumer expectations
    test is reserved for cases in which the everyday experience of the
    product’s users permits a conclusion that the product’s design
    violated minimum safety assumptions,’ ” but that “ ‘the risks and
    benefits of a challenged design must be carefully balanced whenever
    the issue of design defect goes beyond the common experience of the
    product’s users.’ ” (Emphases omitted.) Calles, 
    224 Ill. 2d
    at 256,
    quoting 
    Soule, 8 Cal. 4th at 567
    , 882 P.2d at 
    308, 34 Cal. Rptr. 2d at 617
    . We reject this argument. Our mere citation of Soule, using the
    signal “see also,” and without further discussion, cannot be read as
    this court’s adoption of a new rule that would necessarily overrule
    Lamkin and its progeny.
    Calles concluded that a product that presents an open and obvious
    danger is not per se exempt from application of the risk-utility test in
    a strict liability case. Calles, however, did not address the issue raised
    by defendants in the present case–whether a complex product is per
    se exempt from the consumer-expectation test.
    Nothing in our past decisions, even where we have applied the
    risk-utility test, has signaled a rejection of the consumer-expectation
    test merely because a complex product was involved. For example,
    in Hansen, which involved a complex product (Hansen, 
    198 Ill. 2d
    at
    437 (intravenous catheter connecting device is not simple)), we found
    -18-
    that the evidence at trial was sufficient to sustain a finding of
    defective design under both tests. 
    Hansen, 198 Ill. 2d at 435
    (consumer-expectation), 437-38 (risk-utility). We, therefore, reject
    defendants’ claim that under Illinois law the risk-utility test is the sole
    measure of the dangerousness of an allegedly defectively designed
    product in all strict liability cases or in a subset of those cases.
    (2)
    Defendants argue that if we have not adopted the risk-utility test
    as the sole, exclusive test in design defect cases, we should do so
    now. They argue, in the alternative, that if we do not adopt the risk-
    utility test as the sole, exclusive test in all design defect cases, it
    should be the sole, exclusive test when the product is complex and
    the circumstances are not familiar to the ordinary consumer. This
    case, they insist, illustrates the need to restrict application of the
    consumer-expectation test to claims of defective manufacture or, at
    least, to design defects in simple products.
    According to defendants, the consumer-expectation test evolved
    to evaluate claims of manufacturing defect where it is reasonable to
    believe that jurors, as ordinary consumers, can rely on their own
    experience and expectations to determine whether a manufacturing
    defect has rendered a product unreasonably dangerous. This,
    defendants assert, is a simple, straight-forward inquiry focused on one
    particular “unit” of the product and not on the product as a whole.
    Thus, there are no countervailing benefits to consider when a
    manufacturing defect is alleged.
    The consumer-expectation test, defendants argue, does not make
    sense when a design defect is alleged because design decisions, by
    their very nature, involve considerations of the feasibility of
    alternative designs, cost, safety, and other factors with which the
    ordinary consumer is not familiar. In the context of the present case,
    defendants assert, the jurors could not have had reasonable
    expectations of their own regarding the proper degree of rigidity or
    flexibility in a car seat or how a seat should function in a wide range
    of potential accident conditions. According to defendants, the risk-
    utility test is specifically fashioned to evaluate this kind of claim and
    -19-
    should be the sole measure of whether the product is unreasonably
    dangerous due to a design defect.
    Plaintiff responds that defendants are proposing a “radical
    theory,” adoption of which would overrule Lamkin, Hansen, and
    Calles. Even if the proposed new rule were limited to cases involving
    complex products, plaintiffs claim, the distinction between simple
    and complex products is unworkable because there is no rational
    basis on which to distinguish them. Indeed, plaintiff points out, this
    court was divided in Calles on the question of whether the utility
    lighter was a “simple” product. See Calles, 
    224 Ill. 2d
    at 274
    (Karmeier, J., specially concurring).
    The rule advocated by defendants is contained in section 2(b) of
    the Products Liability Restatement, which would allow a finding of
    design defect only “when the foreseeable risks of harm posed by the
    product could have been reduced or avoided by the adoption of a
    reasonable alternative design *** and the omission of the alternative
    design renders the product not reasonably safe.” Restatement (Third)
    of Torts: Products Liability §2(b), at 14 (1998).
    If we were to accept defendants’ invitation to adopt section 2(b)
    of the Products Liability Restatement, we would indeed overrule
    precedent, because section 2(b) would redefine the elements of a
    product liability claim based on alleged defective design.
    Under Illinois law, the elements of a claim of strict liability based
    on a defect in the product are: (1) a condition of the product as a
    result of manufacturing or design, (2) that made the product
    unreasonably dangerous, (3) and that existed at the time the product
    left the defendant’s control, and (4) an injury to the plaintiff, (5) that
    was proximately caused by the condition. The plaintiff has the burden
    of proof on each element. See Sollami, 
    201 Ill. 2d
    at 7; Suvada, 
    32 Ill. 2d
    at 623.
    Section 2(b) of the Products Liability Restatement would alter the
    “unreasonably dangerous” element in design defect cases in two
    significant ways. First, a plaintiff would be required to plead and
    prove the existence of a feasible alternative design in every case.
    Second, instead of proving that the defect rendered the product
    “unreasonably dangerous,” the plaintiff would have the burden of
    proving that the product was “not reasonably safe.”
    -20-
    The first of these new elements was briefly a part of Illinois law.
    In 1995, enactment of Public Act 89–7, the so-called “Tort Reform
    Act,” added section 2–2104 to the Code of Civil Procedure. This
    section provided that in strict product liability actions, the design of
    a product is “presumed to be reasonably safe,” unless the plaintiff
    proves that, “at the time the product left the control of the
    manufacturer, a practical and technically feasible alternative design
    was available that would have prevented the harm without
    significantly impairing the usefulness, desirability, or marketability
    of the product.” 735 ILCS 5/2–2104 (West 1996) (declared
    unconstitutional).
    In 1997, this court decided Best v. Taylor Machine Works, 
    179 Ill. 2d
    367, 467 (1997), which held Public Act 89–7 unconstitutional in
    its entirety. Section 2–2104, standing alone, was not found
    unconstitutional, but this court held in Best that provisions of the act
    that were essential to the legislative purpose could not be severed
    from the rest of the act.
    Our legislature has not reenacted this provision in the decade
    since Best was decided. We are reluctant to make a change that would
    so fundamentally alter the law of product liability in this state based
    solely on the suggestion that the drafters of the Restatement have a
    better idea of what the law should be than our own legislature. Such
    a change, if it is to be made, is a matter of public policy, better suited
    to legislative action than judicial decisionmaking.
    As for the second alteration, adoption of section 2(b) of the
    Products Liability Restatement would require the plaintiff to prove
    that the alleged defect renders the product “not reasonably safe”
    rather than “unreasonably dangerous.” This change has its roots in a
    law review article that argued:
    “[T]he term ‘unreasonably dangerous’ gives rise to the
    impression that the plaintiff must prove that the product was
    ‘unusually or extremely dangerous.’ The term ‘not reasonably
    safe’ is less subject to misinterpretation.” Restatement (Third)
    of Torts: Products Liability §2, Reporters’ Note, at 80 (1978),
    citing J. Wade, Strict Tort Liability of Manufacturers, 19 Sw.
    L.J. 5, 15 (1965), and J. Wade, On the Nature of Strict Tort
    Liability for Products, 44 Miss. L.J. 825, 833 (1973).
    -21-
    The term “not reasonably safe” offers an “aspirational advantage,”
    because it “elevates the norm” to one of reasonable safety, and
    “serves symbolically to provide a signal that (reasonable) product
    safety–as a positive goal required by the law–must now be afforded
    a central place in the decisional calculus of manufacturers.”
    Restatement (Third) of Torts: Products Liability §2, Reporters’ Note,
    at 80-81 (1998), citing D. Owen, Defectiveness Restated: Exploding
    the ‘Strict’ Products Liability Myth, 1996 U. Ill. L. Rev. 743, 777.
    Our concern is less with the aspirational goal that might be set for
    manufacturers than with parties’ and jurors’ need for clarity. In effect,
    under the existing “unreasonably dangerous” test, jurors are asked to
    determine whether a product is too dangerous; under the proposed
    “not reasonably safe” test, they would be asked whether it is not safe
    enough. We find the former more likely to be understood by the
    average juror. See IPI Civil (2006) No. 400.01, Comment, at 553
    (noting that the phrase “not reasonably safe” might be
    interchangeable with “unreasonably dangerous,” but that the
    “Restatement, and Suvada and all its progeny, furnish persuasive
    authority that the jury should be instructed that it is the ‘unreasonably
    dangerous’ condition of the product which leads to liability”).
    By urging adoption of the Products Liability Restatement’s
    formulation of the elements of a strict product liability design defect
    claim, defendants seek a change in the substantive law of this state.
    This argument goes far beyond their assertion that the jury in this
    particular case was not properly instructed and would require our
    overruling Lamkin, Hansen, and Calles, at least in part. We,
    therefore, decline defendants’ invitation to adopt section 2(b) of the
    Products Liability Restatement. Thus, the existence of a feasible
    alternative design and the balancing of risks and benefits are relevant
    considerations in a strict product liability design defect case, but they
    are not elements of the claim that the plaintiff is required to plead and
    prove in every case.
    (3)
    We now turn to defendants’ alternative argument that even if the
    risk-utility test is not the sole, exclusive test for strict product liability
    -22-
    based on defective design, they are nevertheless entitled to a jury
    instruction on the risk-utility test under the circumstances of this case.
    We concluded in Calles that when a plaintiff’s claim cannot meet
    the consumer-expectation test, it may nevertheless be proven using
    the risk-utility test. Calles, 
    224 Ill. 2d
    at 256. No issue was raised in
    Calles regarding jury instructions because Calles came to us after a
    grant of summary judgment. We reversed that judgment and
    remanded for trial, but our analysis necessarily foreclosed
    consideration on remand of the consumer-expectation test for
    unreasonable dangerousness. Our holding required that only the risk-
    utility test be applied at trial. The result we reached in Calles leads to
    the inescapable conclusion that the present instruction on
    unreasonable dangerousness, IPI Civil (2006) No. 400.06, which
    focuses the jury’s inquiry on the use to which the product was being
    put at the time of the injury, is inappropriate in some cases. In order
    to ensure that the jury undertakes the appropriate inquiry when the
    consumer-expectation analysis does not apply, as in Calles, an
    instruction that incorporates consideration of risk and utility,
    including the feasibility of an alternative design, is required.
    The question posed in the present case is whether the same holds
    true when the consumer-expectation test is not foreclosed from jury
    consideration. In effect, defendants argue that the answer to the risk-
    utility test “trumped” the answer to the consumer-expectation test in
    Calles and that it should do so even when the consumer expectation
    test favors plaintiff and the risk-utility test favors the defendant. The
    only consideration, defendants claim, should be whether the issue of
    risk-utility has been raised by the evidence presented. Defendants rely
    on this court’s decision in Kerns, where we held that a nonpattern
    jury instruction on the feasibility of an alternative design was properly
    given because the trial court must instruct the jury on all issues raised
    by the evidence. 
    Kerns, 76 Ill. 2d at 164
    . See also Rios v. Navistar
    International Transportation Corp., 
    200 Ill. App. 3d 526
    , 537 (1990)
    (each party has the right to have the jury instructed on his theory of
    the case and the circuit court, in exercising its discretion, must
    instruct the jury on all issues that it finds have been raised by the
    evidence presented).
    Plaintiff responds that it is her choice whether to proceed under
    the “consumer-expectation theory” or the “risk-utility theory” of
    -23-
    design defect. She notes that “plaintiffs are masters of their complaint
    and are entitled to proceed under whichever theory they decide, so
    long as the evidence supports such a theory,” citing Reed v. Wal-Mart
    Stores, Inc., 
    298 Ill. App. 3d 712
    , 717-18 (1998). See also Barbara’s
    Sales, Inc. v. Intel Corp., 
    227 Ill. 2d 45
    , 59 (2007) (referring to
    plaintiffs as “masters of their complaint”). Plaintiff argues that it
    would be “utterly absurd” for defendants to “choose the theory
    plaintiff pursues at trial.” She states that she chose to try her case
    under “what is labeled the ‘consumer expectation’ theory of strict
    liability” rather than the other “form of strict liability,” risk-utility.
    She concludes that the trial court was not required to instruct the jury
    on “other potential theories of liability” that might have been
    available to her. Plaintiff further asserts that the instructions given
    accurately state that law and have never been modified because no
    modification has been needed.
    Plaintiff has confused theories of liability with methods of proof.
    This court has recognized three theories of strict product liability:
    manufacturing defect, design defect, and failure to warn. Sollami, 
    201 Ill. 2d
    at 7. In Hansen, the plaintiff claimed strict liability under both
    the failure to warn and design defect theories. 
    Hansen, 198 Ill. 2d at 423-24
    . Similarly, in Blue, the plaintiff pleaded two theories of
    liability–negligence and strict liability–but was forced to proceed only
    with the negligence claim because the strict liability claim was barred
    by the statute of repose. 
    Blue, 215 Ill. 2d at 81
    . In the present case,
    plaintiff has chosen to proceed under the design defect theory of strict
    product liability.
    In Lamkin, we stated that a plaintiff “may demonstrate that a
    product is defective in design, so as to subject a retailer and a
    manufacturer to strict liability for resulting injuries, in one of two
    ways.” 
    Lamkin, 138 Ill. 2d at 529
    . We then set out the consumer-
    expectation test and the risk-utility test. These two tests, therefore, are
    not theories of liability; they are methods of proof by which a plaintiff
    “may demonstrate” that the element of unreasonable dangerousness
    is met. See, e.g., Heastie v. Roberts, 
    226 Ill. 2d 515
    , 542 (2007)
    (explaining that the res ipsa loquitur doctrine is a “species of
    circumstantial evidence” that may be used to prove the element of
    breach of duty when the theory of liability is negligence).
    -24-
    In the present case, plaintiff elected to proceed under a theory of
    strict product liability based on design defect and not to pursue a
    negligence claim. She also chose to rely on the consumer-expectation
    method of proof, as demonstrated by the jury instructions she
    submitted. Defendants are not asserting that they have the right to
    choose plaintiff’s theory of liability. Rather, defendants are asserting
    that they, too, have the right to put on their case using any permissible
    method of proof. When the record contains evidence relevant to their
    chosen method of proof, they insist that they are entitled to a
    corresponding jury instruction. Their tendered instruction, defendants
    claim, is the only way to ensure that the jury utilizes the proper
    analytical framework to test the evidence before it.
    These arguments pose two questions for this court. First, is a
    defendant entitled to an instruction on the risk-utility test over the
    objection of a plaintiff whose chosen method of proof is consumer
    expectation? Second, if both consumer-expectation and risk-utility
    instructions are given and the tests yield inconsistent answers, which
    result prevails?
    “[T]he parties are entitled to have the jury instructed on the issues
    presented, the principles of law to be applied, and the necessary facts
    to be proved to support its verdict.” Dillon v. Evanston Hospital, 
    199 Ill. 2d 483
    , 505 (2002). The threshold for giving an instruction in a
    civil case is “not a high one.” 
    Heastie, 226 Ill. 2d at 543
    .
    “Generally speaking, litigants have the right to have the jury
    instructed on each theory supported by the evidence. Whether
    the jury would have been persuaded is not the question. All
    that is required to justify the giving of an instruction is that
    there be some evidence in the record to justify the theory of
    the instruction. The evidence may be insubstantial.” 
    Heastie, 226 Ill. 2d at 543
    .
    The decision to give or deny a tendered instruction is within the
    discretion of the trial court. 
    Dillon, 199 Ill. 2d at 505
    . So long as the
    tendered instructions clearly and fairly instruct the jury, a party is
    entitled to instructions on any theory of the case that is supported by
    the evidence. Snelson v. Kamm, 
    204 Ill. 2d 1
    , 27 (2003). As the
    appellate court has noted, “[i]t is within the discretion of the trial
    court to determine which issues are raised by the evidence presented
    -25-
    and which jury instructions are thus warranted.” Brdar v. Cottrell,
    Inc., 
    372 Ill. App. 3d 690
    , 704 (2007).
    The expression “theory of the case” does not refer to the
    plaintiff’s theory of liability. It refers, instead, to each party’s framing
    of the issues and arguments in support of its position. It is, therefore,
    well established that while a plaintiff is entitled to an instruction
    setting out her own theory of the case, based on her theory of liability
    and her chosen method of proof, she may not unilaterally preclude the
    giving of a jury instruction that presents the defendant’s theory of the
    case, so long as the defendant’s instruction accurately states the law
    and is supported by the evidence. Assuming, for now, that
    defendants’ tendered instructions met these criteria, we consider the
    implications of giving a jury both consumer-expectation and risk-
    utility instructions in a design defect case.
    If a jury were to consider the two tests independently, there are
    four possible outcomes. First, the product could be found
    unreasonably dangerous under both tests and judgment would be for
    the plaintiff. This was the case in Hansen, where the design of a
    complex medical device was at issue. 
    Hansen, 198 Ill. 2d at 435
    -36.
    Second, the product could be found not unreasonably dangerous
    under either test and judgment would be for the defendant. This was
    the case in Lamkin, where the design of a window screen was at issue.
    
    Lamkin, 138 Ill. 2d at 529
    -31.
    Third, the product could be found not unreasonably dangerous
    under the consumer-expectation test, but unreasonably dangerous
    under the risk-utility test. In such a case, judgment would be for the
    plaintiff. This is the possible outcome of Calles on remand, where the
    design of a utility lighter was at issue. Calles, 
    224 Ill. 2d
    at 256.
    Defendants in the present case posit the fourth possible outcome
    when the two tests are applied independently. The product could be
    found unreasonably dangerous under the consumer-expectation test,
    but risk-utility analysis could reveal that an alternative is not
    available, or that available alternatives are not feasible, or that the
    benefits of the design outweigh its inherent risks. In such a case,
    defendants argue, the result of the risk-utility test should trump the
    result of the consumer-expectation test. Defendant argues that if the
    tests are treated as alternatives so that a plaintiff may prevail by
    -26-
    meeting either test, the effect will be to impose absolute–not just
    strict–liability. This will occur, defendants claim, because the
    consumer-expectation test will, at least where a complex product is
    involved, almost always lead to a finding of unreasonable
    dangerousness. As a result, defendants will be liable for all injuries
    in all circumstances, no matter how much the risk-utility balance
    weighs in favor of the challenged product design.
    Defendants cite Mele v. Howmedica, Inc., 
    348 Ill. App. 3d 1
    (2004), and Besse v. Deere & Co., 
    237 Ill. App. 3d 497
    (1992), in
    support of this argument. These cases have been overruled, at least to
    the extent they relied on Scoby, by our decision in Calles. See Calles,
    
    224 Ill. 2d
    at 260 (listing appellate court decisions, including Mele,
    Besse, and Wortel, that had followed the “so called ‘simple product’
    exception” of Scoby). Nevertheless, defendants point to the appellate
    court’s efforts in Mele and Besse to fashion an “integrated test” for
    design defect, combining the consumer-expectation test and the risk-
    utility test.
    In Besse, the defendant appealed from a judgment of strict
    liability due to defective design of a cornpicker, arguing that the
    elements of unreasonable dangerousness and proximate causation
    were not proven. 
    Besse, 237 Ill. App. 3d at 499
    . The plaintiff
    presented evidence that the loss of her leg could have been prevented
    with a simple design modification that would not have hindered the
    machine’s function and that the necessary technology was available
    to the defendant when the machine was manufactured. Besse, 237 Ill.
    App. 3d at 501. The defendant argued on appeal that the machine
    operated exactly as it was designed to operate and, therefore, it could
    not be found unreasonably dangerous under the consumer-expectation
    test. 
    Besse, 237 Ill. App. 3d at 500
    . The appellate court noted that the
    “narrow test” set out in comment i to section 402A of the
    Restatement (Second) of Torts (1965) is not a complete statement of
    the law in Illinois. Rather, the court observed, “a broader definition
    of ‘unreasonably dangerous’ is available to the products liability
    plaintiff,” and this broader definition “embraces both the ‘consumer
    expectation’ test and a ‘risk/utility analysis’ test.” Besse, 
    237 Ill. App. 3d
    at 500. The two tests, according to the Besse court, are “not
    mutually exclusive.” Besse, 
    237 Ill. App. 3d
    at 501. The evidence
    presented in Besse “presented a factual question of whether the
    -27-
    product was unreasonably dangerous when analyzed under the
    integrated consumer expectation test and risk/benefit analysis test,”
    and the jury found this “integrated” test met by the plaintiff’s
    evidence. Besse, 
    237 Ill. App. 3d
    at 501.
    No issue was raised in Besse regarding jury instructions.
    However, despite its misplaced reliance on Scoby (Besse, 237 Ill.
    App. 3d at 501-02), we agree with the Besse court that the two tests
    are not mutually exclusive and may be applied together if the
    evidence supports it.
    In Mele, the manufacturer of a medical device implanted in a
    patient as part of a hip replacement procedure was held strictly liable
    on a theory of defective design. The plaintiff utilized the consumer-
    expectation method of proof, arguing to the jury that the device “did
    not perform as safely as an ordinary implantee would expect.” The
    plaintiff objected, successfully, to the defendant’s attempt “to show
    that the benefits of the product outweighed its risks.” Mele, 348 Ill.
    App. 3d at 8.
    The appellate court noted that to “show that a product is
    unreasonably dangerous due to a defective design, a plaintiff must
    present evidence that the design includes ‘a defect which subjects
    those exposed to the product to an unreasonable risk of harm.’ ”
    (Emphasis omitted.) 
    Mele, 348 Ill. App. 3d at 13
    , quoting Hunt v.
    Blasius, 
    74 Ill. 2d 203
    , 211 (1978). A plaintiff may make this
    showing in either of two ways: consumer expectation or risk utility.
    
    Mele, 348 Ill. App. 3d at 14
    . The defendant urged the court to adopt
    section 6(c) of the Products Liability Restatement, which would apply
    a risk-utility test to strict liability claims involving prescription drugs
    or medical devices. 
    Mele, 348 Ill. App. 3d at 15-16
    . The court
    rejected this suggestion because adoption of section 6(c) would
    “completely eliminate[ ] appraisal of the consumer’s expectations
    from determination of whether a medical device is unreasonably
    dangerous.” The section, therefore, “conflicts with Illinois law.”
    
    Mele, 348 Ill. App. 3d at 16
    .
    The Mele court next considered the defendant’s argument that the
    trial court erred by excluding all evidence of the risks and benefits of
    the device. The trial court found this evidence irrelevant because the
    plaintiff “sought to prove only that defendant’s product failed to meet
    the ordinary consumer’s expectations for the safety of the product”
    -28-
    and specifically decided not to seek to prove the design “unreasonably
    dangerous by showing its risks outweighed its benefits.” 
    Mele, 348 Ill. App. 3d at 17
    . The court noted that there was “no Illinois authority
    on the issue of whether a defendant may present evidence that the
    benefits of a product’s design outweigh its risks when a plaintiff
    argues that the product is unreasonably dangerous because it fails to
    meet ordinary consumer expectations for its safety.” Mele, 348 Ill.
    App. 3d at 17. After exploring the evolution of the two tests, the court
    cited Besse for the proposition that when a plaintiff alleges a design
    defect in a complex product, the product’s danger should be evaluated
    “using a test that incorporates both the ordinary consumer’s
    expectations and the risks and benefits of the product.” Mele, 348 Ill.
    App. 3d at 19. After further discussion related to medical devices in
    particular, the Mele court concluded that the trial court erred by
    excluding evidence of the risks and benefits of the hip replacement
    device. The evidence contained in defendant’s offer of proof could
    have shown “that the product was not unreasonably dangerous under
    the integrated test recommended in Besse.” 
    Mele, 348 Ill. App. 3d at 20
    . The appellate court, therefore, reversed the judgment of the trial
    court and remanded for retrial. 
    Mele, 348 Ill. App. 3d at 20
    -21.
    No issue was raised in Mele regarding jury instructions. However,
    Mele does suggest that even when a plaintiff chooses to proceed
    under the consumer-expectation test, she cannot dictate the
    defendant’s method of proving its case by preventing the admission
    of evidence relevant to the risk-utility analysis. We agree with Mele
    in this regard.
    In the present case, both parties presented evidence relevant to the
    risk-utility inquiry, so the question is whether, having argued that the
    risk-utility evidence favors its position, defendant is entitled to have
    the jury specifically instructed on the test. We conclude that this
    question is resolved by examining the scope of each inquiry.
    The consumer-expectation test is a single-factor test and,
    therefore, narrow in scope. See 
    Besse, 237 Ill. App. 3d at 500
    (describing the consumer-expectation test as “narrow”). The jury is
    asked to make a single determination: whether the product is unsafe
    when put to a use that is reasonably foreseeable considering its nature
    and function. IPI Civil (2006) No. 400.06. No evidence of ordinary
    consumer expectations is required, because the members of the jury
    -29-
    may rely on their own experiences to determine what an ordinary
    consumer would expect. 
    Mele, 348 Ill. App. 3d at 14
    .
    The risk-utility test, in contrast, is a multifactor analysis and,
    therefore, much broader in scope. Under an “integrated” test, as
    envisioned by the Mele and Besse courts, consumer expectations are
    but one of the factors to be considered. 
    Mele, 348 Ill. App. 3d at 20
    ;
    Besse, 
    237 Ill. App. 3d
    at 501.
    Although we have declined to adopt section 2 of the Products
    Liability Restatement as a statement of substantive law, we do find its
    formulation of the risk-utility test to be instructive. Under section
    2(b), the risk-utility balance is to be determined based on
    consideration of a “broad range of factors,” including “the magnitude
    and probability of the foreseeable risks of harm, the instructions and
    warnings accompanying the product, and the nature and strength of
    consumer expectations regarding the product, including expectations
    arising from product portrayal and marketing,” as well as “the likely
    effects of the alternative design on production costs; the effects of the
    alternative design on product longevity, maintenance, repair, and
    esthetics; and the range of consumer choice among products.”
    (Emphasis added.) Restatement (Third) of Torts: Products Liability
    §2, Comment f, at 23 (1998).
    This formulation of the risk-utility test is an “integrated” test of
    the kind envisioned by the appellate court in Mele and Besse. Under
    this formulation, consumer expectations are included within the scope
    of the broader risk-utility test. In addition, the test refines the
    consumer-expectation factor by specifically allowing for advertising
    and marketing messages to be used to assess consumer expectations.
    We adopt this formulation of the risk-utility test and hold that
    when the evidence presented by either or both parties supports the
    application of this integrated test, an appropriate instruction is to be
    given at the request of either party. If, however, both parties’ theories
    of the case are framed entirely in terms of consumer expectations,
    including those based on advertising and marketing messages, and/or
    whether the product was being put to a reasonably foreseeable use at
    the time of the injury, the jury should be instructed only on the
    consumer-expectation test.
    -30-
    Adoption of this integrated test resolves the question of whether
    the answer to the risk-utility test “trumps” the answer to the
    consumer-expectation test because the latter is incorporated into the
    former and is but one factor among many for the jury to consider.
    This is consistent with our conclusion in Calles that while a plaintiff
    might not prevail under the single-factor test, she might still prevail
    under the multifactor test. See Calles, 
    224 Ill. 2d
    at 256.
    In sum, we hold that both the consumer-expectation test and the
    risk-utility test continue to have their place in our law of strict product
    liability based on design defect. Each party is entitled to choose its
    own method of proof, to present relevant evidence, and to request a
    corresponding jury instruction. If the evidence is sufficient to
    implicate the risk-utility test, the broader test, which incorporates the
    factor of consumer expectations, is to be applied by the finder of fact.
    In the present case, the occupant of the car seat was killed when
    the car was struck from behind. Rear-end collisions are reasonably
    foreseeable and the ordinary consumer would likely expect that a seat
    would not collapse rearward in such an accident, allowing the
    occupant to sustain massive head injury. Thus, the jury concluded that
    the car seat was unreasonably dangerous because it proved “unsafe
    when put to a use that is reasonably foreseeable considering the
    nature and function of the product.” See IPI Civil (2006) No. 400.06.
    If the evidence presented was sufficient to require the jury to engage
    in risk-utility analysis, this conclusion as to consumer expectations
    would be properly considered as one factor in the broader, integrated
    risk-utility analysis.

    In Kerns, the plaintiff lost an eye when he was struck by a wire
    that was part of the power takeoff assembly of a forage blower.
    
    Kerns, 76 Ill. 2d at 159
    . He presented evidence of an alternative
    design. 
    Kerns, 76 Ill. 2d at 164
    . This court held that the trial court
    properly gave the defendant’s nonpattern instruction on feasibility,
    over the plaintiff’s objection. 
    Kerns, 76 Ill. 2d at 164
    .
    A familiar treatise cites Kerns for the following proposition:
    “In a products liability action for injuries caused by a
    defective product, the instructions must state correctly the
    -31-
    legal principles applicable to the case. The instructions should
    state the correct issues and should be supported by the
    evidence.” 30A Ill. L. & Prac. Products Liability §91,
    Instructions, at 146-47 (1994).
    We must next consider whether the trial court erred by refusing
    to give the nonpattern instruction tendered by the defendants. This
    requires us to determine: (a) if defendants’ tendered nonpattern
    instructions were adequate to preserve the jury instruction issue for
    review on appeal, (b) if the evidence was sufficient to support the
    giving of an instruction on the risk-utility test, and (c) if these criteria
    are met, whether the trial court’s refusal to instruct the jury on the
    risk-utility test is error requiring a new trial.
    (a)
    A party forfeits the right to challenge a jury instruction that was
    given at trial unless it makes a timely and specific objection to the
    instruction and tenders an alternative, remedial instruction to the trial
    court. Deal v. Byford, 
    127 Ill. 2d 192
    , 202-03 (1989). These
    requirements ensure that the trial court has the opportunity to correct
    a defective instruction and to prevent the challenging party from
    gaining an unfair advantage by failing to act when the trial court
    could remedy the faulty instruction and then obtaining a reversal on
    appeal. Morus v. Kapusta, 
    339 Ill. App. 3d 483
    , 489 (2003).
    Thus, in Morus, the defendant was found not to have forfeited his
    right to challenge a jury instruction on damages for reduced life
    expectancy because the instruction had been “a central topic of debate
    among the parties and the trial court at several junctures,” the
    defendant specifically objected to the instruction, and the defendant
    “also submitted an instruction to the court on this issue.” The
    appellate court, therefore, found the jury instruction issue preserved
    for review. 
    Morus, 339 Ill. App. 3d at 489-90
    .
    In the present case, defendants objected to plaintiff’s version of
    IPI Civil No. 400.06, which was given by the trial court:
    “When I use the expression ‘unreasonably dangerous’ in
    these instructions, I mean unsafe when put to a use that is
    reasonably foreseeable considering the nature and function of
    the car.”
    -32-
    This instruction is generally considered to express the consumer-
    expectation test because it does not call upon the jury to use anything
    outside its own experience to determine whether the product is
    defective because it is unsafe when used in a reasonably foreseeable
    manner.
    Defendants’ tendered nonpattern instructions numbers 17 and 29
    were refused:
    “A product is defective in its design when the foreseeable
    risks of harm posed by the product outweigh the benefits of
    the design and the risks can be avoided or reduced by the
    adoption of alternative feasible design. Feasible alternative
    designs must be available at the time that the product left the
    control of the defendant.
    Feasibility includes not only elements of economy,
    effectiveness, and practicality, but also technological
    possibilities under the state of the manufacturing art at the
    time the product was produced.”
    “When evaluating the reasonableness of a design
    alternative, the overall safety of the product must be
    considered. It is not sufficient that the alternative design
    would have reduced or prevented the harm suffered by the
    plaintiff if it would also have introduced into the product
    other dangers of equal or greater magnitude. A product’s
    design may be reasonably safe even if the product is not
    accident proof.”
    Defendants note that despite this court’s recognition of the risk-
    utility test in Lamkin, Blue, and Calles, no corresponding pattern
    instruction has been developed. Thus, they argue, current pattern
    instructions no longer reflect Illinois law and a nonpattern instruction
    is necessary when the jury is required to assess the risk-utility of a
    product. Defendants support their tendered nonpattern instructions by
    citation to Supreme Court Rule 239(a) (177 Ill. 2d R. 239(a)
    (“Whenever IPI does not contain an instruction on a subject on which
    the court determines that the jury should be instructed, the instruction
    given in that subject should be simple, brief, impartial, and free from
    argument”)), Lamkin and its progeny, and to the Products Liability
    Restatement. See also Gordon v. Chicago Transit Authority, 128 Ill.
    -33-
    App. 3d 493, 501 (1984) (nonpattern instructions are permitted where
    the case presents a unique factual situation or point of law not
    addressed by the IPI and which requires clarification or
    amplification).
    Plaintiff responds that defendants’ nonpattern instructions are not
    an accurate statement of the law and, therefore, did not meet the
    threshold requirement of having tendered an alternative instruction
    that correctly states the legal principles applicable to the case.
    Specifically, plaintiff asserts that none of the “concepts” contained in
    the nonpattern instructions are part of the plaintiff’s burden of proof
    in a product liability case. Plaintiff also argues that the nonpattern
    instruction is confusing.
    Plaintiff is correct that a product liability plaintiff is not required
    to utilize the risk-utility method of proof and does not have a
    “burden” of proving the existence of a feasible alternative design. She
    does, however, have the burden of proving that the product is
    unreasonably dangerous due to a design defect. If, however, a product
    liability defendant introduces evidence that no feasible alternative
    design exists or that the design offers benefits that might outweigh its
    risks, the plaintiff who does not rebut such evidence with evidence of
    her own runs the risk that the trier of fact may resolve the issue
    against her. Given our fact-pleading rule (Iseberg v. Gross, 
    227 Ill. 2d 78
    , 87 (2007)), discovery procedures, and rules requiring the
    disclosure of witnesses (735 ILCS 5/2–1003 (West 2006); 
    210 Ill. 2d
    R. 201)), it should not come as a surprise to any product liability
    plaintiff that the defendant intends to utilize the risk-utility method of
    proof and to seek a corresponding jury instruction.
    Our review of the record reveals that the risk-utility test was a
    central topic of debate among the parties, the defendants specifically
    objected to plaintiff’s instruction on the consumer-expectation test,
    and the defendants submitted a nonpattern instruction on the risk-
    utility test. The tendered nonpattern instructions would not have
    placed a burden on the plaintiff to prove the existence of a feasible
    alternative design. In addition, plaintiff herself used evidence relevant
    to the risk-utility inquiry in her case in chief to bolster her consumer-
    expectation argument. She cannot have been surprised that defendants
    responded with evidence relevant to the risk-utility inquiry, argued to
    the jury that the benefits of the seat’s design outweighed its risks, and
    -34-
    sought an instruction that would have directed the jury’s attention to
    this inquiry. Further, we are not persuaded by plaintiff’s argument
    that the tendered nonpattern instruction is so flawed or confusing that
    it did not meet the standard set out in Deal. Defendants, therefore,
    have properly preserved for appeal the question of whether the
    evidence presented was sufficient to entitle them to have the jury
    instructed on the risk-utility test.
    (b)
    Each party has the right to have the jury clearly and fully
    instructed on any relevant theory of the case that is supported by the
    evidence. Leonardi v. Loyola University of Chicago, 
    168 Ill. 2d 83
    ,
    100 (1995). Thus, the second question that must be addressed in this
    section is whether the risk-utility test was sufficiently implicated by
    the evidence presented during the 2½-week trial that it would have
    been proper to give such an instruction. See 
    Heastie, 226 Ill. 2d at 543
    (“[a]ll that is required to justify the giving of an instruction is that
    there be some evidence in the record to justify the theory of the
    instruction”). This is a question that is readily answered by this
    court’s review of the record. 
    See 374 Ill. App. 3d at 650-53
    (appellate
    court’s summary of the testimony at trial).
    Defendants argue that the question of risk utility was raised by the
    evidence presented by both parties, specifically by the expert
    testimony regarding the feasibility of other seat designs, the results of
    crash tests, the commercial availability of cars with alternative seat
    designs at the time the Escort was manufactured, the risks posed by
    rigid seats, and the circumstances in which a yielding seat would be
    safer than a rigid seat. This evidence, defendants assert, was sufficient
    to justify a jury instruction on the risk-utility test.
    Plaintiff does not deny that the evidence was sufficient to meet
    this rather low threshold, but argues that it is her choice, as plaintiff,
    whether to proceed under the “consumer-expectation theory” or the
    “risk-utility theory” of design defect.
    As noted above, plaintiff has chosen her theory of liability (design
    defect) and her method of proof (consumer expectation). She may not
    -35-
    choose defendants’ theory of defense (absence of design defect, lack
    of proximate cause) or their method of proof (risk utility).
    We conclude, based on our review of the record, that sufficient
    evidence was presented at trial to raise an issue regarding the risk
    versus the utility of the CT20 seat design and to justify a
    corresponding jury instruction.
    (c)
    Having established that the tendered nonpattern instruction was
    adequate to preserve defendants’ jury instruction issue for appeal and
    that the evidence presented at trial was sufficient to justify the giving
    of an instruction on the risk-utility test, the question remains whether
    the trial court erred by refusing the tendered instruction.
    Plaintiff correctly notes that the standard of review on this issue
    is abuse of discretion. 
    Dillon, 199 Ill. 2d at 505
    . Defendants
    acknowledge that the trial court has discretion in instructing the jury,
    but assert that refusal to instruct the jury on a theory supported by the
    evidence, when that refusal prejudices the requesting party’s right to
    a fair trial, is an abuse of discretion (citing McCarthy, 
    355 Ill. App. 3d
    at 970). This prejudice-based formulation of the abuse of
    discretion standard is not one that this court has had occasion to use,
    although the standard has often been expressed in these terms by the
    appellate court. See, e.g., Smith v. Marvin, 
    377 Ill. App. 3d 562
    , 567
    (2007); Frigo v. Silver Cross Hospital & Medical Center, 377 Ill.
    App. 3d 43, 77 (2007); Barth v. State Farm Fire & Casualty Co., 
    371 Ill. App. 3d 498
    , 504 (2007); Schmidt v. Ameritech Illinois, 329 Ill.
    App. 3d 1020, 1031 (2002).
    We agree with the cited cases that when a party tenders a jury
    instruction that states the legal principles applicable to the case and
    that instruction is supported by the evidence, it is an abuse of
    discretion to refuse to give the instruction if the refusal prejudices the
    party’s right to a fair trial.
    On the merits, defendants claim the evidence showed that the
    designers of the CT20 seat had to take into account all of the various
    types of possible collisions (front-end, rear-end, side, rollover) that
    could occur at a wide range of speeds, and with occupants of different
    sizes, who may or may not be properly using their seatbelts,
    -36-
    positioned at various seats in the vehicle. This “complex set of
    considerations,” defendants assert, is not amenable to consumer-
    expectation analysis. As a result, they tendered the nonpattern
    instruction to focus the jury’s inquiry on the evidence regarding the
    availability of feasible alternative designs, the risk posed by the CT20
    seat, and the benefits of the CT20 design. If the court had given the
    tendered nonpattern risk-utility instruction instead of the pattern
    instruction, defendants posit, the jury would have been directed to
    weigh this evidence, including expert testimony that the yielding seat
    that caused James’s death might nevertheless have been a safer
    alternative for other drivers in other types of collisions. Defendants
    also point to testimony by one of their own experts that the yielding
    driver’s seat may have prevented fatal or more serious injury to the
    backseat passenger even while causing more serious injury to James.
    Defendants claim that they were prejudiced by the refusal of their
    instruction because the jurors were given no guidance as to how they
    were to assess the evidence and no instruction that directed them to
    balance risks and benefits. As a result, defendants argue, the jury’s
    deliberations were “untethered to any rule of law.” Under IPI Civil
    (2006) No. 400.06 as given, the jurors were merely asked to
    determine whether the seat was unsafe when used in a reasonably
    foreseeable manner, such as being stopped at a red light. Defendants
    posit that any jury would be likely to find the seat unreasonably
    dangerous under this standard, because the accident was fatal and
    because they were not specifically instructed to give due
    consideration to the evidence of benefits, risks, and alternative
    designs. As a result, the jury may have done “rough justice” based on
    their sympathy for the tragic death of a young husband and father,
    without considering, for example, the evidence that 99.6% of the cars
    on the road at that time were equipped with yielding seats.
    Plaintiff responds that she tendered the applicable pattern
    instructions in total compliance with Supreme Court Rule 239 and
    that no case of this court has ever held that an additional instruction
    setting out the risk-utility test is required. She relies on Carrillo v.
    Ford Motor Co., 
    325 Ill. App. 3d 955
    (2001), to argue that the trial
    court did not abuse its discretion.
    Carrillo involved the same mechanism of injury as the present
    case (a rear-end collision in which the driver of a Ford vehicle was
    -37-
    killed or injured when the car seat collapsed on impact), and the same
    theory of liability (product liability due to design defect). The same
    judge who presided in the present case gave the same jury
    instructions. (The jury instructions that were given in Carrillo were
    provided to the trial court in the present case and are part of the
    record.) The trial testimony in the two cases was similar, including
    testimony by some of the same expert witnesses for both sides. 
    See 374 Ill. App. 3d at 650-53
    ; 
    Carrillo, 325 Ill. App. 3d at 958-63
    . The
    Carrillo jury returned a verdict for the plaintiff and this judgment was
    affirmed on appeal.
    Ford argued on appeal that the trial court erred by refusing to give
    the following instruction, based on IPI Civil (2000) No. 400.07:
    “ ‘It is the duty of an automobile manufacturer to furnish
    a product which is in a reasonably safe condition when put to
    a use that was reasonably foreseeable considering its nature
    and intended function.’ ” 
    Carrillo, 325 Ill. App. 3d at 963-64
    ,
    quoting IPI Civil (2000) No. 400.07.
    The appellate court affirmed, for several reasons. First, the
    rejected instruction uses the expression “reasonably safe,” which
    suggests that the jury is to determine whether the product’s design is
    “not reasonably safe.” The court noted that this court had previously
    rejected the suggestion that this element of a strict liability claim
    should be expressed as “not reasonably safe” instead of
    “unreasonably dangerous.” 
    Carrillo, 325 Ill. App. 3d at 964
    , citing
    Dunham v. Vaughan & Bushnell Mfg. Co., 
    42 Ill. 2d 339
    , 343 (1969)
    (the test is whether the product is “unreasonably dangerous,” even
    though the expression “not reasonably safe” might be “[s]omewhat
    preferable”). Further, the expression “not reasonably safe” is
    inconsistent with IPI Civil (2000) No. 400.06 and the comments
    thereto. IPI Civil (2000) No. 400.06, Comment, at 620.
    Second, the appellate court found no Illinois decision, either from
    this court or the appellate court, that requires IPI Civil (2000) No.
    400.07 to be given in design defect cases.
    Third, IPI Civil (2000) No. 400.07 contains the word “duty,”
    which, the appellate court suggested, should be avoided in strict
    liability instructions because it tends to blur the distinction between
    strict liability and negligence. The appellate court noted the absence
    -38-
    of comments to this instruction, thus giving trial courts no guidance
    as to when it should be used. 
    Carrillo, 325 Ill. App. 3d at 965
    .
    (Partially in response to the concerns raised in Carrillo, the 2006
    edition of the IPI Civil has replaced instruction 400.07 with a notation
    that “The Committee recommends that no instruction concerning the
    duty of strict product liability defendants be given, except in cases
    where [instructions regarding the duty to warn] are applicable.” IPI
    Civil (2006) No. 400.07A.)
    The Carrillo court held that IPI Civil (2000) No. 400.06 fully,
    fairly and comprehensively informed the jury of all the relevant legal
    principles. 
    Carrillo, 325 Ill. App. 3d at 966
    .
    Plaintiff’s position is that if IPI Civil (2000) No. 400.06, standing
    alone, was a full, fair and comprehensive instruction in Carrillo,
    where the three-week trial included the same sort of evidence that
    was given in the present case, then it must also have been a full, fair,
    and comprehensive instruction in the present case. She insists that the
    trial court’s hands were tied by Carrillo, because if the trial court had
    given the requested nonpattern instructions, it would have been acting
    inconsistently with applicable precedent and that, itself, would have
    been error.
    We do not find Carrillo to be helpful. The nonpattern instruction
    tendered by defendants in the present case suffers from none of the
    infirmities affecting IPI Civil (2000) No. 400.07. In addition, the
    issue in Carrillo (whether a flawed pattern instruction should have
    been given) is not the same as whether a nonpattern instruction that
    states an applicable principle of law that has been implicated by the
    evidence should have been given.
    We find our decision in Dillon instructive. Dillon involved a
    medical malpractice claim against a physician, a hospital, and other
    defendants. When an intravenous catheter was removed from the
    plaintiff/patient, a nine-centimeter fragment of the catheter remained
    in her vein. It subsequently migrated to her heart, where the tip of the
    fragment became embedded in the heart wall. Removal of the
    fragment would have been more dangerous than leaving it in place.
    The jury returned a verdict for the plaintiff. Included in the damages
    award was $500,000 for the increased risk of future injuries that
    might result from leaving the catheter fragment in place. 
    Dillon, 199 Ill. 2d at 487-89
    .
    -39-
    The physician and the hospital argued on appeal that the trial
    court erred by giving a modified pattern jury instruction. Specifically,
    the trial court, at plaintiff’s request, added a sentence to the pattern
    instruction that directed the jury to take into consideration the
    “increased risk of future injuries” when calculating the amount of
    damages. 
    Dillon, 199 Ill. 2d at 497
    .
    As in the present case, the debate over the jury instruction issue
    reflected a larger debate over the applicable law. Prior to Dillon, this
    court had rejected the risk of future injury as an element of damages.
    
    Dillon, 199 Ill. 2d at 497
    -98. After a careful analysis of the history of
    this rule, the case law from Illinois and elsewhere, the scholarly
    literature, the split of authority in our appellate court, and policy
    (
    Dillon, 199 Ill. 2d at 497
    -504), we held that “a plaintiff must be
    permitted to recover for all demonstrated injuries,” including the risk
    of future injury. (Emphasis in original.) 
    Dillon, 199 Ill. 2d at 504
    . We
    explained that the burden was on the plaintiff to quantify the degree
    of risk and that amount of compensation must reflect the probability
    of the occurrence of future injury. 
    Dillon, 199 Ill. 2d at 504
    .
    We then turned to the issue of jury instructions. At that time, there
    was no pattern jury instruction on the increased risk of future injury
    as an element of damages. Because the pattern jury instructions were
    inadequate, an additional instruction was appropriate. Dillon, 
    199 Ill. 2d
    at 505. The instruction that was given, however, failed to fully and
    fairly convey the newly adopted principle of law. Dillon, 
    199 Ill. 2d
    at 506. The instruction merely told the jury to consider the “increased
    risk of future injuries”; it did not convey the principle that the jury
    should consider the degree of risk of that future harm occurring and
    adjust the damages amount proportionally to the degree of the risk.
    Dillon, 
    199 Ill. 2d
    at 506-07.
    In Dillon, a pattern jury instruction regarding damages was
    modified at plaintiff’s request. The jury found the defendants liable
    and awarded damages. Having “definitively spoken” to a disputed
    question of law, we determined that a retrial on the damages issue, “in
    which a jury may apply the correct legal principles to the submitted
    evidence, is appropriate,” because the jury “was inadequately
    instructed.” Dillon, 
    199 Ill. 2d
    at 507-08.
    In the present case, a nonpattern jury instruction was refused
    because the trial court determined that the risk-utility test did not
    -40-
    apply. The jury found defendants liable. We have definitively spoken
    to the questions of the applicability of the risk-utility test and its
    relationship to the consumer-expectation test. A retrial is required
    because the jury was inadequately instructed and was, therefore,
    unable to apply the correct legal principles to the submitted evidence.
    We conclude that defendants were prejudiced by the failure to
    give an instruction that would have caused the jury to apply the risk-
    utility test in addition to the consumer-expectation test. Although
    defendants were not prevented from introducing evidence regarding
    the risks and benefits of the alternative designs that were feasible at
    the time, and were not prevented from arguing to the jury that, on
    balance, the CT20 seat was not “unreasonably dangerous” because it
    prevented more injuries than it caused, the jury was specifically
    instructed to focus its deliberations solely on whether the seat was
    unsafe when put to a reasonably foreseeable use. The lack of a risk-
    utility instruction, combined with the use of IPI Civil (2000) No.
    400.06, prejudiced defendants’ ability to obtain a full, fair, and
    comprehensive review of the issues by the jury. We, therefore, hold
    that the trial court’s refusal to give the tendered instruction was an
    abuse of discretion.
    We note that this decision does not preclude a plaintiff in a design
    defect case from proving her case using the consumer-expectation
    test. Indeed, both parties may litigate an entire case using the
    consumer-expectation test if, for example, the dispositive issue is
    whether the manner in which the product was used was reasonably
    foreseeable. Our holding does mean that if either or both of the
    parties in a strict liability design defect case utilize risk-utility
    evidence as their method of proof, a corresponding jury instruction
    must be given if requested.
    (5)
    Given our conclusion that the judgment must be vacated and the
    matter remanded for a new trial, it is not necessary for us to address
    the question of whether the award for loss of society was excessive.
    CONCLUSION
    -41-
    In sum, we hold that both the consumer-expectation test and the
    risk-utility test may be utilized in a strict liability design defect case
    to prove that the product is “unreasonably dangerous.” Whether an
    instruction is required on either test or both tests will depend on the
    issues raised in the pleadings and the evidence presented at trial.
    When both tests are employed, consumer expectation is to be treated
    as one factor in the multifactor risk-utility analysis.
    Because the trial court abused its discretion by refusing the
    tendered nonpattern instructions, the judgment of the appellate court,
    which affirmed in part and reversed in part the judgment of the circuit
    court, is reversed, the judgment of the circuit court is reversed, and
    the cause is remanded to the circuit court for a new trial.
    Appellate court judgment reversed;
    circuit court judgment reversed;
    cause remanded.
    JUSTICE KILBRIDE took no part in the consideration or
    decision of this case.
    CHIEF JUSTICE FITZGERALD, concurring in part and
    dissenting in part:
    While I agree with the majority opinion in parts (1), (2), and
    (4)(a) and (b), I depart from the majority’s conclusion in sections (3)
    and (4)(c), particularly to the extent that it can be read to approve
    defendants’ tendered non-IPI instructions. Because I am not
    persuaded that defendants’ non-IPI instructions were superior to
    plaintiff’s approved IPI instructions in guiding the jury’s
    consideration of the issues in this case, I do not believe the trial court
    abused its discretion. Instead, I believe the IPI instructions–along with
    the arguments of counsel based upon the evidence
    presented–provided an adequate framework to allow the members of
    the jury to reach the ultimate issue. Therefore, I depart from the
    majority because I cannot find that the jury was clearly misled or that
    the defendant was prejudiced. My basis for that opinion rests largely
    upon matters in the record not addressed by the majority’s opinion,
    namely, the arguments of counsel and the faultiness of defendants’
    instructions.
    As required by Illinois Pattern Jury Instructions, Civil, No. 400.06
    (2006), the trial court gave the jury an instruction requiring it to find
    in favor of plaintiffs on a strict liability theory if, inter alia, the seat
    was “unreasonably dangerous” in the sense that it was “unsafe when
    put to a use that is reasonably foreseeable considering the nature and
    function” of the seat. IPI Civil (2006) No. 400.06. In contrast, Ford’s
    issues and burden instructions submitted to the court stated that the
    issue was whether “the design defect made the Escort unreasonably
    dangerous” and that “on balance the benefits of the 1996 Escort’s
    front seat design outweigh the risks of danger inherent in the design.”
    Defendants’ definition instruction No. 27 stated, in part,
    “[A] product is defective in design when the foreseeable risks
    of harm posed by the product outweigh the benefits of the
    design and the risks can be reduced or avoided by the
    adoption of an alternative feasible design. Feasibility includes
    not only elements of economy, effectiveness and practicality,
    but also technological possibilities under the state of
    manufacturing art at the time the product was produced.”
    Defendants’ definition instruction No. 28 stated,
    “[W]hen evaluating the reasonableness of a design
    alternative, the overall safety of the product must be
    considered. It is not sufficient that the alternative design
    would have reduced or prevented the harm suffered by the
    plaintiff if it would also have introduced into the product
    other dangers of equal or greater magnitude. A product’s
    design may be reasonably safe even if the product is not
    accident proof.”
    Both plaintiff’s and defendants’ instructions must be evaluated to
    determine whether the trial court abused its discretion.
    Illinois Supreme Court Rule 239(a) governs the choosing of
    instructions and provides that the court should consider the facts and
    law and “shall” use the IPI unless it determines that it does not
    accurately state the law. 177 Ill. 2d R. 239(a). A reviewing court will
    reverse a trial court’s determination about which instruction to give
    upon an abuse of discretion. Schultz v. Northeast Illinois Regional
    Commuter R.R. Corp., 
    201 Ill. 2d
    260, 273 (2002). We will examine
    the jury instructions in their entirety, to determine whether they fairly,
    -43-
    fully and comprehensively informed the jury of the relevant law.

    at 273-74. Ordinarily, we will not reverse a trial
    court, even if the trial court gave faulty instructions, unless the
    instructions clearly misled the jury and resulted in prejudice to the
    appellant. Schultz, 
    201 Ill. 2d
    at 274; Dillon v. Evanston Hospital,
    
    199 Ill. 2d 483
    , 507 (2002).
    Our jurisprudence recognizes counsel has some role to play in
    helping the jury to understand the instructions given by the judge. As
    is stated in the foreward to the first edition of the Illinois Pattern Jury
    Instructions, Civil, “on many occasions when the Committee has
    rejected an instruction it has felt not so much that the point ought not
    to be told to the jury, but rather it should be told to the jury by counsel
    rather than by the Court.” (Emphasis in original.) See IPI Civil
    (2006), at xxii (foreward to the first edition). This court echoed that
    idea in Schultz v. Northeast Illinois Regional Commuter R.R. Corp.,
    
    201 Ill. 2d
    260 (2002). In Schultz, the court concluded that the trial
    court erred in giving an IPI instruction. Schultz, 
    201 Ill. 2d
    at 281.
    Nevertheless, the court held that the trial court’s failure to properly
    instruct the jury was not reversible error and noted the appellate
    court’s judgment may be affirmed on any basis in the record. Schultz,
    
    201 Ill. 2d
    at 281. We found that it was not clear from the record that
    the jury was misled by the error. Schultz, 
    201 Ill. 2d
    at 281. We noted
    that the trial court allowed defense counsel to discuss in closing
    argument evidence regarding defendant’s rejected instruction, and
    noted that defense counsel did so, emphasizing that evidence in the
    framework of the instructions given by the court. Schultz, 
    201 Ill. 2d
    at 282.
    This idea that the arguments can supplement the jury instruction
    is also found in Carrillo v. Ford Motor Co., 
    325 Ill. App. 3d 955
    (2001). As the majority notes, the Carrillo case involves nearly
    identical facts, the same lawyers, trial judge, and experts as the instant
    matter. More importantly, the instructions against Ford were identical
    in both trials: the court gave plaintiff’s tendered IPI instruction nos.
    400.01, 400.02 and 400.06 and refused to give defendant’s
    instruction, IPI Civil No. 
    400.07. 325 Ill. App. 3d at 963-64
    . The
    court noted, however, that defense counsel’s arguments were
    sufficient when it stated “IPI Civil (2000) No. 400.06 told the jury a
    product is unreasonably dangerous only when put to a use that is
    -44-
    reasonably foreseeable. [Citation.] Ford was free to argue and did
    argue that Lydia’s accident was of a rare type. Both sides presented
    lengthy and conflicting testimony from a long list of experts. The jury
    made its decision.” (Emphasis added.) 
    Carrillo, 325 Ill. App. 3d at 965
    -66. Therefore, following Carrillo, the foreward to the first
    edition of the Illinois Pattern Jury Instructions, and Schultz, I find IPI
    Civil (2006) No. 400.06 can provide an adequate framework to
    deliver the appropriate legal guidance to the jury if counsel was
    permitted to make arguments pertaining to the rejected instruction.
    Looking at the record, it is clear that counsel emphasized the
    risks and benefits of the CT20 seat. The majority recounted the
    extensive evidence submitted to the jury regarding the benefits and
    dangers of the CT20 seat, as well as Timberlake’s role in the accident.
    The defense counsel was free to argue, and did argue extensively, that
    the “balance” of the risks of an alternate seat design outweighed the
    benefits such that the CT20 seat was not “unreasonably dangerous.”
    I note also that defense counsel devoted some argument on the
    proximate cause issue to Timberlake’s role as the potential sole
    proximate cause of the accident, as a drunk driver of a Cadillac
    speeding at 60 miles per hour into the back of a standing Ford Escort.
    Based upon the use of IPI Civil (2006) Nos. 400.01, 400.02 and
    400.06 and arguments from counsel, there is no indication that the
    jury was clearly misled and that defendants were prejudiced. Schultz,
    
    201 Ill. 2d
    at 274. The general instruction contains nothing which
    would prevent the jury from considering the defense experts’
    testimony that a different seat design would have introduced a host of
    dangers. Certainly, if the jurors had credited the defense experts and
    discredited the plaintiff’s experts, the jury had the proper legal
    framework to find that seat was allowably dangerous–dangerous to
    some consumers like Mikolaczyck perhaps–but not unreasonably
    dangerous considering the nature and function of the seat in relation
    to all possible accidents that could occur.
    Further, there is no indication that the jury could not make some
    form of a risk/benefit analysis in coming to its decision. That
    determination is not beyond the ken of the jury given adequate expert
    testimony. Indeed, it would be difficult to find that a jury conducted
    an adequate reasonableness analysis without simultaneously
    conducting a risk/benefit analysis. The jury could have concluded that
    -45-
    the risks of the current seat to James Mikolajczyck’s life were not
    outweighed by the benefits of some other hypothetical lives that
    would have been saved. Whether it performed that balance correctly
    is beyond the purview of this opinion as it relates to a manifest weight
    of the evidence argument, which was not raised by the defense
    counsel before the appellate court or this court.
    Turning to defendants’ instructions, I believe that the trial court
    correctly rejected the non-IPI instructions. First, read as a whole, the
    conspicuous problem with the defendants’ instructions is that they
    deny plaintiff her chosen method of proof: consumer expectations.
    Rather, it appears the defendants’ strategy was the adoption of the
    risk-utility test as the sole test for products liability. In fact, defendant
    appears to have admitted as much to the appellate court (see 369 Ill.
    App. 3d 78, 87) and contains no argument before this court that the
    consumer expectations test should be retained. There was no basis in
    precedent for the trial court to force plaintiff to abandon her choice of
    the consumer expectations test.
    I note also that defendants’ instruction departs from the majority’s
    possible formulation of the risk utility test (see slip op. at 30), which
    includes “ ‘the nature and strength of consumer expectations
    regarding the product, including expectations arising from product
    portrayal and marketing.’ ” (Emphasis omitted.) Slip op. at 30,
    quoting Restatement (Third) of Torts: Products Liability §2,
    Comment f, at 23 (1998). I agree with the majority that the “consumer
    expectation” test should not be abandoned. But I also note that the
    Third Restatement does not itself propose a jury instruction.
    Restatement (Third) of Torts: Products Liability §2, Comment f, at 25
    (“This Restatement takes no position regarding the specifics of how
    a jury should be instructed. So long as jury instructions are generally
    consistent with the rule of law set forth in Subsection (b), their
    specific form and content are matters of local law”); Comment f,
    Illustration 6, at 25 (1998) (“Whether instructions to the trier of fact
    should include specific reference to these factors is beyond the scope
    of this Restatement and should be determined under local law”)
    (1998).
    Next, defendants’ instructions contain an inaccurate statement of
    the law in their burden shifting language in instruction 19. The
    relevant portion of that instruction provides: “If you find from your
    -46-
    consideration of all the evidence that each of these propositions has
    been proved, then the burden shifts to Ford/Mazda to prove that on
    balance the benefits of the 1996 Escort’s front seat design outweigh
    the risks inherent in the design.” The burden of proof does not shift
    to Ford/Mazda. Rather, the ultimate burden remains with the plaintiff
    to prove that the car seat was unreasonably dangerous. The majority
    notes that no decision of this court has ever expressly adopted this
    burden-shifting formulation, and rejects that position in its opinion.
    Slip op. at 14-15.
    Defendants’ non-IPI instruction No. 28 was also problematic in
    that it, inter alia, provided “a product’s design may be reasonably
    safe even if the product is not accident proof.” I note that this
    language–“reasonably safe”–has not been approved in Illinois
    precedent, and the majority has rejected it for lack of clarity. Slip op.
    at 22 (noting that the phrase “ ‘not reasonably safe’ might be
    interchangeable with ‘unreasonably dangerous,’ but that the
    ‘Restatement, and Suvada and all its progeny, furnish persuasive
    authority that the jury should be instructed that it is the “unreasonably
    dangerous” condition of the product which leads to liability’ ”),
    quoting IPI Civil (2006) No. 400.01, Comment, at 553. As the
    majority notes, this language amounts to adoption of section 2(b) of
    the Restatement (Third) and would necessarily overrule Lamkin,
    Hansen, and Calles. Slip op. at 22. Furthermore, the words “not
    accident proof” are argumentative in that they have no source in
    Illinois law, according to my research, and could render any product
    not “unreasonably dangerous,” as every product can meet the standard
    of not being accident proof.
    As such, the trial judge faced the possibility that the jury would
    have been misled and the plaintiff would have been prejudiced had
    defendants’ instructions been used. Therefore, had the trial judge
    been dissatisfied with plaintiff’s IPI instructions, the defendants’ non-
    IPI instructions would have presented greater difficulties in giving the
    jury an accurate statement of the law.
    Lastly, I find Dillon distinguishable. In Dillon, we held that the
    jury instructions on damages including the phrase “the increased risk
    of future injuries” failed to instruct the jury properly. The holding in
    Dillon was at odds with this court’s historical rejection of recovery
    for risk of future injuries. 
    Dillon, 199 Ill. 2d at 497
    . There also was a
    -47-
    split of authority in the appellate court. Dillon, 
    199 Ill. 2d
    at 498.
    Having determined for the first time that the element of damages was
    compensable, the court then turned to whether the jury instruction
    was proper. 
    Dillon, 199 Ill. 2d at 504
    . This court did not address the
    supplementation of the jury instructions with adversarial emphasis
    during argument. Further, we deemed the instruction faulty because
    it failed to distinctly instruct the jury regarding the amount of possible
    future damage multiplied by the probability that it would occur.
    Dillon, 
    199 Ill. 2d
    at 507. There was no indication in Dillon that this
    was supplemented by the arguments of counsel. Here, this court had
    not spoken on this specific issue, there was no split in authority in the
    appellate court, and the parties were able to supply adversarial
    emphasis. I therefore cannot find that the trial court abused its
    discretion as the jury was not clearly misled and the defendants were
    not prejudiced by the use of the IPI instruction.
    I therefore depart from sections 3 and 4(c) of the majority opinion
    as those sections rest on the assumption that defendants’ instruction
    were superior to plaintiff’s instructions and fail to consider the effect
    of defense counsel’s argument. See slip op. at 25-26 (stating the trial
    judge “may not unilaterally preclude the giving of a jury instruction
    that presents the defendant’s theory of the case, so long as the
    defendant’s instructions accurately state the law and is supported by
    the evidence. Assuming, for now, that defendants’ tendered
    instructions met these criteria, we consider the implications of giving
    a jury both consumer-expectation and risk-utility instructions in a
    design defect case”). Accordingly, I believe that the trial court did not
    abuse its discretion in choosing plaintiff’s IPI instructions over
    defendants’ non-IPI instructions. I therefore respectfully dissent.
    Dissent Upon Denial of Rehearing
    CHIEF JUSTICE FITZGERALD, dissenting:
    Among plaintiff’s arguments on rehearing under Supreme Court
    Rule 367(b) (
    210 Ill. 2d
    R. 367(b)) are that the court “overlooked or
    misapprehended” the faultiness of the defendants’ instructions and
    the majority silently overruled prior precedent of this court as found
    in Calles v. Scripto-Tokai Corp., 
    224 Ill. 2d 247
    (2007), Hansen v.
    -48-
    Baxter Healthcare Corp., 
    198 Ill. 2d 420
    (2002), and Lamkin v.
    Towner, 
    138 Ill. 2d 510
    (1990). I agree with these points and
    additionally find that they are not reargument of the case. I therefore
    respectfully dissent upon denial of rehearing.
    Plaintiff first asserts that defendants’ alternate instructions
    misstated the law in seven respects, including some of those I noted
    in my dissent. Defendants’ instructions improperly: (1) required
    plaintiff to prove there was an alternative feasible design in existence
    at the time defendant sold the product in order to impose liability; (2)
    misstated the law for proving risk-utility in that they stated that the
    burden shifts to defendants to prove that the benefits of the design
    outweighs its risks; (3) failed to correctly state the majority’s
    “integrated test” because defendants’ instructions did not include any
    reference to consumer expectation; (4) required the plaintiff to prove
    the product was “unreasonably dangerous” without a definition of the
    phrase; (5) required the plaintiff to prove both that the vehicle had a
    “design defect” and the vehicle was “unreasonably dangerous”; (6)
    used the phrase “not reasonably safe,” which this court rejected as an
    inadequate substitute for “unreasonably dangerous”; and (7)
    contained an argumentative reference to a product being reasonably
    safe even if it is not “accident proof.” I note that these liability
    instructions were the topic of extensive discussion before and during
    the trial. Therefore, unaddressed by the majority opinion is the trial
    court’s consideration of whether plaintiff would have suffered serious
    prejudice had the trial court opted for defendants’ instructions. A
    principal result of this omission is that the majority opinion can be
    read as approving defendants’ instructions. For that reason alone,
    plaintiffs have presented a strong case to grant rehearing in order to
    remove this court’s possible imprimatur on defendants’ instructions.
    The failure to examine defendants’ instructions also leads to a
    misapprehension of the extent the trial court’s decision allowed for
    a fair, although imperfect, trial for both parties. The trial court used
    IPI instructions that generally, although not specifically (see Hansen
    v. Baxter Healthcare Corp., 
    309 Ill. App. 3d 869
    , 884 (1999); see
    also slip op. at 8), provided for consideration of risk-utility evidence
    by the jury. The trial court allowed defendants to argue risk utility to
    the jury. As I stated in my dissent, shortcomings within the jury
    instructions may be remedied in closing argument. See slip op. at 44
    -49-
    (Fitzgerald, C.J., concurring in part and dissenting in part) (citing
    Schultz v. Northeast Illinois Regional Commuter R.R. Corp., 
    201 Ill. 2d
    260 (2002), Carrillo v. Ford Motor Co., 
    325 Ill. App. 3d 955
    (2001), and IPI Civil (2006), at xxii (foreward to the first edition)). I
    also believe that rehearing should be granted to consider the role that
    argument to the jury could have lessened or removed any possible
    prejudice to defendant.
    Plaintiff next claims that the majority opinion departed from this
    court’s decision in Deal v. Byford, 
    127 Ill. 2d 192
    , 202-03 (1989).
    Under Deal, a party claiming error in instructions must submit “a
    correct instruction” stating the law for which he argues on appeal to
    avoid waiver. 
    Deal, 127 Ill. 2d at 202
    , citing 107 Ill. 2d R. 239(b).
    Here, defendants’ instructions were not “correct” by reason of the
    errors listed above. Left unanswered by the majority opinion is the
    role of the trial court when submitted incorrect instructions which
    would have prejudiced the opposing party. Importantly, plaintiff
    suggests that she may not have objected had the trial court given a
    neutral instruction such as:
    “When I use the expression ‘unreasonably dangerous,’ I mean
    that the risk of danger inherent in the design outweighs the
    benefits of the design when the product is put to a use that is
    reasonably foreseeable considering the nature and function of
    the product.”
    Thus, the majority decision may have been entirely different if
    defendants had additionally offered such an “integrated” instruction
    to the trial court instead of attempting to submit fatally flawed
    instructions which denied plaintiff’s theory of the case, namely,
    consumer expectation. Therefore, I believe a proper examination of
    defendants’ instructions must also include discussion of whether
    defendant properly submitted a “correct” instruction under Deal and
    what role the submission of an incorrect instruction played into the
    trial court’s exercise of discretion.2
    2
    Plaintiff makes a similar argument concerning Dillon v. Evanston
    Hospital, 
    199 Ill. 2d 483
    (2002). However, I believe the debate over that
    case was adequately set forth in my dissent.
    -50-
    Plaintiff next argues that the majority’s adoption of the
    “integrated test” ignores this court’s past precedent allowing a
    plaintiff to prove strict liability under alternate theories of liability,
    i.e., the consumer-expectation theory and the risk-utility theory. I note
    that, in general, a plaintiff is entitled to jury instructions embodying
    her theory of the case. Snelson v. Kamm, 
    204 Ill. 2d 1
    , 27-28 (2003);
    LaFever v. Kemlite Co., 
    185 Ill. 2d 380
    , 406-07, 414-15 (1998).
    Similarly, the majority held that a party has the right to have the jury
    instructed on each theory supported by the evidence and referred to
    decisions of this court over the past two decades. Slip op. at 26 (citing
    Calles v. Scripto-Tokai Corp., 
    224 Ill. 2d 247
    (2007), Hansen v.
    Baxter Healthcare Corp., 
    198 Ill. 2d 420
    (2002), and Lamkin v.
    Towner, 
    138 Ill. 2d 510
    , 529 (1990)). Here, plaintiff tendered
    consumer-expectation instructions and, since the evidence supported
    that claim, the trial court was required to instruct the jury on her
    theory.
    The majority, however, held that the trial court abused its
    discretion in giving the IPI instructions that properly set forth
    plaintiff’s theory of the case. Therefore, as the plaintiff correctly
    points out, the majority’s statement that the consumer-expectation test
    still exists as a separate theory is illusory. It also calls into question
    the holdings of Lamkin, Hansen, and Calles that a plaintiff may
    pursue her strict liability case either under the consumer-expectation
    test, the risk-utility test, or both.
    This question arises from the incorrect assumption that defendants
    had a case to prove. Defendants had no case to prove; they had a case
    to defend. If there were affirmative defenses raised by the evidence,
    defendants would have been entitled to choose whether to ask for an
    instruction on any one or all of them. Here, I believe that the general
    instructions provided by the IPI along with defense counsel’s
    argument specifically concerning risk-utility adequately provided a
    fair trial. Instead, the majority improperly erased all of the lines
    drawn in our decisions in Calles, Hansen, and Lamkin delineating a
    plaintiff’s ability to choose between the consumer-expectation test
    and the risk-utility test.
    In sum, we are left with the still unresolved question of the role
    of a trial judge when given a general IPI jury instruction on the one
    hand, and flawed jury instructions on the other. Because the majority
    -51-
    has “overlooked” the problem presented by defendants’ badly flawed
    instructions, I believe the majority has arrived at a similarly badly
    flawed solution and rehearing is required under Rule 367(b) (
    210 Ill. 2d
    R. 367(b)). The majority’s resolution of the jury instructions issue
    also leaves in doubt whether the consumer-expectation test remains
    a viable alternative and whether portions of Lamkin, Hansen, and
    Calles have been overruled. As a result, because I believe the
    majority wrongly found the trial court abused its discretion, I would
    reach the issue of remittitur. I therefore respectfully dissent upon
    denial of rehearing.
