    ORDER OF CERTIFICATION
    TO THE SUPREME COURT OF APPEALS OF WEST VIRGINIA
    KING, Circuit Judge:
    This Court, availing itself of the privilege afforded by the State of West Virginia
    through the Uniform Certification of Questions of Law Act, 
    W. Va. Code §§ 51
    -1A-1 to
    51-1A-13, hereby requests that the Supreme Court of Appeals of West Virginia exercise
    its discretion to resolve the following certified question of law:
    Whether Section 411 of the West Virginia Pattern Jury Instructions for Civil
    Cases, entitled “Design Defect — Necessity of an Alternative, Feasible
    Design,” correctly specifies the plaintiff's burden of proof for a strict liability
    design defect claim pursued under West Virginia law.
    More specifically, whether a plaintiff alleging a West Virginia strict liability
    design defect claim is required to prove the existence of an alternative,
    feasible product design — existing at the time of the subject product’s
    manufacture — in order to establish that the product was not reasonably safe
    for its intended use. And if so, whether the alternative, feasible product
    design must eliminate the risk of the harm suffered by the plaintiff, or
    whether a reduction of that risk is sufficient.
    We acknowledge that the Supreme Court of Appeals may reformulate the foregoing
    certified question. See 
    W. Va. Code §§ 51
    -1A-4, -6(a)(3). In our view, there is no
    controlling appellate decision, constitutional provision, or statute of the State of West
    Virginia that definitively answers the certified question, and the answer thereto will be
    “determinative of an issue” in this pending cause. /d. § 51-1A-3. In particular, we discern
    an absence of West Virginia authorities supportive of what we refer to herein as the
    “Section 411 Elimination Mandate” — that being Section 411’s requirement that an
    identified alternative, feasible product design “eliminate the risk of harm suffered by the
    plaintiff.”! Accordingly, we conclude that the question is appropriate for certification. To
    fully illustrate the nature of the controversy out of which the certified question arises, we
    next recite the relevant facts.
    A.
    1.
    Beginning in October 2008, plaintiff Judith Shears — a resident of Monongalia
    County, West Virginia — presented to her physician with complaints of stress urinary
    incontinence and a host of other abdominal complications. Mrs. Shears was eventually
    referred to a urogynecologist, who treated her conditions by placing a synthetic surgical
    mesh sling called “Tension-Free Vaginal Tape” (hereinafter “TVT” or the “TVT mesh”)
    beneath her urethra. Mrs. Shears’s symptoms at first abated, but in the years following the
    TVT implantation, she began experiencing renewed incontinence, urinary tract infections,
    and pelvic pain, along with urinary frequency and urgency. In October 2013, a urologist
    discovered that the TVT mesh had partially eroded into Mrs. Shears’s bladder, and an
    operation was performed to remove the eroded mesh and an attached bladder stone.
    ' The full text of Section 411 of the West Virginia Pattern Jury Instructions is set
    forth, in haec verba, infra at pages 6 and 13.
    3
    Additional eroded mesh was discovered in Mrs. Shears’s bladder in 2014, and she has since
    experienced recurrent bladder stones and severe associated bladder and urinary difficulties.
    Along with her husband Gary Shears, Mrs. Shears initiated this civil action in July
    2013 against Ethicon, Inc. — the manufacturer and seller of the TVT mesh — and its parent
    company, Johnson & Johnson.” The Shearses filed their lawsuit in the Southern District
    of West Virginia as part of a multidistrict litigation captioned Jn re: Ethicon, Inc., Pelvic
    Repair System Products Liability Litigation, No. 2:12-md-02327 (the “MDL”), which was
    assigned by the federal judicial system’s Judicial Panel on Multidistrict Litigation to the
    Honorable Joseph R. Goodwin.? Contending that the TVT’s erosion was to blame for Mrs.
    Shears’s injuries, the Shearses pursued numerous claims for relief, including — as relevant
    to this appeal —a strict product liability claim alleging a design defect in the TVT, as well
    as a claim for negligent design thereof. Mr. Shears, for his part, joined in the lawsuit by
    suing for loss of consortium.
    In June 2015, the MDL court consolidated 37 of the West Virginia-based actions
    pending against Ethicon in the MDL — including the Shearses’ — for trial on the issue of
    the TVT’s purported defective design. Ethicon objected to the MDL court’s West Virginia
    consolidation, contending in pertinent part that, pursuant to West Virginia law, product
    2 We refer to defendants Ethicon and Johnson & Johnson collectively as “Ethicon.”
    3 The Shearses’ lawsuit was filed as part of the specific Ethicon MDL, which
    comprised nearly 28,000 cases filed against Ethicon relating to the company’s TVT mesh.
    Six other pelvic mesh-related product liability MDLs were also assigned to Judge
    Goodwin, and at the time of the proceedings described herein, the seven MDLs together
    encompassed some 58,000 cases.
    liability plaintiffs alleging a design defect are obliged to identify a “safer alternative
    design” which “would have materially reduced the plaintiff's injuries.” See Mullins v.
    Ethicon, Inc., No. 2:12-cv-02952, at 3 (S.D.W. Va. July 1, 2015), ECF No. 27 (emphasis
    added). More specifically, Ethicon asserted that proving a defective design requires
    “plaintiff-specific evidence” — thereby rendering any consolidated trial inappropriate. Jd.
    In an August 2015 order clarifying the scope of the consolidated trial, the MDL
    court overruled Ethicon’s objections, principally explaining that the Supreme Court of
    Appeals of West Virginia “has not stated one way or the other whether a design defect
    claim requires proof of a safer alternative design of the allegedly defective product.” See
    Mullins v. Ethicon, Inc., No. 2:12-cv-02952, at 17 (S.D.W. Va. Aug. 4, 2015), ECF No. 38
    (the “Clarification Ruling”) (quoting Keffer v. Wyeth, 
    791 F. Supp. 2d 539
    , 547-48 (S.D.W.
    Va. 2011)).4 The MDL court acknowledged that “evidence on the existence of a safer
    alternative is certainly relevant” to “determining whether a product is ‘unsafe’,” but its
    Clarification Ruling resolved that “there is no West Virginia authority requiring plaintiffs
    to prove, as part of their prima facie case, that [a] proposed safer alternative design would
    have reduced an individual plaintiff's specific injuries.” Jd.
    2.
    In June 2016, as discovery proceedings were yet ongoing in the MDL court, the
    Supreme Court of Appeals of West Virginia published its West Virginia Pattern Jury
    4 The Clarification Ruling is published and can be found at 
    117 F. Supp. 3d 810
    (S.D.W. Va. 2015).
    Instructions for Civil Cases (hereinafter the “PJI”). The PJI are a set of jury instructions
    made commercially available by the West Virginia high court, and their drafting and
    assembly were overseen by Justice Ketchum and Fourtcenth Judicial Circuit Judge Alsop.
    The Preface to the PJI explains that the instructions “were written to help trial judges and
    lawyers instruct the jury in a civil case.” See J.A. 68.5 The Preface also makes clear,
    however, that the instructions are “not binding,” and specifies that “lawyers have an
    obligation to object and point out any errors in any pattern instruction.” /d.
    Especially relevant to these proceedings, Section 400 of the PJI sets forth pattern
    jury instructions for various product liability claims. Contained within Section 400 is
    Section 411, an instruction entitled “Design Defect — Necessity of an Alternative, Feasible
    Design.” See J.A. 69. Section 411 provides as follows:
    There are many designs which, although they may eliminate a particular risk,
    are not practicable to produce. To prove that a design is defective, [name of
    plaintiff] must prove that there was an alternative, feasible design that
    eliminated the risk that injured [him/her].
    
    Id.
    Just weeks after the publication of the PJI, Ethicon used that development to seck
    reconsideration of the MDL court’s Clarification Ruling. In its motion, Ethicon maintained
    that Section 411’s requirement for a design defect plaintiff to prove an alternative, feasible
    product design that would eliminate the risk of harm to the plaintiff revealed error in the
    MDL court’s earlier characterization of the applicable burden of proof. Importantly,
    > Citations herein to “J.A. _” refer to the contents of the Joint Appendix filed in
    this Court by the parties to this appeal.
    Ethicon insisted that Section 411 did not reflect a new pronouncement of West Virginia
    law, but was instead rooted in extant authority from the Supreme Court of Appeals, given
    that the Section’s “Notes and Sources” provision referenced two decisions from the West
    Virginia high court — Morningstar v. Black & Decker Manufacturing Co., 
    253 S.E.2d 666
    (W. Va. 1979), and Church v. Wesson, 
    385 S.E.2d 393
     (W. Va. 1989). See J.A. 69.°
    By an unpublished order of December 2016, the MDL court granted Ethicon’s
    reconsideration motion, explaining that — in light of Section 411 of the PJI — its
    “inescapable conclusion” was that “in a West Virginia strict liability design defect products
    liability case, a plaintiff must prove that there was an alternative, feasible design — existing
    at the time of the product’s manufacture — that would have eliminated the risk that injured
    the plaintiff.” See Mullins v. Ethicon, Inc., No. 2:12-cv-02952, at 11 (S.D.W. Va. Dec. 9,
    2016), ECF No. 1525 (the “Reconsideration Ruling”). In its Reconsideration Ruling, the
    court recognized that “the PJI [are] optional and not binding on courts,” making note that
    the PJI’s Preface “emphatically state[s]” that the instructions “ARE NOT BINDING ON
    © We observe that, as an alternative to its request for the MDL court to reconsider
    its Clarification Ruling, Ethicon sought to have the following question certified by the
    MDL court to the Supreme Court of Appeals of West Virginia:
    In order to prove that a design is defective in a product liability case, does
    West Virginia law require the plaintiff to prove that there was an alternative,
    feasible design that eliminated the risk that injured him or her?
    See J.A. 62. The MDL court ultimately denied Ethicon’s alternative motion to certify as
    moot after granting the reconsideration motion. As explained herein, however, we now
    resolve that certification is the appropriate course for determining whether Section 411 is
    a complete and accurate statement of West Virginia law.

    THE TRIAL JUDGE” and that “[o]n appeal, the Supreme Court is not bound by the
    correctness of these pattern instructions.” /d. at 5. Nevertheless, the Reconsideration
    Ruling went on to resolve that the PJI “have gone through multiple edits and revisions after
    extensive research and editing by the reporters, the review committees, Judge Alsop, and
    Justice Ketchum,” and that, at the end of the day, the instructions were “backed by the
    blessing of the West Virginia Supreme Court.” Jd. at 5-6. After taking stock of Section
    411’s reliance on the Supreme Court of Appeals’ Morningstar and Church decisions, the
    MDL court rested on “the persuasive force behind the PJI in helping me predict how the
    West Virginia Supreme Court would rule on this issue,” concluding that Section 411
    supplies the correct burden of proof for a strict liability design defect claim pursued under
    West Virginia law. Jd. at 6.’

    In November 2020, following the entry of the MDL court’s Reconsideration Ruling,
    the close of discovery in the consolidated West Virginia cases, and summary judgment
    7 As the Shearses note in their opening appellate brief, a supplemented version of
    the PJI was published in 2017, and — although the text of Section 41] remained unchanged
    therein — the Section’s “Notes and Sources” provision was updated to include a citation
    to the MDL court’s 2016 Reconsideration Ruling. See Br. of Appellants 21 n.4, That
    alteration does not resolve our uncertainty as to whether Section 411 provides a correct
    statement of West Virginia law. On the one hand, the Reconsideration Ruling is an
    unpublished decision rendered by a federal court — not a binding pronouncement of state
    law handed down by an arm of the West Virginia judiciary. And that matter aside, the
    Reconsideration Ruling is not some pre-existing edict that Section 411 can purport to be
    grounded in. It was instead rendered subsequent to Section 411’s formulation, accepting
    the “persuasive force behind” the Section’s characterization of design defect claims.
    8
    dispositions having been made as to several of the individual West Virginia plaintiffs, the
    MDL court entered a transfer order and ruled that, of the 79 cases remaining in the full
    Ethicon MDL, nine of those cases — including the Shearses’ — “would be more
    expeditiously concluded in the venues from which they arise.” See In re: Ethicon, Inc.,
    Pelvic Repair Sys. Prods. Liab. Litig., No. 2:12-md-02327, at 1 (S.D.W. Va. Nov. 20,
    2020), ECF No. 9186. In its transfer order, the court urged that, given the “[e]xtensive
    development of these cases over a period of years,” the receiving district courts should
    “immediately set the[] cases for trial without reopening discovery.” Jd. at 1-2. On
    December 4, 2020, the Shearses’ case was officially transferred to the Northern District of
    West Virginia (hereinafter the “trial court”). See Shears v. Ethicon, Inc., No. 1:20-cv-
    00264 (N.D.W. Va. Dec. 4, 2020), ECF No. 29.
    Ata hearing conducted on February 11, 2022, the trial court took up several pending
    Daubert motions regarding expert witnesses for both the Shearses and Ethicon.® One of
    Ethicon’s Daubert motions sought to limit the testimony of Dr. Uwe Klinge, the Shearses’
    design and materials expert. Dr. Klinge’s expert report spoke to two possible alternatives
    to the design of Ethicon’s TVT mesh — specifically, polyvinylidene fluoride and
    “Ultrapro.” See J.A. 3011. Dr. Klinge expressed that, in his professional opinion, those
    materials posed a far lower risk of erosion in pelvic tissue than the TVT mesh and
    8 The Supreme Court’s decision in Daubert v. Merrell Dow Pharmaceuticals, Inc.,
    
    509 U.S. 579
     (1993), established the standard for the admissibility of expert testimony
    under Federal Rule of Evidence 702. Broadly, Daubert requires a district court to “ensur[e]
    that an expert’s testimony both rests on a reliable foundation and is relevant to the task at
    hand.” See 
    509 U.S. at 597
    .
    represented “safer alternative mesh material[s] for treatment of stress urinary incontinence
    than Ethicon’s TVT Prolene mesh.” /d. at 3014.2 In other words, Dr. Klinge did identify
    alternative mesh designs — evidently in keeping with the demands of Section 411 of the
    PJI — but his expert report framed and qualified those designs as simply reducing the risk
    of harm that would stem from the product, thereby falling short of the Section 411
    Elimination Mandate. Seizing on that distinction, Ethicon asserted that Dr. Klinge’s
    testimony was inadmissible.
    The trial court questioned the Shearses’ lawyer regarding the Section 411
    Elimination Mandate from the outset of the Daubert hearing, noting its concern “about the
    requirement under West Virginia products liability law, as found by Judge Goodwin and
    as established by the pattern jury instructions, that the alternative feasible design must
    eliminate the risk of which the plaintiff complains that caused the injuries.” See J.A. 5464.
    Accepting the legal soundness of Section 411’s requirements as the MDL court had, the
    trial court explained that, in Dr. Klinge’s expert report, it “saw fulsome discussions about
    this is better, this is safer, but [Dr. Klinge] . . . never said [the alternative mesh designs]
    eliminated the risk but rather reduced the risk.” Jd. at 5465. Ultimately, because Dr.
    Klinge’s expert testimony would not have aided the Shearses in satisfying the Section 411
    Elimination Mandate — that is, because his testimony simply “does not meet the standard
    under West Virginia law” — the court granted Ethicon’s Daubert motion and barred Dr.
    Klinge from testifying about his proffered alternative mesh designs. /d. at 5569-70.
    ° “Prolene” is one of several brand names used by Ethicon to market the TVT mesh.

    2.
    The Shearses proceeded to a seven-day jury trial against Ethicon in Clarksburg in
    March 2022, continuing to press their strict liability design defect claim as well as their
    claim alleging negligent design of the TVT mesh. Recognizing, however, that the trial
    court’s restraint of Dr. Klinge’s testimony essentially foreclosed their ability to establish a
    defective product design under the standard of Section 411, the Shearses pursued their
    design defect claim under an alternative, so-called “malfunction theory” of liability.
    Under West Virginia law, the malfunction theory permits success on a strict product
    liability claim using only circumstantial evidence, so long as the plaintiff “shows that a
    malfunction in the product occurred that would not ordinarily happen in the absence of a
    defect.” See Anderson v. Chrysler Corp., 
    403 S.E.2d 189
    , 194 (W. Va. 1991). The trial
    court promptly ended the Shearses’ reliance on the malfunction theory, however, granting
    Ethicon’s motion for judgment as a matter of law on the design defect claim at the close of
    the Shearses’ case-in-chief. The court ruled that, because the Shearses’ experts had
    conceded in their testimony that erosion is a known risk of any pelvic surgery involving an
    artificial mesh implant like TVT, no reasonable jury could conclude that the mesh erosion
    experienced by Mrs. Shears was a “malfunction” that would not have occurred but for some
    unexpected flaw in the mesh’s design. Following the presentation of Ethicon’s evidence,
    the court instructed the jury on the Shearses’ sole remaining negligent design claim, and
    the jury returned a verdict for Ethicon on that claim later the same day.
    The Shearses timely noticed this appeal on April 12, 2022, and we possess
    jurisdiction pursuant to 
    28 U.S.C. § 1291
    .
    11
    II.
    A.
    In their appeal to this Court, the Shearses primarily challenge the trial court’s (and,
    by extension, the MDL court’s) embrace of Section 411 of the PJI, insisting that Section
    411’s framing of the standard of proof for a strict liability design defect claim is fatally
    flawed, lacking any support in controlling West Virginia law. The Shearses take particular
    issue with the Section 411 Elimination Mandate, asserting that the trial court erroneously
    restricted Dr. Klinge’s expert testimony because of his inability to meet that high bar.
    Separately, the Shearses contest the trial court’s ruling on the “malfunction theory” of
    liability and its ensuing award of judgment to Ethicon on the design defect claim, as well
    the court’s formulation of the jury instruction regarding the negligent design claim.
    As explained below, we are satisfied that “there is no controlling appellate decision,
    Constitutional provision or statute” of the State of West Virginia that resolves the question
    of whether Section 411 sets forth a correct statement of law — nor is there sufficient
    authority that would permit us to reasonably guess how the Supreme Court of Appeals of
    West Virginia might resolve that question. See 
    W. Va. Code § 51
    -1A-3. The precedent
    that Ethicon relies on in defending Section 411 — that being the West Virginia high court’s
    rulings in Morningstar and Church, and this Court’s 2017 Nease v. Ford Motor Co.
    decision — simply does not carry the day. In so concluding, we are mindful that the parties
    to this appeal have not requested that any questions be certified to the Supreme Court of
    Appeals. Indeed, the parties agreed at oral argument that certification is not necessary,
    albeit only because each side is now assured that West Virginia law tips in their favor.
    12
    Nevertheless, a decision to certify an issue to a state high court “rests in the sound
    discretion of the federal court,” see Lehman Bros. v. Schein, 
    416 U.S. 386
    , 390-91 (1974),
    and we are entitled to sua sponte certify a state law question, see Elkins v. Moreno, 
    435 U.S. 647
    , 662 (1978).
    Considering the sparsity of governing state law, we hereby certify the issue of
    Section 411’s validity to the Supreme Court of Appeals, confident that the Court’s answer
    — if it elects to furnish one — will “be determinative of an issue in [this] pending cause.”
    See 
    W. Va. Code § 51
    -1A-3.'° We are of opinion that, once that certified question is
    resolved, existing West Virginia authority will provide us with adequate guidance to
    resolve the Shearses’ remaining appellate contentions.
    B.
    Once more, Section 411 of the PJI — as published in 2016 by the Supreme Court
    of Appeals of West Virginia — provides as follows:
    There are many designs which, although they may eliminate a particular risk,
    are not practicable to produce. To prove that a design is defective, [name of
    plaintiff] must prove that there was an alternative, feasible design that
    eliminated the risk that injured [him/her].
    10 We are confident that resolving the certified question will enable the Supreme
    Court of Appeals to reach the correct result as to the legal propriety of Section 411, That
    Section — and the balance of the PJI — was apparently adopted by a committee of
    reviewers and reporters, under the auspices of Justice Ketchum and Judge Alsop. By
    accepting the certified question and engaging skilled lawyers in adversary proceedings that
    include briefing and argument of the competing views, the Court will fully test the legal
    weight and import of the PJI in the context of an ongoing active controversy.
    13
    See J.A. 69. To be perfectly clear, we readily agree with the MDL court that the PJI should
    carry substantial weight in ascertaining the correct burden of proof that a plaintiff must
    bear in proving a claim pursued under West Virginia law. The PJI are owned and published
    by — indeed “backed by the blessing of”? — the Supreme Court of Appeals, and by all
    accounts “have gone through multiple edits and revisions after extensive research and
    editing.” See Reconsideration Ruling 5-6. They may even constitute a “recent
    pronouncement{] of general rules or policies by [a] state’s highest court,” which, under this
    Court’s precedent, may be used in predicting a decision of a state high court in a diversity
    matter such as this one. See Liberty Mut. Ins. Co. v. Triangle Indus., Inc., 
    957 F.2d 1153
    ,
    1156 (4th Cir. 1992).
    Yet the PJI go out of their way to stress that they do not directly carry the force and
    effect of law — they are “not binding” on either trial or appellate courts in West Virginia,
    and they invite “lawyers .. . to object and point out any errors in any pattern instruction
    that is offered by a party or which a trial judge indicates will be read to the jury.” See J.A.
    68. And as the Shearses have aptly explained in their objections to Section 411 of the PJI,
    no portion of that Section’s recitation of the standard of proof for a strict liability design
    defect claim finds direct support in controlling West Virginia law. That is especially so
    with respect to the Section 411 Elimination Mandate. Thus, wedged between the
    “persuasive force” of the PJI and the scarcity of West Virginia legal authorities backing
    Section 411’s framing, we find ourselves unable to determine whether the trial court rightly
    relied on Section 411 in limiting the testimony of the Shearses’ expert witness. That being
    so, we respectfully request the considered advisement of the Supreme Court of Appeals.
    14
    1.
    For background, in Morningstar v. Black & Decker Manufacturing Co. — the
    Supreme Court of Appeals’ seminal decision regarding strict product liability claims —
    the Court recognized that a “defective product” “may fall into three broad, and not
    necessarily mutually exclusive, categories: design defectiveness; structural defectiveness;
    and use defectiveness.” See 
    253 S.E.2d 666
    , 682 (W. Va. 1979). Morningstar established
    a “general test” for ““defectiveness” that looks to “whether the involved product . . . is not
    reasonably safe for its intended use.” /d. at 683. Once a plaintiff demonstrates that “the
    product was defective when it left the manufacturer and that the defect proximately caused
    the plaintiff's injury” while the product was being used in “a reasonably intended manner,”
    “a recovery is warranted.” /d. at 680, 682.
    Elaborating on its “defectiveness” and “reasonable safety” standard, the 1979
    Morningstar decision goes on to state that
    [t]he standard of reasonable safeness is determined not by the particular
    manufacturer, but by what a reasonably prudent manufacturer’s standards
    should have been at the time the product was made. ... The term “unsafe”
    imparts a standard that the product is to be tested by what the reasonably
    prudent manufacturer would accomplish in regard to the safety of the
    product, having in mind the general state of the art of the manufacturing
    process, including design, labels and warnings, as it relates to economic
    costs, at the time the product was made.
    See 
    253 S.E.2d at 682-83
    . The foregoing language reflects West Virginia’s formulation of
    the so-called “risk-utility test,” under which product defectiveness may be determined by
    balancing a given product’s risk of causing harm against the costs of reducing that risk. /d.
    15
    at 682 (“We believe that a risk/utility analysis does have a place in a tort product liability
    case.”’).
    Doubtlessly, the Supreme Court of Appeals has offered some measure of support
    for Section 411’s preliminary requirement that a strict liability design defect plaintiff is
    obliged to establish the existence of an “alternative, feasible design.” Morningstar’s
    construction of the risk-utility test looks in part to the “reasonably prudent manufacturer’s”
    consideration of “the general state of the art of the manufacturing process, including
    design.” See 
    253 S.E.2d at 682-83
    . And Morningstar also explained that expert testimony
    bearing on the risk-utility analysis will aid a jury in “evaluat[ing] the complex technical
    problems relating to product failure, safety devices, [and] design alternatives.” Id, at 682.
    Other courts applying West Virginia law, meanwhile, have resolved that proof of a “safer
    alternative” may serve as “at least one method of showing that a product is ‘not reasonably
    safe for its intended use.’” See Keffer v. Wyeth, 
    791 F. Supp. 2d 539
    , 547-48 (S.D.W. Va.
    2011) (emphasis added); see also Clarification Ruling 17 (“[WJhether required or not,
    evidence on the existence of a safer alternative is certainly relevant.”). It is of importance
    to us, however, that at no point has the Supreme Court of Appeals definitively stated — in
    a signed, published opinion — “one way or the other whether a design defect claim requires
    proof of a safer alternative design of the allegedly defective product.” See Keffer, 
    791 F. Supp. 2d at 547
     (emphasis added) (recognizing lack of guiding decisional law).
    At least one post-Morningstar decision of the Supreme Court of Appeals is
    apparently supportive of the proposition that a plaintiff must identify an alternative product
    design to prevail on a design defect claim. In Church v. Wesson — a 1989 ruling referred
    16
    to alongside Morningstar in Section 411’s “Notes and Sources” provision — the Court
    affirmed a directed verdict in favor of a defendant-manufacturer because the design defect
    plaintiff had failed to cstablish the existence of an alternative, feasible design for a “roof
    bolt wrench” that had injured him — such that the plaintiff “failed to establish a prima
    facie right of recovery.” See 
    385 S.E.2d 393
    , 396 (W. Va. 1989). The Church decision
    specifically concluded that the plaintiff's proposed “forging”-based alternative design of
    the bolt wrench was “not feasible when the fractured wrench was manufactured,” and that
    the plaintiff's evidence failed for that reason alone. /d. The Court did not resolve, however,
    that proof of an alternative, feasible wrench design was the only means available to the
    plaintiff for establishing a defective design, or that no other form of evidence could have
    advanced his claim to the jury — only that the plaintiff's chosen evidence was deficient. '!
    In defending Section 411’s alternative design requirement, Ethicon also relies
    heavily on this Court’s 2017 decision in Nease v. Ford Motor Co., 
    848 F.3d 219
     (4th Cir.
    2017). Therein, defendant Ford Motor — seeking to fend off a West Virginia strict liability
    design defect claim — argued that Morningstar actually articulated a requirement “to prove
    '! On appeal, the Shearses emphasize the limited nature of Church’s reasoning, and
    take issue with Section 41 1’s reliance thereon because Church is designated as a per curiam
    opinion. Church is not a signed opinion that — as the Supreme Court of Appeals has
    emphasized — carries greater weight than a per curiam ruling. In its 2001 Walker v. Doe
    decision, the Court explained that it “will use signed opinions when new points of law are
    announced and those points will be articulated through syllabus points.” See 
    558 S.E.2d 290
    , 296 (2001); accord State v. McKinley, 
    764 S.E.2d 303
    , 313 (2014). Per curiam
    opinions, the Court emphasized, apply “settled principles of law to facts necessarily
    differing from those at issue in signed opinions.” See Walker, 558 S.E.2d at 296. The
    Church decision therefore brings nothing to the table that Morningstar did not already
    decide.
    17
    that a reasonably prudent manufacturer would have adopted a safer design during the
    relevant time period.” /d. at 234. Plaintiff Nease countered that the Supreme Court of
    Appeals has never enforced such a rule, and our decision acknowledged that “West
    Virginia law on the matter is not crystal clear.” Jd. Nevertheless, we agreed with Ford
    Motor “that Morningstar can only be read to require the production of evidence on
    reasonable alternative design, to gauge what ‘should have been.’” /d. (quoting
    Morningstar, 
    253 S.E.2d at 683
    ). More specifically, Nease resolved that, “(a]lthough
    Morningstar does not use the phrase ‘alternative design,” a plaintiff in a design case, for
    all practical purposes, must identify an alternative design in order to establish the state of
    the art.” Jd.
    Ethicon contends in this appeal that, after Nease’s endorsement of the “alternative
    design” standard, there is no open question whether Section 411’s inclusion of that
    requirement is faithful to West Virginia tort law. And while it is certainly true that we
    must abide by our own prior decisions, a ruling by this Court cannot and does not propound
    new principles of state law. To be sure, if the Supreme Court of Appeals arrived at a
    conclusion contrary to Nease, that determination would control. See Passaro v. Virginia,
    
    935 F.3d 243
    , 252-53 (4th Cir. 2019). While our Nease decision would likely prove
    sufficient to resolve this matter were the only question before us whether proof of an
    alternative, feasible product design is requisite to a successful design defect claim, we are
    presently faced with a significantly broader inquiry — whether the whole of Section 411
    spells out the correct burden of proof. And as described further below, neither Church nor
    Nease have settled that issue. At bottom, while the preliminary portion of Section 411 does
    18
    find some degree of footing in West Virginia decisional law (and in the precedent of this
    Court), there is simply no decision of the Supreme Court of Appeals that has squarely
    resolved whether proof of an alternative, feasible design is an essential element of a design
    defect claim, or whether other sorts of evidence can demonstrate — with equal force —
    that a product is “not reasonably safe for its intended use.”
    2.
    After reciting that proof of an “alternative, feasible design” is imperative for
    establishing a defective product design, Section 411 goes on to lay out its most important
    aspect in the context of this proceeding — that is, the Section 411 Elimination Mandate.
    That requirement specifies that such an alternative design must completely “eliminate[] the
    risk that injured” the plaintiff. And it was on that basis that the trial court limited the
    testimony of Dr. Klinge, insofar as his expert report spoke only to alternative pelvic mesh
    12 As the MDL court observed in its Reconsideration Ruling, Sections 409 and 410
    of the PJI also speak to strict liability design defect claims, with the former laying out the
    general elements of a design defect claim as articulated by Morningstar, and the latter
    describing Morningstar’s risk-utility test. Section 410, for its part, provides that “[t]o
    determine whether a design was defective,” the jury is to “decide if the benefits of the
    design outweigh the risks,” considering, inter alia, the “feasibility of an alternative, safer
    design”; the “cost of an alternative design”; any “disadvantages of an alternative design”;
    and “other relevant factors.” See Reconsideration Ruling 9.
    The MDL court evidently accepted Section 410’s inclusion of “alternative, safer
    designs” in its presentation of the risk-utility test as validating Section 411’s requirement
    of an alternative, feasible design to prove a defective design. But Section 410 relies
    exclusively on Morningstar for authority in its “Notes and Sources” provision. And as
    explained above, Morningstar sets forth no such explicit condition. Moreover, Section
    410’s incorporation of “other relevant factors” into the risk-utility test begs the question of
    whether Section 411 wrongly cabins the “defectiveness” inquiry to the existence of an
    alternative product design.
    19
    designs that would have lessened the risk of mesh erosion. Although Section 411’s first
    requirement of an alternative product design can — as now explained — claim at least
    some basis in West Virginia law, the Section 411 Elimination Mandate appears to lack a
    similar legal foundation.
    As previously mentioned, the first published version of Section 411 relied on two
    putatively authoritative decisions of the Supreme Court of Appeals in its “Notes and
    Sources” provision — Morningstar and Church. But neither of those decisions actually
    discuss the “elimination” of a product’s risk of danger or any analogue to the same effect.
    Morningstar, for its part, discusses only — and quite generally — the role of product design
    in a “defectiveness” inquiry. It never considered the extent to which a potential or alternate
    product design might shift the end result’s likelihood of causing harm. 13 And the Church
    decision — as we heretofore emphasized — was centered around the infeasibility of the
    plaintiff's proffered alternative product design. Given the plaintiff's failure to put forth an
    adequate alternative, the Court in Church had no reason to speculate as to what impact the
    alternative may have had on the odds of the plaintiff suffering an injury.
    '3 At oral argument, Ethicon’s lawyer pointed out that a footnote in the Morningstar
    decision contemplates “[t]he manufacturer’s ability to eliminate the unsafe character of the
    product without impairing its usefulness.” See 
    253 S.E.2d at
    681 n.20. That footnote,
    however, was used only to spell out an alternative formulation of the risk-utility test
    (included in a broad survey of other jurisdictions’ standards for defining a product
    “defect”), which the Supreme Court of Appeals did not adopt in Morningstar.
    20
    In this appeal, Ethicon turns again to our Nease decision to contend that the Section
    411 Elimination Mandate is legally sound.'* But Nease does no more to bolster that
    requirement than do the Morningstar and Church decisions. For starters, we again
    emphasize that our rulings about West Virginia law do not constitute controlling
    pronouncements thereof. And even if they did, the parties’ dispute in Nease was whether
    Morningstar “requires a product liability plaintiff to prove that a reasonably prudent
    manufacturer would have adopted a safer design during the relevant time period” — not
    whether some other product design would have wiped out all risk of harm flowing from
    the product. See 
    848 F.3d at 233
     (emphasis added). Ultimately, after concluding that
    Morningstar does call for proof of an alternative product design, Nease resolved that the
    plaintiff's expert testimony regarding alternative designs should have been excluded from
    the trial evidence, as it was not supported by adequate testing data. In so ruling, we
    observed that the plaintiff's expert “offered no data ... to prove that the [alternative]
    designs were /ess likely to [fail] than the one” that had injured the plaintiff, in effect
    suggesting that alternative designs need only diminish a product’s chances of generating
    harm. /d. at 234 (emphasis added).
    14 The Shearses’ appellate briefing advises us that the 2017 revised edition of the
    PJI added a citation to Nease within Section 411’s “Notes and Sources” provision,
    alongside the previously mentioned citation to the MDL court’s Reconsideration Ruling.
    See supra note 7. As explained herein, however, Nease does not provide any direct support
    for Section 411’s characterization of a design defect plaintiff’s burden of proof. Indeed,
    neither Section 411 nor the rest of the PJI were considered or discussed in Nease.
    21
    In short, we have identified no West Virginia precedent that ratifies the Section 411
    Elimination Mandate. To the extent that evidence of an alternative, feasible product design
    is necessary to prevail on a design defect claim — or is otherwise supplied by a plaintiff,
    even if not required — it could be the case that the alternative design’s reduction of the
    risk of harm (as Dr. Klinge discussed in his expert report) suffices to establish that the
    subject product was “not reasonably safe for its intended use.” See, e.g., Willet v. Johnson
    & Johnson, 
    465 F. Supp. 3d 895
    , 905 (S.D. Iowa 2020) (ruling — in an Ethicon pelvic
    mesh lawsuit remanded from the MDL court in 2019 — that under Iowa law, design defect
    claims require “expert testimony [that] establish[es] a reasonable alternative design and the
    ability of such design to reduce the foreseeable harm of the challenged product”). Because
    there is no West Virginia authority resolving that uncertainty — or suggesting one direction
    over the other — we lack any sound bases for predicting whether the Supreme Court of
    Appeals would sanction the Section 41] Elimination Mandate.
    *k* +
    Given the shortage of instructive precedent, we are satisfied that “the available state
    law is clearly insufficient” to determine whether the Supreme Court of Appeals of West
    Virginia would conclude that Section 411 of the PJI — and, most notably, the Section 411
    Elimination Mandate — correctly states the plaintiff's burden of proof for a strict liability
    design defect claim. See Roe v. Doe, 
    28 F.3d 404
    , 407 (4th Cir. 1994). For the same
    reason, we are unable to resolve whether the trial court correctly limited the scope of the
    Shearses’ expert testimony. To be certain, the PJI — potentially an encapsulation of the
    Supreme Court of Appeals’ understanding of numerous areas of state law — present a
    22
    thorough definition of a design defect claim. When consulted to confirm the PJI’s
    accuracy, however, West Virginia decisional law is largely silent. In these circumstances,
    we are constrained to seek the sound guidance of the Supreme Court of Appeals.
    Il.
    In light of the foregoing, we again identify the controlling question of West Virginia
    law to be this:
    Whether Section 411 of the West Virginia Pattern Jury Instructions for Civil
    Cases, entitled “Design Defect — Necessity of an Alternative, Feasible
    Design,” correctly specifies the plaintiff’s burden of proof for a strict liability
    design defect claim pursued under West Virginia law.
    More specifically, whether a plaintiff alleging a West Virginia strict liability
    design defect claim is required to prove the existence of an alternative,
    feasible product design — existing at the time of the subject product’s
    manufacture — in order to establish that the product was not reasonably safe
    for its intended use. And if so, whether the alternative, feasible product
    design must eliminate the risk of the harm suffered by the plaintiff, or
    whether a reduction of that risk is sufficient.
    And we emphasize that the Supreme Court of Appeals of West Virginia may reformulate
    the certified question at its discretion. All of the parties in this matter are represented by
