    MEMORANDUM OPINION
    ATTREP, Chief Judge.
    {1}     Plaintiff Kathleen Oakey, personal representative of the estate of Tawana Lucero
    (the Estate), brought claims against the “Doctor on Call” business entities1 and John
    Vigil, MD (collectively, Doctor on Call), as well as a prescribing physician and a
    pharmacy, alleging that Ms. Lucero’s death was caused by excess medication
    prescribed by a physician employed by Doctor on Call. The Estate appeals the district
    court’s final judgment in favor of Doctor on Call. We affirm.
    DISCUSSION
    {2}    The Estate challenges: (1) the exclusion of an expert witness as a sanction for
    discovery violations; and (2) the grant of summary judgment on its claims for negligence
    per se, medical malpractice, negligent supervision, and vicarious liability. “[W]e review
    sanctions imposed by the trial court for discovery violations and violations of court
    orders for an abuse of discretion,” see Sanchez v. Borrego, 
    2004-NMCA-033
    , ¶ 10, 
    135 N.M. 192
    , 
    86 P.3d 617
    , and the grant of summary judgment de novo, see Lea Cnty.
    State Bank v. Markum Ranch P’ship, 
    2015-NMCA-026
    , ¶ 9, 
    344 P.3d 1089
    . The Estate,
    as the appellant, bears the burden of persuading us that the district court erred. See
    Farmers, Inc. v. Dal Mach. & Fabricating, Inc., 
    1990-NMSC-100
    , ¶ 8, 
    111 N.M. 6
    , 
    800 P.2d 1063
     (stating that a trial court’s actions are presumed to be correct and that an
    appellant “must affirmatively demonstrate” the trial court erred). We address the
    Estate’s claims of error in turn.
    I.      The District Court Did Not Abuse Its Discretion in Excluding the Estate’s
    Expert Witness as a Sanction
    {3}      On Doctor on Call’s motion, the district court excluded one of the Estate’s experts
    for its failure to timely disclose discovery related to the expert. Based on the exclusion
    of the expert, the district court eventually granted summary judgment on the Estate’s
    medical malpractice and negligent supervision claims for failure of proof. The Estate
    contends that, because Doctor on Call suffered little prejudice from the late disclosure,
    the sanction was disproportionate to the offense and, because the exclusion of the
    expert “operated to terminate [the] medical malpractice and negligent supervision claims
    in their entirety,” the district court was required to find at least willful misconduct and
    explore less drastic alternative sanctions. The Estate additionally contends that the
    district court improperly “siloed” its other expert’s testimony that was offered to fill the
    1The entities are Doctor on Call, LLC; Doctor on Call 2, LLC; Doctor on Call 3, LLC; Doctor on Call 4,
    LLC; Doctor on Call, P.C.
    gap left by the excluded expert. We discern no abuse of discretion in the district court’s
    expert witness rulings.
    {4}     The district court’s rulings were occasioned by the Estate’s failure to comply with
    an amended scheduling order extending certain pretrial deadlines (the Scheduling
    Order). The Scheduling Order came more than three years after the complaint was filed,
    after the Estate experienced multiple changes and disruptions in representation, after
    the first deadline to identify experts was extended and the second deadline expired, and
    after Doctor on Call filed a motion for summary judgment based on the Estate’s lack of
    an expert witness. New counsel then requested another extension of deadlines, which
    the district court partially granted, because, as the Estate acknowledged at the hearing
    on its request, “No expert, no case.” The district court extended the deadline for the
    Estate’s expert witness disclosure and further required the Estate to “provide any
    discovery supplementation regarding experts at the same time as the disclosure.” On
    the deadline, the Estate filed a disclosure identifying an expert who would testify
    regarding the prescribing physician’s actions and another expert who would testify as to
    Doctor on Call’s. But the Estate did not supplement discovery related to the Doctor of
    Call expert until a few weeks later (four days before the expert’s deposition)—and only
    after Doctor on Call filed a motion to strike the experts.
    {5}     The district court granted the motion in part, striking the Estate’s Doctor on Call
    expert, as a sanction for the Estate’s failure to comply with the Scheduling Order. The
    court also denied the Estate’s motion to supplement the disclosure of its remaining
    expert to include opinions about Doctor on Call. The district court judge observed that
    the extension to give the Estate “the opportunity” to have experts was “trampled” by its
    late supplementation of discovery responses in violation of the Scheduling Order. The
    district court concluded that the Estate’s production of hundreds of pages of documents
    very close in time to the expert’s deposition—even if some portion of those documents
    had been previously produced or the Estate believed them to be of little relevance—
    prejudiced Doctor on Call’s ability to prepare to question the expert. The court
    additionally concluded that the Estate offered no justification for its subsequent attempt
    to expand its other expert’s disclosure to include topics the excluded expert would have
    addressed. Given this context, we cannot say that the district court’s exclusion of the
    Doctor on Call expert and denial of the Estate’s motion to supplement the disclosure of
    the remaining expert was disproportionate to the Estate’s failure to comply with the
    Scheduling Order, see Gonzales v. N.M. Dep’t of Health, 
    2000-NMSC-029
    , ¶ 16, 
    129 N.M. 586
    , 
    11 P.3d 550
     (affirming a discovery sanction when the sanction was
    “proportional to the offenses”), or was otherwise “without logic or reason, or clearly
    unable to be defended,” see Gonzales v. Surgidev Corp., 
    1995-NMSC-047
    , ¶ 30, 
    120 N.M. 151
    , 
    899 P.2d 594
     (omission, internal quotation marks, and citation omitted).
    {6}     Nor does the ultimate consequence of the sanction—entry of summary judgment
    on the Estate’s medical malpractice and negligent supervision claims for lack of an
    expert—require a different result. A district court “may only impose the sanction
    of dismissal for failure to comply with a court order when the failure to comply is due to
    the willfulness, bad faith or fault of the disobedient party,” Gonzales, 
    1995-NMSC-047
    , ¶
    31 (emphasis, internal quotation marks, and citation omitted), and “meaningful
    alternatives must be reasonably explored before the sanction of dismissal is granted,”
    id. ¶ 33 (internal quotation marks and citation omitted). Cf. Freeman v. Fairchild, 2018-
    NMSC-023, ¶ 20, 
    416 P.3d 264
     (providing that when a sanction results in dismissal,
    courts must consider “(1) the degree of actual prejudice to the opposing party; (2) the
    amount of interference with the judicial process; and (3) the culpability of the litigant”
    (internal quotation marks and citation omitted)). Assuming that the sanction in this case
    is tantamount to dismissal—despite the more than three-year lapse in time between the
    sanction and entry of summary judgment—the record supports a determination that the
    failure to comply was willful and interfered with the judicial process, and that the district
    court explored meaningful alternatives.
    {7}     Our Supreme Court has explained that “willfulness is a conscious or intentional
    failure to comply[,] . . . is distinguished from accidental or involuntary non-compliance[,]
    and may be established even where there is no wrongful intent.” Gonzales, 1995-
    NMSC-047, ¶ 31 (internal quotation marks and citation omitted). The Estate makes no
    argument that its conduct was accidental or involuntary. Instead, the Estate
    characterizes its lack of compliance with the Scheduling Order as a “regrettable failure”
    and admits that counsel “undisputedly made . . . mistakes” that resulted in its failure to
    comply with the order. The failure at issue here was thus “conscious” and, as the district
    court noted, contrary to an explicit requirement set forth in an order that was designed
    to give the Estate an otherwise unavailable opportunity to obtain an expert. In failing to
    comply, the Estate disregarded the duties imposed by the Scheduling Order and further
    disrupted already-delayed proceedings. See 
    id.
     (permitting the sanction of dismissal
    when the failure to comply is the “fault of the disobedient party” (internal quotation
    marks and citation omitted)).
    {8}     In addition, the district court considered alternatives to exclusion. At the hearing
    on Doctor on Call’s motion to strike the Estate’s experts, the Estate suggested that
    Doctor on Call be permitted to make additional discovery requests of the expert, which
    the district court characterized as “a remedy that is not a remedy” because it “enure[d]
    to [the Estate’s] benefit” at that point. The district court also rejected Doctor on Call’s
    request to exclude both of the Estate’s experts, limiting the sanction to the single expert
    for whom there was a late document production. Further, the district court noted that
    had it “been able to find a way to fashion something less than the ultimate penalty, fees
    would have been on the table, but this is the ultimate penalty, so fees are denied.” The
    Estate identifies no particular alternative sanctions that it contends the district court
    should have considered, and in light of the record, we are satisfied that the court
    “reasonably explored” meaningful alternative sanctions. See id. ¶ 33.
    {9}    We therefore conclude that the district court did not abuse its discretion in
    excluding the Estate’s Doctor on Call expert witness or in refusing to permit the
    expansion of the remaining expert’s testimony beyond the Estate’s original disclosure.
    II.    Summary Judgment on the Estate’s Claims Was Proper
    {10} Next, we address the district court’s grant of summary judgment on the Estate’s
    claims for negligence per se, medical malpractice, negligent supervision, and vicarious
    liability.
    A.     Negligence Per Se
    {11} Doctor on Call moved for summary judgment on the Estate’s negligence per se
    claim, arguing that the regulation identified by the Estate applies to physicians and
    physician assistants, not to an entity like Doctor on Call, or, alternatively, that the
    regulation was insufficiently specific to establish a standard of care. The district court
    granted the motion on the latter ground. Because we conclude the regulation in
    question does not apply to Doctor on Call, we affirm the district court, but on different
    grounds. See Freeman, 
    2018-NMSC-023
    , ¶ 30 (“Under the right for any reason
    doctrine, an appellate court may affirm a district court ruling on a ground not relied upon
    by the district court if (1) reliance on the new ground would not be unfair to the
    appellant, and (2) there is substantial evidence to support the ground on which the
    appellate court relies.” (alterations, internal quotation marks, and citation omitted)).
    {12} To establish a claim for negligence per se, the Estate was required to
    demonstrate that the regulation in question “prescribes certain actions or defines a
    standard or conduct, either explicitly or implicitly.” Heath v. La Mariana Apartments,
    
    2008-NMSC-017
    , ¶ 7, 
    143 N.M. 657
    , 
    180 P.3d 664
     (internal quotation marks and
    citation omitted); see also Apodaca v. AAA Gas Co., 
    2003-NMCA-085
    , ¶ 45, 
    134 N.M. 77
    , 
    73 P.3d 215
     (“Legislatively authorized rules and regulations have the force of law,
    and the violation of a properly adopted and filed rule or regulation is negligence per se.”
    (alteration, internal quotation marks, and citation omitted)). The Estate argues that the
    negligence per se arose from the violation of 16.10.14.8(B) NMAC (4/3/2005), a
    regulation promulgated pursuant to the Medical Practice Act, NMSA 1978, §§ 61-6-1 to
    -34 (1989, as amended through 2023). See 16.10.14.3 NMAC (4/3/2005) (“These rules
    are promulgated pursuant to and in accordance with the Medical Practice Act.”). The
    regulations are used by the New Mexico Medical Board to determine “whether a
    physician’s or physician assistant’s prescriptive practices are consistent with the
    appropriate treatment of pain.” 16.10.14.8 NMAC (4/3/2005); see also 16.10.14.1
    NMAC (4/3/2005) (defining “board”). We conclude that Doctor on Call was not subject to
    these regulations and, consequently, any violation of them could not sufficiently
    prescribe Doctor on Call’s actions or define its standard of conduct to establish
    negligence per se. See Heath, 
    2008-NMSC-017
    , ¶ 7.
    {13} The Medical Practice Act relates to the oversight of health care practitioners,
    including physicians and physician assistants. See § 61-6-1(B), (C) (describing the Act’s
    purpose as “to protect the public from the improper, unprofessional, incompetent and
    unlawful practice of medicine,” which is effectuated by, among other things, issuing
    “licenses to qualified health care practitioners, including physicians, physician assistants
    and anesthesiologist assistants”). The applicable regulations in turn apply to “all
    physicians and physician assistants licensed by the board,” 16.10.14.2 NMAC
    (4/3/2005), and refer to “practitioners” throughout, see, e.g., 16.10.14.8(B)(1)-(5) NMAC
    (4/3/2005). Thus, the regulations relied on by the Estate apply on their face to
    practitioners, such as physicians and physician assistants, not corporate entities, like
    Doctor on Call.
    {14} The Estate nevertheless contends its negligence per se claim is viable. First, the
    Estate maintains that whether 16.10.14.8(B) NMAC (4/3/2005) applies to Doctor on Call
    is essentially immaterial—arguing that “the elements of negligence per se focus on who
    the regulations are designed to protect and not on whose conduct the regulations are
    designed to control.” This argument disregards that a claim for negligence per se has
    four prongs. See Heath, 
    2008-NMSC-017
    , ¶ 7 (applying a four-part test to determine
    whether a negligence per se instruction is appropriate: “(1) [t]here must be a statute
    which prescribes certain actions or defines a standard of conduct, either explicitly or
    implicitly, (2) the defendant must violate the statute, (3) the plaintiff must be in the class
    of persons sought to be protected by the statute, and (4) the harm or injury to the
    plaintiff must generally be of the type the [L]egislature through the statute sought to
    prevent” (internal quotation marks and citation omitted)). The Estate’s argument
    implicates two of the prongs—that the plaintiff is in the class of persons the statute is
    meant to protect and that the harm is of the type the Legislature intended to prevent.
    See 
    id.
     The Estate’s argument, however, ignores another prong—that the defendant
    violated a standard of conduct that is prescribed by the statute or regulation in question.
    See 
    id.
     If the statute or regulation does not prescribe the conduct of the particular
    defendant, the elements of negligence per se have not been satisfied. See id.;
    Apodaca, 
    2003-NMCA-085
    , ¶ 43 (concluding that the first two prongs of the negligence
    per se test are not met where the regulation in question was not applicable to the
    alleged wrongdoer). Such is the case here regarding Doctor on Call.
    {15} Next, the Estate maintains that 16.10.14.8(B) NMAC (4/3/2005) is in fact
    applicable to Doctor on Call—arguing that the regulations “are directed to ‘practitioners’”
    and that “New Mexico defines health care ‘practitioners’ . . . to include entities,”
    presumably like Doctor on Call. In support, the Estate cites authorities construing the
    Medical Malpractice Act, NMSA 1978, §§ 41-5-1 to -29 (1976, as amended through
    2023). While the Medical Malpractice Act and its construing authorities use the term
    “health care provider,” see, e.g., M.D.R. v. State ex rel. Human Services Dep’t, 1992-
    NMCA-082, ¶ 6, 
    114 N.M. 187
    , 
    836 P.2d 106
    , the regulation in question relates to the
    Medical Practice Act, not the Medical Malpractice Act. And as discussed, the Medical
    Practice Act applies to “health care practitioners,” not “health care providers.” The
    Estate’s authorities thus are unpersuasive in the context of the Medical Practice Act. In
    the present case, the Estate does not argue, nor does the evidence demonstrate, that
    Doctor on Call is a “practitioner,” as that term is used in the Medical Practice Act or
    16.10.14.8(B) NMAC (4/3/2005).
    {16} We therefore affirm the district court’s grant of summary judgment on the Estate’s
    negligence per se claim.
    B.     Medical Malpractice and Negligent Supervision
    {17} The district court granted summary judgment on the Estate’s medical malpractice
    and negligent supervision claims on the ground that these claims required expert
    testimony and, given the exclusion of Doctor on Call’s expert, the Estate had none. The
    Estate principally argues that its claims for medical malpractice and negligent
    supervision against Doctor on Call did not require expert testimony beyond that given by
    its remaining expert, who would have testified as to the prescribing physician’s standard
    of care, breach, and causation.2 Instead, the Estate argues, the jury could determine
    without expert assistance whether Doctor on Call “operated their medical business” in
    breach of the standard of care, knowingly supervised an “opioid pill mill,” and knowingly
    or negligently allowed a physician “to commit malpractice.” Specifically, the Estate
    contends that the jury could rely on (1) Doctor on Call’s failure to comply with the
    requirements in 16.10.14.8(B) NMAC (4/3/2005) and (2) their common knowledge.
    {18} As to the Estate’s first point, because, as just discussed, 16.10.14.8(B) NMAC
    (4/3/2005) does not apply to Doctor on Call by its terms, we are not persuaded that the
    jury could simply utilize that regulation as the standard of care in this case, absent an
    expert tying the licensing requirements for practitioners in that regulation to Doctor on
    Call’s duty of care as an entity or supervisor.3 See Oakey, Est. of Lucero v. May Maple
    Pharmacy, Inc., 
    2017-NMCA-054
    , ¶ 27, 
    399 P.3d 939
     (providing that “statutes,
    regulations, and/or court rules [that] apply to the conduct of a professional . . . should be
    considered in determining whether the professional fulfilled the duty imposed by the
    common law” (emphasis added)).
    {19} As to the Estate’s second point, we likewise are not persuaded that a juror’s
    common knowledge would assist them in determining what a medical entity or
    supervisor must appropriately do to meet the standard of care in relation to prescriptions
    written by employee physicians. See Richter v. Presbyterian Healthcare Servs., 2014-
    NMCA-056, ¶ 22, 
    326 P.3d 50
     (“If the act involves the use of specialized knowledge or
    2The Estate additionally makes a threshold contention that the procedures employed by the district court
    in granting summary judgment on its negligent supervision claim—i.e., permitting supplemental argument
    and surreplies—are “reason enough to reverse” the ruling. The thrust of the Estate’s contention appears
    to be that Doctor on Call never requested, nor made a prima facie case for, summary judgment on the
    negligent supervision claim in its original motion and only developed these arguments in subsequent
    pleadings. We initially question the accuracy of the Estate’s contentions in that the original motion
    requested summary judgment on “all remaining claims,” presumably encompassing negligent supervision,
    on the basis that the Estate lacked needed expert testimony. Regardless, the Estate’s argument
    disregards that the district court permitted supplemental briefing to allow the Estate an opportunity to
    address the district court’s questions about whether the claims could survive without expert testimony.
    Because the procedures granted the Estate an opportunity to offer argument to address the district
    court’s concerns, we see no basis for reversal as the Estate suggests. Lastly, to the extent the Estate
    claims in its reply brief that summary judgment was impermissible under Rule 1-056(F) NMRA, this claim
    of error comes too late. See Guest v. Berardinelli, 
    2008-NMCA-144
    , ¶ 36, 
    145 N.M. 186
    , 
    195 P.3d 353
    (“[W]e do not consider arguments raised in a reply brief for the first time.”).
    3The Estate suggests that Doctor on Call itself committed medical malpractice as a “co-prescriber”
    because its name also was on Ms. Lucero’s prescriptions and, as a result, it was a “practitioner” for
    purposes of the regulation. Because the Estate provides no authority to support its theory that an entity
    becomes a “practitioner” simply by having its name on a prescription, we do not consider this argument
    further. See In re Adoption of Doe, 
    1984-NMSC-024
    , ¶ 2, 
    100 N.M. 764
    , 
    676 P.2d 1329
     (rejecting
    arguments on the basis that they were unaccompanied by citation to legal authority).
    skill to make a judgment call as to the appropriate thing to do or not do, expert
    testimony will likely be needed to assess the resultant act or failure to act.”). The district
    court provided a reasoned explanation, supported by citation to legal authority, why
    expert testimony was needed to prove the Estate’s claims against Doctor on Call. The
    Estate baldly attacks the district court’s ruling as “unsupported” and otherwise cites
    authority unhelpful to its contention that expert testimony was not needed to prove its
    claims.
    {20} For instance, the Estate cites Richter for the general principle that “expert
    testimony will not be required if the asserted negligence is based on a standard of
    reasonable care [that] does not require professional interpretation.” Id. ¶ 28. Richter,
    however, does not shed light on whether the particular circumstances of this case would
    require “professional interpretation.” See id. ¶¶ 26-29 (determining whether expert
    testimony was required to prove the plaintiff’s claims involving the delivery of laboratory
    reports by reviewing case law with analogous factual circumstances); see also id. ¶ 24
    (providing that whether a claim can be proven without expert testimony is a fact-
    dependent inquiry). The Estate’s reliance on the uniform jury instruction for negligent
    supervision, UJI 13-1647 NMRA, likewise is not helpful. The Estate suggests the
    instruction’s third element—that “[the defendant] failed to use ordinary care in . . .
    supervising . . . [the employee],” UJI 13-1647(3)—means that an expert is never needed
    to establish the standard of care for this type of claim. This Court in Grassie v. Roswell
    Hospital Corp., 
    2011-NMCA-024
    , 
    150 N.M. 283
    , 
    258 P.3d 1075
    , considered an
    argument similar to the Estate’s—that the text of the relevant uniform jury instruction
    can be relied on to establish the type of evidence needed to prove the claim. See id.
    ¶¶ 69-71. In rejecting this argument, Grassie held that expert testimony may or may not
    be required, “depending on the circumstances of a particular case,” and that “[t]he
    essence of the claim must inform the inquiry as to the applicable standard of care.” Id.
    ¶ 71. Applying Grassie, we conclude that UJI 14-1647(3) does not alone inform our
    decision about whether an expert is needed to prove the Estate’s claims.
    {21} Put simply, in the absence of persuasive authority to support its argument that no
    expert was needed to prove its medical malpractice and negligent supervision claims
    against Doctor on Call, the Estate has not convinced us that the district court erred in
    granting summary judgment on these claims. See Farmers, Inc., 
    1990-NMSC-100
    , ¶ 8.
    C.     Vicarious Liability
    {22} The Estate also challenges the district court’s grant of summary judgment on its
    claim for vicarious liability, which sought to hold Doctor on Call liable, under a
    respondeat superior theory, based on the negligence of the prescribing physician.
    Doctor on Call, on appeal and in the district court, argued that the Estate’s settlement
    with the prescribing physician foreclosed any further claim for vicarious liability based on
    respondeat superior against Doctor on Call. The district court agreed and granted
    summary judgment on this claim. On appeal, the Estate maintains that the doctrine of
    “release the agent, release the principal” does not apply because the prescribing
    physician and Doctor on Call were joint tortfeasors, or, alternatively, other theories of
    vicarious liability, apart from respondeat superior, apply.
    {23} In support of its grant of summary judgment on the Estate’s vicarious liability
    claim, the district court cited Valdez v. R-Way, LLC, 
    2010-NMCA-068
    , 
    148 N.M. 477
    ,
    
    237 P.3d 1289
    . Valdez held that the plaintiff’s release of the employee from all claims of
    liability also released the employer from all claims of vicarious liability, because the
    “employer’s liability [arose] only by virtue of the doctrine of respondeat superior, and not
    through any independent negligence of the employer.” Id. ¶ 1. Under the reasoning in
    Valdez, any respondeat superior-based claim of liability against Doctor on Call
    dissipated once the Estate agreed to release the prescribing physician from liability on
    all claims. See id.; see generally Oakey, Est. of Lucero v. Tyson, 
    2017-NMCA-078
    ,
    ¶¶ 1, 3, 
    404 P.3d 810
     (recognizing, in an earlier appeal in this case, that the district
    court entered an order dismissing all claims against the prescribing physician with
    prejudice pursuant to a settlement agreement). That is, the Estate effectively
    “exonerate[ed]” the prescribing physician, and in so doing, “remove[d] the foundation
    upon which to impute negligence to the employer,” Doctor on Call. See Valdez, 2010-
    NMCA-068, ¶ 4 (alterations, internal quotation marks, and citation omitted).
    {24} Nevertheless, the Estate argues that Valdez excluded from its “release the agent,
    release the principal” doctrine claims against joint tortfeasors who, “through their own
    independent conduct,” caused harm. We do not disagree with this principle, see id. ¶ 1,
    but it is of no assistance to the Estate. The district court acknowledged this principle by
    limiting its ruling to the Estate’s claim for vicarious liability based on respondeat superior
    and preserving (at the time) the Estate’s claims for direct liability against Doctor on Call
    based on Doctor on Call’s own negligence. Thus, the only claim dismissed based on the
    Estate’s settlement with the prescribing physician was its claim for respondeat
    superior—the joint tortfeasor, or direct liability, claims were not dismissed.
    {25} The other bases for vicarious liability asserted by the Estate include the “specific
    safeguards” doctrine and the “peculiar risk” doctrine. As the Estate notes, however,
    these doctrines apply to independent contractors. See Valdez v. Cillessen & Son, Inc.,
    
    1987-NMSC-015
    , ¶ 18, 
    105 N.M. 575
    , 
    734 P.3d 1258
     (specific safeguards); Moulder v.
    Brown, 
    1982-NMCA-078
    , ¶ 12, 
    98 N.M. 71
    , 
    644 P.2d 1060
     (peculiar risk). The Estate
    makes no claim, and cites no evidence, that the prescribing physician was an
    independent contractor. Nor does the Estate cite any supportive authority for its
    contention that these doctrines should be applied under the facts of this case. See ITT
    Educ. Servs., Inc. v. Tax’n & Revenue Dep’t, 
    1998-NMCA-078
    , ¶ 10, 
    125 N.M. 244
    , 
    959 P.2d 969
     (providing that, where a party cites no authority for a proposition, the party’s
    argument will not be considered on appeal).
    {26} All considered, the Estate has not convinced us that the grant of summary
    judgment on its vicarious liability claim was error.
    CONCLUSION
    {27}   For the foregoing reasons, we affirm.
    {28}   IT IS SO ORDERED.
