¶ 1 Cicly Patricia Youtsey Jamerson appeals the superior court’s dismissal of her negligence claim against Robert Quintero and American Floor. We hold that by statute, when a principal is jointly and severally liable for the fault of its agent, a stipulated dismissal with prejudice of the principal does not as a matter of law bar a claim against the agent. Accordingly, we vacate the judgment against Jamerson and remand.
FACTS AND PROCEDURAL BACKGROUND
¶ 2 Jamerson allegedly slipped and fell in water a janitor left on the floor of a Coolidge drugstore. She sued the janitor, Quintero, and his employer, American Floor (collectively, “American”), alleging negligence. Her complaint also included a claim against the owner of the store, Walgreen Arizona Drag Co., alleging it had breached its non-delega-ble duty to keep the premises safe.
¶ 3 After mediation, Jamerson settled her claim against Walgreen, and the superior court entered a stipulated order dismissing Walgreen with prejudice. American then moved for summary judgment, arguing the dismissal of the claim against Walgreen constituted an adjudication on the merits that exonerated American. Citing De Graff v. Smith,
¶ 4 The superior court granted American’s motion “[f]or the reasons stated by [American].” We have jurisdiction of Jamerson’s timely appeal pursuant to Article 6, Section 9, of the Arizona Constitution, and Arizona Revised Statutes (“AR.S.”) sections 12-120.21(A)(1) (2013) and — 2101(A)(1) (2013).
DISCUSSION
¶ 5 As American acknowledges, Walgreen has a non-delegable duty to keep its premises safe for its invitees. Accordingly, Walgreen is vicariously liable for any negligence of American, the independent contractor it hired to clean its store. See, e.g., Wiggs v. City of Phoenix,
¶ 6 When a plaintiff sues both the agent and the principal for the negligence of the agent, a judgment in favor of the agent bars the plaintiffs vicarious liability claim against the principal, even when the judgment is the product of a settlement. Chaney Bldg. Co. v. City of Tucson,
¶ 7 American’s motion for summary judgment was based on the converse of this principle: American argued the stipulated dismissal with prejudice of Walgreen (the principal) barred Jamerson’s claim against American (the agent). On appeal, American
¶ 8 This dictum may have reflected the common-law rule in some jurisdictions in 1945, when De Graff was decided. See V. Woerner, Annotation, Release of (or covenant not to sue) master or principal as affecting liability of servant or agent for tort, or vice versa,
¶ 9 Section 12-2504 is part of Arizona’s version of the Uniform Contribution Among Tortfeasors Act (“UCATA”). See A.R.S. §§ 12-2501 to -2509 (2013). In 1984, when tortfeasors were jointly and severally liable for injury to a claimant, the legislature enacted a package of statutes granting tortfeasors a right of contribution among each other. A.R.S. §§ 12-2501 et seq.; see Roland v. Bernstein,
¶ 10 In 1987, the legislature enacted A.R.S. § 12-2506, which generally abolished joint- and-several liability by providing that, in the usual case, each defendant “is liable only for the amount of damages allocated to that defendant in direct proportion to that defendant’s percentage of fault.” AR.S. § 12-2506(A); see Roland,
The liability of each defendant is several only and is not joint, except that a party is responsible for the fault of another person, or for payment of the proportionate share of another person, if any of the following applies:
2. The other person was acting as an agent or servant of the other party.
A.R.S. § 12-2506(D)(2).
¶ 11 In Roland, we held § 12-2504 does not apply in a several-liability situation, in which each defendant is liable only to the extent of its own fault.
¶ 12 Because Walgreen is jointly and severally liable for any negligence of American, § 12-2504(1) applies to Jamerson’s settlement with Walgreen.
¶ 13 American argues § 12-2504 does not apply to vicarious liability, and points for support to Law, which held that by enacting UCATA, our legislature did not upset the common-law rule that a stipulated judgment in favor of an agent bars a claim against the principal.
¶ 14 But our reasoning in Law does not apply here. When a claimant stipulates to a judgment in favor of an agent, the agent thereby is adjudicated to have no liability, and any vicarious liability of the principal necessarily falls away. Id.; see i-501 North-point LP v. Maricopa County,
¶ 15 Here, however, we have the converse situation. Although the stipulated judgment in favor of Walgreen constitutes an adjudication on the merits of Jamerson’s claim against Walgreen, see Law,
¶ 16 In Law, we held § 12-2504 did not allow a plaintiff to pursue a vicarious liability claim against an employer after she dismissed claims against the employee-tortfea-sors.
¶ 17 We do not accept American’s contention that under Law, § 12-2504 does not apply whenever vicarious liability is alleged. American’s argument that the result of the stipulated dismissal here must be the same as in Law simply because vicarious liability is at issue misperceives the limited retention of joint liability in A.R.S. § 12-2506(D). As recited above, liability is several only except that, as applicable here, “a party is responsible for the fault of another person ... if ... [t]he other person was acting as an agent or servant of the party.” A.R.S. § 12-2506(D). To state the obvious, the principal in such a situation is jointly liable for the fault of the
¶ 18 American also argues § 12-2504 does not apply because, although Jamerson and Walgreen agreed to a stipulated dismissal with prejudice, the record contains no “release or a covenant not to sue or not to enforce judgment,” to which the statute expressly applies. The settlement here, however, resulted in a stipulated judgment that necessarily bars any claim by Jamerson against Walgreen. To hold that under these circumstances the negotiated consent judgment did not constitute a release for purposes of § 12-2504(1) would be to exalt form over substance.
¶ 19 American also points to our statement in Law that A.R.S. § 12-2504 did not apply because “the statute does not address dismissals with prejudice of pending actions.”
¶ 20 American also cites Restatement (Third) of Torts: Apportionment of Liability (2000). Pursuant to § 7, comment j, of that Restatement, “[w]hen a party is liable solely on the basis of another person’s tortious conduct, ... the party who committed the tor-tious acts or omissions and the party to whom liability is imputed are treated as a single unit for the assignment of responsibility.” When that provision applies, § 16, comment d, further provides that a settlement with one of the parties “extinguishes the liability of the others.”
¶ 21 We infer that comment d applies to the situation, not presented here, in which the fault of defendants linked by vicarious liability is to be compared to the fault of other non-settling defendants. See id. (“The nonsettling defendants will receive a credit for the share of responsibility that the factfinder assigns to the agent and vicariously liable party. Thus, there is no responsibility remaining to be assigned to any non-settling agent or vicariously liable party.”). Regardless, to the extent that § 16 and comment d are intended to apply in a situation such as this, in which the plaintiffs only claims are against the agent and the principal and the principal has settled, A.R.S. § 12-2504 precludes application of the Restatement rule. See In re Krohn,
¶ 22 Finally, in urging us to reverse the summary judgment against her, Jamerson argues that Arizona should join several other jurisdictions in holding under the common law that, absent a contrary intent of the settling parties, a settlement with the principal does not as a matter of law bar a claim
CONCLUSION
¶ 23 We vacate the judgment and remand for proceedings consistent with this opinion.
Notes
. Absent material revision after the relevant date, we cite a statute’s current version.
. Jamerson's complaint alleged both that Walgreen was negligent in cleaning the store (it was vicariously liable for American’s alleged negligence) and in hiring and supervising American. The settlement and consent judgment disposed of both components of Jamerson’s claim, but only the vicarious liability component is relevant in this appeal.
. American does not argue that A.R.S. § 12-2504 is inapplicable because the Walgreen settlement was not in good faith; nor does it argue that the settlement by its terms released American.
. Indeed, comment d to Restatement § 16 explains that it is necessary to prevent an "undeserved windfall for the plaintiff, if the plaintiff is permitted to keep the settlement proceeds and recover on the judgment against the primarily liable defendant.” Arizona’s legislature has eliminated this concern by providing in § 12-2504(1) that any such settlement reduces the amount the plaintiff may recover against the remaining tortfeasors.
. See, e.g., Wolcott v. Ginsburg,
