   MEMORANDUM

Cherie Johnson and Maria Ignacio appeal the district court’s final judgment following the denial of their motion to substitute as new plaintiffs and class representatives in this putative class action. On appeal, Johnson and Ignacio challenge the district court’s determination that their claims were barred by the doctrine of res judicata. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

As a threshold matter, we conclude that the district court neither disregarded California res judicata law nor supplanted it with the federal common law. Consistent with 28 U.S.C. § 1738 and our precedent, the district court appropriately applied California res judicata principles, including-the requirement that there be a “final judgment on the merits.”

In applying California’s res judicata law, the district court correctly determined that Johnson’s and Ignacio’s respective claims were precluded. First, Johnson’s state agency proceedings before the California Labor Commissioner resulted in a final judgment on the merits and involved the same parties and claims in this federal action. See MHC Fin. Ltd. P’ship v. City of San Rafael, 714 F.3d 1118, 1125 (9th Cir.2013). Based on the evidence and testimony in the record, the hearing officer in Johnson’s state agency proceedings determined that she was not employed by Gevity and therefore eliminated Gevity as a party. Because none of the parties appealed the hearing officer’s decision, the California Superior Court entered judgment pursuant to California Labor Code § 98.2. That judgment “has the same force and effect as ... a judgment in a civil action,” and is therefore entitled to res judicata effect. Cal. Lab.Code § 98.2(e); see also Post v. Palo/Haklar & Assocs., 23 Cal.4th 942, 947, 98 Cal.Rptr.2d 671, 4 P.3d 928 (2000) (“If no party takes an appeal, the commissioner’s decision will be deemed a judgment, final immediately and enforceable as a judgment in a civil action.”).

Ignacio’s state agency proceedings also resulted in a final judgment on the merits and involved the same parties and claims in this federal action. See MHC Fin. Ltd. P’ship, 714 F.3d at 1125. Ignacio admitted during her administrative hearing that she lacked any factual or legal basis to hold Gevity liable for her unpaid wages and “opted to withdraw her complaint against Gevity.” The hearing officer therefore dismissed Gevity from the suit. Contrary to Ignacio’s contention, this dismissal was not without prejudice because Ignacio knowingly and affirmatively abandoned her claims against Gevity during her administrative hearing. See Gagnon Co. v. Nev. Desert Inn, Inc., 45 Cal.2d 448, 455, 289 P.2d 466 (1955) (“[A] dismissal entered in open court pursuant to stipulation ... is ordinarily effective as a retrax-it.”); Eulenberg v. Torley’s Inc., 56 Cal.App.2d 653, 657, 133 P.2d 15 (1943) (“[Wjhere it affirmatively appears that the plaintiff intended to abandon the action, ... it is treated as a retraxit.”). As in Johnson’s case, none of the parties in Ignacio’s state agency proceedings appealed the hearing officer’s decision, and the California Superior Court entered a judgment entitled to res judicata effect. See Cal. Lab.Code § 98.2(e). We reject Ignacio’s post hoc attempts to retract her express abandonment of her claims against Gevity and to unwind the state court’s final judgment. Permitting Ignacio to do so under these circumstances would encourage du-plicative litigation, waste judicial resources, nullify the administrative scheme established by California labor law, and run counter to the California legislature’s purpose of “avoiding] recourse to costly and time-consuming judicial proceedings.” Arias v. Kardoulias, 207 Cal.App.4th 1429, 1434, 144 Cal.Rptr.3d 599 (2012).

AFFIRMED. 
      
       This disposition is not appropriate for publication and is not precedent except as provided by 9th Cir. R. 36-3.
     
      
      . We grant Johnson and Ignacio’s unopposed request for judicial notice. See, e.g., Terenkian v. Republic of Iraq, 694 F.3d 1122, 1137 n. 8 (9th Cir.2012).
