STUART ROBINSON, No. 20-35669 Plaintiff-Appellant, D.C. No. 3:19-cv-05695-RJB v. MEMORANDUM* GREATER LAKES RECOVERY CENTER, Defendant-Appellee. Appeal from the United States District Court for the Western District of Washington Robert J. Bryan, District Judge, Presiding Submitted May 18, 2021** Before: CANBY, FRIEDLAND, and VANDYKE, Circuit Judges. Barbara A. Stuart Robinson appeals pro se from the district court’s summary judgment in her 42 U.S.C. § 1983 action alleging federal and state law claims related to her involuntary detention and treatment at defendant Greater Lakes * This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3. ** The panel unanimously concludes this case is suitable for decision without oral argument. See Fed. R. App. P. 34(a)(2). Recovery Center (“Greater Lakes”). We have jurisdiction under 28 U.S.C. § 1291. We review de novo. City of Martinez v. Texaco Trading & Transp., Inc., 353 F.3d 758, 761 (9th Cir. 2003). We affirm. The district court properly granted summary judgment for Greater Lakes on the basis of res judicata because Robinson raised, or could have raised, her claims in her prior Washington state court action, which involved the same parties and resulted in a final judgment on the merits. See Holcombe v. Hosmer, 477 F.3d 1094, 1097 (9th Cir. 2007) (federal court must apply state law regarding res judicata to a prior state court judgment); Ofuasia v. Smurr, 392 P.3d 1148, 1154 (Wash. App. 2017) (setting forth elements of res judicata under Washington law); Karlberg v. Otten, 280 P.3d 1123, 1130 (Wash. App. 2012) (“[R]es judicata prohibits the relitigation of claims and issues that were litigated, or could have been litigated, in a prior action[.]”). AFFIRMED. 2 20-35669
