The Ninth Circuit affirmed the dismissal of a pro se plaintiff's constitutional claims arising from state court arbitration proceedings. The court held that the federal lawsuit constituted a forbidden de facto appeal of the state court judgment under the Rooker-Feldman doctrine, depriving the federal court of subject matter jurisdiction.

John Torsten Loop, proceeding pro se, filed a lawsuit in the United States District Court for the Western District of Washington against the State of Washington, JAMS Mediation Arbitration and ADR Services, a retired JAMS arbitrator, and the Washington State Attorney General. The underlying dispute involved constitutional claims arising from state court proceedings that confirmed an arbitration order. Loop sought to challenge the outcome of those state court proceedings in federal court. The district court dismissed the action, ruling that it lacked subject matter jurisdiction because the claims were barred by the Rooker-Feldman doctrine. Loop appealed this dismissal to the Ninth Circuit.

The Ninth Circuit reviewed the dismissal de novo, applying the Rooker-Feldman doctrine. This doctrine prevents federal district courts from acting as appellate bodies for state court judgments. The court explained that an action constitutes a forbidden 'de facto appeal' when a plaintiff complains of a legal wrong allegedly committed by the state court and seeks relief from that court's judgment. Furthermore, claims are considered 'inextricably intertwined' with state court decisions if federal adjudication would impermissibly undercut the state ruling on the same issues. The court found that Loop's claims fell squarely within these prohibitions, as they challenged the state court's confirmation of the arbitration order. Consequently, the federal court lacked the authority to hear the case. The court also noted that it would not consider matters not specifically and distinctly raised in the opening brief.

The decision reinforces the strict jurisdictional bar of the Rooker-Feldman doctrine, preventing federal courts from reviewing state court judgments even when constitutional claims are raised. For parties involved in state court arbitration confirmations, this means they cannot bypass state appellate procedures by filing a new federal suit to challenge the state court's ruling. The case was remanded with instructions to affirm the dismissal, leaving the state court judgment on the arbitration confirmation undisturbed.
