Rule 13.040 - RELATIONSHIP TO COURT JURISDICTION AND APPLICABLE RULES(1) A case filed in the circuit court remains under the jurisdiction of that court in all phases of the proceedings, including arbitration. Except for the authority expressly given to the arbitrator by these rules, all issues shall be determined by the court of jurisdiction.(2) Until a case is assigned to the arbitrator, Oregon Rules of Civil Procedure apply. After a case is assigned to an arbitrator, these arbitration rules apply except where an arbitration rule states that a Rule of Civil Procedure applies.(3) Once a case is assigned to arbitration, all motions against the pleadings, all motions for discovery, and all similar pretrial motions not then resolved will be submitted to the arbitrator only and determined by the arbitrator. The arbitrator's determination, however, will apply only during the arbitration proceeding. If a request for trial de novo is filed, such matters may be raised again. If the arbitrator's decision on a pretrial motion will prejudice a party on trial de novo, that party may file an appropriate motion with the court.Or. Uni. Trial. Ct. R. 13.040
