Settlement and Discontinuance (Arbitration Rule 55) At any time before the Award is rendered, parties may jointly request that the Tribunal discontinue the proceeding if they settle the dispute or for any other reason.
Interestingly, however, the time limits within which such motions may be filed, differ under the Federal Arbitration Act (FAA). Motions to confirm must be filed within a year after the award is made, whereas motions to vacate, must be filed within three months. See 9 U.S.C. Sections 9 and 12.

Motions to Dismiss. (1) Motions to dismiss a claim prior to the conclusion of a party's case in chief are discouraged in arbitration. (2) Motions under this rule must be made in writing, and must be filed separately from the answer, and only after the answer is filed.
