Acting spontaneously without prompting from another party. Usually applied to actions by a judge, taken without a prior motion or request from the parties.
One situation when a party might encourage a judge to move sua sponte is when that party is preserving a special appearance (usually to challenge jurisdiction), and therefore cannot make motions on its own behalf without making a general appearance . Common reasons for an unprompted sua sponte is when the judge determines that the court does not have subject matter jurisdiction or that the case should be moved to another judge because of a conflict of interest, even if all parties disagree.
Notable Cases
- CARLISLE v. UNITED STATES (94-9247), 517 U.S. 416 (1996) — The Supreme Court ruled that a District Court could not move sua sponte to grant a judgement of acquittal (notwithstanding the verdict) to remedy the late filing of the equivalent motion. [1]
- TREST v. CAIN (96-7901), 94 F.3d 1005 — The Court of Appeals moved sua sponte to reject a habeas corpus claim because of procedural defect , citing an obligation to do so. The Supreme Court ruled that this was neither obligatory nor permitted. [2]
