In Maryland, a motion for appropriate relief could refer to a motion filed by a party on the ground of any newly discovered evidence.
Maryland Rule 4-331 reads as follows:
Rule 4-331. Motions for new trial.
(c) Newly discovered evidence. The court may grant a new trial or other appropriate relief on the ground of newly discovered evidence****
A motion for appropriate relief can vary from state to state. For example in North Carolina a motion for appropriate relief can be filed for relief from errors committed in the trial division, or other post trial relief. Law specifies a time limit for filing these motions.
Example of a state statute on Motion for appropriate relief
North Carolina General Statute says that generally a motion for appropriate relief should be in writing. and should be filed timely. Oral motions are also allowed when it is made in open court, or before the judge who presided at trial or before the end of the session if made in superior court or within 10 days after entry of judgment. Any party is entitled to a hearing on questions of law or fact arising from the motion and any supporting or opposing information presented unless the court determines that the motion is without merit. The court can also determine if an evidentiary hearing is required or not. If an evidentiary hearing is held, the moving party has the burden of proving by a preponderance of the evidence every fact essential to support the motion.
