[2] Appellate courts remand cases whose outcome they are unable to finally determine.
For example, cases may be remanded when the appellate court decides that the trial judge committed a procedural error, excluded admissible evidence, or ruled improperly on a motion.
Alternatively, it may be "with instructions" specifying, for example, that the lower court must use a different legal standard when considering facts already entered at trial.
Finally, it may remand a case upon concluding that the lower court made a mistake and also did not adjudicate issues that must be considered.
