REMAND

To send back.

A higher court may remand a case to a lower court so that the lower court will take a certain action ordered by the higher court. A prisoner who is remanded into custody is sent back to prison subsequent to a preliminary hearing before a tribunal or magistrate until the hearing is resumed, or the trial is commenced.

REMAND

A remand is an appellate court's act in returning a case to a lower court, usually unnecessary when the appellate court affirms the lower court's judgment. When the Supreme Court reverses or vacates a state court judgment, it customarily remands for "proceedings not inconsistent" with the Court's decision.
