Which term refers to a defendant being sent back into custody by the court?

The term "remand" specifically refers to the action taken by a court when a defendant is sent back into custody. This can happen for various reasons, such as violation of bail conditions, engaging in criminal behavior while on probation, or other circumstances that require the court to reassess the defendant's situation.

When a judge remands a defendant, they are effectively deciding that the individual should be returned to custody for the time being, pending further legal proceedings or until the next scheduled court date. This action is integral to the judicial process, as it allows the court to maintain authority over individuals who may pose a risk or who may not adhere to legal stipulations.

The other options, while relevant in the context of legal proceedings, do not describe the act of sending a defendant back into custody. For instance, "subpoena" relates to a legal document ordering someone to attend court, "recidivism" refers to the tendency of a convicted criminal to reoffend, and "restitution" involves compensating victims for losses caused by criminal activity. Thus, "remand" is the most accurate term for the scenario described in the question.
