Functus officio

Functus officio refers to an officer or agency whose mandate has expired, due to either the arrival of an expiry date or an agency having accomplished the purpose for which it was created.[1] When used to describe a court, it can refer to one whose duty or authority has come to an end: "Once a court has passed a valid sentence after a lawful hearing, it becomes functus officio and cannot reopen the case."
