Can a person be subpoena to a case that has already been dismissed?

Generally, a person cannot be subpoenaed to a case that has already been dismissed, as there is no active legal proceeding requiring their testimony or documents. However, if new evidence arises or if the case is refiled, a subpoena could potentially be issued at that time. Additionally, if the dismissal was without prejudice, the case could be reopened, which might lead to a subpoena. Always consult with a legal expert for specific situations.
