Expungement
（重定向自Expunction）
In the common law legal system, an expungement proceeding is a type of lawsuit in which a first time offender of a prior criminal conviction seeks that the records of that earlier process be sealed, there for making the records unavailable through the state or Federal repositories. If successful, the records are said to be "expunged". Black's Law Dictionary defines "expungement of record" as the "Process by which record of criminal conviction is destroyed or sealed from the state or Federal repository." While expungement deals with an underlying criminal record, it is a civil action in which the subject is the petitioner or plaintiff asking a court to declare that the records be expunged.
