Not for many years. A criminal case cannot be dismissed for many years after it is closed. Criminal file is the need of case management. As long as the criminal information is entered, the case will not be dropped. Only misjudged cases have the problem of withdrawing cases. If it wasn't a wrong case, it wouldn't be dropped. A criminal case that does not meet the conditions for filing a case may be closed at any time.
