The contents of any wire, electronic or oral communication intercepted in accordance with the provisions of this subchapter, or evidence derived therefrom, shall not be disclosed in any trial, hearing, or other adversary proceeding before any court of the Commonwealth unless, not less than ten days before the trial, hearing or proceeding the parties to the action have been served with a copy of the order, the accompanying application and the final report under which the interception was authorized or, in the case of an interception under section 5704 (relating to exceptions to prohibition of interception and disclosure of communications), notice of the fact and nature of the interception.
