Orders extending time; notice to opposing party

1. No order, made on ex parte application and in the absence of the opposing party, provided he has appeared, granting or extending the time to file any paper or do any act shall be valid for any purpose in case of objection, unless written notice thereof is given to such opposing party not later than the end of the next judicial day. 2. Such notice shall be given as other notices are given, or may be given by registered mail sent to the last-known address of the attorney for such party, or, if he has no attorney, to such party himself. If the address of such attorney or party is not known, then the notice may be addressed to such attorney or party in care of the clerk. [Added; effective January 1, 1980.]
