Unless the Supreme Court shall otherwise order, orders imposing suspension or disbarment shall be effective thirty days after entry. The disbarred or suspended attorney, after entry of the order, shall not accept any new retainer or engage as an attorney for another in any new case or legal matter of any nature. However, during the period from the entry date of the order and its effective date the attorney may wind up and complete on behalf of any client, all matters which were pending on the entry date.
