Rule 16. Entry of Appearance and Withdrawal by Counsel
(a) Counsel shall enter an appearance in writing before participating in the representation of a party to an action before the Court; however, the filing of any pleading or other paper relative to a case which contains the signature of counsel shall constitute such an entry of appearance. See Rules 13 (a) and 38.
(b) Leave to withdraw by any counsel who has entered an appearance under subsection (a) must be requested by motion in accordance with Rule 30. A motion by an appellate defense counsel must indicate the reasons for the withdrawal and the provisions which have been made for continued representation of the accused. A copy of a motion filed by an appellate defense counsel shall be delivered or mailed to the accused by the moving counsel.
