Rule 9.2. Possession of the House
A motion shall be deemed to be in the possession of the House after it has been stated by the Speaker or, at his discretion, by the Clerk or has been read by the Clerk. However, the member who has made a motion may withdraw it at any time, unless the motion is a motion to reconsider which motion shall not be withdrawn unless the approval of the House of such withdrawal is first obtained.
