During a period of extended debate it shall not be in order for a Senator other than the Majority Leader (or his or her designee) to raise a question as to the presence of a quorum, except immediately prior to a vote or when it has been more than forty-eight hours since a quorum was demonstrated. If upon a roll call it shall be as­cer­tained that a quorum is not present, then the Senate shall adjourn to a time previously decided by order of the Senate or, if no such time has been established, then to a time certain determined by the Majority Leader, after consultation with the Minority Leader. During a period of extended debate a motion to adjourn or recess shall not be in order, unless made by the Majority Leader (or his or her designee) or if the absence of a quorum has been demonstrated. Notwithstanding paragraph 1 of rule XIX, there shall be no limit to the number of times a Senator may speak upon any question during a period of extended debate. If, during the course of extended debate, the Presiding Officer puts any question to a vote, the Majority Leader (or his or her designee) may postpone any such vote, which shall occur at a time determined by the Majority Leader, after consultation with the Minority Leader, but not later than the time at which a quorum is next demonstrated. If at any time during a period of extended debate no Senator seeks recognition, then the Presiding Officer shall inquire as to whether any Senator seeks recognition. If no Senator seeks recognition, then the Presiding Officer shall again put the question as to bringing debate to a close (and the Majority Leader or his or her designee may postpone such vote in accordance with the preceding paragraph), which shall be decided without further debate or intervening motion.
