> The new rules remove the requirement of 60 votes in order to begin debate on legislation and allow the minority two amendments to measures that reach the Senate floor, a change implemented as a standing order that expires at the end of the current term. In the new rules, the amount of time to debate following a motion to proceed has been reduced from 30 hours to four. Additionally, a filibuster on the motion to proceed will be blocked if a petition is signed by eight members of the minority, including the minority leader.
