When a Senate debate is brought to a swift end, it's done with a procedure called cloture. Cloture is most often used to end a filibuster.

Other governments, including the U.K. and Australia, have similar rules for halting debate. The United States first adopted cloture in 1919 as a response to filibusters, which occur when a Senator speaks at great length, usually to avoid voting on a bill that he or she doesn't support. Filibusters can go on for hours—but when at least 60 Senators vote for cloture, all debate stops and a vote must occur. Cloture means "closure" in French.
