A device for controlling prolonged debates in parliament is called a guillotine. In parliamentary procedure, a guillotine is a time management mechanism that sets a time limit for debate on a particular bill or motion. Once the time limit is reached, a vote is taken to decide whether to move to the next stage of the legislative process, such as a final vote. The purpose of a guillotine is to prevent filibustering or the obstruction of legislation by one or more members of parliament through prolonged debate. The use of a guillotine allows for a more efficient and effective legislative process by ensuring that bills and motions are debated and voted on in a timely manner. In contrast, adjournment, prorogation, and dissolution are parliamentary procedures that relate to the ending of parliamentary sessions or the life of a parliament, and do not involve the management of debates.
