Rule V of the Standing Rules of the United States Senate, established by the United States Senate Committee on Rules and Administration, governs amendments to the rules and suspension of the rules.
Opening a business day
Paragraph 1 states that there shall be no motion to suspend, modify, or amend any part of a rule or rule itself except on one day's notice in writing. The notification is to specify precisely the rule or part proposed to be suspended, modified, or amended, and the purpose for such. Any rule may be suspended without notice by the unanimous consent of the Senate, except as otherwise provided by the rules.
Paragraph 2 states that the rules of the Senate shall continue from one Congress to the next Congress unless they are changed as provided in these rules.
