Standing Rules of the United States Senate

The Standing Rules of the Senate are the parliamentary procedures adopted by the United States Senate that govern its procedure. The Senate's power to establish rules derives from Article One, Section 5 of the United States Constitution: "Each House may determine the rules of its proceedings ..."

There are currently forty-five rules, with the latest revision adopted on January 24, 2013. The most recent addition of a new rule occurred in 2006, when The Legislative Transparency and Accountability Act of 2006 introduced a 44th rule on earmarks. The stricter rules are often waived by unanimous consent.
