Court rules govern the conduct of business before courts.
They dictate how trials are conducted from commencement of an action through motions for post-judgment relief. The United States Constitution, in Articles 1-3, created the judiciary branch and defined its powers. Congress delegated rule-making authority to courts. The Supreme Court may promulgate general rules of practice and procedure for district courts and courts of appeal. The Judicial Conference may appoint advisory committees, composed of attorneys, judges, and scholars, to propose rules.
