A sunset provision is a legal term that traces its origins back to Roman law. It refers to a clause or condition in a statute or regulation that specifies its expiration date, after which it will cease to have effect unless extended or renewed. This tool is used in various areas of legislation, both historical and contemporary, to limit the power granted by a law, often in emergency situations. Notably, it is used in the United States for federal laws needing renewal and to comply with financial regulations like the Byrd Rule. It is also seen in state-level laws and international legislation, with varying terms and conditions. The use of sunset provisions can fluctuate in popularity, influenced by factors like legislative changes and societal satisfaction.
Au public policy, a sunset provision ou sunset clause is a measure within a statute, règlement or other law that provides for the law to cease to be effective after a specified date, unless further legislative action is taken to extend it. Unlike most laws that remain in force indefinitely unless they are amended or repealed, sunset provisions have a specified expiration date. This is not applicable in legal systems where the concept of desuetude applies.
