Sunset provision
Legal measure / From Wikipedia, the free encyclopedia
For other uses of "Sunset", see Sunset (disambiguation).
In public policy, a sunset provision or sunset clause is a measure within a statute, regulation 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 Unlike most laws that remain in force indefinitely unless they are amended or repealed, sunset provisions have a specified expiration date.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.
