This document discusses the expiry and repeal of statutes. It defines a statute as a written law passed by a legislative body. It notes that statutes can expire after a specified time if they are temporary. For an expired statute to continue being effective, it must be revived by a new statute. A statute can be repealed, or abolished, either expressly through explicit language in a new statute or impliedly if a new statute makes the old one obsolete. When a statute is repealed, it is considered void and without any effect, as if it had never existed. The effects of repeal include removing all rights created under the repealed act and making the statute ineffective.
