The USA PATRIOT Act was passed by the United States Congress in 2001 as a response to the September 11, 2001 attacks. It has ten titles, each containing numerous sections. Title II: Enhanced Surveillance Procedures granted increased powers of surveillance to various government agencies and bodies. This title has 25 sections, with one of the sections (section 224) containing a sunset clause which sets an expiration date, December 31, 2005, for most of the title's provisions. This was extended twice: on December 22, 2005 the sunset clause expiration date was extended to February 3, 2006 and on February 2 of the same year it was again extended, this time to March 10.
