Fourth Amendment Protection Act
US laws limiting cooperation with federal mass surveillance

The Fourth Amendment Protection Acts, are a collection of state legislation aimed at withdrawing state support for bulk data (metadata) collection and ban the use of warrant-less data in state courts. They are proposed nullification laws that, if enacted as law, would prohibit the state governments from co-operating with the National Security Agency, whose mass surveillance efforts are seen as unconstitutional by the proposals' proponents. Specific examples include the Kansas Fourth Amendment Preservation and Protection Act and the Arizona Fourth Amendment Protection Act. The original proposals were made in 2013 and 2014 by legislators in the American states of Utah, Washington, Arizona, Kansas, Missouri, Oklahoma and California. Some of the bills would require a warrant before information could be released, whereas others would forbid state universities from doing NSA research or hosting NSA recruiters, or prevent the provision of services such as water to NSA facilities.
History
The events of the 9/11 terrorist attacks led to some sweeping changes in national security policies. Through the enactment of Title II: Enhanced Surveillance Procedures of the USA PATRIOT Act of 2001, many government agencies were granted increased power of surveillance. Controversy arose from the increased surveillance that was granted. Proponents of the act argued that the increased surveillance measures were necessary for the protection and safety of the country, while detractors argued that the increased power of surveillance infringed upon Fourth Amendment protections.
Among the controversial programs that were put into place was the President's Surveillance Program, which embodied the Terrorist Surveillance Program.

Why this record matters

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 21, 2026. The linked authority identifier is Q16981276. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2013, 2014 and 2001.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
