Fourth Amendment Is Not For Sale Act

The Fourth Amendment Is Not For Sale Act is proposed federal legislation that would prohibit U.S. government agencies, including law enforcement and intelligence services, from purchasing data from commercial brokers that they would otherwise need a warrant or court order to obtain. The bill passed the House in 2024 but has not become law.

In plain English
Stopping agencies from buying your data.

It's a proposed law that would stop federal agencies from buying personal data — like location records — from companies when the Constitution would normally require them to get a warrant first.

Simple example
Under the bill, a federal agency could not pay a data broker for cellphone location records of Americans if obtaining the same records directly from a phone carrier would require a judge-approved warrant.
Why it matters
What the term actually changes.
Closing A Loophole

Supporters say agencies have used commercial data purchases to access information that courts have said is protected by the Fourth Amendment, bypassing warrant requirements.

Law Enforcement Tools

Opponents and some agencies argue that commercially available data is a useful investigative resource and that restrictions could impede counterterrorism, immigration, and criminal probes.

Test Case For Privacy Law

The bill's progress signals how Congress may approach broader questions about commercial surveillance and the boundary between private markets and constitutional protections.

How it works
The mechanics, in practice.
Purchase Restrictions

The legislation would bar covered federal agencies from buying or otherwise obtaining from third parties certain categories of data — including location and online activity — about U.S. persons.

Warrant Standard

Agencies would need to use traditional legal process, such as a warrant, subpoena, or court order, to acquire data that falls within the bill's scope.

Legislative Status

The House passed the measure in 2024, but it requires Senate passage and a presidential signature to take effect; until then, existing rules on government data purchases remain in place.
