One of the most powerful — and contested — surveillance tools in the U.S. government's arsenal officially expired tonight, but Americans shouldn't expect the spying to stop anytime soon.

Section 702 of the Foreign Intelligence Surveillance Act, which allows U.S. intelligence agencies to collect electronic communications of foreign targets overseas — often sweeping in Americans' messages in the process — hit its sunset deadline on June 13, 2026. Congress failed to reauthorize it in time.

The catch: the law's expiration doesn't immediately shut anything down. According to Ars Technica, active certifications issued under Section 702 remain valid until March 2027, meaning the surveillance programs operating under those certifications can legally continue for nearly another year.

Section 702 has been a flashpoint in debates over civil liberties since its existence was publicly revealed. Critics argue it enables warrantless collection of Americans' private communications under the guise of targeting foreigners. Supporters, including intelligence agencies, say it is an irreplaceable tool for tracking terrorist threats and foreign adversaries.

The expiration-without-ending scenario is an unusual legal limbo: the authorizing statute is gone, but the machinery it set in motion keeps running under previously granted permissions. Whether Congress acts to reauthorize, reform, or permanently kill Section 702 before those certifications expire in 2027 will be the central question going forward.

For ordinary people, this matters because Section 702 is the legal backbone behind some of the most expansive government data collection programs ever disclosed — and its fate directly shapes how much privacy anyone communicating digitally can reasonably expect.
