This case concerns the constitutionality of a highly intrusive law enforcement practice: the use of geofence warrants. Geofence warrants compel tech companies like Google to provide to law enforcement location data from every cell phone likely to have been within a certain area during a given time window. Then, law enforcement officers decide for themselves which users to focus on, and demand additional location information—and eventually identifying information—for the users they select. Geofence warrants raise grave constitutional concerns, including that (1) they authorize dragnet searches that sweep up the private data of many people without probable cause to believe that all or any of them were involved in any crime, and (2) they allow law enforcement officers to decide which users to focus on for additional data collection without judicial oversight. This case therefore has significant implications for Texans’ ability to secure their digital privacy and property against unjustified government intrusion.

The American Civil Liberties Union, ACLU of Texas, and the Texas Civil Rights Project filed a class-action lawsuit on May 4, 2026, seeking a temporary restraining order and preliminary injunction to block several provisions of Senate Bill 4 (88-4) from going into effect May 15. The 2023 law is one of the most extreme anti-immigrant laws ever passed by any state legislature in the country.

Texas has growing Hispanic and Black populations that helped propel record voter turnout in the November 2020 election. The Texas Legislature responded to this increased civic participation with an omnibus election bill titled Senate Bill 1—SB 1 for short—that targeted election practices that made voting more accessible to traditionally marginalized voters like voters of color, voters with disabilities, and voters with limited English proficiency. Since 2021, SB 1 has resulted in tens of thousands of lawful votes being rejected, and it remains a threat to democracy in Texas.
