Supreme Court limits ICE cell phone tracking in U.S.

The U.S. Supreme Court has delivered a significant ruling, determining that government access to cell phone geolocation histories constitutes a "search" protected by the Fourth Amendment. The 6-3 decision in the case *Chatrie v. United States*, issued on June 29, mandates that agencies like Immigration and Customs Enforcement (ICE) and other federal bodies must now obtain judicial warrants based on probable cause and particularity before accessing this sensitive data.

This landmark decision effectively halts a surveillance mechanism that could have impacted millions of individuals, particularly Latino migrants. Previously, agencies could reconstruct people's daily movements by accessing information stored by companies like Google without a warrant. The ruling clarifies that while ICE and other law enforcement agencies can still use location data, they must adhere to the warrant requirement mandated by the Fourth Amendment when requesting historical data from companies.

The ruling is particularly impactful for Latino communities in the U.S., as it limits the practice of mass tracking through geofencing. It is no longer permissible for agencies to request information on all phones within a specific area simply to identify individuals present. This change aims to prevent the "fishing expeditions" that could disproportionately affect immigrant populations.

Individuals concerned about the potential misuse of their location information are advised to consult with lawyers specializing in privacy or immigration law. The precedent set by this ruling reinforces constitutional rights and provides a stronger basis for challenging future investigations that may involve unwarranted access to personal location data.
