Houston's Fourth Amendment Ordinance Sparks Conflict with Texas Governor Abbott Over Immigration Enforcement

The Houston City Council recently enacted an ordinance clarifying the boundaries of local police cooperation with federal immigration enforcement. The ordinance explicitly prohibits officers from prolonging detentions solely because an Immigration and Customs Enforcement (ICE) civil administrative warrant is discovered during a background check.

This move has drawn sharp criticism from Texas Governor Greg Abbott, who responded by threatening to withhold $110 million in state public safety grants unless the ordinance is repealed. Additionally, Texas Attorney General Ken Paxton filed a lawsuit, arguing that the ordinance violates a state law prohibiting local entities from limiting peace officers' cooperation with federal immigration authorities.

The ordinance, however, is framed around compliance with the Fourth Amendment. It states:

"During a field encounter, officers may temporarily detain an individual only as long as reasonably necessary to complete the legitimate purpose of the initial stop or investigation. An ICE administrative warrant is civil in nature and, alone, does not justify a stop, arrest, or continued detention by local law enforcement, like HPD. If independent reasonable suspicion of a criminal offense sufficient to justify arrest or continued detention does not exist, the individual must be released."

This policy, while inconvenient for ICE, aligns with Supreme Court precedent on Fourth Amendment limits. In the 2015 case Rodriguez v. United States, the Court ruled that extending a traffic stop beyond its original purpose violates constitutional protections against unreasonable seizures. The case involved a motorist detained for an additional seven or eight minutes after receiving a warning, during which a drug-sniffing dog was deployed. The Court held that such prolongations are only permissible if officers have reasonable suspicion of criminal activity.

Houston’s ordinance appears to address incidents where local officers have extended traffic stops to facilitate immigration arrests. For example, in July 2023, Houston police stopped a driver for an expired registration. After an ICE warrant was found in a database search, officers transported the driver to the Jersey Village Police Station—about 20 miles away—to hand him over to ICE. Similarly, in August 2023, another Houston officer assisted ICE by transporting a driver to a police station following a red-light violation, leading to an immigration arrest. In both cases, there was no independent reasonable suspicion of a criminal offense to justify the prolonged detentions.
