Utah Supreme Court
Can Utah border patrol officers stop vehicles based primarily on ethnic appearance? State v. Mendoza Explained
Summary
Border patrol officers stopped defendants’ vehicle based on their apparent Latin descent, California license plates, time of day, and alleged nervous behavior. The trial court granted defendants’ motion to suppress evidence discovered during a subsequent search of the vehicle’s trunk.

Analysis
In State v. Mendoza, the Utah Supreme Court addressed whether border patrol officers had reasonable suspicion to conduct an investigatory stop based primarily on the occupants’ apparent ethnic origin and related factors.
Background and Facts
Two Immigration Service border patrol officers observed northbound traffic on I-15 near St. George at 4:50 a.m. When they spotted defendants’ black Mustang with California plates, they pursued it at high speed to get a closer look. The officers decided to stop the vehicle based on: (1) the occupants’ apparent “Latin descent,” (2) California license plates, (3) early morning travel time, (4) alleged “jerky” driving when the Mustang changed lanes and decelerated, and (5) the occupants’ “nervous” behavior, specifically avoiding eye contact. After stopping the vehicle and arresting defendants for immigration violations, officers searched the trunk and discovered fifty-one bags of marijuana.
Key Legal Issues
The central issue was whether the officers possessed reasonable suspicion under the Brignoni-Ponce standard to justify the investigatory stop. The court also addressed the constitutionality of Utah’s Fourth Amendment Enforcement Act, which required proof of “substantial violation” before evidence could be suppressed.
Court’s Analysis and Holding
Applying the totality of circumstances test, the court found the stop unconstitutional. The officers’ justifications were insufficient: Latin appearance alone has “only minor probative value,” I-15 serves legitimate traffic from California, early morning travel is common, the alleged erratic driving was actually cooperative behavior, and avoiding eye contact cannot support reasonable suspicion. The court emphasized that accepting the State’s position would “essentially authorize the stop of all northbound vehicles on I-15 containing ‘Latin-appearing’ occupants.”
Practice Implications
This decision reinforces that ethnic appearance, standing alone or combined with innocent factors, cannot justify investigatory stops. Practitioners should scrutinize each factor cited by officers and demonstrate how the totality fails to meet constitutional standards. The court’s rejection of Utah’s Fourth Amendment Enforcement Act also shows Utah courts will not accept statutory schemes that weaken federal constitutional protections.
