Fourth Amendment

Mesa v. Hernandez provides a qualified immunity quandary. If Agent Mesa wins his qualified immunity claim, other government officials in the future may lose their qualified immunity claims. 

United States Border Patrol Agent Jesus Mesa, Jr., shot and killed Sergio Adrian Hernandez Guereca, a fifteen-year-old Mexican national, who was standing on the Mexico side of the U.S./Mexico border. At the time of the shooting Agent Mesa didn’t know that Hernandez was a Mexican citizen. 

The question of most interest to state and local governments in Mesa v. Hernandez is whether qualified immunity may be granted or denied based on facts – such as the victim’s legal status – unknown to the officer at the time of the incident.

Elijah Manuel was arrested and charged with possession of a controlled substance even though a field test indicated his pills weren’t illegal drugs. About six weeks after his arrest he was released when a state crime laboratory test cleared him.  

If Manuel would have brought a timely false arrest claim it is almost certain he would have won. But such a claim would not have been timely because Manuel didn’t sue within two years of being arrested or charged.

In Birchfield v. North Dakota the Supreme Court held 5-3 that states may criminalize an arrestee’s refusal to take a warrantless breath test. If states criminalize the refusal to take a blood test police must obtain a warrant. The State and Local Legal Center (SLLC) filed an amicus brief arguing that states should be able to criminalize warrantless refusal to consent when a person is arrested upon suspicion of drunken driving.   

The National Conference of State Legislatures reports that 15 states currently criminalize refusal to consent. Criminal penalties typically include fines and jail time.    

A police officer stopped Edward Streiff after he left a suspected drug house. The officer discovered Streiff had an outstanding warrant, searched him (legally), and discovered he was carrying illegal drugs. The Supreme Court held 5-3 that even though the initial stop was illegal, the drug evidence could be admissible against Streiff in a trial.

Justice Sotomayor’s dissenting opinion in Utah v. Strieff  notes how common outstanding warrants are not just in the county where the arrest in this case occurred but also in Ferguson, Missouri (16,000 warrants out of 21,000 people).

State implied consent statutes criminalizing a person’s refusal to take a warrantless chemical blood alcohol test upon suspicion of drunk driving are constitutional, argues the State and Local Legal Center (SLLC) in a Supreme Court amicus brief.

All 50 states have adopted implied consent laws requiring motorists as a condition of driving in the state to consent to a blood alcohol content (BAC) test if they are suspected of drunk driving. If motorists refuse to consent typically their driver’s license is temporarily suspended. NCSL reports that 15 states also currently criminalize refusal to consent. Criminal penalties typically include fines and jail time.
