Wesley Brooks agreed to provide the blood and urine samples that became the key evidence in each of his three drunken-driving convictions.
But can Brooks, of Prior Lake, and thousands of others like him across Minnesota, truly be said to have "consented" to providing a sample if refusing to do so results in criminal charges?
Yes, the Minnesota Supreme Court said in a ruling Wednesday heralded by law enforcement, although many legal observers say it leaves unanswered questions about the constitutionality of Minnesota's implied-consent law. That law, established in 1961, says anyone issued a driver's license has automatically agreed to chemical testing during a DWI arrest and the results can be used against them in court. Refusal results in criminal charges.
In a unanimous decision, the court rejected Brooks' argument that he didn't have a choice as to whether he should provide blood and urine samples, simply because refusing to do so is a crime in Minnesota.
"A driver's decision to agree to take a test is not coerced simply because Minnesota has attached the penalty of making it a crime to refuse the test," Chief Justice Lorie Gildea wrote in the opinion.
Bill Lemons, traffic safety resource prosecutor for the Minnesota County Attorneys Association, applauded the ruling as a sign that law enforcement has been doing things right.
"I think it makes clear that if you follow the implied-consent procedures and law, then the consent is valid and the test results admissible," Lemons said.
Ruling: 'Brooks consented'
The Brooks ruling was the first case analyzing how Minnesota law could be affected in the wake of Missouri vs. McNeely, an April U.S. Supreme Court decision that said police officers must try to get a search warrant for a blood sample if they want it to hold up in court. The fact that alcohol quickly dissipates in the blood is no longer justification for not getting a judge's sign-off, the high court reasoned.
