Just over a year ago, the Supreme Court of the United States issued a rare ruling on a case involving driving under the influence (DUI). The case was Birchfield v. North Dakota, and it allowed police to perform breath tests on people they've arrested for DUI, even if they don't have a warrant. However, warrantless blood tests on DUI arrestees violated the Fourth Amendment.
The case was a recent one, only issued on June 23, 2016. Some DUI cases that are currently winding their way through the court involved people who were arrested before Birchfield was decided. Now, the neighboring state of New Mexico has decided that the rules of Birchfield should apply to those cases as well.
DUI Suspect Convicted for Refusing Blood Test
In the early morning of April 23, 2011, New Mexico police conducted a sobriety checkpoint. One of the people they pulled over was Laressa Vargas. She showed signs of inebriation, failed field sobriety tests, and was arrested. However, when police requested she take a breathalyzer, she blew a 0.04% and then a 0.05%, well below the legal limit. Suspecting that she was under the influence of drugs, police asked Vargas to take a blood test, but she refused. She was then charged with aggravated DUI, which in New Mexico involves refusing to take a blood or breath test and showing signs of impairment, and was convicted.
At no point did the police have a warrant for the blood or the breath test.
Vargas appealed her conviction, but her appeal took years. During that time, the Supreme Court issued its opinion in Birchfield, which said warrantless blood tests violated the Fourth Amendment.
New Mexico Retroactively Applies Protections of Birchfield
When Vargas' appeal finally reached the New Mexico Supreme Court, the judges there decided that the protections of Birchfield extended to protect her, even though her case started before that landmark decision. That decision, New Mexico v. Vargas, was only just made on October 5, 2017.
What This Means for Arizonans Convicted of DUI
While Vargas happened in New Mexico, not Arizona, that does not mean that it can't impact the law in our own state. New Mexico is a neighboring state with many of the same values and much of the same culture that we find in Arizona, so courts in Arizona treat it as a “sister jurisdiction” and frequently follow key decisions that come from New Mexico. This means Arizonans who have been convicted for DUI based on warrantless blood tests could benefit from appealing their conviction.
