A little more than a year ago the United States Supreme Court decided a case that is having a significant effect on DUI cases around the country. In April, 2013, the Court decided the case of Missouri v. McNeely, 133 S.Ct. 1552, 185 L.Ed.2d 696 (2013). This post, and several posts to come, will look at McNeely and discuss its effect on DUI cases. This post will provide a background to that discussion.
Police in the state of Missouri stopped Mr. McNeely because he was driving erratically. After field sobriety tests he was arrested for DUI. The officer took him to the station for a breath test. Mr. McNeely refused that test. The officer then took him to the hospital where he was given a blood test, despite his refusals. The officer did not obtain a warrant for the blood test. Mr. McNeely’s blood test result was over the legal limit.
Mr. McNeely’s lawyer filed a motion to suppress the blood test result. He argued in that motion that the police were required to get a warrant to draw Mr. McNeely’s blood, before they drew his blood. Because they did not obtain a warrant that blood draw violated the Fourth Amendment to the United States Constitution. Mr. McNeely’s lawyer asked the court to exclude the test because of that constitutional violation.
