Warrantless DWI Tests Tossed in McNeely Opinion by Supreme Court

Today the United States Supreme Court decided the DWI case of McNeely v. Missouri. We have previously blogged on this case several times. In summary, the high Court said that police cannot take a DWI blood sample from a driver without his consent where they also did not have a warrant. This means that Warrantless DWI Tests are unconstitutional, illegal, and should not be allowed. Thus any DWI test evidence gathered without a warrant should be tossed out by a Judge.

Because the police in the Missouri case did NOT have a warrant, and didn’t’ even try to get one, AND because the driver refused to consent to testing, the Supreme Court ruled that the driver’s Fourth Amendment rights were violated. Therefore the results of the DWI blood test, and the criminal charge based on it, were tossed out, or suppressed and dismissed, by the U.S. Supreme Court.

This case means that, since Warrantless DWI testing has now been declared illegal by the highest court in the land, overruling prior Minnesota cases, the theoretical underpinnings of all of Minnesota DWI criminal laws and implied consent laws are ALL gone.  This includes the bizarre “crime” of DWI test refusal, which only exists in Minnesota and a few other states.

Minnesota DWI Attorney Max A. Keller, and other leading criminal defense attorneys, are still digesting & sifting through his far-reaching case which has obliterated Minnesota’s criminal DWI and implied consent pre-conviction driver’s licsense case law. So, for a more in-depth analysis, check back here later.  In the meantime, you may want to read this analysis by a leading national commentator on the SCOTUS website.

Max Keller has won countless jury trial cases involving misdemeanors and felonies, sex crimes, and DWI’s. He is a member of the Minnesota Society for Criminal Justice, which only allows the top 50 criminal defense attorneys in the state as members. Max is a frequent speaker at CLE’s and is often asked for advice by other defense attorneys across Minnesota.

What to Do If You Have Been Charged with a Criminal Offense

One of the questions people facing a criminal charge ask is: How long does a criminal case take? The timeline of your criminal case in Minnesota will depend on the nature and severity of the alleged crime, the speed of the criminal justice system, the duration of the trial, and whether an appeal will be necessary. Delays at any stage of the criminal justice process may impact how long your criminal case will last. Generally, however, misdemeanor cases may resolve within weeks or months, while felony cases may linger in courts for up to a year.
People accused, arrested, or charged with a crime often ask, “How much does a criminal defense lawyer cost in Minneapolis, MN?” It is difficult to accurately determine how much a criminal defense lawyer will cost. The reason is that numerous factors impact the cost of legal representation in criminal matters. These factors include the type and severity of criminal charges, the lawyer’s experience and reputation, required time and effort, and geographical location.
Social media can have legal implications, particularly when it comes to criminal cases. Since its advent, social media has become a powerful tool for communication and self-expression. As of 2023, an estimated 4.9 billion people worldwide use social media platforms such as Facebook and Instagram to share thoughts, experiences, and moments from their lives. However, in this digital age, social media activity can be used as evidence in criminal cases in Minneapolis and elsewhere.
