If your criminal defense attorney is  able to suppress the use of the blood, breath or urine test results  in your Minnesota DWI case, you will have found the key to winning your case. The use of a chemical test result by the prosecution is critical to a successful DWI prosecution.
How does an experienced DWI attorney suppress the chemical test result? The defense lawyer will   file a motion with the court requesting that  the chemical test result not be allowed to be used  against you  at trial  on the grounds that the test result was obtained in violation of the Fourth Amendment.   What does the suppression of the chemical test for intoxication mean for your case? If the judge grants the motion to suppress the evidence, the prosecution  will lose the use of powerful scientific evidence to prove your intoxication at trial. The only evidence left  over  will be your driving conduct,  field sobriety test result, if any,  and statements you may have made about  alcohol or drug use. You now have plea bargaining strength and a chance for an acquittal at trial.
        How were my Fourth Amendment rights violated by the police? There are only two ways the police can obtain a warrantless search for  blood alcohol concentration or the presence of a controlled substance in your body. The first is by obtaining your consent to conduct a warrantless search. The  second is by proving emergency conditions existed at the time of arrest which would justify the police in not first obtaining a search warrant from a judge. If the police did  not obtain your consent to search and there was no emergency circumstance,  police must first obtain a search warrant. If they failed to do so, your Fourth Amendment rights were violated.
