Blood Tests for DWI in Minnesota

Challenging Chemical Test Evidence in a DWI Case

The Minnesota Court of Appeals determined that a search warrant is required before a blood test can be performed on a DWI suspect. It was once a crime to refuse a blood test, but the law now reflects that you cannot be penalized for not consenting to a blood test without a warrant. Although breath tests are typically favored over blood tests, this is a very big deal for DWI law.

Cases where warrants were not secured prior to a blood draw may be challenged, as the courts have now decided that this is an “unreasonable search and seizure” and a violation of a person’s constitutional rights. Any evidence obtained from an illegal blood test cannot be used in court, and could result in a dismissal of the case. Read more about this change to Minnesota law here.

Why Take a Test You Aren’t Legally Required to Take?

The debate over public safety and personal privacy when it comes to DWI testing is a complicated one, but one thing is now clear: those accused of DWI cannot be forced to submit to an invasive test simply because of an officer’s suspicion. Since people have a right not to incriminate themselves under the Fifth Amendment, it is unjust that they should be served punishment for refusing to confirm or deny a suspicion when they do not legally have to submit evidence against themselves.

Blood tests require the use of a needle, making them far more invasive than a breath test. The accuracy of blood tests is also questionable. If blood samples are not handled properly, they can become corrupted and produce inaccurate results. If you were arrested on suspicion of DWI after refusing an illegal blood test, we urge you to assert your right to legal representation and get in touch with a Minneapolis DWI lawyer at Caplan & Tamburino Law Firm, P.A. as soon as possible.
