Wisconsin's law enforcement and justice systems have struggled to establish parameters for warrantless blood draws that promote effectiveness, consider limited resources, and protect individuals' constitutional rights. Read the status of warrantless blood draws after recent supreme court opinions.
For many years, Wisconsin's pleading standard for litigation appeared to differ from the federal-court standard, but in 2019 the Wisconsin Supreme Court announced the standards are essentially the same. In Cattau, the court clarified this decades-long misunderstanding.
A man convicted of operating while intoxicated (OWI), third offense, argued that a blood test should have been suppressed because he did not freely give consent. Recently, the Wisconsin Supreme Court (5-2) upheld the conviction, but with differing views on application of the state's implied consent law.
