The case the court agreed Friday to hear involves Gerald Mitchell. He was arrested in Sheboygan for driving while intoxicated in 2013 in Wisconsin. Mitchell was too drunk to take a breath test and became unconscious after being taken to a hospital. His blood was then drawn without a warrant. Mitchell was ultimately convicted of driving while intoxicated.
Mitchell says the blood draw was a search that violated his constitutional rights, but Wisconsin's Supreme Court upheld his convictions. Mitchell says 29 states have similar laws.
