Fourth Amendment
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
Facts of the case
So this drunkard Mitchell was being a total piece of shit, driving under the influence. In Wisconsin, the legal limit is 0.08% blood alcohol level. This motherfucker was 0.222, nearly four times above the legal limit.
This motherfucker was so drunk in fact, he passed out in the squad car, so the cops had to take his dumb ass to the hospital instead of jail.
At the hospital, he passed out again, so the cops had the hospital take a blood test to determine how drunk this motherfucker was. The astute of you will say, “Hey, that’s a non-consensual search without a warrant.” You’d be right. But Wisconsin has a law that says if you obtain a driver’s license, you automatically agree to such a search.
Anyway, Mitchell thinks this is some bullshit end-run around the 4th amendment. So after trying his level best in Wisconsin court to get them to drop the results of this search, they were like “fuck you, you drunk motherfucker. We need to get your drunk ass off the streets.”
While SCOTUS acknowledges the exigent-circumstances rule allows for a blood test when someone is unconscious, it would have to be a situation where they needed to do so to prevent destruction of evidence, or to save a life. But in this case, the police did have time to get a warrant. So 5:4 decision for Mitchell.
While Ginsburg, Kagan, and Sotomayor dissented, they argued that the exigent circumstances rule shouldn’t apply to this bullshit rule in Wisconsin. That the state can’t create a law that basically exempts them from the limits in the Constitution. So they seemed to weirdly side with Mitchell, while still dissenting from the majority opinion which allows the rule, but requires a warrant be obtained in this case, since they had time to do so.
