A Wisconsin appeals court has ruled that taking blood samples without a warrant from incapacitated drivers suspected of driving drunk is unconstitutional.

The Wisconsin State Journal reports that the decision throws out a long-standing state law provision stating that incapacitated drivers are presumed not to have withdrawn consent for blood tests.
