Kansas Supreme Court rules on warrantless blood tests

The Kansas Supreme Court has ruled that results from warrantless blood tests were admissible in two cases of driving under the influence, even though the statute that had authorized them was later found to be unconstitutional.

The state’s highest court said in separate decisions issued Friday that the “good faith exception” allows admission of unlawfully obtained evidence if the arresting officer had no reason to think the statute he had relied on would be declared unconstitutional after the arrest.
