AKA the Supreme Court.<p>Edit: I think the end of your comment was edited in. Regarding waiting, often it&#x27;s because nobody considered it problematic at the time. Many rulings striking down laws are overturning previous rulings upholding those laws, and are rarely unanimous.<p>Find me a law that was overturned unanimously, would be struck down by any court looking at it, yet was both law and enforced for decades because nobody looked at it.
