” I’m guessing their irrelevancy will extend to Senator Cruz’s situation.”
Probably so. But that does not make it constitutional. It only makes it an opinion of the “Court”.
They make many rulings that are not constitutional. Otherwise all rulings would be 9-0. Majority is not what makes things constitutional, unless you buy what they are selling. I don’t.
They get to decide what is Constitutional and what isn’t. Their rulings stand unless and until they are overturned by a higher court or a different court.
