Seems limited somewhat. If only one of two residents permits search, the other resident can’t keep them out. The case at hand isn’t clear cut. The husband refused a warrantless search but the wife later permitted it.
More precisely, if only one of two occupants is there, then that occupant gets to decide if the cops come in without a warrant or not.
When folks side with Ginsberg to oppose Scalia & Thomas, then they OUGHT to look at the issue more closely. Scalia and Thomas are not idiots.
