Caveat: on a preliminary basis in most of the decisions
Important to differentiate SCOTUS saying "there isn't a compelling reason to block this power before we decide" and "here's our decision about the legality of this power"

I'm half-curious if Roberts is playing for time to avoid a constitutional crisis, figuring it's better to cede a temporary power (and avoid the executive stuffing the bench or whatever insane shit they'd try) than to cast it in case law. Not great for the rule of law, but I can see the realpolitik (which Marbury v. Madison shows has always been a consideration for inter-branch squabbles)
