How it’s Supposed to Work
Remember, too, that federal and state officials take an oath to uphold the Constitution.
They do not take an oath to uphold judges’ opinions.
This means that if I’m a president or governor and a court issues a ruling I truly believe is unconstitutional, I have a duty to ignore it. Otherwise, I’m violating my oath.
“But what of rogue legislators or presidents?” some may ask. Well, what of rogue judges (who apparently are everywhere)?
The answer is the Founders’ one: No branch can intrude into the others’ spheres. This doesn’t mean there aren’t checks and balances. If, for example, a president believes a law is unconstitutional and refuses to enforce it, or takes an allegedly unconstitutional executive action, Congress can try to remove him; it can also impeach and remove renegade judges. As for House representatives themselves, the remedy is removal via the ballot box. This is why they must run for re-election every two years: Since they’re meant to be the most powerful branch (e.g., spending bills must originate in the House, and only it can file impeachment charges), they’re placed closest to the people’s reach.
Power means nothing, though, if not exercised. If congressional and executive powers are outsourced, it then can reduce us to what we’ve become: a government of, by and for judicial oligarchs.
So, no, President Trump doesn’t have to obey blatantly unconstitutional court opinions. This said, with how he’s shaking up the system and busy draining the bureaucratic swamp, it’s perhaps politically prudent to remedy the current judicial adventurism through the higher courts, as he’ll almost assuredly win on appeal. At some point, though, it will be time to drain that fetid judicial swamp and address the real constitutional crisis: the rule of judges who would be kings.
