But who will enforce a court order if the executive branch decided to ignore it?
But the same question remains. Who’s going to enforce it?
Whoever did or didn't before. It's got nothing to do with this executive order as far as I can see.
Do you see it now?
The executive shall enforce orders, because it is bound by laws to do so, which for the executive can only be interpreted by the president?
Sounds like a power grab to me.
No? They don't do their job because the law compels them to do (often it doesn't, e.g. the police don't have any positive legal obligation to make arrests or what have you). They do their job because it's their job.
