What happens if the Executive Branch defies a Supreme Court order?

What “the bank”?

I suppose nobody’s tried to force the government to pay its debt in court so far. One item that comes to mind is attaching payments that employers or tariff payers make to the government via their bank which would normally then be forwarded to whatever account the IRS or Customs use.

IANAL, but I’m sure there are ways. Presumably, the next best thing would be like the couple who sued a bank that refused to pay up, so they eventually got bailiffs to come and start seizing computers and office furniture from one of the branches. Impound and auction off a couple of ICE vehicles?

The Constitution doesn’t offer much guidance.

I think if you were to ask the Framers, this is where they’d expect the people to rise up and depose the government. But, of course, the Framers would generally have expected a tyrant who tried to take the government by power, not by gaining popularity and using democratic systems to enforce rule over a minority that shuns weapons.

Of course, the Framers strongly opposed democratic systems so…whatever the outcome, IMHO, restoring some guardrails seems advisable.

As far as I can tell going back as far as 2016, he has never obeyed a court order and never suffered any consequences for it.

The first senate got sworn in somehow. They could probably find a magistrate somewhere to do it. (Coolidge was sworn in by his magistrate father).
