News flash. You don't need to dissolve the judiciary. You just need to make them compliant to the autocrat. And it doesn't matter if the front line judges stick with the long established precedents. The USSC can break the precedent.

Yes, you need to dissolve the existing judiciary, because an independent judiciary will not be "compliant" enough. To rule like Marcos, Trump can't have a judiciary that just "leans" towards supporting his Administration's interpretations on open questions of law. He needs one that's willing to essentially hold that "even though X violates the Constitution, Trump should be allowed to do X." I don't think any of the existing Justices would do that now. The older ones certainly have no reason to do anything that Trump wants that they don't also want, and the younger ones will be on the court long after Trump is gone.

Dictators can't have a situation where there's an independent judiciary with judges that don't depend on him for their position - because those people can say "no" to the dictator.
