The Judiciary has no authority to override the president’s authority. That’s called separation of powers.

So when the courts struck down Obama's illegal DACA Executive Order, that was unconstitutional?

And they don’t have the authority to decide cases involving non U.S. citizens.

Article III, section 2 of the Constitution gives the federal courts jurisdiction over cases involving "foreign states, citizens or subjects."

Seems to me that the President does not legislate. His position is to ‘execute’ the executive function of the Executive branch and the law of the land as it was voted by Congress. Congress represents the will of the people.
Otherwise, our president will become a third world potentate and we a third world dictatorship.
