Absolutely. They can’t amend the Constitution through ordinary means. Which is why they’ve installed a bunch of extreme right-wing Supreme Court justices who can interpret the Constitution however they want to benefit right-wing extremists.

Here’s a completely plausible scenario: Donald Trump orders ICE to deport any child born here to non-citizen parents in complete defiance of the court order. The district court judge gets really annoyed and issues criminal contempt rulings against the head of DHS and ICE for disobeying an order of the court. Trump orders DHS and ICE to ignore the court and promises pardons to anyone facing criminal contempt charges.

Because the SCOTUS has ruled “core powers” are “absolutely immune” and the pardon is an explicit power granted to the president with no limitations, he can use the pardon power literally however he wants, including as part of a criminal conspiracy to break the law.

And bam, full blown constitutional crisis because the SCOTUS basically neutered the entire judicial branch and gave the president dictatorial powers.
