Don't worry, they effectively ruled it's okay as a hobby as well by gutting the Chevron defense last week to kneecap the EPA and every major federal agency.
Would it be illegal for Biden to invalidate every ruling this Court has made, including the Presidential immunity one? Or would that lead to a paradox?
The ruling on presidential immunity today was pretty paradoxical, he has criminal immunity to breaking the law if he argues it's "to take care that laws be faithfully executed." Absolute immunity even since that's right in article 2, so why not?
