I think that’s incorrect, yeah. The SCOTUS painted “official acts” very, very broadly. More to the point though, SCOTUS put some strict limits on how one would prove they were unofficial acts.
Doesn't seem so broad to me.
“The President is not above the law,” Chief Justice John Roberts wrote for the conservative supermajority. “But Congress may not criminalize the President’s conduct in carrying out the responsibilities of the Executive Branch under the Constitution.”
The 6-3 ruling gave former presidents absolute immunity for duties within their core powers and some immunity for other official actions.
The president’s core constitutional powers include commanding the military, granting pardons, overseeing foreign relations, managing immigration, and appointing judges. Congress and the courts, Roberts wrote, cannot act or examine the president’s actions in this realm.
Roberts said that absolute immunity gets downgraded when the president’s actions fall outside those core areas.
“The reasons that justify the President’s absolute immunity from criminal prosecution for acts within the scope of his exclusive authority therefore do not extend to conduct in areas where his authority is shared with Congress,” Roberts wrote.
Then you have this hyperbole that implies a different understanding of presumptive immunity.
“Never in the history of our Republic has a President had reason to believe that he would be immune from criminal prosecution if he used the trappings of his office to violate the criminal law,” Sotomayor wrote. “Moving forward, however, all former Presidents will be cloaked in such immunity.”
In a separate dissent, Jackson said the court’s ruling broke new and dangerous ground, making the most powerful official in the American government exempt from criminal law.
