The Supreme Court decision on former president Donald Trump’s claims of presidential immunity has been seen by many as one of the most consequential rulings in the history of the high court. The justices decided 6-3 along ideological lines that presidents are immune from criminal prosecution for “official acts,” while adding that they may still be prosecuted for unofficial acts. The ruling did not offer a clear line between the two, and the justices may have to settle further disputes about that — including in Trump’s four criminal cases.
