The decision means the federal election interference case against Trump will return to a lower court, which will then decide how to apply the Supreme Court ruling.
While the court ruled that the former president is immune from criminal prosecution for "official acts" taken in office, he is not immune for "unofficial acts".
Writing the court's opinion, Chief Justice John Roberts said: "The nature of Presidential power entitles a former President to absolute immunity from criminal prosecution" for official acts taken as president. The document stipulates that courts would need to distinguish between what were official and unofficial actions.
