The Supreme Court will issue the final opinions of its terms on Monday.

Chief Justice John Roberts made the courtroom announcement on Friday. Four cases remain to be decided, including whether former President Trump has immunity from prosecution.

Trump is arguing that former presidents are immune from prosecution for official acts they took in office and that the indictment he faces on charges of election interference must be dismissed.

The Supreme Court has previously ruled that former presidents can’t be sued in civil cases for what they did in office, but it has never weighed in on criminal immunity.

The timing of the decision may be as important as the outcome. Trump’s trial in Washington, D.C., may not take place before the November election, even if the court rules he is not immune.
