BUT... Impeachment: Congress has the constitutional power to impeach and remove a president from office for "high Crimes and Misdemeanors," which would include deliberately ignoring the Supreme Court. If removed, a former president could then face criminal prosecution.
WISH IT WAS TRUE BUT IT'S NOT - Contempt: A court can issue a contempt ruling against the president's administration or other officials, potentially imposing fines on the government. However, the president cannot be held in contempt for ignoring injunctions against the federal government.
