The Supreme Court highlights that a former president can face criminal prosecution for unofficial acts during his time in office. However, due to the separation of powers, there is a recognized need for a level of immunity for a president's official acts to prevent hindrance in the exercise of constitutional powers. The Court suggests that while some immunity must be absolute for core presidential powers, the extent of immunity for other official actions remains under consideration. Immunity is crucial to allow the president to make decisions based on public interest without fear of future legal consequences that may impede presidential functions.
