Twenty-second Amendment to the United States Constitution

Powers of the President of Singapore
The original Article 22H of the Constitution provided the President with personal discretion to withhold assent to any bill (other than a bill to which Article 5(2A) applies) which provided directly or indirectly for the circumvention or curtailment of the discretionary powers conferred upon the President by the Constitution. At that time, Article 5(2A) provided that the President could prevent Parliament from passing a bill seeking to amend certain specified clauses of the Constitution, including those dealing with the President's powers, unless it had been supported by not less than two-thirds of the votes cast at a national referendum. However, as Article 5(2A) was not yet in force, a question arose as to whether the Government was entitled to amend the Constitution in a way that circumvented or curtailed the President's discretionary powers, or whether Article 22H prohibited this entirely.
