When the referendum passed and the final certificate has issued, the amendment must be signed into law by the President "forthwith". Provided that the correct procedure has been complied with, the President cannot veto an amendment. The dates given for the amendments listed in this article are, unless otherwise stated, the dates on which they were signed into law. The shortest gap between the referendum and signing into law was twelve days for the 18th, 19th and 20th amendments. The longest was 899 days for the 31st amendment. No referendum has ever been annulled by the courts.
