72. The President has the right to suspend the proclamation of a law for a period of two months. The President shall suspend the proclamation of a law if so requested by not less than one-third of the members of the Saeima. This right may be exercised by the President, or by one-third of the members of the Saeima, within ten days of the adoption of the law by the Saeima. The law thus suspended shall be put to a national referendum if so requested by not less than one-tenth of the electorate. If no such request is received during the aforementioned two-month period, the law shall then be proclaimed after the expiration of such period. A national referendum shall not take place, however, if the Saeima again votes on the law and not less than three-quarters of all members of the Saeima vote for the adoption of the law.
