NRS 315.650

If any of the commissioners or officers of the authority whose signatures appear on any bonds or coupons cease to be such commissioners or officers before the delivery of such bonds, such signatures shall, nevertheless, be valid and sufficient for all purposes, the same as if such commissioners or officers had remained in office until such delivery. Any provision of any law to the contrary notwithstanding, any bonds issued pursuant to NRS 315.140 to 315.7821, inclusive, are fully negotiable.
