Cruz v. Paras, 123 SCRA 569 (1983) F: The petitioners are operators or nightclubs in Bocaue, Bulacan. they filed prohibition suits to stop the Mun. of Bocaue from enforcing an ordinance prohibiting the operation of nightclubs, cabarets, and dance h alls in that mun. or the renewal of licenses to operate them. The CFI upheld the validity of the ordinance and dismissed the petition. Hence, this petition for certiorari. HELD: A mun. corp. cannot prohibit the operation of nightclubs. Nightclubs may be regulated but not prevented from carrying on their business. RA 938, as orginally enacted, granted municipalities the power to regulate the establishment, maintenance and operation of nightclubs and the like. While it is true that on 5/21/54, the law was amended by RA 979 w/c purported to give municipalities the power not only to regulate but likewise to prohibit the operation of nightclubs, the fact is that the title of the law remained the same so that the power granted to municipalities remains that of regulation, not prohibition. To construe the amendatory act as granting mun. corporations the power to prohibit the operation of nightclubs would be to construe it in a way that it violates the constitutional provision that "every bill shall embrace only one subject which shall be expressed in the title thereof." Moreover, the recentyly-enacted LGC (BP 337) speaks simply of the power to regulate the establishment, and operation of billiard pools, theatrical performances, circuses and other forms of entertainment. Certiorari granted
