PERSONS & FAMILY RELATIONS REVIEWERARTICLE 2: Effectivity of Law-Law will take effect base on the provision of thelaw itself.-When it provides for its own effectivity: itbecomes effective of the specific date, as long asit has been published.-Then apply Article 2 which provides that lawshall take effect after 15 days following thecomplete publication in the official gazette ornewspaper of general circulation unlessotherwise provided.-What is indispensable, however is thepublication regardless the kinds of laws that hasbeen passed by the congress, even if the law thatwould only benefit a specific person as long as itis a law, then it has to be published to beeffective otherwise it will run counter to that dueprocess clause of the constitution.-“unless otherwise provided”refers to theeffectivity of the law precisely if the law itselfprovides for its own effectivity then it becomeseffective – for as long as it has been publishedwith what is mandatory in the compliance withthe requirements of publication. -Under the case of Tanada vs. Tavera, this refersto several laws that were passed during the timeof former President Marcos which were notpublished but were given effect and thus whenCory Aquino assumed office this was questionedbefore the Supreme Court. The Supreme Courtsaid that all laws, presidential decrees, executiveorders, as well as other laws that were notpublished are considered without any effectwhatsoever likewise it also made mention of alllaws that must be published for its effectivity butnot when we speak of the decisions of theSupreme Court. Decisions of the Supreme Courtare not laws, they merely serve in relation toArticle 8 to interpret and apply the provisions ofthe law and the Constitution. While it may betrue that it forms part of the judicial system ofthe Philippines, however, they are not laws, theymerely serve to interpret the law or theConstitution.-In the case of De Roy v. CA, the Court said, it’snot the duty of the Supreme Court to publishjudicial decisions rather it is the bounded duty ofthe lawyer to be abreast to the latest decisions ofthe Court.CASES under Article 2TANADA v TUVERA, 136 SCRA 27 April 24, 1985FACTS: The PETITIONERS, Tanada et al, seek a writ ofmandamus to compel RESPONDENTS to publish, and/orcause the publication of various presidential issuances byinvoking the people’s right to be informed under theConstitution as well as the principle that laws to be validand enforceable must be published in the Official Gazetteor otherwise effectively promulgated.
