Publication of Laws for Effectivity

Section 1 requires that laws take effect after fifteen days following the completion of their publication.
Section 1 provides that publication must be made either in the Official Gazette or in a newspaper of general circulation in the Philippines.
Section 1 applies the 15-day rule unless the law itself otherwise provides for a different effectivity.
Section 1 governs the effectivity timing measured from the completion of the required publication.

Section 2 amends Article 2 of Republic Act No. 386, otherwise known as the Civil Code of the Philippines.
Section 2 repeals or modifies all other laws inconsistent with Executive Order No. 200.
Section 2 specifically changes the rule from requiring publication in the Official Gazette alone to requiring publication either in the Official Gazette or in a newspaper of general circulation in the Philippines.

Executive Order No. 200 is grounded on Article 2 of the Civil Code and recognizes that the prior rule on publication in the Official Gazette alone created practical problems.
Executive Order No. 200 cites the Supreme Court decision in Tañada, et al. v. Tuvera, et al. (G.R. No. 63915, December 29, 1986) as an acknowledgment of issues affecting Official Gazette publication and the need for broader communication.
Executive Order No. 200 states that newspapers of general circulation can communicate laws to the people more effectively due to wider readership and regular publication.
Executive Order No. 200 therefore aligns the effectivity requirement with publication in either the Official Gazette or a newspaper of general circulation.

Section 1 functions as the operative rule for the effectivity of laws: publication completion plus 15 days, unless otherwise provided.
Section 2 operates immediately to repeal or modify inconsistent provisions governing publication-based effectivity.
Executive Order No. 200 is implemented as a rule on how laws become effective through publication.
Executive Order No. 200 contains no separate administrative implementing mechanism beyond its directive on publication and effectivity.
