What laws should be published?

Article 2. Laws shall take effect after fifteen (15) days following the completion of their publication in the Official Gazette, unless it is otherwise provided. This Code shall take effect one year after such publication. (New Civil Code of the Philippines)

The above provision of law applies to the effectivity of ordinary laws and the New Civil Code itself. READ: RA, BP, EO, ETC. WHY DIFFERENT NAMES FOR LAWS?

It must be noted that, when a country is placed under martial law, the law-making authority is ordinarily vested in the Chief Executive or President or the Commander-in-Chief who is usually given the power to issue: general orders; presidential decrees or executive orders; letters of instruction or letters of implementation; and proclamations.

General orders are similar to codes. Presidential decrees or executive orders are similar to statutes. Letters of instruction or letters of implementation are similar to circulars. Proclamations are announcements of important things or events. READ: "NOTES ON ARTICLE 2: PUBLICATION OF LAWS."
