The Insurance Code during the Marcos period was promulgated under Presidential Decree 612. Presidential Decree 612 was amended by Presidential Decrees 1141, 1280, and 1455. The Insurance Code supposedly was revised under Presidential Decree 1460 (The attachment thereto [or the copy of the alleged revision] is not usually available online, if it exists). Presidential Decree 1460 was amended by Presidential Decree 1814 and Batas Pambansa 847 (Presidential Decree 1814 is one of the Presidential Decrees in question under the landmark case of Tanada v. Tuvera, GR L-63915, 24 April 1985 [Decision] and 29 December 1986 [Resolution], and it remains a question whether such laws and issuance were subsequently published, as government promulgations online are not consistent in the details as to where and when such laws have been published. Whether they were actually published would be a matter that would need verification).
Republic Act 10607 was promulgated on 15 August 2013 and was meant to revise the Insurance Code of the Philippines. It referred to a revision of Presidential Decree 612 and not 1460.
Reading the revisions made by Republic Act 10607, in one legal document, is convenient for many, while further piecemeal amendments thereto are not yet present. For someone who has read the Insurance Code or has studied it, the absence of indications of which parts have been amended or merely renumbered provides an additional task in determining the same. This is quite important as legal literature may have expounded matters relevant to the provisions, and the verification task is necessary so as to reuse prior literature for provisions which were not modified, else merely renumbered. Considering that the old law provides for 424 sections, and the new law provides 448 sections, the act of verification takes time.
To help reduce the redundancy of efforts to verify the same, here is a list to determine the changes, whether substantial or not.
