After years of negotiations, the Philippine government and the Moro Islamic Liberation Front signed the Comprehensive Agreement on the Bangsamoro (“CAB”) on 27 March 2014 that seeks to end more than four decades of Muslim secessionist movements and violence in Mindanao. The CAB includes the Framework Agreement on the Bangsamoro earlier signed on 15 October 2012, the four annexes (normalization, revenue generation and wealth sharing, transitional arrangement and modalities), and other agreements signed by both parties during the course of the 17-year peace negotiations. Despite the assurance by the negotiating parties of its constitutionality, the Bangsamoro Basic Law ("BBL") bill is expected to encounter severe scrutiny in Congress. As soon as the BBL becomes law, its constitutionality or other legally controversial provisions will most likely be challenged before the Supreme Court. When the dust has settled, the Bangsamoro governance structure will surely pave the way for the region to realize its full economic and development potential utilizing the untapped mineral and energy resources.
