Following the enactment of Republic Act No. 9522 or the Archipelagic
Baselines Act in May 2009 and the Supreme Court ruling in 2011 upholding its
constitutionality, there was a push to further strengthen the domestic legal
framework with respect to the nation’s territory and maritime entitlements. The
ruling also recognized RA 9522 as an important tool and starting point to demarcate
and protect the country’s maritime zones and continental shelf under UNCLOS.
