AN ACT
DECLARING THE MARITIME ZONES UNDER THE JURISDICTION OF 
THE REPUBLIC OF THE PHILIPPINES
EXPLANATORY NOTE
The Philippines has been a party to the United Nations Convention on 
the Law of the Sea (UNCLOS) and signed the same on 10 December 1982. The 
UNCLOS was a result of the desire to settle all issues relating to the law of the 
sea; to establish a legal order for the seas and oceans; and strengthen peace, 
security, cooperation and friendly relations among all conforming nations, 
just to cite a few, as enshrined in the preamble of the said Convention. It has 
since become the legal framework for marine and maritime activities
Section 2, Article II of the Constitution provides for an “incorporation 
clause”, which states that:
“The Philippines...adopts the generally accepted principles of 
international law as part of the law of the land...”
And this includes treaties, like the UNCLOS. While the UNCLOS is also 
considered as part of the law of the land, enacting a municipal law to this 
effect can further fortify the country’s claims over its maritime zones.
The proposed legislation seeks to declare and define the maritime zones 
under the jurisdiction of the Philippines. In this way, our country can further


preserve and protect our maritime rights. Likewise, just like the intention of 
the UNCLOS, this proposed bill may preclude any unwarranted and 
undesirable dispute with other nations involving our maritime areas. It also 
provides for the necessary flexibility in the passage of subsequent laws 
pertinent to the rights and obligations to which the Philippines is entitled and 
may exercise over its maritime zones.
In view of the foregoing, the immediate passage of this bill is earnestly 
sought.
