EXPLANATORY NOTE 
Article I of the 1987 Philippine Constitution declares that: 
"The national territory comprises the Philippine archipelago, with all the islands and 
waters embraced therein, and all other territories over which the Philippines has 
sovereignty or jurisdiction, consisting of its terrestrial, flUvial and aerial domains, 
including its territorial sea, the seabed, the subsoil, the insular shelves, and other 
submarine areas. The waters around, between, and connecting the islands of the 
archipelago, regardless of their breadth and dimensions, form part of the internal waters 
of the Philippines. " 
Pursuant to the 1982 United Nations Convention on the Law of the Sea (UNCLOS), of which the 
Philippines is a signatory and a party, our country and other coastal States has been recognized to 
have the right to establish various maritime zones and jurisdictions over which sovereignty and 
appurtenant sovereign rights can be exercised. Given the premise, this bill seeks to have a 
general declaration and definition of the maritime zones under the jurisdiction of the Philippines. 
This proposed legislation has the aim of preserving and protecting the country's maritime rights, 
as it mentions in general terms the rights that the Philippines may exercise over its maritime 
zones. 
Establishing the extent of the limits of the maritIme zone of the Philippine archipelago 
practically averts any unnecessary dispute with vessels of foreign states entering the Philippine 
maritime territory without our permission. 
Hence, the approval of this bill is earnestly requested.
