HOUSE BILL NO. ____ 
Introduced by HON. LUIS RAYMUND “LRAY” F. VILLAFUERTE, JR. 
AN ACT INSTITUTIONALIZING THE MANDATORY USE OF THE NAMES "WEST 
PHLIPPINE SEA" OR "KANLURANG DAGAT NG PILIPINAS" TO REFER TO 
THE MARINE AREAS ON THE WESTERN SIDE OF THE PHILIPPINES, AND FOR 
OTHER PURPOSES 
This proposed measure seeks to complement Administrative Order No. 29, Series of 
2012, and to further reinforce the Philippine's claim to the disputed islands found on 
the western side of the Philippine Archipelago through proper designation of the name 
“West Philippine Sea” or Kanlurang Dagat ng Pilipinas”. 
We have sovereign rights over our Exclusive Economic Zone (EEZ) for the purpose of 
exploring and exploiting, conserving and managing the natural resources. The EEZ is 
up to 200 nautical miles measured from the archipelagic baselines according to Article 
47 of the United Nations Convention on the Law of the Sea (UNCLOS). Moreover, 
based on the UNCLOS, the Philippines is granted a territorial sea of up to 12 nautical 
miles, a contiguous zone of up to 24 nautical miles. 
In view of the foregoing, the passage of this bill is earnestly sought.
