AN ACT 
RENAMING THE BENHAM RISE AS "PHILIPPINE RISE" OR "TALAMPAS NG 
PILIPINAS," NAMING THE UNDERSEA FEATURES THEREIN, AND FOR OTHER 
PURPOSES 
On May 6, 2017, President Rodrigo Duterte issued Executive Order No. 25 renaming 
Benham Rise to "Philippine Rise". The Philippine Rise is a 13-million-hectare 
underwater plateau, largely unexplored, and is said to be larger than Luzon with 
potentially rich deposits of natural gas and other resources such as heavy metals. 
The Philippines submitted its claim for an extended continental shelf in the Philippine 
Rise Region to the United Nations Commission on the Limits of the Continental Shelf 
(UNLCS) in 2009. The UNCLCS confirmed the Philippine Rise as part Philippines' 
extended continental shelf in 2012. 
This bill seeks to solidify the sovereign will of the people by renaming, through 
legislative fiat, the Benham Rise as "Philippine Rise" or "Talampas ng Pilipinas" 
amidst competing maritime claims in the West Philippine Sea.  
In view of the foregoing, the immediate passage of this bill is earnestly sought.
