China says it has no intention of participating in the case, which it has called an attempt by Manila to legalize its occupation of Chinese islands in the South China Sea.
Overlapping claims in the South China Sea - traversed by half the world's shipping tonnage - are one of the region's biggest flashpoints amid China's military build-up and the U.S. strategic "pivot" back to Asia.
The claims of the Philippines, Vietnam, Malaysia and Brunei are bisected by China's "nine-dash line" - the historic claim that reaches deep into the maritime heart of Southeast Asia.
Del Rosario also accused China of violating international laws and a non-binding pact in the South China Sea between China and 10 smaller Southeast Asian states, after sending ships to the Scarborough and Second Thomas Shoals.
