Retired Supreme Court Senior Associate Justice Antonio T. Carpio is calling for a new international arbitration case to address sovereignty issues in the West Philippine Sea — particularly over the Kalayaan Island Group.
In a recent interview, Carpio pointed to centuries-old Philippine maps — including the 1734 Murillo Velarde map — as historical proof of the country’s longstanding claim. He emphasized that arbitration is not hostility, but a legitimate diplomatic tool grounded in international law.
The Philippines won in 2016.
Can it prevail again?
