evidence: The Scarborough Shoal, a triangular coral reef formation which surrounds a lagoon, is famed for its rich waters and marine resources. It is located 124 nautical miles off Masinloc, Zambales, and is considered within the Philippines’ 200-nautical mile exclusive economic zone, based on the 1982 United Nations Convention on the Law of the Sea (UNCLOS). [...] For retired Supreme Court Associate Justice Antonio Carpio, the shoal has been in the territory of the Philippines since 1734, when it was called "Panacot." "The official maps of the Philippine territory during the Spanish regime, starting from 1734, 1808, until 1875, that’s just a few years before the Paris Treaty of 1898, all show that Scarborough Shoal is part of Philippine territory," Carpio said.
