use it as fishing ground and have always considered it their own.[30]

The DFA also claims that the name Bajo de Masinloc (translated as "under Masinloc") itself identifies the shoal as a particular political subdivision of the Philippine Province of Zambales, known as Masinloc.[30] As basis, the Philippines cites the Island of Palmas Case, where the sovereignty of the island was adjudged by the international court in favor of the Netherlands because of its effective jurisdiction and control over the island despite the historic claim of Spain. Thus, the Philippines argues that the historic claim of China over the Scarborough Shoal still needs to be substantiated by a historic title, since a claim by itself is not among the internationally recognized legal basis for acquiring sovereignty over territory.

It also18th and 20th centuries show Scarborough Shoal as Philippine territory. The 18th-century map "Carta hydrographica y chorographica de las Islas Filipinas" (1734) shows the Scarborough Shoal then was named as Panacot Shoal. The map also shows the shape of the shoal as consistent with the current maps available as today. In 1792, another map drawn by the Malaspina expedition and published in 1808 in Madrid, Spain also showed Bajo de Masinloc as part of Philippine territory. The map showed the route of the Malaspina expedition to and around the shoal. It was reproduced in the Atlas of the 1939 Philippine Census, which was published in Manila a year later and predates the controversial 1947 Chinese South China Sea Claim Map that shows no Chinese name on it.[37] Another
