2. Sandy Cay was extensively discussed in the final ruling of the arbitral tribunal dated 12 July 2016. Sandy Cay is located between Pag-asa and Subi Reef, although much closer to Pag-asa. Sandy Cay is a disappearing high-tide sandbar – it appears for a few months and then disappears, and then re-appears again either in the same place or in a nearby place. The disappearance is caused by storms which disperse the sand. The action of the waves reforms the sandbar after a few months and thus the sandbar re-appears again. The arbitral tribunal did not deem it necessary to decide whether Sandy Cay is a high-tide or low-tide elevation because there are low-tide elevation rocks in the Pagasa Reef between Pag-asa and Subi Reef that could be used as baselines of Pag-asa even without Sandy Cay. These rocks, as baselines, extend the territorial sea of Pag-asa to include Subi Reef which is a low-tide elevation forming part of the continental shelf of the Philippines.
