evidence: On 21 December 1979, Malaysia published a map that showed the island to be within its territorial waters. This ignited a 29-year territorial dispute which, together with the issue of sovereignty over the nearby maritime features of Middle Rocks and South Ledge, the disputants presented to the International Court of Justice (ICJ) for resolution. On 23 May 2008, the ICJ ruled that Pedra Branca was under Singapore's sovereignty. At this point, the ICJ also noted Singapore's plans to conduct reclamation at Pedra Branca.[2] Although the island had originally been under the sovereignty of the Johor Sultanate, the United Kingdom and Singapore had carried out various acts of sovereignty in respect of the island. The failure of Malaysia and its predecessors to respond to these acts, and other actions that demonstrated their acknowledgment of Singapore's sovereignty over the island, meant that Singapore had gained sovereignty over Pedra Branca. On the other hand, Middle Rocks remain part of Malaysian territory as Singapore had not manifested any acts of sovereignty in respect to it. The Court did not rule definitively on the remaining outcrop, South Ledge, declaring that it belonged to the state in the territorial waters of which it is located.
