notifying the Court of it in July 2003. The case was heard at the Peace Palace in The Hague between 6 and 23 November 2007. The ICJ delivered its judgment on 23 May 2008. It held that although Pedra Branca had originally been under the sovereignty of Johor, the conduct of Singapore and its predecessors à titre de souverain (with the title of a sovereign) and the failure of Malaysia and its predecessors to respond to such conduct showed that by 1980, when the dispute between the parties arose, sovereignty over the island had passed to Singapore. The relevant conduct on the part of Singapore and its predecessors included investigating marine accidents in the vicinity of the island, planning land reclamation works, installing naval communications equipment, and requiring Malaysian officials wishing to visit the island to obtain permits. In contrast, Johor and its successors had taken no action with respect to the island from June 1850 for a century or more. In 1953 the Acting Secretary of the State of Johor had stated that Johor did not claim ownership of Pedra Branca. All visits made to the island had been with Singapore's express permission, and maps published by Malaysia in the 1960s and 1970s indicated that it recognised Singapore's sovereignty over Pedra Branca. Like Pedra Branca, the Sultan of Johor held the original ancient title to Middle Rocks. As Singapore had not exercised any rights as a sovereign over Middle Rocks, the ICJ determined that Malaysia retained sovereignty over this maritime feature. As for South Ledge, the ICJ noted that it fell within the apparently overlapping territorial waters of mainland Malaysia, Pedra Branca and Middle Rocks. As the Court had not been mandated to draw the line of delimitation with respect to the territorial waters of Malaysia and Singapore in the area in question, it simply held that sovereignty over South Ledge belonged to the state which owned the territorial waters in which it is located. Reactions to ICJ decision Although both Malaysia and Singapore had agreed to respect and accept the ICJ's decision, Malaysian Foreign Minister Rais Yatim later said his country had renewed its search for the letters written by Governor Butterworth to the Sultan and Temenggung of Johor seeking permission to build Horsburgh Lighthouse on Pedra Branca. He noted that the rules of the ICJ allowed a case to be reviewed within ten years if new evidence
