The Pedra Branca dispute was a territorial dispute between Singapore and Malaysia over several islets at the eastern entrance to the Singapore Strait, namely Pedra Branca, Middle Rocks and South Ledge. The dispute began in 1979 when Malaysia published a map claiming Pedra Branca. In 1989, Singapore proposed submitting the dispute to the International Court of Justice and Malaysia agreed to this in 1994.
The hearing before the ICJ was held over three weeks in November 2007. Eventually, on 23 May 2008, the Court ruled that Pedra Branca is under Singapore's sovereignty, while Middle Rocks belongs to Malaysia. It also ruled that South Ledge belongs to the state in the territorial waters of which it is located, as it is a maritime feature visible only at low tide. Malaysia and Singapore have established what they have named the Joint Technical Committee to delimit the maritime boundary in the area around Pedra Branca and Middle Rocks, and to determine the ownership of South Ledge.
