History of Singapore
During World War 2, Singapore was conquered and occupied by the Japanese Empire from 1942 to 1945. When the war ended, Singapore reverted to British control, with increasing levels of self-government being granted, culminating in Singapore's merger with the Federation of Malaya to form Malaysia in 1963. However, social unrest and disputes between Singapore's ruling People's Action Party and Malaysia's Alliance Party resulted in Singapore's expulsion from Malaysia. Singapore became an independent republic on 9 August 1965.
Supreme Court of Singapore
During the Japanese occupation of Singapore (1942–1945), all the courts that had operated under the British were replaced by new courts established by the Japanese Military Administration. The Syonan Koto-Hoin (Supreme Court) was formed on 29 May 1942; there was also a Court of Appeal, but it was never convened. Following the end of World War II, the courts that had existed before the war were restored. There was no change in the judicial system when the Straits Settlements were dissolved in 1946, and Singapore became a crown colony in its own right, except that the Supreme Court of the Straits Settlements became known as the Supreme Court of Singapore.
