Singapore is city-state located in Southeast Asia. Its strategic location in the Malay Archipelago was one of the major attractions for British colonists, who founded modern Singapore in 1819 as a trading port on the India-China trade route. The country went on to become a British Crown Colony, become a component state of the Federation of Malaysia in 1963, and gain full independence in 1965. The four official languages are Malay, Mandarin, Tamil, and English.

Singapore's history and constitutional make-up is predominantly British in influence with a unitary, multiparty, Westminster system of parliamentary government and a legal system based on English common law. The Singaporean legal system also occasionally draws from other sources: its Codes, for example, were borrowed from India in the nineteenth century and some areas, such as land registration and company law, draw more from Australian rather than British models.

IALS Library has a good selection of primary and secondary Singaporean materials at IALS Library, which can be found at the classmark GM4n (Straits Settlements) and GM4m (modern Singapore).


1819-1942 Straits Settlements

Sir Stamford Raffles arrived in Singapore in January 1819 and quickly realised its advantageous location as a British port in the Malay Archipelago. On 6 Feb 1819 the British signed the Treaty of Friendship and Alliance, establishing the British East India Company trading post on Singapore, and then the Treaty of London (or Anglo-Dutch Treaty) in 1824, which gave full sovereignty and property in Singapore to the English East India Company. 

In 1826 the Straits Settlements were established in order to amalgamate the British territories of Singapore, Malacca and Penang and to further clarify borders between British land and other occupied territories in the area.

During this period, English law was loosely administered in the Settlements through the Resident's Court, and regulations were set down by Raffles in 1823 (reprinted in Malaya Law Review [1968] 10 248 - GM4.J.2). These regulations were largely followed until 1827. By this time, the Second Charter of Justice had established the Court of Judicature for Prince of Wales Island (Penang), Malacca and Singapore, bringing English common law to the Straits Settlements. However, there were significant administrative and financial problems and the Court of Judicature had no law-making ability, with the British government legislating from Calcutta. Until 1856 the judicial headquarters of the Straits Settlements was in Penang.

On 1 Apr 1867, the British government designated the Straits Settlements a Crown Colony, meaning that the countries in the Settlement received orders directly from the Colonial Office in London rather than from India. Singapore was appointed a Governor with legislative and executive councils. The Court of Judicature was also abolished and replaced by the Straits Settlements Supreme Court.

This structure remained largely unchanged for the next 75 years until the Second World War.

1942-1945 Japanese Occupation

The Japanese invaded Singapore in February 1942 and for the first four months all courts were shut down and the Military Court of Justice of the Nippon Army was established. During this period, however, there was confusion as to who had proper legislative authority and on 27 May 1942 the civil courts reopened and former British laws were administered as long as they did not interfere with the Military Administration. The fact that the Japanese did not make significant constitutional changes made it easy for the British to re-establish pre-war legal structures after the war.

1946-1958 Colony of Singapore

Between September 1945 and April 1946, Singapore operated under the British Military Administration (BMA), which saw all laws prior to Japanese Occupation brought back into force. The Straits Settlements were abolished and Singapore became its own Crown Colony with its own constitution. The Straits Settlements Supreme Court was replaced by the Supreme Court of the Colony of Singapore.

On 1 March 1948 a new constitution came into effect and elections were held for the first time.

British Parliament passed the State of Singapore Act on 1 Aug 1958, making the Colony a self-governing state. The post of Governor was abolished and replaced by Yang di-Pertuan Negara (Head of State) who could invite the winning party to form a government, thus establishing a Westminster Cabinet system of government. 

1963-1965 Merger & Independence

Singapore became a member of the Federation of Malaysia in 1963, which was thought to benefit the economy by creating a common, free market, and to improve Singapore's internal security. While Singapore was part of Malaysia, the judicial system was a typical hierarchical structure consisting of lower courts, a High Court and a Court of Appeal. The High Court of Malaysia in Singapore replaced the old Supreme Court of the Colony of Singapore, with sister high courts in Malaya and Borneo and a Federal Court presiding over all.

Singapore separated from the rest of Malaysia on 9 August 1965 and Singapore became independent. At independence, Singapore retained the court structure of the Federation of Malaysia, and the Singapore High Court remained under the umbrella of the Federal Court until the Constitution Amendment Act (1969).

After gaining independence in August 1965 Singapore was free to begin creating its own constitution. Between 1965 and 1980 a makeshift constitution existed, combining the Constitution of the State of Singapore (1963), the Republic of Singapore Independence Act (1965) and certain provisions from the Malaysian Federal Constitution. In 1980 these three documents were consolidated into the 1980 Reprint of the Constitution of the Republic of Singapore.

The constitution is the supreme law of the land and lays down the fundamental principles and basic framework of state organisation. The Singaporean legal structure is premised on constitutional supremacy which, in theory, means that the law-making powers are limited by the constitution and judges can if necessary strike down both legislative and executive acts as being unconstitutional (although this power is very rarely used by judges in Singapore).

The 1980 Reprint of the Constitution of the Republic of Singapore is available at IALS Library in hard copy at GM4m.C.1 AAA1.  

World Constitutions Illustrated, available on the database HeinOnline, is a good source for constitutions, both current and previous versions. The Constitution of the Republic of Singapore can be found here, along with its amendments and amending laws. HeinOnline is available onsite to academic users and remotely for University of London staff and students with a valid IALS Library card.

Singapore Statutes Online (SSO) provides an open access copy of the Constitution, with amendment notes. 


The highest court is the Supreme Court, which consists of the Court of Appeal, Appellate Division of the High Court, the General Division of the High Court and the Singapore International Commercial Court. The Supreme Court hears civil and criminal cases.

The State Courts (formerly Subordinate Courts) consist of the District Courts, Magistrates' Courts, Coroners' Courts, Small Claims Tribunals, Community Disputes Resolution Tribunals and Employment Claims Tribunals. They hear civil and criminal matters.

The Family Justice Courts consist of the Family Courts, Your Courts and the Family Division of the Hight Court. They hear family cases and selected cases involving youth offenders.

More detailed information about the court structure can be found on the GlobaLex website and on the website of the Singapore Singapore Courts website.

Sources of primary legislation in print

Modern Acts are contained in the publication The statutes of the Republic of Singapore (1986). This looseleaf is available at IALS at GM4m.E.1 (the last update was in 2007). A previous edition (1970) is available at RES GM4m.E.1. The chapters in the 1986 revised edition were entirely renumbered so there is no continuity or connection with the numbering of laws in the previous (1970) edition. These works were preceded by the following previous revised editions, available at IALS:

  • Laws of the Straits Settlements: revised edition 1936 (covers 1835-1935) RES GM4n.E.1

The official text of Singapore legislation is the published version in the Government Gazette or that ordered from the Singapore Government Printer which is published weekly on Friday. There is a daily online version of the Gazette, the eGazette which is available for free, but be aware that printouts from the site are not considered as a copy of the Gazette printed by the Government Printer for the purposes of S48 of the Interpretation Act.
