The legal system of Singapore is based on the English common law system. Major areas of law – particularly administrative law, contract law, equity and trust law, property law and tort law – are largely judge-made, though certain aspects have now been modified to some extent by statutes. However, other areas of law, such as criminal law, company law and family law, are almost completely statutory in nature.
Apart from referring to relevant Singaporean cases, judges continue to refer to English case law where the issues pertain to a traditional common-law area of law, or involve the interpretation of Singaporean statutes based on English enactments or English statutes applicable in Singapore. These days, there is also a greater tendency to consider decisions of important Commonwealth jurisdictions such as Australia and Canada, particularly if they take a different approach from English law.
Certain Singapore statutes are not based on English enactments but on legislation from other jurisdictions. In such situations, court decisions from those jurisdictions on the original legislation are often examined. Thus, Indian law is sometimes consulted in the interpretation of the Evidence Act (Cap. 97, 1997 Rev. Ed.) and the Penal Code (Cap. 224, 2008 Rev. Ed.) which were based on Indian statutes.
