The Constitution of Singapore is the supreme law of Singapore. Ordinary laws that were in force prior to the Constitution coming into force on 9 August 1965 continue to apply after the Constitution's commencement but must be construed with such modifications, adaptations, qualifications and exceptions as may be necessary to bring them into conformity with the Constitution. Any law enacted by the Legislature after the commencement of the Constitution which is inconsistent with the Constitution is void to the extent of the inconsistency. Thus, the Constitution reflects the principle established in the landmark decision of the Supreme Court of the United States, "Marbury v.
