By virtue of section 42(2) of the Laws of Tuvalu Act 1987, the Law of Tuvalu includes
customary law. Schedule 1 paragraph 3 and 4 of the Laws of Tuvalu Act 1987 require that courts must take customary law into account when considering specified matters in criminal and civil proceedings. The law that existed at the time of independence is preserved in Schedule 5 sections 1 and 2 of the Constitution as “any Acts of the Parliament of the United Kingdom, Orders of Her Majesty in Council, Ordinances, rules, regulations, orders or other instruments having effect as part of the law of Tuvalu”, subject to these laws not being in conflict with any provisions in the Constitution. This provision is reinforced by the Laws of Tuvalu Act 1987: “An Act to declare what constitutes the Laws of Tuvalu”. Section 4 of the Laws of Tuvalu Act 1987 describes the laws as being derived from: the Constitution, the law enacted by the Parliament of Tuvalu, customary law, the
common law of Tuvalu and every applied law. ‘Applied law’ is defined in section 7 of that Act as “imperial enactments which have effect as part of the law of Tuvalu”. ==Imperial enactments==
