Judgment No. CCZ 4/15 7 Civil Appeal No. CCZ 27/13 (17) Section 43 on the other hand provides that every person who before 22 May 2013 was a citizen continues to be one after that date. It also provides that any person who was born in Zimbabwe before 22 May 2013 is a citizen by birth if one or both of his parents was a citizen of a SADC member State and he or she was ordinarily resident in Zimbabwe as at that date. INTERPRETATION OF THE CONSTITUTION (18) Section 2 of the Constitution provides that the Constitution is the Supreme law of the land and that any law, practice, custom or conduct inconsistent with it, is invalid to the extent of the inconsistency. It also provides that the obligations imposed by the Constitution are binding on every person, including the State and all its organs at every level. (19) This section is important as it stipulates beyond doubt that anything done contrary to the provisions of the Constitution is invalid. (20) Various decisions of this Court and elsewhere have made pronouncements on the correct approach to the interpretation of a Constitution. 20.1 In Rattigan & Others v Chief Immigration Officer & Others 1994(2) ZLR 54(S), 57, GUBBAY CJ remarked: “What is to be avoided is the imparting of a narrow, artificial, rigid and pedantic interpretation; to be preferred is one which serves the interest of the Constitution and best carries out its objects and promotes its purpose. All relevant provisions are to be considered as a whole and where rights and freedoms are conferred on persons, derogations therefrom, as far as the language permits, should be narrowly and strictly construed.”
