1.4 The constitutional validity of the Twelfth Amendment and the Repeal Act was challenged in the Constitutional Court. On 18 August 2006 the Constitutional Court, in Matatiele Municipality and Others v President of the Republic of South Africa and Others 2007 (1) BCLR 47 (CC) (the Matatiele case), declared that part of the Twelfth Amendment which effectively relocated the Matatiele municipality to the province of the Eastern Cape to be inconsistent with the Constitution and therefore invalid. The order of invalidity was based on a procedural defect, namely the failure of the KwaZulu-Natal provincial legislature to facilitate public involvement, as required by section 118(1)(a) of the Constitution, when it considered whether or not to approve that part of the Constitution Twelfth Amendment Bill of 2005 that effectively relocated the Matatiele municipality from the province of KwaZulu-Natal to the province of the Eastern Cape. As a result of the interrelationship between the Twelfth Amendment and the Repeal Act, the Court also declared that part of the Repeal Act which relates to the Matatiele municipality to be inconsistent with the Constitution and therefore invalid. The orders of invalidity were suspended for a period of 18 months, during which period Parliament has the opportunity to correct the constitutional defect that led to the orders of invalidity.
