Parliament enacted the Constitution Twelfth Amendment Act 2005 and the Cross-Boundary Municipalities Laws Repeal and Related Matters Act 23 of 2005 to abolish cross-boundary municipalities and realign provincial boundaries. As a result, the Matatiele Local Municipality was transferred from KwaZulu-Natal to the Eastern Cape. Prior to this, the Minister of Provincial and Local Government had requested the Municipal Demarcation Board to re-determine Matatiele’s boundaries, but the Board proposed that Matatiele remain in KwaZulu-Natal. Parliament nevertheless proceeded with a constitutional amendment incorporating the Minister’s preferred outcome. The applicants, including the Matatiele Municipality and various community and business organisations, challenged the constitutional validity of the Twelfth Amendment and the Repeal Act, alleging that Parliament had unlawfully usurped the powers of the Municipal Demarcation Board and failed to follow constitutionally prescribed procedures.
