The applicants, representing the Moutse community in Mpumalanga Province, challenged the constitutional validity of the Constitution Twelfth Amendment Act of 2005 and the Cross-Boundary Municipalities Laws Repeal and Related Matters Act. These laws abolished cross-boundary municipalities and relocated certain areas, including Moutse 1 and Moutse 3, from Mpumalanga to Limpopo Province. Cross-boundary municipalities had been difficult to administer, with different provincial legislation applying to the same municipality. The Moutse community had a history dating to 1780, was predominantly Sepedi-speaking, and had in 1996 agreed with government to remain in Mpumalanga rather than move to Gauteng. The relocation was effected to place the entire Greater Sekhukhune District Municipality within one province (Limpopo). The Mpumalanga Provincial Legislature held public hearings on the Amendment Bill, including hearings at Greater Tubatse on 28 November 2005 (for Moutse 1) and at Dennilton on 8 December 2005 (for Moutse 3, after community protest). The Legislature approved the Bill on 12 December 2005. The applicants launched this challenge over two years after the Amendment came into force.
