The City of Cape Town, formed in 2000 through municipal amalgamation, implemented a uniform system of charging for sewerage services and refuse removal across its jurisdiction. From 1 July 2002 and more significantly in the 2003/2004 financial year, the City imposed charges partly based on consumption and partly calculated with reference to the municipal value of properties. These value-based charges, effectively levied as rates, resulted in significant increases for many ratepayers after a general revaluation of properties. The Rates Action Group, a voluntary association representing ratepayer bodies, challenged the legality and constitutionality of levying sewerage and refuse removal charges based solely or partly on property value, contending that such charges were not authorised under the Local Government: Municipal Systems Act 32 of 2000 and were unlawful.
