The respondents were owners of vacant stands in Lombardy Estate situated in the former Kungwini Local Municipality, which was absorbed into the City of Tshwane Metropolitan Municipality (the City) with effect from 1 July 2011. Under Kungwini administration, the respondents' properties were categorised as 'residential' for rates purposes. About a year after absorption, from July 2012, the respondents received invoices from the City showing massive retrospective increases in rates (up to 700% increases), backdated to July 2011. This resulted from the City re-categorising the properties from 'residential' to 'vacant' in a 2012 supplementary valuation roll published on 4 July 2012 and taking effect from 1 September 2012, applying the vacant land rate which was approximately 4.5 times higher than the residential rate. The City failed to comply with section 49 of the Municipal Property Rates Act 6 of 2004 (MPRA), which requires mandatory notice procedures including publication in the Provincial Gazette, media advertisements, and individual service on every property owner of notice of the valuation roll and opportunity to object. None of the respondents received individual notice as required by section 49(1)(c) of the MPRA. After unsuccessful attempts to obtain reasons from the City, the respondents launched a review application in June 2013 seeking to set aside the City's decisions.
