Telkom SA SOC Ltd planned to roll out telecommunications infrastructure, including freestanding base telecommunication stations (cell phone masts), in Cape Town. One such mast was erected on a property in Heathfield owned by the Estate Late Birch Kalu. The property was zoned Single Residential Zone 1 under the City of Cape Town’s Municipal Planning By-Law, which did not permit such infrastructure. Telkom applied for rezoning but erected the mast before approval was granted. The City objected, asserting that Telkom acted unlawfully by breaching zoning provisions and building regulations. Telkom challenged the constitutionality of the by-law and the City’s Telecommunications Mast Infrastructure Policy, arguing that section 22 of the Electronic Communications Act 36 of 2005 entitled it to enter land and erect infrastructure without municipal consent.
