Telkom SA SOC Limited, a state-owned communications provider licensed under the Electronic Communications Act 36 of 2005, developed a nationwide fibre-optic network infrastructure. In 2015, Telkom decided to improve infrastructure in Cape Town by constructing 135 cellular phone masts. It leased property from the estate of Mr Birch Kalu in Heathfield for erecting a mast. The property was zoned single residential zone 1 under City of Cape Town bylaws, which did not permit cellular masts. Telkom applied for rezoning in January 2016 but proceeded to build the mast two weeks later before receiving approval. Local residents objected, and the City imposed an administrative penalty and suspended Telkom's rezoning application pending payment. Telkom challenged the validity of the City's bylaw and policy, arguing the City lacked competence to regulate telecommunications and that the bylaw conflicted with section 22 of the Electronic Communications Act.
