When the idea to develop the site was mooted in 2001, Cosmo City was met with resistance from wealthy property owners, mostly members of the Jukskei Crocodile Catchment Area Forum. They argued that the development would affect the value of their properties.
The property owners applied to the Johannesburg high court, opposing the development. Their application was withdrawn after they failed to send legal representatives to the court hearing and failed to meet a deadline to provide security to cover legal costs.
The Provincial Township Board dismissed an appeal by the property owners on October 6 2004.
