 The Indiza group appealed the decision, claiming that the correct tender process had not been followed and that their bid had been unfairly excluded; however, their legal challenge was dismissed by the Pietermaritzburg High Court in February 2007.The final obstacle was a delay in the approval of the project's Environmental Impact Assessment (EIA) by the South African Department of Environmental Affairs and Tourism.The EIA was eventually approved in August 2007; conditions attached being the appointment of an environmental control officer, issues of access from the nearby N2 freeway, and fauna and flora issues; in particular, the impact of construction and airport operations on a nearby colony of barn swallows.
