The case focuses on the problems of getting environmental clearance for the Navi Mumbai International Airport (NMIA). While the concept of a second airport for Mumbai began as early as 1995, the planning began more actively in 2007, after the modernisation process of the existing airport was put in place. The NMIA was soon mired in controversy, based on the Environmental Impact Assessment. The Ministry of Environment and Forests (MoEF) appointed an Expert Appraisal Committee to take decisions regarding the NMIA and its proposed location. The City and Industrial Development Corporation, the Government of Maharashtra, the Ministry of Civil Aviation and the MoEF had their points of view. There was a process of negotiation, review and modification of plans. Finally, in November 2010, the approval with conditions was granted. The case provides an opportunity to crystallise lessons in such a process for any major infrastructural project.
