Since its inception, the NBA linked its opposition to the Sardar Sarovar Project with larger issues concerning the nature of ongoing developmental projects, the efficacy of the model of development that the country followed and what constituted a public interest in a democracy. It demanded that there should be a cost-benefit analysis of the major developmental projects completed in the country so far.
