In Indian defence purchases, the size of the contract decides who approves it. In 2016 the Institute for Defence Studies and Analyses described the levels. The Defence Secretary could approve up to 300 crore rupees and the Defence Minister up to 500 crore. “All cases with negotiated cost of INR 500 to 1,000 crore require the approval of the Finance Minister.” Larger cases went to the Cabinet Committee on Security. The figures may have changed since.
