The Bombay High Court struck down the Centre's one-time spectrum charge imposed in 2012 on Bharti Airtel and Vodafone Idea. The HC ruled that the government could not retrospectively alter the financial terms of telecom licences years after they had been granted. The Department of Telecommunications had sought ₹5,201 crore from Airtel and ₹1,069 crore from Vodafone Idea.
