With Vodafone’s victory in international arbitration in the Netherlands, the long and sorry saga of “retrospective taxation” should ideally be brought to a close. In 2007, the Indian income tax authorities had served a notice for Rs 7,990 crore in capital gains tax on Vodafone for its purchase of Hutchison India’s assets — which were routed through a tax haven, the Cayman Islands. The Anglo-Dutch telecom major fought the demand all the way to the Supreme Court, where it received a favourable judgment. In a move that shocked investors, however, the next Union Budget effectively closed the loophole that Vodafone had used in its deal — with retrospective effect. By 2016, the tax demand and interest had more than doubled to over Rs 22,000 crore. In that time, Vodafone had already appealed to international arbitration, saying that investments in India were governed by the Indo-Dutch bilateral investment treaty (as well as the India-UK bilateral investment treaty). It is this case that the telecom major has won, with the arbitrators saying the government’s behaviour violated the “fair and equitable treatment” clause in the bilateral investment treaty.
