India's Supreme Court has set 25th October as the next hearing for Vodafone's tax appeal. Vodafone could owe the Indian government more than 120 billion rupees (around £1.7 billion) following a court ruling earlier this month, although the company insists nothing is due. The case centres on Vodafone's 2007 purchase of Hutchison's Indian business, which saw Netherlands-based Vodafone International acquiring a stake in Hong Kong-based Hutchison; the stake was owned by a company in the Cayman Islands. Mumbai's High Court says Capital Gains Tax is payable and should have been collected by Vodafone.
