A finance ministry official said Vodafone had threatened arbitration against something that had not happened. He said the UK-based telecom company was presuming it might happen.
The official said the provision of the Bilateral Investment Promotion and Protection Agreement between India and the Netherlands, under which the notice was served, might not apply to the Vodafone tax case as the investment was routed through the Cayman Islands.
Officials asked why the company sought protection under the BIPA when it had maintained the deal happened outside India.
"The move is premature. The company has every right to take legal recourse, but can you serve a notice on the assumption that there would be a dispute?" asked an official.
The BIPA between India and the Netherlands came into force in December 1996.
When contacted, the company said Vodafone International Holdings BV was a company constituted under the laws of the Netherlands and, therefore, an investor as defined under article 1(d) of the treaty.
The ministry officials ruled out a softening of stance on the Finance Bill proposal to retrospectively amend section 9
