"Should a further demand for taxation be received by VIHBV or any member of the Group as a result of the retrospective legislation, we believe it is probable that we will be able to make a successful claim under the Dutch BIT and/or UK BIT," Vodafone said.
It added that the company did not carry a provision for this litigation or in respect of the retrospective legislation as on March 31, 2016, or previous reporting dates.
But the income tax department, taking refuge under the retrospective amendment in 2012, contends that tax is due and has sent notices to the company.
"On February 4, 2016, Vodafone International Holdings BV (VIHBV) received a reminder of an outstanding tax demand of Rs 221 billion. The latest reminder threatens enforcement action if the demand is not satisfied," Vodafone said in a statement.
The statement said VIHBV served its notice of arbitration under the Dutch BIT on April 17, 2014, formally commencing the Dutch arbitration proceedings.
The president of the International Court of Justice will now appoint the third arbitrator.
On June 15, 2015, Vodafone Group and Vodafone Consolidated Holdings served a trigger notice on the Indian government under the UK BIT in respect of retrospective tax claims under the Finance Act, 2012.
The Vodafone case relates to the retrospective amendment of I-T laws carried out by the UPA government in 2012 to overturn the Supreme Court verdict that had favoured Vodafone.
