No reason was given by the tribunal for the delay in the award. Cairn said it is seeking full restitution for losses totalling more than USD 1.4 billion resulting from government expropriation of its investments in India in 2014. The company, which gave the country its biggest oil discovery, received a notice from the income tax department in January 2014, requesting information related to the group reorganisation done in 2006. Alongside, the department attached the company's near 10 per cent shareholding in its erstwhile subsidiary, Cairn India.
