In a subtle warning, Delhi High Court today told Vodafone that it would be taking a risk if it did not file a reply to the Income Tax department's show cause notice. The department, in the notice, had asked the company to show cause why its 2011-12 financial records not be subjected to special audit to arrive at the total income for assessment year 2012-13. A bench of justices S Muralidhar and Vibhu Bakhru made the observation after the IT department said the telecom major has not yet responded to the show cause notice and was trying to delay the assessment process beyond the March 31 deadline. The court adjourned the matter to Wednesday but made it clear that it would not grant the company any time on next date to file its response to the show cause notice of the IT department.
