A bench of justices Badar Durrez Ahmed and Sanjeev Sachdeva also allowed Digital Radio Broadcasting Ltd, which runs Red FM and is associated with Kalanithi Maran-promoted Sun TV, to participate in the e-auction scheduled to begin tomorrow.
"We quash the decision communicated by letter dated July 15, 2015, denying security clearance.
"The petitioners (Digital Radio Broadcasting Ltd of Delhi and Mumbai) shall be entitled to participate in the e-auction subject to fulfillment of the other conditions," the bench said.
The ministry had also told the court that they need 12 hours to configure the software to be used for the auction process.
Digital Radio Broadcasting Ltd, which runs Red FM in Delhi and Mumbai, had not been permitted by the government to take part in the auction on the ground that it had been denied security clearance due to its association Sun TV.
The radio channels had argued in court that former Telecom Minister Dayanidhi Maran was in no way connected with Digital Radio, while his brother Kalanithi only has an indirect shareholding of 21.6 per cent in the company.
Prosecution of Marans cannot be a reason for denying Red FM security clearance, they had argued.
