Tata's senior counsel Harish Salve also pleaded for a direction from the Court to ensure that conversations tapped by government agencies in the 'Radia tapes' affair are not leaked and misused.
He said the government has been "lackadaisical" in finding out how the tapped telephonic conversations of former corporate lobbyist Niira Radia with top politicians, bureaucrats and businessmen including him were leaked.
Later, Tata Sons, in a statement, said, "Ratan Tata has filed this writ petition on a matter of principle. He believes privacy is an important right for every individual and is keenly following the progress of this case."
Salve, appearing before the bench also comprising Justice K S Radhakrishnan, said there is need for an independent panel as the committee which reviews intercepted calls is headed by the Cabinet Secretary who is too busy to look into numerous cases of phone tapping in the country.
