Hindu petitioners demanding carbon dating to determine the age of a purported 'Shivling' found in Varanasi's Gyanvapi mosque complex have said they will approach the country's top court against the city's senior most judge's rejection of their appeal. "The court said that any kind of survey in the Wazookhana would be a violation of the order of the Supreme Court. We will go to the Supreme Court against the order of the Varanasi Court," Sudhir Tripathi, the lawyer representing the petitioners, told NDTV.
