"This is unprecendented. As far as I know, such a thing has never happened before," says a senior lawyer. "Obviously there's some deal with the Russians. But one can't compromise on internal security except in exceptional circumstances. For instance, if Russia had threatened us with a nuclear attack, perhaps such a pardon may then have been considered," is the wry response of Prashant Bhushan, a public interest Supreme Court lawyer. "But this is a matter involving our national laws and unless we've been blackmailed, the pardon shouldn't have been given," he says. Earlier, in response to appeals from the Duma (parliament), the Russian Orthodox Church and the pilot's families, Delhi had maintained that the issue was before the courts and that the law would have to take its course.
