The Ansal brothers, real estate barons who built and operated Delhi's Uphaar cinema, are guilty of causing death due to negligence and one of them must go to jail within four weeks, the Supreme Court ruled today. Gopal Ansal, 69, has been given a year-long sentence; he has been given a month to surrender and be moved to prison, judges said. Sushil Ansal will not be jailed because of his age, they said; he is 77. Jail time served earlier by the Ansals was factored into today's verdict.
