In 72 hours after he takes charge tomorrow as Chief Minister of Uttar Pradesh, Mulayam Singh Yadav will be called upon by the Supreme Court to spell out where his government stands on the Rae Bareli trial—in the Babri Masjid demolition case—against L K Advani, M M Joshi, Uma Bharti and others. For, the Supreme Court will begin hearing from September 1 a review petition challenging the Mayawati Government’s decision last year to refer the case to Rae Bareli which, in effect, let the leaders off the conspiracy charge.
