Will Justice M.S. Liberhan, who heads the commission looking into the demolition of the Babri Masjid, submit his report on December 31? Or will he ask for another extension? According to sources in the commission, its work has not quite taken off because of a lack of cooperation from key witnesses as well as successive governments at the Centre and in UP. The judge is believed to be very upset and could bring to the government's notice the hurdles he faces, rather than ask for an extension when his term gets over at the end of this month.
