Supreme Court management has locked the main gate of the SC building barring entry of SC Bar Association President, Aitzaz and Executive Committee member, Ali Ahmad Kurd. Lawyers' leaders protesting this uncalled for ban on their entry into the SC building exchanged hot words with the representatives of the management on this occasion. It may be recalled that SC Bar Association had invited the deposed chief justice, Iftikhar Muhammad Chaudhry visiting the Bar this afternoon. Earlier, Islamabad administration had sealed all the roads leading to the judges' colony and the lawyers' leaders as well as the media representatives were stopped entering the colony by setting up pickets at both the gates of the colony.
