Jethmalani told the court that preparations were being made to hang Bhullar like Mumbai attack terrorist Ajmal Kasab and parliament attack convict Afzal Guru.
Navneet Kaur contended that the apex court order of April 12 rejecting Bhullar's plea to commute his death sentence into life imprisonment on the grounds of inordinate delay in deciding his mercy petitions by the president was based on "non-application of mind, non-consideration of relevant circumstances and presumably made on extraneous grounds and/or irrelevant facts".
Dismissing his plea, challenging the rejection of his mercy plea by the president, the Supreme Court April 12 had refused to commute his death sentence to life imprisonment.
Bhullar had filed a mercy petition on Jan 14, 2003, which was rejected by the president May 25, 2011.
Bhullar was given capital punishment for the 1993 blast at the Youth Congress office, a stone's throw from Parliament House in Delhi, which left nine dead. The attack was targeted against then Youth Congress leader MS Bitta.
