A bench of Justices G S Singhvi and S J Mukhopadhaya had heard elaborate arguments on three petitions - one by Bhullar, second by his wife Navneet Kaur and third by NGO ''Justice on Trial Trust''.
The bench had reserved its verdict on April 19 last year. Bhullar was sentenced to death in 2001 for plotting terror attacks on Punjab SSP Sumedh Singh Saini and the then Youth Congress President M.S. Bitta in 1993, leading to several deaths in New Delhi.
The apex court had on 26 March, 2002, dismissed Bhullar's appeal against the death sentence awarded by trial court and endorsed by the Delhi High Court.
He had filed a review petition, which was also dismissed on 17 December, 2002. Bhullar had then moved a curative petition, which too had been rejected, by the apex court on March 12, 2003.
