Should he be hanged? Is India doing justice?

Story:
Professor Devender Pal Singh Bhullar, who is currently confined in Tihar Jail, Delhi (Ind.) and is awaiting execution of death sentence pronounced by the Indian courts and confirmed by Supreme Court of India in Devender Pal Singh Versus State National Capital of Delhi and others. case in a "split decision". Once to be a lecturer at Guru Nanak Engineering College (GNE) Ludhiana, Bhullar had to leave his house when Sumedh Saini, then SSP of Punjab Police abducted and killed his father, uncle and engineer friend in 1991.

Bhullar left India and was passing through Germany when he was stopped by German authorities at Frankfurt airport and was found travelling without proper papers. He was deported to India and here he was tired for his alleged involvement in a Bomb Blast leaving 9 persons dead. Police said that the target of this 1993 blast was then congress's youth leader Maninder Jeet Singh Bitta, who was injured during this blast.

It is important to note that all 133 witnesses called by prosecution failed to support police story and to confirm any involvement of Prof. Devinder Pal Singh Bhullar in 1993 Delhi blast.

Bhullar is convicted and sentenced to death solely on the bases of extra-judicial confession. This confession was taken while Bhullar was in Police custody. In the court during trial Bhullar accused the police for compelling him to sign blank papers while he was in their custody and denied that he had ever made any such confession.

Justice M. B. Shah, who was heading three judges constitutional bench at the SC labeled the confession as "teller made confession" and rejected it.

Justice MB Shah acquitted Bhullar while two other judges confirmed the death sentence.
•In his absence the German courts (Verwaltungsgericht Frankfurt, Case 8E50399\94.A(1)) ruled that he should not have been returned as his life would be in danger in India - overruling the prior decision.
•By deporting someone to a death-penalty prone country Germany violated the European Convention on Human Rights and remains morally obliged to do all it can to seek the Professor's immediate release.
•Professor Bhullar continues to suffer and may soon lose his fight for life due to the brutal and unjust regime in India. On 26 May 2011 after more than 7 years the Indian President rejected his plea for clemency and gave the go ahead for him to be hanged.
•While in India Professor Bhullar was put on trial in a conspiracy case and on 17 December 2002 his sentence to death was confirmed by the Supreme Court although based on erroneous information, it is important to note the following facts:
•Amnesty International reported that Professor Bhullar's case was highly contentious, it was the first in India's Supreme Court's history, someone was sentenced to death on the basis of a split judgment
•For the first time in India's Supreme Court's history, someone was sentenced to death on the basis of a split judgment. The presiding judge, Justice Shah acquitted the accused whereas the other two judges, Justice Aggarwal and Justice Passayat upheld the death sentence.
•Justice Shah acquitted Professor Bhullar stating that the conspiracy theory falls flat as the "rest of the accused who are named in the confessional statement are not convicted or tried."
•The confession statement, allegedly extracted under torture, was signed by a thumbprint. For a man who is highly educated, the sign of a thumbprint implies duress. A confession made before a police officer under normal criminal law is not admissible as evidence.
•Furthermore, none of the 133 witnesses produced by the prosecution, while the case was in the lower court, identified Professor Bhullar
