Probably, there are three India legal remedies and one International Court remedy, still available to convicted Bhullar who is on death row.
1) Review petition against judgement delivered in April, 13.
This is his statutory right. He cannot be/ should not be hanged till statutory period of 30 days is over (That is till May,13)
2) In meantime, if he files review petition, he cannot be hanged till review is decided by same judges.
3) If review is rejected, then he can file a curative petition before 5 Judges against order rejecting review petition.
4) In the meantime, this case involves International Law issue of Rights of an Individual Versus Union of India.
Can an individual, whose deportation from Germany is held illegal, be hanged by India?
This point has to go to International Court of Justice or to some other International Forum.
Till these legal remedies are exhausted, in my view Bhullar should be hanged.
This is my personal view. I may be wrong also. 😦
