Curtains came down on the legal battle of 1993 Mumbai serial bomb blasts convict Yakub Memon as the Supreme Court dismissed his petition on Wednesday, seeking a stay of his execution slated for July 30 and quashing of death warrant.

The apex court had earlier dismissed the curative petition of Yakub. A three-judge bench comprising Justices Dipak Misra, Prafulla C. Pant and Amitava Roy said proper procedure was followed in disposing of Yakub's curative petition.

"Issuance of death warrant cannot be faulted with," said the apex court bench headed by Justice Dipak Misra, while rejecting Memon's plea. Pronouncing the order, Justice Misra said, 'we don't find any legal fallacy' with the issuance of death warrant by the TADA court on April 30.

The court order came after a day-long hearing on the petition by Memon and also a reference by two judge-bench on the appropriateness of another bench that had heard Memon's curative petition and rejected it on July 21, 2015.

This reference was made following a split verdict between Justice Anil R. Dave and Justice Kurien Joseph on Tuesday.

Dealing with the reference, the court said that the curative petition that "was decided by the three seniormost judges cannot be regarded as void or inappropriate" in context of the principle that was laid down by this court in an earlier judgement famously known as Hurra case.

"Thus, we disagree with the views expressed by Justice Joseph at this juncture," the court said, holding that "dismissal of curative petition by the three seniormost judges has to be regarded to be correct and not vitiated by any procedural irregularity".

Without saying anything on the second mercy petition moved by Memon before the Maharashtra governor after the rejection of his curative petition by the apex court on July 21, the court brought an end to the legal battle being waged by Memon challenging his death sentence.

Memon and 11 others were slapped with the death penalty by the special TADA court in July 2007 for the 1993 bomb blasts in which 257 people were killed and 712 were injured.

Meanwhile, Maharashtra Governor C.V. Rao on Wednesday rejected death row convict Yakub Memon's plea for clemency.

The development came shortly after a three-judge bench of the Supreme Court rejected Memon's appeal filed before it.

Special Public Prosecutor Ujjwal Nikam said that now there were no legal hurdles to implement the death warrant issued against Memon.
