Yakub Memon, a convict in the 1993 Mumbai serial blasts case, on Thursday moved the Supreme Court challenging the death warrant for his execution on 30 July.

Memon sought a stay of the execution and quashing of the death warrant on the grounds that due procedure was not followed for issuing it.

The apex court had on Tuesday rejected Memon's curative petition saying it was void of merit. The same day, Memon filed a fresh mercy petition before the Maharashtra governor seeking to commute his death sentence into life imprisonment.

In his latest petition to the Supreme Court, Memon said that the death warrant was issued before he could exhaust all his legal remedies. It was issued and the day of execution for 30 July was fixed even as his curative petition was still pending before the apex court.

Earlier this year, the SC had quashed death warrant issued for two death row convicts in a multiple murder case on the grounds that it was illegal as procedure was not followed.
