New Delhi: One of the four Nirbhaya case convicts, Pawan Gupta, has filed a review plea against the Supreme Court's decision dismissing his juvenility claim at the time of the gruesome rape and murder case that shook the nation in 2012. Pawan Gupta and three others were earlier scheduled to be hanged on February 1.

On January 20, the Supreme Court had rejected Pawan Gupta's petition of juvenility and had held that the issue has been decided based on documents and cannot be re-exercised.

Yet, he has again filed a review plea just a day ahead of his scheduled hanging along with the three other convicts namely Akshay Thakur, Vinay Kumar Sharma and Mukesh Singh.

The death row convicts had on Thursday moved a trial court with a plea to adjourn the February 1 execution "sine die" saying they are yet to avail their remaining legal remedies. The Supreme Court dismissed the third curative petition on Thursday.

Convict Vinay Sharma had on Wednesday filed a mercy plea before the President and the apex court today rejected the curative petition of Akshay Kumar Singh, who is likely to file a mercy plea soon.

Of the four convicts, Mukesh Kumar Singh has exhausted all his legal remedies, including the mercy plea which was dismissed by President Ram Nath Kovind on January 17 and the appeal against the rejection was thrown out by Supreme Court on Wednesday.

The Supreme Court guidelines also stipulate that convicts cannot be hanged until 14 days after their mercy plea has been rejected by the President.
