Ahead of the executions of convicts in the 2012 Nirbhaya gangrape case, convict Pawan Kumar Gupta filed a curative plea in the Supreme Court on Friday. Nirbhaya convict Pawan Gupta filed a curative petition in the Supreme Court of India on Friday. He is among the four convicts to be executed on March 3 of this year. In his plea to the country's highest court, Pawan sought his death sentence to be commuted to a life imprisonment sentence. Earlier this month, the Patiala House court in Delhi signed fresh death warrants for the four men convicted in the 2012 gangrape case that shook the country. A 'black warrant' signed in their names was revoked by an additional sessions judge in Delhi earlier this year after one of the convicts filed a mercy plea before President Ram Nath Kovind that was turned down.

In its plea, the central government has challenged the Delhi High Court verdict which held that all of the four convicts in the case must be executed together. Similar appeals have been made by family members of the 23-year-old medical student who died as a result of fatal internal wounds incurred on the night of December 8, 2012. Pawan Gupta is the fourth convict to file the curative petition in the SC. In January of this year, the same plea filed by convict Akshay Thakur was rejected by a bench of India's highest court. Similar pleas filed by convicts Mukesh Singh and Vinay Sharma were also heard and dismissed by a five-judge bench of the Supreme Court.
