The high court had come down heavily on the UP government,saying that out of the three years and three months which elapsed in deciding Koli's mercy petition, "as many as 26 months" were taken up by the Uttar Pradesh government itself, which was "unnecessary and unreasonable".
"Prolonged detention and the consequent wait for execution of death sentence is dehumanising for the person concerned and violates Article 21 of the Constitution," the court had said.
Koli had filed his mercy petition before the Governor on May 7, 2011, which was rejected only on April 2, 2013, and forwarded to the Union Home Ministry on July 19, 2013, after the elapse of nearly three months.
Both Koli and Pandher were named as accused in the serial killings and awarded death sentence in the Rimpa Haldar case.
However, on September 11, 2009 the Allahabad High Court acquitted Pandher and upheld the conviction of Koli while making it clear that the judgement shall have no bearing on trial in other related cases.
Koli moved the Supreme Court but his appeal against the trial court order was rejected following which he filed his mercy petition.
After the rejection of mercy petition, Koli had filed a recall application before the Supreme Court but it was also turned down.
On October 31, 2014, three days after the review petition of Koli was turned down by the apex court, the PUDR approached the high court with the PIl.
