In August 2005, Singh filed a special leave petition with the apex court, seeking acquittal. He asserted that his case was based on hearsay and circumstantial evidence, claiming that he had not led the killings. The Supreme Court of India admitted his appeal in October 2005. In February 2007, Singh petitioned the Supreme Court to release him on bail, stating that he was the primary livelihood earner in his family, including his dependent 75-year-old mother. In October 2007, his petition was denied by the Supreme Court.
