The Commission of Inquiry, enquiring into the circumstances that led to the killing of 30-year-old Thangjam Manorama in Manipur, would submit its report to the Manipur Government by November 12.
Soldiers of the Assam Rifles were alleged to have raped and killed Manorama Devi.
Retired Judge C Upendra, who heads the Commission, said it had completed examining witnesses of Assam Rifles, family members of Manorama and others.
The Commission had been set up by the Manipur government following widespread protests against killing and alleged rape of Manorama, who was arrested by 17th Assam Rifles personnel on July 10.
An army court of inquiry had also been set up by Assam Rifles to inquire into the circumstances that led to the killing of Manorama, sources said.
