While upholding the life term awarded to seven out of the 18 policemen accused of killing a 22-year-old MBA student in a fake encounter in Dehradun in 2009, a bench of justices S Muralidhar and I S Mehta said that despite transferring the trial to Delhi, a large number of witnesses turned hostile.
The court has acquitted other accused.
The court said that this pointed to the "nonexistent protection given to witnesses and victims".
"Despite their statements being recorded under the criminal procedure code, the prosecution could do little to stop these witnesses from turning hostile in court.
"But for PW15 (one of the witnesses), a local resident, standing firm, the entire trial may have collapsed. This is yet another case that underscores the urgent need for a robust scheme of protection to witnesses and victims," the bench said.
