Iftikhar Ahmed, a relative of the convict Shahzad Ahmed, said they would go through the court's judgement and find out the basis on which he had been convicted.
"It is a very sad judgement. We are unable to understand the ground on which he had been convicted. We thought that the judgement would be in our favour and he would be acquitted," said Ahmed, grandfather of the convict, in Azamgarh.
A Delhi court convicted Ahmed in the 2008 Batla House encounter incident in which a Delhi Police Special Cell police Inspector Mohan Chand Sharma was killed.
The court fixed July 29 for pronouncement of sentence for offences that entails death penalty for murder of Sharma.
