Vishal Yadav said he has already undergone the sentence of nine and half years without any remission. He said he never misused the bail granted to him earlier.
Vikas and Vishal killed Katara on the night of Feb 17, 2002 after abducting him from a marriage party in Uttar Pradesh's Ghaziabad.
The prosecution sought death penalty for the convicts saying Nitish Katara and Bharti Yadav - sister of Vikas Yadav and cousin of Vishal Yadav - were in an "intense relationship" and her family's opposition to their friendship led to the killing of Katara, son of an Indian Administrative Service officer.
Vikas and Bharti are children of former parliamentarian D.P. Yadav.
However, the Yadavs sought re-trial saying the trial was not conducted in accordance with law.
