A bench of justices Sanjiv Khanna and Ashutosh Kumar directed Delhi Police to file their reply before February 25 on Rana's plea challenging trial court's August 8, 2014 verdict convicting 35-year-old Rana but acquitting 10 other co-accused in the case.
Rana in his appeal sought setting aside of the sessions court decision, saying it had failed to consider the mitigating circumstances.
Terming the trial court judgement was "bad in law", he had claimed that the judge had not considered the material evidence in his favour.
In a related development today, Rana and Shekhar Singh failed to file their responses on a plea of Delhi police challenging their acquittal from the charge of criminal conspiracy.
