Kumar's counsel S V Raju told Additional Chief Judicial Magistrate H S Khutwad that under Section 197 of the Criminal Procedure Code, the Centre's sanction has to be sought to prosecute Central government officials, which has not been granted in this case.
Raju also said that without previous sanctions, no court could take cognisance of offences alleged to have been committed by public servants while discharging their official duties.
However, the court said that the chargesheet is in a sealed cover and is yet to be verified by it.
Last week, the Central Bureau of Investigation (CBI) in a supplementary chargesheet charged Rajinder Kumar with murder and criminal conspiracy in the 2004 encounter case, while accusing three other serving officers of criminal conspiracy as well as other offences. But it left out Amit Shah, a close aide of Gujarat Chief Minister Narendra Modi, who was under the scanner in the case.
The court said that it would look into Kumar's contention.
