Dear Imran,
It is not the fault of the departmental authorities, as when the CBI feels that their case is likely to fail in the court of law, they usual play the trick to refer the case to the departmental inquiry. Rather, they send the pre-drafted chargesheet to the disciplinary authority for taking necessary disciplinary action against the official. The departmental authorities normally do not decline, rather have no guts to decline the instructions of the CBI and hence they issue the charge sheet to the concerned official without rethinking on that.
However, defence assistant of the charged official need be so strong to defend the case to prove that it is the mischief of the CBI to intentionally book the official when they have already failed in the court of law. Departmental authorities have no superiority over any court of law. If defended properly during the inquiry proceedings, the inquiry officer and the disciplinary authority are bound to agree that when the charged official has already been acquited by honourable court of law, they do not enjoy any overriding power over the the court of law against its judgment.
