For registration of FIR and investigation purpose, no prior sanction require but only to initiate prosecution by court.

This is central provision and will prevail over local/state when anomaly exits.

Well, sanction ombudsman act is different and dose not apply for PVC cases.

sanction is mandatory only for prosecution and not for initiating investigation/inquiry.

Yes section 17 of PC act applies on this situation as ombudsman is competent authority to order investigation against govt servant.

1. As per the information mentioned in the present query, makes it clear that the provisions of two different acts are supplementary to each other.
2. Yes, it can be ordered for investigation, but as per the section itself it might require prior inquiry also.
3. Rest, would try to do more research on it and come out with some case laws.
