Departmental enquiry

It is felt that you should act on written orders only.

not agreed.

departmental inquiry is based on the reasonable evidence and criminal case is based on 100% evidence.

You can continue DE with attested document but not the criminal case.

You can handover the originals to the Police, by keeping xerox copies of the same.  However, the receipt must be perfectly acknowledged and you must take care to ensure that the covering letter is also countersigned by your Disc. Authority.  Before doing that you can inquire with police whether xerox copies will be sufficient for them.  It is not necessary for criminal court to have original documents with them, if they are privileged communication.  Sometimes if they are bulky then also originals are not submitted to police.  This is to say there can be exceptions to the rule that only originals should be submitted to police.

If the court wants your testimony as to the genuineness of the xerox documents you have submitted it can summon you as a witness.   There is no hard and fast rule to submit original documents to police.
