In case of ex-parte proceedings, you should allow the CE to participate in the proceedings at any stage, he desires.
You may suspend the proceedings, if the CE dies or is dismissed or removed from service and refer the case to the DA.
You should permit production of new evidence only if there is inherent lacuna in the evidence already recorded.
In part-heard inquiries, you are free to take up proceedings, de novo, but this should be done in exceptional cases only. It is better to start from where they were left.

In case of ‘Court Witness’, you should allow cross examination by both parties – PO and CE.
Please ask mandatory questions at the close of proceedings where the CE does not opt to be his own witness.
You should allow copy of the written brief of the PO to the CE. CE may be allowed to file his written brief after going through the written brief of the PO.
You should submit your full report of the inquiry along with original records to the DA.
Please do not delegate functions of holding of inquiry to other person.
Please do not hold inquiry according to your own methods. Please follow prescribed procedure.
Please do not call for the documents or witnesses to decide the question of their relevancy.
Please do not requisition additional documents from the DA and/or the PO. You should write direct to the custodian of the documents.
Please do not insist that witnesses be produced in any particular sequence befor you in the inquiry. It should be left to the respective parties.
