NI Act

No doubt, the High Court has power for such direction, but I dont see any mandate for affidavit with the complaint, as filling complaint and giving evidence are two different things and even evidence on affidavit may or may not be accepted by the Court.

According to the  foundings of Hon'ble High Courts of different States almost all the complaint under various Act when filed in the respective Courts must accompanied with affidavit relating to the case is only to prove that the compainent is genuine and he is well acquainted with all facts and circumstances of the case.
