liable to be quashed. In other words, to maintain any chargesheet against a quasi-judicial authority something more has to be alleged than a mere mistake of law, e.g., in the nature of some extraneous consideration influencing the quasi-judicial order. Since nothing of the sort is alleged herein the impugned chargesheet is rendered illegal. The charge- sheet, if sustained, will thus impinge upon the confidence and independent functioning of a quasi judicial authority. The entire system of administrative adjudication whereunder quasi judicial powers are conferred on administrative authorities, would fall into disrepute if officers performing such functions are inhibited in performing their functions without fear or favour because of the constant threat of disciplinary proceedings.”
