The principles of natural justice have undergone a sea change. The earlier view that even a small violation would result in the order being rendered a nullity is not correct. Some real prejudice must be caused to the complainant by the refusal to follow natural justice. The prejudice must not merely be the apprehension of a litigant. No prejudice is caused to the person complaining of the breach of natural justice where such person does not dispute the case against him or it. There is a clear distinction between cases where there was no hearing at all and the cases where there was mere technical infringement of the principle   ( CA No 3498 of 2020 , Arising ALP (C ) No. 5136 of 2020  dt .16 -10 -2020 )
