"The said Industrial Tribunal had the evidence before them that since the dismissal of the Appellant from the Royal Mail for the reason of `wilful delay of mail' that a number of other postmen had committed the same offence but were not dismissed. Therefore I believe that the decision of the said Industrial Tribunal was perverse. I believe that a reasonable Tribunal in reaching its decision will have taken into consideration that in a comparative situation Mr Singh has been accorded a grossly less favourable treatment than white postmen for the same offence from the same office.
