The Tribunal observed that it was not possible to say "that the increase in the turnover in the year under appeal was due to the extra efforts put in by these two employees or that the employees had worked in the hope of receiving extra commission" and since bonus equivalent to three months ' salary was paid to saheb Dayal and Gurditta Mal in addition to their salary during the relevant accounting year, any extra services rendered by them, if any, "should be deemed to have been covered by the payment of this bonus" Since in the view taken by the Tribunal it was necessary that there should be some extra services rendered by Saheb Dayal and Gurditta Mal for which payment of commission could be said to be justi fied and there was nothing to show that any such extra services were rendered by them, the Tribunal came to the conclusion that the payment of commission could not be said to be justified on grounds of commercial expediency and section 36, sub section (1), clause (ii) had no application.
