They are: (a) Was the Industrial Tribunal competent to entertain the dispute at all ? (b) Was the claim for bonus for the years 1966 69 barred by res judicata ? (c) Was there, apart from profit based bonus, customary bonus or bonus as a condition of service ? (d) If answer to (c) is in favour of the workmen, does the Bonus Act interdict such a demand since it does not provide for those categories of bonus and confines itself to profit based bonus, or does the Bonus Act speak on the topic of bonus of all species and, therefore, stands four square between a claim for bonus and its grant, unless it finds statutory expression in the provisions of that Act ? The first contention which, curiously enough, has appealed to the Industrial Tribunal, need not be investigated as it is devoid of merit and has rightly been given up by counsel for the respondent.
