Summarize the following court judgment. Appeal No. 93 of 1959. Appeal by special leave from the Award dated May 13	 1957	 of the Industrial Tribunal	 Bombay	 in Reference (I.T.) No. 166 of 1955. R. J. Kolah	 section N. Andley	 J. B. Dadachanji	 Rameshwar Nath and P. L. Vohra	 for the appellants. K. B. Chaudhury and Janardan Sharma	 for the respondents Nos. 1 and 2. 379 1960. March 24. The Judgment of the Court was delivered by WANCHOO	 J. This appeal by special leave raises two questions	 namely	 (i) bonus for the year 1952 and (ii) retrospective operation of the order of the Industrial Tribunal relating to increase in wages. The appellant is a company manufacturing barrels and drums at Bombay. There was a dispute between the appellant and its workmen about a number of matters	 which was referred to the tribunal by the Government of Bombay on November 17	 1955. In respect of the two matters which are now raised in appeal the workmen claimed (i) four months wages including dearness allowance as bonus for the year 1952 and (ii) retrospective operation of the wage scale to be fixed by the tribunal from March 1	 1952. So far as the increase in wages	 is concerned	 the appellant agreed to the scale suggested by the tribunal but it opposed the grant of the increased scale retrospectively and also wanted that the increased wages should be linked to some guaranteed production. The reason for this was that the appellant felt that there had been deliberate slowing down of production by the workmen in the previous years. The tribunal was of opinion that there was some justification in the appellant 's contention that there had been considerable go slow which had affected production. Taking that into account it ordered that retrospective effect should be given to its order which was passed on May 13	 1957 from June 1	 1956. As to the linking of the increased wages to a certain guaranteed production it found it difficult to lay down any norm itself; but it made it clear that the increase in wages was made by it on the basis that the workers would give a certain reasonable production and noted that the workers were agreeable to do that. It	 however	 recommended that immediately after the. award had been given	 an expert should be appointed by agreement	 if possible	 to go into this question. It also said that in case it was not possible to appoint an expert by agreement it would be open to the appellant to appoint one. 380 The appellant 's contention before us is that the tribunal having found some justification in its contention that there had been considerable go slow should not have given retrospective effect at all to the order relating to the increase in wages. This matter has been considered fully by the tribunal and it came to the conclusion that increase in wages should be granted from June 1	 1956. This could hardly be called retrospective considering that the reference was made in November 1955 ; in any case the tribunal rejected the claim of the workmen for retrospective operation for the period of over four years from March 1952 to May 1956 and a good deal of go slow was practised during this period. In the circumstances we see no reason for interference with the order of the tribunal fixing the date as June 1	 1956	 from which the increased wages should come into force. This brings us to the next question relating to bonus. The tribunal has awarded five months ' basic wages by way of bonus. The first contention in this connection is that the workmen had only claimed four months ' basic wages and the tribunal could not have awarded anything more than what the workmen claimed. This in our opinion is incorrect. The workmen had claimed four months ' wages including dearness allowance as bonus. Five months ' basic wages which the tribunal has allowed are admittedly less than the claim put forward (namely	 four months ' wages including dearness allowance). In the circumstances the tribunal certainly had jurisdiction to award what it has awarded to the workmen. The next question is whether the tribunal was justified in awarding as much as five months ' basic wages on the basis of the Full Bench formula	 which is generally applied to these matters. The gross profit found by the tribunal is not challenged	 namely	 Rs. 5.05 lacs. The tribunal has then allowed Rs. 1.36 lacs as depreciation	 leaving a balance of Rs. 3.69	 lacs. Deducting income tax from this at seven annas in a rupee (i.e. Rs. 1.61 lacs)	 we are left with a balance of Rs. 2.08 lacs. Six per cent. per annum interest on the paid up capital along with four per cent. interest on the working capital comes to Rs. 16	000	 leaving an available 381 surplus of Rs. 1.92 lacs. Out of this	 the tribunal has allowed five months ' basic wages as bonus which according to its calculations comes to Rs. 91	000	 leaving Rs. 1.01 lacs. There will be a rebate of Rs. 40	000 on this sum	 leaving a total of Rs. 1.41 lacs with the appellant. On these figures	 the bonus awarded by the tribunal cannot be interfered with. The appellant	 however	 draws our attention to two circumstances in this connection. In the first place it urges that the tribunal has not taken into account anything for rehabilitation. But it may be mentioned that the appellant had proved no rehabilitation amount as such. What it had done was to appropriate Rs. 3.16 lacs towards depreciation	 which of course was not the proper amount of notional normal depreciation	 which is allowable under the formula. Our attention is drawn	 however	 to the figures filed by the workmen in exhibit U 4 in which Rs. 40	000 has been allowed towards rehabilitation. Even accepting this concession by the workmen and deducting it from the figures given by us above	 the appellant would still be left with Rs. 1.01 lacs after paying five months ' basic wages as bonus. There is thus no reason to interfere with the award of bonus on this ground. Lastly it is urged that according to the income tax assessment which was actually made in this case sometime after the order of the tribunal	 the appellant has been assessed to income tax amounting to Rs. 2.35 lacs. The appellant claims that it should be allowed this entire amount and not the notional figure calculated by us	 namely	 Rs. 1.61 lacs as income tax. We are of opinion that for the purpose of the Full Bench formula	 the income tax payable has to be deducted on the figures worked out according to the formula and it is immaterial what the actual income tax paid is whether more or less. In this particular case	 the income tax appears to be more because certain items which were challenged by the workmen but were allowed as proper expense by the tribunal have apparently not been allowed as proper expense by the income tax department. The industrial tribunal	 however	 is not concerned directly with what the income 49 382 tax authorities assess as actual income tax in a particular year; it is concerned with working out the Full Bench formula in accordance with its notional calculations and this is what has been done in this case. There is no ground therefore for interference with the award of bonus for this reason either. We therefore dismiss the appeal	 but in the circumstances pass no order as to costs. Appeal dismissed.

The workmen of the appellant company claimed four months	 wages including dearness allowance as bonus for the year 1952	 and retrospective operation of the increased wage scale to be fixed by the Industrial Tribunal from March 1	 1952. The appellant agreed to the increased wage scale suggested by the Tribunal but wanted that it should be linked to some guaranteed production	 and opposed its operation retrospectively on the ground that there had been eliberate slowing down of production by the workmen in the previous years. The Tribunal found that there was some justification in the appellant 's contention that there was considerable go slow which had affected production and ordered that retrospective effect should be given to its order relating to increase in wages which was passed on May 13	 1957	 from June 1	 1956	 and not March 1	 1952	 as claimed by the workmen	 The increased wages were not linked to any guaranteed production but it was made clear that the workers would give certain reasonable production to which the workmen agreed. The Tribunal granted five months basic wages by way of bonus on the basis of the Full Bench formula which is generally applied to these matters. On appeal by the Appellant company by special leave : Held	 that there was no reason for interference with the order of the Tribunal fixing the date as June 1	 1956	 from which the increased wages should come into force and that the Tribunal had jurisdiction to award five months ' basic wages by way of bonus. For the purpose of the Full Bench formula	 the incometax payable has to be deducted on the figures worked out according to the formula and it is immaterial what the actual income tax paid is whether more or less.
