A) ABSTRACT / HEADNOTE

The dispute concerned the claim for additional profit bonus for the year 1955–56 under the Full Bench Formula evolved in The Mill Owners’ Association, Bombay v. Rashtriya Mill Mazdoor Sangh, Bombay (1950 L.L.J. 1247). The workmen sought four months’ basic wages as bonus, while the company had already paid 2½ months’ bonus. The main points in contention included (i) exclusion of certain alleged extraneous income from gross profits; (ii) treatment of Rs. 3 lakhs profit arising from change in stock valuation method; and (iii) entitlement to 4% return on depreciation reserves used as working capital. The Supreme Court held that profits earned in the normal course of business, such as rent, estate revenue, sale of barrels, and scrap, are not “extraneous income” merely because no direct proof of labour’s contribution exists. However, income from fortuitous or non-recurring events like accounting changes, or from prior years, may be excluded. The Court allowed return on depreciation reserves actually used as working capital. Upon recalculating, it found that the bonus already paid exceeded half of the available surplus, and thus no additional bonus was warranted. The award of the Industrial Tribunal granting more bonus was set aside.

C) INTRODUCTION AND BACKGROUND OF JUDGEMENT

The case arose from an industrial dispute between the Tata Oil Mills Co. Ltd., Bombay and its workmen regarding profit bonus for the financial year 1955–56. The demand, referred by the Government of Bombay, sought unconditional bonus equal to four months’ basic wages for all employees earning below Rs. 500 per month. The company had already paid 2½ months’ wages as bonus. The core disagreement revolved around the calculation of gross profits and available surplus under the Full Bench Formula. The company argued that certain income items were extraneous to labour’s effort, that Rs. 3 lakhs profit from a change in stock valuation was unreal in terms of labour contribution, and that it was entitled to 4% interest on depreciation reserves used as working capital. The Industrial Tribunal rejected these claims, granting an additional 1½ months’ bonus. On appeal, the Supreme Court clarified the scope of “extraneous income” and the permissible deductions under the formula, significantly affecting future bonus adjudication.

D) FACTS OF THE CASE

• The company was established in 1917, and shareholders began receiving dividends only from 1940.

• For 1955–56, it declared a 12% dividend (tax-free) and had already paid 2½ months’ bonus.

• Workmen argued wages were below the living standard, and profits justified a four-month bonus.

• The company contended that available surplus under the Full Bench Formula did not support higher payment and that certain incomes should be excluded:

  1. Rent, light, and power receipts

  2. Estate revenue from sale of excess coconuts

  3. Profit on sale of empty barrels

  4. Sale of tin cans, scrap, logs, planks, gunnies

  5. Excess provision for prior year expenses

  6. Tax refunds from earlier assessments

• Additionally, Rs. 3 lakhs profit arose from change in stock valuation method.

• The company sought return on depreciation reserve used as working capital.

• The Tribunal excluded only the two admitted extraneous items (prior provision reversal and tax refund) but included the other four disputed items and the Rs. 3 lakhs in gross profits, while disallowing return on depreciation reserve.

• Supreme Court granted special leave to appeal.

E) LEGAL ISSUES RAISED

i. Whether receipts like rent, estate revenue, sale of barrels, and scrap constitute “extraneous income” under the Full Bench Formula.
ii. Whether Rs. 3 lakhs profit from change in stock valuation is to be excluded as non-recurring/fortuitous income unrelated to labour.
iii. Whether the company is entitled to 4% return on depreciation reserve used as working capital.
iv. Whether available surplus justified bonus beyond what had been paid.

F) PETITIONER/ APPELLANT’S ARGUMENTS

i. The counsel for Tata Oil Mills submitted that the four disputed income heads were unrelated to labour’s effort and thus excluded in several Tribunal precedents based on Mill Owners’ Association and Shalimar Rope Works rulings.

ii. The Rs. 3 lakhs profit from stock valuation change was purely an accounting gain, not real operational income, falling in the category of “fortuitous” gains.

iii. Return on depreciation reserve used as working capital was justified since, if not so used, the company would borrow at interest.

iv. Cited Muir Mills Co. Ltd. v. Suti Mills Mazdoor Union to stress that profit bonus requires a connection between labour’s contribution and profits.

G) RESPONDENT’S ARGUMENTS

i. The workmen’s counsel contended that the disputed items arose in the normal course of business and indirectly involved labour contribution, hence includable in gross profits.
ii. Claimed that depreciation reserve represented a capital replacement fund and should not yield return as working capital for bonus computation.
iii. Opposed exclusion of the Rs. 3 lakhs profit, arguing it was part of current year’s accounts.
iv. Asserted that the company’s high dividend and overall surplus justified further bonus payment.

H) JUDGEMENT

a. Ratio Decidendi

• Normal course of business income is generally a joint product of capital and labour; direct proof of labour’s contribution to each item is not required.

• Extraneous income is limited to:

  1. Profits not actually arising in the bonus year (e.g., prior year reversals, tax refunds)

  2. Gains from fortuitous events unconnected to labour (e.g., accounting changes)

  3. Proceeds from sale of fixed/capital assets

• Rs. 3 lakhs profit from stock valuation change falls under “fortuitous” and is excluded.

• 4% return is allowed on depreciation reserves actually used as working capital.

b. Obiter Dicta

• The principle of joint contribution of capital and labour must be applied pragmatically, without fragmenting business receipts into labour-contributed and non-labour-contributed categories unless clearly extraneous.

• In future, workmen may contest actual usage of reserves through cross-examination and evidence.

c. Guidelines 

1. Identify profits earned in the year; exclude prior period adjustments and purely fortuitous gains.

2. Include receipts from regular operations even if indirect labour contribution is shown.

3. Allow fair return on reserves genuinely deployed as working capital.

4. Avoid overcompensating labour where surplus is already adequately shared among stakeholders.

I) CONCLUSION & COMMENTS

This judgment refined the definition of “extraneous income” in bonus calculations, rejecting overly narrow interpretations by lower tribunals. It affirmed that all operational receipts are part of gross profits unless they are prior-period, fortuitous, or from capital asset sales. The decision also established that reserves, including depreciation reserves, attract return if deployed as working capital, influencing industrial adjudication on bonus claims. By recalculating the available surplus and finding that labour had already received more than half, the Court reinforced a balanced distribution between industry, shareholders, and workers, aligning with the equitable principles of the Full Bench Formula.
