The Tinnevelly-Tuticorin Electric Supply Co. Ltd. v. Its Workmen

June 25, 2025

A) ABSTRACT / HEADNOTE

This landmark decision in The Tinnevelly-Tuticorin Electric Supply Co. Ltd. v. Its Workmen, reported in (1960) 3 SCR 68, pertains to the applicability of the Full Bench Formula for payment of bonus in undertakings governed by the Electricity (Supply) Act, 1948. The central question before the Supreme Court was whether the statutory financial constraints imposed on electric supply undertakings override the workers’ entitlement to bonus under industrial adjudication principles. The Court held that electricity undertakings cannot avoid their social obligations by pleading statutory regulations and that the Full Bench Formula remains applicable for determining bonus liability, even for licensees under the Act. The judgment clarified that the bonus claim remains a matter of industrial law and must be resolved using principles such as social justice and fair profit-sharing, not solely on the financial norms of the Electricity Act. The decision stands as a precedent affirming workmen’s rights to industrial justice within regulated sectors.

C) INTRODUCTION AND BACKGROUND OF JUDGEMENT

This case arose out of an industrial dispute regarding additional bonus claims by workmen of an electric supply company functioning under the Indian Electricity Act, 1910 and the Electricity (Supply) Act, 1948. The appellant company contended that the statutory restrictions on profits and tariffs under the Act precluded any claim to bonus by workmen beyond the regulatory framework. The claim raised significant questions about the interplay between statutory regulation and industrial jurisprudence. Prior decisions by Labour Appellate Tribunals had shown inconsistency, leading to the formation of a Special Full Bench to resolve the legal dilemma authoritatively. The Court’s judgment provided definitive clarity on the applicability of labour principles to statutory undertakings.

D) FACTS OF THE CASE

The Tinnevelly-Tuticorin Electric Supply Co. Ltd. was licensed by the Madras Government under the Indian Electricity Act, 1910 and regulated by the Electricity (Supply) Act, 1948. It purchased power from the State Hydro-electric Projects and supplied it to specific municipal areas. Its workmen made several demands, including a claim for additional bonus for the year 1952-53. The company had already paid two months’ bonus voluntarily but resisted further payment, contending that such claims were untenable under the Sixth Schedule of the Electricity (Supply) Act, 1948. The Industrial Tribunal initially accepted the workmen’s claim and awarded further bonus. Upon appeal, the Labour Appellate Tribunal modified the quantum to one month’s additional basic wage but affirmed the legal applicability of the Full Bench Formula in determining bonus.

E) LEGAL ISSUES RAISED

i. Whether the workmen of electricity undertakings regulated under the Electricity (Supply) Act, 1948 are entitled to bonus determined through industrial adjudication.

ii. Whether the Full Bench Formula is applicable to calculate bonus for such undertakings.

iii. Whether the Electricity Act’s financial ceiling, including the ‘reasonable return’ and ‘clear profits’, overrides industrial law obligations to pay bonus.

iv. Whether such bonus claims can be treated as legitimate expenditure under Paragraph 17(2)(b)(xi) or (xiii) of the Sixth Schedule.

F) PETITIONER/ APPELLANT’S ARGUMENTS

i. The counsels for Petitioner / Appellant submitted that the Electricity (Supply) Act, 1948 was a complete code and specifically regulated the earnings, expenses, and distribution of profits for electricity licensees. The workmen’s claim for bonus, therefore, must conform strictly to the financial limitations of the Sixth Schedule. According to the company, only excess profits beyond the ‘reasonable return’ could be considered for bonus. Relying on this interpretation, they argued that industrial adjudication through the Full Bench Formula, which applies to commercial undertakings, should not bind statutory utilities like the appellant. They stressed that applying the Full Bench Formula would contradict legislative intent and create financial instability in essential services regulated by law.

G) RESPONDENT’S ARGUMENTS

i. The counsels for Respondent submitted that bonus, being part of social justice, must not be denied solely due to financial restrictions under the regulatory law. They argued that electricity undertakings are not excluded from the operation of the Industrial Disputes Act, 1947, and the labour courts were competent to determine bonus using the Full Bench Formula. They further submitted that profits shown in the company’s commercial accounts—not merely the working sheets prepared under the Electricity Act—should be used to assess capacity to pay. They relied on judicial precedent and the fact that bonus is allowable under the Income Tax Act, thus being an admissible expenditure even under Paragraph 17(2)(b)(xi) of the Sixth Schedule.

H) RELATED LEGAL PROVISIONS

i. Section 10(1)(c) of the Industrial Disputes Act, 1947 – Authorizes the State to refer disputes to tribunals for adjudication.

ii. Section 57 and Sixth Schedule of the Electricity (Supply) Act, 1948 – Regulates permissible profits, “reasonable return”, and clear profits of electricity licensees.

iii. Section 10(2)(vi) of the Income Tax Act – Admits bonus as a deductible expenditure.

iv. Paragraph 17(2)(b)(xi) and (xiii) of the Sixth Schedule – Lists admissible business expenses including bonus under certain conditions.

v. Baroda Borough Municipality v. Its Workmen, 1957 SCR 33 – Bonus determination remains under labour law even for statutory bodies.

I) JUDGEMENT

a. RATIO DECIDENDI

i. The Supreme Court held that the Full Bench Formula applies to electricity undertakings for adjudicating bonus claims. It clarified that the Electricity (Supply) Act, 1948 and the Sixth Schedule do not preclude the application of industrial law. The Court reasoned that the Act only restricts consumer tariffs and reasonable returns, not wage or bonus entitlements. Industrial adjudication principles continue to operate independently. Therefore, the Tribunal’s reliance on the company’s commercial profit and loss account rather than the regulated working-sheet was correct. This interpretation upheld workers’ entitlement to equitable distribution of profits and affirmed bonus as a legitimate industrial demand.

b. OBITER DICTA

i. The Court observed that financial regulations under the Electricity Act do not determine wage or bonus entitlements, which arise from broader industrial relations and labour jurisprudence. The absence of explicit wage regulations in the Act implied the continued relevance of social justice principles.

c. GUIDELINES

The claim for bonus by workmen must be adjudicated using the Full Bench Formula unless expressly excluded by statute.
Companies governed by special statutes must also comply with general labour welfare obligations under the Industrial Disputes Act.
The balance-sheet and commercial profit and loss accounts must be used in adjudication of bonus claims—not merely the working-sheet under the Electricity Act.
Paragraph 17(2)(b)(xi) of the Sixth Schedule includes admissible expenses like bonus under the Income Tax Act.
The subsequent addition of Paragraph 17(2)(b)(xiii) affirms the legislative intent to recognize bonus as a legitimate business expense.

J) CONCLUSION & COMMENTS

This judgment fortifies the social justice framework embedded in Indian industrial jurisprudence. It strikes a harmonious balance between statutory financial regulation and labour rights, reaffirming the applicability of the Full Bench Formula even to undertakings governed by special laws. By treating bonus as a legitimate industrial claim rather than a discretionary payout, the Court has empowered tribunals to ensure equitable treatment of workers. The judgment underlines that sector-specific statutes like the Electricity (Supply) Act, 1948 do not override broader labour rights guaranteed under the Industrial Disputes Act, 1947. It remains a seminal precedent in asserting industrial justice over narrow technical interpretations.
