Quick Summary

The Karnataka High Court said the word “industry” in the Trade Unions Act (TUA) should be read like the Industrial Disputes Act (IDA) because both cover labour law. A research body can be an industry even without profit motive if it runs systematic, service-giving activities. So, CMTI staff could form a trade union.

  • Core idea: Profit motive is not required; organized services can still be “industry.”
  • Result: CMTI counted as an industry; union registration was valid.

Issues

  • Does “industry” in TUA match “industry” in IDA?
  • Can R&D employees form a union under the TUA?
  • Can IDA’s later definition be read into the TUA?
  • Does lack of profit motive stop an establishment being an “industry”?

Rules

  • Pari materia reading: Where laws share subject and purpose, an unclear term in one may be read using the other.
  • No profit motive needed: If there is systematic activity rendering material services, the body can be an “industry.”

Facts (Timeline)

CASE_TITLE
  • CMTI, an R&D body in Bengaluru, worked on machine tool design, testing, inspection, and methods.
  • It was government-funded; internal income was small.
  • Employees formed “CMTI Employees’ Association” and sought trade union registration.
  • Assistant Labour Commissioner registered the association as a union.
  • CMTI objected: “we are not an industry; we are research-only; no profit motive.”
  • Cancellation was refused; CMTI filed a writ in the High Court.

Arguments

CMTI (Petitioner)

  • Pure research; not engaged in trade/commerce.
  • No profit motive; mostly grant-funded.
  • TUA “industry” should not follow IDA definition.

Employees/Registrar (Respondents)

  • Systematic services: design, testing, consultancy, know-how.
  • IDA and TUA are pari materia; use IDA meaning.
  • Profit motive is irrelevant to “industry.”

Judgment

Held
  • Pari materia: “Industry” in TUA is read in line with IDA.
  • No profit requirement: Organized services make the body an industry even without profit aim.
  • CMTI is an industry: Activities like consultancy, testing, and sales fit IDA’s industrial profile.
  • Union valid: Employees were entitled to trade union registration.

Ratio Decidendi

TUA and IDA move in the same labour field; adopt a common meaning of “industry.” Profit motive is not decisive. CMTI’s systematic services brought it within “industry,” enabling union rights.

Why It Matters

  • Sets guidance for labs, institutes, and tech bodies on union rights.
  • Stops narrow “profit-only” views of industry under labour law.
  • Promotes consistent reading across labour statutes.

Key Takeaways

  1. “Industry” under TUA aligns with IDA.
  2. Profit motive not essential for being an industry.
  3. R&D bodies giving organized services can form unions.

Mnemonic + 3-Step Hook

Mnemonic: “PARI-PROOF”PARI materia meaning; PROOF of services, not profits.

  1. Match: Use IDA meaning for TUA.
  2. Assess: Look for systematic, service activity.
  3. Decide: If yes, staff are entitled to unionize.

FAQs

Not automatically. It must show organized, systematic services with employer–employee cooperation.

Yes, if material services are given in an organized way; selling is not the only indicator.

Yes. Once the body is an industry, employees are “workmen” for union purposes under the TUA.
