Kenya Concrete, Structural, Ceramic Tiles, Woodplys & Interior Design Workers Union v Bomi Engineering and Construction Company
The bottom line
#Kenya's Employment Court confirmed that trade unions can sue for their members, and employers cannot use new 2024 procedural rules to strike out older cases.
What this practically means
#Executive summary
#Key legal issues
#Locus standi of a trade union to sue on behalf of members
A trade union has locus standi to institute claims on behalf of its members under Article 22(2)(d)/258(2)(d) of the Constitution and Section 22 of the ELRC Act
Relying on the Court of Appeal's Modern Soap Factory decision, the court held that Article 41 protects the right to join a trade union, and an association acting in the interest of its members may institute proceedings. Section 22 of the ELRC Act permits representation by an office bearer or official of the party's trade union. The union's suit was therefore properly instituted.
Compliance with Rule 63 of the ELRC (Procedure) Rules 2024
The 2024 Rules did not apply to a suit filed in 2023 under the 2016 Rules; retrospective application is impermissible
The suit was filed on 26th September 2023 when the 2016 Rules were in force. The 2024 Rules commenced on 16th August 2024. The court held that law does not operate in retrospect, so the Claimant could not be accused of non-compliance with rules that did not exist when the suit was filed.
Proof of union membership at interlocutory stage
Allegation that grievants are not bona fide members is premature and can only be determined upon evidence at trial
The court noted that a Recognition Agreement and CBA had been signed by the parties, indicating the union had membership in the company. Following Modern Soap Factory and Mukisa Biscuit, contested questions of membership are questions of fact requiring evidence, not determinable on a preliminary objection or striking-out application.
Procedural technicalities versus substantive justice
The court is obligated under Article 159(2)(d) and Section 20(1) of the ELRC Act to administer justice without undue regard to procedural technicalities
The court invoked Article 159(2)(d) of the Constitution and Section 20(1) of the ELRC Act, which require the court to act without undue regard to technicalities. The Claimant had since appointed counsel, and the pleadings demonstrated a dispute capable of determination, so striking out would defeat substantive justice.
Legal principles established
#- A law cannot be applied retrospectively; a party cannot be faulted for non-compliance with rules that did not exist when the suit was filed
- Whether an employee is a member of a union is a question of fact requiring evidence, not amenable to determination by preliminary objection
- The burden of proving that a suit is incompetent and frivolous lies on the party asserting it
Court orders
#- 1.The Respondent's Notice of Motion dated 13th November 2025 is dismissed with costs to the Claimant
- 2.The suit is fast-tracked and set down for hearing/trial on priority basis unless resolved by consent
- 3.The Respondent to file and serve all its pleadings within fourteen (14) days if not already done
- 4.Any party wishing to file further documents, witness statements or amend pleadings to do so within twenty-one (21) days of the date of the Ruling
- Jurisdiction invoked
- Article 162(2) Constitution / Employment and Labour Relations Court Act (court's specialised jurisdiction); application under Rule 63 ELRC (Procedure) Rules 2024 and Section 22 ELRC Act
