National Union of Metal Workers of South Africa v Lufil Packaging (Isithebe) and Others

NUMSA sought organisational rights under sections 12 to 16 of the Labour Relations Act 66 of 1995 at Lufil Packaging’s workplace. Although NUMSA claimed to represent about 70% of Lufil’s employees, Lufil operates in the paper and packaging industry, which falls outside NUMSA’s registered scope as defined in its constitution. NUMSA nevertheless admitted Lufil employees as members. Lufil refused organisational rights, arguing that NUMSA acted ultra vires its constitution and that the employees were not lawfully eligible members. The CCMA and Labour Court ruled in NUMSA’s favour, but the Labour Appeal Court overturned those decisions, holding that NUMSA could not rely on members admitted contrary to its constitution. NUMSA sought leave to appeal to the Constitutional Court.

The application for leave to appeal was dismissed. Each party was ordered to pay its own costs.

The case clarifies that trade unions in South Africa are bound by their own constitutions when claiming organisational rights. It confirms that representativity under the LRA must be based on lawfully admitted members and affirms the constitutionality of section 4(1)(b) of the LRA. The decision reinforces orderly collective bargaining and limits unions’ ability to expand their scope informally.
