AMCU, as the majority union in the workplace of Lonmin (Western and Eastern Platinum Limited), concluded an agency shop agreement with Lonmin on 24 April 2019. The agreement provided that Lonmin would deduct an agency fee from wages of all employees within the bargaining unit at Marikana Operations who were not members of AMCU. The applicants (UASA, Solidarity, and NUM) had members who were employees within this bargaining unit. On the same day, the Registrar of Labour Relations gave notice of intention to cancel AMCU's registration as a trade union on the basis that AMCU had ceased to function in terms of its constitution. The applicants only received a copy of the agency shop agreement on 22 May 2019 and launched this application on 29 May 2019, seeking a declaration that the agency shop agreement was invalid and unenforceable. Specifically, clause 7.1 of the agreement stated that 'employees who are not members of any trade union shall not be compelled to become members of AMCU', rather than stating that employees who are not members of AMCU are not compelled to become members of AMCU.
