“5 Meaning of ‘independent trade union’ In this Act an ‘independent trade union’ means a trade union which – (a) is not under the domination or control of an employer or group of employers or of one of more employers’ associations, and (b) is not liable to interference by an employer or any such group or association (arising out of the provision of financial or material support or by any other means whatsoever) tending towards such control; and references to ‘independence’, in relation to a trade union, shall be construed accordingly.”
“If any proceedings before a court, the Employment Appeal Tribunal, the Central Arbitration Committee, ACAS or an employment tribunal a question arises whether a trade union is independent and there is no certificate of independence in force and no refusal, withdrawal or cancellation of a certificate recorded in relation to that trade union – (a) that question shall not be decided in those proceedings, and (b) the proceedings shall instead be stayed or sisted until a certificate of independence has been issued or refused by the Certification Officer. (5) The body before whom the proceedings are stayed or sisted may refer the question of the independence of the trade union to the Certificate Officer who shall proceed in accordance with section 6 as on an application by that trade union.”
