Article 24(4) of the Arbitration Act, which allows parties to arbitration proceedings to be represented by 'any other person of their choice', permits representation by labour consultants. Section 92 of the Labour Act, which limits representation before the Labour Court to legal practitioners or trade union officials, does not apply to arbitration proceedings. There is no inconsistency between section 92 of the Labour Act and Article 24(4) of the Arbitration Act because they govern representation in different forums. The powers conferred on arbitrators under section 98(9) of the Labour Act ('the same powers as the Labour Court') refer to substantive and jurisdictional powers outlined in section 89, not to procedural matters such as who may represent parties. Where statutory language is clear and unambiguous, courts should apply its ordinary meaning without departing from the natural grammatical sense of the words used.
