Trade Union and Labour Relations (Consolidation) Act 1992

160 Awards against third parties

(1) If in proceedings before an industrial tribunal on a complaint of unfair dismissal either the employer or the complainant claims—

(a) that the employer was induced to dismiss the complainant by pressure which a trade union or other person exercised on the employer by calling, organising, procuring or financing a strike or other industrial action, or by threatening to do so, and

(b) that the pressure was exercised because the complainant was not a member of any trade union or of a particular trade union or of one of a number of particular trade unions,

the employer or the complainant may request the tribunal to direct that the person who he claims exercised the pressure be joined or sisted as a party to the proceedings.

(2) The request shall be granted if it is made before the hearing of the complaint begins, but may be refused after that time; and no such request may be made after the tribunal has made an award of compensation for unfair dismissal or an order for reinstatement or re-engagement.

(3) Where a person has been so joined or sisted as a party to the proceedings and the tribunal—

(a) makes an award of compensation for unfair dismissal, and

(b) finds that the claim mentioned in subsection (1) is well-founded,

the tribunal may order that the compensation shall be paid by that person instead of the employer, or partly by that person and partly by the employer, as the tribunal may consider just and equitable.
