Kaur v MG Rover, [2005] IRLR 40
The effect of collective agreements on the construction of an individual employment contract.
Facts
An employee was threatened with compulsory redundancy by her employer. The employee applied to court for declaratory relief that the employer was not entitled to make her compulsorily redundant. She claimed that her individual contract of employment incorporated the provisions of two previous collective agreements that were reached between the employer and trade unions. The terms of the individual contract stipulated that employment was subject to ‘collective agreements’ made with trade unions. The employer argued that the collective agreements constituted mere promises and bargaining with the trade unions, rather than a legally-enforceable agreement.
Issues
The question arose as to whether each of the two collective agreements were intended to constitute legally-binding contracts, so as to be apt for incorporation into an individual contract of employment.
Decision/Outcome
The Court held that, in the case of collective agreements between employers and trade unions, there may be provisions that were intended or not intended to give rise to legally-enforceable contractual rights between an employer and individual employee. Accordingly, in order to determine the intention of the parties’ as to whether the collective agreements were legally-binding, the Court must interpret the words of the agreement within their surrounding context and content, in order to show that the words express a binding contractual term rather than a mere aspiration. On the facts, the Court held that both of the collective agreements were worded in the context of a bargain, with the trade unions to show a commitment to aspire to a collective objective of no compulsory redundancy. This was an aspiration of a collective rather than individual character, and was not a legally-binding agreement that was apt for incorporation in the individual employee contract.

This case summary remains accurate. Kaur v MG Rover Group Ltd [2005] IRLR 40 is a Court of Appeal decision and the legal principles it establishes regarding the incorporation of collective agreements into individual contracts of employment remain good law. The key principle — that a collective agreement provision must be “apt for incorporation” and express a legally binding contractual term rather than a mere aspiration before it can be enforced by an individual employee — continues to be applied by courts and employment tribunals. There have been no subsequent statutory changes or leading cases that have overturned or materially qualified this authority. Students should note that the broader statutory framework governing collective agreements, in particular the presumption under section 179 of the Trade Union and Labour Relations (Consolidation) Act 1992 that collective agreements are not legally enforceable contracts between the parties to them (i.e. as between employer and union), remains unchanged. The Kaur principle operates at the separate question of whether particular terms, once incorporated by reference into an individual contract, are enforceable by the employee — a distinct issue from enforceability between the employer and the union.
