The ITF 'blacked' a flag-of-convenience vessel at Milford Haven, compelling the shipowners to pay $80,000 including $6,480 to a Welfare Fund. The shipowners sought recovery of the Welfare Fund contribution on grounds of resulting trust or economic duress. The House of Lords held there was no trust, but the demand was not connected with terms and conditions of employment, constituting recoverable economic duress.
Facts
Universe Tankships Inc of Monrovia owned the Liberian-registered tankship ‘Universe Sentinel’. In July 1978, the vessel arrived at Milford Haven to discharge cargo. The International Transport Workers Federation (ITF), pursuing its campaign against ‘flag of convenience’ vessels, procured tugboat crews to ‘black’ the vessel, preventing it from leaving port. The ITF demanded that the shipowners enter into agreements improving crew terms and pay $80,000, including $6,480 as a contribution to the Seafarers’ International Welfare Protection and Assistance Fund. Under severe commercial pressure, the shipowners complied with these demands. After the vessel sailed, they sought to recover the payments.
Issues
The Trust Point
Whether the $6,480 paid to the Welfare Fund was held by ITF upon trusts that were void, creating a resulting trust in favour of the shipowners.
The Duress Point
Whether the payment was extracted by economic duress and, if so, whether such duress was legitimised by the statutory immunities afforded to acts done in contemplation or furtherance of a trade dispute under the Trade Union and Labour Relations Act 1974.
Judgment
The Trust Point
The House of Lords unanimously held that the Welfare Fund was not held on trust. Lord Russell of Killowen concluded that the fund was simply part of ITF’s general assets, subject to contractual arrangements between member unions under the ITF constitution. There was no trust impressed upon the fund by its rules.
The Duress Point
The House divided 3-2 on this issue. The majority (Lord Diplock, Lord Cross of Chelsea, and Lord Russell of Killowen) held that the demand for contributions to the Welfare Fund was not connected with terms and conditions of employment within section 29(1) of the Trade Union and Labour Relations Act 1974. Lord Diplock emphasised that for a dispute to be ‘connected with’ terms and conditions of employment, there must be a genuine legal relationship between the demand and the employment relationship. The Welfare Fund contributions created no obligation owed by crew members to the shipowners, nor any entitlement for crew members dependent upon their employment relationship.
Lord Diplock stated that economic duress as a ground for restitution depends upon pressure exercised by illegitimate means. Where acts are protected by statutory immunity from tortious liability because done in furtherance of a trade dispute, they constitute legitimate pressure. However, where a demand lacks the necessary connection with terms and conditions of employment, the statutory protection does not apply, and the pressure remains illegitimate.
Lord Scarman and Lord Brandon of Oakbrook dissented, considering the Welfare Fund contributions to be connected with terms and conditions of employment given their inclusion within the same package of demands relating to crew employment, the wide interpretation given to that expression in previous authorities, and the potential benefit to seafarers from the Fund.
Implications
This case is significant for developing the doctrine of economic duress in English law. It established that economic pressure can vitiate consent and provide grounds for restitution where the pressure is illegitimate. The case clarified the relationship between the statutory immunities protecting industrial action and the common law of duress: immunity from tortious liability does not automatically legitimise all demands made during industrial disputes. Only demands genuinely connected with statutory protected matters benefit from such protection. The decision also confirmed that placing an illegitimate demand alongside legitimate ones in a ‘package deal’ does not convert the illegitimate demand into a protected one.
Verdict: Appeal allowed by majority (3-2). The order of Parker J was restored except for the declaration regarding resulting trusts. The shipowners were entitled to recover the $6,480 paid to the Welfare Fund as money had and received under economic duress. The ITF was ordered to pay costs.
