Owners succeeded in avoiding an agreement settling a repair Yard’s invoice (albeit in ‘full and final’ terms, acknowledging satisfaction with work and that no claims could ensue) on the grounds of economic duress. The Tribunal found both the Yard’s insistence on a non-contractual waiver and the threat of exercising a non-contractual lien (thereby preventing the ship’s sailing), to be unlawful and amounting to illegitimate pressure. It was open to Owners to pursue their claims for delayed completion and disputed amounts (which largely succeeded) and loss of profit (which failed, the daily delay penalty sufficing).
