Sheikh Tahnoon Bin Saeed Bin Shakhboot Al Nehayan v Kent

An informal, long-term joint venture may carry an implied duty of good faith where necessary to give effect to reasonable expectations. That duty permits pursuit of self-interest but prohibits contextually unacceptable opportunism. Mutual trust alone does not create fiduciary duties: fiduciary loyalty depends on an undertaking to act on another’s behalf. Duress may arise from unjustified demands reinforced by otherwise lawful pressure, or from threats of violence. Violence need only be a reason for entering the contract, and the same causation standard applies to intimidation. Duress itself is not necessarily tortious. Where payment of a contractual debt would generate an equal damages liability for inducing it, circuity of action defeats the claim.

Sheikh Tahnoon invested in hotel and online travel businesses established or managed by Mr Kent. Their joint venture operated through companies, initially owned equally. Further investment increased the Sheikh’s interest to 70%. Mr Kent managed the businesses and personally guaranteed company liabilities.

When the businesses faced collapse, representatives of the Sheikh negotiated a demerger. A Framework Agreement separated the parties’ interests and imposed payment obligations and indemnities on Mr Kent. An accompanying promissory note required him to pay €5.4m. The Sheikh sought payment under both agreements.

Mr Kent disputed the Framework Agreement claims and counterclaimed for relief arising from alleged fiduciary duties, contractual duties and duress. He alleged that the Sheikh’s representatives blocked a proposed rescue transaction with FTI, a tour operator, and threatened violence to secure his agreement. Claims for rescission were ultimately abandoned. The court therefore considered contractual liability, the duties arising from the joint venture, and whether actionable wrongdoing supplied a damages claim or defence to payment.

1. The claim failed. No sum was proved due under the Framework Agreement. Although the Sheikh otherwise had a damages claim for the value of the promissory note, payment would generate an equal liability on Mr Kent’s counterclaim. Neither party could recover money from the other.

2. The Framework Agreement required construction in its commercial context. References to payments to the Sheikh meant funding or liabilities of Investors, the hotel-owning company, while he owned it. Alternatively, acceptance of direct company payments constituted a written waiver of personal payment. Additional-debt claims required proof of an ascertained liability within the indemnity’s temporal and substantive limits. The grant indemnity required proof that, but for an attributable act or omission, payment would have been received during the Sheikh’s ownership. Those requirements were unproved. Accepted anticipatory repudiation entitled the Sheikh to the promissory note’s future payments, with appropriate discounting.

3. The Sheikh had undertaken no continuing obligation to fund the businesses. The parties were shareholders rather than legal partners. Fiduciary duties had to accommodate their contractual relationship. Trust and friendship alone were insufficient: the Sheikh had undertaken no discretionary role on Mr Kent’s behalf and could assess investment decisions in his own interests. The claim for an account of profits therefore failed.

4. The informal venture was nevertheless a relational contract involving long-term collaboration, interlinked interests and substantial mutual trust. Good faith was implied through business necessity and, independently, because the relationship’s nature required it absent contrary indication. It required honesty, fidelity to the bargain and contextually acceptable fair dealing, without fiduciary subordination of self-interest. Concealed negotiations to sell the Sheikh’s shares breached that duty but were unpleaded and caused no loss. Using shareholder control to block the only available rescue unless Mr Kent accepted unjustified personal payment obligations was actionable opportunism.

5. Duress required illegitimate pressure inducing agreement. Lawful threatened action could qualify where the demand lacked reasonable grounds and reasonable and honest people would regard its reinforcement as improper. Unconscionability remained a high threshold. Economic duress ordinarily required but-for causation; threats of violence needed only to contribute to the decision: Barton v Armstrong [1976] AC 104, applied. Legal advice and rational submission did not preclude duress. The physical threats contributed to Mr Kent’s agreement. The Sheikh was vicariously liable for his agents’ conduct during negotiations despite lacking knowledge or authority. No finding of duress rested on the unpleaded litigation threats.

6. Duress supplied rescission and restitution but did not necessarily constitute a tort. The note was inseparable from the demerger and could not be rescinded alone. Damages instead arose from breach of good faith and intimidation. Intimidation encompassed actual unlawful coercion, including blackmail, as well as unlawful threats. The reduced causation threshold for violence applied equally to that tort. Mr Kent proved no further loss and obtained no identifiable financial benefit requiring credit. Circuity of action consequently defeated recovery under the note.

• High Court (Commercial Court): First instance proceedings begun in July 2013 under the Framework Agreement. A promissory-note claim was subsequently added. Mr Kent amended his defence and counterclaim to allege duress and seek rescission, but ultimately abandoned rescission and pursued damages and an account of profits. Following trial, neither party was entitled to recover money.
