Royal Brunei Airlines Sdn Bhd v Tan [1995] 2 AC 378
Royal Brunei Airlines Sdn Bhd v Tan established dishonesty as the central fault requirement for accessory liability in breach of trust. The assistant may be liable even if the trustee acted honestly.
Facts
Royal Brunei appointed Borneo Leisure Travel as its agent to sell passenger tickets. Under the agreement, money received for the airline was to be held in trust until accounted for. Mr Tan was Borneo Leisure's managing director and principal shareholder. He caused or permitted the company to use ticket proceeds for its general business rather than keep them for the airline. Borneo Leisure later became insolvent and could not repay the money. Royal Brunei sued Tan personally for assisting the company's breaches of trust. There was no finding that the corporate trustee itself had acted dishonestly, so the case raised whether dishonesty by the accessory was sufficient.
Legal Issue
What degree of fault makes a person liable for assisting a breach of trust, and must the trustee's own breach also be dishonest before accessory liability can arise?
Held
The Privy Council held Tan liable for dishonest assistance. Lord Nicholls explained that the accessory's dishonesty is the touchstone; the trustee's breach need not itself be dishonest. A person is dishonest when their conduct falls below the objective standards of honest people, assessed in light of what that person actually knew about the transaction. At that stage the judgment rejected a negligence-based test and focused on conscious impropriety. Tan knew that the ticket proceeds belonged to Royal Brunei and deliberately participated in using them as working capital. Later decisions, especially Ivey v Genting Casinos, refined the modern dishonesty approach, but Royal Brunei remains foundational for the elements of accessory liability.
⭐ Legal Principle
A person who dishonestly assists a breach of trust or fiduciary duty may incur personal liability even though the primary wrongdoer acted honestly. Dishonesty is assessed objectively after determining the defendant's actual knowledge or belief about all the relevant facts.
Significance
Royal Brunei redirected accessory liability away from whether the trustee was dishonest and towards the assistant's own conduct. The knowledge required for dishonesty was later debated in Twinsectra Ltd v Yardley and clarified through Ivey v Genting Casinos and subsequent authority: the defendant's belief about facts is found subjectively, then honesty is judged by objective standards. The claim is personal rather than proprietary and differs from knowing receipt, which requires receipt of trust property for the defendant's benefit.
Common exam questions about this case
Must the trustee have acted dishonestly before an assistant can be liable?
No. A breach of trust may be committed honestly, yet a third party who knowingly participates can act dishonestly. Royal Brunei places the fault inquiry on the assistant. The claimant must still establish an underlying breach and assistance, but dishonesty by the primary trustee is not an additional requirement.
How is dishonesty assessed after Royal Brunei and Ivey?
The court first determines the defendant's actual knowledge or belief about the facts. It then asks whether the conduct was dishonest by the objective standards of ordinary decent people. The defendant need not appreciate that those standards would label the conduct dishonest, although an honest belief in different facts may change the assessment.
How does dishonest assistance differ from knowing receipt?
Dishonest assistance depends on participation in another person's breach and dishonest conduct; the assistant need not receive trust property. Knowing receipt requires beneficial receipt of property transferred in breach of trust and knowledge making retention unconscionable. They are distinct forms of personal equitable liability with different elements.
