Summary
Landmark Cases in Fiduciary Law: A Study Guide
Introduction
Fiduciary law establishes a fundamental principle: those entrusted with managing assets or making decisions on behalf of others must prioritize those they serve above their own interests. The landmark cases you're studying form the backbone of this doctrine across common law jurisdictions. Understanding these cases means grasping a few core principles—the duty of loyalty, the prohibition on self-dealing, the corporate opportunity doctrine, and the standards for care—rather than memorizing individual decisions. This guide walks you through the most important cases, organized by the principles they establish, so you can see how fiduciary law developed and why each principle matters.
The Foundation: The Duty of Loyalty and Prohibition on Profit
Keech v Sandford (1726) – The Cornerstone
Why this case matters: Keech v Sandford is perhaps the most fundamental case in fiduciary law. It established a rule that still governs fiduciary relationships today: a fiduciary cannot profit from opportunities that arise from their position, even if the beneficiary could not have taken that opportunity themselves.
In this case, a trustee held a lease for a beneficiary's estate. When the lease came up for renewal, the landlord refused to renew it for the beneficiary (likely because the beneficiary was a child and thus lacked legal capacity). The trustee then obtained the renewed lease in their own name, profiting from the renewal. The court held this was a breach of fiduciary duty and ordered the trustee to hold the new lease for the beneficiary's benefit.
The key insight here is that the trustee's personal profit motive meant they couldn't act with the impartiality required of a fiduciary. Even though the beneficiary couldn't legally have obtained the lease themselves, the rule prevents fiduciaries from exploiting their position.
What it establishes: The duty of loyalty is absolute—a fiduciary must not allow personal profit-seeking to interfere with their obligations. There's no exception simply because the beneficiary couldn't take the opportunity.
Meinhard v Salmon (1928) – Strict Loyalty in Action
Why this case matters: Written in the United States by Judge Benjamin Cardozo, this case reinforced and expanded on Keech's principle with memorable language. It established that fiduciaries owe a strict duty of loyalty that requires them to share any opportunity arising from the fiduciary relationship.
Here, two partners in a real estate venture—Meinhard and Salmon—had worked together on a property renewal opportunity. When a similar opportunity arose involving the same property, Salmon took it for himself without offering it to Meinhard. The court held that Salmon had violated his fiduciary duty to his co-partner by appropriating an opportunity that naturally arose from their joint relationship.
Cardozo famously wrote that a fiduciary must not merely refrain from actual fraud—they must avoid even the appearance of impropriety. The standard is strict: a fiduciary is held to something "stricter than the morals of the market place."
What it establishes: The duty of loyalty is not just about avoiding obvious conflicts; it requires proactive good faith and candor. Any opportunity that arises from the fiduciary relationship should be offered to the beneficiary first.
Key distinction from Keech: While Keech involved a trustee and a single beneficiary, Meinhard involved partners with mutual fiduciary duties to each other. This expanded the principle to show that the duty operates even between parties of roughly equal bargaining power.
The Corporate Opportunity Doctrine
The cases in this section apply loyalty duties specifically to corporate directors and officers, developing what's known as the corporate opportunity doctrine.
Regal (Hastings) Ltd v Gulliver (1942) – Corporate Opportunities Belong to the Corporation
Why this case matters: This UK House of Lords case established that directors cannot appropriate opportunities that rightfully belong to the corporation. The directors of a company learned of an opportunity to acquire shares in a subsidiary company. Rather than having the corporation pursue this opportunity, they personally purchased the shares, profiting when the subsidiary later succeeded.
The court held they had breached their fiduciary duty. Even though the corporation might not have been able to pursue the opportunity on its own, the fact that the directors learned of it through their position meant it belonged to the corporation. They were obligated to disclose the opportunity to the corporation and obtain formal consent (or ensure the corporation could not take it) before pursuing it themselves.
What it establishes: Under the corporate opportunity doctrine, a corporate fiduciary cannot take a business opportunity that belongs to the corporation, even if the corporation lacks the capital or capacity to pursue it independently. The opportunity must be offered to the corporation first.
Guth v Loft Inc. (1939) – When Does an Opportunity "Belong" to the Corporation?
Why this case matters: This American case developed an important test for determining when an opportunity is a corporate opportunity. Guth, a corporate officer, learned of an opportunity to acquire a soft drink formula while acting in his corporate role. He pursued it personally instead of offering it to his employer, Loft Inc.
The court held that an opportunity is a corporate opportunity if:
The fiduciary learned of it in their corporate capacity or through corporate resources
The corporation had a reasonable expectancy or interest in the opportunity
The opportunity was one the corporation was financially able to undertake
This three-part test helps distinguish between opportunities that truly belong to the corporation and personal opportunities a fiduciary happens to learn about.
What it establishes: Not every business opportunity an officer hears about is a corporate opportunity. The opportunity must have some genuine connection to the corporation's business, resources, or financial capacity.
Key distinction from Regal: While Regal emphasized that corporations have priority over directors, Guth recognizes that directors do have some personal business opportunities. The test prevents an overly broad reading of fiduciary duty that would eliminate all personal entrepreneurship by corporate officers.
The Complication: Profit Derived from Position, Not Opportunity
Boardman v Phipps (1966) – Accounting for Profits from Information
Why this case matters: This case presents a tricky issue: What if a fiduciary uses information obtained through their position to generate profits, but the beneficiary couldn't have used that information anyway?
Boardman and Phipps were solicitors for a trust. Through their work, they gained information about a company owned by the trust. Using this information, they orchestrated a takeover of the company that was highly profitable for themselves. The beneficiaries sued, claiming breach of fiduciary duty.
The court faced a genuine puzzle. Unlike Keech (where the same property was involved) or Meinhard (where both parties had equal rights), here the beneficiaries owned shares in the trust but the trust couldn't actively manage the company. Should the fiduciaries be prohibited from profit-making entirely, or something else?
The court held that the fiduciaries had breached their duty by not obtaining informed consent—but it didn't strip them of all profits. Instead, it ordered them to account for (share) the profits they made. This was a middle ground: the fiduciaries couldn't hide their profits, but they weren't entirely stripped of them because they had done useful work.
What it establishes: Information obtained in a fiduciary position is trust property. A fiduciary cannot freely use it for personal profit. However, if a fiduciary can show they obtained proper informed consent from the beneficiary, or in some cases that the beneficiary couldn't have used the information, they may be allowed to retain some or all of the profits.
The important distinction: This is not permission to profit without accounting. It's recognition that sometimes a fiduciary's unauthorized use of trust information doesn't justify complete disgorgement if the circumstances warrant it. Most modern cases still follow the strict rule from Keech and Meinhard that fiduciaries should not profit without consent.
Fiduciary Duties Beyond Loyalty: Care and Good Faith
Mothew v Bristol & West Building Society (1996) – Fiduciary Duty Is About Good Faith, Not Mere Competence
Why this case matters: Students often confuse fiduciary duties with ordinary duties of care. This case clarifies the distinction. Mothew was a mortgage broker who made negligent mistakes in his work. The question was whether this negligence constituted a breach of fiduciary duty.
The court held that a breach of fiduciary duty requires a failure to act in good faith, not merely a breach of the duty of care. Being negligent or incompetent is not the same as being a faithless fiduciary. A fiduciary can be sloppy and still technically fulfill their fiduciary duty, though they might breach other legal duties (like the duty of care in contract or tort).
What it establishes: Fiduciary duty focuses on loyalty and good faith—acting without conflicts of interest and being honest. While fiduciaries also owe duties of competence and care, those are separate from fiduciary duty itself. A breach of duty of care is not automatically a breach of fiduciary duty.
Why this matters for exams: You may see scenarios where a fiduciary makes a bad decision. Ask yourself: Did they act in bad faith or with a conflict of interest? If not, it's a breach of the duty of care, not the fiduciary duty. Conversely, you might see a fiduciary act competently but selfishly—that's a fiduciary breach.
The Special Context: Shareholder Interests in Corporate Sales
<extrainfo>
Revlon, Inc. v MacAndrews & Forbes Holdings, Inc. (1985) – Directors' Duty When Selling the Company
Why this case matters: Once a corporation enters a "sale mode"—where the goal shifts from running the ongoing business to obtaining the best sale price—directors enter what's called the "Revlon stage" or "Revlon duty." At this point, the board's primary duty is to maximize shareholder value through the sale process.
In Revlon, the corporation faced multiple bidders for acquisition. The board favored one bidder, then changed course. The court held that once the corporation decided to sell, the directors couldn't simply pursue their preferred buyer—they had to conduct a fair auction and seek the highest price for shareholders.
What it establishes: In the context of a corporate sale, the duty of loyalty shifts focus to maximizing shareholder value (the sale price), not protecting management's interests or preferring particular buyers.

Disclosure and Informed Consent
In Plus Group Ltd v Pyke (2002) – Informed Consent Must Be Real
Why this case matters: Several cases establish that fiduciaries can sometimes avoid breaching their duties through informed consent. But what counts as "informed"? In this case, a director and shareholder of a company engaged in self-dealing transactions without fully disclosing the extent of his conflicts to other shareholders.
The court held that informed consent requires complete, honest, and timely disclosure of all material facts about the conflict. A vague disclosure that leaves shareholders guessing is insufficient.
What it establishes: Informed consent is a genuine defense to fiduciary breach, but only if truly informed. This reinforces that fiduciaries can't hide conflicts and expect blessing from beneficiaries.
Fiduciary Duties in Insolvency and Broader Contexts
<extrainfo>
Pilmer v Duke Group Ltd (in liquidation) (2001) – Fiduciary Duties to Creditors
Why this case matters: When a company becomes insolvent, the question arises: To whom do directors owe fiduciary duties? This Australian case held that directors continue to owe fiduciary duties even during insolvency, but the beneficiary of those duties shifts. Instead of maximizing shareholder value, directors must act in the best interests of creditors as a collective group.
This doesn't eliminate the fiduciary duty—it redirects it toward protecting those most vulnerable to the corporation's failure.

Summary: The Core Principles Across All Cases
As you prepare for exams, remember that these cases all reinforce a few fundamental principles:
1. The Duty of Loyalty Is Absolute. From Keech v Sandford onward, fiduciaries cannot profit from their position without consent. This isn't a flexible rule with many exceptions—it's foundational.
2. The Standard Is Strict. As Meinhard v Salmon emphasized, fiduciaries are held to "something stricter than the morals of the market place." They can't just avoid actual fraud; they must avoid even the appearance of impropriety.
3. Opportunities From the Fiduciary Position Belong to the Beneficiary. Whether it's a lease (Keech), a business opportunity (Regal, Guth, Meinhard), or information (Boardman), anything arising from the fiduciary position must be disclosed and offered to the beneficiary first.
4. Informed Consent Is a Real Defense. If a fiduciary fully discloses a conflict and the beneficiary freely consents, the fiduciary may be relieved from liability. But the consent must be genuine and informed.
5. Self-Dealing and Conflicts of Interest Are Prohibited. Across all jurisdictions—UK, US, Australia, Canada, New Zealand—the principle is consistent: fiduciaries cannot put themselves in positions where their personal interests conflict with their duties.
6. Fiduciary Duty Is Distinct from Ordinary Negligence. Acting incompetently is not the same as breaching fiduciary duty, though it may breach other legal duties.
