Business Judgment Rule and Fiduciary Duty Checker

Courts do not second-guess business decisions made by directors who were informed, acted in good faith, had no personal interest in the outcome and had a rational business purpose: that is the business judgment rule. If the directors had a conflict of interest, the rule does not apply, and the directors must prove that the transaction was entirely fair, unless it was fully disclosed and approved by disinterested directors or shareholders (the safe harbour). Directors who consciously fail to oversee the company, or who take a corporate opportunity for themselves, breach the duty of loyalty. Tick the facts to see which standard applies.

The decision

The directors informed themselves of all material information reasonably availableThey acted in good faith, believing it to be in the company’s best interestsNo director had a personal interest, and the board was independentThere was a rational business purpose

Special situations (tick one to test it)

A conflicted transaction: a director or controller was on both sides or benefited personallyThe directors utterly failed to set up any oversight system, or ignored red flagsA business opportunity came to a director personally

The business judgment rule applies: the decision is presumed to be proper, and the courts will not second-guess it.

Informed (duty of care): Directors must inform themselves of all material information reasonably available before deciding. Gross negligence in the process is the test (Smith v Van Gorkom).

Good faith: The decision must be made in the honest belief that it is in the corporation’s best interests.

Disinterested and independent: No director has a material personal interest in the outcome, and none is dominated by someone who does.

Rational business purpose: The court will not second-guess a decision with a rational business purpose: only a decision so one-sided that no reasonable person could think it fair is waste (Brehm v Eisner).

The standards are those of Delaware and the Model Business Corporation Act in simplified form: other states differ, and the Delaware courts apply additional frameworks to controlling shareholders and to sales of the company.
Many charters exculpate directors from money damages for breaches of the duty of care (DGCL § 102(b)(7)), but never for breaches of the duty of loyalty or for acts in bad faith.

Shows which standard a court applies to a board’s decision: the business judgment rule (informed, in good faith, disinterested, rational), entire fairness for a conflicted transaction (unless the safe harbour of disclosure and independent approval applies), the Caremark duty of oversight, and the corporate opportunity doctrine.

Common questions

What is the business judgment rule?

A presumption that directors acted on an informed basis, in good faith and in the honest belief that the action was in the company’s best interests. It protects decisions, not conflicted or uninformed ones.

What is entire fairness?

The most demanding standard of review: the directors must prove both fair dealing (timing, structure, negotiation, approval) and a fair price.

What is the corporate opportunity doctrine?

A director may not take for themselves an opportunity in the company’s line of business that it has an interest in and could afford, unless it was first offered to the company and the disinterested board declined.
