A derivative suit is an action in which a shareholder sues on behalf of the corporation itself, seeking recovery for harm done to the company by its own directors or officers. Delaware, where a majority of large US public companies are incorporated, gives the form its governing procedure: the shareholder must ordinarily demand that the board pursue the claim, and only a board's refusal, or circumstances excusing demand, lets the suit proceed, under Delaware General Corporation Law section 327. The mechanism, not the headline allegation, determines most of these cases.

What is the difference between a derivative and a direct claim?
The distinction is about who was harmed. A direct claim belongs to the shareholder for harm to the shareholder, such as a diluted vote. A derivative claim belongs to the corporation for harm to the corporation, such as an overpayment or a conflicted transaction; any recovery goes to the company, with the shareholder's benefit arriving indirectly through the share price. The Delaware Court of Chancery treats the characterization as a threshold question, and courts have dismissed suits framed as direct that pleaded only corporate harm, per the court's published decisions.
The distinction also controls who controls the case. In a direct suit the plaintiff shareholder runs the litigation; in a derivative suit the corporation is the real party in interest, which is why the board's role enters through the demand requirement.
Why must the shareholder demand board action first?
Because the board, not an individual shareholder, holds the corporation's litigation authority. Under Delaware procedure, a derivative plaintiff must make a pre-suit demand on the board unless demand would be futile. The futility test, stated in Aronson v. Lewis (Delaware Supreme Court, 1981), asks whether the plaintiff can raise a reasonable doubt that the directors are disinterested and independent, or that the challenged transaction was otherwise the product of a valid exercise of business judgment.
Futility is demanding to plead. Courts applying Aronson and its successor decisions dismiss most demand-excused theories at the pleading stage, and the cases that survive typically rest on specific facts about director ties to the challenged transaction, per Chancery decisions publishing the standard. A plaintiff who makes demand and is refused faces a second filter: the board can terminate the suit through a special litigation committee of independent directors, subject to court review under Zapata v. Maldonado (1981).
What role do Caremark claims play?
The most prominent derivative theory against boards is oversight liability, from In re Caremark International Inc. Derivative Litigation (Delaware Court of Chancery, 1996), affirmed in its essentials by Stone v. Ritter (Delaware Supreme Court, 2006). A Caremark claim alleges that directors failed to implement or monitor a board-level reporting system for legal compliance. The standard requires proof that the directors knew they were not discharging their duty or consciously disregarded it — a formulation the courts themselves have described as possibly the most difficult theory in corporate law.
Surviving Caremark claims are correspondingly rare, and the notable exception illustrates the rule: in Marchand v. Barnhill (Delaware Supreme Court, 2019), the court allowed a Caremark claim to proceed past the pleading stage where a board had allegedly failed to oversee food-safety compliance at an ice cream company facing a deadly listeria outbreak. The decision restated, rather than relaxed, the standard; it confirmed that a board must oversee mission-critical legal risks, per the opinion.
What is the procedural sequence?
The path of a Delaware derivative case, in the order the courts process it:
- Pre-suit investigation: the shareholder assembles the factual basis for standing and for demand futility.
- Demand or demand-futility pleading: the complaint must plead demand was made and refused, or facts excusing it under Aronson.
- Motion to dismiss: the corporation typically moves to dismiss on demand grounds; most cases end here.
- Discovery and, where a special litigation committee terminated the suit, Zapata review of that termination.
- Settlement or judgment: any settlement requires court approval, including a hearing on attorney-fee awards, because the corporation and other shareholders are bound.
What the procedure establishes is a system deliberately weighted toward board authority: the corporation's claim is recoverable, but only through gates the board itself staffs. Whether that weighting serves shareholders is a live policy debate; the procedure itself is settled, per the decisions cited above.
