The Derivative Suit, Step by Step
The corporation’s claim, brought by a shareholder
Most breach claims are the corporation’s claim.
Texas: a statutory procedure with deadlines.
Delaware: Rule 23.1.

TEXAS (TBOC)Standing, demand, demand review, then the gate
DELAWARE (DGCL + common law)Demand or demand futility, then the standard the decision carries
1. Standing
Own, keep owning, represent, and meet the threshold
The shareholder must have held shares at the time of the act or omission (or taken them by operation of law from one who did), must fairly and adequately represent the corporation, and, for a corporation with listed common shares or an electing corporation with 500 or more shareholders, must at the time of filing beneficially own the number of shares the certificate or bylaws require, not more than three percent of the outstanding shares, with aggregation across holders allowed.1 The statute says “institute or maintain”: a holder cashed out mid-case loses standing.
Applied. A federal court dismissed a 100-share Southwest Airlines holder under a three-percent bylaw adopted two days after S.B. 29 took effect.
2 To sue on the company’s behalf a shareholder must have owned shares at the time, keep owning them, fairly represent the company, and, at a listed or opted-in company, meet any ownership threshold the company set, up to three percent of all shares; several holders can pool their shares. A federal court has already thrown out a 100-share holder under a three-percent bylaw.
Own, keep owning, represent
Contemporaneous and continuous ownership and adequate representation under Rule 23.1; a stockholder cashed out in a merger loses derivative standing, which is one reason merger claims are pleaded as direct where the injury and remedy are the stockholder’s (sheet 09).3
Delaware requires the same ownership and representation. A shareholder cashed out in a merger can no longer sue on the company’s behalf, which is why merger claims are brought directly.
2. Demand
Written demand, then 91 days
A written demand stating the matter with particularity must precede suit, and the suit may not be filed until the 91st day after the demand unless the demand is rejected or waiting would cause irreparable injury.4 Demand is universal; there is no futility exception for a corporation this sheet covers (the closely-held exception is sheet 09).5
The shareholder must first send a written demand and wait 91 days, unless the board rejects it sooner or the delay would cause irreparable harm. There is no ‘demand would be futile’ shortcut.
Demand, or plead futility
Demand on the board, or particularized facts that it would be futile: for at least half the demand board, a material personal benefit, a substantial likelihood of liability, or lack of independence from someone who has either.6 Exculpated care claims alone do not supply the likelihood of liability.
The shareholder must demand that the board sue, or plead specific facts that at least half the board could not decide fairly.
3. Demand review
Independent directors, a committee, or a court panel; an optional 45-day hearing
The determination how to proceed is made by a majority of the independent and disinterested directors, a committee of them, or a court-appointed panel.7 The corporation may petition for a judicial determination of their independence; the hearing is due within 45 days and the ruling within 75, each extendable for good cause, and the ruling is dispositive of that question absent facts not presented.7 A good-faith determination after reasonable inquiry that continuing the suit is not in the corporation’s interest requires dismissal on the corporation’s motion, with the burden allocated by § 21.558(b).7
Independent directors, a committee of them, or a court-appointed panel decide whether the company should pursue the claim. The company can ask the court to rule on their independence; the hearing is due within 45 days and the ruling within 75, unless the court extends for good cause, and the ruling sticks unless new facts emerge. A good-faith decision not to sue, after reasonable inquiry, ends the case on the company’s motion.
Refusal, or a special litigation committee
A rejected demand is reviewed for whether the refusal was itself a valid business judgment; a special litigation committee may move to dismiss under Zapata’s two steps, the second of which is the court’s own discretionary judgment.8 These are judgments about pursuing the claim, not about the original decision.
If the board refuses a demand, the court asks whether the refusal was itself a reasonable business decision; a special committee can move to dismiss under a two-step review.
4. The merits gate
§ 21.419, if the corporation is covered
PLEADparticularity on fraud, intentional misconduct, ultra vires or knowing violation.9
REBUTat least one presumption.10
BREACHcare, loyalty or obedience, by its common-law content (sheet 02).11
PLUSthat the breach involved one of the four.9
CONFLICT§ 21.418(f): a safe-harbor miss still routes here.12
Open. How the particularity requirement interacts with a Rule 91a motion to dismiss is the first unresolved procedural question.
13 Then the merits gate: spell out one of the four grounds, knock down a presumption, prove a breach, prove the breach involved one of the four. A conflicted deal is routed here too. How this interacts with Texas’s early-dismissal rule is not yet decided.
The standard the decision carries
PLEADfacts rebutting the presumption, or facts invoking Unocal, Revlon or entire fairness.14
SHIFTthe board justifies itself under the applicable standard.15
SAFE HARBOR§ 144 for a conflicted deal.16
EXCULPATE§ 102(b)(7) for directors; for officers, not on a derivative claim.17
Then the merits: plead facts that rebut the presumption or invoke a stricter test; the board justifies itself; the safe harbor applies to conflicted deals; the charter clause applies to directors but not to officers on this kind of claim.
5. Remedies and defenses
To the corporation
Damages or disgorgement, the latter without proof of loss once a fiduciary’s secret benefit taken in breach is proven.18 Subject to a § 7.001 exculpation clause, which § 21.419(g) preserves, and to the stacked common-law defenses § 21.419(e) preserves.1920 Exclusive-forum and jury-waiver provisions apply if adopted.21
Any recovery goes to the company: damages, or disgorgement of a secret benefit without proof of loss. A charter clause can limit the damages, and other defenses still apply.
To the corporation
Damages for non-exculpated breaches; rescissory damages and disgorgement in loyalty cases; a controller’s monetary liability confined to specified kinds of wrongdoing by § 144(d)(5); aiding-and-abetting liability for knowing participants.1622
Any recovery goes to the company: damages for non-excused breaches, disgorgement in disloyalty cases, controller liability limited to specified kinds of wrongdoing, and liability for buyers who knowingly helped.
THE TEXAS DERIVATIVE SUIT IS A STATUTORY TRACK WITH A CLOCK.Demand is universal, the optional independence hearing runs on a 45-day timetable, the ownership threshold can be three percent, and the merits gate is § 21.419. Delaware’s track is judge-made at every step, and exculpation or demand failure can end it early.
