Fiduciary duties: care and loyalty
Directors and officers who exercise authority on behalf of a corporation may owe fiduciary duties. Delaware opinions often discuss the duty of care and the duty of loyalty, with good-faith concepts and oversight obligations forming part of the wider analysis.
Duty of care
Focuses on the decision-making process and whether fiduciaries acted with an appropriate level of information and deliberation under the applicable standard.
Duty of loyalty
Focuses on whether fiduciaries acted in the interests of the corporation and its stockholders rather than pursuing conflicting personal interests or benefits.
The legal analysis is fact-sensitive. A poor outcome does not by itself establish a fiduciary breach, and not every conflict results in liability.
Standards of review
A standard of review is the framework a court uses to evaluate challenged fiduciary conduct. It helps define the questions the Court asks and who bears particular burdens. It is not simply a score for whether a decision was good or bad.
A deferential presumption that, when applicable, generally protects informed, good-faith, disinterested board decisions from judicial second-guessing.
A context-specific, intermediate form of review used in settings such as certain defensive measures or sale-process decisions. The Court examines the board's rationale and response against the circumstances.
A demanding standard that examines fair dealing and fair price in circumstances such as certain conflicted-controller transactions. The analysis is holistic and fact-dependent.
Mergers, controllers and special committees
Merger litigation can involve disclosure, process, valuation, conflicts, deal protections and the allocation of authority among boards, stockholders and controlling investors. Where a controlling stockholder stands on both sides of a transaction or receives a non-ratable benefit, the applicable standard of review may change.
Special committees of independent directors and informed, uncoerced stockholder votes can affect the legal analysis in specific settings. The MFW litigation ↗ is a frequently studied example. Its framework should not be reduced to a generic two-box checklist; later appellate decisions and statutory amendments matter.
The 2025 amendments: DGCL §§144 and 220
Senate Substitute 1 for Senate Bill 21 became law on March 25, 2025. It materially amended two frequently litigated parts of the Delaware General Corporation Law: §144, addressing interested-director, officer and controlling-stockholder transactions, and §220, governing stockholder inspection of corporate books and records. These changes are statutory law, not merely a new judicial gloss on older cases.
For covered controller transactions, amended §144 sets out statutory safe-harbor routes. For a controller transaction that is not a going-private transaction, the statute identifies approval by a properly empowered committee of at least two disinterested directors, approval by an informed and uncoerced majority of votes cast by disinterested stockholders, or transaction fairness. A controller going-private transaction has a more demanding structure: the statutory committee and disinterested-stockholder approval procedures must both be satisfied, or the transaction must be fair. The statute has detailed definitions and conditions; this summary is not a substitute for reading the subsection itself.
The amendments to §220 also changed the inspection landscape. The statute now identifies categories of records that generally constitute books and records for inspection purposes, including specified governance materials, certain stockholder communications, board materials, financial statements, and certain agreements and questionnaires. Requests for records beyond the statutory categories face additional statutory conditions, including a compelling-need standard for certain other records. Older inspection opinions—especially KT4 Partners and AmerisourceBergen—remain important historical authorities, but should not be presented as establishing an unqualified current right to inspect emails or every document relevant to a proper purpose.
The Act includes transition provisions. Its retroactive language is subject to exceptions for certain court actions or proceedings pending or completed on or before February 17, 2025, and for books-and-records demands made by that date. The precise effect depends on the transaction, claim, filing and demand dates.
In Rutledge v. Clearway Energy Group LLC, the Delaware Supreme Court answered certified constitutional questions on February 27, 2026. It held that the §144 amendments did not unconstitutionally divest the Court of Chancery of its equity jurisdiction and that the retroactive provision did not violate the Delaware Constitution in the circumstances presented. The Court did not decide the merits of the underlying alleged overpayment claim or rule that the transaction satisfied §144.

Stockholder litigation: direct and derivative claims
For demand futility, the Delaware Supreme Court adopted a universal director-by-director test in United Food & Commercial Workers Union v. Zuckerberg (2021). For each director on the board when the complaint is filed, the court asks whether the director received a material personal benefit from the alleged misconduct, faces a substantial likelihood of liability on a claim that is the subject of the demand, or lacks independence from someone who did. If any one factor applies to at least half of the demand board, demand is excused. The older Aronson and Rales decisions remain useful background, but they are not separate current tests to apply instead of Zuckerberg.
A direct claim asserts an injury to the stockholder personally. A derivative claim asserts an injury to the corporation, with the stockholder seeking to enforce the corporation's rights. The distinction affects standing, demand requirements, litigation control, remedies and settlement approval.
Derivative litigation is governed by procedural requirements, including Court of Chancery Rule 23.1 in relevant cases. The law concerning demand, demand futility and who controls a claim is technical and changes through case law.
Board oversight and compliance systems
Oversight litigation often asks whether directors made a good-faith effort to establish and monitor reporting systems appropriate to the company's risks. Caremark, Stone v. Ritter and Marchand v. Barnhill are important authorities in this area.
These claims are demanding. A compliance failure or regulatory violation does not automatically establish director liability. The specific allegations about board-level systems, red flags, reporting and good faith are central.
Remedies and why the requested relief matters
Corporate cases may seek injunctions before a transaction closes, rescission or rescissory damages after a transaction, monetary damages, books-and-records inspection, declaratory relief or other remedies. The remedy requested can affect both jurisdiction and the practical course of a case.
