At a glance
SB 21 is not a general immunity statute and does not eliminate the Court of Chancery’s jurisdiction. It creates detailed statutory procedures that can limit equitable relief and damages for certain interested-director, officer and controlling-stockholder transactions, and it narrows the statutory framework for stockholder inspection demands. The text, definitions, transaction type, voting facts and transition rules all matter.
Do not apply pre-2025 cases as though the statute never changed—or assume the statute applies without checking its scope and transition provisions. The 2025 Act and older common-law authorities must be read together.
Section 144: interested directors, officers and controllers
Amended 8 Del. C. §144 addresses acts or transactions involving interested directors or officers and certain transactions involving a controlling stockholder or control group. It provides specified paths for avoiding voidability, equitable relief or damages on the grounds covered by the section. Whether a path is available depends on the precise statutory definition and whether the required process was followed.
Director and officer interests — subsection (a)
For covered director- or officer-interest transactions, subsection (a) identifies approval or ratification routes involving disclosure or knowledge of material facts and approval by disinterested directors, an appropriately constituted committee of disinterested directors, or an informed and uncoerced majority of votes cast by disinterested stockholders. The statute also addresses fairness. The precise route and its conditions should be checked in the enacted text; labels such as “independent committee” are not enough by themselves.
Controlling-stockholder transactions — subsections (b) and (c)
For a controller transaction that is not a going-private transaction, subsection (b) provides alternative paths involving a committee of at least two directors determined to be disinterested and expressly empowered to negotiate, oversee and reject the transaction; an informed, uncoerced majority-of-the-minority vote; or fairness to the corporation and its stockholders. Each route has detailed statutory conditions.
For a controller going-private transaction, subsection (c) generally requires both the qualifying committee process and the qualifying disinterested-stockholder vote, or that the transaction be fair to the corporation and its stockholders. Do not collapse the going-private and non-going-private provisions into one rule.
Definitions and limits matter
Subsection (e) defines terms including controlling stockholder, control group, control transaction, disinterested director and disinterested stockholder. The definition of controlling stockholder includes specified voting-power and management-authority routes; do not rely on an ownership percentage in isolation. Subsection (d) also contains limitations and preserves specified forms of equitable relief and claims. It is inaccurate to describe §144 as blanket immunity for controllers or directors.
Section 220: stockholder books-and-records demands
SB 21 amended 8 Del. C. §220 to define more specifically which corporate materials generally constitute statutory books and records for inspection demands. The enumerated categories include governing documents; specified stockholder minutes, consents and communications; board and committee minutes and actions; materials provided to the board or a committee in connection with its actions; certain financial statements; agreements under §122(18); and independence questionnaires for directors and officers of listed companies.
A demand still must satisfy statutory requirements, including a proper purpose, good faith, an oath, reasonable particularity and a nexus between the purpose and the requested records. The statute permits conditions concerning confidentiality and use in specified circumstances. It also sets out how the court should treat functional equivalents when certain records do not exist and provides a heightened “compelling need” path for certain records outside the enumerated categories, including a clear-and-convincing-evidence standard that the records are necessary and essential.
This matters when reading older inspection decisions. KT4 Partners and AmerisourceBergen were decided under earlier versions of §220. They remain useful for historical context and certain principles, but should not be described as establishing an unrestricted present-day right to inspect emails, informal communications or any document that might relate to a proper purpose.
Transition provisions
Section 3 states that the amendments apply to acts and transactions occurring before, on or after enactment, subject to exceptions. Among those exceptions are certain actions or proceedings commenced in a court of competent jurisdiction and completed or pending on or before February 17, 2025, and books-and-records demands made on or before that date. A case’s filing date, procedural status, transaction date and inspection-demand date may therefore affect the analysis. This is not a universal retroactivity answer for every dispute.
Rutledge v. Clearway: the constitutional questions
In Rutledge v. Clearway Energy Group LLC, No. 248, 2025 (Del. Feb. 27, 2026), the Delaware Supreme Court answered two certified questions. It held that the §144 amendments did not violate the Delaware Constitution by divesting the Court of Chancery of its equity jurisdiction, and that the retroactive provision did not violate the Delaware Constitution’s due-process protection in the circumstances presented.
The opinion is important, but its scope is limited. The Supreme Court answered constitutional questions; it did not decide the underlying fiduciary-duty claim on the merits, determine that the challenged asset transaction was fair, or find that the defendants had satisfied a §144 safe harbor. Read the opinion for the precise questions certified and the reasoning supporting each answer.
How to read older cases after SB 21
Older decisions remain foundational for understanding fiduciary duties, control, standards of review, process and equitable remedies. But a decision interpreting the pre-amendment common law or former statutory text does not automatically answer a question governed by amended §144 or §220. A careful analysis asks: (1) what version of the statute governed; (2) what kind of transaction or demand is involved; (3) whether the statutory definitions are met; (4) whether the statutory process and conditions were satisfied; and (5) whether a transition exception applies.
The case explorer flags decisions that predate SB 21 or interpret former §220. Particularly relevant examples include MFW in the case explorer; Match in the case explorer; KT4 Partners in the case explorer; AmerisourceBergen in the case explorer; these should be read alongside the current statute and subsequent decisions.
