The Delaware Supreme Court’s unanimous decision in Rutledge v. Clearway Energy puts the state’s sweeping 2025 corporate governance reforms on solid ground and reshapes how practitioners should think about controller transactions, fiduciary duty litigation, and shareholder rights going forward.
On February 27, 2026, the Delaware Supreme Court issued a unanimous ruling upholding Senate Bill 21 (SB 21), arguably the most significant rewrite of the Delaware General Corporation Law (DGCL) in a generation. The decision, written by Justice Gary F. Traynor in Rutledge v. Clearway Energy Group LLC, ends months of legal uncertainty about whether the Legislature overstepped by expanding liability shields and narrowing shareholder inspection rights, and does so with a resounding answer: it did not.
For startup founders, venture investors, and the transactional lawyers who work with them, this ruling is genuinely important. Delaware remains the governing law for the overwhelming majority of venture-backed companies, and SB 21 changes, in concrete and practical ways, how controller transactions are structured, how minority shareholders can challenge board decisions, and how much leverage a litigant can extract from a Section 220 books-and-records demand. Let me walk through what happened, why it matters, and what you should be doing about it.
Background: Why SB 21 Existed in the First Place
Delaware’s corporate law dominance is not an accident—it’s the product of a century of deliberate investment in a sophisticated judiciary (the Court of Chancery), an adaptive legislature, and a dense body of case law that gives practitioners something unusual in the law: genuine predictability. More than two-thirds of Fortune 500 companies are incorporated in Delaware, and in the venture and startup ecosystem, it’s close to the default. The franchise fees generated from those incorporations fund more than 20% of the state’s general budget.
That dominance faced real pressure heading into 2025. A series of Court of Chancery decisions, most notably In re Match Group, Inc. Derivative Litigation, 315 A.3d 446 (Del. 2024), imposed increasingly demanding standards on controller transactions. Under the pre-SB 21 regime, a transaction involving a controlling stockholder could only receive deferential business judgment review if it satisfied both prongs of the so-called MFW framework simultaneously: approval by an independent board committee and a majority of disinterested stockholders, conditioned on both approvals from the outset. Miss either requirement and you faced entire fairness review (requiring fair process and fair terms) an expensive, unpredictable, and prolonged litigation standard.
Companies began talking publicly about redomesticating to Texas or Nevada, both of which were aggressively developing business court systems and offering friendlier statutory frameworks. That ‘DExit’ threat was the political catalyst for SB 21, which Governor Matt Meyer signed on March 25, 2025, just weeks after it was introduced. It passed with bipartisan support, and took effect immediately, applying both prospectively and retroactively, with limited exceptions for proceedings already pending as of February 17, 2025.
What SB 21 Actually Does: The Key Changes
The legislation amended two provisions of the DGCL that are fundamental to corporate litigation: Section 144, which governs conflict-of-interest transactions, and Section 220, which gives shareholders the right to inspect corporate books and records.
Section 144: The New Safe Harbor Framework
Before SB 21, Section 144’s safe harbor for interested-director transactions was broadly understood not to extend to controlling stockholder transactions. The Chancery courts had developed a separate framework for those deals, requiring satisfaction of both the independent committee and disinterested stockholder approval requirements under the MFW doctrine.
SB 21 dismantles that dual-requirement framework for non-going-private transactions. Under the new Section 144(b), a transaction involving a controlling stockholder (other than a going-private deal) obtains safe harbor protection if approved by either: (1) a committee of a majority of disinterested directors, or (2) a majority of votes cast by disinterested stockholders. One or the other, not both. For going-private transactions under Section 144(c), both approvals remain required, essentially codifying MFW while eliminating its ab initio precondition requirement.
The law also defines ‘controlling stockholder’ with statutory precision for the first time: a party with majority voting power, or a party with at least one-third of the voting power who also exercises managerial authority over the business. Control groups, collections of stockholders acting together, are similarly defined. Controlling stockholders are expressly shielded from duty-of-care damages in their capacity as controllers, limiting their exposure to breaches of loyalty, bad faith, and improper personal benefit.
Critically, satisfying the safe harbor now precludes both monetary damages and equitable relief. That last point is significant: previously, even a properly cleansed transaction could be unwound by equity. Under SB 21, if you follow the statutory procedures, you’ve effectively foreclosed the full range of judicial remedies, not just money damages.
Section 220: Narrowing Books-and-Records Demands
Section 220 had become one of the plaintiff bar’s most potent tools for pre-litigation discovery. By filing a books-and-records demand, shareholders could obtain internal emails, board communications, and informal working documents that would then be incorporated by reference into derivative complaints, giving plaintiffs a substantial informational advantage before formal litigation even began.
SB 21 limits the scope of ‘books and records’ to formal corporate documents: governing documents, board and committee minutes, board presentations, financial statements, and director and officer independence questionnaires. Emails, texts, and informal communications are now expressly excluded from the definition. Shareholders must describe their demand with ‘reasonable particularity,’ state a proper purpose, and show that the requested records are specifically related to that purpose. Corporations can impose confidentiality restrictions and redact information unrelated to the shareholder’s stated purpose.
The Clearway Energy Case and the Constitutional Challenge
The case that brought the constitutional challenge was Rutledge v. Clearway Energy Group LLC, case no. 248,2025. Stockholder Thomas Drew Rutledge challenged a $117 million asset purchase, a wind energy project in Idaho, contending the transaction was unfair and had not been approved by a majority of the minority stockholders. By the time the case reached Chancery, the court had to grapple with whether the newly enacted SB 21 applied, and Clearway invoked the statute’s safe harbor protections.
Plaintiffs’ counsel Gregory Varallo of Bernstein Litowitz argued before the Supreme Court on November 5, 2025, that SB 21 was unconstitutional because it stripped the Court of Chancery of its equitable jurisdiction without providing an adequate substitute remedy, an argument with deep roots in Delaware constitutional law. The Court of Chancery’s authority to ‘do equity’ is grounded in the Delaware Constitution itself, and the argument was that the General Assembly cannot simply legislate away the court’s core equitable powers.
The Supreme Court rejected this framing. The unanimous opinion held that the question is not whether the legislature can eliminate Chancery’s equitable jurisdiction (it cannot) but whether SB 21 actually does that. The court concluded it does not. The statute merely establishes a safe harbor; it does not eliminate the court’s ability to hear cases or fashion remedies where the safe harbor is not satisfied. The Legislature, the court found, acted within its authority to define the statutory contours of conflict-of-interest liability.
What This Means for Founders, Investors, and Practitioners
For founders and boards navigating investor relationships:
If your company has a controlling stockholder, which, in the venture context, often means a lead investor with board control rights or a founder with supervoting shares, the new framework provides a much clearer path to structuring related-party transactions. The old regime created a structuring dilemma: you either jumped through the dual MFW hoops from day one or faced the prospect of entire fairness litigation. The new single-cleansing-mechanism structure for non-going-private transactions simplifies that calculus significantly.
That said, ‘simpler’ doesn’t mean ‘effortless.’ The independent committee members must be genuinely disinterested and independent under the statutory definitions. The documentation of that independence (questionnaires, deliberation records, board minutes) has become more important than ever, since it’s the evidentiary basis for claiming the safe harbor. If the process looks clean but the paperwork doesn’t support it, you’re exposed.
For investors conducting M&A and venture due diligence:
The Section 220 changes have a direct impact on how disputes get litigated (and therefore on litigation risk assessment in M&A and investment contexts). Historically, one of the first moves in any corporate governance dispute was a books-and-records demand that yielded informal communications that could make an otherwise defensible transaction look terrible in the press and in court. That tool has been blunted. Emails and texts are out; formal board materials are in. This likely shifts some of the informational advantage back toward management in early-stage litigation disputes.
What this also means is that maintaining high-quality board governance documentation (real minutes, real deliberation, actual independence questionnaires) is now a more critical risk management practice than it was before SB 21. When those formal records are the primary discovery battleground, they need to be able to stand on their own.
For companies considering Delaware vs. other jurisdictions:
The ruling shores up Delaware’s position as the dominant corporate domicile, at least for now. Governor Meyer was quick to frame the decision as confirmation that ‘Delaware is the gold standard locale for global companies to do business.’ That framing, while partially self-serving, reflects something real: the combination of predictable statutory law, the Chancery Court’s sophistication, and the deep body of precedent remains genuinely unmatched. Nevada and Texas may offer more permissive liability standards, but they lack the judicial infrastructure and precedential depth that sophisticated transactional lawyers actually rely on.
That said, I think the tension doesn’t fully resolve here. Professor Charles Elson of the University of Delaware, a respected voice in corporate governance, put it plainly in responding to the ruling: by upholding SB 21, the court has effectively validated the principle that the Legislature can override Supreme Court decisions through statutory change. Whether that precedent will be used responsibly, or will invite further erosion of minority shareholder protections in future legislative sessions, remains an open question.
The Retroactivity Issue: A Remaining Concern
One aspect of the decision that deserves attention is the retroactivity provision. SB 21 applies to transactions occurring before March 25, 2025, not just to future deals, with an exception for proceedings pending or books-and-records demands made before February 17, 2025. Varallo argued during oral argument that retroactive application was constitutionally infirm. The Supreme Court did not fully resolve this argument, focusing its constitutional analysis on the jurisdictional question.
For parties with legacy transactions that might have been subject to litigation under the pre-SB 21 standard, this is a critical point. If those transactions were completed before March 2025 but no proceeding was filed before February 17, 2025, SB 21 likely applies and the new safe harbor framework governs. That could rescue transactions that would have faced entire fairness scrutiny under the old rules. Practitioners should audit their client portfolios with this in mind.
Practical Checklist: Steps to Take Now
Given the ruling’s finality, here are the concrete steps boards, founders, and investors in Delaware corporations should consider:
First, revisit your director independence documentation. The new Section 144 safe harbors turn on whether committee members are ‘disinterested’ under the statute’s definitions. Board questionnaires and independence determinations should be updated to track the new statutory language, not just legacy Chancery precedents.
Second, build Section 220 compliance into your governance infrastructure. Corporations should now be maintaining formal board and committee minutes as a matter of routine, because those records (not informal communications) are what shareholder plaintiffs will get in discovery. Sloppy minutes or gaps in the formal record now carry more litigation risk.
Third, if your company is a party to a pending or anticipated related-party transaction with a controlling stockholder, work with counsel to structure it explicitly under the new Section 144 framework. The choice between committee approval and stockholder ratification has strategic implications that depend on your specific shareholder composition and governance structure.
Fourth, revisit legacy transactions. If you have completed deals that were structured before SB 21 but no litigation was filed before February 17, 2025, there’s a reasonable argument the new framework applies. That’s worth a conversation with Delaware counsel.
Looking Ahead
The Delaware Supreme Court’s ruling in Clearway Energy provides a decisive answer to the immediate constitutional question. SB 21 stands. Delaware’s corporate governance framework has been substantially rewritten, and the rewrite has now survived judicial scrutiny.
What this ruling does not resolve is the longer-term trajectory. Delaware’s legislative response to Chancery decisions created a precedent for a more interventionist legislature, one willing to move quickly to override judicial developments it dislikes. If that pattern continues, the predictability that made Delaware valuable in the first place could gradually erode. The best safeguard against that scenario is continued investment in the Chancery Court’s quality and independence, and a transactional bar that continues to develop thoughtful case law around the new statutory framework.
