The Billionaire’s Bill Holds: Delaware’s SB 21 Victory Cements the State’s Corporate Defense Strategy

Delaware just sent a clear message to corporate America: the First State is open for business, and it’s not apologizing for it. On February 27, 2026, the Delaware Supreme Court upheld Senate Bill 21—the sweeping 2025 corporate law overhaul that makes it harder to challenge controller transactions and limits stockholder inspection rights. The decision marks a decisive win for Delaware’s business establishment and a significant setback for the plaintiffs’ bar that has long dominated corporate litigation in the state.

The Statute That Sparked a Backlash

SB 21 emerged from a perfect storm of corporate anxiety. After a series of Chancery decisions that scrutinized controller transactions with increasing intensity—including the Match Group and Mindbody rulings—Delaware faced genuine competition from Texas, Nevada, and other states pitching themselves as more management-friendly alternatives. The state’s response was swift and comprehensive: raise the pleading bar for entire fairness review, provide safe harbors for conflicted transactions, and narrow the scope of books-and-records demands under 8 Del. C. § 220.

Critics dubbed it the “billionaire’s bill” for good reason. The statute effectively creates a presumption of business judgment protection for controller transactions that receive approval from a properly empowered special committee or a majority-of-the-minority vote—a framework that mirrors but expands the MFW doctrine. It also restricts § 220 demands to formal board materials, cutting off access to emails, texts, and other informal communications that have proven devastating in recent cases.

The Supreme Court’s Stamp of Approval

The Delaware Supreme Court’s decision to uphold SB 21 is remarkable not for its outcome—few expected the court to strike down the legislature’s handiwork—but for its timing and tone. By validating the statute less than a year after enactment, the court has removed any lingering uncertainty about Delaware’s direction. The message to corporate planners is unmistakable: Delaware remains the gold standard, and it will defend that position aggressively.

“The General Assembly has spoken clearly on matters of corporate governance, and this Court will not substitute its judgment for that of the elected branches on questions of policy properly committed to them.”

This deference is significant. The court could have parsed the statute’s safe harbor provisions narrowly or imposed procedural requirements that would have blunted their impact. Instead, it embraced the legislative framework wholesale, signaling that Delaware’s corporate judiciary and legislature are aligned in their commitment to maintaining the state’s competitive edge.

What This Means for Practice

For deal lawyers, SB 21’s survival creates immediate planning opportunities. The statute’s safe harbors for controller transactions are now firmly established, making Delaware an even more attractive venue for companies with significant insider ownership. Expect to see more controlling stockholders incorporating in Delaware rather than fleeing to Texas or Nevada, reversing a trend that had begun to gain momentum.

The § 220 limitations are equally consequential. Plaintiffs’ firms have long used books-and-records demands as discovery tools, fishing for informal communications that could support breach-of-fiduciary-duty claims. With access now restricted to formal board materials, the economics of stockholder litigation shift dramatically. Cases that once seemed viable after a § 220 demand may now be dead on arrival, particularly in the context of controller transactions where the safe harbor provisions apply.

For litigators, the decision forces a strategic recalibration. The traditional playbook—file a § 220 demand, obtain damaging emails, and leverage those materials into a settlement—no longer works in many cases. Plaintiffs will need to develop alternative theories or focus on jurisdictions with more favorable procedural rules. This could accelerate the migration of corporate litigation to federal courts, where state-law fiduciary duties play a smaller role.

The Broader Implications

Delaware’s successful defense of SB 21 is part of a larger story about the state’s willingness to adapt to competitive pressures. The same dynamic played out in the Moelis litigation, where the legislature quickly amended the DGCL to protect stockholder agreements after Chancery invalidated them. The pattern is clear: when Delaware’s corporate franchise is threatened, the state responds with legislative and judicial coordination that few competitors can match.

This responsiveness has costs. The “billionaire’s bill” moniker reflects genuine concern that Delaware is tilting the playing field too far toward insiders at the expense of public stockholders. If other states follow Delaware’s lead—and they will—the result could be a race to the bottom in corporate governance standards, with predictable consequences for investor protection.

For now, though, Delaware has won the battle. The Supreme Court’s decision ensures that SB 21 will shape corporate litigation for years to come, and the state’s dominance in corporate law remains unchallenged. The plaintiffs’ bar will adapt, as it always does, but the rules of the game have changed fundamentally. Corporate defendants have a new shield, and they’re not afraid to use it.
