DExit Averted?: Rutledge v. Clearway Energy Group Locks SB 21 Into Place

The Delaware Supreme Court’s February 2026 decision in Rutledge v. Clearway Energy Group, LLC, No. 248, 2025, 2026 WL 548504 (Del. Feb. 27, 2026) cements to the Delaware General Corporate Law the contentious amendments brought on by Senate Bill 21 (“SB 21”), which sets a new baseline standard of review for conflicted‑transaction litigation and meaningfully rebalances power away from stockholder‑plaintiffs and toward boards, officers, and controllers. The specific changes introduced by SB 21were discussed in a previous client alert.

The takeaway for shareholders of Delaware‑domiciled corporations is that there will be fewer viable fiduciary‑duty claims, a greater premium on ex ante process, and a heightened focus on independence and deal structure rather than open‑ended, post-hoc fairness review.

The constitutional challenges in Rutledge turned on two issues:

• whether SB 21 divested the Court of Chancery “of equitable jurisdiction below the constitutional minimum established by” the Delaware Constitution; and
• whether the retroactive application of SB 21 to causes of action that vested prior to its enactment violated due process.[1]

The Court rejected both arguments. On jurisdiction, the justices distinguished stripping the Court of Chancery of its constitutionally vested authority over fiduciary‑duty actions from that court’s ability to prescribe when those actions can yield particular remedies. The Court held that SB 21 does the latter: breach‑of‑fiduciary‑duty claims still lie in Chancery, but when a transaction satisfies the statutory safe harbor, the court is simply without jurisdiction to award damages or equitable relief. Such an outcome is the result of “a legitimate exercise of the General Assembly’s authority to enact substantive law,” rather than a jurisdictional carve‑out.[2]

Turning to retroactivity, the Court found the application of SB 21 to pre‑enactment conduct, subject to an exception for “any action or proceeding . . . that is completed or pending . . . on or before February 17, 2025,” did not violate due process because it adjusts standards of review and available remedies without eliminating all causes of action.[3] For stockholders, that means deals signed before March 2025 may still be adjudged under SB 21 if the temporal criteria are met, thus cutting off some pre‑amendment claims that might have appeared stronger.

The practical consequence of SB 21 is unchanged post-Rutledge: shareholders will continue facing diminished litigation leverage. If a board constitutes a genuinely disinterested, independent committee that acts in good faith and without gross negligence, or obtains an uncoerced, fully informed majority‑of‑the‑minority vote, many fiduciary‑duty claims will remain dead in the water. Minority shareholders can therefore expect fewer cases that can plausibly proceed on a pure “unfair price or process” theory once formal cleansing mechanisms are in place. Their litigation burden moves toward showing that directors are not, in fact, independent, and that minority votes were coerced or compromised by incomplete disclosures.

Sophisticated investors might combat this reconfiguration through strategic adjustments on both governance and litigation fronts. Institutional and activist shareholders could push to memorialize protections exceeding statutory minimums. In the courtroom, plaintiffs’ counsel will likely invest more in fact‑intensive development around independence, social and business ties, vote integrity, and in arguments that specific deals are beyond SB 21’s defined transaction types or that safe‑harbor conditions were not met in good faith or without gross negligence. The statute’s bright lines invite edge‑case litigation over who qualifies as a controlling stockholder, a disinterested director, or a disinterested stockholder.

From a policy level, SB 21 and the Delaware Supreme Court’s endorsement are aimed at shoring up Delaware’s corporate law franchise in the face of “DExit.” For issuers and controllers, this regime change promises greater predictability—a clearer procedural roadmap that cabins fiduciary exposure and reduced volatility associated with post‑transaction judicial scrutiny. For shareholders, predictability can signal whether and when litigation is likely to fail, thereby incentivizing a shift toward governance design, proxy contests, and deal‑process interventions, rather than reliance on (and threats of) post-hoc entire‑fairness lawsuits.
