2.1 Enactment trail (primary sources only)
SB 21 was introduced as a Senate bill on February 17, 2025, substituted in lieu by Senate Substitute 1 on March 12, 2025, and signed by Governor Matt Meyer on March 25, 2025 — the enacted Substitute 1 amends 8 Del. C. § 144 and § 220.4 Both bill records remain available: the original SB 21 (141857) is preserved for provenance, while the enrolled Senate Substitute 1 (141930) is the operative text.5 The act required a two-thirds supermajority of each house under Del. Const. art. IX, § 1 because it amends the General Corporation Law; the Senate passed Substitute 1 unanimously, and the House cleared it 32-7.6
2.2 § 144(e)(2) — the three-prong controller definition
Before SB 21, “controlling stockholder” under Delaware law was a Court of Chancery doctrine, articulated case by case. SB 21 wrote the answer into the statute. Under 8 Del. C. § 144(e)(2), a person is a controlling stockholder if any one of three conditions holds: (i) they own or control a majority in voting power of the outstanding stock entitled to vote in the election of directors; (ii) they hold the contractual or other right to cause the election of nominees constituting a majority of the board; or (iii) they own at least one-third in voting power and exercise managerial authority functionally equivalent to (i) or (ii). The third prong is the operative one for founder-led, dual-class issuers.7 If the statutory conditions are satisfied, § 144(b) or § 144(c) precludes equitable relief or damages for the covered fiduciary-duty claim. The statute does not eliminate all equitable review: § 144(a)(6) preserves specified claims, including challenges to authorization or compliance, injunctive review of defensive devices, and aiding-and-abetting claims.8
2.3 The controller-conflict safe harbor
§ 144(b)–(d) divides controller transactions into two tracks. For an ordinary controller transaction (not a going-private deal), § 144(b) provides three independent routes: committee approval by two or more disinterested directors (§ 144(b)(1)); approval or ratification by an informed, uncoerced majority of votes cast by disinterested stockholders (§ 144(b)(2)); or fairness of the transaction to the corporation and its stockholders (§ 144(b)(3)) — statutory safe-harbor protection applies on any of the three. For a going-private transaction, § 144(c)(1) makes the test conjunctive: both the committee approval and the disinterested-stockholder approval are required — while § 144(c)(2) preserves an independent fairness route. The statute requires the committee to consist of two or more directors each determined disinterested by the board; it imposes no independent-adviser requirement.9 Figure 3 below renders the decision tree.
2.4 Retroactivity and the February 17, 2025 cutoff
SB 21 applies to acts taken or transactions entered into before, on, or after its enactment date, except that it does not apply to (i) civil actions commenced in a court of competent jurisdiction before February 17, 2025, or (ii) books-and-records demands made on or before that same date (with a one-year filing window for certain fiduciary-duty claims accrued before the cutoff).10 The February 17, 2025 cutoff is the bill’s introduction date, not the signing date — the legislature locked retroactivity at announcement to prevent docket-loading. The Rutledge court relied on this carve-out as the constitutional gate for SB 21’s retroactivity (§ 2.6).
2.5 § 220 books-and-records — the narrowing
Amended 8 Del. C. § 220 limits “books and records” to enumerated categories (charter, bylaws, board and committee minutes and resolutions of actions taken, written stockholder communications within the past three years, director and officer independence questionnaires, materials given to the board in connection with action taken, the stock ledger). The amended statute imposes statutory demand requirements: good faith, proper purpose, reasonable particularity, and a specific relation between the requested records and the purpose. Additional specific records require a compelling-need showing and clear-and-convincing evidence that the records are necessary and essential to the proper purpose — the codified standard operates in addition to the common-law “credible basis” pleading threshold articulated in Seinfeld v. Verizon Communications, Inc., 909 A.2d 117 (Del. 2006).11 The amended statute also permits the corporation to impose reasonable confidentiality conditions. The practical effect is that broad non-enumerated electronic-record requests are constrained by the enumerated categories and the compelling-need showing; the expansive reading in KT4 Partners LLC v. Palantir Technologies Inc., 203 A.3d 738 (Del. 2019)12 is now bounded by the enumerated categories.
2.6 Rutledge v. Clearway: certified-question rejection of constitutional challenges to SB 21
The Court of Chancery certified two questions to the Delaware Supreme Court: (i) whether SB 21 violated Article IV, § 10 by “freezing” the equitable jurisdiction of the Court of Chancery, and (ii) whether the retroactivity provision violated Article I, § 9 of the Delaware Constitution by extinguishing vested rights or accrued causes of action. The Delaware Supreme Court heard oral argument on November 5, 2025. In Rutledge v. Clearway Energy Group LLC, No. 248, 2025 (Del. Feb. 27, 2026) (Traynor, J., for a unanimous Court sitting en banc; Seitz, C.J., Valihura, LeGrow, and Griffiths, JJ., joining), the Court answered both questions in the negative.13 Article IV, § 10 vests equitable jurisdiction in Chancery but does not freeze the substantive scope of equity; the General Assembly retains the power to define the scope of fiduciary duties and the procedural pathways for testing them. The retroactivity provisions do not impair vested rights because (a) the February 17, 2025 cutoff preserves accrued claims, and (b) the General Assembly retains authority to enact substantive law affecting fiduciary doctrine, subject to the Article I, § 9 vested-rights carve-outs preserved in the statutory transition provisions.14 Governor Meyer issued a same-day statement.15
Doctrinal framing — not a Tornetta override
SB 21 should not be described as statutorily superseding Tornetta. It changes the review framework within which controller-conflict claims are evaluated; it does not extinguish the claims. The Court of Chancery retains jurisdiction over breach-of-fiduciary-duty actions; the safe harbors operate as legislative defenses that, when satisfied on their statutory terms, foreclose equitable relief or damages. The common law continues to govern controller-conflict claims outside the § 144 safe-harbor procedures. Rutledge itself describes the architecture in those terms.
2.7 In re Tesla, Inc. Derivative Litigation — the reversal
In In re Tesla, Inc. Derivative Litigation, Nos. 534, 2024; 10, 2025; 11, 2025; & 12, 2025, 2025 WL 3689114 (Del. Dec. 19, 2025) (per curiam, en banc), the Delaware Supreme Court reversed the Court of Chancery’s order rescinding Elon Musk’s 2018 Tesla compensation plan and reversed the $345 million fee award.16 The disposition was affirmed in part, reversed in part. The Court took what it described as the narrower of three available paths: it held that rescission of the 2018 plan was an improper remedy, and otherwise avoided whether the 2018 plan was entirely fair to Tesla or had been effectively ratified by stockholders after the June 13, 2024 stockholder vote. The Court awarded plaintiff $1 in nominal damages and displaced the Court of Chancery’s $345 million fee award with a quantum-meruit fee set at four times counsel’s lodestar, plus costs and post-judgment interest. The Court stated no dollar amount and directed any fee disputes to the Court of Chancery; the widely reported $54.5 million was the cap defendants proposed — four times their own computation of the lodestar — not a court-fixed award.17 The headline is the displacement of the $345M award by a lodestar-times-four quantum-meruit standard — on defendants’ own lodestar computation, an approximately 84% reduction.
