Influence Without Control: Private Funds, Shareholder Engagement, and the New Law of Control

Delaware Senate Bill 21 (“SB 21”) has been widely framed as a politically motivated response to corporate flight, billionaire backlash, and perceived judicial overreach in controlling-shareholder doctrine. This Article argues that those accounts miss one of SB 21’s most consequential legal developments: its redefinition of the boundary between shareholder influence and corporate control. By replacing Delaware’s open-ended “actual control” doctrine with a statutory framework anchored in ownership thresholds and board-level authority, SB 21 transforms control from an ex post judicial determination into an ex-ante design choice.
Through doctrinal analysis and original qualitative interviews with leading corporate advisors, this Article shows how SB 21 stabilizes transaction planning while formally insulating traditional forms of minority shareholder engagement—persuasion, voting, proxy contests, and limited board representation—from fiduciary status below a one-third ownership threshold. The statute’s effects extend well beyond founder-led firms, reshaping the governance strategies of private equity sponsors, venture capital funds, and activist investors. Finally, this Article underscores how SB 21 simultaneously blesses increasingly aggressive minority-stake engagement while leaving unresolved—and in some cases exacerbating—new forms of contractual and economic control. Ultimately, SB 21 does not merely respond to recent cases; it recasts the law of corporate control itself, with lasting consequences for shareholder activism, private ordering, and the future of fiduciary accountability in Delaware corporate law.
