Professor Mohsen Manesh cites two developments in 2018 as a possible turning point for the internal affairs doctrine: California's enactment of a board gender quota law and Vice Chancellor Laster's ruling in Sciabacucchi v. Salzberg, C.A. 2017-0931 JTL (Del. Ch. Dec. 19, 2018).  He finds:

"Although seemingly unrelated, both events share at their core a challenge to the internal affairs doctrine—a doctrine that is at the foundation of the state-based system of corporate law in the United States."

The Contested Edges of Internal Affairs (forthcoming).  Professor Manesh concludes with this less than sanguinary prognostication of the future of Delaware's hegemony:

"But recent events suggest that this unrivaled power may be unraveling at the edges. The boundaries of the internal affairs doctrine are now the subject of dispute, and additional challenges are likely to surface.  As other states seek to contest the scope of the internal affairs doctrine, restricting and expanding its reach, Delaware confronts a new threat to its lucrative regulatory domain, and corporate America faces a fundamentally altered regulatory landscape."
