Professor Ann Lipton at Tulane University Law School has noted a slew of forthcoming papers concerning the internal affairs doctrine in light of Vice Chancellor Laster's holding in Sciabacucchi v. Salzberg, 2018 Del. Ch. LEXIS 578, and California's enactment of a board gender quota.  She notes that Sciabacucchi is currently on appeal to the Delaware Supreme Court, with opening briefs due last week. 

Although the internal affairs doctrine may be the unofficial state religion of Delaware, it is being challenged by its own indeterminacy (what is and isn't an "internal affair") and other states' unwillingness to yield the field of corporate governance to Delaware.  As the Court of Appeal observed more than a quarter century ago in Wilson v. Louisiana-Pacific Resources, Inc., 138 Cal. App. 3d 216 (1982):

"[The internal affairs doctrine] has never been followed blindly in California."
