Delaware’s courts traditionally have said that breach of the duty of oversight claims (sometimes referred to as Caremark claims) are “possibly the most difficult theory in corporation law upon which a plaintiff might hope to win a judgment.” However, in series of cases following the Delaware Supreme Court’s 2019 decision in Marchand v. Barnhill, Delaware courts have sustained a number of breach of the duty of oversight claims. More recently, Vice Chancellor Laster, in a pair of decisions in the McDonald’s case, elaborated significantly on the reach of duty of oversight. Among other things, Laster made it clear that the duty extends to corporate officers as well as to directors. Some commentators (including me) were concerned that Laster’s elaborations could lead to further lawsuits alleging breach of the duty of oversight.
Now, in what is the first high-profile post-McDonald’s Caremark claim of which I am aware, a group of four institutional investors has brought a breach of the duty of oversight claim against certain directors and officers of Meta, alleging that the executives failed to take sufficient action with respect to allegations that the company’s social media sites were being used for human trafficking. The new complaint appears to have been shaped to reflect many of the implications arising from Laster’s decisions in the McDonald’s case. A copy of the redacted public version of the plaintiffs’ March 20, 2023, complaint in the Meta case can be found here.

In the latest example of claimants seeking to assert the newly revitalized type of claim for breach of the duty of oversight against corporate boards, plaintiff shareholders have filed a derivative lawsuit in Delaware Chancery Court against certain past and current directors of technology company SolarWinds, based on the massive cybersecurity incident involving the company’s software and systems discovered in December 2020.
