Can ChatGPT Do Our Jobs Better Than Us? Not Yet.

Artificial intelligence and its impact on the practice of law is in the news again. Readers likely have heard about the attorneys that used ChatGPT, an artificial chatbot that synthesizes high volumes of data, to draft a legal brief that they submitted in a civil action in the U.S. District Court for the Southern District of New York. Unfortunately for these practitioners, ChatGPT cited multiple cases that did not exist, and the attorneys recently endured a sanctions hearing before the presiding district judge.


Corporate Officers’ Role in Corporate Governance: What Officers Need to Know

The recent Delaware Court of Chancery decision, In re McDonald’s Corporate Stockholder Derivative Litigation is a reminder of corporate officer duties and the vital role that corporate officers play in corporate governance, at both publicly and privately held corporations. These duties stem from officers’ status as both agents and fiduciaries. For boards of directors and other officers to perform their roles effectively, it is critical for officers to understand an satisfy their duties. Failure to do so may deprive boards of directors of information they need to monitor operations, mitigate risks and establish strategy and can expose officers to personal liability.


Court of Chancery Dismisses Director Oversight Claims Related to Mission Critical Risk

In a March 1, 2023 opinion (In re McDonald’s Corp. Stockholder Derivative Litig., C.A. No. 2021-0324-JTL), the Delaware Court of Chancery dismissed duty of oversight claims against director defendants and provided helpful guidance on “mission critical” risks, the “gross negligence” standard under the business judgment rule, and redactions in productions of books and records under DGCL Section 220, including the potential that a motion to dismiss relying on overly redacted documents from a 220 production could be converted to a motion for summary judgment by the court. The court also entered an order on the same day, granting the defendants’ Rule 23.1 motion and dismissing the action in its entirety, including claims against the company’s former Global Chief People Officer. The court had previously denied a motion to dismiss those claims under Rule 12(b)(6) on January 25, 2023, as discussed further here, underscoring the important role of Rule 23.1 in derivative cases.


Where Caremark Meets Park: A New Era of Regulatory Compliance and Criminal Liability

In a recent post on, Paul Kalb (a co-founder of Sidley’s Global Life Science practice) and Coleen Klasmeier (a former partner who co-led Sidley’s Food, Drug and Medical Device practice) discuss how the intersection of the Caremark and Park doctrines impact life science companies, particularly when it comes to regulatory compliance and the liability of company officials.


Delaware Court of Chancery Addresses Officer Oversight Obligations

In a January 25, 2023 opinion (In re McDonald’s Corp. Stockholder Derivative Litig., C.A. No. 2021-0324-JTL), the Delaware Court of Chancery clarified that corporate officers’ fiduciary duties encompass a duty of oversight. As with directors, the duty of oversight requires that officers: (1) make a good faith effort to put in place reasonable information systems to generate the information necessary to address risks and report upward to higher level officers or the board; and (2) not consciously ignore red flags indicating that the company may suffer harm. The Court of Chancery also clarified that officers will not be held liable for violations of the duty of oversight unless they are shown to have acted in bad faith, as opposed to mere gross negligence.


Trial Judgment “Knocks The Stuffing” Out Of Putative Derivative Suit Relating To Opioid Distribution

Last month, Delaware’s Court of Chancery issued two significant decisions in a stockholder litigation involving AmerisourceBergen Corporation (the “Company”) and its wholesale distribution of prescription opioids in the United States.  Together, the decisions provide companies and their directors and officers with further guidance regarding the viability of so-called Caremark claims alleging breaches of fiduciary duties.


Board’s Good-Faith Oversight of “Mission Critical” Risks Insulates Directors from “Caremark” Claim

In 1996, the Delaware Court of Chancery issued its seminal decision in In re Caremark International Inc. Derivative Litigation, which establishes the framework for director oversight liability under Delaware law. Over time, Delaware courts frequently observed that this type of claim was “possibly the most difficult theory in corporation law upon which a plaintiff might hope to win a judgment,” and these claims rarely advanced beyond the motion-to-dismiss stage. However, in a three-year span beginning in 2019, Delaware courts denied motions to dismiss Caremark claims in five cases, leading some to question whether the Caremark standard has been relaxed. A recent Court of Chancery decision issued earlier this summer provides an important counterpoint to this recent commentary, while underscoring that boards must exercise rigorous oversight over “mission critical” risks.


Best Practices for Minute-Taking: Three Lessons from Recent Caremark Decisions

As has been frequently noted on this page, the Delaware Supreme Court’s landmark 2019 decision, Marchand v. Barnhill, marked the beginning of a series of cases in which Delaware courts refused to dismiss shareholder derivative actions alleging oversight breaches—so-called Caremark claims, which are often quoted as “possibly the most difficult theory in corporat[e] law” on which to bring a successful lawsuit. Typically following a books and records demand, these cases shine a spotlight not only on the oversight that boards perform, but also on the manner in which that oversight is documented in a company’s formal records. This post reviews, from a corporate record-keeping perspective, themes drawn from a selection of recent cases in which Delaware courts permitted cases to proceed on Caremark theories and implications for best practices in light of these themes.

Caremark’s Comeback Includes Potential Director Liability in Connection With Data Breaches

A Caremark­-based claim against a board of directors alleging a failure to monitor corporate operations has been said to be “the most difficult theory in corporation law upon which a plaintiff might hope to win a judgment,” or at least to withstand a motion to dismiss.  Yet, Caremark has taken on renewed importance — as noted by this blog — following recent high-profile successes on duty-to-oversee claims, most notably in Marchand v. Barnhill in 2019 and In re Boeing in September 2021, and recent shareholder lawsuits alleging that data breach- and cybersecurity-related failures would have been preventable were it not for oversight failures by corporate officers and directors, are being plead asserting Caremark claims.

Increased Scrutiny Has Boards of Directors in the Hot Seat

Life is getting harder for boards of directors of public companies. Increased scrutiny of companies — particularly in heavily regulated industries — has led to greater risk of criminal and civil liability. And recent Delaware cases have ratcheted up the pressure, allowing lawsuits to proceed against boards for failure of oversight. What should directors know about their oversight responsibilities? And what can boards do to mitigate their risk? Our latest episode of The Sidley Podcast grapples with those questions and many others. Join host and Sidley partner, Sam Gandhi, as he speaks with two of the firm’s thought leaders on the subject — Holly Gregory and Dr. Paul Kalb.
