LASTER, V.C.

A brother, his three sisters, and their adult children share ownership of a storied and successful grocery store chain in New England. The brother ran the business profitably as CEO for nearly two decades, but he stubbornly resisted board oversight and excluded his sisters and their families from the business.

The sisters sought change. Over approximately five years, the sisters gradually replaced the CEO’s longtime allies on the board with independent, outside directors. When the sisters introduced the first independent director, they thought he could work cooperatively with the CEO and his fellow directors to improve corporate governance and transparency. Two years later, nothing had changed, so the sisters introduced a second independent, outside director, believing that two directors might succeed where one had failed. The CEO opposed both directors, regarded them as his sisters’ agents, and resisted their efforts. After the CEO responded to a meeting with the two directors by sending them hostile letters attacking them and copying all of the stockholders, the sisters added a third independent, outside director.

The three outside directors constituted a majority of the five-member board.

Having witnessed the CEO’s imperious style firsthand, they anticipated ongoing confrontations over long-term strategy and succession. For the company, it would be “déjà vu all over again”1 and reprise a conflict from a decade earlier between the siblings and their cousins. In that prior incident, the CEO’s obstinacy eventually

caused one of his supporters to switch sides, and the cousins used their newfound stockholder-level majority to establish a board majority and remove the CEO. He in turn fought back by leading a weeks-long employee walkout and customer boycott. Although his brinksmanship nearly destroyed the company, it ultimately forced a resolution in which the siblings bought out their cousins. Not only that, but the boycott and walkout ended up helping the company through increased brand loyalty.

The three directors desperately wanted to avoid a similar confrontation. To demonstrate to the CEO that they were serious about change, they drew up a list of straightforward governance issues and delivered it to the CEO during an executive session. The CEO did not respond constructively. Over the ensuing months, he made a few token gestures while aggressively digging in on the principal issues. When the three directors made specific requests, he took a hardline, passive-aggressive approach. The boardroom environment became toxic.

In spring 2025, the three directors heard rumors that the CEO’s principal lieutenants were preparing for another employee walkout and customer boycott. They rationally concluded that the CEO was getting ready for a fight. Believing in good faith that another walkout and boycott would be disastrous for the company, they took action. They formed an executive committee consisting of themselves so that the CEO’s remaining director ally would not be party to their deliberations. Then they suspended the CEO and key members of his team pending a law firm investigation.

The CEO escalated. Through intermediaries, he launched a social media campaign ridiculing the three directors and his sisters. That effort included a website

that posted their personal contact information, resulting in death threats. He also conducted a public relations campaign featuring statements to the press criticizing the directors and his sisters. When the Boston Globe ran an op-ed calling for a customer boycott, the campaign’s social media account promoted it. The CEO also continued communicating with his lieutenants, who trespassed on company property to drum up support for the CEO. Meanwhile, the law firm investigation did not exonerate him.

The three directors attempted mediation. When that failed, the three directors terminated the CEO and filed this action to confirm the validity of their actions. The CEO asserted affirmative defenses and a counterclaim that contended the three directors breached their fiduciary duties when first suspending and later terminating him.

By the time of trial, no one disputed the legal validity of the directors’ actions.

The only disputes involved whether they acted equitably. On those issues, the CEO bore the burden of proof.

The CEO sought to prove that the directors breached their duty of loyalty by acting in bad faith to benefit his sisters and their families. He failed to carry his burden.

The record does not support a finding that the directors were beholden to the sisters. To be sure, they consulted with the sisters, took their concerns into account, and considered the stockholder-level disputes between the sisters and the CEO, but directors can legitimately do that. Here, the three directors rationally concluded—

one could say reasonably or fairly concluded—that the CEO’s longstanding resistance to board oversight, imperious manner, and refusal to compromise with his sisters threatened the company. The CEO proved that he was a good operator and that the directors did not suspend or terminate him because of problems with the business. That, however, is not the only dimension of a CEO’s job. Nor is it all that directors can consider.

The directors acted in good faith when initially suspending and later terminating the CEO. The business judgment rule protects their decisions. Judgment will be entered in their favor and against the CEO.
