Business litigation

Venue

District of Massachusetts

Outcome

High-stakes shareholder and fiduciary dispute

Why this matter was high-stakes

Demoulas/Market Basket litigation
Shareholder fiduciary dispute
Published federal decision
Corporate governance at scale

The dispute

The Demoulas family litigation over control of the Market Basket supermarket chain is among the most bitter shareholder disputes in Massachusetts history. Kettenbach v. Demoulas arose in that context—addressing fiduciary duties, shareholder rights, and corporate governance in a closely held enterprise.

Legal issues

The case required analysis of breach-of-fiduciary-duty claims, shareholder oppression, and the remedies available when corporate insiders prioritize personal interests over shareholder value. Federal jurisdiction added complexity through diversity and supplemental jurisdiction questions.

Published opinion

The District Court issued a published decision at 901 F. Supp. 486—part of the extensive reported litigation surrounding one of New England's largest private companies.

Firm experience

Business litigation at this scale demands trial-ready staffing on financial records, corporate structure, and fiduciary standards—the same discipline the firm applies to criminal and civil-rights matters.
