Represented minority shareholders of a national fragrance retailer in a derivative litigation in the Delaware Court of Chancery. Successfully objected to an inadequate settlement agreement proposed by the Special Litigation Committee, and litigated a more favorable resolution causing the ultimate sale of the company to a third party. This resulted in our clients receiving $40 million for their shares and the Court of Chancery approving a significant attorneys’ fees award for our representation.
Represented an international energy company in a dispute over control of a multibillion-dollar company in the Delaware Court of Chancery, ultimately defeating minority stakeholders’ attempt to compel a sale of the company.
Trial counsel to a Fortune 500 biotechnology company in an arbitration brought against it by its collaborator, a Fortune 100 pharmaceutical company, seeking to gain control over the right to commercialize a novel, billion-dollar multiple sclerosis drug. Following a multi-week hearing, the arbitrator ruled in favor of the client on all claims.
Successfully represented Vertex Pharmaceuticals, Inc. in a securities class action complaint filed against Vertex and the company’s senior executives by Local No. 8 IBEW Retirement Plan and Trust. We successfully rebuffed plaintiffs twice in the District Court, ultimately securing victory when the First Circuit affirmed the dismissal of claims, in a decision crystalizing the standard required to plead scienter in securities fraud cases.
Trial counsel to former CFO of $2.4 billion company based in China, in a securities class action in the Southern District of New York, relating to the company's 2011 financial collapse. Having obtained an $880 million default judgment against China-based corporate defendants, Plaintiffs alleged that the CFO had acted recklessly and made misstatements about the company's financial health. Secured a favorable jury verdict and resulting settlement requiring no monetary payment from the CFO.
Defended a leading national health care company in a False Claims Act action brought in federal court in South Carolina. Although the Department of Justice sought damages and penalties well in excess of $100 million, the matter settled for low seven figures.
Defended a public pharmaceutical company and its officers against Section 10(b) claims and Section 11 claims arising out of a secondary public offering and successfully obtained a motion to dismiss these claims on behalf of our client.
Represented a pharmaceutical company and its former Board of Directors in claims that the Board breached its fiduciary duty by not maximizing the value of its shares in the merger transaction. The Mintz team negotiated an excellent settlement for the company and the Board.

Drafted, on behalf of a coalition of domestic violence organizations, an amicus brief to the United States Supreme Court that advocated a ban on gun possession by all offenders convicted of misdemeanor domestic violence. In United States v. Hayes, 129 S. Ct. 1079 (2009), the Supreme Court ultimately decided the case in favor of the position advanced in the amicus brief, with the majority citing the brief in the opinion.
Advised construction firms with litigation and compliance issues arising out of state and federal public works projects, including the “Big Dig” project in Boston.
Assisted in the successful defense of the nation’s largest hospital chain from an attempt to enjoin one of the largest leveraged buyouts in history.

Jarkesy, holding that the SEC could no longer seek civil monetary penalties for fraud in its in-house courts consistent with the Seventh Amendment, which grants the right to a jury trial and thus requires such cases to be heard in federal court. The Supreme Court’s decision has potentially profound implications, not only for the SEC’s regulation of the securities industry, but for dozens of federal administrative agencies that, depending on the authorizing statute, can or must impose civil penalties through administrative proceedings.
