Mr. Carroll secured important wins for the pharmaceutical industry in the U.S. Court of Appeals for the First Circuit. In May 2016, the First Circuit affirmed the dismissal with prejudice of purported securities fraud class action cases against a major Boston pharmaceutical company. In doing so, the court emphasized that the plaintiff’s use of so-called “confidential witnesses” — even when there are many of them — is no substitute for specific factual allegations of fraud. In another frequently cited First Circuit win for a pharmaceutical company, the court emphasized that drug companies have no obligation to immediately publicly disclose even very negative adverse events of a drug and that securities laws permit — indeed, require — that issuers reasonably investigate important developments prior to public disclosure. Mr. Carroll, on behalf of a German-based global pharmaceutical and chemical company, also won denial of a preliminary injunction motion seeking to enjoin a shareholder vote on whether to approve the company’s proposed $7 billion acquisition of a Massachusetts-based life science company.
Mr. Carroll also has handled significant antitrust matters in the financial services and pharmaceutical industries. His recent engagements include the defense of a branded pharmaceutical company in a so-called “pay for delay” case and a case alleging collusion among private equity firms.
Mr. Carroll is handling a number of purported class actions for major national life insurers and is defending a variety of purported class and individual actions in the life, disability and casualty insurance contexts. He won an appeal for one of the nation’s largest mutual fund complexes that reversed a lower court’s refusal to dismiss three putative class actions involving allegations of improper mutual fund “market timing” activities. Mr. Carroll also represented investment advisers in regulatory inquiries and civil litigations in connection with the Bernard Madoff scandal. He also is defending one of the nation’s leading providers of variable annuities in class actions filed in multiple jurisdictions. Mr. Carroll regularly represents special committees and corporations in connection with derivative actions.
Mr. Carroll also is defending multiple ERISA class action cases, particularly in the financial services industry. In this regard he obtained a rare voluntary dismissal of a class action, pending in the Southern District of New York, against ERISA fiduciaries alleged to have ignored prudent risk concentration/diversification guidelines. He is currently defending several ERISA class actions alleging that plan participants paid excessive fees on a variety of investment options, including proprietary funds. In 2017, he successfully tried an ERISA class action to conclusion in the District of Massachusetts.
Mr. Carroll’s practice also includes representing corporations and individuals in matters before the SEC, the Massachusetts Attorney General’s Office and the Massachusetts Securities Division. His current engagements include matters before each of those regulators. He has defended a variety of civil enforcement actions and regulatory inquiries relating to allegations of misleading disclosure and claims that for-profit educational institutions violated state consumer protection laws.
Mr. Carroll has utilized the Private Securities Litigation Reform Act to obtain a rare denial of a class certification motion in a purported 10b-5 securities fraud class action. He also argued the first Rule 23 (f) class certification appeal accepted by the First Circuit.
Mr. Carroll often litigates a variety of covenant-not-to-compete and “employee raiding” cases on behalf of several Massachusetts high-technology firms. He also has experience trying cases before arbitration panels of FINRA and AAA. In addition, he has tried so-called “whistleblower” cases to an administrative law judge pursuant to Sarbanes-Oxley.
