Won “landmark” opioid trial for Endo Pharmaceuticals in a $50 billion action. Three of the most populous counties in California and the City of Oakland brought suit against opioid manufacturers alleging false advertising, unfair competition and public nuisance. The jurisdictions claimed that manufacturers’ alleged false and misleading marketing caused a $50 billion public nuisance. Obtained a full defense verdict following a four-month trial. The win was hailed as “giv[ing] drug companies their first major victory in the litigation brought by cities and counties across the country over the opioid crisis,” American Lawyer. (See “How Hueston Hennigan Notched A Landmark Opioid Trial Win,” Law360; “Opioid Makers Win Major Victory in California Trial,” New York Times; “Drug Makers Handed First Win Out of Thousands of National Opioid Crisis Lawsuits,” Newsweek).

Secured a complete dismissal of a putative class action lawsuit against PwC in relation to audit work performed for a publicly-traded company that is one of the largest diversified construction and construction materials companies in the United States.

Obtained a complete dismissal of felony charges against a prominent attorney and former principal of the Jacoby & Meyers law firm. Following more than five years of investigation and pre-indictment litigation, the Orange County D.A.’s Office charged Newport Beach attorney and entrepreneur Steven Mehr in a 47-count felony indictment in relation to his former role as a partner and principal of the Jacoby & Meyers law firm. Just eight months later, in the midst of an extensive evidentiary hearing in a related proceeding also handled by Hueston Hennigan, and following our filing of motions to dismiss the indictment and to recuse the D.A.’s Office and prosecutor for misconduct, we obtained a complete dismissal of all charges against Mr. Mehr and a termination of the related proceeding involving Jacoby & Meyers.
