McDermott Class Action Lawyers | Litigation & Dispute Resolution

Class Action


More than ever, class action litigation presents a risk for your business as plaintiffs’ lawyers become more sophisticated and aggressive in filing class actions.

Our litigators provide comprehensive counseling advice to prevent and, as needed, defend your company at all stages of class actions, including pre-filing resolutions of threatened claims, successful motions to dismiss and to compel arbitration, summary judgment grants, class certification denials, class de-certification and successful appeals of class certification rulings. With decades of experience and a strong track record, our representation has spanned issues of antitrust and unfair competition, ERISA and RICO liability, consumer fraud, deceptive business practices and product liability. Our team regularly provides counseling to avoid class actions, and we have also successfully defeated class actions and negotiated favorable settlements. Clients seek our counsel particularly for our ability to address the unique issues raised in healthcare, tax, employment, securities and consumer class actions.

  • Represented an American multinational e-commerce corporation in a denial of class certification and ensuing appeal relating to breach of contract claims and an alleged breach of the implied contractual duty of good faith and fair dealing against the client regarding its 2014 application of a new rating system of sellers on its platform. The tentative was to grant class certification on one of the two theories, but McDermott conducted oral argument and successfully convinced the Court to deny on both theories. The decision to deny class certification was thereafter appealed, which McDermott again successfully argued and won at Alameda Superior Court and the California Court of Appeal
