Karl also represents individual employees, officers, and directors in civil litigation or regulatory matters arising from their employment. He has achieved successful outcomes for clients in state and federal courts nationwide, both at the trial and appellate levels, including:
- Negotiating voluntary dismissals and settlements to end hundreds of mass tort claims challenging drug information relating to Reglan, Accutane, Zoloft, Prozac, and Januvia;
- Obtaining dismissal of three amended securities fraud complaints and four parallel derivative complaints filed against a company and its senior executives;
- Successfully negotiating a class action settlement in a $1.6 billion health care fraud class action and defending the settlement against objections from class members in the U.S. Court of Appeals for the First Circuit; and
- Obtaining a favorable allocation of costs on behalf of an oil company facing environmental claims following a four-week bench trial.
Outside the courtroom, Karl helps businesses profit by identifying opportunities for cost reduction and revenue growth in relationships with business partners and customers.
