This opinion is the latest one of several disciplinary actions dealing with the various members of a firm that had represented multiple clients against the DuPont Corporation for crop damage caused by a fungicide. The lawyers were disciplined for violations of multiple rules ? including conflicts of interest, self-interest, and restrictions on representation ? because the firm was part of a secret side deal in which DuPont engaged the firm while the firm was still representing the plaintiffs. DuPont paid the firm more than $6 million at that time to prevent further litigation. The court rejected the referee’s recommended sanction of a public reprimand for the lead litigation attorney; suspended him for two years, and ordered disgorgement of his part of the fees received in the side agreement, plus interest.
