fine-print-class-action-lawsuit-los-angelesDeborah L. Pierce, an emergency room doctor in Philadelphia, was optimistic when she brought a sex discrimination claim against the medical group that had dismissed her. Respected by colleagues, she said she had a stack of glowing evaluations and evidence that the practice had a pattern of denying women partnerships. She began to worry, though, once she was blocked from court and forced into private arbitration.

Presiding over the case was not a judge but a corporate lawyer, Vasilios J. Kalogredis, who also handled arbitrations. When Dr. Pierce showed up one day for a hearing, she said she noticed Mr. Kalogredis having a friendly coffee with the head of the medical group she was suing.
