A California appeals court on Monday rejected Roman Polanski's bid to have his 32-year-old sex case dismissed, but cited grave concerns over possible judicial and prosecutorial misconduct. "We encourage all participating parties to do their utmost to ensure that this matter now draws to a close in a manner that fully addresses the issues of due process and fundamental fairness raised by the events of long ago," the court's opinion stated. While a blow to Polanski's efforts to have the case dismissed and win his freedom from Swiss authorities, the ruling cast serious doubt on how the case was handled.
