Judge's Remarks Reveal Hostility
Patricia Patel sued her former employer in federal court. Before trial, the assigned judge told a colleague that Patel was a chronic complainer whose claims always lacked merit. Patel moved for recusal. The judge's expressed view of Patel required disqualification because it demonstrated personal bias against her.
Social Ties Create Bias Concern
Philip Powell was convicted of racketeering. The sentencing judge later attended a private dinner hosted by Powell and mingled with guests known for organized-crime ties. A disciplinary complaint followed. The judge's voluntary association with the convicted defendant and his circle created an appearance of impropriety warranting discipline.
