judicial bias

The Supreme Court ruled 5-3 that when a judge had significant prior personal involvement as a prosecutor in a critical decision in the defendant’s case the judge must recuse himself or herself. 

District attorney Castille approved a subordinate prosecutor’s request to seek the death penalty against Terrance Williams. Williams was accused of a robbery and murder which he denied, on the stand, participating in.

Almost 30 years later Williams’s co-conspirator revealed that he had informed the prosecutor on the case that Williams and the victim had a sexual relationship that was the motive for the murder. A lower state court threw out Williams’s execution after discovering extensive prosecutor misconduct. 

Meanwhile, Castille had become Chief Justice of the Pennsylvania Supreme Court which was tasked with reviewing the lower court’s decision. The Pennsylvania Supreme Court unanimously reversed the lower court. Castille refused to recuse himself.
