Former Beaumont ISD electrical contractor Calvin Walker will be required to face state prosecution alleging he defrauded the school district and the city of Port Arthur, according to a ruling by the United States Supreme Court (SCOTUS), as the court’s justices this week refused to entertain pleadings by Walker and his legal counsel that the cases pending against the defendant should be quashed before ever being heard by a jury of his peers. Walker is set to appear before Jefferson County Criminal District Court Judge John Stevens on June 5.
