The nation's highest court announced on Monday it will not hear a former Beaumont ISD contract electrician's double jeopardy claims, clearing the way for a criminal trial in Jefferson County. Walker fought the charges, challenging the indictments in district court and the state appeals court before taking his case to the Supreme Court, arguing double jeopardy and violations of his Fifth Amendment right. The state also argued in a response filed in March that the tax offense Walker pleaded guilty to is "a separate offense" from those the state is seeking to try him for, and that the dismissal of the federal charges was "not turning on factual guilt or innocence," which state prosecutors said should allow for the dual-sovereignty claim. Walker's lawyers, DeGuerin and Stanford Law School's Jeffrey Fisher, argued in the petition that the court should at least put limits on dual-sovereignty, and accused state authorities of acting as "a sham and a cover" for the federal prosecutors.
