Thumbs Up to Federal Judge Pat Higginbotham, who’s been named to the 5th U.S. Circuit Court of Appeals by ! President Reagan.

He’ll be a needed antidote to the out-of-date liberalism of the 5th Circuit’s William Wayne Justice, who’s toyed disastrously with a number of Texas institutions, from elections to the prison system.
