Can a state district judge who, as a defense attorney, represented a criminal defendant years ago who went to TDCJ, then be the judge when that same defendant enters a guilty plea and goes back to TDCJ when one of the priors is used to enhance the defendant? This defendant is an habitual criminal. I heard it is a void judgment. The defendant did not complain and it was a plea bargain. Please help!

If the judge did not participate in the case that is currently pending before the judge, then article 30.01 does not require recusal. Long v. State , 137 S.W.3d 726, 736 (Tex.App.-Waco 2004); Bruns, 924 S.W.2d at 179 (citing cases).
