Tex. R. Civ. P. 18b
Comment to 2011 Change: Rule 18a governs the procedure for recusing or disqualifying a judge sitting in any trial court other than a statutory probate court, justice court, or municipal court. Chapter 25 of the Government Code governs statutory probate courts, Rule 528 governs justice courts, and Chapter 29 of the Government Code governs municipal courts. Under Rule 18a, a judge's rulings may not be the sole basis for a motion to recuse or disqualify the judge. But when one or more sufficient other bases are raised, the judge hearing the motion may consider evidence of rulings when considering whether to grant the motion. For purposes of this rule, the term "rulings" is not meant to encompass a judge's statements or remarks about a case.
The amendments to Rule 18b are not intended to be substantive.
