A Petition for Disqualification of a Workers Compensation Judge was filed with the WCAB by an applicant attorney in a pending case. The basis of the Petition was that the WCJ expressed “an opinion regarding a legal or factual issue” during the course of the proceedings and before the case was litigated and resolved.
However the petitioner failed to “show that this opinion is a fixed one that could not be changed upon the production of evidence and the presentation of arguments at or after further hearing.”
After filing the Petition for Disqualification, but prior to any decision by the WCAB, a different WCJ approved a Compromise and Release between the parties. Once the issue in a petition is moot, or if the case is resolved in its entirety, the petition is subject to dismissal. Nonetheless, the WCAB went on to discuss the merits and then denied the Petition in the case of John Guy v AV Decking – ADJ9709184 (May 2025).
Labor Code section 5311 provides that a party may seek to disqualify a WCJ upon any one or more of the grounds specified in Code of Civil Procedure section 641. (Lab. Code, § 5311; see also Code Civ. Proc., § 641.) Among the grounds for disqualification under section 641 are that the WCJ has “formed or expressed an unqualified opinion or belief as to the merits of the action” (Code Civ. Proc., § 641(f)) or that the WCJ has demonstrated “[t]he existence of a state of mind … evincing enmity against or bias toward either party” (Code Civ. Proc., § 641(g)).
Under WCAB Rule 10960, proceedings to disqualify a WCJ “shall be initiated by the filing of a petition for disqualification supported by an affidavit or declaration under penalty of perjury stating in detail facts establishing one or more of the grounds for disqualification … .”
It has long been recognized that “[t]he allegations in a statement charging bias and prejudice of a judge must set forth specifically the facts on which the charge is predicated,” that “[a] statement containing nothing but conclusions and setting forth no facts constituting a ground for disqualification may be ignored,” and that “[w]here no facts are set forth in the statement there is no issue of fact to be determined.” (Mackie v. Dyer (1957) 154 Cal.App.2d 395, 399.
Furthermore, even if detailed and verified allegations of fact have been made, it is settled law that a WCJ is not subject to disqualification under section 641(f) if, prior to rendering a decision, the WCJ expresses an opinion regarding a legal or factual issue but the petitioner fails to show that this opinion is a fixed one that could not be changed upon the production of evidence and the presentation of arguments at or after further hearing. (Taylor v. Industrial Acc. Com. (Thomas) (1940) 38 Cal.App.2d 75, 79-80 [5 Cal.Comp.Cases 61].) – [Overruled on other grounds in Lumbermen’s Mut. Cas. Co. v. Industrial Acc. Com. (Cacozza) (1946) 29 Cal.2d 492, 499 [11 Cal.Comp.Cases 289] ].-
Additionally, even if the WCJ expresses an unqualified opinion on the merits, the WCJ is not subject to disqualification under section 641(f) if that opinion is “based upon the evidence then before [the WCJ] and upon the [WCJ’s] conception of the law as applied to such evidence.” (Id.; cf. Kreling v. Superior Court (1944) 25 Cal.2d 305, 312 [“It is [a judge’s] duty to consider and pass upon the evidence produced before him, and when the evidence is in conflict, to resolve that conflict in favor of the party whose evidence outweighs that of the opposing party.”].)
Also, it is “well settled … that the expressions of opinion uttered by a judge, in what he conceives to be a discharge of his official duties, are not evidence of bias or prejudice” under section 641(g) (Kreling, supra, 25 Cal.2d at pp. 310-311; accord: Mackie, supra, 154 Cal.App.2d at p. 400) and that “[e]rroneous rulings against a litigant, even when numerous and continuous, form no ground for a charge of bias or prejudice, especially when they are subject to review” (McEwen v. Occidental Life Ins. Co. (1916) 172 Cal. 6, 11; accord: Mackie, supra, 154 Cal.App.2d at p. 400.)
Similarly, “when the state of mind of the trial judge appears to be adverse to one of the parties but is based upon actual observance of the witnesses and the evidence given during the trial of an action, it does not amount to that prejudice against a litigant which disqualifies” the judge under section 641(g). (Kreling, supra, 25 Cal.2d at p. 312; see also Moulton Niguel Water Dist. v. Colombo (2003) 111 Cal.App.4th 1210, 1219 [“When making a ruling, a judge interprets the evidence, weighs credibility, and makes findings. In doing so, the judge necessarily makes and expresses determinations in favor of and against parties. How could it be otherwise? We will not hold that every statement a judge makes to explain his or her reasons for ruling against a party constitutes evidence of judicial bias.”].)
Under no circumstances may a party’s unilateral and subjective perception of bias afford a basis for disqualification. (Haas v. County of San Bernardino (2002) 27 Cal.4th 1017, 1034; Robbins v. Sharp Healthcare (2006) 71 Cal.Comp.Cases 1291, 1310-1311 (Significant Panel Decision).)
