Determinative passage · p.3We first address the defendant’s objection to the notice of intent to impose sanctions. Per WCAB Rule 10832, “The Workers’ Compensation Appeals Bord may issue a notice of intention for any proper purpose, including, but not limited to: …(3)Sanctioning a party.” (Cal. Code Regs. tit. 8 § 10832.) A notice of intention (NIT) is neither an order, decision, or action ripe for removal or reconsideration. As such, the petition for removal as to the NIT is premature, and thus further proceedings on the issue of potential sanctions must be addressed by the WCJ in the first instance upon return of this matter. We agree with the WCJ that all parties must identify their full legal name including the names of the employer, insurance company, and any third-party administrator and failure to do so may subject the offending party to sanctions. (Cal. Code Regs., tit. 8, §§ 10390, 10400, 10402; DiFusco v. Hands On Spa et al (2025) 90 Cal.Comp.Cases __ (Appeals Bd. en banc); Coldiron v. Compuware Corp. (2002) 67 Cal.Comp.Cases 289 (Appeals Bd. en banc).) Moreover, all parties have an ongoing obligation to promptly update the official participant record if changes occur throughout the span of a case. (Cal. Code Regs., tit.
The Board agreed with the WCJ that failure to identify parties fully may subject to sanctions.
