What the panel ordered
Petition for Reconsideration granted; Order Imposing Sanctions and Costs against Patrick Petronella and Pacific MRI rescinded; matter returned to WCJ for further proceedings.
Lien claimant Pacific MRI seeks reconsideration of the Order Imposing Sanctions and Costs issued by the WCJ on November 21, 2025.
What was disputed, and how it came out
Each issue the panel decided, with the reasoning it gave. An outcome is what this panel did on this record — not a rule, and not a prediction.
The WCJ issued sanctions without holding a hearing or creating an adequate record, violating due process requirements; the WCAB granted reconsideration and rescinded the sanctions order.
From the decision · page 12For the foregoing reasons, IT IS ORDERED that lien claimant's Petition for Reconsideration is GRANTED. IT IS FURTHER ORDERED, as the Decision After Reconsideration of the Workers' Compensation Appeals Board, that the Order Imposing Sanctions and Costs Against Patrick Petronella and Pacific MRI issued by the WCJ on November 21, 2025 is RESCINDED and this matter is RETURNED to the trial level for further proceedings and decision by the WCJ consistent with this opinion.
The facts that decided it
What the panel treated as outcome-determinative, and which side it favoured.
Lien claimant withdrew the lien two days before the lien trial and did not appear at the trial.
Favours Applicant prevailed
This was the basis for the WCJ's sanctions order, but the WCAB found the record inadequate to support the sanctions.
From the decision · page 4"We are writing to you to inform that after detailed conversations and clarifications with all parties, our issue has been resolved and therefore withdraw our lien filed on February 23, 2024."
WCJ did not hold a hearing before issuing the sanctions order despite the lien claimant's timely objection.
Favours Applicant prevailed
Due process requires a hearing before sanctions; lack of hearing led to rescission of the order.
From the decision · page 11the Order of the NIT to Issue Sanctions and Award Costs. Due process requires that a party be provided with reasonable notice and an opportunity to be heard. (Katzin v. Workers' Comp. Appeals Bd. (1992) 5 Cal.App.4th 703, 711-712 [57 Cal.Comp.Cases 230].) A review of the record of proceedings does not indicate that before issuing the Order, the WCJ held a hearing in order to give Patrick Petronella and Pacific MRI an opportunity to be heard. The WCJ should have set this matter for a hearing pursuant to WCAB Rule 10421.
No evidence was admitted to the record to support findings of a pattern of conduct or frivolous litigation by the lien claimant.
Favours Applicant prevailed
Without evidence, the WCJ's findings could not be upheld, supporting reconsideration.
From the decision · page 10Moreover, to the extent that the NIT and Order reference lien claimant's failure to appear at the lien trial, thereby demonstrating a pattern of behavior, there is no evidence of a pattern of such conduct, as no evidence has been admitted to the record. There is further no evidence in the record relating to the filing of a frivolous lien claim as stated in the WCJ's Order.
The rules the panel named
Authorities as the decision cited them, with how this panel applied each one.
Cal. Code Regs., tit. 8, 10421(a)
Due process requires notice and opportunity to be heard before sanctions are imposed.
WCJ failed to hold a hearing before issuing sanctions, violating due process.
From the decision · page 11the Order of the NIT to Issue Sanctions and Award Costs. Due process requires that a party be provided with reasonable notice and an opportunity to be heard. (Katzin v. Workers' Comp. Appeals Bd. (1992) 5 Cal.App.4th 703, 711-712 [57 Cal.Comp.Cases 230].) A review of the record of proceedings does not indicate that before issuing the Order, the WCJ held a hearing in order to give Patrick Petronella and Pacific MRI an opportunity to be heard. The WCJ should have set this matter for a hearing pursuant to WCAB Rule 10421.
Cal. Code Regs., tit. 8, 10421(b)
Sanctions may be imposed for bad faith actions or tactics that are frivolous or solely intended to cause unnecessary delay.
The WCJ cited bad faith and frivolous litigation as grounds for sanctions but did not create an adequate record to support these findings.
From the decision · page 10Before issuing such an order, "the alleged offending party or attorney must be given notice and an opportunity to be heard." (Cal. Code Regs., tit. 8, § 10421(a) bold and italics added for emphasis.) WCAB Rule 10421, subdivision (b), authorizes sanctions for a party who has committed "[b]ad faith actions or tactics that are frivolous or solely intended to cause unnecessary delay including actions or tactics that result from willful failure to comply with a statutory or regulatory obligation, that result from a willful intent to disrupt or delay the proceedings of the Workers' Compensation Appeals Board, or that are done for an improper motive or are indisputably without merit." (Cal. Code Regs., tit. 8, § 10421(b).) Subdivision (b) provides a comprehensive but non-exclusive list of actions that could be subject to sanctions. As applicable here, violations subject to sanctions, pursuant to WCAB Rule 10421(b), include:
Cal. Code Regs., tit. 8, 10872(b)
Lien claimant must appear at hearings noticed prior to lien withdrawal unless excused by the WCAB.
Lien claimant failed to appear at the lien trial after withdrawing the lien, which may give rise to sanctions, but the record was inadequate to determine propriety.
From the decision · page 8(b) The lien claimant shall appear at any hearing that was noticed prior to the resolution or withdrawal of the lien unless excused by the Workers' Compensation Appeals Board. The lien claimant shall be excused from appearing at any subsequently noticed hearing.
What proof carried it
The evidence the panel weighed, by kind.
No evidence admitted to the record to support WCJ's findings of a pattern of conduct or frivolous lien claim.
From the decision · page 10Moreover, to the extent that the NIT and Order reference lien claimant's failure to appear at the lien trial, thereby demonstrating a pattern of behavior, there is no evidence of a pattern of such conduct, as no evidence has been admitted to the record. There is further no evidence in the record relating to the filing of a frivolous lien claim as stated in the WCJ's Order.
