Workers' Comp Appeal Attorney in Lancaster, California

What Are the Legal Grounds for Appealing a Lancaster Workers' Comp Decision?

Under LC SS5903, a Petition for Reconsideration must identify specific legal grounds — you cannot simply argue that you disagree with the result. The WCAB Appeals Board panel will grant reconsideration only if it finds one or more of the following recognized errors in the judge's decision:

The Five Grounds for Appeal

• Error of law — The judge misapplied a statute, regulation, or binding precedent. For example, applying the wrong apportionment standard to a Lancaster solar worker's cumulative trauma claim, or misinterpreting the MTUS guidelines when reviewing a treatment denial for a BYD Motors assembly worker.
• Insufficient evidence — The decision is not supported by substantial evidence in the record. If the judge relied exclusively on the insurer's QME report while disregarding your treating physician's well-documented opinions, the evidentiary basis is attackable.
• New evidence — Material evidence that was not available at the time of trial. A post-trial MRI revealing a disc herniation not visible on earlier imaging, or a specialist report completed after the hearing date.
• Irregularity in proceedings — Procedural errors that denied you a fair hearing. The judge improperly excluded evidence, cut off testimony, or failed to address issues properly raised by the parties.
• Exceeded jurisdiction — The judge ruled on issues not properly before the court or issued orders beyond their statutory authority.

The Appeal Timeline for Lancaster Cases

Time is compressed in workers' comp appeals. Missing any deadline can permanently close your path to reversal:

• Day 0 — Judge's Findings and Award issued at the Van Nuys WCAB
• Day 20 (25 if served by mail) — Absolute deadline to file your Petition for Reconsideration under LC SS5903
• Within 60 days of filing — The WCAB Appeals Board panel issues its decision: grant, deny, or dismiss
• 45 days after panel denial — Deadline to file a Writ of Review with the California Court of Appeal under LC SS5950

Writ of Review: Taking Your Case to the Court of Appeal

If the WCAB panel denies your Petition for Reconsideration, the fight does not end. A Writ of Review under LC SS5950 takes your case to the California Court of Appeal — a higher court with the power to overturn WCAB decisions on questions of law. Writs are granted selectively, but they are critical in cases involving novel legal issues, significant evidentiary disputes, or constitutional questions. We have pursued Writs of Review for Lancaster workers when the stakes and the legal merits warranted appellate court scrutiny.

What Happens to Your Benefits During the Appeal?

Filing a Petition for Reconsideration does not automatically stay the judge's order. If the decision awarded you benefits, the insurer must generally continue paying while the appeal is pending. If the decision denied or reduced your benefits, filing the petition preserves your right to challenge the ruling but does not automatically restore payments. In appropriate cases, we petition for a stay of adverse orders to protect Lancaster workers from financial harm during the appellate process.
