An appeal-stage worker has 20 days for the Petition for Reconsideration (25 by mail) and 45 days for the Writ of Review. In Laguna Hills, the underlying ruling comes from the Long Beach WCAB and the Petition is e-filed through EAMS the day the order arrives. Certified Specialist Eman Yazdchi (California Board of Legal Specialization, State Bar of California) drafts the Petition and preserves the writ.
It runs on three short clocks at the Long Beach WCAB: twenty days to file the Petition for Reconsideration, then forty-five days to seek writ review.
An appeal of a workers' compensation administrative law judge's decision is a Petition for Reconsideration under California Labor Code §5900 and California Labor Code §5903. For a Laguna Hills case decided at the Long Beach district office of the Workers' Compensation Appeals Board, the petition must be filed within 25 days of a mailed Findings & Award or 20 days of electronic service — the deadlines are jurisdictional, and a one-day-late filing kills the appeal. The petition is decided by the seven-commissioner WCAB en banc panel that sits over every California district office, and the panel either grants reconsideration (and issues a new decision) or denies it (which preserves the judge's original ruling).
Laguna Hills's workforce is built on the MemorialCare Saddleback Medical Center healthcare workforce, the Saddleback College commuter base, and Laguna Hills Mall area retail and service. Those industries produce the kinds of disputes that get appealed — apportionment fights under California Labor Code §4663, permanent disability ratings under California Labor Code §4660, denied medical treatment under California Labor Code §4600, contested temporary disability under California Labor Code §4650, and serious-and-willful misconduct petitions under California Labor Code §4553. A Laguna Hills worker on the losing end of any of those issues has the same 25-day window every California worker has.
Yazdchi Law's office is at 1125 W Avenue M-14 in Palmdale, about 110 miles south of Palmdale via the 14 to the 5. The firm appears at the Long Beach district office of the WCAB on the underlying Laguna Hills trials and files Petitions for Reconsideration with the WCAB en banc panel. Eman Yazdchi is a Certified Specialist in Workers' Compensation Law, certified by the California Board of Legal Specialization, State Bar of California. Appeals are a specialist-level corner of the practice — the petitions are written work, the deadlines are unforgiving, and the underlying record has to be built at trial.
A verified petition naming one of the five Section 5903 grounds, citing the trial record, and proposing the alternative order the worker wants.
A Petition for Reconsideration is the only path to challenge a Long Beach WCAB judge's decision on a Laguna Hills case. The petition is decided on the existing record, by the WCAB en banc panel in San Francisco, and the standard for grant is whether the judge's decision was supported by substantial evidence in light of the entire record. The grounds for reconsideration are limited to those listed in California Labor Code §5903.
California Labor Code §5903 lists five grounds: (a) the WCAB acted without or in excess of its powers; (b) the order was procured by fraud; (c) the evidence does not justify the findings of fact; (d) the petitioner discovered new evidence material to the petitioner, which could not, with reasonable diligence, have been produced at the hearing; and (e) the findings of fact do not support the order. A Laguna Hills apportionment appeal usually proceeds under §5903(c) (the evidence does not justify the apportionment percentage) or §5903(e) (the findings do not support the order). A new-evidence appeal under §5903(d) is rare and requires a sworn declaration explaining the diligence problem.
California Labor Code §5903 sets the deadline at 25 days from the date the decision is mailed by the Long Beach district office. Effective for decisions served electronically through EAMS, the deadline is 20 days from electronic service. The deadlines are jurisdictional — a one-day-late filing strips the WCAB en banc panel of jurisdiction and is dismissed without consideration of the merits. The verified deadline rule is 25 days mailed, 20 days electronic, never 30. A Laguna Hills worker who misses the deadline loses the right to appeal that decision permanently.
The WCAB en banc panel reviews the underlying trial record from the Long Beach district office and either grants or denies reconsideration. A grant is rare — published WCAB statistics show fewer than 15% of petitions are granted. A denial leaves the trial judge's decision intact and exhausts the workers' compensation administrative process. A grant produces a new decision (which can itself be challenged in the appellate courts under the writ-of-review path described below). For a Laguna Hills worker, the most common outcome is denial of reconsideration followed by a strategic call about whether the writ-of-review path under California Labor Code §5950 is worth pursuing.
After the WCAB en banc panel denies reconsideration — or grants it and issues a new decision the worker still disagrees with — the next step is a writ of review filed in the California Court of Appeal under California Labor Code §5950. The writ must be filed within 45 days of the WCAB's final decision; the standard of review is whether the WCAB acted in excess of its powers, the order was procured by fraud, the order was unreasonable, or the findings are not supported by substantial evidence. Writ-of-review filings are rare and have a low grant rate — the Court of Appeal typically denies them summarily — but for a high-value Laguna Hills apportionment or extraordinary-injury case the writ is the only path to appellate-court review.

Three deadlines drive every California workers' comp appeal: 20 days (electronic) or 25 days (mail service) for a §5900 Petition for Reconsideration; 30 days for a §4610.5 IMR appeal of a Utilization Review treatment denial; 25 days from the reconsideration denial for a §5950 Writ of Review to the California Court of Appeal.
Under California Labor Code §5903 a Petition for Reconsideration must rest on one of six specific grounds — (a) the appeals board acted without or in excess of its powers; (b) the order, decision, or award was procured by fraud; (c) the evidence does not justify the findings of fact; (d) the petitioner discovered new evidence that could not, with reasonable diligence, have been produced at hearing; (e) the findings of fact do not support the order, decision, or award; (f) any other matter required by law. A verified Petition for Reconsideration must be signed under penalty of perjury and served on every party and lien claimant on the same day it is filed with the appeals board.
The Petition is filed at the Long Beach WCAB district where the underlying Workers' Compensation Judge (WCJ) ruling was issued, then transmitted to the seven-member Workers' Compensation Appeals Board in San Francisco for review. After filing, the assigned trial-WCJ prepares a Report and Recommendation on Reconsideration; the appeals board then issues a written decision either granting the petition (which usually orders a rehearing on a defined issue, sometimes en banc) or denying it. If the petition is denied, the only remaining remedy is a §5950 Writ of Review to the California Court of Appeal — a discretionary writ the court may grant or summarily deny within 60 days.

Tap to call →Laguna Hills appeals run through the Long Beach WCAB on EAMS, with writ review heard at the California Court of Appeal in the appropriate appellate district.
The Long Beach district office of the Workers' Compensation Appeals Board is the trial-court venue for Laguna Hills cases on Yazdchi Law's calendar — the underlying Findings & Award or Findings & Order that gets appealed is issued by a Long Beach WCAB judge. The Petition for Reconsideration is filed through the EAMS electronic-filing system; the original record stays at the Long Beach district office while the en banc panel reviews it.
Laguna Hills's appeal-heavy disputes track the city's industries: apportionment fights under California Labor Code §4663 when the carrier's expert blames degenerative disc disease for a Laguna Hills cumulative-trauma claim; permanent disability rating disputes under California Labor Code §4660 when the AMA Guides 5th Edition WPI is contested; medical-treatment fights under California Labor Code §4600 when a Long Beach judge sides with the carrier's QME over the treating physician; and serious-and-willful misconduct petitions under California Labor Code §4553 when the underlying safety violation is contested.
Recurring Laguna Hills-area employers in the firm's reconsideration files include MemorialCare Saddleback Medical Center, the Saddleback College workforce, the Laguna Hills Mall redevelopment trades, and Saddleback Valley Unified School District. Self-insured employers and the larger national carriers are the most aggressive on reconsideration — they have in-house appellate counsel and they file defensively when a Laguna Hills worker wins at trial. The firm's job is to write the answer brief that holds the trial judge's findings together.
Emergency-department records from MemorialCare Saddleback Medical Center, Providence Mission Hospital Mission Viejo, and Providence Mission Hospital Laguna Beach are routinely the most decisive evidence in a Laguna Hills apportionment appeal — contemporaneous treating-physician documentation that places the injury at work, before any QME spin, before any carrier-attorney cross-examination. Preserving and citing those records in the answer brief is often what holds the trial-court decision on reconsideration.
