Cite: The Blackletter on California Workers’ Compensation § _._ (2026). Short form: Blackletter § _._  The section number is the primary pinpoint; each edition is also paginated, and a pin cite may add the edition page: Blackletter § 19.3, p. 43 (2026). Page numbers are permanent within an edition (editions are frozen); a new edition may repaginate, which is why the year binds the page.

Citing the corpus. Decisions of the Appeals Board are cited to the official reporter where published — Vazquez v. Renteria (2025) 90 Cal.Comp.Cases 514 (Appeals Bd. en banc) — with the Board’s case number preserved beside it for the evidence vault. Where no reporter citation is published, the case number stands alone and the docket marks it pending — never invented.

The census rule. This edition contains only the law stated in its corpus, quoted verbatim. The corpus of this printing is seven en banc decisions — every en banc decision of the Appeals Board for 2025 and 2026 to date, together with the Board’s en banc decisions in Dennis (2020) and Coldiron I & II (2002): Gaines v. ABM Aviation, Inc. (2026) ADJ20216367 et al., 30 pages; DiFusco v. Hands On Spa (2025) ADJ7445107, 90 Cal.Comp.Cases 1007, 17 pages; Perez v. Chicago Dogs (2025) ADJ16597333 (order granting reconsideration; final decision deferred), 16 pages including its Opinion and Order Correcting Clerical Error; Vazquez v. Renteria (2025) ADJ11017003, 90 Cal.Comp.Cases 514 (decision after reconsideration; holdings prospective), 17 pages; Dennis v. State of California (2020) ADJ9346293, 85 Cal.Comp.Cases 389 (decision after reconsideration), 22 pages; Coldiron v. Compuware [Coldiron I & II] (2002) SRO 0088351, 67 Cal.Comp.Cases 289 and 1466 (notice of intention; decision after reconsideration; image-proofread transcripts), 16 pages — each retrieved from dir.ca.gov and machine-verified. Statutes, regulations, and earlier decisions appear only as, and exactly as, those decisions quote them. If it is not in the corpus, it is not in the book. Sections awaiting authority are marked reserved and are blank.

Weight. En banc decisions of the Appeals Board are binding precedent on all Appeals Board panels and workers’ compensation administrative law judges (see § 1.1). With one exception, the grades in this printing are ● settled on that basis, within the four corners of the corpus; § 20.3 is graded ◐ preliminary while the Perez final decision remains deferred.

Section headings, grades, and cross-references are finding aids; the quotations are the book. Free to read, always. Not legal advice; not a government publication. Free official help for injured workers: DWC Information & Assistance, 1-800-736-7401, dir.ca.gov. Corrections: /about. The engine: U.S. Pat. App. No. 19/782,460 (patent pending). The machinery is patent-pending; the law is free.

Preface

Every treatise before this one asked its reader to trust an author. The author read the cases, decided what mattered, and restated the law in the author’s words — and the reader’s confidence rested, finally, on the author’s care. This book makes a different offer. It contains no restatements. Every sentence of law in its body is a court’s sentence, quoted verbatim, checked by machine against the source it came from, and shelved at the address where the doctrine lives. Where the courts have not spoken, the page says so and stands blank. Where they disagree, the fork is shown, not smoothed.

The book is compiled by a census, not a selection: every rule-stating line of every decision in its corpus is here, and the corpus of each printing is stated on its edition page. A blank chapter is not unfinished work — it is an honest report that the corpus has not yet reached that shelf. As the corpus grows, the book grows, in public, with its changelog, and nothing once printed is ever silently altered: revisions supersede; they do not erase.

My part is the arrangement, the apparatus, and the promise that the machine checked every quotation — a compiler’s part, not an author’s. The law belongs to the courts that wrote it and to the workers and employers it governs. It is presented here free, to everyone, because the law of California should cost nothing to read.
