This tab lists judge-scoped rules only, and BenchPath has not yet published judge-specific rules for this judge — the courtroom also runs on the court's own rules and the statewide layer: 40 verified requirements may apply here. The Full Premium Report assembles every one of them, cited.
See all 40 in the Full Premium Report →No judge-level deadline on record runs shorter than a statewide deadline with the same trigger. The sentinel compares quoted timing across every published rule scoped to this judge on each visit — a clean result today is re-earned tomorrow.
No judge-scoped deadlines on this tab. Deadlines are extracted only when the source rule text states them — we never infer or calculate dates the rule does not explicitly contain. 29 rule deadlines apply in this courtroom across all layers — assembled with citations in the Full Premium Report.
Timing shown here is quoted from the rule text. Compute your actual date against the court's calendar and the rule itself — not legal advice.
Verbatim passages from opinions this judge authored for the court, quoted from the court's published PDF and hash-verified against it. The note under each quote restates only what the court itself said.
“Applying conventional statutory analysis, we conclude that “proceedings,” as used in section 2900.5, subdivision (b), is properly understood as referring to an individual criminal case.”
In everyday terms: The court concluded that “proceedings,” as used in Penal Code section 2900.5, subdivision (b), means an individual criminal case, so presentence custody credit is not automatically applied across multiple, distinct prosecutions merely because they are resolved and sentenced at a single hearing.
Verbatim excerpt reproduced from the court-published official slip opinion (hash-registered evidence document, sha256 ccecd6d0dbb9f68a...; authorship verified: “Opinion of the Court by Guerrero, C. J.”). The plain-language note restates only the reasoning stated in the opinion. Excerpt containment-verified against the slip’s text layer (Phase 6 custody text2/documents/S286297.txt, the PDF’s line breaks read as spaces); the page is the slip’s own, from its running header.
Quotes are reproduced verbatim from the court's published opinion; the plain-language note describes the court's stated reasoning only. Procedural information, not legal advice.
No verified ruling summary yet. BenchPath generates ruling summaries from opinion and docket corpora (CourtListener where covered) and publishes them only after human review — fabricated judicial analytics are exactly what this platform refuses to ship.
The attributed-opinion corpus holds California's appellate opinions as the Judicial Council posts them, from the listings BenchPath has read since October 2026 (each reaches back 120 days for published opinions and 60 for unpublished ones). The First, Third and Sixth Districts' unpublished opinions do not name the trial judge, so a ruling reviewed there is not attributed. Absence here is a coverage statement, never evidence about this judge.
