California Legislature 2026: the bills, and how each one ended

Fourteen bills, one object each, keyed to the 2025–2026 session. A bill is a proposal until a chamber says otherwise and a statute until a court says otherwise; this page keeps those states apart, and shows the date each was last verified.

Session closed September 30, 2026 · final outcomes recorded October 1, 2026

† Presumptive operative date under California’s default rule for statutes enacted in a regular session (January 1 of the following year); confirmed against each chaptered text as it is read. Counts and states on this page are generated from data/ca-2026-tracked-dossiers.json, itself derived from the 116-measure final ledger; nothing here is maintained by hand.

Archived snapshot — originally current through September 18, 2026, 3:00 PM PTPreserved as originally published. Superseded by the final status above; lifecycle language, deadlines and “pending” states in this section describe the record as it stood on that date, not the current state. “Gubernatorial phase underway”, “no gubernatorial action” and every per-bill state below describe the record on that date.

One object per bill, keyed to its session

A bill number is not an identifier. SB 942 in one session and SB 942 in another are different statutes, and a tracker keyed on the number alone will eventually attach one bill’s history to another. Every row below is keyed CA | 2025-2026 | <bill>, and each field is read from the chamber’s own action history rather than from a press summary.

AB 2575: four days from a failed vote to completed passage

The full sequence

28 August — third reading; passage refused 18–10; reconsideration granted 40–0; amended; ordered to second reading. 30 August — read second time; ordered to third reading. 31 August — read third time and passed the Senate 21–10; ordered to the Assembly; the Assembly took it without reference to file and concurred in the Senate amendments 51–16.

Current state

Legislative passage complete. Enrollment and presentment are the next recorded states and neither is established here. The bill is not law, is not operative, and the tool-inventory duty it would create is dated 1 July 2027 and depends entirely on enactment.

Why this bill is the case study

A publication that stored these facts as sentences on pages was wrong three times in four days. A publication that stores one versioned lifecycle object and derives every surface from it was wrong once per transition and corrected everywhere at once. The failed vote, the reconsideration, the amendment, the passage and the concurrence are five separate recorded actions — and only the fifth one completes passage.

What still needs reading

The 28 August Senate amendments have not been read in full. The amended text reaches clinical decision-support systems and health-care-worker use and override, in addition to the earlier inventory provisions. Analysis of those provisions is withheld until the enrolled text is read — the register says so rather than summarising a text nobody checked.

General rule: a refused passage vote followed by granted reconsideration is not a dead bill; a successful vote on an amended text in one house is not completed passage; and completed passage is not enactment. Full record: AB 2575 dossier.
