AB 1897 California Assembly · 2025-2026 Regular Session

Mentally disordered offenders: criteria for commitment.

Summary
Existing law requires that, as a condition of parole, a prisoner who has a severe mental health disorder be treated by the State Department of State Hospitals if the prisoner meets certain requirements, including, among others, that the person in charge of treating the prisoner and a practicing psychiatrist or psychologist from the State Department of State Hospitals have evaluated the prisoner and that a chief psychiatrist of the Department of Corrections and Rehabilitation certify to the Board of Parole Hearings that by reason of the prisoner's severe mental health disorder, the prisoner represents a substantial danger of physical harm to others. Existing law allows a prisoner to request a hearing before the Board of Parole Hearings for the purpose of proving that they meet the criteria to be treated by the State Department of State Hospitals. Existing law authorizes a prisoner who disagrees with the determination of the Board of Parole Hearings to file a petition in court in the county in which they are incarcerated or are being treated for a hearing on whether they met the criteria. This bill would require a psychiatrist or psychologist, when determining whether a prisoner represents a substantial danger of physical harm to others, to consider, among other things, the prisoner's history of violence that was related to their severe mental health disorder. The bill would also authorize the court, upon stipulation of the petitioner, prosecuting attorney, and defense counsel in the county of commitment to state prison, to conduct a hearing in the county of commitment to state prison.

MINOR
This diff reflects a reformatting of AB 1897 from a traditional legislative document layout (with page numbers, line numbers, and page headers) to a web-based presentation format. No substantive policy changes were made between these two versions; the legal text of Sections 2962 and 2966 of the Penal Code is identical in both.
TECHNICAL

The bill was reformatted from a traditional printed legislative document (with page headers, line numbers, and column layout) to a web-based presentation with navigation menus, search fields, and sidebar links.

Web interface elements were added including navigation links (home, accessibility, FAQ, feedback, sitemap, login), search functionality (Quick Search by Bill Number or Keyword), and bill information sidebar items (Votes, History, Bill Analysis, Compare Versions, Status, etc.).

Traditional legislative formatting elements were removed, including page numbers (95), page headers/footers (AB 1897, dash-page-dash patterns), and line-by-line numbering.
