An act to amend Section 849 of the Penal Code, and to amend add Section 631 of 631.2 to the Welfare and Institutions Code, relating to criminal procedure.
SB 821 would require California courts to make a prompt judicial probable-cause review after a warrantless arrest, no later than 48 hours after the arrest, for adults who remain in custody. If the court finds no probable cause, the person must be released immediately and the release order must be communicated to the person in custody and the arrested person. The bill also allows the initial review to be based on sworn statements or a police report, conducted in chambers or remotely, and to occur at arraignment or another qualifying proceeding.
For juveniles, the bill creates a parallel 48-hour probable-cause review requirement and removes current exceptions that can delay review, including the judicial-holidays exemption and the petition exemption. It also expands probation-officer written review and approval requirements for detaining a minor more than 24 hours from certain misdemeanor cases to all crimes, and requires written explanations when a minor is held more than 24 hours and later released without a petition being filed. The bill states that these initial probable-cause findings are not binding in later hearings.
The bill would amend Penal Code Section 849 and add/modify juvenile detention provisions in the Welfare and Institutions Code, including new Section 631.2. It would shorten and standardize the timeline for judicial review of warrantless arrests, codify a 48-hour probable-cause rule for adults and juveniles, and require recordkeeping on arrest time, review time, and materials relied on by the court. It would also increase procedural obligations for courts, prosecutors, law enforcement, jails, probation departments, public defenders, and indigent defense providers, and it is designated a state-mandated local program with potential reimbursement if mandated costs are found.
The bill appears to have been received favorably in committee, at least procedurally: it advanced on a unanimous 5-0 vote and later was placed on the suspense file by a 6-0 vote, indicating no recorded opposition in the available votes. The bill’s findings frame it as a constitutional and due-process measure intended to align California law with U.S. Supreme Court precedent on prompt judicial review after arrest. Overall, the available record suggests support for the bill’s goals, while also reflecting fiscal scrutiny through the appropriations process.
The main points of contention are likely operational and fiscal rather than philosophical: the bill would require courts and local justice agencies to process probable-cause determinations within 48 hours, including weekends and holidays in juvenile cases, which may strain staffing and scheduling. It also expressly seeks to override existing juvenile-case precedent allowing later review, and to remove current exemptions that can delay release or review, which could be controversial for prosecutors, probation departments, and court administrators. The bill’s mandate/reimbursement language signals concern about local implementation costs, which likely contributed to its referral to Appropriations and suspense-file placement.
