AB 416 California Assembly · 2025-2026 Regular Session

Involuntary commitment.

Summary
Existing law, the Lanterman-Petris-Short Act, authorizes the involuntary commitment and treatment of persons with specified mental disorders. Under the act, when a person, as a result of a mental health disorder, is a danger to self or others, or gravely disabled, the person may, upon probable cause, be taken into custody by specified individuals, including, among others, by a peace officer, a designated member of a mobile crisis team, or a professional person designated by the county, and placed in a facility designated by the county and approved by the State Department of Health Care Services for up to 72 hours for evaluation and treatment. Existing law authorizes county behavioral health director to develop procedures for the county's designation and training of professionals who will be designated to perform the above-described provisions. Existing law authorizes the procedures to include, among others, the license types, practice disciplines, and clinical experience of the professionals eligible to be designated by the county. Existing law exempts specified individuals, including a peace officer responsible for the detainment of a person under these provisions from criminal and civil liability for an action by a person who is released at or before the end of the period for which they were detained. This bill would require a county behavioral health director to include an emergency physician, as defined, as one of the practice disciplines eligible to be designated by the county when developing and implementing procedures for the designation and training of those professionals. The bill would also exempt an emergency physician who is responsible for the detainment of a person under those provisions from criminal and civil liability, as specified.

What changed between versions

05/07/25 - Amended Assembly 07/17/25 - Amended Senate · 5 edits · Jul 17, 2025
MODERATE
The Senate significantly narrowed AB 416 by removing the amendments to Sections 5008 and 5150 of the Welfare and Institutions Code, which had authorized emergency physicians to directly take persons into custody under a 72-hour involuntary hold. The Senate version retains only the requirement that counties must include emergency physicians as an eligible practice discipline in their designation procedures (Section 5121) and provides liability protection for designated emergency physicians (Section 5113). This shifts the bill from granting emergency physicians independent detention authority to requiring them to go through county designation before performing those functions.
Scope change
The bill's scope was substantially reduced. The Assembly version amended three code sections (5008, 5113, and 5150) and granted emergency physicians direct authority to detain individuals under a 72-hour hold. The Senate version amends only two sections (5113 and 5121) and limits its effect to requiring counties to recognize emergency physicians as an eligible practice discipline in their designation procedures, without granting independent detention authority.
SCOPE

The Senate removed the amendment to Section 5150, which had added 'emergency physician' as a person authorized to take someone into custody for a 72-hour involuntary hold. Emergency physicians can no longer independently detain individuals under this provision.

DEFINITION

The Senate removed the entire amendment to Section 5008, including the new definition of 'emergency physician' that had been added as subdivision (r). The definition now appears only within Section 5121(f)(3).

ELIGIBILITY

In Section 5121(f)(1), the requirement for counties to include emergency physicians was reworded from 'a professional who is eligible to be designated' to 'one of the practice disciplines eligible to be designated,' clarifying that emergency physicians are a category of practice discipline rather than an individual professional.

REQUIREMENT

In Section 5121(f)(2), the Senate added 'revocation' to the list of processes (training, application, approval, and revocation) that apply to all designated professionals including emergency physicians, ensuring counties can remove a designation if needed.

ENFORCEMENT

In Section 5113, the liability protection language was changed from 'the emergency physician designated pursuant to Section 5121' to 'the emergency physician professional person designated pursuant to Section 5121,' clarifying that the civil and criminal liability shield applies specifically to emergency physicians who have been formally designated as professional persons under the county's procedures.
