The Lanterman–Petris–Short (LPS) Act (Chapter 1667 of the 1967 California Statutes, codified as Cal. Welf & Inst. Code, sec. 5000 et seq.) regulates involuntary civil commitment to a mental health institution in the state of California. It has been described as a "landmark" act which established the precedent for modern mental health commitment procedures in the United States. The bipartisan bill was co-authored by California State Assemblyman Frank D. Lanterman (R) and California State Senators Nicholas C. Petris (D) and Alan Short (D), and signed into law in 1967 by Governor Ronald Reagan. The Act went into full effect on July 1, 1972. It cited seven articles of intent:
To end the inappropriate, indefinite, and involuntary commitment of mentally disordered persons, people with developmental disabilities, and persons impaired by chronic alcoholism, and to eliminate legal disabilities; To provide prompt evaluation and treatment of persons with serious mental disorders or impaired by chronic alcoholism; To guarantee and protect public safety; To safeguard individual rights through judicial review; To provide individualized treatment, supervision, and placement services by a conservatorship program for gravely disabled persons; To encourage the full use of all existing agencies, professional personnel and public funds to accomplish these objectives and to prevent duplication of services and unnecessary expenditures; To protect mentally disordered persons and developmentally disabled persons from criminal acts. The Act in effect ended all hospital commitments by the judiciary system, except in the case of criminal sentencing, e.g., convicted sexual offenders, and those who were "gravely disabled", defined as unable to obtain food, clothing, or housing. It did not, however, impede the right of voluntary commitments. It expanded the evaluative reach of psychiatrists and created provisions and criteria for holds. Prior to 1987 it was assumed that the Act allowed involuntary treatment for those who were detained under an initial three-day hold (for evaluation and treatment) and a subsequent fourteen-day hospitalization (for those people declared after the three-day hold to be dangerous to themselves or others or gravely disabled). However, in the 1987 case of Riese v. St. Mary’s Hospital and Medical Center, the California Court of Appeal declared that these people had the right to exercise informed consent regarding the use of antipsychotic drugs, except in an emergency, and if they rejected medication "a judicial determination of their incapacity to make treatment decisions" was required before they could be involuntarily treated. This case was a class action suit brought in the name of person Eleanor Riese by the California ACLU. Eleanor Riese's story is depicted in the movie 55 Steps.
LPS evaluation, detention, and conservatorship process Under the LPS Act, individuals can be detained into a locked psychiatric facility in the following process:
5150 hold Under California Welfare and Institutions Code (WIC) 5150, an individual can be involuntarily placed in a locked psychiatric facility for an evaluation for up to 72 hours. Any peace officer or specific individuals authorized by a county government may place the hold. Three criteria apply – the individual is assessed to be a danger to themselves, a danger to others, or "gravely disabled". Per WIC 5008, grave disability is defined as an individual's lack of ability, due to their mental illness, to provide for their food, clothing, or shelter. In the case of children, it is the inability to use food, clothing, or shelter even if it is supplied. It is not uncommon for police to be the party who places them on the 5150 hold and then takes the individual to the hospital for further assessment. Over the next 72 hours, the hospital or psychiatrist must determine the individual's need for further locked psychiatric detainment. If the individual's condition clears up and they are no longer a danger to others or themselves or gravely disabled, they are released from the hospital. If, however, they remain a danger to others or themselves or continue to be gravely disabled, the hospital/psychiatrist may then request a 5250 hold to thereby keep the individual in the hospital beyond the 72-hour limit of the 5150 hold.
In popular culture Largely because many American movies and television programs are primarily produced in California, usage of the term 5150 has spread beyond its original location and user population. An album of the same name by the California hard rock band Van Halen was named directly for the code section, and several derivative uses followed. MGK’s 2022 album Mainstream Sellout features a song named for the term.
5250 hold If, after a 72-hour hold, an individual is deemed to still be a danger to others or themselves, or is gravely disabled, WIC 5250 permits an individual to be involuntarily held (in a locked psychiatric hospital) for an additional 14 days. Unlike a 5150 hold, a 5250 hold requires that the individual served receive a court hearing within 4 days of being served to ascertain the validity of the hold. Court hearings are often held in the hospital. Individuals are provided an attorney and a county court officer reviews the evidence for the hold presented by the hospital, hears the argument of the client and their attorney, and decides whether or not to uphold the 5250. Just as with the 5150 hold, during the 5250 hold, the individual is continually being assessed by psychiatric staff. Again, if the individual is (at any time) deemed to be no longer a danger or gravely disabled, they are then released from the hospital. According to section 5257 of the act, the individual must be released after 14 days, unless: they agree to further treatment on a voluntary basis, they are certified for an additional 14 days of intensive treatment, they are certified for an additional 30 days of intensive treatment, they are the subject of a conservatorship (commonly known as a Temporary LPS Conservatorship) petition, or they are the subject of a petition for post-certification treatment of a dangerous person.
