Petitioner, the County of Los Angeles, seeks a writ of prohibition to restrain the trial court from proceeding further with an action brought by the real party in interest, Shirley M. Hawley. 1 Mrs. Hawley filed her complaint on September 1, 1961, alleging that she suffered personal injuries caused by the negligence of employees of the Los Angeles County Hospital. Only her action against the *842 county is involved in this proceeding. The action was not brought to trial until November 25, 1964, because of the 1961 moratorium established by Civil Code section 22.3 on causes of action against public agencies. The county contends that the action must be dismissed because it is barred by the 1963 statutes governing the tort liability of public agencies. (Gov. Code, §§ 810-895.8.)
The facts are stipulated. On September 4, 1960, Mrs. Hawley was admitted to the Los Angeles County Hospital for barbiturate intoxication and alcoholism. On September 5, one of the attending physicians ordered that she be placed in “soft restraints,” that is, a tying of the hands to prevent injury to the patient. On September 6, a staff psychiatrist examined her, found that she had a “probably infantile personality,” and recommended her transfer to the psychiatric unit for observation. A health officer then applied for her emergency admission to the psychiatric unit on the ground that she was mentally ill and therefore likely to injure herself or others if not immediately hospitalized. (Welf. & Inst. Code, § 5050.3.) At about 4 p.m. on September 6, she was moved from the medical unit to the psychiatric unit. At about 5 p.m., while in the admitting room of the psychiatric unit, she fell from her bed and allegedly suffered a severe brain injury. A registered nurse was present and in charge of the admitting room. Mrs. Hawley was not being restrained with soft restraints or otherwise, and no bedrails were being used.
At the time of the injury, in September 1960, Mrs. Hawley could not have recovered against the county because of the common-law doctrine of sovereign immunity.
(Talley
v.
Northern San Diego Hosp. Dist.,
In
Muskopf
v.
Corning Hospital Dist.,
Government Code section 854.8 provides: “(a) [E]xeept as provided in [subdivision] ... (d) of this section, a public entity is not liable for:... (2) An injury to any person committed or admitted to a mental institution. . . . (d) Nothing in this section exonerates a public employee from liability for injury proximately caused by his negligent or wrongful act or omission.... [T]he public entity shall pay, as provided in Article 4 (commencing with Section 825) of Chapter 1 of this part, any judgment based on a claim against a public employee licensed in one of the healing arts under Division 2 (commencing with Section 500) of the Business and Professions Code for malpractice arising from an act or omission in the scope of his employment____” This section and other sections concerning mental institutions reflect the policy recommended by the Law Revision Commission. That policy *844 provides immunity for diagnosing, treating, confining, and releasing the mentally ill, but makes clear “that public entities and employees are liable for injuries caused by negligent or wrongful acts or omissions in administering or failing to administer prescribed treatment or confinement.” (4 Cal. Law Revision Com. Rep. 830; see Gov. Code, §§ 855.8, 856.) In this case, the placing of Mrs. Hawley in soft restraints or the using of bedrails are steps in administering a course of treatment, not in the decision whether to treat her. The employees can therefore be held liable for negligence in such administration, and the “public entity shall pay” any judgment against them according to the prescribed procedure. (Gov. Code, §§ 825-825.6.)
Under section 854.8, subdivision (d), the public entity cannot be directly sued to enforce its liability for negligence. That subdivision refers to article 4 of chapter 1, part 2 (Gov. Code, §§ 825-825.6), which provides the procedure whereby public entities pay judgments against their employees. First, however, there must be a judgment against an employee or employees licensed under division 2 of the Business and Professions Code, such as doctors, nurses, and psychiatric technicians. The 1963 legislation, therefore, limits the remedies that were available under Muskopf by making the county’s liability solely derivative.
Mrs. Hawley contends, however, that the 1963 legislation cannot be applied retroactively to restrict the county’s liability under
Muskopf.
She contends that although the Legislature can retroactively abrogate rights provided by statute, it cannot retroactively change the common law to abrogate a “vested right.” (See
Callet
v.
Alioto,
It is not unfair to apply the statute retroactively. Potential plaintiffs who were injured before the
Muskopf
case was decided clearly could not have relied on that case. (Cf.
Wells Fargo & Co.
v.
City & County of San Francisco,
*846
Mrs. Hawley contends, however, that section 854.8 denies her the equal protection of the laws on the ground that the county would be directly liable had she been injured in a medical ward rather than a mental ward. (See U.S. Const., 14th Amend.; Cal. Const., art. I, §§ 11, 21; Cal. Const., art. IV, § 25.) The Legislature has broad discretion in making classifications, and its decision will be upheld unless the classification has no reasonable relationship to any proper legislative purpose.

Notes
Mrs. Hawley, an incompetent, appears by her husband as guardian ad litem.
In 1963, the section was amended to provide only for criminal immunity. Civil immunity is now governed by Government Code sections 854-856.4.
