Cal. Code Regs. tit. 9, § 865.2 – Good Cause for Denial of Rights.

(a) Rights listed in Section 861, except for that right listed in subdivision (g), may be denied only for good cause, and the rights under subdivision (f) may be denied only under the conditions specified in Article 7 (commencing with Section 5325) of Chapter 2 of Part 1 of Division 5 of the Welfare and Institutions Code. Good cause for denying a patient/resident the exercise of a right exists when the professional person in charge of a facility or his designee has good reason to believe:
1. (1) That the exercise of the specific right would be injurious to the patient/resident; or
2. (2) That there is evidence that the specific right, if exercised would seriously infringe on the rights of others; or
3. (3) That the institution or facility would suffer serious damage if the specific right is not denied; and
4. (4) That there is no less restrictive way of protecting the interests specified in (1), (2), or (3).
(b) The reason used to justify the denial of a right to a patient/resident must be related to the specific right denied. A right shall not be withheld or denied as a punitive measure, nor shall a right be considered a privilege to be earned.
(c) Treatment modalities shall not include denial of any right specified in Section 861 of this article. Waivers signed by the patient/resident or by the responsible relative/guardian/conservator shall not be used as a basis for denying Section 861 rights in any treatment modality.
