Cal. Penal Code § 13701

(a) Every law enforcement agency in this state shall develop, adopt, and implement written policies and standards for officers’ responses to domestic violence calls by January 1, 1986. These policies shall reflect that domestic violence is alleged criminal conduct. Further, they shall reflect existing policy that a request for assistance in a situation involving domestic violence is the same as any other request for assistance where violence has occurred.
(b) The written policies shall encourage the arrest of domestic violence offenders if there is probable cause that an offense has been committed. These policies also shall require the arrest of an offender, absent exigent circumstances, if there is probable cause that a protective order issued under Chapter 4 (commencing with Section 2040) of Part 1 of Division 6, Division 10 (commencing with Section 6200), or Chapter 6 (commencing with Section 7700) of Part 3 of Division 12, of the Family Code, or Section 136.2 of this code, or by a court of any other state, a commonwealth, territory, or insular possession subject to the jurisdiction of the United States, a military tribunal, or a tribe has been violated. These policies shall discourage, when appropriate, but not prohibit, dual arrests. Peace officers shall make reasonable efforts to identify the dominant aggressor in any incident. The dominant aggressor is the person determined to be the most significant, rather than the first, aggressor. In identifying the dominant aggressor, an officer shall consider the intent of the law to protect victims of domestic violence from continuing abuse, the threats creating fear of physical injury, the history of domestic violence between the persons involved, and whether either person acted in self-defense. Notwithstanding subdivision (d), law enforcement agencies shall develop these policies with the input of local domestic violence agencies.
(c) These existing local policies and those developed shall be in writing and shall be available to the public upon request and shall include specific standards for the following:
1. (1) Felony arrests.
