(2) When the battery specified in paragraph (1) is committed against a peace officer engaged in the performance of their duties, whether on or off duty, including when the peace officer is in a police uniform and is concurrently performing the duties required of them as a peace officer while also employed in a private capacity as a part-time or casual private security guard or patrolman and the person committing the offense knows or reasonably should know that the victim is a peace officer engaged in the performance of their duties, the battery is punishable by a fine of not more than ten thousand dollars ($10,000), or by imprisonment in a county jail not exceeding one year or pursuant to subdivision (h) of Section 1170 for 16 months, or two or three years, or by both that fine and imprisonment.

(d) When a battery is committed against any person and serious bodily injury is inflicted on the person, the battery is punishable by imprisonment in a county jail not exceeding one year or imprisonment pursuant to subdivision (h) of Section 1170 for two, three, or four years.

(e) (1) When a battery is committed against a spouse, a person with whom the defendant is cohabiting, a person who is the parent of the defendant’s child, former spouse, fiancé, or fiancée, or a person with whom the defendant currently has, or has previously had, a dating or engagement relationship, the battery is punishable by a fine not exceeding two thousand dollars ($2,000), or by imprisonment in a county jail for a period of not more than one year, or by both that fine and imprisonment. If probation is granted, or the execution or imposition of the sentence is suspended, it shall be a condition thereof that the defendant participate in, for no less than one year, and successfully complete, a batterer’s treatment program, as described in Section 1203.097, or if none is available, another appropriate counseling program designated by the court. However, this provision shall not be construed as requiring a city, a county, or a city and county to provide a new program or higher level of service as contemplated by Section 6 of Article XIII B of the California Constitution.

(2) Upon conviction of a violation of this subdivision, if probation is granted, the conditions of probation may include, in lieu of a fine, one or both of the following requirements:

(A) That the defendant make payments to a domestic violence shelter-based program, up to a maximum of five thousand dollars ($5,000).

(B) That the defendant reimburse the victim for reasonable costs of counseling and other reasonable expenses that the court finds are the direct result of the defendant’s offense.

For any order to pay a fine, make payments to a domestic violence shelter-based program, or pay restitution as a condition of probation under this subdivision, the court shall make a determination of the defendant’s ability to pay. In no event shall any order to make payments to a domestic violence shelter-based program be made if it would impair the ability of the defendant to pay direct restitution to the victim or court-ordered child support. If the injury to a married person is caused in whole or in part by the criminal acts of their spouse in violation of this section, the community property shall not be used to discharge the liability of the offending spouse for restitution to the injured spouse, required by Section 1203.04, as operative on or before August 2, 1995, or Section 1202.4, or to a shelter for costs with regard to the injured spouse and dependents, required by this section, until all separate property of the offending spouse is exhausted.

(3) Upon conviction of a violation of this subdivision, if probation is granted or the execution or imposition of the sentence is suspended and the person has been previously convicted of a violation of this subdivision or Section 273.5, the person shall be imprisoned for not less than 48 hours in addition to the conditions in paragraph (1). However, the court, upon a showing of good cause, may elect not to impose the mandatory minimum imprisonment as required by this subdivision and may, under these circumstances, grant probation or order the suspension of the execution or imposition of the sentence.

(4) The Legislature finds and declares that these specified crimes merit special consideration when imposing a sentence so as to display society’s condemnation for these crimes of violence upon victims with whom a close relationship has been formed.

(5) If a peace officer makes an arrest for a violation of paragraph (1) of subdivision (e) of this section, the peace officer is not required to inform the victim of their right to make a citizen’s arrest pursuant to subdivision (b) of Section 836.
