3508.  (a) The governing body of a public agency may, in accordance with reasonable standards, designate positions or classes of positions which have duties consisting primarily of the enforcement of state laws or local ordinances, and may by resolution or ordinance adopted after a public hearing, limit or prohibit the right of employees in these positions or classes of positions to form, join, or participate in employee organizations where it is in the public interest to do so. However, the governing body may not prohibit the right of its employees who are full-time “peace officers,” as that term is defined in Chapter 4.5 (commencing with Section 830) of Title 3 of Part 2 of the Penal Code, to join or participate in employee organizations which are composed solely of those peace officers, which concern themselves solely and exclusively with the wages, hours, working conditions, welfare programs, and advancement of the academic and vocational training in furtherance of the police profession, and which are not subordinate to any other organization.(b) (1) This subdivision shall apply only to a county of the seventh class.(2) For the purposes of this section, no distinction shall be made between a position designated as a peace officer position by Chapter 4.5 (commencing with Section 830) of Title 3 of Part 2 of the Penal Code at the time of the enactment of the 1971 amendments to this section, and a welfare fraud investigator or inspector position designated as a peace officer position by any amendment to that Chapter 4.5 at any time after the enactment of the 1971 amendments to this section.(3) It is the intent of this subdivision to overrule San Bernardino County Sheriff’s Etc. Assn. v. Board of Supervisors (1992) 7 Cal.App.4th 602, 611, with respect to San Bernardino County designating a welfare fraud investigator or inspector as a peace officer under this section.(c) (1) This subdivision shall apply only to a county of the seventh class and shall not become operative until it is approved by the county board of supervisors by ordinance or resolution.(2) For the purposes of this section, no distinction shall be made between a position designated as a peace officer position by Chapter 4.5 (commencing with Section 830) of Title 3 of Part 2 of the Penal Code at the time of the enactment of the 1971 amendments to this section, and a probation corrections officer position designated as a peace officer position by any amendment to that Chapter 4.5 at any time after the enactment of the 1971 amendments to this section.(3) It is the intent of this subdivision to overrule San Bernardino County Sheriff’s Etc. Assn. v. Board of Supervisors (1992) 7 Cal.App.4th 602, 611, to the extent that it holds that this section prohibits the County of San Bernardino from designating the classifications of Probation Corrections Officers and Supervising Probation Corrections Officers as peace officers. Those officers shall not be designated as peace officers for purposes of this section unless that action is approved by the county board of supervisors by ordinance or resolution.(4) Upon approval by the Board of Supervisors of San Bernardino County, this subdivision shall apply to petitions filed in May 2001 by Probation Corrections Officers and Supervising Probation Corrections Officers.(d) The right of employees to form, join and participate in the activities of employee organizations shall not be restricted by a public agency on any grounds other than those set forth in this section.(Amended by Stats. 2002, Ch. 865, Sec. 1. Effective January 1, 2003.)
