However, this article shall be subject to the Internal Revenue Code and Section 17 of Article XVI of the California Constitution. The administration of the requirements of this article shall comply with applicable provisions of the Internal Revenue Code and the Revenue and Taxation Code.

(2) Notwithstanding paragraph (1), this article shall not apply to the entities described in Section 9 of Article IX of, and Sections 4 and 5 of Article XI of, the California Constitution, except to the extent that these entities continue to be participating employers in any retirement system governed by state statute. Accordingly, any retirement plan approved before January 1, 2013, by the voters of any entity excluded from coverage by this section shall not be affected by this article.

(3) (A) Notwithstanding paragraph (1), this article shall not apply to a public employee whose interests are protected under Section 5333(b) of Title 49 of the United States Code until a federal district court rules that the United States Secretary of Labor, or his or her designee, erred in determining that the application of this article precludes certification under that section, or until January 1, 2016, whichever is sooner.

(B) If a federal district court upholds the determination of the United States Secretary of Labor, or his or her designee, that application of this article precludes him or her from providing a certification under Section 5333(b) of Title 49 of the United States Code, this article shall not apply to a public employee specified in subparagraph (A).

(4) Notwithstanding paragraph (1), this article shall not apply to a multiemployer plan authorized by Section 302(c)(5) of the federal Taft-Hartley Act (29 U.S.C. Sec. 186(c)(5)) if the public employer began participation in that plan prior to January 1, 2013, and the plan is regulated by the federal Employee Retirement Income Security Act of 1974 (29 U.S.C. Sec. 1001 et seq.).

(b) The benefit plan that is required by this article shall apply to public employees who are new members members, as defined in Section 7522.04.

(c) (1) Individuals who were employed by any public employer before January 1, 2013, and who became employed by a subsequent public employer for the first time on or after January 1, 2013, shall be subject to the retirement plan that would have been available to employees of the subsequent employer who were first employed by the subsequent employer on or before December 31, 2012, if the individual was subject to concurrent membership for which creditable service was performed in the previous six months or reciprocity established under any of the following provisions:

(A) Article 5 (commencing with Section 20350) of Chapter 3 of Part 3 of Division 5 of Title 2.

(2) An individual who was employed before January 1, 2013, and who, without a separation from employment, changed employment positions and became subject to a different defined benefit plan in a different public retirement system offered by his or her employer shall be subject to that defined benefit plan as it would have been available to employees who were first employed on or before December 31, 2012.

(d) If a public employer, before January 1, 2013, offers a defined benefit pension plan that provides a defined benefit formula with a lower benefit factor at normal retirement age and results in a lower normal cost than the defined benefit formula required by this article, that employer may continue to offer that defined benefit formula instead of the defined benefit formula required by this article, and shall not be subject to the requirements of Section 7522.10 for pensionable compensation subject to that formula. However, if the employer adopts a new defined benefit formula on or after January 1, 2013, that formula must conform to the requirements of this article or must be determined and certified by the retirement system’s chief actuary and the retirement board to have no greater risk and no greater cost to the employer than the defined benefit formula required by this article and must be approved by the Legislature. New members of the defined benefit plan may only participate in the lower cost defined benefit formula that was in place before January 1, 2013, or a defined benefit formula that conforms to the requirements of this article or is approved by the Legislature as provided in this subdivision.

(e) If a public employer, before January 1, 2013, offers a retirement benefit plan that consists solely of a defined contribution plan, that employer may continue to offer that plan instead of the defined benefit pension plan required by this article. However, if the employer adopts a new defined benefit pension plan or defined benefit formula on or after January 1, 2013, that plan or formula must conform to the requirements of this article or must be determined and certified by the retirement system’s chief actuary and the system’s board to have no greater risk and no greater cost to the employer than the defined benefit formula required by this article and must be approved by the Legislature. New members of the employer’s plan may only participate in the defined contribution plan that was in place before January 1, 2013, or a defined contribution plan or defined benefit formula that conforms to the requirements of this article. This subdivision shall not be construed to prohibit an employer from offering a defined contribution plan on or after January 1, 2013, either with or without a defined benefit plan, whether or not the employer offered a defined contribution plan prior to that date.

(f) (1) If, on or after January 1, 2013, the Cities of Brea and Fullerton form a joint powers authority pursuant to the provisions of the Joint Exercise of Powers Act (Article 1 (commencing with Section 6500) of Chapter 5), that joint powers authority may provide employees the defined benefit plan or formula that those employees received from their respective employers prior to the exercise of a common power, to which the employee is associated, by the joint powers authority to any employee of the City of Brea, the City of Fullerton, or a city described in paragraph (2) who is not a new member and subsequently is employed by the joint powers authority within 180 days of the city providing for the exercise of a common power, to which the employee was associated, by the joint powers authority.

(2) On or before January 1, 2017, a city in Orange County that is contiguous to the City of Brea or the City of Fullerton may join the joint powers authority described in paragraph (1) but not more than three cities shall be permitted to join.

(3) The formation of a joint powers authority on or after January 1, 2013, shall not act in a manner as to exempt a new employee or a new member, as defined by Section 7522.04, from the requirements of this article. New members may only participate in a defined benefit plan or formula that conforms to the requirements of this article.

(2) The formation of a joint powers authority on or after January 1, 2013, shall not act in a manner as to exempt a new employee or a new member, as defined by Section 7522.04, from the requirements of this article. New members may only participate in a defined benefit plan or formula that conforms to the requirements of this article.

(h) The Judges’ Retirement System and the Judges’ Retirement System II shall not be required to adopt the defined benefit formula required by Section 7522.20 or 7522.25 or the compensation limitations defined in Section 7522.10.
