California Code, Government Code - GOV § 22203

Notwithstanding Section 22201, before the board shall execute on behalf of the state an agreement with the federal agency as provided in this chapter, the public agency and the board shall enter into a written agreement, that shall include provisions not inconsistent with this part that the board deems necessary in the administration of the federal system as it affects the state and the public agency and its employees.

For the purposes of this section, the state shall not be deemed to be a public agency, but nevertheless an agreement entered into pursuant to this part by the board and the Teachers' Retirement Board or the Adjutant General or the Regents of the University of California or the governing body of a public agency, as defined in Section 22009.03, shall be deemed to be entered into by the board and a public agency.
