1. Subject to the limitations of sections 86.1310 to 86.1640, the retirement board shall, from time to time, establish policies for the administration of its assets, for the transaction of its business and for the conduct of nominations and elections of the elected members of the retirement board. The retirement board shall be deemed to be a state agency within the meaning of chapter 536. Any rule or portion of a rule, as that term is defined in section 536.010, that is created under the authority delegated in this section shall become effective only if it complies with and is subject to all of the provisions of chapter 536 and, if applicable, section 536.028. This section and chapter 536 are nonseverable and if any of the powers vested with the general assembly pursuant to chapter 536 to review, to delay the effective date, or to disapprove and annul a rule are subsequently held unconstitutional, then the grant of rulemaking authority and any rule proposed or adopted after August 28, 2005, shall be invalid and void.

2. The retirement board shall elect from its membership a chairman, a vice chairman, and a treasurer and shall, by majority vote of its members, appoint a secretary, who may be, but need not be, one of its members. The offices of secretary and of treasurer shall not be held by the same person. It may employ such actuarial, legal, and other services as may be necessary to transact the business of the retirement system. The compensation of all persons employed by the retirement board and all other expenses of the board necessary for the operation of the retirement system shall be paid in such manner as the retirement board shall determine; provided, that the compensation of such persons as may be employed by the retirement board shall not be greater than the compensation paid for comparable abilities by the governments of the cities in which the retirement board is located.
