Okla. Stat. tit. 51, § 51-131: Referenda and certification

(a) With respect to employees of the state in positions covered

by a retirement system established by the state, the Governor is

empowered to authorize a referendum upon the question of whether

service in positions covered by such retirement system should be

excluded from or included under an agreement, or modification

thereof, under Section 123 of this title; and, with respect to

employees of any political subdivision or instrumentality in

positions covered by a retirement system established by the state or

by such subdivision or instrumentality, the Governor, upon written

request of the governing body of such subdivision or

instrumentality, shall authorize a referendum upon the question of

whether positions covered by such retirement system should be

excluded from or included under a plan submitted by such subdivision

or instrumentality under Section 125 of this title. In either case

the referendum shall be conducted, and the Governor shall designate

an agency or individual to supervise its conduct, in accordance with

the requirement of Section 218(d) (3) of the Federal Social Security

Act; and the notice of referendum required by said Section 218(d)

(3) of the Federal Social Security Act shall contain, or shall be

accompanied by, a statement in such form and in such detail as the

agency or individual designated by the Governor to conduct such

referendum shall deem necessary to inform the eligible employees of

the rights which will accrue to them and their dependents and

survivors, and the liabilities to which they will be subject, in

event their services are included under such an agreement or plan.

(b) Upon receiving evidence satisfactory to him that, with

respect to any such referendum, the conditions specified in Section

218(d) (3) of the Federal Social Security Act have been met, the

Governor shall so certify to the appropriate federal agency.

(c) Nothing in this section shall be construed as allowing or

providing for coverage of services in a policeman's or fireman's

position, unless and until the Federal Social Security Act be

amended to allow coverage of services in such a position.
