Okla. Stat. tit. 63, § 63-686.12: Exercise of powers and duties by successors - Ouster

provisions applicable.

If, in the event of an emergency or disaster a legislator is

unavailable, the emergency interim successor highest in order of

succession who is not unavailable shall, except for the power and

duty to appoint emergency interim successors, exercise the powers

and assume the duties of such legislator. An emergency interim

successor shall exercise these powers and assume these duties until

the incumbent legislator, an emergency interim successor higher in

order of succession, or a legislator appointed or elected and

legally qualified can act. Each house of the Legislature shall, in

accordance with its own rules, determine who is entitled under the

provisions of this act to exercise the powers and assume the duties

of its members. All constitutional and statutory provisions

pertaining to ouster of a legislator shall be applicable to an

emergency interim successor who is exercising the powers and

assuming the duties of a legislator.
