Okla. Stat. tit. 63, § 63-686.14: Termination of authority

The authority of emergency interim successors to succeed to the

powers and duties of legislators, the operation of the provisions of

this act relating to quorum, the number of affirmative votes

required for legislative action, and limitations on the length of

sessions and the subjects which may be acted upon shall expire two

(2) years following the inception of an emergency or disaster, but

nothing herein shall prevent the resumption before such time of the

filling of legislative vacancies and the calling of elections for

the Legislature in accordance with applicable constitutional and

statutory provisions. The Governor, acting by proclamation, or the

Legislature, acting by concurrent resolution, may from time to time

extend or restore such authority or the operation of any of such

provisions upon a finding that events render the extension or

restoration necessary, but no extension or restoration shall be for

a period of more than one (1) year.
