Okla. Stat. tit. 63, § 63-686.5: Emergency interim successor defined - Qualification -

Tenure.

An emergency interim successor is one who is designated for

possible temporary succession to the powers and duties, but not the

office, of a legislator. No person shall be designated or serve as

an emergency interim successor unless he may, under the Constitution

and statutes hold the office of the legislator to whose powers and

duties he is designated to succeed, but no constitutional or

statutory provision prohibiting a legislator from holding another

office or prohibiting the holder of another office from being a

legislator shall be applicable to an emergency interim successor. An

emergency interim successor shall serve at the pleasure of the

legislator designating him or of any subsequent incumbent of the

legislative office.
