There is hereby established an advisory committee to the Legislature of Oklahoma and to the Governor of Oklahoma. Such committee shall be composed of four (4) members of the Oklahoma Bar to be appointed by the Governor with the advice of the President of the Oklahoma Bar Association and two (2) members, at least one of whom is a member of the House of Representatives, to be appointed by the Speaker of the House of Representatives and two (2) members, at least one of whom is a member of the Senate, to be appointed by the President Pro Tempore of the Senate. Each member shall serve for four (4) years or until his death, resignation, or failure or refusal, certified by the remaining members, to perform his duties, renders his place vacant, whereupon the vacancy shall be filled in the same manner as the original appointment. In the event a legislative member fails to retain his seat in his respective house prior to the expiration of his term on the committee, his place on the committee shall be rendered vacant. The members of such committee, hereafter called commissioners, shall be the official commissioners of the State of Oklahoma to the National Conference of Commissioners on Uniform State Laws. They shall attend the annual meetings of such national conference. They shall report annually to the Legislature and to the Governor concerning the work of said conference and all other matters relating to their duties. They shall advise the Legislature and its committees concerning proposals for uniform and model state laws, the effect which such proposals would have on the law of this state, and such other matters as may be pertinent to desirable uniformity in legislation between this state and other states.
