The Osage Nation Congress shall establish the procedure for enactment of bills into law. No laws shall be made except by statute and no statute shall be enacted except by bill. No bill shall be passed without the concurrence of a majority of the members of the Osage Nation Congress. Each law shall embrace but one subject, which shall be expressed in its title. The enacting clause of each law of the Osage Nation shall be: “Be it enacted by the Congress of the Osage Nation.” Every bill that has passed by an affirmative majority vote shall be signed by the presiding officer of the Osage Nation Congress to certify that the procedural requirements for passage have been met and shall be presented forthwith to the Principal Chief for approval.
