Section 6. Organization

(a) A majority of the members elected to each house constitutes a quorum.
(b) On the first day of the January session of the General Assembly in odd-numbered years, the Secretary of State shall convene the House of Representatives to elect from its membership a Speaker of the House of Representatives as presiding officer, and the Governor shall convene the Senate to elect from its membership a President of the Senate as presiding officer.
(c) For purposes of powers of appointment conferred by this Constitution, the Minority Leader of either house is a member of the numerically strongest political party other than the party to which the Speaker or the President belongs, as the case may be.
(d) Each house shall determine the rules of its proceedings, judge the elections, returns and qualifications of its members and choose its officers. No member shall be expelled by either house, except by a vote of two-thirds of the members elected to that house. A member may be expelled only once for the same offense. Each house may punish by imprisonment any person, not a member, guilty of disrespect to the house by disorderly or contemptuous behavior in its presence. Imprisonment shall not extend beyond twenty-four hours at one time unless the person persists in disorderly or contemptuous behavior.
