The houses of each legislature shall adopt uniform rules of procedure. Each house may choose its officers and employees. Each is the judge of the election and qualifications of its members and may expel a member with the concurrence of two-thirds of its members. Each shall keep a journal of its proceedings. A majority of the membership of each house constitutes a quorum to do business, but a smaller number may adjourn from day to day and may compel attendance of absent members. The legislature shall regulate lobbying.
