Idaho Const. art. III, § 23

The legislature shall have no authority to establish the rate of its compensation and expense by law. There is hereby authorized the creation of the citizens committee on legislative compensation, which shall consist of six members, three to be appointed by the governor and three to be appointed by the supreme court, whose terms of office and qualifications shall be as provided by law. Members of the committee shall be citizens of the state of Idaho other than public officials holding an office to which compensation is attached. The committee shall, on or before the last day of November of each even-numbered year, establish the rate of compensation and expenses for services to be rendered by members of the legislature during the two-year period commencing on the first day of December of such year. The compensation and expenses so established shall, on or before such date, be filed with the secretary of state and the state controller. The rates thus established shall be the rates applicable for the two-year period specified unless prior to the twenty-fifth legislative day of the next regular session, by concurrent resolution, the senate and house of representatives shall reject or reduce such rates of compensation and expenses. In the event of rejection, the rates prevailing at the time of the previous session, shall remain in effect.

The officers of the legislature, including committee chairmen, may, by virtue of the office, receive additional compensation as may be provided by the committee. No change in the rate of compensation shall be made which applies to the legislature then in office except as provided herein.

When convened in extra session by the governor, no such session shall continue for a period longer than twenty days.
