History

The 1849 constitution of California provided that the "number of Senators shall not be less than one third, nor more than one half of that of the members of the Assembly..." The 1849 constitution also provided that senators served two-year terms and were to be elected bienally, with the total number of senators being divided into two classes so that one half of the senators would be elected annually. Following the ratification of the 1879 constitution of California, the constitution prescribed that the senate is composed of 40 senators and that all senators must have resided within California for three years and their district for one year. Such districts were to be "as nearly equal in population as may be, and composed of contiguous territory". There was to be one senate district for each senator. Such districts were also required to preserve political boundaries: "In the formation of such districts, no county, or city and county, shall be divided, unless it contain a sufficient population within itself to form two or more districts; nor shall a part of any county, or of any city and county, be united with any other county, or city and county, in forming any district."

The lower tier dais runs across the entire chamber, there are several chairs and computers used by the senate officers, the most prominent seat is reserved for the secretary who calls the roll. The higher tier is smaller, with three chairs, the two largest and most ornate chairs are used by the president pro tempore (right chair) and the lieutenant governor (left chair). The third and smallest chair, placed in the center, is used by the presiding officer (acting in place of the pro tem) and is rarely sat in as the president is expected to stand. There are four other chairs flanking the dais used by the highest non-member officials attending the senate, a foreign dignitary or state officer for example. Each of the 40 senators is provided a desk, microphone and two chairs, one for the senator, another for guests or legislative aides.
