The 12th Arizona State Legislature, consisting of the Arizona State Senate and the Arizona House of Representatives, was constituted from January 1, 1935, to December 31, 1936, during Benjamin Baker Moeur's second term as Governor of Arizona, in Phoenix. The number of senators remained constant, while the number of representatives in the house decreased from 63 to 51. The Republicans broke the Democrats complete domination in the senate, managing to obtain a single seat, that of Apache County, however the house was entirely in Democratic hands.
The Legislature met for the Non regular session at the State Capitol in Phoenix on January 14, 1935; and adjourned on March 21.[1] There was a special session which ran from November 5–24, 1936.[2]
