number of inhabitants" after each decennial census. At its first session, the Legislature
consisted of 70 members of the House of Representatives and 35 senators, and in 1890 and
again in 1901 members adjusted these numbers upward to match the state's population growth.
Few changes were made for the next thirty years, however, and by 1931 citizens

voters could pass an initiative to remedy the situation if the Legislature did not act.
The Washington attorney general said, "No," but the courts overturned his opinion and held
