When a vacancy occurs for a public member of a Trial Court Commission, the county board of supervisors member from the district in which the vacancy occurred appoints a nominating committee of seven persons from the district. Public notice is given that applications are being accepted for appointment to the commission. All applications, along with the committee's recommendations, are forwarded to the Governor. When a public member vacancy occurs on the Appellate Court Commission, the Governor appoints a nominating committee of nine members who solicit and review applications, and forward the names of all applicants, along with the committee's recommendation, to the Governor. Attorney members of the three commissions are recommended to the Governor by the State Bar of Arizona.
