All state prosecutors in Connecticut are appointed by the Criminal Justice Commission. The commission was established when the voters of Connecticut approved the 23rd Amendment to the State Constitution in 1984. The commission consists of the Chief State's Attorney and six members appointed by the Governor and confirmed by the General Assembly.

The Chief State's Attorney is appointed for a five-year term; the Deputy Chief State's Attorneys are appointed for four-year terms; and the thirteen State's Attorneys are appointed for eight-year terms. All other prosecutors (Assistant State's Attorneys) are appointed by the Criminal Justice Commission on the recommendation of the Chief State's Attorney and serve open-ended terms (until they retire, resign or are removed for just cause).
