Ill. Const. art. V, § 9

(a) The Governor shall nominate and, by and with the advice and consent of the Senate, a majority of the members elected concurring by record vote, shall appoint all officers whose election or appointment is not otherwise provided for. Any nomination not acted upon by the Senate within 60 session days after the receipt thereof shall be deemed to have received the advice and consent of the Senate. The General Assembly shall have no power to elect or appoint officers of the Executive Branch. (b) If, during a recess of the Senate, there is a vacancy in an office filled by appointment by the Governor by and with the advice and consent of the Senate, the Governor shall make a temporary appointment until the next meeting of the Senate, when he shall make a nomination to fill such office. (c) No person rejected by the Senate for an office shall, except at the Senate's request, be nominated again for that office at the same session or be appointed to that office during a recess of that Senate.
