(a) The supreme court shall establish criteria for determining the number and boundaries of judicial circuits and districts, and the number of judges needed in each circuit and district. If the supreme court finds that a need exists for increasing or decreasing the number of circuit or district judges, or for changing the boundaries of judicial circuits or districts, it shall, at the beginning of any session of the legislature, certify its findings and recommendations to the legislature.
(b) If a bill is introduced at any session of the legislature to increase or decrease the number of circuit or district judges, or to change the boundaries of any judicial circuit or district, the supreme court must, within three weeks, report to the legislature its recommendations on the proposed change. No change shall be made in the number of circuit or district judges, or the boundaries of any judicial circuit or district unless authorized by an act adopted after the recommendation of the supreme court on such proposal has been filed with the legislature.
(c) An act decreasing the number of circuit or district judges shall notaffect the right of any judge to hold his office for his full term.
