Every justice of the Supreme Court or judge of the Court of Appeals who has served for eight years or more on the Supreme Court, the Court of Appeals, or the superior court, or as Administrative Officer of the Courts, or in any combination of these offices, and who while in active service becomes totally and permanently disabled so as to be unable to perform efficiently the duties of his office, and who retires by reason of such disability, shall receive for life compensation equal to two thirds of the annual salary from time to time received by the occupant or occupants of the office from which he retired. In determining whether a judge is eligible for retirement under this section, time served as district solicitor of the superior court prior to January 1, 1971, may be included. Whenever any justice or judge claims retirement benefits under this section on account of total and permanent disability, the Governor and Council of State, acting together, shall, after notice and an opportunity to be heard is given the applicant, by a majority vote of said body, make findings of fact from the evidence offered. Such findings of fact shall be reduced to writing and entered upon the minutes of the Council of State. The findings so made shall be conclusive as to such matters and determine the right of the applicant to retirement benefits under this section. Justices and judges retired under the provisions of this section are not subject to recall as emergency justices or judges. (1967, c. 108, s. 1.)
