Wyoming constitution
Article 5: judicial department
Section 5

Subject to the further provisions of this section, the legislature shall provide for the voluntary retirement and compensation of justices and judges of the supreme court and district courts, and may do so for any other courts, on account of length of service, age and disability, and for their reassignment to active duty where and when needed. The office of every such justice and judge shall become vacant when the incumbent reaches the age of seventy (70) years, as the legislature may prescribe; but, in the case of an incumbent whose term of office includes the effective date of this amendment, this provision shall not prevent him from serving the remainder of said term nor be applicable to him before his period or periods of judicial service shall have reached a total of six (6) years. The legislature may also provide for benefits for dependents of justices and judges.
