List of justices of the Idaho Supreme Court
Wikimedia list article

Following is a list of justices of the Idaho Supreme Court. Idaho was made a territory on March 4, 1863, and the first justices of the Territorial Supreme Court were appointed by President Abraham Lincoln. Following statehood in 1890, the state constitution provided for three justices. By an amendment in 1919, the number was increased and fixed at five, composed of a chief justice and four associate justices, which commenced in January 1921 and remains the present size of the court.
The first female justice on the court was Linda Copple Trout, she was first appointed in 1992 and later served as chief justice. Cathy Silak was appointed the following year and was elected to the court in 1994, being the first woman to be elected to Idaho Supreme Court (Trout ran unopposed in 1996). Silak served through 2000, suffering the only election defeat for an incumbent on the court since 1944. Following the retirement of Trout in 2007, the court was all-male until the election of Robyn Brody in November 2016. With the appointment of Colleen Zahn in 2021 and Cynthia Meyer in 2023, the court currently has a female majority.
