Wyoming Supreme Court Justices Lynne Boomgaarden and Kari Gray are standing for retention election on November 3, 2020. Both Boomgaarden and Gray were appointed by former Wyoming Governor Matt Mead (R).

Mead appointed all five of the justices currently on the court.

The governor appoints the five justices of the Wyoming Supreme Court with the assistance of a judicial nominating commission where neither the governor nor the Wyoming State Bar Association has majority control. The Wyoming Judicial Nominating Commission is made up of seven members: three lawyers (elected from the active membership of the Wyoming State Bar), three non-lawyer members (appointed by the governor), and is chaired by the chief justice of the supreme court.

New justices must face a retention election during the next general election after they serve at least one year on the bench. Justices then stand for retention every eight years. Since 2008, justices facing retention elections have won 98% of the time. In Wyoming, there has not been a single justice that lost retention during this same time frame.
