Justice Gregory W. Moeller

Justice Gregory W. Moeller was appointed as the 58th justice of the Idaho Supreme Court on November 30, 2018, by Governor C. L. “Butch” Otter. He was reelected to a third term of office in May 2026 and assumed the role of Vice Chief Justice of the Court in October 2026.

In addition to his judicial duties, Justice Moeller chairs Idaho’s statewide Treatment Court, Felony Sentencing, and Media & the Courts Committees. He also serves as liaison to the Misdemeanor Sentencing Committee, Juvenile Justice Advisory Committee, and Tribal/State Court Council. For over fifteen years he has served in the New Judge Orientation Faculty, training new judges in jury-trial management and media relations. Justice Moeller is frequently invited to speak on legal topics statewide and nationally.

Justice Moeller is a 1981 graduate of South Fremont High School (St. Anthony, Idaho), where he helped lead the debate squad to the Class A state championship, won an individual state championship in extemporaneous speaking, and qualified for nationals in both events. From 1982 to 1984, he served a mission for his faith in Nagoya, Japan. Upon returning, he earned a bachelor’s degree in political science, magna cum laude, from BYU in 1987 and a law degree from BYU’s J. Reuben Clark Law School in 1990.

Immediately following law school, Justice Moeller joined the Rexburg law firm of Rigby, Andrus & Moeller, where he became a partner in 1994. Over 19 years in private practice, he focused on civil litigation, water law, and criminal defense, trying cases large and small across Idaho in both state and federal courts. From 2007 to 2009, he taught upper division classes in Media Law & Ethics as an adjunct professor at BYU–Idaho in Rexburg.

In 2009, Justice Moeller was appointed by Governor Otter to be a district judge. His resident chambers were in Madison County (Rexburg), but he presided over cases throughout the ten counties comprising the Seventh Judicial District—an area roughly the size of West Virginia. As a district judge, he presided over both the Upper Valley Drug and Mental Health Courts and served as a judicial representative on the Idaho Criminal Justice Commission and on the Region 7 Behavioral Health Board. He received the Professionalism Award from the Eagle Rock Inns of Court (2015) and was named Public Servant of the Year by the Rexburg Area Chamber of Commerce (2016).

Justice Moeller and his wife, Kathy, have been married for 41 years. They have five children and 15 grandchildren. Along with spending time with his family, Justice Moeller is passionate about college football, running, grilling, sushi, and updating his hot sauce collection (now over 180 bottles and counting). His most recent accomplishment was winning first place in the Idaho Supreme Court’s annual chili cook-off with his “Sweet, Sweet Flames of Justice” chili.
