On April 24, 2026, in the capital city of Pierre, South Dakota, a significant judicial appointment was announced by Governor Larry Rhoden. Magistrate Judge Chad Callahan was appointed to the role of circuit court judge in the Fourth Judicial Circuit, marking a new chapter in his esteemed career in law. This appointment fills the vacancy left by the retirement of Judge Michael W. Day, whose dedication and service have been pivotal to the judicial system in South Dakota for over a decade.
South Dakota, known for its rich heritage, diverse culture, and strong sense of community, plays a crucial role in shaping the balance between innovation and tradition in the heart of America. The Fourth Judicial Circuit, comprising Butte, Corson, Dewey, Harding, Lawrence, Meade, Perkins, and Ziebach counties, is at the forefront of this tradition. These counties are known for their distinct blend of Native American history, natural beauty, and agricultural might, making Judge Callahan’s role both significant and challenging as he steps into his new position.

Governor Rhoden expressed his confidence in Judge Callahan, noting, “Judge Callahan is a man of integrity who communicates clearly, calmly, and professionally. I have no doubt that he will uphold the rule of law, show care to everyone in his courtroom, and keep our state strong, safe, and free.”
Judge Callahan’s journey to this esteemed position began in Johnstown, Pennsylvania. He holds a bachelor’s degree in political science from the University of Pittsburgh Johnstown, completed in 1994, and went on to earn his juris doctorate from Ohio Northern University in 1998. These early academic pursuits paved the way for a career marked by both private practice and public service, offering him a comprehensive perspective on the legal landscape.
His professional journey in South Dakota began as a public defender in Pennington County, where he showcased his commitment to justice and advocacy for the community. From 2013 to 2017, he served as an assistant attorney general under then Attorney General Marty Jackley, further solidifying his reputation as a dedicated public servant capable of handling the complexities of modern law.
As he transitions into this new role, Judge Callahan expressed deep gratitude and a commitment to uphold the strong legal traditions of South Dakota. He stated, “I am truly honored and grateful that Governor Rhoden has chosen me. I will do my best to continue to earn his faith in me. I’d also like to acknowledge Judge Michael Day, who has served the Fourth Circuit as an attorney since 1983 and as a circuit judge for the last 13 years. He will be greatly missed as he begins his well-earned retirement.”
The Fourth Judicial Circuit of South Dakota is tasked with ensuring justice and equity in a region characterized by its vibrant communities and commitment to preserving the traditions and values of the state. With Judge Callahan’s appointment, the circuit court is positioned to continue its tradition of justice, fairness, and service with renewed vigor.
South Dakota’s Unified Judicial System, which includes the Supreme Court, Circuit Courts, and the State Court Administrator’s Office, benefits from a structure that supports these values. The Supreme Court serves as the highest authority on state law, while the Circuit Courts, such as the one Judge Callahan will be serving, handle criminal proceedings and civil litigation, ensuring that the rule of law is maintained across the state.
The people of South Dakota, with their diverse backgrounds and shared commitment to the common good, are central to the functioning of the judicial system. The appointment of leaders who embody these values is crucial, and Judge Callahan’s new role is met with widespread support and high expectations.
