What We Do

The Office of Administrative Courts (OAC) is Colorado's centralized administrative court system. Most States and the federal government have established similar specialized legal processes within the executive branch. This structure enables both agencies and citizens to have certain disputes resolved while avoiding the time and expense of litigation in district court. In 1976, the General Assembly created Division of Administrative Hearings as a central panel of administrative law judges (ALJ) to decide workers' compensation, human services, licensing, and a variety of other cases.

Be advised:  Pursuant to OAC Policy 5 -  Pleadings, documents and other written communications regarding a case at the Office of Administrative Courts must be addressed to the Clerk of the Office. Written communications should not be addressed to a specific judge or other staff member of the Office.
