The Citizen Complaint Authority (CCA) was established in 2003 as a result of the Memorandum Agreement and the Collaborative Agreement (CA) between the U.S. Department of Justice and the City of Cincinnati. CCA is charged with investigation of serious interventions by City of Cincinnati police officers, including but not limited to use of force and discharge of firearms. Complaints may be referred to the Citizen Complaint Resolution Process (CCRP) under the Cincinnati Police Department (CPD). 
Any person who feels he or she has been the victim of police misconduct or a person who witnessed police misconduct may file a complaint in person, by telephone, by mail, or online. CCA will accept complaints by third parties. Complaints filed by citizens against Cincinnati police officers are available on the Open Data Portal.
The CCA Board typically meets the first Monday of each month to review completed investigations. Board meetings are open to the public.
