Conviction Integrity Units

A Conviction Integrity Unit (CIU) is a division of a prosecutorial office that works to prevent, identify, and remedy false convictions.

Several Conviction Integrity Units have accomplished a great deal in a short period of time, and there has certainly been an uptick in the number of offices that claim to have formed CIUs. It is still too soon to know whether this trend will produce a change in the way prosecutors operate generally. For more information on the history of CIUs, please see the annual report excerpts linked below.

Guide to the Registry's List of CIUs
The Registry maintains two lists:

(A) CIUs with recorded exonerations, and
(B) CIUS with no exonerations recorded.

Each table is sorted by state, and the units are listed alphabetically by county.
Clicking the "County" name hyperlink will take you directly to that unit's website.
Clicking the "No. of Exonerations" hyperlink will take you to an up-to-date exoneration count.
The following tables reflect data recorded in the Registry as of November 19, 2019.

Conviction Integrity Units - 3 February 2016
A look at the rapid rise in Conviction Integrity Units and their wide range in performance. The report concludes: “What we can say is this: In a few counties, CIUs have become important, active on-going operations. For several CIUs, it’s too early to say. And for others, we found no evidence that they have done anything much at all.” Read more.

About the Registry

The National Registry of Exonerations is a project of the Newkirk Center for Science & Society at University of California Irvine, the University of Michigan Law School and Michigan State University College of Law. It was founded in 2012 in conjunction with the Center on Wrongful Convictions at Northwestern University School of Law. The Registry provides detailed information about every known exoneration in the United States since 1989—cases in which a person was wrongly convicted of a crime and later cleared of all the charges based on new evidence of innocence. The Registry also maintains a more limited database of known exonerations prior to 1989.

Contact Us

We welcome new information from any source about exonerations already on our list and about cases not in the Registry that might be exonerations.
