Conviction Integrity Units

A Conviction Integrity Unit (CIU) is a division of a prosecutorial office that works to prevent, identify, and remedy false convictions. They are sometimes called Conviction Review Units (CRUs).  

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, or the website of that State/District Attorney's office, if they do not have a dedicated webpage to their CIU.

Clicking the "Exonerations" hyperlink will take you to an up-to-date exoneration count.

The following tables reflect data recorded in the Registry as of April 14, 2021.

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.
