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.
