Conviction Integrity

Filing an Innocence Claim

Prosecutors play a special role in the criminal legal system. They must seek both truth and justice. Consistent with that duty, Michigan prosecutors have a legal duty to correct wrongful convictions. The Conviction Integrity and Expungement Unit’s (CIEU) goal is two-fold: both to prevent and correct wrongful convictions. 

The CIEU investigates claims of innocence to see if there is new evidence that supports those claims. The CIEU will make a recommendation to the Prosecuting Attorney and Chief Assistant Prosecuting Attorney about the appropriate remedy (if any) that should result from the Unit’s findings. The Prosecuting Attorney will make all final decisions about whether a remedy is appropriate. Only a court can grant any relief requested. 

If you would like the CIEU to review a case, please read the below and submit an application. If you need a hard copy of the application sent to you, please contact us at [email protected] or write to:

How will the CIEU communicate? 

  • The CIEU will communicate with lawyers for those applicants who are represented by attorneys.
  • The CIEU will communicate directly with applicants who are not represented by attorneys, NOT family members or friends who may have prepared the application on an applicant’s behalf (unless given authorization in writing directly from the applicant).

What can I expect from a CIEU investigation? 

If the CIEU investigates your case, it MAY:

  • Collect your case files from the prosecutor’s office, police agencies, courts, the Michigan Department of Corrections (MDOC), and other governmental entities.
  • Request additional information from you or others about your case.
  • Request that you authorize your trial attorney(s) to discuss your case with us. 

The CIEU will NOT:

  • Attempt to speak with your trial counsel without your written permission.
  • Provide your application or the materials you submit to the CIEU to other members of the Washtenaw County Prosecutor’s Office for prosecution purposes. Your information, however, may be shared with the Prosecuting Attorney and the Chief Assistant Prosecuting Attorney to discuss recommendations on your innocence claim.
