What You Need to Know Before Contacting a Conviction Integrity Unit

by Marissa Boyers Bluestine and Kia Hall Hayes

Over the past several years, more and more prosecutors have created conviction integrity units (“CIUs”), or conviction review units (“CRUs”), in their offices. While still primarily used in offices serving bigger cities, such as Philadelphia, Chicago, or Detroit, many offices in smaller jurisdictions are also developing processes to review wrongful conviction claims. Working with a CIU or CRU can have tremendous benefits for convicted individuals, but working with a unit carries very real risks, especially for someone working without an attorney. In the best case, the CIU could agree the applicant’s wrongful conviction claim merits relief and support vacating the conviction rather than fighting against the petition in court. But the CIU could also uncover information that opens the applicant or their friends and family members up to prosecution for new crimes or even jeopardizes the applicant’s options for parole and probation. For these reasons, incarcerated individuals applying to CIUs must understand the benefits and risks of working with a CIU before applying to one.

CIUs Generally

A CIU is a special unit within a state or county prosecutors’ office dedicated to reviewing claims of wrongful convictions from people convicted by that office. No state or county requires that a prosecutor’s office has a CIU. It is entirely within the elected or head prosecutor’s discretion to decide whether to have a unit or not and how that unit will run. There is no right to have a case reviewed by the unit, and any decision the DAs office makes about an application can’t be appealed.

What CIUs Do

The work CIUs do goes beyond investigating individual claims of wrongful conviction. Most CIUs are involved in creating policies for their offices and conducting trainings on the factors that lead to wrongful convictions such as faulty forensics, false confessions, or eyewitnesses led through a flawed identification procedure to make an incorrect identification. But at the center of the units’ operations is investigating wrongful convictions.

The types of cases CIUs investigate can vary from office to office. Some will only investigate cases where the applicant claims they had no involvement in the underlying crime (usually referred to as “actual” or “factual” innocence). Most will also investigate cases where the applicant claims their conviction “lacks integrity” due to procedural or constitutional violations.

These units usually have at least one staff attorney and often an investigator so they can conduct an independent investigation. During its investigation phase, a CIU often will take many steps to conduct a full re-investigation of a case. That could mean interviewing witnesses, finding witnesses who never testified at trial, conducting forensic or scientific testing of relevant evidence, reviewing police or other government files, and sharing those files with an applicant’s attorney. Because these investigations occur outside the regular proceedings of the judicial system, prosecutors aren’t focused on statutory or procedural issues. Rather, the purpose of the investigation is to determine whether the person convicted is the person who committed the crime.

If evidence developed or uncovered during the investigation proves the applicant’s innocence—of even if the evidence undermines the conviction to the point the prosecutors no longer have faith in it—the CIU can support the applicant’s request for post-conviction relief. Even if the evidence doesn’t prove the applicant’s innocence, CIUs can still work with an applicant’s counsel to negotiate a lower sentence or even reduced charges.

The goal of a well-functioning CIU is to review cases in as objectively as possible, without considering what legal arguments may have been made and rejected before. Where a DA’s office may have taken a position that a given conviction should stand, a CIU looks at the case in a different light by focusing on the facts, not the law or procedural defenses. Often—61 times in 2020 alonethose CIUs support a petition for vacatur (reversing a conviction) in court.

What Unrepresented People
Need to Know

Most people writing to CIUs are not represented by counsel. While some CIUs will not work with people who do not have an attorney representing them, many will. Indeed, for some units, pro se applications for assistance make up well over 70% of the cases under review.

But, while working with a CIU can provide hope, there are risks. People reaching out to a CIU need to know how that unit operates and be aware of not inadvertently waiving otherwise protected information.

First and foremost, attorneys who work in a CIU are not defense lawyers. They do not, and never will, represent someone who has written to them. They are prosecutors who investigate wrongful conviction claims, and they do not provide legal advice to people who have written to them. Nothing you say in person or in writing to a CIU lawyer is confidential—there is no protection for any of your communications with a CIU.

Because the CIU lawyers are prosecutors, everything you say to them in writing or in an interview can be used against you. It can be used against you for the case being reviewed or even for other criminal activity to which you were never prosecuted. In addition, in many states anything that is in a prosecutor’s file is subject to right to know or freedom of information laws. That means what you provide to a CIU can end up in the hands of a reporter or anyone else whose request to see the file is granted. Once you provide information to a CIU you can’t take it back.

As mentioned above, the CIU will conduct an investigation if they choose to review your case. An investigation means they will contact every person in the case or who has information about the crime. That could include your family members or loved ones.

The CIU Will Want to Talk with Your Lawyers

To conduct a thorough investigation, the CIU may want to talk to the attorneys who represented you at trial, on appeal, or in post-conviction proceedings. The CIU may also want to review your past attorneys’ files and the files of any attorney or innocence organization currently representing you or with whom you’re working.

You should understand your attorneys are required by law to keep confidential any information they learned about your case from representing you—including the contents of their files. They cannot share their knowledge of your case or their files with the CIU without your permission. You can choose to allow your attorneys to share this information if you want to.If a CIU requires you to waive attorney-client privilege to have your case reviewed, you should be very cautious.

Also, any communication between you and your attorneys—letters, conversations, messages, and so on—about the case is considered a privileged communication the attorney cannot reveal to the CIU without your permission.

You may not know all the information your former or present attorneys have in their files; they may have information linking you or people you know to a crime. You may need to decide if you will permit your past and any current attorneys to share what they know about the case, their communications to you and from you, and their case files with the CIU. In making that decision, you may want to consult with a lawyer who is not part of the CIU.

While the CIU may begin reviewing your application even if you decide not to share confidential information or files with the CIU, at some point they may need to speak with your lawyers. The CIU may advise you that their investigation cannot be completed and a decision cannot be made on your claim without speaking with your past attorneys and/or reviewing their case files. At that point, you will need to decide if you are willing to waive your rights and give your past lawyers permission to share their information, case files, and communications with you to the CIU.

Many times, when convicted individuals write to a prosecutor’s CIU, they send long letters talking about their prosecution, conviction, and appeal. But these narratives often have information which would otherwise be privileged: information about the legal strategy, things your lawyer said, and even why the person decided not to testify at trial are all topics that are privileged and that don’t have to be disclosed. If you reach out to a CIU or are completing paperwork for them, make sure to keep the communication focused solely on the facts of the case or what happened. Talking about anything related to conversations you had with your attorney or decisions you made after consulting with them could inadvertently waive those privileges going forward—even without you realizing you’ve done it.


The increase of CIU units nationwide has given wrongly-convicted individuals another potential avenue to win their freedom. But CIUs vary greatly in the cases they accept and in the way that they operate. CIUs review cases from a more objective viewpoint than the appellate unit of DAs offices, but CIU attorneys are still prosecutors, and working with them still carries great risks for incarcerated people, especially those without lawyers. Before reaching out to a CIU for help, incarcerated people need to understand how the CIU in their jurisdiction is run, and how working with them could potentially help or hurt their case.
