Federal Prison Grievance Approval Rate Fell from Nearly 7% to Under 2% Between 2000 and 2023, Analysis Finds

The Numbers

The Bureau of Prisons granted less than 2% of grievances in 2023, according to federal data analyzed by The Marshall Project and NPR. In 2000, that rate was just under 7%. Already low, it has collapsed over two decades.

That means for every 100 complaints filed by federal inmates, covering everything from denied medical care to physical abuse, at least 98 go unresolved in the inmate's favor.

One Case That Illustrates the Pattern

Terri McGuire Mollica was incarcerated at FCI Aliceville, a low-security federal women's prison in west Alabama. A prison doctor found a uterine fibroid in 2016. According to a lawsuit cited by The Marshall Project and NPR, it was small enough at the time for a simple, noninvasive surgery.

Prison officials never scheduled it.

By 2018, the same doctor documented the fibroid had grown to the size of a grapefruit, with Mollica's uterus distended as if she were nearly five months pregnant. She reported periods lasting nearly two weeks, pain she rated an 8 out of 10, and soaking through prison clothing. She was 50 years old.

Mollica's only formal recourse was the Bureau of Prisons' administrative remedy system: carbon copy forms, strict filing rules, submission to the warden, then the regional office, then Washington. She had weeks to file. Officials had months to respond. And the answer was almost always no.

When Mollica first tried to sue officials for neglect, a federal judge dismissed her case, ruling that she hadn't completed the grievance process. According to court records, she had tried to mail her final appeal to the bureau's office in D.C., but officials had never recorded it in the system. A decade after doctors first found the fibroid, she was still waiting for surgery. Given the delays, doctors recommend a full hysterectomy, according to her medical records. She was released to a halfway house in Alabama in January.

What the Grievance System Actually Is

The administrative remedy process is not optional busywork. A 1996 federal law requires prisoners to complete the internal grievance process before filing a lawsuit. If they fail to follow every requirement of that process, their case will likely be thrown out. That means the grievance system functions as a gatekeeper to the courts, not just an internal HR process.

If the system rejects 98 out of 100 complaints without meaningful review, it does not just fail as an oversight tool. It also creates a procedural barrier that can block valid civil rights lawsuits from ever reaching a judge. Many grievances are rejected without consideration for the content of the complaint, for reasons such as including too many pages or not filing enough copies.

The Bureau of Prisons' Response

The agency is aware of the drop in grant rates. A spokesperson said the bureau is working on "updates and additional guidance" related to filing grievances. "The program is intended to solve problems and be responsive to issues raised by inmates," Randilee Giamusso, a Bureau of Prisons spokesperson, wrote in an email, "and does not prevent inmates from pursuing litigation."

Giamusso noted that if prison officials don't reply within the established time frame, the filer can appeal to the next level without receiving a formal response. She declined to comment on Mollica's experience or any individual cases.

The Strongest Defense of the Current System

A fair reading of the data requires acknowledging the other side. Prison officials and Bureau of Prisons defenders have consistently argued that the vast majority of grievances are frivolous, duplicative, or filed improperly, and that a low approval rate may simply reflect a high volume of meritless filings. They also point out that prison resources are finite, that security concerns sometimes legitimately override medical scheduling, and that the bureau handles millions of inmate interactions annually.

That argument deserves a hearing. But it runs into a specific problem: the approval rate has dropped by roughly two-thirds since 2000. Prison conditions did not become proportionally less legitimate as a source of complaint over that period. Something changed in how the system processes and responds to claims, and the Bureau of Prisons has not offered a public explanation for the trend.

The Structural Problem

The grievance system was designed with oversight in mind. Congress, courts, and prison reformers across the political spectrum have long recognized that people inside federal facilities need a functional channel for complaints. That's not a liberal position. It's an accountability position.

Conservatives who care about government waste and abuse of power have as much reason to want a functioning prison grievance system as anyone. A federal bureaucracy that can ignore documented medical neglect with a rubber-stamp rejection form is the same bureaucracy that wastes taxpayer money and operates without accountability in every other context.

What's Not Known

The Marshall Project and NPR analysis draws on federal data through 2023, described as the last full year of data available.

Of all medical grievances decided in 2023, fewer than 1% were granted, according to the analysis. Across 24 years of prison filings, healthcare-related requests were the third most common reason for someone to lodge a complaint, behind housing problems and staff-related issues.

The unresolved question is whether Congress will treat a documented, two-decade collapse in grievance approvals as a policy failure requiring legislative intervention, or whether the data continues to sit in reports that nobody acts on.
