The prisoners write in carefully lettered script or on old electric typewriters. There are sometimes grammatical errors or misspellings. But the language is direct. They describe facing Stage 4 cancer after their symptoms went undiagnosed for years. The denial of orthotic shoes to treat a diabetic condition that led to a severe wound and amputation. Nineteen years locked in solitary confinement.

Some describe beatings and sexual assaults by fellow prisoners that they say corrections officers failed to prevent. Others say they were assaulted by officers themselves.

The Eighth Amendment, which bars "cruel and unusual punishments," was intended by the founders as a bulwark against prisoner abuse. Over the years it came to mean any treatment that "shocked the conscience." But prisoners and civil-rights attorneys have said that it is now nearly impossible to win such claims in court.

To investigate whether that constitutional protection holds, a Business Insider team read tens of thousands of pages of court records for nearly 1,500 Eighth Amendment complaints, including every appeals court case with an opinion we could locate filed from 2018 to 2022 citing the relevant precedent-setting Supreme Court cases and standards. We reviewed hundreds of pages of training materials, medical records, incident reports, and surveillance footage. We read cases from prisoners convicted of violent and nonviolent crimes — some who have spent decades behind bars for murder or sexual assault, others sentenced to short stints for marijuana possession or third-degree assault. We spoke with more than 170 people, including prisoners and their families, attorneys and legal scholars, correctional staff and prison healthcare providers, and current and former federal judges.

We uncovered a near evisceration of protections for this nation's 1.2 million prisoners, largely propelled by legal standards and laws put into place at the height of the war on drugs.

In our analysis, plaintiffs prevailed in only 11 cases, including two class actions — less than 1%.

"If a right is unenforceable, then it's not much of a right," Paul Grimm, a former federal judge for the District of Maryland, said after reviewing BI's findings. "It is essentially unavailable."

One Tennessee prisoner wrote a letter to the court after failing to overcome these steep odds in his own case.

"To everyone I tried to talk to and ask to file grievances and complaints to bring the wrongs to light," he wrote, "I'm sorry that I tried to bring hope and law and order to a place that has no hope or process of order."

Failed oversight

Over decades, federal and state oversight agencies have repeatedly found that US prison systems have failed to protect prisoners in their care. Just this year, an inspector general found that staff in federal prisons had failed to adequately respond to medical emergencies, contributing to 166 prisoner deaths. The Department of Justice recently found that people held in Georgia state prisons had experienced "horrific and inhuman conditions" stemming from what the DOJ called "complete indifference" by the institutions. "Inmates are maimed and tortured," the department wrote, "relegated to an existence of fear, filth and not so benign neglect."

Some years ago, an oversight monitor found that California prisons' system for disciplining officers accused of excessive force was "broken to the core."

For prisoners inside these systems, the courts are often the only backstop left.

But in the 1980s and 1990s, as the nation's prison population exploded, a new law and a series of revised legal standards radically restricted the ability of prisoners to prevail in Eighth Amendment lawsuits.

The 1996 Prison Litigation Reform Act, passed with robust bipartisan support, effectively carved out a separate and unequal system for prisoners who seek to file suit.

It required prisoners to complete a prison's internal grievance process before filing a claim in court — and then survive a screening process. After that, their claims faced exacting Supreme Court standards. Claims that guards had used excessive force were now decided under a 1986 standard that granted broad protections to prison staff as long as their actions were not "malicious and sadistic." Claims that prison staff have failed to keep prisoners safe — whether from violence, negligent healthcare, or inhumane conditions of confinement — were now decided under a Supreme Court standard, refined in 1994, which says such failures violate the Constitution only if officials were "deliberately indifferent."

Together, the standards shifted the focus away from the underlying claims of abuse, however extreme, and onto the question of prison officials' intent.

David Fathi, the director of the National Prison Project at the ACLU, said the emphasis on mindset has become "an enormous barrier to justice for incarcerated people." If abuse or neglect exists in prisons, he said, "that should be enough to violate the Eighth Amendment."

"You shouldn't have to go looking for someone who was thinking bad thoughts."

Altogether, said Kathrina Szymborski Wolfkot, a former appellate attorney at the MacArthur Justice Center, these laws and standards have made federal courts "inhospitable places for incarcerated people." Though some attorneys turn to state courts instead, there they face another set of challenges, such as caps on damages for malpractice claims or, in some cases, weak state constitutional protections.

The Department of Justice, the ACLU, and other powerful litigators have sometimes succeeded in winning Eighth Amendment cases that usher in reforms through consent decrees or injunctive orders. But such outcomes are rare. The DOJ has secured consent decrees in just four prison cases over the past decade.

A separate and unequal system

In restricting access to the courts, lawmakers in the 1990s argued that most prisoners filed suits over "frivolous" matters. Yet only a few dozen of the claims in BI's sample were over minor complaints, such as being denied shoes to wear in a dirty shower.

Among cases that prisoners lost, we logged 161 claims that guards had failed to protect a prisoner from being beaten or stabbed, including four fatalities. We identified 42 failed cases alleging untreated cancer, heart disease, HIV, or hepatitis C. We logged 78 claims of untreated mental illness, including eight that ended in suicide. There were 21 claims of sexual assault by prison staff. There were claims of confinement in extreme filth, including exposure to poisonous spiders, black mold, and feces.

The vast majority of prisoners, BI found, are navigating all of this without attorneys, in part because of the PLRA, which prevents attorneys from recovering their full litigation costs.

In the outside world, most civil suits settle — about 73%, one study found. In BI's sample, only 14% of prisoner lawsuits did, sometimes for paltry amounts or no damages at all. One North Carolina prisoner who said guards beat him while he was in restraints settled for $250.

By the time the cases were settled or decided in favor of the plaintiffs, those in charge — the wardens and medical directors — had almost always been dropped as defendants, limiting the ability of those judgments to drive institutional change.

Billions of taxpayer dollars go to corrections contractors, to run everything from food services to healthcare to staffing to data management, and the legal obstacles introduced in the 1980s and '90s have shielded these for-profit companies as well. For example, hundreds of private prison health providers or their employees were named as defendants in BI's sample. Of these cases, 14% settled and plaintiffs prevailed in less than 1%. One law-review article concluded that the low risk of liability had influenced companies' cost-benefit analysis and "leads to dangerous, ineffective healthcare that is shielded from constitutional challenge."

More than one federal judge described prisoner claims as tragic — before going on to cite precedent or the narrow standards in deciding against the plaintiffs. Several issued fiery dissents. One was issued in an August 2019 case filed by a prisoner who was denied a transfer he said was necessary for his safety. "We do not sentence people to be stabbed and beaten," Judge Robin Rosenbaum of the 11th Circuit wrote.

"The Eighth Amendment does not allow prisons to be modern-day settings for Lord of the Flies," she went on. "The Majority Opinion condones this behavior and ensures it will occur again."
