In the 1980s and 1990s, a series of Supreme Court decisions and a new law sought to curb "frivolous" prisoner lawsuits and give more deference to prison officials. Together, they changed the legal landscape of the Eighth Amendment — the foundational constitutional protection against "cruel and unusual punishments."

Heavy criticism soon followed — from the American Bar Association, members of Congress, and Supreme Court justices themselves. Ted Kennedy, then the senior senator from Massachusetts, described one critical measure, the 1996 Prison Litigation Reform Act, as "a far-reaching effort to strip federal courts of the authority to remedy unconstitutional prison conditions."

In successive decades, judges and legal scholars have continued to argue that these developments erode protections for the 1.2 million people incarcerated nationwide. Top law-enforcement officials, on the other hand, have argued that prisoners were clogging up the courts with costly, meaningless actions. And federal judges have hesitated to substitute their own judgment for that of correctional personnel on the ground.

Little has been known about how the Supreme Court standards and the 1996 law shaped outcomes for cases alleging Eighth Amendment violations — and how many of the underlying claims dealt with frivolous matters.

Business Insider set out to investigate. Guided by advice from legal scholars including Margo Schlanger, a law professor at the University of Michigan, and attorneys who have argued Eighth Amendment cases, BI built and analyzed an original database of 1,488 federal Eighth Amendment lawsuits.

BI found that constitutional protections had been dramatically weakened. Cases settled a third as often as civil-rights suits filed by nonprisoners. And plaintiffs won their cases less than 1% of the time.

Here's how we arrived at our findings.

We started with cases in appellate courts

BI sampled lawsuits using Westlaw, a legal-research platform, searching for opinions that cite one of the two Supreme Court standards that now guide how federal courts evaluate Eighth Amendment claims. While Westlaw is one of the most complete databases of legal filings, it is, like the others, not completely comprehensive.

Claims that allege excessive force are governed by a standard called "malicious and sadistic," so to sample those claims BI searched Westlaw for opinions that mentioned the standard and cited one of the Supreme Court's precedent-setting decisions, Whitley v. Albers or Hudson v. McMillian.

Cases alleging constitutionally inadequate healthcare, a failure to protect, or inadequate conditions of confinement are governed by the "deliberate indifference" standard; to sample those claims, BI searched Westlaw for opinions that mentioned the standard and cited Farmer v. Brennan, Wilson v. Seiter, or the earlier Estelle v. Gamble, the relevant Supreme Court precedent-setting cases.

Because so few Eighth Amendment cases make it to the appeals stage, we were able to pull all opinions that fit these parameters over the course of five years — from 2018 to 2022 — spanning two presidential administrations and the COVID-19 pandemic, which affected prisons and courts nationwide.

Then we sampled cases at the district courts

A great many cases filed in district court never reach the appeals courts. In consultation with constitutional scholars, we pulled a sample of district-level cases to understand how Eighth Amendment cases founder earlier in the process. For these, we pulled all cases with judicial decisions filed in the third quarter of 2022 that fit the same search parameters.

Our district sample captured many more cases that failed under mechanisms imposed by the PLRA.

Together, our samples spanned cases from every circuit in the United States filed by prisoners held in hundreds of US prisons in 47 states, Washington, DC, and Puerto Rico. They are likely not comprehensive. If a case file did not mention the Supreme Court standards or the precedent-setting cases — as when a prisoner without counsel lacked knowledge of the law and the case was dismissed on technical grounds at prescreening — our search would not have captured that case. The impact of the PLRA may be greater than our dataset indicates.

About one in 10 cases contained additional claims unrelated to the Eighth Amendment, including claims filed under the First Amendment or the Americans with Disabilities Act. We tracked only the outcomes of their Eighth Amendment claims.

The sample is dominated by suits filed by people while they were incarcerated but also includes cases filed by formerly incarcerated people or their surviving families. BI excluded cases unrelated to incarceration and those pertaining to pretrial detainees. We excluded any case from our district sample that also appeared in the circuit sample. We also excluded cases that had not reached a final disposition, including subsequent appeals, by September 1, 2024.

Our data analysis

A team of researchers read federal court filings associated with each case and logged details in 59 variables including plaintiff names and incarceration status; the claim category and standard applied; defendant names, roles, and employers; alleged harm suffered, such as broken bone, amputation, or death; whether defendants asserted an affirmative defense, such as qualified immunity; whether the plaintiff had counsel; and judge and court names. If a plaintiff had a lawyer at any point during their case, we logged them as having legal representation.

Researchers assigned each case a final disposition category based on the standard or procedural mechanism under which the case was ultimately decided. BI counted all cases that failed under any mechanism of the PRLA — whether they were dismissed at screening, or were struck because prisoners failed to exhaust the prison's grievance process before filing suit, or fell short of any other of the law's requirements — as having failed under the PLRA. This tally included cases in which a judge granted a plaintiff leave to amend. If the plaintiff filed an amended complaint, we logged the case according to its final resolution.

When defendants voluntarily withdrew their cases for reasons clearly unrelated to reaching a settlement; died without a family member or estate to continue their case; or otherwise failed to respond to a court order resulting in dismissal, BI counted these cases as abandoned or withdrawn.

BI's sample included 86 cases with claims governed under both the "malicious and sadistic" and "deliberate indifference" standards. For those, we analyzed the case on both standards, recorded each claim's disposition, and assigned a final disposition category to the case based on the longest surviving claim. For example, if a judge dismissed a plaintiff's excessive-force claim but allowed the plaintiff's claim of inadequate medical care to go to a jury trial, we counted the case outcome under the "deliberate indifference" standard.

In 12 cases, judges granted summary judgment to claims governed by both standards in a single order. Ten of these cases alleged excessive force and alleged inadequate medical care for the injuries they said resulted; two claimed both excessive force and inadequate conditions of confinement. We assigned all these cases as having lost on the "malicious and sadistic" standard since the claims centered on an excessive-force complaint.

The sample includes 28 cases in which a jury found in favor of the defendants. BI counted these as cases in which the plaintiffs lost on the relevant standard.

BI counted cases as having failed on qualified immunity, the Supreme Court doctrine that can shield public officials from civil liability, only when that standard was decisive in the dismissal of a plaintiff's claim. Another Supreme Court precedent, known as Bivens, governs cases filed against federal officials; we tallied a case as a Bivens failure only when a judge dismissed a claim solely because it had not met Bivens standards.

All cases were recorded as having reached a settlement when the settlement was clearly stipulated in the docket or when the defendant and the plaintiff submitted a joint motion for dismissal pursuant to an out-of-court settlement agreement. To identify damages paid, BI reviewed the docket for disclosed settlement amounts and supplemented this research with news reports and public announcements.

BI counted two categories of cases as plaintiff wins: cases in which the plaintiff won at jury trial and cases in which judges made decisions in favor of the plaintiff — whether for damages or for injunctive relief.

To supplement and contextualize our analysis of the 1,488 lawsuits, containing tens of thousands of pages of court records, we reviewed hundreds of pages of training materials obtained through public-records requests from 37 states, as well as medical records, incident reports, and surveillance footage obtained through records requests and court filings. We reviewed scholarly literature on the Eighth Amendment; read Supreme Court decisions, dissents, and archives; and reviewed archived congressional debates. And we interviewed more than 170 people, including prisoners and their families, attorneys and legal scholars, correctional staff and prison healthcare providers, policymakers and law-enforcement officials, and current and former federal judges.

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."
