On May 13, 1963, the United States Supreme Court handed down a decision that should have changed American criminal justice forever. In Brady v. Maryland, 373 U.S. 83 (1963), the Court ruled unanimously that suppressing evidence favorable to a defendant — evidence that is material to guilt or punishment — violates the Due Process Clause of the Fourteenth Amendment. It did not matter whether the prosecution acted in good faith. The rule was clear: disclose or violate the Constitution.
Six decades later, the Brady rule is one of the most violated constitutional protections in American law — and one of the least enforced.
The Scale of the Problem
The National Registry of Exonerations, maintained by researchers at the University of Michigan and Michigan State University, has documented more than 3,400 wrongful convictions since 1989. Among those exonerations involving official misconduct — a category covering roughly half of all cases — Brady violations appear in an estimated 40 percent. Prosecutors hid witness statements. They buried lab results. They failed to disclose that the key witness had been promised a deal. They sat on evidence that their star witness had lied before.
These are not mistakes. Under Brady and its progeny — Giglio v. United States, 405 U.S. 150 (1972), and United States v. Bagley, 473 U.S. 667 (1985) — the prosecution's disclosure obligation is affirmative and constitutional. Concealing exculpatory evidence is a willful act against the defendant's most basic rights. And yet the people who do it almost always keep their jobs.
Ted Stevens: A Senator Destroyed by Prosecutorial Misconduct
In October 2008, United States Senator Ted Stevens of Alaska was convicted of seven counts of making false statements for failing to disclose gifts he received from Alaska oil services company VECO Corporation. The conviction, coming just days before his Senate re-election bid, almost certainly cost him his seat. He lost by fewer than 4,000 votes.
But the conviction had been obtained through fraud. Department of Justice prosecutors had withheld notes of an FBI interview with key witness Bill Allen. Those notes showed Allen had given a different account during trial preparation than the one he offered on the stand. The prosecution also concealed that a witness had been provided housing by the government — a benefit the defense was entitled to know about. Federal judge Emmet Sullivan called the misconduct shocking and an unprecedented abuse of the prosecutorial function. He appointed a special prosecutor to investigate the Justice Department's own lawyers.
Attorney General Eric Holder moved to vacate the conviction before Sullivan could act. The charges were dismissed in April 2009. Stevens died in a plane crash sixteen months later — his reputation never fully restored.
The lead prosecutor in the Stevens case was held in civil contempt. She was referred for bar discipline. The result? She was censured by the D.C. Bar — not disbarred, not suspended, not prosecuted. No criminal charges were ever filed against any of the prosecutors involved in one of the most spectacular miscarriages of justice in modern federal law.
Michael Morton: 25 Years for a Crime He Did Not Commit
Michael Morton spent 25 years in a Texas prison for the 1986 murder of his wife, Christine. He did not do it. A neighbor named Mark Alan Norwood did. And Williamson County District Attorney Ken Anderson had evidence pointing that direction from nearly the beginning.
Anderson had suppressed a transcript of a sheriff's deputy's interview with the Mortons' young son, who said he had witnessed the murder and described a stranger — not his father — committing it. Anderson also withheld a neighbor's account of a man parking a green van near the Morton home. Morton had no idea this evidence existed for twenty-five years.
After Morton was exonerated through DNA evidence in 2011, the Innocence Project pursued Anderson with extraordinary tenacity. The result — in a case that legal observers described as nearly unprecedented — was that Anderson, who had since been elevated to a judgeship, was convicted of criminal contempt of court in 2013 for knowingly concealing evidence. He was sentenced to ten days in jail, fined $500, and stripped of his law license.
Ten days. For 25 years of another man's life.
Ken Anderson remains the rare exception. In the overwhelming majority of Brady violation cases, prosecutors face nothing at all.
The Legal Architecture of Impunity
How is this possible? The answer lies in a combination of absolute prosecutorial immunity, narrow judicial remedies, and near-total absence of bar discipline.
In Imbler v. Pachtman, 424 U.S. 409 (1976), the Supreme Court ruled that prosecutors acting within the scope of their duties — including their conduct at trial — have absolute immunity from civil lawsuits. You cannot sue a prosecutor for maliciously pursuing a wrongful conviction. The decision was grounded in concerns about prosecutorial independence, but its practical effect has been to eliminate one of the few mechanisms that might otherwise deter misconduct.
Then came Connick v. Thompson, 563 U.S. 51 (2011), a 5-4 decision that essentially immunized district attorney offices from institutional liability for Brady violations. John Thompson had spent 14 years on Louisiana's death row after prosecutors suppressed blood evidence that would have cleared him. He was exonerated and sued the Orleans Parish DA's office. Justice Clarence Thomas, writing for the majority, held that a single Brady violation — even one causing a near-execution — was insufficient to establish the pattern of conduct necessary to hold a DA's office liable under 42 U.S.C. § 1983. Four justices dissented forcefully. Justice Ruth Bader Ginsburg called the majority's reasoning untethered from the realities of criminal prosecution.
Bar discipline has been the last remaining option — and it barely functions. A 2010 study by the Northern California Innocence Project examined 707 cases of Brady violations identified by courts from 1997 to 2009. In only one case did a prosecutor face bar discipline. One case out of 707.
The Structural Incentive Problem
Why do prosecutors suppress evidence? In part because it works, and in part because the incentive structure of American prosecution rewards winning over justice. In most jurisdictions, district attorneys are elected officials. Conviction rates matter to their political survival. Prosecutors who win cases advance; those whose cases collapse on Brady grounds do not. The system is not designed to surface wrongful convictions — it is designed to prevent their discovery.
Add to this the doctrine of qualified immunity for investigators, the over-reliance on jailhouse informants whose compensation arrangements are routinely hidden, and the cultural insularity of prosecution offices, and you have a system structurally optimized for misconduct without accountability.
A Call for Real Accountability
Brady violations are not technical errors — they are constitutional crimes against the people prosecutors are sworn to protect. Every suppressed lab report, every hidden witness deal, every buried interview note represents a human being whose freedom was stolen by the very system designed to protect it. Congress and state legislatures must enact mandatory open-file discovery rules. State bars must create dedicated prosecutorial misconduct panels with real disciplinary authority and public reporting requirements. Absolute prosecutorial immunity must be curtailed so that victims of misconduct can seek meaningful redress. And prosecutors who commit Brady violations must be named publicly, investigated independently, and where the evidence warrants it, prosecuted. The badge does not make you above the law — it makes your obligation to obey it more sacred, not less.
