Illinois v. Fisher
The Supreme Court reversed an Illinois appeals court that had thrown out a cocaine possession charge because police destroyed the seized drugs, even though the destruction happened in good faith under routine procedures.
The Court held that its 1988 ruling in Arizona v. Youngblood controls: without proof police acted in bad faith, destroying evidence that could only have possibly helped a defendant does not violate due process, even if the defendant had asked for the evidence in a discovery motion years earlier.
“unless a criminal defendant can show bad faith on the part of the police, failure to preserve potentially useful evidence does not constitute a denial of due process of law.”
The core rule from Youngblood that the Court applies to reverse the lower court.
How it got here: An Illinois trial court denied dismissal and convicted the defendant; the Illinois Appellate Court reversed on due process grounds; the state sought Supreme Court review.
The Case in Depth
What happened
Chicago police arrested a man in 1988 after seeing him try to hide a bag of white powder later confirmed as cocaine. He requested all evidence in discovery, was released on bond, then fled and became a fugitive for over a decade. When he was finally caught in 1999, the state revived the charge, but by then police had already destroyed the cocaine following standard procedures.
The question before the Court
If police destroy drug evidence in good faith years after a defendant asked to see it, must the charges be thrown out?
Why it matters
Police departments that destroy evidence under routine retention schedules, even years after a defendant requests it in discovery, generally will not face automatic dismissal of charges unless the defendant can show the police acted in bad faith. This preserves law enforcement's ability to manage evidence storage without an automatic due-process penalty tied merely to a pending discovery request.
What changes now
The case is sent back to the Illinois courts for further proceedings consistent with the Supreme Court's reversal. Justice Stevens noted that the appellate court's ruling could still be reinstated on remand because it also rested on an independent state-law holding in People v. Newberry, meaning the ultimate outcome for the defendant was not necessarily settled by this decision alone.
What this does not decide
The Court did not decide whether losing evidence that is truly critical to a defense could ever violate due process without bad faith — Justice Stevens noted he still believes such cases might exist. The ruling also does not disturb Illinois's separate, non-constitutional discovery-sanction rules that the state courts could still apply on remand.
Concurrences and dissents
Concurrence — Justice Stevens
“there may well be cases in which the defendant is unable to prove that the State acted in bad faith but in which the loss or destruction of evidence is nonetheless so critical to the defense as to make a criminal trial fundamentally unfair.”Stevens' longstanding concern that the bad-faith rule might not cover every unfair case.
Justice Stevens agreed with the outcome but noted he still believes, as he did in Youngblood itself, that some cases could exist where lost evidence is so critical to the defense that a trial becomes fundamentally unfair even without proof of police bad faith — though he agreed this is not such a case. He also suggested the Court should not have taken the case at all, since the Illinois ruling had limited value and might be reinstated on remand based on an independent state-law ground.
How the Court got there
The legal reasoning, step by step
- The Court distinguished two lines of due-process cases: when the government withholds evidence that is clearly exculpatory, bad faith is irrelevant and a violation occurs automatically (the rule from Brady v. Maryland and United States v. Agurs); but when evidence is merely 'potentially useful' — meaning testing might have helped the defendant but there's no way to know — due process is violated only if the defendant proves police acted in bad faith (the rule from Arizona v. Youngblood).
- The Court classified the destroyed cocaine as merely 'potentially useful' evidence, since at most a fifth chemical test might have exonerated the defendant, whereas four earlier tests had already confirmed it was cocaine and thus pointed toward guilt, not innocence.
- Because neither the defendant nor the lower court found that police acted in bad faith when they destroyed the substance under routine procedures, the bad-faith showing required by Youngblood was missing.
- The Court rejected the idea that a pending discovery request removes the bad-faith requirement, reasoning that such a rule would gut the very purpose of the bad-faith test, which is to keep police's preservation duties limited to reasonable, clearly justified situations.
- The Court also rejected the theory that Youngblood's bad-faith rule only applies when the evidence is not the defendant's 'only hope for exoneration,' explaining that the Youngblood test turns on whether evidence is merely potentially useful versus clearly exculpatory, not on how central the evidence is to the defense.
