Lekas v. Illinois

Background

An Illinois defendant was arrested at night without a warrant, held and questioned off and on for about twelve hours, and then confessed after police confronted him with new evidence or another person’s confession. The Illinois appellate court ruled that that confrontation was enough to purge the taint of the alleged illegal arrest. The Supreme Court denied review of that decision, though one Justice wrote a dissent urging the Court to take the case because state courts are split on the issue.

Reasoning

The central question is whether showing a detained person new evidence or a co-defendant’s confession can break the link between an allegedly illegal arrest and a later confession. The dissenting Justice explained that earlier Supreme Court rulings have said formal release from custody or presentation to a neutral magistrate can purge such taint, but the Court has not held that mere confrontation with new evidence does the same. The dissent noted differences among state courts and pointed out there was time to bring the detainee before a magistrate during the twelve-hour period.

Real world impact

Because the Supreme Court declined review, the Illinois appellate ruling stands for now and conflicting state decisions remain unresolved. That leaves police, prosecutors, defense lawyers, and courts operating under different rules in different states about whether confessions obtained after prolonged, warrantless detention are admissible. This was not a final, nationwide ruling on the constitutional question and could be reconsidered later.

Dissents or concurrances

Justice White dissented from the denial of review and would have granted the case, emphasizing the split among states and arguing the issue is an important constitutional question that merits the Court’s decision.
