Justice Frankfurter agreed that Chicago itself was not liable under § 1983, but otherwise dissented. He accepted that the complaint alleged grave constitutional wrongs and that § 1983 creates a civil remedy without requiring the specific intent demanded by the related criminal statute. His disagreement concerned whether the officers' unauthorized conduct was taken “under color of” state law.
In his view, the statute's text and Reconstruction-era history distinguished conduct authorized by state statute, ordinance, regulation, custom, or usage from an officer's lawless departure from state law. Section 1983 was intended to provide federal redress when the State, through law or settled official practice, sanctioned or shielded constitutional violations—not to federalize every ordinary state tort or crime committed by an official.
Frankfurter argued that Classic, Screws, and Williams did not deserve decisive stare decisis weight because they had not carefully examined the relevant legislative history. He viewed Classic in particular as having treated the separate concepts of state action and action under color of state law as if they were the same question.
The Reconstruction Congress, he reasoned, was responding to systematic state failures to protect Black citizens and Union supporters, including entrenched practices under which state officials or institutions effectively denied redress. That historical setting supported a remedy for official conduct authorized by law or sustained as a settled custom, but not isolated misconduct that state law itself prohibited and state courts could redress.
Expanding § 1983 to cover every lawless act by a state official would, in Frankfurter's view, improperly shift broad areas of tort and criminal administration from state to federal courts. The need for stronger remedies against police abuse was real, but he believed any such expansion had to come from Congress rather than from reinterpreting an 1871 statute.
Frankfurter concluded that the alleged home invasion was not actionable under § 1983 because it violated Illinois law and was not factually alleged to rest on a state-sanctioned custom or usage. He would, however, have allowed the claim concerning Mr. Monroe's detention to proceed because the complaint specifically alleged a Chicago Police Department custom of holding people for extended periods on “open” charges, incommunicado and without judicial process.
