Incident Summary & Facts

In December 1980, the Rhode Island State Police were running a court-authorized wiretap on the phone of Paul Driscoll, an acquaintance of the respondents’ daughter. On December 20, police intercepted a call from a man calling himself “Dr. Shogun,” logged as: “caller says I can’t believe I was token [sic] in front of Jimmy Briggs — caller states he passed it to Louisa . . . Paul says Nancy was sitting in his lap rolling her thing.” Trooper Edward Malley, who ran the investigation, read “toking” and “rolling her thing” as references to marijuana. He concluded from another call that day that the party had been at the respondents’ home. Based on these two calls, he prepared felony complaints charging James and Louisa Briggs with conspiracy to possess marijuana, along with affidavits describing the calls and his interpretation. In February 1981, a state district judge signed arrest warrants for the respondents and 20 others. Justice Powell’s separate opinion noted that the call log said only that the caller “passed it to Louisa,” and that the cigarette may have gone to a different Louisa.

The respondents, described as prominent members of their community, were arrested at home shortly before 6:00 a.m. on March 19, 1981, then booked, held for several hours, arraigned, and released. Their arrests were publicized. The charges were dropped when the grand jury returned no indictment. They sued Malley under § 1983 for Fourth and Fourteenth Amendment violations. At the close of the plaintiffs’ evidence, the district court directed a verdict for Malley, reasoning mainly that the judge’s issuance of the warrants broke the causal chain. The First Circuit reversed.

The case did not involve a use-of-force encounter. It concerns the immunity of an officer who applies for an arrest warrant.

Whether a police officer sued under § 1983 for causing an unconstitutional arrest by submitting a complaint and affidavit that failed to establish probable cause is entitled to absolute immunity, or to qualified immunity only. If qualified, the further question was whether a judge’s issuance of the warrant makes the officer’s application per se objectively reasonable.

The Holding

An officer who applies for an arrest warrant gets only qualified immunity, not absolute immunity. That immunity is lost where “the warrant application is so lacking in indicia of probable cause as to render official belief in its existence unreasonable.” The First Circuit’s judgment was affirmed and the case remanded.

The Court’s Analysis:

  • No common-law absolute immunity. In 1871, a complaining witness who procured an arrest warrant maliciously and without probable cause could be held liable. For executive officers, “qualified immunity represents the norm.”
  • Qualified immunity is ample protection. It shields “all but the plainly incompetent or those who knowingly violate the law.” Officers are not immune “if, on an objective basis, it is obvious that no reasonably competent officer would have concluded that a warrant should issue; but if officers of reasonable competence could disagree on this issue, immunity should be recognized.”
  • The prosecutor analogy fails. Applying for a warrant is further removed from “the judicial phase of the criminal process” than seeking an indictment. Qualified immunity encourages officers to reflect before applying, which reduces premature arrests.
  • The Leon standard applies. The same objective-reasonableness test used for good-faith reliance on warrants in suppression hearings (United States v. Leon) governs: “whether a reasonably well-trained officer in petitioner’s position would have known that his affidavit failed to establish probable cause and that he should not have applied for the warrant.”
  • A judge’s approval is not a safe harbor. Because “ours is not an ideal system,” a magistrate under docket pressure may err, and the officer “cannot excuse his own default by pointing to the greater incompetence of the magistrate.” The Court also rejected the “no causation” theory: § 1983 makes a person responsible for the natural consequences of his actions. Whether Malley actually acted reasonably was left for remand.
  • Partial dissent (Powell, J., joined by Rehnquist, J.): The magistrate’s probable-cause finding deserves “substantial evidentiary weight,” a reasonably competent officer could have believed the wiretap logs supplied probable cause, and Malley should have been held immune.
