Brief Fact Summary. A county in Florida allowed prisoners to be held for a substantial amount of time without a hearing, based solely on the decision of a prosecutor.
Synopsis of Rule of Law. “Whatever procedure a State may adopt, it must provide a fair and reliable determination of probable cause as a condition for any significant pretrial restraint of liberty, and this determination must be made by a judicial officer either before or promptly after arrest.”
A probable cause determination does not require the fine resolution of conflicting evidence that a reasonable-doubt or even a preponderance standard demands, and credibility determinations are seldom crucial in deciding whether the evidence supports a reasonable belief in guilt.

Held. “To implement the Fourth Amendment’s protection against unfounded invasions of liberty and privacy, the Court has required that the existence of probable cause be decided by a neutral and detached magistrate whenever possible.” “[T]he Fourth Amendment requires a judicial determination of probable cause as a prerequisite to extended restraint of liberty following arrest.” “At common law it was customary, if not obligatory, for an arrested person to be brought before a justice of the peace shortly after arrest. The justice of the peace would ‘examine’ the prisoner and the witnesses to determine whether there was reason to believe the prisoner had committed a crime. If there was, the suspect would be committed to jail or bailed pending trial. If not, he would be discharged from custody. The initial determination of probable cause also could be reviewed by higher courts on a writ of habeas corpus. This practice furnished the model for criminal procedure in America immediately fo
llowing the adoption of the and there are indications that the Framers of the Bill of Rights regarded it as a model for a ‘reasonable’ seizure.”
Dade County defends “the prosecutor’s decision to file an information is itself a determination of probable cause that furnishes sufficient reason to detain a defendant pending trial.” However, the court recognizes “[a]lthough a conscientious decision that the evidence warrants prosecution affords a measure of protection against unfounded detention, we do not think prosecutorial judgment standing alone meets the requirements of the Fourth Amendment. Indeed, we think the Court’s previous decisions compel disapproval of the Florida procedure.”
“In holding that the prosecutor’s assessment of probable cause is not sufficient alone to justify restraint of liberty pending trial, [the majority does] not imply that the accused is entitled to judicial oversight or review of the decision to prosecute. Instead, we adhere to the Court’s prior holding that a judicial hearing is not prerequisite to prosecution by information. Nor do we retreat from the established rule that illegal arrest or detention does not void a subsequent conviction. Thus, as the Court of Appeals noted below, although a suspect who is presently detained may challenge the probable cause for that confinement, a conviction will not be vacated on the ground that the defendant was detained pending trial without a determination of probable cause.”
Various adversary safeguards “are not essential for the probable cause determination required by the Fourth Amendment. The sole issue is whether there is probable cause for detaining the arrested person pending further proceedings. This issue can be determined reliably without an adversary hearing. The standard is the same as that for arrest. That standard – probable cause to believe the suspect has committed a crime – traditionally has been decided by a magistrate in a nonadversary proceeding on hearsay and written testimony, and the Court has approved these informal modes of proof.”
“The use of an informal procedure is justified not only by the lesser consequences of a probable cause determination but also by the nature of the determination itself. It does not require the fine resolution of conflicting evidence that a reasonable-doubt or even a preponderance standard demands, and credibility determinations are seldom crucial in deciding whether the evidence supports a reasonable belief in guilt. This is not to say that confrontation and cross-examination might not enhance the reliability of probable cause determinations in some cases. In most cases, however, their value would be too slight to justify holding, as a matter of constitutional principle, that these formalities and safeguards designed for trial must also be employed in making the Fourth Amendment determination of probable cause.”
Discussion. This case establishes that “a timely judicial determination of probable cause [i]s a prerequisite to detention.”
