Facts
- A rape occurred around 6:00 p.m. on April 7, 1954, in the basement of an apartment building where the victim sought help from the janitor’s household, which included 19-year-old Andrew R. Mallory.
- A masked assailant attacked the victim shortly after Mallory assisted with a hose; the victim described features resembling Mallory and relatives living there.
- Mallory and a nephew left the premises soon after the crime.
- Mallory was arrested the next afternoon (about 2:00–2:30 p.m.) and taken to police headquarters.
- At headquarters, multiple officers questioned him for roughly 30–45 minutes; he denied guilt.
- Around 4:00 p.m., officers sought lie-detector testing; Mallory agreed and waited for hours at headquarters while the operator was located.
- Mallory’s polygraph-related questioning began after 8:00 p.m.; officers testified he confessed around 9:30 p.m.
- Mallory was held near available committing magistrates but was not promptly taken before one; police attempted to arrange presentment only after the confession, and he was not presented until the following morning.
- Mallory was not advised of a right to counsel, a prompt preliminary examination before a magistrate, or a right to remain silent and that statements could be used against him.
- The trial court admitted the confession over objection; Mallory was convicted of rape and sentenced to death; the conviction was affirmed on appeal.
Issues
- Whether police violated Federal Rule of Criminal Procedure 5(a) by failing to bring Mallory before a committing magistrate “without unnecessary delay.”
- Whether a confession obtained during an unlawful delay in presentment must be excluded in a federal prosecution, apart from ordinary voluntariness analysis.
Decision
- The Supreme Court reversed and remanded.
- The Court held that Mallory was not taken before a committing magistrate without unnecessary delay as Rule 5(a) requires.
- Because the confession was obtained during a period of unlawful delay used for custodial interrogation, the confession was inadmissible.
Legal Principles
- Federal Rule of Criminal Procedure 5(a) requires that an arrested person be brought before a committing magistrate “without unnecessary delay.”
- When police use pre-presentment detention to interrogate a suspect instead of promptly initiating judicial supervision, the delay is “unnecessary” under Rule 5(a).
- Under the McNabb–Mallory doctrine (rooted in supervisory authority over federal criminal procedure), a confession obtained during an unlawful delay in presentment is inadmissible in federal court even if not shown to be coercive under traditional due process standards.
- Prompt presentment serves protective functions by shifting control from police to a magistrate and ensuring early judicial warnings and procedures.
Conclusion
The Court ruled that Rule 5(a) forbids using delayed presentment to facilitate stationhouse interrogation and required exclusion of Mallory’s confession because it was obtained during unnecessary delay before a magistrate, necessitating reversal of his conviction.
