## Facts

- A man and a woman, not married to each other, were indicted for conspiring to transport the woman across state lines for sexual intercourse between them.
- The alleged substantive offense was a violation of § 2 of the Mann Act, which penalized those who transport, cause to transport, or aid or assist in transporting a woman in interstate commerce for prostitution, debauchery, or “any other immoral purpose.”
- At a bench trial, evidence permitted findings that the couple engaged in illicit sexual relations during each charged journey.
- The man purchased railway tickets for both parties for at least one trip.
- Before tickets were purchased for each trip, the woman consented in advance, traveled voluntarily, and did so for the specified immoral purpose.
- Although the indictment alleged conspiracy “with others not named,” the record contained no evidence of any conspirator beyond the two defendants.

## Issues

1. Whether a woman who is the willing object of interstate transportation for an immoral purpose, and who does nothing more than consent, commits the substantive offense under § 2 of the Mann Act.
2. Whether such a woman, by mere acquiescence in the transportation, can be guilty of conspiracy to violate § 2, and whether the man can be convicted of conspiracy when no other conspirator is shown.

## Decision

- The Supreme Court reversed the conspiracy convictions.
- The Court held that a woman who is the willing object of transportation, and who does not aid or assist beyond consent, is not guilty of the substantive § 2 offense.
- The Court held that a woman’s mere acquiescence in being transported for immoral conduct with the transporter does not make her guilty of conspiring to commit the transporter’s § 2 offense.
- Because the only alleged conspirators proved were the man and the woman, and the woman was not punishable for mere consent under the statutory scheme, the conspiracy count failed for lack of a culpable agreement with another liable participant.
- The Court distinguished earlier precedent as allowing the conceptual possibility of a woman’s conspiracy liability only where her conduct goes beyond consent and amounts to active assistance.

## Legal Principles

- When a criminal statute’s structure and targets indicate a legislative choice not to punish a participant for conduct consisting only of consent or acquiescence, courts should not use the general conspiracy statute to impose liability on that participant for that same conduct.
- Under § 2 of the Mann Act, liability attaches to those who transport, cause transportation, or aid/assist transportation; the transported woman’s mere consent, without additional assistance, is not criminalized.
- A conspiracy conviction cannot rest solely on an agreement between a defendant and a person whom Congress, by the substantive statute’s design, left outside punishment for the minimal conduct alleged; additional culpable conspirators or additional culpable acts by the exempted participant are required.

## Conclusion

The Court read the Mann Act as reflecting Congress’s choice not to punish a transported woman for mere consent to her own interstate transportation for an immoral purpose, and it refused to use general conspiracy law to circumvent that choice; without any other proven conspirator, the conspiracy convictions could not stand.
