People v. Foster, 99 Ill. 2d 48, 457 N.E.2d 405 (Ill. 1983)

Facts

  • James W. Foster approached John Ragsdale in a bar and suggested “making some money” by robbing an elderly man believed to keep valuables.
  • The next day, Foster discussed details of the planned robbery with Ragsdale.
  • Ragsdale decided to feign agreement to gather information, but he did not intend to participate in the robbery.
  • Foster later went to Ragsdale’s home to see if he was “ready to go”; Ragsdale attempted to delay by saying he needed to find another person to help.
  • Ragsdale informed police of the plan, and police later arrested Foster and Ragsdale when they arrived at the intended victim’s residence.
  • A jury convicted Foster of conspiracy to commit robbery under Illinois law; the appellate court reversed, concluding no conspiracy existed because Ragsdale never truly agreed.

Issues

  1. Whether Illinois’s conspiracy statute requires a bilateral agreement (a true agreement of at least two persons) or permits a unilateral theory (conviction when the supposed co-conspirator only feigns agreement).
  2. Whether a conspiracy conviction can stand when the only alleged co-conspirator subjectively lacked intent to join the criminal plan.

Decision

  • The Illinois Supreme Court affirmed the appellate court’s reversal of Foster’s conspiracy conviction.
  • The court held the Illinois conspiracy statute requires an actual agreement of at least two persons.
  • Because Ragsdale only feigned agreement and never intended to participate, no conspiratorial agreement existed as a matter of law.
  • Under Illinois law, conspiracy requires a true agreement between at least two persons who each intend to commit the offense; apparent assent by an informant or decoy is insufficient.
  • Absent clear statutory language adopting unilateral conspiracy, courts presume the legislature retained the traditional bilateral requirement.
  • Ambiguities in penal statutes are construed in favor of the accused, supporting rejection of unilateral conspiracy when legislative intent is unclear.
  • Prior judicial constructions of a statute, coupled with legislative inaction, may support the inference that the legislature accepted the established interpretation.

Conclusion

Illinois’s conspiracy statute imposes a bilateral agreement requirement, so a defendant cannot be convicted of conspiracy when the only alleged partner merely pretended to agree and lacked intent to join the criminal objective.
