Wharton's Rule

noun | \ ˈhwȯrt-ᵊnz- \ | Whar·ton's Rule

1. : a rule that prohibits the prosecution of two persons for conspiracy to commit a particular offense when the offense in question can only be committed by at least two persons

   Note: Wharton's Rule does not apply when legislative intent is to the contrary (as when the legislation imposes a separate punishment for conspiracy to commit a particular crime).
