Regina v. Faulkner (1877) 13 Cox C.C. 550 (Court for Crown Cases Reserved, Ireland)
Regina v. Faulkner is a foundational case in criminal law on the alignment of mens rea with the actus reus of the charged offense.
Whether the intent to commit theft can supply the mens rea ("maliciously") required for arson, or whether the prosecution must prove that the defendant intended to burn the ship or foresaw the risk of burning.
For offenses requiring that the act be done "maliciously," the prosecution must prove that the defendant intended the particular harmful result or consciously foresaw the risk that such harm would likely occur and proceeded regardless (recklessness). The mental state for one offense cannot be transferred to satisfy the mens rea of a different offense resulting from the same course of conduct.
No. The mens rea required for arson cannot be supplied by the defendant's intent to steal. The jury must be instructed to convict only if the defendant intended to burn the ship or foresaw the likelihood of burning; otherwise, he is not guilty of malicious arson. The conviction was set aside and a new trial ordered with proper instructions.
Faulkner is a leading case limiting transferred intent and reinforcing that mens rea must correspond to the harm specified by the offense. It is frequently taught to distinguish cross-victim transferred malice (e.g., assault where the wrong person is hit) from cross-offense transfer, which Faulkner rejects. It also clarifies that recklessness—understood as foresight of a likely risk—is sufficient for "maliciously" in arson, shaping proper jury directions in consequence-based crimes and anchoring modern discussions of the correspondence principle in mens rea doctrine.
