## Facts

- The defendant removed a gas meter from a property to steal the money inside.
- The meter was connected to a neighboring house occupied by the defendant’s future mother-in-law, who was asleep at the time.
- Removal of the meter resulted in gas escaping and entering the neighboring house, poisoning and endangering the occupant’s life.
- The defendant was charged under section 23 of the Offences Against the Person Act 1861 with unlawfully and maliciously administering a noxious substance so as to endanger life.
- The core issue related to the defendant's mental state in connection with causing harm via the gas leakage.

## Issues

1. Whether the term "maliciously" in section 23 of the Offences Against the Person Act 1861 requires proof of actual intent to cause harm or whether awareness of risk (recklessness) suffices.
2. Whether the trial judge erred in directing the jury by equating "malicious" with "wicked," thereby potentially misrepresenting the required mental state (_mens rea_).
3. Whether recklessness as a mental state is sufficient for liability under the statutory provision in question.

## Decision

- The Court of Appeal determined the trial judge's direction to the jury was incorrect, specifically the equation of "maliciously" with "wicked."
- The conviction was reversed because the legal standard for "maliciously" was misapplied.
- The court clarified that "maliciously" in this context means either an actual intention to cause harm or recklessness as to whether such harm should occur.
- The court required the jury to be instructed that the defendant must either intend harm or foresee a risk of harm and proceed regardless.
- This subjective definition of recklessness, now known as "Cunningham Recklessness," was thus established.

## Legal Principles

- "Maliciously" requires either actual intent to cause harm or subjective recklessness regarding the risk of harm.
- Recklessness for these purposes involves the defendant's awareness of the risk; it is not sufficient that a reasonable person would have noticed the risk if the defendant did not.
- A subjective approach focuses on the defendant’s actual state of mind at the material time.
- This principle differs from later objective approaches, such as the test in _R v Caldwell_, which was subsequently overturned in _R v G and another_.
- The Court rejected the notion that "wickedness" alone was sufficient to establish liability under the statute.

## Conclusion

R v Cunningham [1957] 2 QB 396 established the subjective standard for recklessness in criminal law, clarifying that "maliciously" involves either intent or conscious appreciation of risk. This decision set a significant precedent for defining criminal culpability, influencing subsequent case law and the development of subjective tests for recklessness.
