Fagan v Commissioner of Police of the Metropolis

Factual and Procedural Background

The Appellant was convicted by a magistrates' court of assaulting a police constable in the execution of his duty on August 31, 1967. The incident occurred when the Appellant was reversing a motor car on a public road and was directed by the constable to park closer to the kerb. The Appellant initially stopped the car with the offside wheel on the constable's left foot. Upon the constable's repeated requests to remove the wheel, the Appellant reluctantly complied after a delay. The Appellant appealed to the quarter sessions, which dismissed the appeal. The present appeal arises by way of case stated from the quarter sessions' decision, focusing solely on whether the facts proved legally amount to an assault.

Legal Issues Presented

1. Whether the prosecution proved facts which in law constituted an assault.
2. Whether an act that initially was accidental but continued with knowledge and intention can amount to an assault.
3. Whether a continuing act can establish the concurrence of actus reus and mens rea necessary for assault.
4. Whether an omission to remove the wheel, following the initial contact, can constitute an assault.

Arguments of the Parties

Appellant's Arguments

• The initial contact of the car wheel on the constable's foot was accidental and thus not an assault.
• After the initial contact, there was no actus reus but only an omission to remove the wheel promptly.
• An omission cannot constitute an assault, nor can it supply the mens rea necessary to convert an accidental act into a criminal assault.

Respondent's Arguments

• The actus reus began with the initial contact and continued until the wheel was removed.
• The Appellant formed the necessary mens rea during this continuing act by knowingly and provocatively allowing the wheel to remain on the foot.
• Alternatively, in certain situations, an omission to act in breach of a duty could amount to an assault, though this point was not conclusively addressed.

Court's Reasoning and Analysis

The court examined whether the appellant's act of placing the car wheel on the constable's foot was a completed act or a continuing act. It held that an assault requires both actus reus (an act) and mens rea (intention or recklessness) to be present simultaneously. The court reasoned that the initial contact might have been accidental, but the appellant's subsequent conduct—remaining seated in the car, switching off the ignition, maintaining the wheel on the foot, and using words indicating an intention to keep the wheel there—constituted a continuing act. The mens rea was formed during this continuing act, thereby fulfilling the requirements for assault. The court rejected the argument that mere omission could constitute assault, emphasizing that the appellant's conduct was active rather than passive. A dissenting judge agreed on the legal principles but concluded that the appellant's conduct did not amount to an assault, viewing the wheel as resting by its own weight and the appellant's failure to move the car as an omission rather than an act.

Holding and Implications

The court DISMISSED the appeal, upholding the conviction for assault. The decision confirms that a continuing act can satisfy the concurrence of actus reus and mens rea necessary for assault, even if the initial contact was accidental. The ruling clarifies that the mens rea can be superimposed on an ongoing act and that maintaining an unlawful physical contact with intention constitutes a battery and thus an assault. No new precedent was established beyond the application of existing principles to the facts. The direct effect is the affirmation of the appellant's conviction.
