Fagan v Metropolitan Police Commissioner

Facts

The defendant was directed by a police officer to park his car. He accidentally drove onto the officer foot. When the officer told him to get off, the defendant refused, saying he could wait, and kept the car on the foot for a short time before reversing off. The defendant was charged with assaulting a police officer in the execution of his duty.

History

The defendant was convicted of assaulting a police officer in the execution of his duty, and his appeal to London Quarter Sessions was dismissed. He appealed by case stated to the Divisional Court, arguing that driving onto the foot was an act without mens rea and that his later failure to move the car was a mere omission, so that there was no coincidence of actus reus and mens rea.

Issue

Whether an omission to act can form the actus reus of battery where the initial contact was accidental, and whether the actus reus of battery can be treated as a continuing act for the purpose of coincidence with mens rea.

Held

Appeal dismissed; conviction upheld.

Ratio

• The actus reus of battery can be a continuing act; where a defendant creates a dangerous situation and fails to take steps to end it, the omission can form part of a continuing actus reus that coincides with the mens rea formed during the continuation.

Key reasoning

• The initial act of driving onto the foot was accidental and lacked mens rea, so it could not alone constitute battery.
• The defendant's subsequent refusal to move the car created a continuing actus reus, as the application of force persisted.
• The mens rea for battery, intention or recklessness as to the application of unlawful force, arose when the defendant became aware that the car was on the foot and chose to keep it there.
• The coincidence of the continuing actus reus and the mens rea during the period of refusal satisfied the requirements for battery.

Where it fits in the module

This case is foundational for Topic 1 (Basic Principles of Criminal Law) as it illustrates the actus reus requirement, the treatment of an apparent omission as part of a continuing act, and the principle of coincidence of actus reus and mens rea. It is followed by later cases such as Miller (1983), which dealt with a duty to act, and DPP v Santana-Bermudez (2003) on omissions in assault, and informs the debate on whether omissions can ever constitute the actus reus without a statutory duty.

Criticisms

• The continuing act doctrine blurs the distinction between acts and omissions, potentially expanding criminal liability beyond clear legislative intent.
• It is conceptually strained to treat a passive failure to move as a 'continuing act' rather than a true omission requiring a duty of care.
• The approach may undermine the requirement that actus reus be a voluntary act, since the initial act was involuntary and the subsequent conduct was an omission.
• Later cases have struggled to define the limits of when a situation becomes a 'continuing act' versus a mere omission, creating uncertainty.
