Should criminal law recognise omissions liability for knowing presence at a sexual assault? Compare continental duty-to-rescue provisions with the common-law tradition.
Suppose a person is present in a room where a sexual assault is taking place. He does not participate, encourage or assist. He knows what is happening and could intervene or summon help at no risk to himself. He does nothing. Has he committed a crime? In most common-law jurisdictions, the answer is no. In many continental systems, the answer is yes. The divergence reflects deep differences in how the two traditions understand the relationship between criminal law, liberty and solidarity. The question is which approach is better, and specifically whether knowing presence at a sexual assault should ground omissions liability.
The common-law position
The common law has no general duty to rescue. Liability for omissions arises only where a duty exists independently: from a special relationship (parent and child), from voluntary assumption of care (R v Stone and Dobinson, 1977), from contract or office, or from having created the danger (R v Miller, 1983).
Mere presence at a crime is also not enough for accessorial liability. In R v Coney (1882), spectators at an illegal prize fight were not guilty merely by being there. Most directly relevant, in R v Clarkson (1971), soldiers who entered a room where a woman was being raped and remained watching were not guilty as accessories, because there was no proof that their presence was intended to encourage, or did encourage, the principals. Presence becomes complicity only when accompanied by intentional encouragement or assistance. Following R v Jogee (2016), the mental element for accessorial liability requires intention to assist or encourage.
The common-law position therefore leaves a knowing, non-participating bystander outside the criminal law, however callous his inaction.
Continental duty-to-rescue provisions
Many civil-law systems take a different approach. Article 223-6 of the French Code pénal penalises anyone who, able without risk to himself or third parties to prevent by immediate action a crime or offence against bodily integrity, deliberately abstains from doing so, and anyone who deliberately fails to give assistance to a person in danger. Section 323c of the German Strafgesetzbuch penalises failure to render assistance in accidents, common danger or emergency where assistance is required and reasonable. Penalties are substantial in France and more modest in Germany.
These provisions reflect a conception of criminal law as protecting not only negative liberties but also a minimum of social solidarity. They do not make bystanders accessories to the principal crime; they create a distinct, lesser offence of failing to act.
Arguments for recognising liability
First, the moral wrong is serious and clear. A person who watches a sexual assault and does nothing, when he could easily intervene or call for help, fails in a basic duty owed to another person. Joel Feinberg argued that such failures can be harms in the relevant sense, and fall within the harm principle.
Second, the common-law position produces outcomes many find intolerable. The Clarkson result, and the public reaction to the 1983 Big Dan’s case in Massachusetts, which led to state legislation requiring certain witnesses to report violent crimes, illustrate the gap.
Third, knowing presence at a sexual assault is a narrow and well-defined category. A provision limited to it avoids the line-drawing problems of a general duty to rescue.
Arguments against
First, the liberty objection: positive duties are more intrusive than negative ones, and the criminal law should be reluctant to conscript citizens.
Second, the problem of fear. Bystanders at group violence may reasonably fear for their own safety. Continental provisions address this by limiting the duty to action without risk, but assessing risk after the fact is difficult.
Third, evidential difficulties: proving knowledge and capacity to act in chaotic, intoxicated settings is hard, and prosecutions may be arbitrary.
Fourth, the risk of displacement: prosecutors may charge bystanders with the lesser offence rather than pursuing harder cases against participants.
A proposal
The most defensible position recognises a narrow statutory offence: knowingly being present at a sexual assault and failing to take reasonable steps, without risk to oneself, to prevent it or summon assistance. This preserves the common law’s distinction between accessories and bystanders, while closing the gap Clarkson exposed.
Whether such an offence should extend to remote knowledge, such as receiving messages in a group chat, is a further question. The rationale, capacity to prevent serious harm at no risk, applies; but the evidential problems multiply. A cautious first step would confine the offence to physical presence.
