Essay question: "The law of non-fatal offences against the person is a patchwork of common law and statute, incoherent in structure and unprincipled in its allocation of fault." Discuss.
---
Introduction
The proposition captures a widely held view among commentators and reformers. The Offences Against the Person Act 1861 was a consolidating statute, not a codifying one, and its language—"occasioning," "inflicting," "maliciously," "grievous"—reflects nineteenth-century drafting conventions rather than coherent principle. Common assault and battery remain common-law offences, now charged summarily under s 39 Criminal Justice Act 1988. The result is a hierarchy that, as the Law Commission observed in 1993, exhibits "maximum inconvenience with minimum logic." This essay examines three aspects of incoherence—structure, labelling, and fault—before considering whether the criticisms are overstated and what reforms might be justified.
I. Structural incoherence
The ladder of offences is difficult to rationalise. At the base lie assault (causing apprehension of force) and battery (application of force), distinct common-law misdemeanours with identical maximum sentences and overlapping fact patterns. A single punch may constitute both (raising a fist = assault; contact = battery) or just one. Students and practitioners alike struggle to explain why the law maintains the distinction, especially since in practice they are often charged together as "common assault."
The next rung—s 47 assault occasioning actual bodily harm—requires proof of an assault or battery plus causation of ABH. The offence is indistinguishable in mens rea from common assault; only the result elevates it to an either-way offence with five years' maximum. Sections 20 and 18 likewise turn on results (GBH, wounding) but introduce new language: s 20 speaks of "inflicting," s 18 of "causing." For decades, courts debated whether "inflict" required an assault; Burstow [1998] AC 147 held it does not, rendering the textual difference between ss 20 and 18 functionally meaningless. Why Parliament used different verbs is a matter of historical accident, not design. This lack of systematic structure impedes comprehension and invites error.
II. Defective labelling
The principle of fair labelling, articulated by Ashworth and others, holds that offence categories should reflect morally significant distinctions and that conviction labels should correspond to the defendant's culpability. The 1861 Act fails on both counts. "Assault occasioning actual bodily harm" misleadingly suggests that the defendant foresaw ABH, when in fact Savage / Parmenter [1992] 1 AC 699 requires only foresight of unlawful force. A defendant who intended a minor shove, resulting unexpectedly in a broken wrist, is convicted under the same label as one who punched intending to injure. Similarly, s 20 labels a defendant as having "unlawfully and maliciously inflicted grievous bodily harm" even if they foresaw only trivial harm. The label overstates fault and may carry unwarranted stigma.
Moreover, the Act's terminology is opaque. "Grievous" is archaic; "wounding" is technical (requiring a break in both layers of skin: Eisenhower [1984] QB 331) and does not track moral gravity—a pin-prick is a wound, but a severe internal rupture is not. These distinctions are difficult to explain to juries and serve no obvious purpose beyond historical continuity.
III. Fault: constructive liability and the correspondence principle
The most serious charge of incoherence concerns the allocation of fault. Both s 47 and s 20 exemplify constructive liability: the defendant is liable for a harm more serious than they foresaw, provided they had mens rea for a lesser wrong. For s 47, intention or recklessness as to unlawful force suffices, even if ABH was unforeseeable; for s 20, foresight of some harm (however slight) suffices for liability for GBH. This structure violates the correspondence principle—the idea that fault should correspond to the prohibited harm.
Lord Ackner in Savage / Parmenter acknowledged the criticism but held that precedent and statutory language compelled the result. The Law Commission has repeatedly condemned constructive liability as unprincipled. It is one thing to hold a defendant liable for unforeseen consequences on a causing-harm analysis (as in unlawful-act manslaughter); it is another to label and punish them for an offence defined by reference to that unforeseen harm. The current law conflates causing harm with committing a harm-offence, and in doing so it departs from the subjective fault principles now dominant in English criminal law.
IV. Defences and qualifications
Two counter-arguments deserve consideration. First, J.C. Smith and others have argued that requiring foresight of the precise level of harm would make prosecution unduly difficult. Defendants could escape liability by claiming they foresaw only minor injury. Provided they acted with some culpable state of mind (foresight of unlawful force or some harm), it is not unjust to hold them liable for greater harm that materialises. This pragmatic view privileges deterrence and ease of proof over theoretical consistency.
Second, one might argue that the law's flexibility—its retention of common-law offences and broad statutory categories—enables it to adapt to new harms (e.g., psychological injury in Ireland / Burstow) without constant legislative amendment. A more rigid code might ossify and prove less responsive.
These arguments carry some weight but do not, in my view, rebut the charge of incoherence. Ease of prosecution is not a sufficient justification for violating correspondence, especially where fair labelling and proportionate punishment are at stake. And flexibility can be achieved within a rational structure, as civilian codes demonstrate.
V. Prospects for reform
The Law Commission's 1993 draft Bill proposed a clean hierarchy: intentional serious injury, reckless serious injury, intentional or reckless injury, and assault. Each offence would require mens rea corresponding to the harm. The scheme would abolish archaic language, eliminate the common-law/statute divide, and restore correspondence. Reform along these lines would address the principal defects identified in this essay. Yet successive governments have declined to act, perhaps because non-fatal offences, unlike homicide, lack a high political profile. Ashworth has suggested that piecemeal amendment—removing constructive liability from s 47, clarifying "inflict," modernising terminology—might be more achievable, though less satisfying.
Conclusion
The proposition is substantially correct. The law of non-fatal offences combines common law and Victorian statute in a way that is structurally untidy, terminologically obscure, and unprincipled in its allocation of fault. The retention of constructive liability in ss 47 and 20 is the gravest flaw, violating both correspondence and fair labelling. While pragmatic arguments can be mounted in defence of the status quo, they do not render the law coherent. The case for comprehensive reform remains strong; whether Parliament will act is another matter. Until it does, students, practitioners, and courts must navigate a body of law that, in Glanville Williams's apt phrase, offers maximum inconvenience with minimum logic.
