Leaving Good Undone: Omissions in English Criminal Law

We know from current case law and statute that omissions may be, and are, punished although “[g]enerally in English criminal law a person is not liable for failing to act … even if another person’s life is in danger.” (1) There is a substantial exception from this rule, and it is generally accepted by both courts and academics: “a defendant is liable if he or she fails to act when under a duty to act.” (2)

However, the word “omission” in itself can be confusing.

What is an omission?

The Oxford English Dictionary currently describes the word “omission” as follows:

1. The non-performance or neglect of an action which one has a moral duty or legal obligation to perform; an instance of this. Recorded earliest in sin of omission
2. a. The action of omitting, leaving out, or not including a person or thing. b. An instance of this; (concr.) a person or thing that has been omitted or passed over. (3)

It is worth noting, especially in the context of this paper, that the first recorded instance of the word in English, around the beginning of the 15th century, defined an omission as “leaving good undone: when men leave the good they should do” and, among other examples, “to do negligently what one was bound by vow to do, or by command …and yielding not a good deed for another if one can.” (4)

The second recorded occurrence of the word, in the pietistic writings of Bishop Richard Pecock, explains the word as above — “leavings of [something] undone”, but also brings the counterpart concept: commissions, “the contrary doings against [one].” (5)

At least to what regards medieval pietistic thinking, an omission (in the meaning 1. above) appears to be considered just as bad as a commission. Given that the word and its counterpart applied to morals, and were associated as concepts with sins, we should not be surprised at the process of transition and correlation from the religious sphere to the judicial, leading to the contrasting pair of omission and act in use to this day.
The omission formulated by Rolle of Hampole is “leaving the good undone.” This presents us with the meaning familiar to law students and practitioners of today: “e.g. ‘failing to…’, usually in the context of an undertaking.” (6)

From a failing to a criminal matter

In his seminal essay on omissions in criminal law, Professor Andrew Ashworth enumerates five possible situations when a duty might be imposed by the courts:

  1. Prior created dangerous act ;
  2. Relationship duties ;
  3. Undertaken duties ;
  4. Duties of ownership or control of property (7) ;
  5. Citizenship duties.

This latter is less encountered in practice in the English context, but is often mentioned in theoretical approaches, especially in the context of “Good Samaritan Laws”. (8)

This point of view is generally held as the current position of the law, although with significant subtractions or additions to it. In Great Debates on Criminal Law (9), Jonathan Herring prefers to omit citizenship duties completely, whereas Smith and Hogan: Criminal Law introduces a new duty, namely that of Dangerous pursuits (10), and then renames (and shortens drastically) ‘Citizenship duties’ as ‘A general duty of rescue’. For clarity, Ashworth’s ‘Undertaken duties’ are also broken into ‘Contract’ and ‘Voluntary undertakings’.

Irrespective of the formulation (the language used and its interpretation being liable to bring further complications), the consensus is that once a duty to act exists, a breach by action or omission is likely to attract sanction.

It would be easy to dismiss further discussion saying that this clarifies the position and matters should always proceed accordingly. This paper starts from the premise that “The law does and should criminalise omissions to act just as much as it criminalises positive acts,” and we shall see now how exactly it does this.

Mustill LJ in Airedale National Health Trust v Bland said that “[t]he English criminal law … draws a sharp distinction between acts and omissions” but he showed his dissatisfaction by adding that “the current state of the law is unsatisfactory both morally and intellectually” and that “[f]or the time being all are agreed that the distinction between acts and omissions exists, and we must give effect to it.” (11)

We thus have an admission at the highest judiciary level that the state of affairs (as of 1993) was in need of reform and the discussion has been ongoing since at least 1985 when the Law Commission proposed a codification of the criminal law (12). In 1987, Professor Glanville Williams expressed his anxiety with regards to the status of omissions in the draft code, believing that “[it] provides too great scope for offences of omission,” (13) and critics have been calling for an overhaul ever since, becoming — to paraphrase a 2011 article by Andrew McGee — increasingly louder, and their words increasingly stronger . (14)

Although there is a general consensus that the law should punish omissions (15), it is not always clear as to what the omission are, in either of the main views on the subject: “the conventional view”, and the “social responsibility view” (16). In both views, the difficulty lies in separating acts from omissions, and deciding to what extent an omission can be said to have a positive effect and so have criminal liability imposed on it. We shall embrace Ashworth’s view that “although there are some clear cases of omission and some clear cases of act, there are many ambiguous cases” (17) in which act and omission — doing and non-doing — overlap, and shall consider things at face value through this perspective.

The philosophical distinction between acts and omissions is arguably too complicated to deal with in this paper at the length and breadth it deserves, and, following Lord Diplock’s example, we shall continue with it as it is. We can take a look instead at the current approach of the courts for the imposition of liability. This includes:

“(i) classification (is the case one of omission or act?); (ii) the scope of liability (is the offence in question one under which conviction can arise for omission?); (iii) the moral bases of liability (on what grounds can the law impose a duty to act?); (iv) issues of causation (how can D’s failure to act result in a proscribed wrong?). (18)

It will be necessary not just to look at some cases through this lens, but also, in order to understand the moral dimension of this approach, to return to the religious medieval man and his example of omission as “leaving good undone.” What else can we consider an omission other than a good left undone in a case like Miller (19), in which the defendant who set a mattress on fire moves to another room in order to sleep, without putting the fire out first? We can even say that Mr Miller, in the words of Rolle (20) “was bound by vow to do” something — in this case the vow being his duty to remedy a dangerous situation he initiated. This point proved to be crucial in his conviction for criminal damages. As a strict liability offence, it became irrelevant that Miller had had no intention to set fire to the house, that there was no mens rea (21). The House of Lords found that it was an “erroneous notion that failure to act cannot give rise to criminal liability in English law.” (22)

A different omission, but with the similar effect of being construed into an act, occurred in DPP v Santana-Bermudez (23); when asked whether he still had “any sharps” on him, a man who was going to be body searched by the police replied that he didn’t, after emptying his pockets. The constable who conducted the search then stuck her finger in a hypodermic needle. The issue at stake was whether the defendant could be guilty of assault by omission. The High Court found that he did not cause the assault by a positive act, but his omission did lead to it.

As an exercise, this is how the courts’ approach, as identified by Elliott and Ormerod, applies to Miller and Santana-Bermudez: (i) an omission was construed as an act; (ii) there was scope for liability; (iii) once the omission was viewed as a culpable act, there was a moral basis for the imposition of a duty to act; and (iv) but for the Defendant’s omission there would have been no damage or assault.

We now have a framework which is applied to future cases, and we might obtain some certainties, but it doesn’t mean that we have solved the bigger questions: (i) what differentiates omissions from an acts?; (ii) and if it is an omission, to which point does the scope for liability extends? As such, Maurice Kay J in Santana-Bermudez seems to share the annoyance shown by Lord Diplock twenty years previously in Miller:

“A great deal of undesirable complexity has bedevilled our criminal law as a result of quasi theological distinctions between acts and omissions.”

Conclusion: What to do next?

Argumentation on omissions in criminal law seems to be under the aegis of the parable of the Good Samaritan (24). Did the men walking past an injured man without helping him have a duty to act? Morally speaking, yes — in Jesus’ parable we are exhorted to love our neighbour.

From a legal point of view, the situation is different. In the words of Lord Diplock in Miller:

“The conduct of the parabolical priest and Levite on the road to Jericho may have been indeed deplorable, but English law has not so far developed to the stage of treating it as criminal; and if it ever were to do so there would be difficulties in defining what should be the limits of the offence.” (25)

In the 15th century, Bishop Pecock instructed his readers to find blame for omissions if “oure conscience schulde deem us gilty” (26). But as Lord Diplock underlined, morality and the law, although closely connected, are different things. Some European countries like France and Germany penalise the failure to help a person in difficulty, if this can be done without endangering oneself (27). Along these lines, there have been calls for the creation of a general duty of care in English Law that would impose a criminal sanction on people who fail to give assistance (28) and Prof Ashworth is one of the main proponents. Speaking in a radio panel discussion on BBC Radio 4 in January 2015 (29), he said:

“I think we need to have a law that states there should be a duty to assist… At the moment, English law is untidy and unprincipled, and I think we ought to state this principle and bring it in as a law … I am suggesting we should have a clearer law that should tell people they should give assistance to others in a wide range of situations, and that offence [from failing to give assistance] is a middle-ranking offence.”

This would not only bring the law to the moral position which maintains that one should be “yielding … a good deed for another if one can”; it may be argued (and indeed it is argued) that it would simplify a little of the already mentioned “undesirable complexity”. As the law currently stands, it does criminalise omissions to act just as much as it criminalises positive acts. However, in a hybrid conventional and social responsibility view more attuned to contemporary sensibilities and moral compass, as that proposed by Ashworth (30), it might be more conducive to social cohesion to encourage citizen action and responsibility more, and punish some omissions less. It will also do something which the public generally welcomes: it could protect would-be good Samaritans from the possible sanction of the law. (31)

Is there any rational basis for the distinction which criminal law draws between acts and omissions

Is There Any Rational Basis for the Distinction Which Criminal Law Draws Between Acts and Omissions? How consistently is the Distinction Maintained?

An act is an action which directly or indirectly causes a result. In criminal law, a person is held liable for an action which, when the required mens rea[1] and actus reus[2] can jointly be proven to have caused harm to a person or property, unless they have a reasonable defence[3].

In contrast people are usually not convicted for their omissions: "it is evident that to punish men by law for not rendering to others all the service which it is their [moral] duty to render would be preposterous" [4]. Making all moral omissions a crime would encompass too many people and would create an oppressive society[5]. An omission in law is where action is not taken which would prevent or reduce the risk of harm or damage to a person or property, where a person has an obligation to act. A policeman in Dytham [1979] QB 722[6] was found guilty of misconduct whilst acting as an officer of justice, whilst as he was in uniform and on duty he stood by and failed to assist a man who was beaten to death by a doorman of a nightclub. His omission to act had contravened his statutory obligation to help, which his profession imposed on him.

Where a relationship or assumption of care is present, there is an automatic duty to act, so that if an omission to act results in "legally recognised harm"[7], liability may be applied. In Stone and Dobinson [1977], the court of appeal ruled that by assuming duty of care for his sister they were "obliged to summon help or care for the sister when she became infirm"[8]. Lord Atkin ruled that a sentence of manslaughter should be applied to the fatalistic omission, especially when it was proven that if help had been attained at the time of her last bathing, two weeks before her death, she would have survived.

A further scenario where liability is addressed for an omission is when "an initial inadvertent action results in harm which the defendant later knowingly fails to avert when the opportunity presents itself"7, represented by the case of R v Miller (James) [1982][9]. The Court of Appeal ruled that a coincidence of mens rea and actus rea is usually fundamental, however, "an unintentional act followed by an intentional act or, in appropriate cases, reckless omission to rectify it or its consequences, could be regarded together as an intentional act"[10]. The sequence of events from Miller’s accidental falling asleep with the lit cigarette in his hand, to discovering that the mattress was smouldering, to ignoring the fire hazard, and moving to a next room was considered, by the House of Lords, as one continuous reckless act. Miller was thus found liable for arson due to his omission to rectify the dangerous situation, which he himself had created, as soon as the opportunity arose.

When dissecting the elements of an omission and an act, many similarities are found. When deciding whether a person is liable for an act which results in causing criminal harm or damage, it must be considered whether the act was voluntary. For example in the case of murder, a person is found culpable if they are found to have the mens rea[11] and actus reus[12], which they voluntarily choose to perform. Yet, in order to refrain from acting, there has to be a voluntary decision to omit to act. In the case of Miller he voluntarily thought to leave the scene where the mattress was smouldering knowing that the mattress would most likely set alight, whereas a person who had voluntarily thrown a match onto the mattress would be convicted of the identical crime of arson. There becomes a point where decisions are paramount to whether a person is liable or not for a crime. In both acts and omissions the element of decision in both is what fails to conclude that it is rational to distinguish between them both.

When the implication of "intention" is used to define an element of actus reus and mens rea combined, it becomes clear that it may not be so rational to distinct between an act and omission. Liability for an act requires it to be proven that the actor had mens rea or the intention of causing harm or damage, yet it can be ascertained that for many criminal omissions the mens rea is the same, in that they know by not acting, harm or damage may still occur. It is thus questionable whether there should be such a clear distinction between the two. This may be exemplified by Fagan v Commissioner of Police Of the Metropolis [1968] where an originally accidental act of driving a car onto the foot of a police constable was then followed by the intentional mens rea resulting in a temporary refusal to remove the car from the foot. This element of mens rea adapts the incident, in the eyes of the law, to have become one long sequence of events, which technically since the actus reus[13] and the mens rea[14] would serve as proof, under normal circumstances as a criminally liable act. This suggests that it is not rational to draw such a distinction between an act and an omission.

However the distinction between acts and omissions is often criticised as the distinction can often differ simply on the way the situation is described. Reflecting on the case of Airedale NHS Trust v Bland [1993] where a request was brought to court by doctors of the hospital requesting permission to remove life-supporting machines. Lord Goff of Chieveley, in the House of Lords, ruled that it would be a legal omission due to the situation, as there was no duty for a doctor to prolong the life of an individual regardless of the circumstances. However, contrary to Lord Goff’s ruling it could also be viewed that the action was indeed an act of murder, complete with the necessary mens rea and actus reus[15]. It is thus that the distinction between an act and an omission becomes blurred and it wholly depends on how the sequence of events is described and on how the law views such sequence of events.

It is notable that in the case of a death, the causation lays equal weight on whether the result was caused either by an act or an omission. The fact that the maximum sentence for each[16] is a life-sentence highlights that there is not a rational basis for drawing a distinction between the two. A difficulty with this is highlighted in Smith [1979] S was charged with manslaughter for not receiving medical help, which would have saved his wife’s life if it had been received at the beginning of his wife’s deterioration of health. S contested that his wife had had a dislike of doctors and that it had been her request that he should not seek medical advice. S was held liable for his wife’s death. It is thus a concern whether acts and omissions should not be more clearly distinct from each other, in order to prevent similar convictions being placed onto defendant’s where the omission is not wholly voluntary, but which is not covered by the law, whereas actions have more distinct defences.

The distinction between an act and an omission is therefore not fully rational as in most cases the distinction is not fully maintained. It is often used to describe the sequence of events, yet it is often blurred with the term "act" in addressing culpability. Miller highlights controversy that by omitting to take action which would have prevented the extent of the fire, the entire sequence of events can be combined to equal one act, which disguises the distinction between an act and an omission.

However, the distinction between an act and an omission serves an important purpose, as it does serve to distinguish and highlight some behaviour that can only be solely classified as an omission to act, and are charged as thus, as in Dytham and many statutory motor offences. Also the distinction between an act and omission still serves to highlight some situations where a person is criminally liable for their omissions, where if there was no distinction, may be overlooked; even if the end result is that the person is convicted with the same terms as the voluntary act would enforce, as in Fagan v Commissioner of Police Of the Metropolis. However, rather than claim that it is irrational to distinct between an act and an omission, it may be considered that the way in which the courts handle the distinction between acts and omissions is unsuitable, to the effect that the distinction becomes irrational and useless.
