“In their Lordships’ opinion, the law relevant to this appeal may be stated in the following propositions (the formulation of which follows closely the written submission of the appellants’ counsel, which their Lordships gratefully acknowledge): (1) there is a presumption of law that mens rea is required before a person can be held guilty of a criminal offence; (2) the presumption is particularly strong where the offence is ‘truly criminal’ in character; (3) the presumption applies to statutory offences, and can be displaced only if this is clearly or by necessary implication the effect of the statute; (4) the only situation in which the presumption can be displaced is where the statute is concerned with an issue of social concern, and public safety is such an issue; (5) even where a statute is concerned with such an issue, the presumption of mens rea stands unless it can also be shown that the creation of strict liability will be effective to promote the objects of the statute by encouraging greater vigilance to prevent the commission of the prohibited act.”

“Sometimes the words of the section which creates a particular offence make it clear that mens rea is required in one form or another. Such cases are quite frequent. But in a very large number of cases there is no clear indication either way. In such cases there has for centuries been a presumption that Parliament did not intend to make criminals of persons who were in no way blameworthy in what they did. That means that whenever a section is silent as to mens rea there is a presumption that, in order to give effect to the will of Parliament, we must read in words appropriate to require mens rea. Where it is contended that an absolute offence has been created, the words of Alderson B in Attorney General v Lockwood (1842) 9 M & W 378, 398 have often been quoted: ‘The rule of law, I take it, upon the construction of all statutes, and therefore applicable to the construction of this, is, whether they be penal or remedial, to construe them according to the plain, literal, and grammatical meaning of the words in which they are expressed, unless that construction leads to a plain and clear contradiction of the apparent purpose of the Act, or to some palpable and evident absurdity.’ That is perfectly right as a general rule and where there is no legal presumption. But what about the multitude of criminal enactments where the words of the Act simply make it an offence to do certain things but where everyone agrees that there cannot be a conviction without proof of mens rea in some form? This passage, if applied to the present problem, would mean that there is no need to prove mens rea unless it would be ‘a plain and clear contradiction of the apparent purpose of the Act’ to convict without proof of mens rea. But that would be putting the presumption the wrong way round: for it is firmly established by a host of authorities that mens rea is an essential ingredient of every offence unless some reason can be found for holding that that is not necessary.”
“The notion that some guilty mind is a constituent part of crime and punishment goes back far beyond our common law.” “Our first duty is to consider the words of the Act: if they show a clear intention to create an absolute offence that is an end of the matter. But such cases are very rare.”
“The question must always be - what has Parliament enacted?”
“[t]he inquiry must be made … whether Parliament has used words which expressly enact or impliedly involve that an absolute offence is created.”
“It is to be observed that section 116 itself contains a number of offences set out consecutively and joined by the conjunction ‘or’. It is sufficient to say that some of these would plainly require to be construed so that no offence would be constituted unless mens rea were established. For example, the words ‘should any person counterfeit, falsify or wilfully use when counterfeited or falsified any document required by or produced to any officer of customs.’ would not in their Lordships’ view be satisfied in the absence of proof of mens rea. It does not, however, follow that all the phrases in the section must be read in the same way, and the making of a false entry may well be in this as in other similar statutes relating to customs absolutely prohibited within the exceptions to the general rule applicable to statutes creating criminal offences. The distinction must be a narrow one in considering the various parts of the section if the conclusion is correct that one cannot ‘falsify’ without a guilty mind but that one can innocently make a ‘false’ entry. Notwithstanding the narrowness of the distinction their Lordships are of opinion that this difficulty must be faced. On behalf of the appellant reliance was placed on the minimum penalty of£50 provided by the section as an indication that proof of mens rea must be required. No doubt this is a relevant consideration but it is to be noted that in other similar statutes a standard penalty of£100 is fixed and has not been held to have imported the necessity of proof of mens rea. … In these cases the language of Wright J in Sherras v De Rutzen[1895] 1 QB 918 , 921 has often been considered and serves as a useful guide to the proper construction of the statutes under consideration. He says: ‘There is a presumption that mens rea, an evil intention, or a knowledge of the wrongfulness of the act, is an essential ingredient in every offence; but that presumption is liable to be displaced either by the words of the statute creating the offence or by the subject-matter with which it deals, and both must be considered.’ Their Lordships have not overlooked the judgment of the board in Lim Chin Aik v The Queen. That case concerned the presumption that mens rea is an essential ingredient in every offence and was much relied upon by the appellant, but their Lordships find nothing in the judgment of the board delivered by Lord Evershed to lead them to the conclusion that a construction should be placed upon section 116 which involves the addition by implication of the word ‘knowingly’ before the words ‘make any false entry’. They are of opinion that the decision of the learned judge in giving the opinion of the Supreme Court as to the meaning to be assigned to the word ‘false’ is correct and that on this point the appeal would fail, since the offence of which the appellant was convicted was absolute and no proof of mens rea was required.”
“It is also firmly established that the fact that other sections of the Act expressly require mens rea, for example because they contain the word ‘knowingly’, is not in itself sufficient to justify a decision that a section which is silent as to mens rea creates an absolute offence. In the absence of a clear indication in the Act that an offence is intended to be an absolute offence, it is necessary to go outside the Act and examine all relevant circumstances in order to establish that this must have been the intention of Parliament. I say ‘must have been’ because it is a universal principle that if a penal provision is reasonably capable of two interpretations, that interpretation which is most favourable to the accused must be adopted.”
“One must put oneself in the position of a legislator.”
“The severity of the maximum penalties is a more formidable point. But it has to be considered in the light of the Ordinance read as a whole. For reasons which their Lordships have already developed, there is nothing inconsistent with the purpose of the Ordinance in imposing severe penalties for offences of strict liability. The legislature could reasonably have intended severity to be a significant deterrent, bearing in mind the risks to public safety arising from some contraventions of the Ordinance. Their Lordships agree with the view on this point of the Court of Appeal. It must be crucially important that those who participate in or bear responsibility for the carrying out of works in a manner which complies with the requirements of the Ordinance should know that severe penalties await them in the event of any contravention or non-compliance with the Ordinance by themselves or by anyone over whom they are required to exercise supervision or control.”
“there [is] something [the defendant] can do, directly or indirectly, by supervision or inspection, by improvement of his business methods or by exhorting those whom he may be expected to influence or control, which will promote the observance of the regulations” (per Lord Evershed, giving the advice to Her Majesty in Lim Chin Aik v The Queen[1963] AC 160 at p 174).”
“There have been many cases in recent periods in which in reference to a variety of different statutory enactments questions have been raised whether absolute offences have been created. … I do not propose to recite or survey these cases because, in my view, the principles which should guide construction are clear and, save to the extent that principles are laid down, the cases merely possess the interest which is yielded by seeing how different questions have, whether correctly or incorrectly, been decided in reference to varying sets of words in various different statutes.”
