Privy Council -- Singapore -- Criminal law -- Mens rea -- Immigration -- Entry -- Order prohibiting individual entering Singapore -- Ordinance silent on whether order should be served -- No evidence that order served or individual notified of it -- Contravention of order -- Whether mens rea an essential element of offence -- Whether ignorance of the law no excuse -- Immigration Ordinance, 1952 (c. 102), as amended by Ordinance, 1959 (No. 22).
Held:In 1959 the appellant, who previously had lived in Singapore with his family, but had left in 1954 in suspicious circumstances, began to visit Singapore daily. On May 28, 1959, an order was made under the Singapore Immigration Ordinance, s. 9 *, prohibiting the appellant entering Singapore. In June, 1959, he began to live with his family again in Singapore. The appellant was convicted under s. 6 (2), (3) n+ of the ordinance, as amended, which enacted that it should not be lawful for a person prohibited by order from entering Singapore to enter Singapore and rendered such entry into, or remaining in Singapore, an offence. There was no evidence that the order was served on or communicated to the appellant, and it was conceded that mens rea on his part had not been proved. Section 9 (3) of the ordinance provided for publication of orders directed to a class of persons, but not for publication of an order directed to an individual. Various provisions of the ordinance, other than s. 6 and s. 9, contained phrases such as "knowingly", "without reasonable cause" or "without reasonable excuse" in relation to the doing of an act, as distinct from the passive continuance of behaviour previously lawful; but not such phrase appeared in s. 9 or s. 6. On appeal, * Section 9 of the ordinance, so far as relevant, is printed at p. 225, letter F, post. The short title of the ordinance is the "Immigration Ordinance"; it was No. 5 of 1952 and is Chapter 102 as published in the Laws of the Colony of Singapore (Revised Edn., 1955), containing the ordinances in force on May 1, 1955, see Vol. 2, pp. 414 et seq. n+ Section 6 (2) and (3) of the ordinance, so far as relevant, are printed at p. 226, letter A, post. Held: (1) the principle that ignorance of the law was no excuse was inapplicable where, as here (even if the making of the order prohibiting the appellant's entry was a legislative, as distinct from an administrative act), there was no legislative provision for the publication of the order or designed to enable the man concerned to find out by appropriate inquiry what the law affecting him in this respect was (see p. 226, letter I, to p. 227, letter A, post). (ii) the presumption that mens rea was an essential ingredient of the offence had not been ousted either by the terms of the Singapore Immigration Ordinance, or by its subject-matter, (a) notwithstanding, as regards the construction of the ordinance, the absence from s. 6 of such a word as "knowingly" or a comparable qualification which were to be found in other sections, and (b), in regard to the subject-matter of the ordinance, particularly for the reason that to impose absolute liability on a prohibited person could not have ensured observance of the order, since he could not have complied with it if he did not know if it and no practicable means of his ascertaining that he had become a prohibited person was provided by the ordinance (see p. 230, letter D, p. 227, letter H, to p. 228, letter A, and p. 229, letter E, post). Principle stated by WRIGHT, J., in Sherras v. De Rutzen ( 1 Q.B. at p. 921), and dictum of LORD GODDARD, C.J., in Brend v. Wood ((1946), 175 L.T. at p. 307) approved. Dictum of DAY, J., in Sherras v. De Rutzen ( 1 Q.B. at p. 921) disapproved. Per CURIAM: where it can be shown that the imposition of strict liability would result in the prosecution and conviction of a class of persons whose conduct could not in any way affect the observance of the law, then, even where the statute is dealing with a grave social evil, strict liability is not likely to be intended (see p. 229, letter B, post). Appeal allowed.

Introduction:Appeal. This was an appeal against the decision of the High Court of the State of Singapore of Feb. 24, 1960, which, without giving reasons, dismissed the appellant's appeal against his conviction by the Magistrate's Court of Singapore (P.T.K. LAU, ESQ.) on Aug. 17, 1959. The appellant was charged with unlawfully entering and remaining in Singapore after an order of prohibition had been made against him under the Immigration Ordinance, 1952, as amended by the Singapore Ordinance, 1959 (No. 22). There was no evidence that the order had been served on the appellant or brought to his notice and it was contended on behalf of the appellant, who did not give evidence, that there was no case to answer as he had no knowledge of the order. The learned magistrate rejected the submission and in his grounds of decision stated his reasons as follows:
"Finally, it was contended for the defence that the order should be personally served on the accused. Counsel for the Crown replied that it was unnecessary under s. 9 of the ordinance. My view was that the ordinance was silent on the matter and that, once the order was made, it took effect whether the accused knew of its existence or not."The appellant was sentenced to a fine of $1,250 or three months' imprisonment in default of payment.
Counsel:E. F. N. Gratiaen, Q.C., and D. Taverne for the appellant. J. G. Le Quesne, Q.C., and Mervyn Heald for the respondent.
PANEL:Viscount Radcliffe, Lord Evershed and Lord Devlin
Judgment One:LORD EVERSHED: The appellant Lim Chin Aik (who appears to have been known by several other names but to whom their Lordships will hereafter refer s "the appellant") has appealed to the Board by special leave from the dismissal on Feb. 24, 1960, by the High Court of Singapore of his appeal against conviction by a magistrate on Aug. 27, 1959, for an offence under s. 6 of the Immigration Ordinance, n(1), ofthe State of Singapore (as later amended) and the sentence then imposed of a fine of $1,250 or three months' imprisonmnet. The relevant facts fall within a small compass but the point involved in the appeal is one, their Lordships think, of no little importance. n(1) See p. 226, letter A, post. The appellant appears to have been born in China about the year 1900. It is unnecessary to relate his history beyond stating that, after living in Singapore with his wives and children, he left Singapore in 1954 in circumstandes apparently of some suspicion. At the beginning of 1959 he was living in the Federation of Malaya. He then began to visit Singapore and his family daily, returning each night to the Federation. At some time, according to a statement made by the appellant to the police, "more than ten days before June 29, 1959" the appellant began to live in Singapore with his wives and children. On June 29 the appellant was discvered by a police officer of Singapore who was making a search for narcotics and he was then arrested. The appellant was first charged on July 1, 1959, with hving entered the State of Singapore about May 17, 1959, without a valid permit, thereby contravening s. 6 (1) of the Immigration Ordinance. At the trial of the appellant this charge was abandoned by the prosecution and it need not therefore further be considered. A second charge was dated Aug. 15, 1959 (two days in fact before the appellant's trial). This charge was in the following terms:
"... you... having entered Singapore from the Federation of Malaya in May, 1959, did remain therein whilst prohibited by an order made by the minister under s. 9 prohibiting you from entering Singapore and have thereby contravened s. 6 (2) of the Immigration Ordinance, an offence under s. 6 (3) punishable under s. 57 thereof."Their Lordships will refer now to the relevant terms of the ordinance of 1952 (as amended n(2); the amending ordinance came into operation on May 1, 1959). Section 9 (1) of the amended Immigration Ordinance n(3), so far as relevant, is in the following terms: n(2) The Immigration Ordinance was amended by the Immigration (Amendment) Ordinance, 1959 (No. 22). n(3) Section 9 of the Immigration Ordinance was amended by s. 6 of the Immigration (Amendment) Ordinance, 1959 (No. 22).
"The minister may, by order -- (a) where he deems it expedient to do so in the interests of public security or by reason of any economic, industrial, social, educational or other conditions in Malaya -- (i) prohibit, either for a stated period or permanently, the entry or re-entry into the colony of any person or class of persons;"Subsection (3) of the same section states: "(a) Every order made under sub-s. (1) of this section shall unless it be otherwise provided in such order take effect and come into operatio on the date on qhixh ir ia made.
"(b) Every order made under sub-s. (1) of this section which relates to a class of persons shall be published in the Gazette and, except an order made in the interests of public security, shall be presented to the Legislative Assembly as soon as may be after publicatioin and if a resolution is passed pursuant to a motion... annulling the order or any part thereof as from a specified date, such order or such part thereof, as the case may be, shall thereupon become void as from such date but without prejudice to the validity of anything previously done thereunder or to the making of a new order."It will be noticed that in the case of an order directed to a single person as distinct from one directed to a class of persons there is not in the section (nor is there elsewhere in the ordinance) any provision for publishing the order or for otherwise bringing it (actually or notionally) to the attention of the person named. By s. 6 (2) of the amended ordinance n(4) it is provided: n(4) Section 6 of the Immigration Ordinance was amended by s. 3 of the Immigration (Amendment) Ordinance, 1959 (No. 22). "It shall not be lawful for any person other than a citizen of Singapore to enter Singapore from the Federation or having entered Singapore from the Federation to remain in Singapore if -- (b) such person has been prohibited by order made under s. 9 of this ordinance from entering Singapore"; By sub-s. (3) of the same section it is provided that
"Any person who contravenes the provisions of sub-s.... (2) of this section shall be guilty of an offence against this ordinance."Finally, s. 57 of the ordinance provides that any person guilty of an offence under the ordinance for which no special penalty is provided shall be liable on conviction to imprisonment for a term not exceeding six months or to a fine not exceeding $2,000 or to both such imprisonment and fine. It is not in dispute that pursuant to s. 9 of the ordinance above recited the Minister of Labour and Welfare did make, on May 28, 1959, an order prohibiting the appellant from entering Singapore. At the trial (which as already stated took place on Aug. 17, 1959) it was proved by the Deputy Assistant Controller of Immigration that the minister's order was received by him on the day on which it was made; but there was no evidence of what was done with the order thereafter and no evidence of any step having been taken by way of publication or otherwise so as to bring the order to the attention of the appellant -- or indeed of anyone else. The appellant at his trial did not personally give any evidence at all. It follows from the foregoing recital of facts that there was at the trial no evidence at all from which it could be properly inferred that the order had in fact come to the notice or attention of the appellant. It was therefore said on the appellant's behalf before the magistrate that, since there was no evidence of guilty intent on his part and that since such a guilty intent on general principles must be an ingredient of any criminal offence, it therefore followed that no offence had been proved against the appellant under the ordinance. This plea was rejected by the magistrate who, basing himself on the terms of the relevant section of the ordinance, held that there was in this case no need for any evidence of mens rea. The appellant then appealed to the High Court of Singapore but that court dismissed his appeal without stating any reason for the dismissal. Counsel for the appellant before their Lordships took as his first point the contention which had been rejected in the courts below, namely, that the absence of any evidence ofthe guilty intent of the appellant was fatal to the validity of his conviction. He argued, secondly, that if, as he contended, mens rea was an essential ingredient of an offence under s. 6 (3) of the ordinance, then the onus of proof of its existence lay on the prosecution. Counsel for the respondent challenged the first of counsel for the appellant's submissions but conceded the validity of his second point on the hypothesis that the first was well founded. In the event, therefore, it is with the question whether a guilty mind is a necessary requisite for the establishment of an offence under the relevant section that their Lordships are alone concerned and, as their Lordships have already observed, the question is one, as they venture to think, of substance and importance. It is convenient at once to dispose of counsel for the respondent's first suggested answer to this question, which was an invocation of the precept that ignorance of the law is no excuse. It was said on the respondent's part that the order made by the minister under the powers conferred by s. 9 of the ordinance was an instance of the exercise of delegated legislation and therefore that the order, once made, became part of the law of Singapore of which ignorance could provide no excuse on a charge of contravention of the section. Their Lordships are unable to accept this contention. In their Lordships' opinion, even if the making of the order by the minister be regarded as an exercise of the legislative as distinct from the executive or administrative function (as they do not concede), the maxim cannot apply to such a case as the present where it appears that there is in the State of Singapore no provision, corresponding, for example, to that contained in s. 3 (2) of the English Statutory Instruments Act, 1946, for the publication in any form of an order of the kind made in the present case or any other provision designed to enable a man by appropriate inquiry to find out what "the law" is. In this connexion it is to be observed that a distinction is drawn in the ordinance itself between an order directed to a particular individual on the one hand and an order directed to a class of persons on the other; for sub-s. (3) (b) of s. 9 provides in the latter case both for publication in the Gazette and presentation to the Legislative Assembly. Their Lordships return accordingly to the main question. That proof of the existence of a guilty intent is an essential ingredient of a crime at common law is not at all in doubt. The problem is of the extent to which the same rule is applicable in the case of offences created and defined by statute or statutory instrument. Their Lordships were very properly referred to a number of cases including the often cited Nichols v. Hall n(5) and Cundy v. Le Cocq n(6) and covering a considerable period ending with the decision last year of the Court of Criminal Appeal in R. v. Cugullere n(7). As was observed by WRIGHT, J., at the beginning of his judgment in Sherras v. De Rutzen n(8) to which their Lordships will presently make further reference, the difficulty of the problem is enhanced by the fact that many of the cases are not easy to reconcile. Thus it has been held that a licensee of a public house commits an offence under the licensing legislation of serving alcoholic liquor to a drunken man even though he was unaware of the customer's condition (Cundy v. Le Cocq n(6)); but that a licensee does not commit the offence under the same legislation of serving drinks to a police constable on duty if he reasonably supposed that the constable was in fact off duty (see Sherras v. De Rutzen n(8)): and in the latest case above cited the Court of Criminal Appeal n(9) held that the terms of s. 1 (1) of the Prevention of Crime Act, 1953, viz.: n(5) (1873), L.R. 8 C.P. 322. n(6) (1884), 13 Q.B.D. 207. n(7)  2 All E.R. 343. n(8)  1 Q.B. 918 at p. 921. n(9)  2 All E.R. at p. 344.
"Any person who without lawful authority or reasonable excuse, the proof whereof shall lie on him, has with him in any public place any offensive weapon shall be guilty of an offence..."must be read as if the word "knowingly" were written before the word "has". Counsel for the appellant founded his argument on the formulation of the problem contained in the judgment of WRIGHT, J., in Sherras v. De Rutzen n(10). The language of that learned and experienced judge was as follows: n(10)  1 Q.B. at p. 921.
"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..."It is to be observed that in that case the court held the presumption not to be displaced even though the word "knowingly", which was not found in the subsection involved in the case, did appear in another subsection of the same section. Their Lordships add that the circumstance last mentioned was regarded by DAY, J., in his judgment n(10) in the same case as shifting the onus of proof to the defendant (which onus the learned judge held to have been discharged). The question of onus does not, as already stated, arise in the present case. Their Lordships think it right, however, to say that they should not be thought to assent to the proposition of DAY, J. -- and they have in this respect noted that counsel for the respondent has not so contended. n(10)  1 Q.B. at p. 921. Their Lordships accept as correct the formulation cited from the judgment of WRIGHT, J. They are fortified in that view by the fact that such formulation was expressly accepted by LORD DU PARCQ in deliving the judgment of the Board in Srinivas Mall Bairolia v. King Emperor n(11) a case which unfortunately has not found its way into the law reports. That was a case in which one of the appellants had been charged with an offence under the rules made by virtue of the Defence of India Act, 1939, consisting of the sale of salt at prices exceeding those prescribed under the rules, the sales having in fact been made without that appellant's knowledge by one of his servants. The Indian High Court had held the appellant to be none the less liable on the terms of the rules; but the Board rejected the view of the High Court. LORD DU PARCQ n(12), after citing with approval the judgment already quoted of WRIGHT, J. n(13), also adopted n(14) the language of LORD GODDARD, C.J., in Brend v. Wood n(15): n(11) (1947), I.L.R. (Patna Series) 460. n(12) (1947), I.L.R. (Patna Series) at p. 468. n(13)  1 Q.B. at p. 921. n(14) (1947), I.L.R. (Patna Series) at p. 469. n(15) (1946), 62 T.L.R. 462 at p. 463.
"It is in my opinion of the utmost importance for the protection of the liberty of the subject that a court should always bear in mind that unless a statute either clearly or by necessary implication rules out mens rea as a constituent part of a crime a defendant should not be found guilty of an offence against the criminal law unless he has got a guilty mind." The adoption of these formulations of principle does not, however, dispose of the matter. Counsel for the respondent, indeed, as their Lordships understood, did not challenge the formulations. But the difficulty remains of their application. What should be the proper inferences to be drawn from the language of the statute or statutory instrument under review -- in this case of s. 6 and s. 9 of the Immigration Ordinance? More difficult perhaps still: what are the inferences to be drawn in a given case from the "subject-matter with which [the statute or statutory instrument] deals?"Where the subject-matter of the statute is the regulation for the public welfare of a particular activity -- statutes regulating the sale of food and drnk are to be found among the earliest examples -- it can be and frequently has been inferred that the legislature intended that such activities should be carried out under conditions of strict liability. The presumption is that the statute or statutory instrument can be effectively enforced only if those in charge of the relevant activities are made responsible for seeing that they are complied with. When such a presumption is to be inferred, it displaces the ordinary presumption of mens rea. Thus sellers of meat may be made responsible for seeing that the meat is fit for human consumption and it is no answer for them to say that they were not aware that it was polluted. If that were a satisfactory answer, then as KENNEDY, L.J., pointed out in Hobbs v. Winchester Corpn. n(16) the distribution of bad meat (and its far-reaching conseuences) would not be effectively prevented. So a publican may be made responsible for observing the condition of his customers, Cundy v. Le cocq n(17). n(16)  2 K.B. 471 at pp. 482-485. n(17) (1884), 13 Q.B.D. 207. But it is not enough in their Lordships' opinion merely to label the statute as one dealing with a grave social evil and from that to infer that strict liability was intended. It is pertinent also to inuire whether putting the defendant under strict liability will assist in the enforcement of the regulations. That means that there must be something he 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. Unless this is so, there is no reason in penalising him, and it cannot be inferred that the legislature imposed strict liability merely in order to find a luckless victim. This principle has been expressed and applied in Reynolds v. G. H. Austin & Sons, Ltd. n(18) and James & Sons, Ltd. v. Smee, Green v. Burnett n(19). Their Lordships prefer it to the alternative view that strict liability follows simply from the nature of the subject-matter and that persons whose conduct is beyond any sort of criticism can be dealt with by the imposition of a nominal penalty. This latter view can perhaps be supported to some extent by the dicta of KENNEDY, L.J., in Hobbs v. Winchester Corpn. n(20) and of DONOVAN, J., in R. v. St. Margaret's Trust, Ltd. n(21). But though a nominal penalty may be appropriate in an individual case where exceptional lenience is called for, their Lordships cannot, with respect, suppose that it is envisaged by the legislature as a way of dealing with offenders generally. Where it can be shown that the imposition of strict liability would result in the prosecution and conviction of a class of persons whose conduct could not in any way affect the observance of the law, their Lordships consider that, even where the statute is dealing with a grave social evil, strict liability is not likely to be intended. n(18)  1 All E.R. 606;  2 K.B. 135. n(19)  3 All E.R. 273;  1 Q.B. 78. n(20)  2 K.B. at p. 485. n(21)  2 All E.R. 289 at p. 293. Their Lordships apply these general observations to the Immigration Ordinance in the present case. The subject-matter, the control of immigration, is not one in which the presumption of strict liability has generally been made. Nevertheless, if the courts of Singapore were of the view that unrestricted immigration is a social evil which it is the object of the ordinance to control most rigorously, their Lordships would hesitate to disagree. That is a matter peculiary within the cognisance of the local courts. But counsel for the respondent was unable to point to anything that the appellant could possibly have done so as to ensure that he complied with the regulations. It was not, for example, suggested that it would be practicable for him to make continuous inquiry to see whether an order had been made against him. Clearly one of the objects of the ordinance is the expulsion of prohibited persons from Singapore, but there is nothing that a man can do about it if, before the commission of the offence, there is no practical or sensible way in which he can ascertain whether he is a prohibited person or not. Counsel for the respondent, therefore, relied chiefly on the text of the ordinance and their Lordships return, accordingly, to the language of the two material sections. It is to be observed that the Board is here concerned with one who is said (within the terms of s. 6 (3)) to have "contravened" the subsection by "remaining" in Singapore (after having entered) wen he had been "prohibited" from entering by an "order" made by the ministry containing such prohibition. It seems to their Lordships that, where a man is said to have contravened an order or an order of prohibition, the common sense of the language presumes that he was aware of the order before he can be said to have contravened it. Their Lordships realise that this statement is something of an oversimplification when applied to the present case: for the "contravention" alleged is of the unlawful act, prescribed by sub-s. (2) of the section, of remaining in Singapore after the date of the order of prohibition. None the less it is their Lordships' view that, applying the test of ordinary sense to the language used, the notion of contravention here alleged is more consistent with the assumption that the person charged had knowledge of the order than the converse. But such a conclusion is in their Lordships' view much reinforced by the use of the word "remains" in its context. It is to be observed that if the respondent is right a man could lawfully enter Singapore and could thereafter lawfully remain in Singapore until the moment when an order of prohibition against his entering was made; that then, instanter, his purely passive conduct in remaining -- that is, the mere continuance, quite unchanged, of his previous behaviour, hitherto perfectly lawful -- would become criminal. These considerations bring their Lordships clearly to the conclusion that the sense of the language here in question requires for the commission of a crime thereunder mens rea as a constituent of such crime; or at least that there is nothing in the language used which suffices to exclude the ordinary presumption. Their Lordships do not forget the emphasis placed by counsel for the respondent on the fact that the word "knowingly" or the phrases "without reasonable cause" or "without reasonable excuse" are found in various sections of the ordinance (as amended) but find no place in the section now under consideration -- see for example s. 16 (4), s. 18 (4), s. 19 (2), s. 29, s. 31 (2), s. 41 (2) and s. 56 (d) and (e) of the ordinance. In their Lordships' view the absence of such a word or phrase in the relevant section is not sufficient in the present case to prevail against the conclusion which the language as a whole suggests. In the first place, it is to be noted that to have inserted such words as "knowingly" or "without lawful excuse" in the relevant part of s. 6 (3) of the Immigration Ordinance would in any case not have been sensible. Further, in all the various instances where the word or phrase is used in the other sections of the ordinance before-mentioned the use is with reference to the doing of some specific act or the failure to do some specific act as distinct from the mere passive continuance of behaviour theretofore perfectly lawful. Finally, their Lordships are mindful that in the Sherras case n(22) itself the fact that the word "knowingly" was not found in the subsection under consideration by the court but was found in another subsection of the same section was not there regarded as sufficient to displace the ordinary rule. n(22)  1 Q.B. 918. Their Lordships have accordingly reached the clear conclusion, with all respect to the view taken in the courts below, that the application of the rule that mens rea is an essential ingredient in every offence has not in the present case been ousted by the terms or subject-matter of the ordinance and that the appellant's conviction and sentence cannot stand. Their Lordships will accordingly humbly advise Her Majesty that this appeal ought to be allowed and the conviction of the appellant and the sentence imposed on him ought to be quashed. Their Lordships also are of opinion that the respondent ought to pay the costs of the appellant's appeal to the Board.
