358S<strong>in</strong>gapore <strong>Academy</strong> <strong>of</strong> <strong>Law</strong> Journal (2006)One can perhaps be cautiously optimistic that this alternative approachwill eventually prevail throughout the crim<strong>in</strong>al law.IV.Strict liability: Spoilt for choice83 The question <strong>of</strong> what a court is supposed to do when theLegislature is silent concern<strong>in</strong>g a mens rea requirement has long exercisedthe m<strong>in</strong>ds <strong>of</strong> observers <strong>of</strong> the S<strong>in</strong>gapore crim<strong>in</strong>al law. 123Earliercommentaries discern a dichotomy <strong>of</strong> approaches. 124Some courtsadopted the methodology <strong>of</strong> the English common law. 125Briefly, thisrequired the court to apply an <strong>in</strong>itial presumption that the prosecution isto prove full (and actual) knowledge <strong>of</strong> the fact <strong>in</strong> question. Then thecourt is to undertake an analysis <strong>of</strong> whether the Legislature impliedly<strong>in</strong>tended mens rea not to be a requirement <strong>of</strong> the <strong>of</strong>fence. Various pieces<strong>of</strong> circumstantial evidence are said to go <strong>in</strong>to this task – whether thecreation <strong>of</strong> the <strong>of</strong>fence was a matter <strong>of</strong> social concern or for theprotection <strong>of</strong> the public, whether the <strong>of</strong>fence carried a social stigma orparticularly severe penalties, whether the omission <strong>of</strong> a mens rearequirement will promote observance <strong>of</strong> the legislation. 126If thepresumption <strong>of</strong> mens rea is not rebutted, then full knowledge must beproved by the prosecution. If the presumption is rebutted, then the<strong>of</strong>fence becomes one <strong>of</strong> strict liability and the presence or absence <strong>of</strong>mens rea is irrelevant to liability. Cases which have used this approachhave come out one way or the other, <strong>of</strong>ten without any conv<strong>in</strong>c<strong>in</strong>g reasonwhy the result ought to have been so. 12784 The other cases choose what has been called the Penal Codeapproach – so called because it focuses on s 79 <strong>of</strong> the Penal Code which123 For what is perhaps the first, see McKillop, “Strict Liability Offences <strong>in</strong> S<strong>in</strong>gaporeand Malaysia”, supra n 48, which ends with an <strong>in</strong>dictment (at 144) which,unfortunately still r<strong>in</strong>gs true: “It seems almost that for every case <strong>in</strong> which the courtshere have opted for mens rea another case on the same or a similar <strong>of</strong>fence can befound <strong>in</strong> which liability has been held to be strict, and vice-versa.”124 See for example, M Sornarajah, “Defences to Strict Liability Offences <strong>in</strong> S<strong>in</strong>gaporeand Malaysia” (1985) 27 Mal LR 1 at 6, which speaks <strong>of</strong> a “two track system <strong>of</strong>crim<strong>in</strong>al law”.125 See, for example, PP v Mohamed Ibrahim [1963] MLJ 289 (<strong>of</strong>fence <strong>of</strong> possession <strong>of</strong>obscene books for sale deemed to be <strong>of</strong> strict liability), a case which is all the morestrik<strong>in</strong>g as it had to do with the imposition <strong>of</strong> strict liability on a Penal Code <strong>of</strong>fence.126 This last factor came to the fore <strong>in</strong> a Privy Council decision from S<strong>in</strong>gapore: LimCh<strong>in</strong> Aik v R [1963] MLJ 50.127 See, for example, Michael Hor, “Strict Liability <strong>in</strong> Crim<strong>in</strong>al <strong>Law</strong>: A Re-Exam<strong>in</strong>ation”[1996] S<strong>in</strong>g JLS 312, my earlier attempt to explore the issue.
