354S<strong>in</strong>gapore <strong>Academy</strong> <strong>of</strong> <strong>Law</strong> Journal (2006)with the question <strong>of</strong> whether or not the concept <strong>of</strong> the reasonable personencompassed certa<strong>in</strong> peculiarities – the hold<strong>in</strong>g there was that, assum<strong>in</strong>gwe know the characteristics <strong>of</strong> the reasonable person, is the standard <strong>of</strong>negligence simple, gross or <strong>in</strong>termediate? It would have been entirelyconsistent for the court <strong>in</strong> Ng Keng Yong to have held that, although thetest <strong>of</strong> simple negligence applied, the relevant reasonable person was anord<strong>in</strong>arily competent tra<strong>in</strong>ee.73 The court then advanced several substantive argumentssupport<strong>in</strong>g the use <strong>of</strong> Nettleship <strong>in</strong> crim<strong>in</strong>al cases. Whatever itsdesirability <strong>in</strong> civil cases, I am concerned here only with itstransplantation <strong>in</strong>to the crim<strong>in</strong>al context. Just as <strong>in</strong> Lim Poh Eng, thecourt once aga<strong>in</strong> demonstrated its aversion to ambiguity and uncerta<strong>in</strong>ty.The truth is that the concept <strong>of</strong> the reasonable person is <strong>in</strong>herentlyuncerta<strong>in</strong>. People are not the same, and when you impose on them theconcept <strong>of</strong> “a reasonable person” you <strong>in</strong>evitably have to decide which <strong>of</strong>those characteristics <strong>of</strong> the person at hand ought to be transposed to thereasonable person, and which should not. The court ought to haverecognised that this <strong>in</strong>herent ambiguity is not conf<strong>in</strong>ed to s 304A. TheChief Justice had himself spelt out a far more sensitive and workableapproach to crim<strong>in</strong>al negligence <strong>in</strong> a slightly different context. In KohHak Boon v PP, 118the Chief Justice had to expla<strong>in</strong> the standard <strong>of</strong>negligence embodied <strong>in</strong> the <strong>of</strong>fence <strong>in</strong> s 414 <strong>of</strong> the Penal Code:Whoever voluntarily assists <strong>in</strong> conceal<strong>in</strong>g or dispos<strong>in</strong>g <strong>of</strong> or mak<strong>in</strong>gaway with property which he knows or has reason to believe to be stolenproperty, shall be punished with imprisonment for a term which mayextend to 3 years, or with f<strong>in</strong>e, or with both. [emphasis added]74 The Chief Justice had this to say about the reasonable person <strong>in</strong>the context <strong>of</strong> crim<strong>in</strong>al law and it deserves to be quoted at length: 119Whether or not a person had ‘reason to believe’ certa<strong>in</strong> property wasstolen property … is a test to be applied by the court, but from theperspective <strong>of</strong> the accused person. It must relate to the standards <strong>of</strong>belief <strong>of</strong> a reasonable man and not to those <strong>of</strong> any particular accusedperson, s<strong>in</strong>ce the legislature could hardly have <strong>in</strong>tended that, ceterisparibus, a conviction might depend on whether the accused reasons likea cret<strong>in</strong> or a genius. However, some element <strong>of</strong> subjectivity must be<strong>in</strong>volved, because what might be apparent to a person with specializedknowledge <strong>of</strong> a certa<strong>in</strong> field might not be apparent to a layman <strong>of</strong> evenvery high <strong>in</strong>telligence. For example, a jewellery expert might be able to118 [1993] 3 SLR 427.119 Id, at 430, [13].
