¹ R. v G and another [2003] UKHL 50, [2004] 1 A.C. 1034, 1057. Strictly speaking, the ruling in G was only intended to cover the meaning of “recklessness” in relation to criminal damage (see Lord Bingham's comments at 1054). However, a number of judgments have not followed this restriction: see the cases noted in Stark, F., Culpable Carelessness: Recklessness and Negligence in the Criminal Law (Cambridge 2016), 27, note 6CrossRefGoogle Scholar.

² For criminal damage, see the Criminal Damage Act 1971, ss. 1(1), 1(2)(a). For assault and battery (case law does not discriminate between these offences on mens rea issues), see R. v Spratt [1990] 1 W.L.R. 1073 (C.A.); R. v Savage & R. v Parmenter [1992] 1 A.C. 699 (C.A.).

³ B (a Minor) v DPP [2000] 2 A.C. 428, 462. Previous cases established the principle that there is a presumption of mens rea: see Sweet v Parsley [1970] A.C. 132, 148. B added that this should be understood subjectively, i.e. as a presumption of at least recklessness. Not all common law systems read the presumption in this way. Some non-UK Commonwealth jurisdictions, such as Canada, Australia, and New Zealand, have a presumption that offences at least require negligence (by means of having a universally applicable “due diligence” defence). This alternative was discussed in Sweet v Parsley (at, e.g., 150, 157–58), but was not adopted, as the justices thought it to be inconsistent with the presumption of innocence established in Woolmington v DPP [1935] A.C. 462. For discussion, see Simester, A.P., Spencer, J.R., Stark, F., Sullivan, G.R. and Virgo, G.J., Simester and Sullivan's Criminal Law: Theory and Doctrine, 7th ed. (Oxford 2019), 213–15Google Scholar.

¹² DPP v Beard [1920] A.C. 479; DPP v Majewski [1977] A.C. 443. This only applies to offences of “basic intent”, and not to those of “specific intent”. Paradigmatic examples of crimes of specific intent are murder, wounding with intent, causing GBH with intent, theft, burglary, and handling stolen goods, and most other crimes are of basic intent. However, it is not clear what is supposed to mark the basic/specific intent distinction – for discussion, see Ormerod, D. and Laird, K., Smith and Hogan's Criminal Law, 15th ed.

An argument of this structure is also made by criminal negligence sceptics, who combine it with objections to tracing approaches, leaving scepticism the only option: see, in particular, Alexander, L. and Ferzan, K.K., Crime and Culpability: A Theory of Criminal Law (Cambridge 2009), ch. 3CrossRefGoogle Scholar. Some defenders of indirect approaches to culpable ignorance (e.g. Zimmerman, “Negligence and Moral Responsibility”; Rosen, “Skepticism about Moral Responsibility”) claim it leads to a general scepticism about moral responsibility, so are also, a fortiori, sceptics about moral responsibility for negligence.

¹⁹ More specifically, for gross negligence manslaughter in English law this will be the serious risk of death. It is not entirely clear what “serious” is supposed to add, but I speculate below (see note 42 below).

³⁹ For this criticism, see Law Commission, Legislating the Criminal Code: Involuntary Manslaughter (Law Com. No. 237, 1996), at [3.9]. This criticism has, however, been rejected by the Court of Appeal: see Misra [2004] EWCA Crim 2375, at [58]–[62]. Nevertheless, it is not clear the court's response is convincing (see e.g. Ormerod and Laird, Smith and Hogan's Criminal Law, 594), and we should, at the very least, avoid giving too great an explanatory role to the grossness requirement.

⁴⁰ In addition, such a doctor is not plausibly grossly negligent in relation to their patient's death, which is required for gross negligence manslaughter, a point I will return to below.

⁴¹ I should note that worries about a capacity-relative negligence standard do not apply to an evidence-relative one. For example, some have worried that a standard relative to all the defendant's shortcomings ceases to be an objective standard (see e.g. Ormerod and Laird, Smith and Hogan's Criminal Law, 136–38; cf. Honoré, T., Responsibility and Fault (Oxford 1999), 33–34Google Scholar; for a response, see Simester et al., Simester and Sullivan's Criminal Law, 169–74). One also might have a more practical worry that it is difficult to know whether or not someone had the capacity to recognise risk. Neither worry applies to an evidence-relative test. An evidence-relative test is clearly still objective. And given we are assuming that a fact is in one's evidence if one knows it, one can know a defendant's evidence if one knows what they know, something the criminal law accepts can be proven in other contexts.

⁴² The courts have not defined what “serious” is supposed to mean, and how it is distinct from “obvious”. But it is natural to read “serious” as denoting that the risk is above a certain threshold of likelihood in some objective but non-evidence-relative sense of probability. To illustrate, Marie Curie's exposure to radiation created a serious risk to her health and her life, but one that was not obvious given what was known at the time.
