Summary

Article 12(2) of the Convention on the Rights of Persons with Disabilities requires the recognition that persons with disabilities enjoy legal capacity on an equal basis with others in all aspects of life. Such acknowledgment implies that state parties to the Convention, including South Africa, will have to reassess their existing legal provisions relating to legal capacity. These legal measures typically include a rule to the effect that where a person accused of a criminal offence lacks criminal capacity as a result of an intellectual or psychosocial disability, he or she cannot be held liable in criminal law (often referred to as the ‘insanity defence’). This article examines the potential influence of the recognition of universal legal capacity in the CRPD on the insanity defence, with specific emphasis on the current position in South African law. It commences with an overview of the normative content of article 12 of the CRPD as it relates to the notion of criminal capacity and also considers the interpretations of this provision as proposed by academic commentators. These interpretations may be described as, first, an abolitionist position (calling for both the elimination of the insanity defence and the concomitant mandatory committal of the accused to forensic psychiatric institutions) and, second, an integrationist position (suggesting the development of disability-neutral rules on criminal capacity). A third approach strongly argues in favour of retaining the insanity defence while at the same time reconsidering the institutionalisation of an accused person following an acquittal based on this defence. The present South African legislative dispensation regarding criminal capacity is subsequently examined and measured against the CRPD. The article concludes with a number of observations in view of potential law reform.

 

1 Introduction

The guarantee of ‘universal legal capacity’ in article 12 of the Convention on the Rights of Persons with Disabilities1 (CRPD) requires state parties to recognise that persons with disabilities enjoy legal capacity on an equal basis with others in all aspects of life. In most jurisdictions this implies a far-reaching overhaul of existing laws.2 South Africa, as party to the Convention,3 is no exception in this regard.

Certain aspects of universal legal capacity, such as the development of supported decision-making mechanisms4 in line with article 12(3), already have generated a burgeoning body of literature,5 especially in light of the interpretive guidelines adopted by the Committee on the Rights of Persons with Disabilities (CRPD Committee). However, one issue that has drawn less attention from academic commentators (and, arguably, from the CRPD Committee itself), is the implications of the CRPD for the concept of ‘fitness of an accused6 person to stand trial’ as well as for the so-called ‘insanity defence’.7

The notion of fitness to stand trial generally refers to the ability of the accused, at the time of the criminal trial, to follow the proceedings, to instruct her legal representative and offer a proper defence.8 Criminal capacity, on the other hand, relates to the question of whether the accused had the ‘mental elements’ necessary to be held responsible,9 such as the ability to appreciate the wrongfulness of her actions at the time of the commission of the offence.10 Both constructs therefore rely on an assessment of the accused’s mental capacity (albeit at different stages).11

A further common element is that in many criminal justice systems, upon a finding of unfitness to stand trial or of criminal incapacity, the court must order a special disposition in respect of the accused. This may include detention until the accused is fit to stand trial; indefinite detention (accompanied by involuntary treatment) in a psychiatric hospital; or diversion to mental health care services. The perceived ’dangerousness’ of the accused (to herself or others) often provides the rationale for such special measures.

The insanity defence has been called into question for its non-compliance with article 12 of the CRPD, specifically in respect of the disregard of the principle of universal legal capacity. The CRPD Committee further has expressed the view that systems of special disposition, which typically permit the detention of persons with psychosocial disabilities based on their disability, constitute a violation of article 14 of the Convention,12 which explicitly states that the existence of a disability under no circumstances justifies a deprivation of liberty.13

The article accordingly interrogates the implications for the insanity defence14 of the recognition of universal legal capacity and the prohibition of disability-based deprivations of liberty. It first provides a brief overview of article 12, with reference to the drafting process and the contents of the article. It then more closely examines the notion of ‘legal capacity’ and also considers the interpretive guidance provided by the CRPD Committee in General Comment 1, adopted in 2014.15 The article further considers different interpretations of the relevant provisions by selected academic commentators. It next turns to the status quo in South Africa in respect of criminal incapacity as a result of psychosocial disability, and attempts to measure the applicable provisions against guidelines provided under the CRPD. Ultimately, the article does not seek to propose definitive solutions, but rather to explore the ‘borderlines’ around the insanity defence (in Perlin’s words),16 thereby providing a basis for future debate.

2 Article 12 of the Convention on the Rights of Persons with Disabilities

2.1 Background

Article 12 has been described as being ‘at the core’ of the Convention17 - an embodiment of the paradigm shift18 inherent in this document.19 The right to equal recognition before the law implies that legal capacity is a universal attribute inherent in all persons by virtue of their humanity which must be upheld for persons with disabilities on an equal basis with others. 20

Not surprisingly, the recognition of legal capacity of persons with disabilities emerged as one of the most controversial areas of debate during the preparatory negotiations of the CRPD.21 A particularly thorny question was whether the term ‘legal capacity’ should be understood to include both the capacity to be a holder22 of rights and the capacity to be an actor under the law.23 The first component, referred to as ‘legal standing’,24 entails being viewed as a person before the law,25 which in turn entitles the person to full protection of her rights by the legal system.26 The second component, known as ‘legal agency’, is the capacity to act on or exercise these rights,27 which involves the recognition of the person as an agent with the power to engage in transactions and create, modify or end legal relationships.28 It is this latter component that is frequently denied or diminished in the case of persons with disabilities.29

Certain delegates to the CRPD negotiations were in favour of a more limited understanding of legal capacity, and attempts accordingly were made to reduce the provisions in article 12 to ‘legal standing’ only,30 which would have lowered the standard of human rights protection in the Convention.31 While the final document as adopted is free of such limitations, it is worth noting that several of the reservations and interpretive declarations subsequently entered by state parties specifically relate to the interpretation of article 12.32

Kanter observes that the history of the drafting process reflects fundamental differences about the ‘very nature of human rights’.33 Significantly, the ‘battles of meaning’34 that arose during the negotiations have continued beyond the adoption of the Convention itself and can still be discerned, for example, in responses to General Comment 1 of the CRPD Committee.35

2.2 Brief overview of contents

Article 12(1) first reaffirms that all persons with disabilities have the right to ‘recognition everywhere as persons before the law’. According to the CRPD Committee, this provision guarantees that every human being is respected as a person possessing legal personality, which is a prerequisite for the recognition of a person’s legal capacity.36 This naturally leads to article 12(2), which states that persons with disabilities enjoy legal capacity on an equal basis with others in all areas of life. The formulation of ’on an equal basis with others’, which also appears in several other articles in the CRPD,37 indicates that the basis of article 12(2) is to be found in equality and non-discrimination.

The unequivocal point of departure here is that all persons with disabilities have full legal capacity, in the sense of both legal standing and legal agency, on an equal basis with others.38 Significantly, this premise is neither conditional (‘all persons have legal capacity provided that they have the capacity to ...’) nor presumptive (‘all persons are presumed to have legal capacity until proved otherwise’).39

Article 12(3) recognises that state parties have an obligation to provide persons with disabilities with access to support in the exercise of their legal capacity. The approach required in terms of the CRPD is that instead of denying persons with disabilities their legal capacity, states must rather provide access to the support necessary to make decisions that have a legal effect.40 ‘Support’ is a broad term encompassing both informal and formal support arrangements, of varying types and intensity.41

Article 12(4) provides that ‘appropriate and effective safeguards’ must be included in systems supporting the exercise of legal capacity.42 These safeguards must ensure that measures relating to the exercise of legal capacity are proportional and personalised and apply for the shortest time possible. Regular review by a competent, independent and impartial authority or judicial body is also highlighted.

Finally, article 12(5) requires state parties to take all ‘appropriate and effective’ measures to ensure the rights of persons with disabilities with respect to financial and economic affairs, on an equal basis with others.43 The traditional denial of legal capacity regarding matters of finance and property must now instead be replaced with support to exercise legal capacity, in accordance with article 12(3).44

2.3 Interpretation of article 12: General Comment 1

In 2014 the CRPD Committee adopted a General Comment on article 12, aimed at examining the general obligations arising from the different aspects of this article.45 Such general comments by treaty-monitoring bodies are not binding interpretations of the Convention,46 but are nevertheless considered as particularly persuasive interpretations of international law.

Although the content of General Comment 1 is far-ranging, this section will look at one of the aspects most relevant to criminal incapacity, namely, the de-linking of legal capacity from mental capacity. This becomes especially significant when one notes that the comment itself does not directly address criminal capacity as such.47

2.3.1 Separation of legal capacity and mental capacity

According to the CRPD Committee it must be clearly understood that legal capacity and mental capacity are separate concepts.48 Legal capacity, on the one hand, consists of the ability to hold rights and duties and to exercise those rights and duties. Mental capacity, on the other, refers to decision-making skills, which naturally differ from one person to another, depending on many factors such as environmental and social factors. Mental capacity49 is not, as is commonly presented, an ‘objective, scientific and naturally occurring phenomenon’.50 Instead, it is dependent on many factors, including social and political contexts.51

Article 12 makes it clear that ‘unsoundness of mind’ and other discriminatory labels are not legitimate reasons for the denial of legal capacity.52 Under this article perceived or actual deficits in mental capacity may not be employed to justify a negation of legal capacity.53 The CRPD Committee observed that in most of the state party reports that it had examined, the concepts of mental and legal capacity had been merged so that where a person is considered to have impaired decision-making skills (often because of a cognitive or psychosocial disability), his or her legal capacity is removed as a result thereof.54

Considering the three established methods for assessment of legal capacity, namely, the status approach,55 the outcome approach56 and the functional approach,57 the Committee points out that all three approaches regard a person’s disability and/or decision-making skills as legitimate grounds for denying legal capacity and ‘lowering his or her status as a person before the law’.58 Such discriminatory disavowal of legal capacity is not permitted under article 12.59 Importantly, the provision of support to exercise legal capacity should not depend on mental capacity assessments. Instead, the Committee recommends that ‘new, non-discriminatory indicators of support needs’ are necessary.60

2.3.2 Responses to General Comment 1: Unfinished business?

The CRPD Committee in General Comment 1 takes a robust and principled stance in respect of contentious areas such as supported decision making and involuntary treatment. For example, it confirms that the human rights-based model of disability demands a shift from the framework of substitute decision making (which includes practices such as guardianship) to one that is based on supported decision making.61 The Committee accordingly discerns an obligation on state parties to replace substitute decision-making regimes by support for decision making that respects the person’s autonomy, will and preferences.62

Despite this clear pronouncement, there still appears to be some lingering questions as to whether substitute decision-making systems are permitted under the CRPD. For example, Freeman et al suggest that the ‘universal presumption of legal capacity’ and the pre-eminence of supported decision making cannot be absolute and that exceptions have to be considered.63

Similarly, despite the Committee’s clear normative directives, disparate views remain on the permissibility of involuntary treatment. For example, Szmukler et al suggest that ‘very few would support the idea that the state never, even as a last resort, has a duty to protect those who are clearly unable to make crucial treatment decisions for themselves’.64

General Comment 1 thus exposes the fault lines between those who accept the premise of ‘universal legal capacity with support’, irrespective of whether the person requires more intensive support,65 and those who would reserve an exception (albeit limited) in respect of persons who are regarded as unable to act, even with the benefit of support - who are, in the words of Slobogin, ‘too impaired to allow them to make a decision’.66 These tensions and divisions also become apparent when considering criminal capacity and psychosocial disability, as will be shown below.

3 Criminal capacity and the Convention on the Rights of Persons with Disabilities

3.1 Guidance from the CRPD Committee

As explained above, the insanity defence is not directly addressed in General Comment 1 itself. However, the implications of universal legal capacity for this defence were considered as early as 2009 in the thematic report of the Office of the High Commissioner for Human Rights (OHCHR), which states:67

In the area of criminal law, recognition of the legal capacity of persons with disabilities requires abolishing a defence based on the negation of criminal responsibility because of the existence of a mental or intellectual disability. Instead disability-neutral doctrines on the subjective element of the crime should be applied, which take into consideration the situation of the individual defendant.

This interpretation subsequently has been developed by the CRPD Committee’s adoption in 2015 of guidelines to provide clarification on article 14 of the Convention.68 These guidelines do not address the recognition (or not) of the insanity defence as such, but do speak to dispositions of detention following an insanity-based acquittal.

The Committee points out that, according to article 14, no exceptions are allowed in terms of which persons may be detained on the grounds of their actual or perceived impairment. The legislation of several state parties still provides for the detention of persons with disabilities on the grounds of their actual or perceived impairment, provided that there are other reasons for their detention, such as the fact that they are deemed dangerous to themselves or others.69 Such legislative provisions are incompatible with article 14, are discriminatory in nature and amount to an arbitrary deprivation of liberty.70 This prohibition also holds implications for involuntary treatment in the course of the deprivation of liberty: The Article 14 Guidelines note that treatment should be based on the free and informed consent of the person concerned.71

As far as declarations that persons with disabilities are incapable of being found criminally responsible and the concomitant detention of such persons are concerned, the Committee notes that these practices are contrary to article 14, since they deprive the person of the right to due process and safeguards applicable to every accused person.72 State parties accordingly are enjoined to remove such declarations of criminal incapacity from their criminal justice systems.73

The Committee also deals with security measures (such as involuntary treatment in institutions) imposed on persons found not responsible due to criminal incapacity74 and recommends the elimination of such measures. Similarly, it is concerned about security measures that involve indefinite deprivation of liberty and the absence of regular rights guarantees in the criminal justice system.75

When it comes to the deprivation of liberty in criminal proceedings, the Committee recommends that this should apply only as a matter of last resort and when other diversion programmes, including restorative justice, are insufficient to deter future crime.76 Specifically, diversion programmes must not involve a transfer to mental health commitment regimes or require an individual to participate in mental health services, but should instead be provided on the basis of the individual’s free and informed consent.77

The Committee’s views, as expressed in General Comment 1 and the Article 14 Guidelines, have drawn divergent responses from academic commentators. In the next section the opinions of three authors, canvassing a range of considerations, are examined.78

3.2 Interpretation by commentators
3.2.1 The abolitionist position: Elimination of the insanity defence

Minkowitz regards all measures by which persons with disabilities are treated unequally in legal proceedings, including the insanity defence, as well as a disposition to forensic psychiatric institutions, as disability-based discrimination and, accordingly argues for the elimination of such measures.79

She first relies on a direct reading of the recognition in article 12(2) of equal legal capacity in all aspects of life, which clearly has to include criminal matters. Furthermore, if persons with disabilities have the legal capacity to act on an equal basis with others, this capacity logically extends to all circumstances ‘where decisions have consequences’, which implies legal responsibility for those consequences on an equal basis with others.80 She also notes that the rejection by the CRPD Committee in General Comment 1 of attaching legal or practical consequences to the assessment of mental capacity, logically precludes the use of mental capacity assessments to negate criminal responsibility.81

A denial of criminal responsibility based on mental incapacity as an evaluative concept constitutes disability-based discrimination and impairs the right to equal recognition before the law by giving legal effect to such incapacity and stigmatising the particular individual as well as all persons with psychosocial and intellectual disabilities.82

She finds further support in article 14(1) of the CRPD, which (as noted above) provides that the existence of a disability in in no case may justify a deprivation of liberty. Mental health detention, which by definition is premised on apparent psychosocial disability or a psychiatric diagnosis, can never be disability-neutral and, therefore, always violates article 14(1).83

Minkowitz develops a proposal for ’inclusive design of criminal responsibility’.84 As a starting point the court must, as part of the finding of intent (that is, the subjective element of a criminal offence) consider the perceptions, beliefs and world view of the accused with respect to her actions at the time of the relevant act, to the extent that such evidence is available.85 However, this does not amount to an assessment of mental capacity, but rather is an ‘open-ended inquiry into ... contextualising factors that can help to make sense of a person’s actions’.86 If there is a lack of proof of criminal intent or any other element of the crime, the result would be an acquittal or a reduction of the degree of culpability without reference to mental capacity.87

In terms of this proposal there would be no insanity defence or concept of mental incapacity.88 At the same time an acquittal or conviction would not result in detention in a forensic mental health institution or other special security-related measure. If the accused is found guilty, she would serve her sentence in an ordinary place of detention, under the same conditions as others, subject to reasonable accommodation and in compliance with the other principles of the CRPD.89

3.3.2 The integrationist position: Developing disability-neutral rules

As a response to the ‘tough normative and practical questions’90 presented by the CRPD, Slobogin proposes a three-fold model based on the punitive, preventive and protective approaches to deprivation of liberty.91 These three approaches can briefly be explained as follows.

The goal of the punitive approach, which focuses on culpability, is to punish people for the harm they have caused.92 The deprivation of individual liberty, therefore, is permitted if the person has caused harm to another person or their property in a culpable manner. The preventive approach aims to prevent harm to others and, therefore, focuses on perceived dangerousness.93 This approach to liberty deprivation is permitted only when the benefits of such deprivation outweigh the harm caused. The goals of the protective model include the promotion of autonomy and the protection of dignity through self-determination.94 Examples are guardianship and hospitalisation of an accused person to ‘improve’ their ability to participate in the criminal proceedings.95

Slobogin then explores how the aims of the CRPD may be accomplished in respect of each model.96 Regarding punishment he posits that the CRPD Committee’s call for elimination of a ‘special’ defence of insanity is in line with his integrationist approach to criminal law, which holds that persons with psychosocial disabilities may rely on any of the defences that are available to accused persons generally.97

Slobogin distinguishes a general trend (in the United States (US) and other countries) towards a more subjective approach to culpability, which entails that the accused’s blameworthiness is assessed according to her actual desires and beliefs, rather than with reference to what a reasonable person would have desired or believed.98 For example, virtually all

criminal offences in the Model Penal Code99 require proof that the accused ‘purposefully or knowingly’ caused the harmful conduct,100 which exemplifies this trend towards the subjectification of mens rea. The defences of self-defence, provocation and duress likewise are subjectified under the Code; for example, the use of deadly force is permitted where the actor (subjectively) believes that this is immediately necessary to protect herself against unlawful force.101

Slobogin explains that granting people with psychosocial disability a ‘special defence’ stigmatises102 and marginalises them. The category of ‘criminal insanity’ also perpetuates the deleterious myth that people with psychosocial disabilities are particularly dangerous or lack self-control. Maintaining that compared to an acquittal by reason of insanity, exoneration on the grounds of lack of intent, self-defence, or duress is far less tainting,103 he accordingly formulates a ‘disability-neutral’ defence’, which would apply equally to all persons, irrespective of psychosocial disability. One potentially contentious aspect of this defence is that it would not be available where the ‘impairments’ that led to the accused’s erroneous beliefs resulted from the accused’s purposeful avoidance of treatment.104

In respect of the prevention model, Slobogin reiterates that the detention of persons with psychosocial disabilities on the grounds of ‘dangerousness’ is viewed as discriminatory and in violation of the prohibition of disability-based deprivation of liberty in terms of the CRPD. The legal basis for such deprivation accordingly must be de-linked from disability and be neutrally defined so as to apply to everyone on an equal basis.105 He thus argues for a general prohibition of preventive detention or other measures aimed at protecting others. However, this would be subject to one exception, namely, cases where the criminal justice system cannot function as a preventive mechanism because first, it lacks jurisdiction (for example, where the accused has been acquitted or has completed serving her sentence) and, second, because the person is ‘truly undeterrable’.106

The notion of undeterrability would include two categories of people with psychosocial disabilities: those who cause harm in the delusional belief that they are not committing a crime; and those ‘with urges so strong’ that they tend to commit crime despite a high risk of apprehension and punishment. These two groups are unaware of the possibility of punishment and thus are truly undeterrable.107 In order to demonstrate that this formulation of undeterrability is disability-neutral, Slobogin identifies two other categories of people that would be regarded as undeterrable, namely, persons with contagious diseases and ‘enemy combatants’.108

3.3.3 The third position: Retaining the insanity defence

In a strongly-worded article Perlin takes the position that to deprive persons with psychosocial disabilities109 of the right to plead insanity demeans any notion of dignity.110 He believes that the insanity defence plays a critical role in a fundamentally-fair criminal justice system; discarding it would violate the most basic principles of due process111 as well as the fundamental notion that only people who are responsible for their actions should be punished.112 The exculpation of some individuals based on their mental state is essential to a mature and coherent system of criminal law.113 Therefore, he is of the opinion that the proposed abolition of this defence is ‘wrongheaded, counterproductive and likely a violation of due process’.114

In respect of Slobogin’s proposals for recasting the insanity defence, Perlin is of the opinion that the revised disability-neutral version still amounts to the insanity defence; it is just not characterised as such.115 He is also sceptical of the clause providing that the defence should not be available to an accused person who caused her own mental state (for example, by refusal of treatment).116 He expresses concern that this proviso will be used ‘broadly and bluntly’ to suppress the right to refuse involuntary administration of antipsychotic medication (which is otherwise protected by the CRPD and domestic law).117

Perlin also responds to Minkowitz’s position. As a preliminary point he is in agreement with her that the insanity defence, as currently utilised, often is legally and socially stigmatising; that acquittals on the grounds of insanity often do not result in release from custody; and that persons found not guilty by reason of insanity often are held in forensic facilities for far longer than is warranted by the underlying criminal offences with which they were originally charged.118 However, these realities do not justify the abolition of the insanity defence: The abuses (correctly) listed by Minkowitz are not caused by the defence in itself, but rather by the administration of the system of ‘post-insanity-defence-acquittal’ case dispositions and institutionalisation; hence, this is where the attention should instead be focused.119

For Perlin the major question is what will happen to this ‘cadre of defendants’ in the absence of an insanity defence. He predicts that the immediate result of the abolition of the insanity defence would be the long-term incarceration of this group in prisons that are known to be dangerous and life-threatening to them.120

Ultimately he finds no demand for the abolition of the insanity defence in the CRPD (including article 14).121 Instead, he believes that when the CRPD is read as a whole (together with other international human rights instruments requiring fair trials), it in fact calls for its retention.

3.3.4 Discussion

Although the views of the three authors as presented here appear to diverge in several respects, at the same time there are significant points of agreement. First, one cannot fault Minkowitz for her reading of articles 12 and 14, as underpinned by General Comment 1 and the Article 14 Guidelines (although Perlin clearly disagrees).

Regarding the disposition of the accused following an acquittal: Again, Minkowitz’s view that this should not be followed by detention in a forensic mental health system (or other involuntary measure) is in line with the CRPD Committee’s interpretation. However, the notion that persons with psychosocial disabilities who are convicted of criminal offences should serve their sentences under the same conditions as others indeed raises the major concerns pointed out by Perlin. This may well be an instance where formal equality (treating all convicted persons in the same way) may have to yield to considerations of substantive equality that takes account of material differences.

Minkowitz’s proposal for inclusive design of criminal responsibility in many respects resembles Slobogin’s integrationist approach. The focus on the subjective elements of intent, requiring an assessment of the accused’s blameworthiness according to her actual beliefs and desires, rather than a ‘reasonable person’ standard, combined with a subjective approach to established defences such as self-defence and duress, certainly holds promise for developing a ‘disability-neutral defence’ that moves away from the insanity defence.122 Furthermore, the question of whether this defence should be available where the state of mind of the accused is the result of failure to comply with treatment should be resolved. (Perlin’s reservations in this regard are well-founded.)

In terms of preventive detention, Slobogin suggests a narrow, disability-neutral allowance, based predominantly on the notion of undeterrability. Apart from any other concerns (such as the construction of ‘undeterrability’), the purported neutrality of this proposal is dubious. Although its formulation would also include certain persons without psychosocial disabilities, such as ‘enemy combatants’, such a measure would disproportionately affect persons with psychosocial disabilities, thus offending against the prohibition of indirect discrimination.123

4 South African law

Against this background the following section briefly examines certain aspects of the current South African legal position. First, the general principle regarding legal capacity is set out, followed by the statutory provisions dealing with criminal incapacity based on psychosocial disability. The implementation of section 78 is then briefly considered and, in conclusion, the current position is evaluated against the considerations outlined in section 3 above.

4.1 General principles

In terms of South African law generally, every person above 18 years of age may exercise legal capacity to its fullest extent, which means that she may by herself and without the assistance or consent of any other person exercise all the rights and become subject to all the duties associated with being a ‘person’.124 However, the legal capacity of persons that are ‘insane or mentally disordered’ is limited.125 These limitations, as they relate to criminal capacity, are dealt with in section 78 of the Criminal Procedure Act 51 of 1977 (CPA). Section 78 will be examined briefly by looking at the substantive issue of criminal incapacity due to mental illness126 as well as the prescribed disposition by the court on finding that the accused lacks criminal capacity.

4.2. Statutory provisions

In South African law the point of departure is that criminal capacity, which is regarded as the basis of (and general precondition for) culpability,127 may be excluded by a number of grounds, including youthfulness,128 intoxication and mental illness. In respect of the latter the test to determine the accused’s criminal capacity is set out in section 78(1) of the CPA. This section provides that a person committing an offence, while at the time suffering from a ‘mental disorder or intellectual disability’129 which makes her incapable (a) of appreciating the wrongfulness of her act; or (b) of acting in accordance with such an appreciation, will not be ‘criminally responsible’.

The defence of criminal incapacity due to mental illness usually is raised on behalf of an accused at the beginning of the trial (at the stage of pleading to the charges). Where incapacity is alleged, the accused must be dealt with in terms of section 79 of the CPA, which regulates the process of inquiry into the accused’s (in)capacity and the subsequent process of reporting to the court.130

Upon completion of the prescribed inquiry and submission of the experts’ reports131 in terms of section 79, the court must make a finding regarding the accused’s criminal capacity.132 If the court finds that the accused committed the act in question and that she at the time of commission lacked criminal capacity, she must be found not guilty by reason of mental illness.133 For purposes of the criminal prosecution, the matter ends there: The accused has been found not guilty and cannot again be charged with the same offence. However, this is not the end for the accused: The court must now direct an outcome, depending on the nature of the charges against the accused.

First, if the accused has been charged with murder, culpable homicide, rape or compelled rape,134 or a charge involving serious violence, or if the court considers it necessary in the public interest, the court may order her detention in a psychiatric hospital.135 This is subject to the decision of a judge in chambers in terms of section 47 of the Mental Health Care Act (MHCA).136 The court may alternatively order that the accused be detained in a designated health establishment as if she was an involuntary mental health care user as set out in section 37 of the MHCA;137 be released with or without conditions; or referred to a children’s court, in the case of a child.138

Second, where the accused is charged with an offence other than the ones listed above, that is, a less serious offence, the court may order that the accused be detained as an involuntary mental health case user (as above); released with or without conditions; or referred to a children’s court.139

Importantly, for proceedings in terms of sections 77(1)140 and 78(2) the court may order that the accused be provided with the services of a legal representative,141 if the court is of the opinion that substantial injustice would otherwise result.142

4.3 Determination of criminal capacity in terms of section 78

In order to establish the criminal capacity of the accused, the court must as a point of departure determine whether the accused had been suffering from a mental illness. If so, the second step is to establish the impact of such mental illness at the time of the commission of the offence. Notably, the CPA does not provide a definition for mental illness (or intellectual disability). The MHCA, on the other hand, defines ‘mental illness’ in terms of a positive diagnosis, made by an authorised mental health care practitioner on the basis of accepted diagnostic criteria, of a ‘mental health-related illness’.143 However, this definition is not conclusive in respect of a criminal trial: The fact that the accused has been diagnosed with a mental illness in terms of the MHCA does not mean that he is also ‘mentally ill’ for purposes of the CPA. 144

Due to this lack of a definition of ‘mental illness’ in the CPA, psychiatric evidence is regarded as indispensable in the determination of criminal capacity. This was confirmed in S v Mabena,145 where the Supreme Court of Appeal explained that a lay court cannot diagnose a ‘mental illness’ without guidance by expert psychiatric witnesses.146 Having said that, the final decision as to the accused’s criminal capacity, including the assessment of the experts’ reports and other evidence, lies with the court.147

4.4 Evaluation

For purposes of this discussion, it is helpful to return to the two aspects of the insanity defence, namely, the finding of criminal incapacity (and hence acquittal) in respect of the accused due to mental illness, and the subsequent disposition by the court.

In terms of the finding that the accused lacks criminal capacity it should be noted that the grounds for excluding criminal capacity under South African criminal law extend beyond mental illness to also include youthfulness and intoxication. The special measures relating to the inquiry into the accused’s criminal capacity as set out in the CPA (namely, the referral for observation and the reports by experts), however, are applicable only to persons with a mental illness. Similarly, the disposition measures following a finding of not guilty by reason of mental illness only operate here. Accordingly, this constitutes differential treatment of accused persons with psychosocial disabilities. However, such differentiation does not in itself necessarily amount to ‘unfair discrimination’ as understood in South African constitutional jurisprudence.148

The measurement against the South African Constitution becomes necessary at this point because of the fact that the CRPD has not yet been formally ‘incorporated’ into South African law as required in terms of section 231 of the Constitution. However, courts are required to consider the Convention as an interpretive aid when interpreting the Bill of Rights.149 The judgment of the Constitutional Court in De Vos NO v Minister of Justice and Constitutional Development150 exemplifies such invocation of the CRPD.151

In addition to the discrimination-based argument alluded to above, it should be noted that the assessment of criminal incapacity arising from mental illness under section 78 of the CPA in essence is a functional test (resting on proof of incapacity to appreciate the wrongfulness of an act or to act in accordance with such an appreciation). It also amounts to the conflation between legal capacity and mental capacity cautioned against by the CRPD Committee in that the accused person’s legal capacity is ‘removed’ because of a finding that her decision making was impaired at the time of the offence.152 These considerations further complicate the insanity defence in its current form.

Significantly, in terms of South African criminal law, the test for intention is subjective, which means that the accused’s individual characteristics, personal beliefs, background and psychological disposition may be taken into account in determining whether or not she had the required intention.153 Intention, therefore, may be excluded, for example, by so-called ‘putative private defence’ (where the accused erroneously believes that an unlawful attack is being directed at her, and she therefore acts to ward off this attack). Since unlawfulness is determined objectively, her defensive act would be unlawful - because in reality there was no attack against her - but her honest mistake as to the existence of an attack may exclude intention.154

Such a mistake does not need to be reasonable: The inquiry concerns the accused’s ‘true state of mind’ and her conception of the circumstances, and not whether the reasonable person in the accused’s position would have made the same mistake.155 This subjective construction of intent theoretically opens the door for the consideration of a disability-neutral defence, such as mistake, on the part of the accused, since the source and reasonableness of such mistake would not be at issue.

With regard to the second aspect, namely, disposition of the accused on conclusion of the criminal case, Kaliski points out the anomaly that (former) accused persons committed to the forensic mental health system following an acquittal by reason of mental illness, often face indefinite detention while convicted offenders may serve only a part of their sentence based on remittances for good behaviour and other concessions.156

Noting the ‘largely failed enterprise of risk assessment’, Kaliski also questions the concept of ‘dangerousness’ associated with mental illness and the assumption that indefinite detention at least addresses the risk of future violence.157 (‘Dangerousness’ comes into play in the court’s determination of whether detention as a state patient in a psychiatric hospital is required ‘in the public interest.’158)

Were the South African courts to follow the principled view of the CRPD Committee that disability-based detention violates the right to liberty of persons with psychosocial disabilities under article 14, this would cast a dark shadow over the current provisions of section 78(6). It should, however, be noted that a rights violation may be justified under the ‘limitations clause’ (section 36) of the Constitution, and it is conceivable that a court would weigh up the detainee’s right to liberty against the state’s duty to protect the public from harm.159

Finally, one aspect that needs further consideration is the provision of support, in terms of article 12(3), where the accused’s criminal capacity is at issue (although this arguably relates more to situations where the accused may be unfit to stand trial).160 Section 77(1B) of the CPA, which permits the court to order the appointment of a legal representative for the accused, is a good starting point. However, at present such appointment is discretionary whereas, it is argued here, it should be mandatory in all cases where the fitness to stand trial or criminal capacity of the accused is in dispute.161 Other analogies of support may be drawn from the current arrangements regarding the role of a curator ad litem.162

5 Conclusion

Peay correctly observes that thinking through the implications of the CRPD for criminal liability is not easy.163 This in part is due to the fact that the CRPD has introduced dramatic changes into areas of law ‘that had previously been thought settled’.164 As outlined above, this certainly includes the insanity defence.

It is encouraging that the South African government has committed itself to a review of civil and criminal legislation, including the inquiry into an accused person’s criminal capacity in criminal proceedings, in light of article 12 of the CRPD.165 It is argued here that close consultation with and the active involvement of persons with disabilities166 (especially those with psychosocial disabilities and forensic detainees)167 will be essential in any consideration of law reform measures.

Petersen expresses doubt as to whether legislatures would ever accept proposals for the complete abolition of the insanity defence168 and, therefore, cautions that it may be more practical to consider reforms to current defences and to provide stronger safeguards (including more regular reviews of the disability-related detention of accused persons).169 One has to agree that the abolition of the insanity defence would be hard to ‘sell’ in the current South African context.170

However, this does not obviate the need to develop practicable (and politically-feasible) alternatives to guide incisive domestic law reform.171 This is especially true in relation to ‘an entirely novel approach for which there is often no precedent elsewhere’.172 Such recommendations are essential in order for the reassurances in the CRPD to ultimately transcend from the aspirational to the tangible.

47. General Comment 1 indirectly refers to the inter-connection between legal capacity and access to justice (art 13), which entails that in order to enforce their rights and obligations on an equal basis with others, persons with disabilities must be recognised as persons before the law with equal standing in courts and tribunals (para 38).

49. De Bhailís & Flynn (n 24) 10 point out that the term ‘mental’ capacity is used to refer to a ‘combination of cognitive ability, impairment and a person’s extent of understanding of the consequences of their actions’. An example of the use of mental capacity as a means to assess and deny legal capacity is found in legislation that establishes a test of mental capacity as the necessary precondition for making certain legally-binding decisions, such as decisions about consent to medical treatment.

57. This involves the consideration of legal capacity on an issue-specific basis. Eg, a person might not be able to make decisions of a financial nature but might be considered to have capacity to consent to an intimate relationship; CDLP (n 17). Legislation based on the functional approach typically requires that the person must be able to use, weigh and retain the information necessary to make the decision, to understand the consequences of their decision and to communicate her decision to others.

125. Terminology in the original text.

126. Due to its use in the CPA, the term ‘mental illness’ is employed in this section for purposes of clarity. It should, however, be noted that mental illness is not the conceptual equivalent of ‘psychosocial disability’.

127. Culpability, also sometimes referred to as mens rea, means that there must, in the eyes of the law, be grounds for blaming the accused personally for her unlawful conduct; C Snyman Criminal law (2014) 156. South African criminal law recognises two forms of culpability, namely, intention and negligence.

128. See sec 7 of the Child Justice Act 75 of 2008.

129. This provision previously referred to ‘mental defect’; however, in 2017 the term was replaced by ‘intellectual disability’.

130. For purposes of this inquiry, the court may commit the accused to a psychiatric hospital or to any other designated place for a period not exceeding 30 days (sec 79(2)(a)).

131. Sec 79 sets out the composition of the panel that has to conduct the inquiry (which varies based on the seriousness of the offence) and stipulates what must be contained in the report. Where the accused is charged with a more serious offence, the panel must consist of three psychiatrists and the court has the discretion to also appoint a clinical psychologist (sec 79(1)(b)).

132. Sec 78(6).

133. Or intellectual disability, as the case may be (sec 78(6)).

134. As set out in secs 3 & 4 of the Criminal Law (Sexual Offences) Amendment Act 32 of 2007.

135. Sec 78(6)(a)(i)(aa). Alternatively, the court may order temporary detention in a correctional health facility pending the availability of a placement in a psychiatric hospital, if the court is of the opinion that it is necessary to do so on the grounds that the accused poses a serious danger or threat to herself or to members of the public (sec 78(6)(a)(i)(bb)).

136. Act 17 of 2002. The accused therefore becomes a so-called ‘state patient’ in terms of MHCA. Among other implications, this means that she may indefinitely be detained in a designated health establishment and may only be discharged (released) from detention by order of a judge in chambers.

137. An ‘involuntary mental health care user’ in terms of the MHCA is a person incapable of making informed decisions due to her mental health status, who refuses health intervention but requires such services for her own protection or for the protection of others. Sec 37 provides for the periodic review of the mental health status of an involuntary mental health care user, which must include the consideration of whether the mental health care user is likely to inflict serious harm to herself or other people (sec 37(2)(b)).

See also S v Chauke 2016 (1) SACR 408 (SCA) para 17. Kaliski, however pours cold water on this enthusiasm for assistance from psychiatry in assessing criminal capacity, noting, first, the fluidity of psychiatric diagnoses and, second, his misgivings about an ‘appreciation of wrongfulness’ as determinant of criminal responsibility; S Kaliski ‘Does the insanity defence lead to an abuse of human rights?’ (2012) 15 African Journal of Psychiatry 85.

149. Sec 39(1)(b) Constitution.

150. 2015 (2) SACR 217 (CC). This matter dealt with the disposition of two accused persons following a finding of ‘unfitness to stand trial’ in terms of sec 77(6). The previous version of this subsection, prior to amendment in 2017, allowed the court a narrower range of options for disposition and specifically excluded the release of the accused (with or without conditions). The difficulty that arose here was that the two accused persons were diagnosed with intellectual disabilities, and the expert opinion was that their (in)ability to stand trial would not ‘improve’ upon detention in a prison or psychiatric hospital. The Constitutional Court ultimately held that the provisions limiting the court’s options were inconsistent with art 12 of the Constitution (the right to liberty and security of the person) as read with art 14 of the CRPD. This resulted in the subsequent amendment of the CPA by the Criminal Procedure Amendment Act 4 of 2017.

151. Paras 29-30, 58.

152. See sec 2.3.1 above.

153. The test for negligence, on the other hand, is objective: The conduct of the accused is measured by the standard of what a reasonable person in the accused’s position would have done under the same circumstances. Negligence usually is regarded as the less serious or blameworthy form of culpability.

154. See S v De Oliveira [1993] 2 All SA 415 (A) 419. The court may however consider the reasonableness of the accused’s conduct in determining whether she did indeed have an honest belief that she was being attacked.

155. As above.

158. The term ‘public interest’ is not defined in the CPA; however, it is conceivable that the potential ‘dangerousness’ of the accused would play a role here.

159 It was held in Carmichele v Minister of Safety and Security 2001 (4) SA 938 (CC) para 57 that the state’s duty under sec 7(2) of the Constitution to respect, protect, promote and fulfil the rights in the Bill of Rights includes the right of the public to have its safety and

159. security protected. The court in the De Vos judgment took specific note of this aspect (para 35). At the same time, however, it may be said that persons with disabilities should not bear ‘the burden of society’s demand for preventive detention’; Minkowitz (n 35) 456.

160. See in this regard Minkowitz (n 35) 446-447.

161. In S v Matu 2012 (1) SACR 68 (ECB) para 28 the court noted that where the accused is charged with an offence involving serious violence, and is hence potentially subject to the more restrictive disposition orders required under sec 77(6)(a)(i), ‘legal assistance is not only desirable but necessary’. Although the judgment related to unfitness to stand trial, it is argued here that it similarly applies in cases of criminal incapacity based on mental illness.

162. A curator ad litem is traditionally appointed by the court to supplement a person’s ‘lack of capacity to litigate’; South African Law Reform Commission (SALRC) Discussion Paper 105: Assisted decision-making of adults with impaired decision-making capacity (2004) 51.
