Decision-Making Capacity First published Tue Jan 15, 2008; substantive revision Fri Aug 14, 2020 In many Western jurisdictions the law presumes that adult persons, and sometimes children that meet certain criteria, are capable of making their own medical decisions; for example, consenting to a particular medical treatment, or consenting to participate in a research trial. But what exactly does it mean to say that a subject has or lacks the requisite capacity to decide? This question has to do with what (...) is commonly called “decisional capacity”, a central concept in health care law and ethics, and increasingly an independent topic of philosophical inquiry. -/- Decisional capacity can be defined as the ability of subjects to make their own medical decisions. Somewhat similar questions of capacity arise in other contexts, such as capacity to stand trial in a court of law and the ability to make decisions that relate to personal care and finances. However, the history behind the more general legal notions of capacity to stand trial and capacity to manage one’s life is different and operates somewhat differently in law (Roth, Meisel, & Litz 1977; Zapf & Roesch 2005). For the purposes of this discussion the notion of decisional capacity will be limited to medical contexts only; most notably, those where decisions to consent or to refuse treatment or participation in clinical research are concerned.

Editorial introduction to series of papers resulting from a European Commission Project on mental capacity.

In many Western jurisdictions, the law presumes that adult persons, and sometimes children that meet certain criteria, are capable of making their own health care decisions; for example, consenting to a particular medical treatment, or consenting to participate in a research trial. But what exactly does it mean to say that a subject has or lacks the requisite capacity to decide? This last question has to do with what is commonly called “decisional capacity,” a central concept in health care law (...) and ethics, and increasingly an independent topic of philosophical inquiry.

In their article “Three Kinds of Decision-Making Capacity for Refusing Medical Interventions,” Navin et al. (2022) argue that we should recognize two forms of decision-making capacity (DMC) besides...

In light of the variety of uses of the term autonomy in recent bioethics literature, in this paper, I suggest that competence, not being as contested, is better placed to play the anti-paternalistic role currently assigned to autonomy. The demonstration of competence, I will argue, can provide individuals with robust spheres of non-interference in which they can pursue their lives in accordance with their own values. This protection from paternalism is achieved by granting individuals rights to non-interference upon demonstration of (...) competence. In this paper, I present a risk-sensitive account of competence as a means of grounding rights to non-interference. On a risk-sensitive account of competence individuals demonstrate their competence by exercising three capacities to the extent necessary to meet a threshold determined by the riskiness of the decision. These three capacities are the capacity to acquire knowledge, use instrumental rationality, and form and revise a life plan. (shrink)

If a person is competent to consent to a treatment, is that person necessarily competent to refuse the very same treatment? Risk relativists answer no to this question. If the refusal of a treatment is risky, we may demand a higher level of decision-making capacity to choose this option. The position is known as asymmetry. Risk relativity rests on the possibility of setting variable levels of competence by reference to variable levels of risk. In an excellent 2016 article inJournal of (...) Medical Ethics(JME), Rob Lawlor defends asymmetry of this kind by defending risk relativity, using and developing arguments and approaches found in earlier work such as that of Wilks. He offers what we call the two-scale approach: a scale of risk is to be used to set a standard of competence on a scale of decision-making difficulty. However, can this be done in any rational way? We argue it cannot, and in this sense, and to this extent, risk relativity is a nonsense. (shrink)

In this paper, we make the case that a person who is considering or has already made a decision that appears seriously harmful to that person should in some cases be judged incapable of making that...

According to the doctrine of informed consent medical procedures are morally permissible when a patient has consented to the treatment. Problematically it is possible for a patient to consent to or refuse treatment which consequently leads to a decline in her best interests. Standardly, such conflicts are resolved by prioritising the doctrine of informed consent above the requirement that the medical practitioner acts in accordance with the duty of care. This means that patient free choice is respected regardless as to (...) whether her choice leads to a decline in her best interests, since to disrespect patient choice would be an instance of ‘unwarranted’ paternalism. This thesis defends the claim that in cases where patient consent comes into conflict with her best interests, paternalistic interference is in fact justified. The ambition of the thesis is thus twofold: in the first place I argue that the doctrine of informed consent cannot be used as an ethical guarantor for medical decision making. Secondly I will conclude that hard paternalism is justified in medical practice, thereby calling for a reversal of the prioritisation of informed consent procedures over the medical practitioner’s duty of care.

With the waves of reform occurring in mental health legislation in England and other jurisdictions, mental capacity is set to become a key medico-legal concept. The concept is central to the law of informed consent and is closely aligned to the philosophical concept of autonomy. It is also closely related to mental disorder. This paper explores the interdisciplinary terrain where mental capacity is located. Our aim is to identify core dilemmas and to suggest pathways for future interdisciplinary research. The terrain (...) can be separated into three types of discussion: philosophical, legal and psychiatric. Each discussion approaches mental capacity and judgmental autonomy from a different perspective yet each discussion struggles over two key dilemmas: whether mental capacity and autonomy is/should be a moral or a psychological notion and whether rationality is the key constitutive factor. We suggest that further theoretical work will have to be interdisciplinary and that this work offers an opportunity for the law to enrich its interpretation of mental capacity, for psychiatry to clarify the normative elements latent in its concepts and for philosophy to advance understanding of autonomy through the study of decisional dysfunction. The new pressures on medical and legal practice to be more explicit about mental capacity make this work a priority. (shrink)

According to Pickering, Newton-Howes, and Young, the harmfulness of decisions does, and should, factor into determining patients' decisional competence. As they claim, decision-making proces...

On the standard view we assess a person’s competence by considering her relevant abilities without reference to the actual decision she is about to make. If she is deemed to satisfy certain threshold conditions of competence, it is still an open question whether her decision could ever be overruled on account of its harmful consequences for her (‘hard paternalism’). In practice, however, one normally uses a variable, risk dependent conception of competence, which really means that in considering whether or not (...) to respect a person’s decision-making authority we weigh her decision on several relevant dimensions at the same time: its harmful consequences, its importance in terms of the person’s own relevant values, the infringement of her autonomy involved in overruling it, and her decision-making abilities. I argue that we should openly recognize the multi-dimensional nature of this judgment. This implies rejecting both the threshold conception of competence and the categorical distinction between hard and soft paternalism. (shrink)

The law in England allows that both parents and competent minors concurrently have the right to consent to medical treatment of the minor. This means that while competent minors may consent to treatment their refusal of consent does not act as an effective veto of treatment and treatment remains lawful if given with parental consent. This approach has been heavily criticized as inconsistent with the House of Lords decision in the Gillick case and damned as ‘palpable nonsense’. In this article, (...) I examine these criticisms and conclude that, far from being illogical, it is entirely consistent with the essential asymmetry between consent to treatment and refusal of treatment. I examine the two metaphors of keyholders and flak jackets used to explain this approach and I suggest that both have value but only when used in combination. I also explain why, contrary to the criticism, it is consistent with Gillick. (shrink)
