16IntroductionIn Autonomy and Law, Springer Nature Switzerland. pp. 1-5. 2025.How can normative claims be rationally justified if one cannot refer to a given moral world, and any norm established by social practice can be called into question? The only foundation of normative claims seems to be the judgements of the norm addressees themselves. But how can norm addressees be bound by norms that they themselves establish? This is the puzzle of autonomy as self-legislation. It also concerns the normative claim of law, which, moreover, pretends to be authoritative and, thus, …Read more

7Alternative Approaches to BalancingIn Autonomy and Law, Springer Nature Switzerland. pp. 63-77. 2025.Balancing as optimisation seems to be the most rational approach regarding conflicting normative arguments. However, it is not generally accepted, and various other accounts of balancing have been suggested. Alternative accounts of balancing are, in particular, Alexy’s “weight formula”, the idea of satisficing, a theory of prioritisation by ranking instead of optimisation, and a method of specification instead of proportionalism. In addition, the approach of constructive interpretation may be re…Read more

16Normative Legal PluralismIn Autonomy and Law, Springer Nature Switzerland. pp. 175-188. 2025.The model of legal systems with ultimate power within their jurisdiction is challenged by the emergence of a plurality of legal systems, which all claim authority on their own and apply to the same legal cases, for example, national constitutional systems, the European Union, and the system of the European Convention on Human Rights. This development threatens the idea that law could resolve conflicts in a normatively justified way and not by mere political power. The issue, hence, is how the em…Read more

9Epistemic Issues of BalancingIn Autonomy and Law, Springer Nature Switzerland. pp. 79-90. 2025.The balancing of normative arguments aims at determining a priority between the conflicting arguments according to their weight in the particular case. The weight of normative arguments in the particular case depends, on the one hand, on the abstract relative weight of the arguments and, on the other, on the degree of fulfilment or non-fulfilment (interference) of the competing demands that follows from the suggested priority relation. This structure is defined by the model of balancing as optim…Read more

11Balancing as OptimisationIn Autonomy and Law, Springer Nature Switzerland. pp. 47-62. 2025.Reasoning with conflicting normative demands takes the form of balancing. Balancing consists in determining a priority amongst conflicting arguments according to their weight. In law, such arguments are usually called “principles” in the sense of norms that can conflict with each other and figure as reasons for a particular result of the balancing of the competing principles. This core idea of balancing has, however, diverse interpretations. In particular, the conception of autonomous balancing …Read more

11Balancing and InterpretationIn Autonomy and Law, Springer Nature Switzerland. pp. 127-141. 2025.In the model of autonomous reasoning, balancing is the characteristic form of normative argumentation. However, in legal argumentation, it seems complimentary, whilst the usual method is that of interpretation within a syllogistic structure of subsumption and deduction. The issue of legal argumentation is to identify a legally valid norm and then interpret and apply it to a particular case. One starts with a statement of the legal norm to be applied. The interpretation aims not at establishing t…Read more

10Dimensions of LawIn Autonomy and Law, Springer Nature Switzerland. pp. 91-108. 2025.Law as a normative systems requires justification through autonomous reasoning. There seems to be no other way to ground the normative claim of law. Normative validity implies that a norm ought to be recognised, applied, and followed by its addressees. Legal norms, claiming normative validity, hence imply an obligation at least of the law-applying organs to recognise, apply and follow these norms. This obligation can hold only if there is a justification for it, and this justification must be fo…Read more

19Competences and Formal PrinciplesIn Autonomy and Law, Springer Nature Switzerland. pp. 109-126. 2025.Normative competences are a crucial feature of law, but also of autonomy as self-legislation. A normative competence implies the capability to change the normative situation because of an intentional act directed to this change. Competence norms confer such a power to an agent, depending on certain conditions. Legal competences confer the power to change the legal situation. Autonomous morality includes the competence to present normative arguments, thus making them valid as arguments, as well a…Read more

21The Foundation of Fundamental RightsIn Autonomy and Law, Springer Nature Switzerland. pp. 143-159. 2025.The term “fundamental rights” is ambiguous and needs clarification. Fundamental rights must have a special status against positive law, which makes their recognition in some sense necessary and independent from positive legislation. Their validity does not follow from mere positive enactment, but they present requirements to be recognised by positive law. Hence, they are normatively justified by moral arguments, particularly by human rights principles. This implies that positive law cannot dispo…Read more

22Rights BalancingIn Autonomy and Law, Springer Nature Switzerland. pp. 161-173. 2025.Law as a normative system must include human rights principles and the principle of proportionality. Human rights principles follow from the demands of autonomous agents to respect their fundamental interests. The principle of proportionality requires a correct balancing of competing normative arguments. Recognition of these principles hence presents a minimal requirement of the protection of human rights or fundamental rights. In this view, rights are connected with interests, that is, with dem…Read more

12Autonomous Reasoning RevisitedIn Autonomy and Law, Springer Nature Switzerland. pp. 7-25. 2025.This essay explores the idea of moral autonomy as self-legislation and presents the model of autonomous reasoning as an account of the rational justification of normative judgements. Autonomy is defined as the balancing of competing normative arguments, all of which are valid and applicable in a situation of conflict. Normative arguments are understood as demands presented and balanced by autonomous agents. Normative judgements resulting from the balancing of normative arguments propose certain …Read more

11Law and MoralityIn Autonomy and Law, Springer Nature Switzerland. pp. 189-204. 2025.The normativity of law must be founded on autonomous reasoning. Hence, a crucial issue of a theory of law as a normative system is the relevance of moral argument for legal validity. No specific interpretation of morality is implied here. Moral validity is understood as normativity in the sense that the validity of a norm implies a requirement that it be applied and followed. Hence, the issue is how this requirement can be justified regarding law in the model of autonomous reasoning. In this app…Read more

9ResumeIn Autonomy and Law, Springer Nature Switzerland. pp. 205-208. 2025.The account of autonomy and law defended here is founded on the notion of autonomy as the balancing of normative arguments. It is distinct from common accounts of normative reasoning and of law in various respects. Its core elements are normative arguments, the normative competence of autonomous agents to present such arguments, normative judgements as the result of balancing, criteria of rational balancing and the demand of intersubjective reflection, and objective validity grounded on reasonab…Read more

24The Logical Structure of PrinciplesIn Autonomy and Law, Springer Nature Switzerland. pp. 27-45. 2025.The distinction between normative arguments and normative judgements or statements has been developed as a reconstruction of Dworkin’s thesis that rules and principles are logically distinct types of norms. His approach that principles are reasons to be balanced against competing principles, whilst rules are applied in an all-or-nothing fashion, links a normtheoretical feature to a specific method of application. However, whether such a distinction is tenable is a matter of dispute. The most pro…Read more

20Autonomy and LawSpringer Nature Switzerland. 2025.This book defends the idea of autonomy as the balancing of normative arguments, which captures the essential feature of autonomous judgement as being simultaneously free and normatively bound. However, this approach runs counter to the dominant view of arguments as propositions, and to Kantian notions of autonomy. Here, it is applied to three core dimensions of law: law as legal system, as legal practice, and as normative judgement, leading to specific views of legal validity, legal interpretati…Read more

182Why non-monotonic logic is inadequate to represent balancing argumentsArtificial Intelligence and Law 11 (2): 211-219. 2003.This paper analyses the logical structure of the balancing of conflicting normative arguments, and asks whether non-monotonic logic is adequate to represent this type of legal or practical reasoning. Norm conflicts are often regarded as a field of application for non-monotonic logics. This paper argues, however, that the balancing of normative arguments consists of an act of judgement, not a logical inference, and that models of deductive as well as of defeasible reasoning do not give an adequat…Read more

26Kelsen on Natural Law and Legal ScienceIn John McGarry, Ian Bryan & Peter Langford (eds.), Kelsenian Legal Science and the Nature of Law, Springer Verlag. pp. 257-273. 2017.Kelsen rejects the scientific character of natural-law doctrine. For Kelsen, value judgments are ultimately not rationally justified but a matter of emotions. They can be rationally justified only relative to a certain moral or legal order. Kelsen also rejects the assumption of natural-law doctrines that value is immanent in reality. On the other hand, he suggests that legal science is possible regarding positive law, which is converted into a normative order by presupposing a “basic norm”. I wi…Read more

100Proportionality as a Universal Human Rights PrincipleIn David Duarte & Jorge Silva Sampaio (eds.), Proportionality in Law: An Analytical Perspective, Springer Verlag. pp. 3-24. 2018.Proportionality is the standard that guides the balancing of human or fundamental rights in law, requiring that the interference with rights must be justified by reasons that keep a reasonable relation with the intensity of the interference. One may well regard the principle of proportionality as a universal standard of rationality, which any legal system must recognise. Thus, when applied to human rights, proportionality presents a universal human rights principle. However, the thesis of the un…Read more
