Rights and Raz
Raz's service conception, exclusionary reasons, legal positivism, and the interest theory of rights
§01 Overview
Joseph Raz's contribution to jurisprudence represents one of the most sustained and systematic defences of legal positivism in the late twentieth and early twenty-first centuries. This note explores three interlocking dimensions of Razian theory: first, his refinement of Hart's positivism into what he terms 'exclusive' legal positivism, premised on the sources thesis; second, his service conception of authority and the related theory of exclusionary reasons; and third, his interest theory of rights, which stands in sharp contrast to the will theory advanced by Hart.
Raz parts company with Hart on several fronts—most notably in denying that law necessarily claims moral correctness (contra Alexy and Finnis) while insisting that it does necessarily claim legitimate authority. For Raz, law is not simply a union of primary and secondary rules; it is an institutionalised normative system purporting to mediate between subjects and the reasons that already apply to them. Legal norms are posited, not derived from morality, yet their existence and content depend on social facts alone (the sources thesis). This raises the central puzzle: how can law claim authority if its directives may conflict with what subjects ought, morally, to do?
Raz's answer—the normal justification thesis—asserts that authority is legitimate only when subjects are more likely to comply with right reason by following the authority's directives than by acting on their own judgment. Legal rules function as exclusionary reasons: they do not merely add weight to the balance of first-order reasons; they exclude some reasons from practical deliberation altogether. This conception has profound implications for legal reasoning, the nature of legal obligation, and the limits of judicial discretion.
The interest theory of rights completes the picture. Against Hart's will theory—which locates the essence of a right in the rightholder's control—Raz argues that X has a right if an aspect of X's well-being is sufficient to hold another under a duty. This shifts focus from autonomy to welfare and better accounts for the rights of children, animals, and incapacitated persons.
This note situates Raz within the post-Hartian landscape, critically examines his major theses, and equips you to deploy Razian arguments in tutorial essays and examination answers on authority, rights, judicial reasoning, and the boundaries of legal positivism.
§02 Historical Context and the Post-Hartian Debate
Joseph Raz studied under H.L.A. Hart at Oxford in the 1960s and succeeded him as Professor of the Philosophy of Law in 1985. His major works—The Concept of a Legal System (1970, revised 1980), Practical Reason and Norms (1975, revised 1990), The Authority of Law (1979), The Morality of Freedom (1986), and Ethics in the Public Domain (1994)—consolidate and extend the positivist project inaugurated by Bentham, Austin, Kelsen, and Hart.
From inclusive to exclusive positivism
Hart's postscript to The Concept of Law (published 1994) acknowledged a major fault line within positivism. Inclusive (or soft) positivism—defended by Jules Coleman, Wilfrid Waluchow, and (on some readings) Hart himself—permits a rule of recognition to incorporate moral criteria for legal validity. A legal system may make moral merit a condition of legality, though it need not do so. Exclusive (or hard) positivism, championed by Raz, denies this possibility: if morality determines legal validity, the sources thesis is violated and law loses its distinctive claim to authority.
Raz's position crystallised in response to Dworkin's attack on positivism. Where Dworkin argued that legal systems necessarily include principles identifiable only by moral reasoning, Raz replied that law's content is exhausted by source-based norms. Principles may guide judges, but only those traceable to conventional pedigree (legislation, precedent, custom) count as law.
The turn to practical reason
Raz's originality lies in grounding legal theory in a broader account of practical rationality. Unlike Hart, who saw law as a social practice to be described from the internal point of view, Raz insists that legal philosophy must engage normative questions: under what conditions does law generate genuine obligations? When is obedience rational? These are not sociological queries but questions in practical reason.
This move prefigures contemporary debates between positivism and natural law (Finnis) and between positivism and interpretivism (Dworkin). Raz occupies an unusual position: a positivist who takes normativity seriously, rejecting both Kelsenian reductionism and Dworkinian interpretivism.
Influence and legacy
Raz's service conception has been adopted, adapted, and criticised by philosophers and constitutional theorists (e.g., Larry Alexander, Frederick Schauer, Scott Shapiro). His interest theory animates contemporary rights scholarship, particularly in human rights and constitutional adjudication. Yet Raz remains a polarising figure: admirers praise his analytical rigour; critics charge him with conceptual over-refinement and neglect of law's social functions.
§03 Key Principles: The Razian Framework
Raz's jurisprudence rests on five interlocking theses. Mastery of these is essential for tutorial discussion and examination success.
1. The sources thesis
The sources thesis asserts: A jurisprudential theory is acceptable only if its tests for identifying the content of the law and determining its existence depend exclusively on facts of human behaviour capable of being described in value-neutral terms, and applied without resort to moral argument (Raz, The Authority of Law, Essay 3).
This thesis excludes moral reasoning from the identification of law. Legal validity turns on pedigree—enactment, promulgation, precedent—not on conformity to justice. The rule of recognition, on Raz's account, cannot incorporate moral standards without ceasing to be a social rule grounded in official consensus.
The sources thesis entails the social thesis: all law is source-based, i.e., created by human acts in social contexts. It also supports the no-necessary-connection thesis: there is no conceptual link between law and morality, though contingent connections abound.
2. The service conception of authority
Law claims authority. But what makes such claims legitimate? Raz's answer: authority serves its subjects by helping them comply with reasons that already apply to them (the normal justification thesis, or NJT).
Formally: The normal way to establish that a person has authority over another person involves showing that the alleged subject is likely better to comply with reasons which apply to him (other than the alleged authoritative directives) if he accepts the directives of the alleged authority as authoritatively binding and tries to follow them, rather than by trying to follow the reasons which apply to him directly (The Morality of Freedom, p. 53).
Authority mediates between subjects and right reason. The law does not create new reasons ex nihilo; it provides a more reliable route to conformity with pre-existing (often moral) reasons. This is the service authority renders.
§04 Statutory Framework and Institutional Analogues
Raz's theory is pitched at a high level of abstraction, addressing the general concept of authority rather than parsing particular enactments. Nonetheless, his framework illuminates the structure and function of specific legal instruments.
The Human Rights Act 1998
Section 3(1) HRA 1998 requires courts to read legislation compatibly with Convention rights 'so far as it is possible to do so'. Section 4 permits (but does not require) a declaration of incompatibility when compatibility is impossible.

§05 Landmark Cases and Judicial Reasoning
While Raz's theory operates at a philosophical rather than doctrinal level, judicial decisions illustrate—and sometimes challenge—his claims about authority, reasons, and rights.
R v Howe [1987] AC 417 (House of Lords)
The House of Lords held that duress is no defence to murder. Lord Hailsham acknowledged the 'moral discomfort' of convicting a defendant who killed under threat of death, but insisted that policy and legal principle required a bright-line rule.
Razian analysis: the ruling exemplifies exclusionary reasoning. Judges set aside individualised moral assessments (whether this defendant acted reasonably under duress) in favour of a categorical rule. The rule pre-empts first-order moral reasons, serving the law's systemic interests in certainty and the protection of innocent life. Authority's exclusionary force is evident.

§06 Doctrinal Development and Refinements
Raz's core theses have evolved through sustained dialogue with critics and changing intellectual contexts. This section traces major developments and internal tensions.
From The Concept of a Legal System to The Authority of Law
Raz's doctoral thesis, The Concept of a Legal System (1970), refined Kelsen's hierarchy of norms and Hart's rule of recognition. Raz argued that legal systems are individuated by their ultimate sources of law (typically a constitution or Grundnorm) and must claim supremacy and completeness.
Supremacy: the legal system claims authority to regulate any type of behaviour. Completeness: the system claims to provide for all situations requiring adjudication, either through explicit rules or gap-filling mechanisms.
By The Authority of Law (1979), Raz shifted focus from systemic structure to authority's normative foundations. The sources thesis remained central, but Raz now grounded it in practical reason: only source-based rules can function as exclusionary reasons, because moral reasoning (by its nature) is not exclusionary—it invites contestation and deliberation.

§07 Academic Debates: Critics and Defenders
Raz's theories have generated extensive scholarly controversy. This section maps key debates, essential for critical engagement in tutorials and essays.
Dworkin's challenge: law as interpretation
In Law's Empire (1986), Dworkin argued that legal reasoning is inherently interpretive: judges identify law by constructing the best moral justification of institutional history. Raz's sources thesis is, on this view, fatally incomplete—it cannot account for how judges actually decide hard cases.
Raz's response appears in 'Authority, Law and Morality' (1985) and subsequent essays. He insists that Dworkin conflates what the law is (a question of social fact, answered by the sources thesis) with what judges should do (a question of political morality, often requiring reasoning beyond law). In hard cases, judges may exercise discretion, guided by moral and policy considerations, but this does not make those considerations 'law'. Law runs out; judicial obligation continues.
Dworkin retorts that this concedes too much: if judges in hard cases must reason morally to discharge their institutional duty, and if this reasoning is subject to professional constraint (they cannot decide arbitrarily), then the criteria of legal validity extend beyond sources. Raz's sharp separation of law and adjudication is, for Dworkin, untenable.

§08 Comparative Perspective: Authority and Rights in Other Traditions
Raz's theories invite comparative scrutiny. How do other legal cultures conceptualise authority and rights? Does the service conception travel?
Continental legal positivism: Kelsen and beyond
Hans Kelsen's Pure Theory of Law (1934, 2nd ed. 1960) influenced Raz's early work, but the two diverge sharply. Kelsen's Grundnorm is a transcendental presupposition, epistemologically necessary to cognise law as a normative system. Raz rejects this Kantian apparatus: the rule of recognition is an empirical social fact, not a presupposition. Moreover, Kelsen reduces legal obligation to the internal logic of norms (Sollen), avoiding questions of practical reason. Raz insists that legal philosophy must ask: when does law create genuine obligations?
Post-Kelsenian scholars (e.g., Eugenio Bulygin, Carlos Alchourrón) have developed formal systems for legal reasoning compatible with Raz's sources thesis but agnostic about authority. For Raz, this agnosticism is a vice: it leaves law's normativity unexplained.

§09 Worked Tutorial Essay
Question: 'Raz's service conception of authority is incompatible with his exclusive legal positivism.' Discuss.

Introduction
Joseph Raz defends two central theses that, on first inspection, appear in tension: (1) the service conception of authority, which holds that law's authority is justified when it helps subjects comply with right reason, typically moral reason; and (2) exclusive legal positivism, which insists that law's content is determined solely by social sources, without recourse to moral argument (the sources thesis). The apparent difficulty is this: if law's authority depends on moral justification (the normal justification thesis, NJT), and if law claims authority necessarily, then hasn't Raz smuggled morality into the concept of law, thereby contradicting the sources thesis?
This essay argues that the tension is superficial. Raz carefully distinguishes between (a) law's claim to authority (a conceptual, descriptive thesis) and (b) the justification of that claim (a normative, evaluative thesis). The sources thesis governs (a); the NJT governs (b). Exclusive positivism identifies what counts as law; the service conception evaluates whether law succeeds in its self-proclaimed mission. The two projects are complementary, not contradictory. I defend this reconciliation against three objections: (i) that the NJT presupposes moral reasoning in legal identification; (ii) that authority's exclusionary function is incompatible with source-based law; and (iii) that Raz's account collapses into inclusive positivism.

§10 Common Exam Traps and How to Avoid Them
Razian theory is conceptually demanding, and examinations frequently expose common misunderstandings. This section identifies pitfalls and strategies for success.
Trap 1: Conflating claims and justifications
Mistake: Writing that Raz is inconsistent because he says law claims authority (a moral notion) yet defends the separation thesis.
Correction: Law claims authority (a sociological fact about law's self-presentation); whether the claim is justified is a separate normative question. The separation thesis concerns law's concept (no necessary moral merit), not law's claims (which may be false).
Strategy: Always distinguish (a) law's claim to authority (conceptual), (b) the conditions under which the claim is justified (normative), and (c) whether particular systems meet those conditions (evaluative). Quote Raz: 'The law's claim to authority is one thing; its success in establishing authority is another.'
Trap 2: Misunderstanding exclusionary reasons
Mistake: Treating exclusionary reasons as 'weightier' first-order reasons. E.g., 'The law against murder is an exclusionary reason because it outweighs my reason to kill.'

§11 Practice Questions
Foundation
- Explain Raz's sources thesis. How does it differ from Hart's rule of recognition?
- What is an exclusionary reason? Illustrate with an example from law.
Standard
- 'Raz's normal justification thesis is circular: to know whether to obey authority, I must engage in the moral reasoning authority is supposed to pre-empt.' Discuss.
- Compare and contrast the will theory and interest theory of rights. Which is more convincing?
Challenge
- 'Exclusive legal positivism cannot account for constitutional rights adjudication under the Human Rights Act 1998.' Evaluate this claim with reference to Raz's theory of authority and rights.
