Jurisprudence and legal theory – Core notes (University of London LA3005)

Part I The nature of law and jurisprudence

1 Introduction

Purpose of the module guide: develop foundation in law and political philosophy; foster reflective, critical thinking about law and its legitimacy; link theory to doctrinal questions.
Focus: Anglo-American, common-law tradition; develop legal reasoning and argument construction; readiness for examination.

1.1 How to study jurisprudence

Start with open-minded engagement; read primary sources (e.g., Hart, Dworkin, Fuller, Finnis) and key secondary readings; track central ideas rather than memorising details.
Build a coherent study pattern: sustained reading, note-taking, and practice paragraphs/essays; discuss with others to refine arguments.
Fuller’s Case of the Speluncean Explorers is a recommended introductory reading to see how simple facts can yield diverse theoretical responses.

1.2 What is jurisprudence?

Jurisprudence studies the nature of law, its morality, legitimacy, and social function; involves big philosophical questions: What is a definition? What is a rule? What is law? What is morality? What is justice?
It also covers questions about political morality, equality, punishment, and rights; intersects with sociology and history of law.
Figures to know: Austin, Bentham (power/command), Hart (authority and normativity), Fuller (inner morality of law), Dworkin (law as integrity), Finnis (modern natural law), Raz (authority/practical reason).

1.3 Reading

Core text: Freeman, Lloyd’s Introduction to Jurisprudence. Read extracts in Freeman alongside module readings.
Supplementary texts: Hart’s The Concept of Law; Dworkin’s works; Simmonds; Penner & Melissaris; Finnis; Fuller; etc.
Approach: read primary sources with guide materials; distinguish central cases and normative arguments; note the difference between description and evaluation.

1.4 Preparing for an examination in jurisprudence

Exam setup: a set case, one question from Part One, and three questions from Part Two. Analysts must connect cases to jurisprudential theories.
Structure of an answer (typical): opening/position, central argument with reasons and literature, structured support, and a concise summing-up; use the case to illustrate theory.
Distinguish between theory of law and moral/political evaluation; include own stance with reasons.
Practice with past papers; develop structure for trial paragraphs and essays; highlight how different theories illuminate a case.

Part II Natural law

2 Classical and modern natural law theory

Natural law: law as an application of morality; law’s legitimacy grounded in human nature, rationality, or God’s will depending on the theorist.
The positivist critique argues that law is a social technology that may be wicked yet remains law; morality is not entailed by law, though some theorists defend close ties.
Key debates: how law and morality relate; whether there exists a universal basis for law; whether law must reflect moral values.

2.1 The rise of natural law in ancient Greece and Rome

Early natural law linked law to morality and universal human nature; different thinkers offered universal standards of right and wrong beyond local customs.
The jus gentium (law of nations) represented a higher‑order natural law applicable across cultures.
The natural law tradition confronted positivism in modern periods: some natural lawyers argued for a strong tie between morality and law; positivists argued law can be independent of morality.

2.2 The natural law of Aquinas: structure

Aquinas integrates Aristotle with Christian theology: four orders of law
- Eternal law: divine providence ordering the universe.
- Natural law: participation of human reason in divine order.
- Human law: particular rules derived from natural law, applied by human institutions.
- Divine law: revelation guiding humans toward salvation.
Key distinctions: specificatio (what the natural law lays down in detail) vs determinatio (what human law must decide within natural-law bounds).

2.3 The natural law of Aquinas: legal reason, human law and the obligation to obey the law

Law obliges in conscience only to the extent it aligns with natural law; unjust laws are still laws in form, but obeying them is morally dubious.
Humans are bounded reasoning agents; equity may justify departures from strict rules in exceptional cases.
Custom matters; changing laws too often undermines legitimacy.

2.4 Laws that uplift human personality

Natural law embodies a vision in which law uplifts fundamental human goods and personality (e.g., civil rights, equality). MLK serves as an illustration of 20th-century natural law thinking in action.
Discussion point: laws that uplift personality versus those that degrade it; balancing moral ideals with practical governance.

2.5 Social contract and states of nature

Enlightenment thinkers (Hobbes, Locke, Rousseau) theorised that society forms through a social contract to escape the state of nature.
Hobbes emphasizes a strong sovereign to prevent a war of all against all; Locke emphasizes protection of natural rights; Rousseau emphasizes collective freedom.
The social-contract framework links to modern theories of legitimacy and the authority of the state; connects later with Rawls and liberal theory.

2.6 Modern natural law theory I: Finnis

Finnis defends a modern natural-law framework that integrates positivism insights but rejects the claim that law is only a social convention.
Core idea: there are basic goods (life, knowledge, play, aesthetics, friendship, religion, practical reasonableness) grasped directly, not derived from facts; seven basic values are irreducible and non‑commensurable.
The law's subject matter is determined by these basic goods; the “focal meaning” determines the scope of legal theory; law is a practical enterprise aimed at enabling flourishing.
Response to the fact–value distinction: Finnis denies deriving ought from is; morality grounds legal normativity through practical reasonableness.

2.7 Modern natural law theory II: Fuller

Fuller rejects a grand moral theory; instead, he articulates the inner morality of law through the rule of law: governance by clear, general rules; procedural justice in law-making and administration.
Eight (plus one) principles of legality: promulgation, non-retroactivity, generality, clarity, non-contradiction, feasibility (not requiring the impossible), consistency with official action, and stability; plus an overarching sense that law must serve justice.
Hart criticizes Fuller for conflating purposive activity with morality; Fuller responds by stressing the normativity of law’s procedural form.

2.8 The continuing debate over the connection between law and morality

Ongoing debate: whether law must be inherently moral or can be neutral; Finnis and Fuller defend versions of natural-law analysis against positivist objections; Dworkin and others offer interpretive challenges to positivism.
Readings suggest continued exploration of how normativity and legitimacy arise in law and how moral theory informs legal practice.

Part III Legal positivism

3 Imperative or command theories of law

Core idea: law as commands issued by a sovereign or power-bearing actor; distinction between law and morality; laws are statements of what must be done, backed by sanctions.
The tradition begins with Hobbes (state as sovereign), Bentham (utilitarian critique and reform), and Austin (the province of jurisprudence; law as commands of the sovereign).

3.1 The birth and development of secular or ‘positive’ theories of law: the case of Thomas Hobbes

Hobbes presents a materialist, secular view; law emerges from the social contract to escape the state of nature; a strong sovereign is necessary to ensure social survival.
Hobbes helps lay groundwork for the idea that law can be an artifact of political power, separate from divine authority.

3.2 Jeremy Bentham

Bentham: law should serve the greatest happiness of the greatest number; utilitarian calculation guides legal reform; critical of natural rights as nonsense on stilts.
Emphasised rational reform through law; viewed law as a means to social improvement; associated with utilitarian calculus and reformist politics.

3.3 John Austin

Austin argues that law is a command of a sovereign backed by a sanction; law is distinguished from morality; the sovereign’s commands create legal validity.
Distinctions: sovereign vs. subject, positive law vs. moral law; excluding morality as a descriptive component of law.

3.4 Appreciating Austin’s command theory

Strengths: clarity and certainty about the structure of law; helps separate law from morality in analysis.
Weaknesses: overly simplistic; excludes international and customary law; difficulty identifying a single sovereign in complex modern states; fails to account for law’s powers and rules that confer authority.

4 Introduction to Hart’s The Concept of Law

Hart reframes positivism by introducing a more sophisticated analysis: law as a system of rules, not merely commands backed by threats.

4.1 Studying Hart; 4.2 Hart’s aims; 4.3 Definition and theory; 4.4 OB T theory criticisms; 4.5 The union of primary and secondary rules; 4.6 Other chapters; 4.7 Internal vs external POV; 4.8 Following rules

Hart rejects the simplicity of OBT (Orders Backed by Threats) and proposes a two-tier structure: primary rules (obligations) and secondary rules (rules about change, adjudication, and recognition).
The internal point of view captures how officials accept rules; the external view describes how others describe the system.

5 A master rule for law: Hart’s rule of recognition

Rule of recognition identifies which norms count as law in a given system; empirical fact about official practice, not a moral justification.
Distinguishes between supreme criterion (e.g., parliamentary enactment in the UK) and ultimate rule (the rule of recognition itself).
The Postscript clarifies Hart’s descriptive aim vs. normative interpretations; Dworkin challenges Hart’s account with interpretive perspectives.
Finnis critiques Hart for insufficiently connecting normativity with norm-identification; Dworkin critiques Hart for insufficiently handling hard cases and moral reasoning.

6 The Hart–Fuller debate

Nazi grudge informer case used to contrast positivist clarity with Fuller’s commitment to morality and procedural justice.
Fuller proposes eight principles of the inner morality of law; Hart defends a separation of law and morality while acknowledging moral considerations in law’s practice.

7 Kelsen

Kelsen introduces the pure theory of law: law as a normative system, where validity is grounded in a Grundnorm (basic norm) rather than empirical social practice.
Delineates between primary norms (duty-imposing) and secondary norms; delicts vs. duties; the Grundnorm is a presupposition, not an observable fact.
Revolutions and the unity of legal systems: legal validity depends on effectiveness, but Grundnorm is a transcendental postulate not reducible to social fact.

7.1–7.5 Key comparisons: Austin, Hart, Kelsen

Kelsen’s Grundnorm aims to separate norm from fact; Hart roots validity in social practice via rule of recognition; Austin relies on sovereign power.

8 Raz

Raz emphasizes authority and normative reasons; the paradox of authority (why follow authority) is resolved by Raz’s service-conception of authority: authorities mediate between us and the balance of reasons.
The normal justification thesis: an authority is legitimate if following it yields better guidance than acting on one’s own balance of reasons.
Exclusionary reasons: deliberative vs. executive phases of practical reason; authorities provide exclusionary reasons to implement decisions.
The scope and force of exclusionary reasons; limits of law when morality is controversial; thus soft positivism and Dworkin’s interpretivism face scrutiny under Raz’s framework.

Part IV The integrity and interpretation of law

9 Dworkin’s interpretive theory

Dworkin argues that law is an interpretive enterprise, not a fixed catalogue of rules; Judge Hercules represents the ideal judge who interprets the law in light of rights and moral principles.
Distinguishes between principles (rights-based, normative) and policies (consequentialist or societal goals).
The fit-substance distinction: decisions should fit existing law (precedent and statutes) unless there is a stronger substantive moral claim.
Dworkin contends that there can be right answers in hard cases; law’s integrity provides a unified narrative that respects individuals’ rights and the law’s practice.

10 Liberalism and law

Liberalism emphasizes liberty and equality; utilitarianism critiques and Rawls’s theory of justice are central.
Tensions between liberty and equality; Devlin–Hart discussions on enforcing morality; the harm principle; toleration and the limits of state intervention.
Nozickian libertarianism vs. Rawlsian egalitarianism; debate about distribution, rights, and social structure.

11 Marx, Marxism and Marxist legal theory

Marx links law to the economy; ideology and the state reflect class interests; law as an instrument of bourgeois power in capitalist society.
Soviet Marxism and the law: the legal system as part of the state’s apparatus; Pashukanis’s critique of bourgeois law as linked to capitalist exchange; Western Marxism (Althusser) reframes law in terms of the superstructure and ideological state apparatuses.
Western Marxism emphasizes that law cannot be reduced to simple economic determinism; law participates in the complex totality of social relations.

12 Feminist legal theories

FLT seeks to reveal how law constructs gendered worlds and sustains women’s disadvantage; multiple approaches: liberal (equality before law), care ethics (relationships and context), radical feminism (power and domination), Black feminism (intersectionality), postmodern/critical perspectives.
History: first wave (rights-based equality; suffrage); second wave (reproductive rights, work, violence against women); postmodern critiques question universal claims and emphasize context, difference, and power relations.
Core concerns include equality vs. difference; universal scope of law; impact of gender, race, class on legal practices; consciousness-raising, and the politics of reform.

Part V Liberalism, justice and critical perspectives on law

10 Liberalism and law

Theories of justice: utilitarianism (Bentham, Mill), virtue ethics, deontological (Rawls, Kantian) perspectives; trade-offs between liberty and equality; Harm Principle and the balancing of competing values.
Rawls’s original position: behind a veil of ignorance, two principles of justice: (1) equal basic liberties, (2) social/economic inequalities arranged to benefit the least advantaged (differences principle) with fair equality of opportunity.
Critiques (Nussbaum, Sen) focus on capabilities and real-life functioning beyond mere resources; debates about equality of opportunity vs. outcome; communitarian critiques (Sandel).

11 Marxist theory

Class as central; law serves the interests of the ruling class; the state as instrument of capitalist social relations; analysis of imperialism and global capital; Althusser’s ideology and ISAs (ideological state apparatuses).
Western Marxism critiques Soviet-style socialism and seeks a more nuanced understanding of law within global capitalism; questions about real mechanisms for justice under capitalism.

12 Feminist legal theories

FLT continues to develop critical approaches to law from gender perspectives; emphases include intersectionality, critique of universal claims, and attention to lived experiences of women.
Postmodern feminism critiques universalist claims and emphasizes diverse experiences; the hope for reform through feminist jurisprudence and human rights frameworks.

Exam-ready Core Concepts (glossary)
