Comprehensive Study Guide for Jurisprudence and Theories of Law and Justice
Convener Background and Institutional Context
Academic Background: The unit convener is an Italian scholar who studied law at the University of Genoa. Their postgraduate education was completed at Oxford, where they earned a Master's and a Doctorate (DPhil) in law. Teaching experience at Oxford included colleges such as University College, Merton, or similar (though specific college names were associated with transitions), focusing on jurisprudence, constitutional law, and constitutional theory. In , they joined Macquarie Law School.
Research Profile: Approximately of the convener's workload is dedicated to research. Their expertise lies in three primary areas:
Sovereignty: The nature and limits of political and legal authority.
Legal Reasoning: Dealing with disagreements regarding the content of law and how officials identify implicit exceptions to established rules.
Methodology: The formation of concepts to capture and explain social reality, exemplified by the social construction of concepts like money (e.g., Roman coins).
Institutional History: Macquarie Law School, established in , is characterized by its "law in context" approach to legal education. The Michael Kirby building is the current facility used for instruction.
Administrative Framework for Jurisprudence and Theories of Law and Justice
Unit Structure: The course is shared between two units: Jurisprudence (for undergraduate students) and Theories of Law and Justice (for JD students). These lectures are also utilized for Session (summer term) offerings.
Enrollment Statistics: As of the start of the session, there are approximately students enrolled in Jurisprudence and roughly students in Theories of Law and Justice.
Assessments and Communication: Information pertaining to assessments (research essay and final exam) is found in the unit guide and on the iLearn page. The unit guide serves as the authoritative document in the event of inconsistencies. Administrative and content-related questions should be directed to the general discussion forum on iLearn to ensure all students benefit from the responses. Private matters should be handled via the iLearn message function rather than email.
Tutorial Attendance: Students can miss up to three tutorials without applying for special consideration, provided they follow instructions on iLearn to record and share a video demonstrating engagement with the tutorial material.
The Nature and Scope of Jurisprudence
Etymology: The term "jurisprudence" arrives from Latin, combining juris (the root of ius, meaning law or right) and prudentia (meaning wisdom, foresight, or knowledge). It essentially represents wisdom about the law.
Diverse Applications: Beyond legal theory, the term is used in contexts such as "the jurisprudence of a court" (referring to a body of judicial decisions), "religious law," and "medical jurisprudence."
Equivalence in Terminology: For the purposes of this study, jurisprudence is often used interchangeably with "legal theory" and "legal philosophy." However, scholars like Roger Cotterell argue in "Why Jurisprudence is Not Legal Philosophy" that these terms should be distinguished.
Distinction Between General and Particular Jurisprudence
General Jurisprudence: This is a philosophical inquiry into the nature of law in general. It is not limited to a specific jurisdiction but seeks to understand the law as a universal social phenomenon. It addresses questions such as "What is law?", "What is a legal system?", and "Is there a general obligation to obey the law?"
Particular Jurisprudence: This focuses on puzzles or features present in specific legal systems or traditions. Examples include inquiries into what is distinctive about the Common Law or the nature of parliamentary sovereignty in systems like the United Kingdom or Australia.
Analytical Jurisprudence and the Legacy of H.L.A. Hart
Historical Context: Analytical jurisprudence involves the conceptual analysis of ideas relevant to the legal domain. It has a long tradition involving figures like Jeremy Bentham and John Austin.
H.L.A. Hart's Contribution: Modern analytical jurisprudence is often dated to the publication of The Concept of Law in by H.L.A. Hart. Hart was the Chair of Jurisprudence at Oxford from to . His inaugural lecture, "Definition and Theory in Jurisprudence," set a new research project for the field.
Philosophical Methodology: Hart combined traditional analytical jurisprudence with the analytical philosophy prevalent at Oxford in the mid- century, which emphasized the analysis of language and specifically "ordinary language philosophy."
The Postscript: The second edition of The Concept of Law () includes a postscript where Hart responds to various critics, most notably Ronald Dworkin. This postscript, edited by figures including Joseph Raz, clarifies Hart's view of his own work as a descriptive, general theory of law.
Methodology: Conceptual Analysis and Descriptive Sociology
Conceptual Analysis: This refers to the philosophical effort to clarify concepts by setting boundaries. It helps establish common ground for investigation. Disagreements in this area can be semantic (about the meaning of a term) or conceptual (where parties do not share the same underlying idea).
Hart's Dual Claim: Hart famously described The Concept of Law as both an essay in analytical jurisprudence and an essay in "descriptive sociology." This claim is controversial, as many see analysis and sociology as distinct disciplines. William Twining and others have debated whether Hart's work successfully bridged these fields.
Distinction Between Theoretical and Metatheoretical:
Theoretical claims are about the object (e.g., "Law is a system of rules").
Metatheoretical claims are about the theory itself (e.g., "A theory of law should be morally neutral").
Methodological questions address how we should investigate the object (e.g., "Can we investigate the nature of law like a natural scientist?").
Practical Application: Theory and Judicial Reasoning
Legal theories often inform actual legal practice and judicial decision-making. Examples include:
Mabo: The reasoning involved assumptions about the nature of law derived in part from the tradition of John Austin.
Miller (Brexit Case): This case involved judges grappling with the "rule of recognition," a concept central to H.L.A. Hart's theory, to determine the constitutional architecture of the UK.
Analytical Framework: Types of Legal Questions
To understand legal theory, one must distinguish between various types of inquiries:
Conceptual: "What is law?" or "What is a contract?" (in a general sense).
Doctrinal: "What is the law here on this particular issue?" (e.g., the content of New South Wales contract law).
Normative: "Should we change the law?" or "Is this law good?" (dealing with how things "ought" to be).
Empirical/Explanatory: "How does this law affect the community in practice?" (dealing with the actual social effects of legal rules).
H.L.A. Hart's Three Persistent Questions
Hart argues that the search for a definition of law is driven by three recurring perplexities:
How does law differ from and relative to orders backed by threats? (The relationship between law and coercion).
How does legal obligation differ from and relative to moral obligation? (The relationship between law and morality).
What are rules, and to what extent is law an affair of rules? (The nature of social rules versus legal rules).
The Problem of Definition in Jurisprudence
Knowing vs. Understanding: Hart distinguishes between being able to recognize and use the law (knowing) and being able to explain its general nature (understanding). He illustrates this with the quote: "In law as elsewhere, we can know and yet not understand."
The Failure of Traditional Definition: Traditional definitions often use the method of per genus et differentiam (definition by genus and difference).
Example: A triangle is defined by its genus (rectilinear figure) and its difference (being three-sided).
Hart's View: Hart argues that this method is not helpful or possible for defining "Law" because there is no widely agreed-upon general category (genus) that covers all and only legal phenomena without circularity.
The Purpose of Definition as a Map: For Hart, a definition of law should serve as a map, showing the relationship between the law we know and other social phenomena like morality, coercion, and social etiquette.
Major Traditions in Modern Jurisprudence
Legal Positivism: Represented by H.L.A. Hart, John Austin, and Joseph Raz. It generally asserts that the law is a social fact and is conceptually distinct from morality (the "Separation Thesis").
Natural Law Tradition: Represented by Lon Fuller and John Finnis. This tradition argues that law is inherently connected to moral reasons and the "common good."
Interpretivism: Represented by Ronald Dworkin, who argued that law is not just a system of rules but also includes moral principles that provide the best justification for legal practice.
Legal Realism: A perspective focusing on how law actually functions in courts and the role of judicial discretion.
Contemporary Scholarly Perspectives
John Gardner: Viewed jurisprudence as a branch of philosophy. He argued that philosophical education allows one to find "timeless problems" underlying "topical problems" in the law.
Leslie Green: Suggested that legal philosophy provides an "escape from the default setting" of one's own legal system by allowing for deep critical and normative reflection.
Julie Dickson: Author of Elucidating Law () and an authority on legal methodology. She explores how a proper understanding of law affects our "practical reasoning"—the reasoning we use to decide how to act and whether the law has authority over us.
