Introduction
The question of whether judges make law is a central debate in legal theory and practice, particularly within the context of the UK’s uncodified constitution. This essay explores the dual perspectives on this issue: the view that judges do indeed create law through judicial decisions, and the contrasting position that their role is limited to interpreting and applying existing law. The discussion is situated within the framework of the UK legal system, drawing on the doctrine of precedent, statutory interpretation, and constitutional principles such as the separation of powers. By examining key arguments, supported by academic sources and case law, this essay aims to critically evaluate both sides of the debate. The structure will first consider the perspective that judges make law, followed by the opposing view, before concluding with a balanced reflection on the implications of this ongoing contention.
Judges as Law-Makers: The Case for Judicial Creativity
One of the primary arguments supporting the notion that judges make law stems from the doctrine of precedent, or stare decisis, which underpins the common law system in the UK. According to this principle, decisions made in higher courts are binding on lower courts, effectively creating legal rules that must be followed in subsequent cases. This process inherently involves law-making, as judicial rulings establish principles that shape future legal outcomes. For instance, landmark cases such as Donoghue v Stevenson (1932) introduced the neighbour principle, which fundamentally expanded the law of negligence (MacCormick, 1978). By establishing a duty of care, the House of Lords arguably created a new legal standard, demonstrating judicial creativity beyond mere interpretation.
Furthermore, statutory interpretation often necessitates a degree of law-making by judges. When legislation is ambiguous or silent on specific issues, judges must fill gaps to reach a decision. The use of purposive interpretation, especially in the context of European Union law prior to Brexit, allowed judges to align statutes with broader policy objectives, sometimes extending the literal meaning of the text. As Hart (1961) notes, the open texture of legal language means that judges inevitably exercise discretion in hard cases, effectively crafting law to address novel situations. A prominent example is the case of R v Registrar General ex parte Smith (1991), where judicial interpretation clarified statutory provisions in ways that arguably created new legal understandings.
Indeed, the evolving nature of society often demands that judges adapt legal principles to contemporary contexts, further supporting the view that they make law. Issues such as technological advancements or shifting social norms may not be adequately addressed by existing statutes or precedents. For instance, judicial decisions in family law have progressively recognised changing definitions of relationships, thereby shaping legal norms in ways that Parliament may not have anticipated (Herring, 2019). This adaptability, while beneficial, raises questions about the extent to which unelected judges should influence policy, a point to be revisited later.
Judges as Interpreters: The Case Against Law-Making
On the other hand, the traditional view, rooted in the separation of powers, asserts that judges do not make law but merely interpret and apply it. This perspective aligns with the constitutional principle that law-making is the exclusive domain of Parliament, the elected legislative body. As Blackstone famously argued, judges are “not delegated to pronounce a new law, but to maintain and expound the old one” (Blackstone, 1765). In this light, judicial decisions are seen as declarations of pre-existing legal principles rather than creations of new law. The role of precedent, therefore, is not to invent rules but to ensure consistency in applying established norms.
Moreover, statutory interpretation, while sometimes creative, is constrained by the intention of Parliament. Judges often employ tools such as the literal rule or the golden rule to adhere closely to legislative text, avoiding overstepping into legislative territory. For example, in Duport Steels Ltd v Sirs (1980), Lord Diplock emphasised that judicial function is to give effect to parliamentary intent, not to substitute it with personal or policy-driven views. This suggests a clear boundary to judicial influence, countering the notion of law-making (Dworkin, 1977). Even in cases where discretion appears evident, it can be argued that judges are resolving ambiguities within the framework of existing law rather than crafting entirely new rules.
Additionally, the hierarchical structure of the UK judiciary and the ability of higher courts to overrule previous decisions demonstrate that judicial law-making, if it exists, is not absolute. The Supreme Court, for instance, can depart from its own precedents under the 1966 Practice Statement, but this power is exercised sparingly, reflecting a reluctance to destabilise legal certainty. Critics of the law-making view argue that such mechanisms ensure judges remain interpreters, correcting errors rather than legislating (Atiyah & Summers, 1987). Generally, this reinforces the democratic principle that law should originate from elected representatives, not the judiciary.
Critical Evaluation and Middle Ground
Balancing these perspectives reveals a complex reality. While judges undoubtedly influence the development of law through precedent and interpretation, their role is arguably distinct from the deliberate, prospective law-making of Parliament. The question hinges on semantics: does ‘making law’ imply creating entirely new legal frameworks, or does it encompass incremental changes within existing structures? Hart’s (1961) concept of judicial discretion suggests that law-making is inevitable in hard cases, yet Dworkin (1977) counters that even discretionary decisions are guided by underlying legal principles, not personal whim. This debate highlights a tension between legal certainty and the need for adaptability.
Moreover, the practical implications of judicial law-making cannot be ignored. If judges are seen as law-makers, this risks undermining democratic accountability, as they are unelected and unanswerable to the public. Conversely, rigid adherence to the interpretive role might hinder justice in rapidly changing societal contexts. A middle ground might be that judges participate in a form of limited law-making within constitutional boundaries, complementing rather than usurping parliamentary authority (Herring, 2019).
Conclusion
In conclusion, the question of whether judges make law in the UK legal system remains contentious, with valid arguments on both sides. Those in favour highlight the creative role of precedent and statutory interpretation, evidenced by cases like Donoghue v Stevenson, where judicial decisions have expanded legal principles. Conversely, proponents of the interpretive view stress the constitutional separation of powers and the judiciary’s duty to uphold parliamentary intent, supported by judicial restraint in cases such as Duport Steels Ltd v Sirs. This essay suggests that while judges inevitably influence law through their rulings, their role is better understood as a constrained form of development rather than outright creation. The implications of this debate are significant, touching on issues of democratic legitimacy and legal adaptability. Further exploration of how judicial and legislative functions can be balanced remains essential for ensuring both justice and accountability in the UK legal system.
