Introduction
The question of whether UK judges create laws is central to understanding the balance of power within the British constitutional framework. The UK operates under an unwritten constitution, where the doctrine of parliamentary sovereignty traditionally positions Parliament as the supreme law-making authority. However, the role of the judiciary in interpreting and applying the law often raises debates about whether judges, through their decisions, effectively create law rather than merely apply it. This essay aims to critically evaluate the extent to which UK judges can be said to create laws, focusing on the mechanisms of judicial precedent, statutory interpretation, and the influence of European and human rights law. By examining key case law and academic perspectives, this piece will argue that while judges do not create law in the formal legislative sense, their interpretative and precedent-setting roles often result in significant law-making influence, albeit within constrained boundaries.
The Doctrine of Precedent and Law Creation
One of the primary ways in which UK judges influence the law is through the doctrine of precedent, or stare decisis, which ensures consistency in judicial decisions. Under this principle, higher courts bind lower courts to follow their rulings, thereby shaping the development of common law. For instance, landmark cases such as Donoghue v Stevenson (1932) established the modern law of negligence by introducing the ‘neighbour principle’ (Lord Atkin, 1932). This decision arguably created a new legal duty of care, demonstrating how judicial rulings can have law-making effects by setting binding precedents.
However, it must be noted that the scope of judicial creativity through precedent is limited. Judges are bound by decisions of higher courts, and the Supreme Court, while possessing the ability to overrule its own past decisions since the Practice Statement of 1966, exercises this power cautiously to maintain legal certainty (Lord Gardiner, 1966). Academic commentators such as Dworkin (1986) argue that judges do not create law in a legislative sense but rather ‘find’ or articulate existing principles within the legal framework. This perspective suggests that judicial precedent is less about creating law and more about refining it, though the practical outcome often blurs this distinction, as new interpretations can significantly alter legal understandings. Thus, while precedent allows judges to influence legal development, their role remains constrained by systemic hierarchies and the need for stability.
Statutory Interpretation as a Form of Law-Making
Another critical area where judges appear to create law is through statutory interpretation. Parliament enacts statutes, but their application often requires judicial clarification due to ambiguous or vague wording. Judges employ various interpretive approaches, such as the literal, golden, and mischief rules, to ascertain parliamentary intent. A notable example is the case of R v Registrar General, ex parte Smith (1991), where the court adopted a purposive approach to interpret legislation in a way that aligned with broader social objectives, arguably extending the law beyond its literal wording.
Moreover, the purposive approach has gained prominence with the UK’s historical integration of European Union law and the incorporation of the European Convention on Human Rights (ECHR) via the Human Rights Act 1998 (HRA). For instance, in Ghaidan v Godin-Mendoza (2004), the House of Lords interpreted the Rent Act 1977 to include same-sex partners under the definition of ‘spouse’, a decision driven by the need to comply with ECHR protections under the HRA. This interpretation effectively expanded legal rights, illustrating a form of judicial law-making. Yet, academics such as Elliott (2001) caution that such decisions are not law creation in the traditional sense but rather a response to statutory obligations and external legal frameworks. Therefore, while statutory interpretation allows judges to shape the law, their role is arguably more reactive than creative, guided by legislative and international constraints.
Influence of Human Rights and European Law
The impact of human rights and European law further complicates the extent to which UK judges create laws. Under the HRA, judges must interpret legislation compatibly with ECHR rights wherever possible, and if compatibility cannot be achieved, they may issue a declaration of incompatibility, as seen in A v Secretary of State for the Home Department (2004). Such declarations do not change the law directly but exert pressure on Parliament to amend legislation, highlighting an indirect law-making influence. Additionally, during the UK’s membership in the EU, judges were bound to apply EU law supremacy over domestic law, as established in Costa v ENEL (1964) by the European Court of Justice, often leading to significant legal shifts in UK jurisprudence.
However, it is essential to acknowledge that post-Brexit, the scope of EU law influence has diminished, with the European Union (Withdrawal) Act 2018 retaining certain EU-derived laws but empowering UK courts to depart from past EU rulings under specific conditions. This shift arguably restores some autonomy to UK judges, potentially enhancing their law-making capacity. Nevertheless, critics such as Gearty (2006) argue that judicial power in human rights and European contexts remains subordinate to parliamentary intent, as Parliament retains the ultimate authority to repeal or amend legislation, including the HRA. Thus, while these frameworks enable judicial influence, they do not equate to independent law creation.
Constraints on Judicial Law-Making
Despite the apparent law-making roles discussed, several constraints limit the extent to which UK judges create laws. Foremost is the principle of parliamentary sovereignty, which ensures that only Parliament can make, amend, or repeal primary legislation. Judicial decisions, even those of significant interpretative weight, can be overridden by subsequent Acts of Parliament, as demonstrated by legislative responses to controversial rulings like Burmah Oil Co Ltd v Lord Advocate (1965), where Parliament retrospectively altered the law via the War Damage Act 1965.
Furthermore, the judiciary’s self-imposed restraint, rooted in the separation of powers, discourages overt law creation. Judges often emphasize their role as interpreters rather than legislators, a view supported by Lord Bingham (2000), who argued that judicial activism must respect democratic principles. This restraint is evident in cases where courts defer complex policy issues to Parliament, such as in Bellinger v Bellinger (2003), where the House of Lords declined to redefine ‘sex’ for marriage purposes, leaving the matter to legislative reform via the Gender Recognition Act 2004. Consequently, while judges can influence legal development, their capacity to create law is circumscribed by constitutional and normative boundaries.
Conclusion
In conclusion, UK judges play a significant role in shaping the law through precedent, statutory interpretation, and engagement with human rights and European frameworks, often blurring the line between application and creation. Landmark cases like Donoghue v Stevenson and Ghaidan v Godin-Mendoza demonstrate how judicial decisions can establish new legal principles or extend existing laws, effectively creating law-like outcomes. However, this influence is heavily constrained by parliamentary sovereignty, judicial restraint, and systemic hierarchies, ensuring that judges operate within a framework of interpretation rather than independent legislation. The implication of this balance is a dynamic yet limited judicial role, where law-making is often incidental rather than intentional. Further exploration into judicial activism versus restraint could deepen understanding of how this balance may evolve, particularly in the post-Brexit legal landscape.
