International Law Influence Appeal Decisions in Australian Courts
The convergence of international law and domestic legal frameworks has been a contentious issue in Australia's legal system for years. With globalisation on the rise and international treaties gaining prominence, the question is: can international law affect appeal rulings in Australian courts? The response is complex, with legal principles, precedents, and policy factors that shape the outcome of litigation. This article discusses the influence of international law on appeal judgments in Australia, with special reference to major cases, doctrines of law, and judicial arguments.
The Role of International Law in the Australian Legal System
International law comprises treaties, conventions, and customary principles of international law that regulate international relations between states. Being a signatory to various international treaties, Australia is subject to international law, but its influence on domestic appeal judgments is complicated. The High Court of Australia has consistently ruled that international law does not per se form part of Australian law unless it is engrafted by domestic legislation. Yet, courts continue to refer to principles of international law in their judgments, especially in spheres like human rights, environmental jurisprudence, and trade disputes.
Chief Ways International Law Affects Australian Appeals
International treaties and conventions are used by courts to interpret unclear provisions in the domestic law.
The doctrine of consistency requires that Australian law, where practicable, be interpreted in conformity with international legal commitments.
Common Law Development
The High Court and appellate courts have drawn on international law to influence the development of the common law.
Principles of human rights, for instance, have informed judicial interpretations in the interpretation of cases concerning basic freedoms and procedural fairness.
A landmark case in which the High Court held that ratified international agreements could give rise to a 'legitimate expectation' that the government would behave in accordance with them, even if not formally enshrined in law.
The case had a major influence on the way courts determine procedural fairness in administrative review.
The High Court addressed international law principles of citizenship and Indigenous identity.
The decision made it clear that Indigenous Australians could not be regarded as "aliens" in the Constitution, partly due to international human rights standards.
Obstacles in Enforcing International Law in Appeals
International law can be powerful, but there are a number of obstacles in enforcing it in appeal cases:
Domestic Sovereignty vs. International Obligations
Australian courts have to balance international obligations against constitutional and legislative provisions.
Courts are reluctant to overrule domestic legislation on the basis of international legal rules alone.
Variability in Judicial Interpretation
Various courts may have different interpretations of the applicability of international law, hence incurring inconsistent results in appeals.
Lack of Direct Enforceability
International treaties are not automatically legally enforceable unless they are incorporated into Australian legislation.
Courts can apply them as a guiding factor, but not as legally enforceable principles in most instances.
How International Law Influences Future Litigation Trends
As there is more global legal integration, Australian courts can expect increased international law reference in subsequent appeals. The major trends are:
Climate Litigation: Climate-related cases may be affected by appeal decisions influenced by international environmental agreements.
Human Rights Litigation: Increased application of international human rights treaties in refugee matters, discrimination claims, and family law.
Trade and Investment Disputes: With increasing international trade agreements undertaken by Australia, international trade law will resonate through commercial litigation and appeals.
Australian courts are not bound by international law per se, but it plays a significant part in determining appeal judgments, especially in statutory construction, common law evolution, and human rights. Courts reconcile national legal sovereignty and international legal concepts to keep Australia in sync with international commitments as well as abide by domestic law. With increased globalisation of legal challenges, the relationship between international law and Australian litigation will keep changing.
