Van Gend en Loos (1963): Establishing the Principle of Direct Effect in EU Law
“EU treaties aren’t just agreements between states. They confer rights directly on individuals.” That revolutionary statement is the essence of Van Gend en Loos.
Hello, readers interested in European law. When I first studied Van Gend en Loos (1963), my first reaction was honestly, “Can they really say that?” A dispute by a Dutch haulier over customs duties ended up redefining the nature of European Union law. The case established the principle of direct effect: EU treaty provisions are not merely intergovernmental promises; they grant rights that individuals and companies can invoke before national courts. Let’s unpack this landmark judgment.

Background and Facts
The Dutch carrier Van Gend en Loos imported a chemical from Germany into the Netherlands. Dutch customs imposed a new duty. The company argued this breached Article 12 of the EEC Treaty, which prohibited Member States from introducing new customs duties (or increasing existing ones). The unresolved question was whether an individual could rely directly on that treaty provision in court. The Dutch court referred the issue to the Court of Justice of the European Union (CJEU).
Key Issue: Direct Effect of Treaty Provisions
The core issue was whether a provision of the EEC Treaty conferred rights directly on individuals, such that national courts must protect those rights. Put differently, was the treaty merely an agreement among states, or a body of law that individuals could invoke?
| Party | Position | Core Rationale |
|---|---|---|
| Van Gend en Loos | Direct effect applies | Article 12 prohibits new customs duties and confers a right that individuals can rely on |
| Dutch Government | Direct effect denied | The treaty is an agreement between Member States only; individuals cannot directly invoke it |
The Court’s Judgment and Reasoning
The CJEU delivered a groundbreaking ruling: Article 12 was not merely a state-to-state obligation; it conferred rights on individuals. The Court thereby articulated, for the first time, the principle of direct effect. The key reasoning:
- EU treaties form part of a legal order—not just political declarations.
- Individuals can rely on treaty provisions to assert rights.
- National courts must apply and protect those rights.
Impact on the EU Legal Order
Van Gend en Loos is viewed as a constitutional moment for EU law. Individuals and companies could now assert treaty-based rights directly, without waiting for state action. This moved beyond a sovereignty-only conception toward the EU as a “new legal order”. The principle was soon reinforced in later cases—most famously, Costa v. ENEL.
Criticism and Academic Debate
Critics argue the Court engaged in judicial activism by creating a doctrine not expressly stated in the treaty. Supporters counter that without such a ruling, EU law would lack the binding force necessary for integration. In short:
| Perspective | Main Argument |
|---|---|
| Critical view | The judiciary created legal principles beyond the treaty’s text |
| Supportive view | The ruling gave EU law real effectiveness and accelerated integration |
Contemporary Significance and Takeaways
Van Gend en Loos remains a staple of EU law courses and research. It anchored the EU’s identity not as a mere association of states but as a legal community. Its significance includes:
- The first case to articulate the principle of direct effect
- Opened the path for individuals and companies to invoke EU treaties in national courts
- Framed the constitutional character of EU law and laid groundwork for its supremacy

In Closing
Van Gend en Loos (1963) was a true game-changer. The idea that treaties grant rights directly to individuals was bold then and remains a pillar of the EU’s legal identity now. When studying, keep a checklist of the direct-effect criteria—clarity, unconditionality, and sufficient precision—and case application becomes much easier. If conflicts with domestic law come to mind, share them. We can connect the dots to Costa v. ENEL and see how this “new legal order” operates in practice. 🙂
