A Dutch national was refused entry to the UK to work for the Church of Scientology, which the UK government considered socially harmful. The ECJ ruled that Article 48 EEC Treaty and Directive 64/221 have direct effect, allowing individuals to rely on them in national courts, while Member States retain discretion on public policy grounds.
Facts
Yvonne van Duyn, a Dutch national, sought to enter the United Kingdom to take up employment as a secretary with the Church of Scientology. The UK Home Office refused her leave to enter in accordance with the government’s policy regarding the Church of Scientology, whose activities it considered socially harmful. Van Duyn brought proceedings in the Chancery Division of the High Court of Justice, which referred three questions to the European Court of Justice for a preliminary ruling under Article 177 of the EEC Treaty.
Issues
First Issue: Direct Effect of Article 48 EEC Treaty
Whether Article 48 of the EEC Treaty is directly applicable so as to confer on individuals rights enforceable in the courts of a Member State.
Second Issue: Direct Effect of Directive 64/221
Whether Council Directive 64/221, particularly Article 3(1), is directly applicable so as to confer on individuals enforceable rights.
Third Issue: Personal Conduct and Public Policy
Whether a Member State, when imposing restrictions on grounds of public policy, can take into account an individual’s association with an organisation considered socially harmful but not unlawful, even where no similar restrictions apply to its own nationals.
Judgment
On the First Question
The Court held that Article 48 has direct effect. The provisions impose a precise obligation on Member States requiring no further measures for implementation and leaving no discretionary power.
THE APPLICATION OF THESE LIMITATIONS IS, HOWEVER, SUBJECT TO JUDICIAL CONTROL, SO THAT A MEMBER STATE’S RIGHT TO INVOKE THE LIMITATIONS DOES NOT PREVENT THE PROVISIONS OF ARTICLE 48, WHICH ENSHRINE THE PRINCIPLE OF FREEDOM OF MOVEMENT FOR WORKERS, FROM CONFERRING ON INDIVIDUALS RIGHTS WHICH ARE ENFORCEABLE BY THEM AND WHICH THE NATIONAL COURTS MUST PROTECT.
On the Second Question
The Court established that directives can have direct effect in certain circumstances, rejecting the UK’s argument that directives inherently lack such effect.
IT WOULD BE INCOMPATIBLE WITH THE BINDING EFFECT ATTRIBUTED TO A DIRECTIVE BY ARTICLE 189 TO EXCLUDE, IN PRINCIPLE, THE POSSIBILITY THAT THE OBLIGATION WHICH IT IMPOSES MAY BE INVOKED BY THOSE CONCERNED.
The Court ruled that Article 3(1) of Directive 64/221 confers directly enforceable rights on individuals.
On the Third Question
The Court held that present association with an organisation may constitute personal conduct justifying public policy restrictions. Regarding the interpretation of public policy:
THE CONCEPT OF PUBLIC POLICY IN THE CONTEXT OF THE COMMUNITY AND WHERE, IN PARTICULAR, IT IS USED AS A JUSTIFICATION FOR DEROGATING FROM THE FUNDAMENTAL PRINCIPLE OF FREEDOM OF MOVEMENT FOR WORKERS, MUST BE INTERPRETED STRICTLY, SO THAT ITS SCOPE CANNOT BE DETERMINED UNILATERALLY BY EACH MEMBER STATE WITHOUT BEING SUBJECT TO CONTROL BY THE INSTITUTIONS OF THE COMMUNITY.
The Court acknowledged that Member States retain discretion, as circumstances justifying recourse to public policy may vary between countries and time periods. A Member State is not required to make activities unlawful before relying on public policy. Furthermore, the principle of international law that a state cannot refuse entry to its own nationals means differential treatment of nationals and non-nationals in this context is permissible.
Implications
This case is foundational in EU law for several reasons. It confirmed the direct effect of Treaty provisions granting free movement rights. More significantly, it extended the principle of direct effect to directives, establishing that where directives impose clear, unconditional obligations requiring no further implementation, individuals may rely upon them in national courts. This significantly enhanced the effectiveness of EU law and individual rights protection. The case also clarified the scope of the public policy exception, establishing that while it must be interpreted strictly and subject to Community control, Member States retain necessary discretion in its application.
Verdict: The Court ruled that: (1) Article 48 EEC Treaty has direct effect and confers enforceable rights on individuals; (2) Article 3(1) of Directive 64/221 has direct effect and confers enforceable rights on individuals; (3) A Member State may take into account an individual’s association with an organisation considered socially harmful (though not unlawful) as personal conduct justifying public policy restrictions, even where no similar restriction applies to its own nationals.
