Free movement of services and establishment

Free movement of services and freedom of establishment form the economic counterpart to the free movement of workers and citizens considered in Week 6. They concern the movement of economic activity rather than merely the movement of persons. Establishment protects the stable and continuous pursuit of self-employed activity in another Member State. Services protect temporary cross-border economic activity, whether the provider moves, the recipient moves, both move, or only the service itself crosses a border.

The provisions now found in Articles 49 to 55 TFEU and Articles 56 to 62 TFEU are central to the internal market. They are also doctrinally important because the Court of Justice used them to develop the modern vocabulary of restriction, market access, imperative requirements in the general interest, proportionality, and mutual recognition. The structure will be familiar from goods and persons, but the details differ. Goods law has the Keck detour; persons law has the categories of worker, citizen and economically inactive person; services and establishment sit between those fields. They protect economic actors but often require close attention to the organisation of regulated professions, licences, concessions, corporate law, taxation, health care, gambling, education, broadcasting and digital platforms.

A Cambridge answer should not treat services and establishment as one undifferentiated freedom. The first task is classification. Is the activity temporary or stable? Is the actor self-employed, employed, or a company? Is the restriction imposed by the host State, the home State, a professional body, or a private association capable of regulating access to the market? The second task is to identify the type of impediment: direct discrimination, indirect discrimination, a dual regulatory burden, an authorisation scheme, a professional qualification rule, a corporate law requirement, or a measure which simply makes cross-border activity less attractive. The third task is justification. Express Treaty derogations are narrow; judge-made public-interest justifications are broader for indistinctly applicable measures; all must satisfy proportionality.

For Tripos purposes, the topic is often examined through problem questions involving professional regulation, licensing, advertising, gambling, health services, corporate migration, or post-Brexit consequences in UK law. Essays tend to ask whether the Court has moved from non-discrimination to market access, whether the Gebhard formula is too expansive, whether company mobility cases undermine national regulatory autonomy, or whether services law represents mutual recognition or judicial deregulation. The best answers connect doctrine to principle: the internal market is not a licence for economic libertarianism, but neither is it compatible with national rules that duplicate burdens, conceal protectionism, or reserve economic opportunity to insiders.

The original EEC Treaty was built around the abolition of barriers to trade and factor mobility. Goods were the most visible field, but establishment and services were equally ambitious. The founding premise was that nationals of one Member State should be able to pursue self-employed activity across the Community and that temporary economic services should not be confined by national frontiers. The Treaty initially envisaged staged liberalisation, with Council programmes and directives removing restrictions sector by sector. That legislative technique proved slow. As in other fields of EU law, judicial enforcement supplied momentum.

The early cases established the constitutional foundations. Reyners confirmed that Article 52 EEC, now Article 49 TFEU, had direct effect after the transitional period. A Belgian rule excluding non-Belgians from the legal profession could no longer be defended by delay in legislative implementation. Van Binsbergen did the same for services: a Dutch residence requirement imposed on a legal representative restricted the freedom to provide services. These cases matter because they transformed Treaty freedoms from political programme into enforceable rights. They also prefigured later disputes over professional regulation, residence requirements and the boundary between legitimate supervision and exclusionary control.

The 1980s and 1990s saw the Court move beyond nationality discrimination. In goods, Cassis de Dijon had already introduced mutual recognition and mandatory requirements. In services, Säger held that Article 56 prohibits not only discrimination but also non-discriminatory restrictions liable to prohibit or impede the activities of a provider established in another Member State. Gebhard then supplied a general four-part test for national measures liable to hinder or make less attractive the exercise of fundamental freedoms: non-discrimination, public-interest justification, suitability and necessity. This formula became one of the organising propositions of internal market law.

The legislative background also developed. Sectoral directives on lawyers, doctors, architects and financial services were supplemented by more general mutual recognition rules for professional qualifications. The Services Directive 2006/123/EC attempted a broader rationalisation of authorisation schemes, administrative burdens and discriminatory requirements. It was politically controversial because an earlier country-of-origin proposal was perceived as threatening domestic labour and welfare regulation. The final Directive is less radical: it combines simplification, prohibited requirements and proportionality review, while excluding areas such as healthcare, financial services, transport and certain social services.

Company mobility produced a parallel line of authority. Centros, Überseering and Inspire Art enabled companies formed in one Member State to exercise establishment rights elsewhere, even where incorporation was chosen to take advantage of lighter company law. These cases privileged incorporation and mutual recognition over real-seat theories, subject to abuse and public-interest controls. Later cases such as Cartesio, Vale and Polbud refined the distinction between inbound recognition, outbound conversion and the continuing power of the state of incorporation to define its own connecting factors.

For UK lawyers the historical context has an additional layer. Before withdrawal, Articles 49 and 56 TFEU were directly effective and capable of disapplying inconsistent domestic rules. After Brexit, the operative position depends on retained or assimilated EU law, the Withdrawal Act, the Retained EU Law (Revocation and Reform) Act 2023, and the circumstances in which pre-withdrawal CJEU case law remains relevant. Cambridge EU Law still examines the classical law because it is foundational to understanding the internal market, because much domestic law was made in its shadow, and because questions about retained EU law require knowledge of the content and method of EU doctrine before withdrawal.

1. Establishment and services must be distinguished, but not artificially separated. Establishment involves actual pursuit of an economic activity through a fixed establishment in another Member State for an indefinite period. Services are residual and temporary. Article 57 TFEU defines services as activities normally provided for remuneration, insofar as they are not governed by goods, capital or persons. Temporariness is assessed not only by duration but also by regularity, periodicity and continuity. A consultant who spends two days in France advising a client is ordinarily providing a service. A dentist opening a permanent clinic in France is exercising establishment. A company incorporated in the Netherlands but conducting much of its business through a branch in Belgium may rely on establishment.

1. The freedoms apply to nationals of Member States and to companies formed in accordance with the law of a Member State and having their registered office, central administration or principal place of business within the Union. Companies are therefore treated as Treaty beneficiaries. The corporate cases are not an eccentric appendix; they are a major part of establishment law. They show that establishment covers both primary establishment, such as setting up a company, and secondary establishment, such as agencies, branches and subsidiaries.

1. The protected activity must be economic. Remuneration is interpreted broadly. It need not be paid by the recipient personally: medical treatment, education, broadcasting and online services may be economic where funded through insurance, public schemes, advertising or subscriptions. By contrast, activities connected with official authority are excluded under Article 51 TFEU, and non-economic welfare functions may fall outside the Treaty freedoms. The Court construes the official-authority exception narrowly. It is not enough that a profession is regulated, socially important, or participates in administration; the activity must involve direct and specific participation in the exercise of official authority.

1. Direct discrimination is the easiest case. Nationality requirements, residence requirements operating as nationality proxies, and rules reserving professions to nationals of the host State are prima facie unlawful. They may be saved only by express Treaty derogations such as public policy, public security and public health, or by Article 51 where official authority is genuinely involved. The derogations are strictly construed. A blanket nationality rule for lawyers was not saved in Reyners merely because some lawyers perform functions connected to the administration of justice.

The development begins with direct effect. Reyners v Belgium rejected the idea that the freedom of establishment depended indefinitely on legislative implementation. Once the transitional period had expired, the prohibition on nationality discrimination in access to self-employed activity was sufficiently clear to be enforced. The Court also treated the official-authority exception as narrow. The legal profession as a whole could not be removed from Article 49 merely because some legal functions are connected with the courts.

Van Binsbergen performed the same constitutional role for services. A residence requirement imposed on a legal representative before a Dutch tribunal was capable of preventing a provider established in another Member State from offering services. The Court accepted that some requirements might be justified to ensure professional conduct and effective supervision, but a general residence requirement was suspect. The case is important because it recognised both direct effect and the possibility of non-discriminatory regulatory justification.

Säger v Dennemeyer marks the decisive move from discrimination to restriction. A German rule reserved patent renewal services to authorised patent agents. The service provider, established in the United Kingdom, did not require the same professional qualification for the administrative service in question. The Court held that Article 56 catches measures which impede or render less advantageous cross-border services even if they apply without distinction. It also framed the proportionality inquiry: professional rules may be justified by the public interest, but the host State must show that the restriction is necessary and that the interest is not already protected by the provider’s home-state rules.

Gebhard is the canonical statement of the general test. A German lawyer practising in Italy was disciplined for using the title avvocato and operating chambers. The Court distinguished establishment from services by reference to stable and continuous participation in the economic life of the host State, but its real significance lies in the four conditions for restrictions on fundamental freedoms. The case is routinely cited in problem questions; it should be applied, not merely named.

Alpine Investments extended services law to home-state restrictions. The Netherlands prohibited cold-calling in relation to commodity futures. The provider was established in the Netherlands and wanted to contact potential clients in other Member States. The Court held that Article 56 applied: the home State can restrict export of services. The restriction was justified by consumer protection and reputation of the financial sector. The case shows that Article 56 is not simply about hostile host States.

Gambelli and later gambling cases illustrate deference and coherence. Criminal penalties and licensing monopolies may restrict services, especially where betting services are supplied from another Member State. Member States may rely on consumer protection, fraud prevention and public-order concerns. But the Court asks whether the policy is genuinely aimed at reducing gambling opportunities or instead pursues revenue while excluding foreign operators. Moral sensitivity does not exempt the State from proportionality.

Centros and Inspire Art are the leading company mobility cases. They hold that a company validly incorporated in one Member State may rely on establishment to set up a branch and conduct business in another, even where the founders chose the first State for more favourable company law. Regulatory arbitrage is not automatically abuse. Host States may combat fraud and protect creditors, but blanket refusal to register or the imposition of duplicative capital requirements is difficult to justify. These cases are controversial because they constitutionalise a form of corporate mobility and limit real-seat regulatory strategies.
