Spain is marking 40 years since it began formally adapting its national competition system to the rules of the European Economic Community, a process that followed the country's accession to the European Communities in January 1986.

Four decades later, competition policy at EU level is overseen by Spanish politician Teresa Ribera, who serves as Executive Vice-President of the European Commission for a Clean, Just and Competitive Transition and is responsible for the Commission's competition portfolio.

Spain Joined the European Communities in 1986

Spain and Portugal became members of the European Communities on 1 January 1986, increasing the number of member states to 12.

Membership required Spain to bring parts of its national legal and administrative framework into line with Community rules. Competition policy was one of the areas affected by that process.

One important step came later that year with Royal Decree 1882/1986.

The 1986 Competition Decree

The decree was approved by the Council of Ministers on 29 August 1986 and published in the Official State Gazette on 15 September.

Its purpose was to establish how the Community's competition rules would be applied in Spain and how Spanish authorities would cooperate with the European Commission.

The measure specifically addressed Articles 85 and 86 of the EEC Treaty, which dealt with restrictive agreements and abuses of dominant positions.

The decree did not create those European competition prohibitions. Instead, it established the national framework for applying them in Spain.

New Responsibilities for Spanish Authorities

The legislation designated the Tribunal de Defensa de la Competencia as a competent authority for applying the relevant Community rules in Spain.

It also gave the Dirección General de Defensa de la Competencia responsibility for cooperation between the Spanish administration and the Commission of the European Communities.

The framework included procedures for inspections requested by the Commission, including access to company premises and professional documents under the conditions established by the legislation.

Cooperation With Brussels

The 1986 rules also established what would happen when the European Commission required verification activity in Spain.

Spanish officials could assist Commission officials with those inspections, while the regulation provided for assistance from Spain's security forces if a company opposed a verification.

At the same time, information obtained through the procedures was protected by professional secrecy and could only be used for the purpose for which it had been requested.

From EEC Rules to EU Competition Law

The legal framework has changed substantially since 1986.

The EEC Treaty provisions referred to in the decree were subsequently renumbered as European integration developed. The modern EU competition framework includes Article 101 of the Treaty on the Functioning of the European Union, which prohibits agreements and practices that restrict competition, and Article 102, which prohibits abuse of a dominant position where the conditions of the treaty are met.

The European Commission and national competition authorities now work together to enforce these rules across the EU.

Teresa Ribera's Role in Brussels

The 40th anniversary has a notable Spanish connection.

Teresa Ribera has been an Executive Vice-President of the European Commission since the current Commission took office on 1 December 2024. Her portfolio is titled Clean, Just and Competitive Transition and includes responsibility for modernising EU competition policy.

Her responsibilities include competition enforcement, merger control and state-aid policy, alongside the wider economic and industrial elements of her portfolio.

Competition Policy Today

EU competition policy now covers a much broader and more complex economic environment than the one Spain entered in 1986.

The Commission enforces rules against cartels and other anti-competitive agreements, investigates possible abuses of dominant positions and assesses mergers with a European dimension.

It also examines state aid granted by member states and applies competition rules to evolving areas of the economy, including digital markets and strategic industries.

The Commission is also currently reviewing its Merger Guidelines, with the process scheduled to continue through the final quarter of 2026.

A Legal Milestone Four Decades On

The anniversary provides a snapshot of how Spain's role in European competition policy has changed.

In 1986, the priority was establishing the domestic institutions and procedures needed to apply Community competition law after accession.

Today, Spanish authorities operate within the EU's integrated competition system, while a Spanish member of the European Commission holds political responsibility for the competition portfolio at EU level.

The institutional framework has evolved considerably, but the 1986 decree remains an important milestone in the process by which Spain incorporated European competition rules into its national system.
