Competition & Antitrust Law in Greece

Competition and antitrust law in Greece is the professional legal and regulatory function through which commercial agreements, market conduct and concentration events are assessed under Law 3959/2011 on the Protection of Free Competition and related Greek and EU rules. Hellenic Competition Commission is the central authority.

Greek competition analysis begins with commercial facts: the parties, relevant markets, agreement terms, pricing, market shares, customer alternatives, worldwide and Greek turnover, transaction structure and internal decision records. Matters may concern cartels, vertical restraints, abuse of dominance, merger control, media-sector transactions or authority investigation.

Greece is an EU Member State. Greek competition law operates alongside Articles 101 and 102 TFEU where conduct may affect trade between Member States, while qualifying transactions may be reviewed by HCC or the European Commission depending on applicable jurisdictional thresholds.

A distinctive Greek feature is the split between standard merger thresholds and lower informative-media thresholds. Transaction teams should determine early whether the parties operate in a relevant informative-media market and whether the special notification regime applies.

This section defines the practical boundaries of the Competition & Antitrust Law Registry Object. It distinguishes Greek competition law from broader commercial, consumer, media, sector-regulatory, public-procurement and corporate work that may connect to a matter without forming its primary competition-law issue.

The purpose of Greek competition and antitrust law is to preserve effective competition and prevent harmful agreements, abusive market conduct and concentrations that may significantly impede competition.

The professional function translates commercial strategy into legally assessed conduct so businesses can identify risk before it becomes HCC investigation, fine, remedy, transaction delay or litigation exposure.

Request contexts show the situations in which Greek competition-law work is typically activated.

Greece combines EU competition-law integration with a national turnover-based merger-control regime and distinct treatment for informative-media concentrations. This requires early classification of the transaction and careful separation of standard merger review from special media-sector review.

Greek competition enforcement is centred on Hellenic Competition Commission. HCC investigates restrictive practices, abuse of dominance and qualifying concentrations, while the European Commission remains relevant to EU-wide competition and merger matters.

The principal Greek framework is Law 3959/2011 on the Protection of Free Competition. Articles 5 to 10 contain the principal merger-control regime, while special legislation applies to informative-media concentrations.

Greek competition-law work normally proceeds from commercial fact collection to market assessment, legal classification, HCC jurisdiction analysis, merger or investigation planning and continuing compliance monitoring.

The decision tree simplifies threshold questions that commonly determine the correct Greek competition-law route.

1. Identify whether the issue concerns an agreement, conduct, information exchange, market power, transaction or informative-media operation.
2. Confirm the affected Greek markets, parties, worldwide turnover, Greek turnover and commercial effects.
3. Assess whether Greek law, EU law or both apply.
4. Determine whether the standard merger thresholds or special informative-media thresholds apply.
5. Review commercial records, internal communications and objective business rationale.
6. Implement the appropriate legal and operational path before conduct begins or a transaction closes.

Greek competition issues commonly arise before implementation and may continue through HCC merger review, media-merger procedure, investigation, remedies, court process or EU-level coordination.

Greek competition analysis depends on reliable documentation of commercial facts, market structure, worldwide and Greek turnover, media status, agreement terms, transaction arrangements and internal decision-making.

Greece is an EU Member State and a commercially connected southeastern European jurisdiction. Greek competition matters frequently require coordination with EU rules, European Commission jurisdiction and the competition regimes of other affected Member States.

Operating constraints identify the recurring risks that can affect competition-law execution in Greece.

The cost profile of Greek competition matters depends on market complexity, turnover and media-sector analysis, document volume, notification requirements, HCC procedure and EU coordination.
