Best Antitrust Litigation Lawyers in Santo Tirso

1. About Antitrust Litigation Law in Santo Tirso, Portugal

Antitrust litigation in Portugal focuses on prohibiting agreements that restrict competition, abuses of a dominant position, and other anti-competitive conduct. The national authority in charge is the Autoridade da Concorrência (AdC), which investigates suspected infringements and can impose penalties. Private lawsuits for damages are also possible in Portuguese civil courts when competition rules are violated.

In Santo Tirso, as in the rest of Portugal, individuals and small to large businesses can pursue remedies either through AdC investigations or through civil actions for damages in local courts. Private actions often involve demonstrating that a competitor's conduct caused measurable harm to your business or consumer interests. A Portuguese competition lawyer can help connect the dots between public enforcement and private damages.

Public enforcement and private actions can run in parallel. AdC findings may support civil claims, while a private suit can seek damages, interest, and costs. This dual path is common in Portugal when a cartel, abuse of dominance, or restrictive agreement affects local suppliers or buyers in Santo Tirso and the Porto district.

3. Local Laws Overview

Portugal applies both national and EU competition law. The domestic framework historically rests on the Lei da Concorrência and related regulations, while EU competition rules also bind Portuguese practice given Portugal's EU membership. Local litigation can involve civil claims framed under general civil liability principles for damages caused by anti-competitive conduct.

Key domestic references commonly cited in Portuguese practice include the general competition regime and its implementing provisions, often discussed alongside EU Regulation and guidance. In Santo Tirso, lawyers frequently rely on these statutes to steer private actions through the civil courts in the Porto district and to align with AdC investigations.

• Decree-Law governing the Portuguese competition regime (historical cornerstone of domestic competition law) - used as context for understanding the modern framework and private enforcement.
• Lei da Concorrência (Law governing competition in Portugal) - referenced in reform discussions and used by practitioners to frame anti-competitive claims in civil litigation.
• EU competition rules and Regulation (for example, EU competition law on cartels, abuses of dominance, and merger control) - applicable through the court system and enforcement cooperation with AdC.
