Portugal. Public Competition Enforcement

Tânia Luísa Faria, Margot Lopes Martins, Guilherme Neves Lima.

The Portuguese Competition Authority (PCA) is the independent administrative body in charge of the public enforcement of competition law in all sectors of the Portuguese economy, without exception. In force since 2012, the Portuguese Competition Act (Act) modified the legal standards governing the PCA's handling of complaints, giving the authority greater discretion to decide when to open an investigation based on certain criteria. To increase transparency, at the end of each year, the PCA publishes on its website its strategic priorities regarding competition policy for the following year.
