BRUSSELS — A group of European Parliament lawmakers is pressing the European Commission to look into FIFA’s ticket-selling tactics for the World Cup, amid concerns these could violate EU competition and consumer protection rules.

The group of 23 lawmakers, mainly from the center-left of the Parliament, warn that FIFA, “as the exclusive primary seller of World Cup tickets … may hold a dominant position in the downstream ticket sales market.”

The lawmakers ask the Commission whether it sees the practices as a “potential abuse of a dominant position” and if consumers can make an informed purchasing decision, as they “may be deprived of essential information,” according to a set of written questions seen by POLITICO.

They refer to a complaint filed last week by Euroconsumers and Football Supporters Europe, which claimed that world football governing body FIFA “abused its monopoly position to impose excessive ticket prices and opaque and unfair purchasing conditions.”

The groups took aim at the practice of “dynamic pricing,” which means that costs fluctuate based on demand. Fans had “no clear way of knowing the final price before joining the queue,” the groups said.

European Parliament lawmakers also want to know whether the Commission will include a ban on dynamic pricing for live-event tickets in its upcoming online consumer protection rulebook, known as the Digital Fairness Act.

Italian Social Democrat Brando Benifei urged the Commission to “use now all existing legal instruments to protect our customers and prepare to fill the existing loopholes.”

That law is expected to land this year and is designed to update EU consumer rules for the digital age.
