Uber Technologies Inc. said Monday that it has chosen Cani Fernández, an attorney with deep experience in antitrust, mergers and acquisitions and European Union affairs at international law firm Cuatrecasas, Goncalves Pereira, to argue on its behalf Tuesday in a European Court of Justice hearing that could determine how Uber should be regulated within the European Union.

Fernández, who is based in her firm’s Madrid and Brussels offices, will attempt to persuade Europe’s highest court that the ride-hailing service is not a transportation company, but an app-based service under EU law, meaning that it would not be subject to stricter regulations governing the transportation industry. Fernández, who could not immediately be reached for comment, will be supported by attorneys from French international law firm Gide Loyrette Nouel, according to a source familiar with the matter.
