Judges at the European Union Court of Justice in Luxembourg are deliberating on whether Uber Technologies should be considered an app or a transport company, Bloomberg reported.

The decision, which could be months away, will impact disputes the company is facing in several European countries.

The ruling will only affect UberPop services, which lets unlicensed drivers use their own car to pick up riders for low fees, and not other products such as UberX.

If the judges deem it a transport company, Uber will have to adhere to stricter licensing rules, with more operating costs and potentially fewer drivers as far as UberPop goes.

UberPop has already been halted in several European countries, including France, the Netherlands and Sweden.

Uber, of course, wants to be thought of as an app. As one of its lawyers, Cani Fernandez, told the judges, its activities “cannot be reduced to a mere transport activity”.

“Electronic intermediation is a service in itself and it’s separate from the final service for which the user and the provider are being connected,”  he said. Such services could include “transport or the home delivery of food, or any other type of service imaginable which can be provided by means of an Uber platform”.

Meanwhile, Montse Balague Farre, a lawyer representing Spain’s Asociacion Profesional Elite Taxi, told the EU court: “If there’s a transport service being provided, a company should not be able to hide behind the thin veil of describing it as a different kind of activity.”

“We cannot allow a business model to develop in Europe which could allow for any undermining or detriment to the rights and protection of consumers,” she said, adding that Uber gets around having to obtain an administrative authorisation and pay about €150,000.

Uber is allowed in some Spanish cities like Madrid but is banned in Barcelona.

Meanwhile in the US, Uber and Lyft have hailed President-elect Donald Trump’s decision to nominate Elaine Chao for transportation secretary, as she has in the past publicly supported their business model.
