The European Court of Justice (the highest court in Europe) held that Uber is a transportation service, which may therefore be regulated by each country in Europe. The ECJ explained:
The service provided by Uber connecting individuals with non-professional drivers is covered by services in the field of transport. Member states can, therefore, regulate the conditions for providing that service.
In contrast, Uber had argued that the company was an information technology service, subject only to Europe-wide regulation and exempt from national law.
