The spat between the companies and the Italian government concerned a regulation obliging online service providers operating in Italy to join a register and submit various information as well as pay a financial contribution.
Failure to do so would result in penalties.
Google, Amazon and Airbnb subsequently challenged the rule in an Italian court, saying it was contrary to EU legislation which says online service providers are only subject to the rules of the country where they are established, while countries where they provide a service must refrain from applying their laws.
Both Google and Airbnb have their European headquarters in Ireland and Amazon in Luxembourg. U.S. online travel services provider Expedia also objected to the requirement to provide information.
The Italian court later sought advice from the Luxembourg-based Court of Justice of the European Union (CJEU), Europe’s highest.

CJEU Advocate General Maciej Szpunar said judges should back the tech companies. “A Member State cannot impose general and abstract obligations on an online service provider operating on its territory but established in another Member State,” he said in a non-binding opinion.
The Court, which follows the majority of such recommendations, will rule in the coming months.
The cases are C-662/22 Airbnb Ireland, C-667/22, Amazon Services Europe, Joint Cases C-664/22 Google Ireland, C-666/22 Eg Vacation Rentals Ireland, C-663/22 Expedia and C-665/22 Amazon Services Europe.
