The legal challenge has been brought by The French Association of Internet Community Services (ASIC) and relates to government plans to keep web users’ personal data for a year.
The law obliges a range of e-commerce sites, video and music services and webmail providers to keep a host of data on customers.
ASIC head Benoit Tabaka believes that the data law is unnecessarily draconian. “Several elements are problematic,” he said.
“This is a shocking measure,” added Mr Tabaka.
