Amazon in a Luxembourg court Tuesday contested a once-record privacy fine levied against the e-commerce giant for its advertising practices by the diminutive country’s data protection authority.

At the hearing in Luxembourg’s administrative court, Amazon lawyer Thomas Berger accused the Luxembourg regulator of attacking the company based on unfound allegations, Bloomberg reported. Amazon’s European headquarters is in the country.

The fine of 746 million euros stems from French privacy group La Quadrature du Net’s 2018 complaint alleging that Amazon Europe and its British subsidiary Amazon Video Limited relied on terms and conditions that wrongly interrupted the legal basis for consent and data collection to process its customer data for ad personalization, violating consent and transparency requirements under the General Data Protection Regulation.
