Social media giant TikTok has been granted permission by the High Court to mount a legal challenge against what it argues is the "penal" €530m fine imposed upon it by the Data Protection Commissioner (DPC) over the alleged transfer of site-users' personal data to China.

TikTok is facing a fresh European Union privacy investigation into user data transferred to China. The Irish Data Protection Commission opened the inquiry as a follow up to a previous investigation that ended earlier this year with a 530 million euro fine.

Ireland's powerful Data Protection Commission (DPC) has opened a new inquiry into TikTok over the storage of European users' data in China after the short-video platform disclosed in April that some data had temporarily been stored on Chinese servers.
