Supreme Court to hear appeal on preliminary issues arising in LinkedIn challenge to €310m DPC fine

The Supreme Court will hear an appeal by the Data Protection Commission (DPC) relating to certain preliminary matters arising in LinkedIn’s challenge to the imposition of a €310 million fine by the commission. In October 2024, the DPC fined LinkedIn €310 million for breaches of European data protection legislation. In a judgment handed down in April, the High Court determined several preliminary issues in the proceedings. The DPC has appealed to the Supreme Court on three such issues decided on by the High Court. LinkedIn also seeks to bring a cross-appeal on another preliminary issue.
