Ireland: Dublin Circuit Court confirms fine by the Irish Data Protection Commission imposed on Twitter over Data Protection Act infringement

On 18 October 2021, the Dublin Circuit Court confirmed the fine handed out by the Irish Data Protection Commission (DPC) on 9 December 2020 when it sanctioned Twitter for infringements of Articles 33(1) and 33(5) of the Irish General Data Protection Regulation (GDPR). Twitter has to pay an administrative fine of €450,000 for its failure to notify the data breach on time and for failing to correctly document the breach. Following an inquiry, the agency found that the company should have known of the breach by 3 January 2019 but only reported the breach to the DPC on 8 January 2019.
