The letter of formal notice (INFR(2024)2189) was sent to Ireland. The Data Governance Act facilitates data sharing across sectors and EU countries for the benefit of people and companies. It increases trust in data sharing by establishing rules for neutrality of data intermediaries, stimulates voluntary sharing of data and facilitates the reuse of certain data held by the public sector. It has been applicable since 24 September 2023. The competent authorities are in charge for the registration of data altruism organisations (data altruism allows citizens and businesses to give their consent/permission to make available data that they generate for objectives of general interest, for example, medical research projects) and of notification of data intermediation services providers. Ireland has two months to respond and to address the shortcomings raised by the Commission. In the absence of a satisfactory response, the Commission may decide to issue a reasoned opinion.
