Solidarity at the intersection of data sharing and data protection: A normative analysis

This article examines the role of solidarity in shaping evolving EU data-sharing policies, with a focus on the Data Governance Act. It seeks to demonstrate how solidarity can articulate the boundaries of the concept of ‘general interest’, guide proportionality assessments in data-sharing decisions and inform harm mitigation strategies. The analysis reveals that solidarity not only broadens the understanding of general interest by emphasizing its collective benefits but also provides safeguards for societal vulnerabilities. In cases of tension, solidarity ensures that general interests are pursued while prioritizing the need to prevent and mitigate harm. Concluding, the article argues that solidarity offers a vital framework for reconciling the competing demands of data sharing and data protection by promising a balanced approach to the EU's evolving data governance landscape.
