Liability for Loss and Corruption of Data

Publication date: October 05, 2026

The loss or corruption of data in a business is rarely “just” a technical problem. In practice it is a serious legal and financial crisis: production downtime, loss of trust among business partners and, in extreme cases, administrative fines running into millions.

The Convention thus constitutes an important point of reference both for domestic courts and for international tribunals. Many States also regard the Convention as binding to the extent that it codifies customary law already existing in this area.

This article sets out the relationship between the GDPR and the AI Act: from the roles of provider, deployer and controller, through algorithmic risks, the limits of lawfulness in the workplace and the rights of individuals, to the DPIA, the FRIA and the AI Governance model. It reflects the legal position following the entry into force of the Polish Act on Artificial Intelligence Systems and the postponement of the AI Act application dates by Regulation (EU) 2026/1744.
