The book provides extensive coverage of the EU AI Act and its broader regulatory context, addressing the rapid emergence of governance frameworks at international, European and national levels.
It examines, among others:

- An article-by-article analysis of the proposed EU AI Liability Directive
- Core regulatory principles such as fairness, transparency, human-centredness and trustworthiness
- The use of publicly available data for AI training under the GDPR
