GA‑Alliance, an international law and tax firm operating in 80 countries with more than 2,600 professionals, announces the appointment of Roberto Mastroianni as of counsel, effective 15 March 2026. This appointment strengthens the firm’s ability to handle complex European litigation and antitrust matters with a high-level institutional and technical perspective.

Professional and academic profile

Roberto Mastroianni is a full professor of European Union Law at the University of Naples Federico II. His career combines international academic experience with senior institutional roles: he served as a Judge and Presiding Judge of a Chamber at the General Court of the European Union in Luxembourg (2019–2025) and has held positions as a référendaire at the Court of Justice of the European Union and as Counsellor for Legislative Affairs at the Department for European Affairs of the Italian Prime Minister’s Office.

His academic training includes a law degree from Florence (1987), an LL.M. from Penn State University (1990) and a PhD from Bologna (1992), with further study at institutions such as the University of Geneva, the University of Amsterdam and New York Law School. He has taught at numerous universities in Italy and abroad, including LUISS, Paris 2 Panthéon‑Assas and American University.

Distinctive expertise and practice areas

Throughout his career, Professor Mastroianni has maintained an active litigation practice, authorised to appear before Italy’s highest courts and European courts for more than twenty‑five years. His experience is particularly notable in competition law as applied to the Media and TMT sectors, and in regulatory issues related to the digital single market.

Mastroianni brings to GA‑Alliance a rare combination of the judicial decision‑maker’s perspective and the practical experience of an adviser, enabling him to assist clients in antitrust proceedings, cross‑border disputes and complex matters of European litigation.

Impact for the firm

Mastroianni’s arrival enables GA‑Alliance to offer clients advice that integrates technical expertise, institutional experience and strategic capability in European litigation. This reinforcement is strategic in an increasingly complex regulatory environment, where understanding the dynamics of the single market and EU judicial procedures is crucial for legal risk management and for designing effective defensive and regulatory strategies.

Statement from the managing partner

Francesco Sciaudone, Managing Partner of GA‑Alliance, emphasised that Mastroianni’s appointment confirms the firm’s growth trajectory and its ability to attract leading legal and fiscal minds at both national and international levels. According to Sciaudone, the experience gained at the General Court of the European Union provides the firm’s clients with a depth of technical and institutional insight that constitutes a significant competitive advantage.

Conclusion and outlook

The appointment of Roberto Mastroianni as of counsel marks an important step for GA‑Alliance in building an integrated offering for high‑profile European litigation and antitrust matters. For clients operating in regulated and digital sectors, the presence of a figure with leading judicial and academic experience represents both reassurance and a strategic asset.
