School of Law


Justin studied Law and European Studies at the University of Malta. After qualifying as an advocate in Malta, he pursued postgraduate studies at the University of Aberdeen. This was followed by a lectureship at the University of Dundee. He joined the School of Law as a lecturer in 2012.

His research and teaching focus principally on the law of the European Union and Private International Law. The work includes analyses of Strategic Lawsuits Against Public Participation (SLAPP), jurisdictional and choice of law rules in defamation cases, cross-border regulation of companies, and the recognition of same-sex relationships. The unifying theme in this body of work is an exploration of the allocation of decisional power as between individuals, States, and supranational regulators.

Justin is the author of a leading monograph on corporate mobility (The Governing Law of Companies in EU Law (Hart 2012). The book was described as ‘a remarkable analysis of the complex issues resulting from the intersection of private international law of companies and companies' freedom of establishment under the TFEU’ (Behrens (2013) CMLR 1870). Another review says: ‘The book, no doubt, will make an important contribution to the future development of corporate mobility in the European Union…it is highly recommended.’ (Schillig (2014) ELR 151).

Justin regularly acts as a consultant on legal reform relating to his research. He advised the European Parliament on a review of the Brussels IIa Regulation, and was a member of a steering committee advising the European Commission on the possible introduction of legislation concerning the cross-border mobility of companies. He has also advised the UN Office of the High Commissioner for Human Rights, a coalition of press freedom NGOs, the European Parliament and European Commission on the introduction of anti-SLAPP legislation.

His work on the recognition of same-sex relationships was cited with approval in AG Wathelet's Opinion in Case C-673/16 Coman.

Research Overview

Justin's research explores several themes in private international law and EU law. He is able to provide lead supervision across a range of topics relating to his research. His published work explores the balance between individual freedoms and the rights of EU Member States to govern their socio-economic affairs. Publications span several iterations of the problem, including in respect of European company law, defamation, online gambling, and the recognition of same-sex relationships.   

Current Research

Justin's current research explores several facets of the prevention of Strategic Lawsuits Against Public Participation (SLAPP) in the European Union. In particular, the work explores how private international law rules can be deployed to suppress freedom of expression. The research was prompted by the redaction and deletion of press reports in an EU member state following vexatious threats of libel suits in jurisdictions in which a legal defence may have been beyond the prospective defendants' means. Justin's academic contributions in this area are accompanied by extensive public engagement with a view to supporting efforts to instigate legal reform.
