Essex Law School made a significant contribution to the ICON•S conference in Madrid in July 2024, with a substantial contingent of faculty and scholars in attendance. ICON•S is an international learned society with a worldwide membership of scholars – at all levels of seniority – working on different areas of public law and cognate disciplines in the humanities and social sciences. The Society was officially launched at its Inaugural Conference in Florence in June 2014, sponsored by the European University Institute and New York University School of Law. Since then, the Society has held annual meetings in New York (2015), Berlin (2016), Copenhagen (2017), Hong Kong (2018), Santiago de Chile (2019), online with ICON•S Mundo (2021), Wrocław (2022), and Wellington (2023). This year’s meeting (8-10 July), hosted by IE University in Madrid, attracted more than 2,000 delegates and was the largest meeting of the Society up to date.
The conference’s plenary programme was organised around the theme of The Future of Public Law: Resilience, Sustainability, and Artificial Intelligence. The theme, as explained in the conference’s Call for Papers, sought to “foster reflection and discussion on the different transformations that public law is going through as a result of the major societal challenges of our time: the quest for sustainability, the AI revolution and, more generally, the need for resilience in a world of exponential change.” Alongside the plenary programme, there were hundreds of parallel panels allowing scholars and the broader community (including practitioners, judges, and policy makers) to present their work and/or take part in thematically organised panels on legal pluralism, global warning, freedom of speech electoral law, democratic theory, human rights, judicial review, and many other areas.
The Essex Constitutional and Administrative Justice Initiative (CAJI) was in an excellent position to showcase the diversity of its interests and strengths both in terms of academic research and partnerships/collaboration across the world. CAJI Co-Director and Public Law Academic Lead, Professor Theodore Konstadinides noted how excellent the conference was to foster new collaborations and rejuvenate older relationships. For instance, he met with Professor Vanessa McDonnell (Associate Professor and Co-Director, uOttawa Public Law Centre) to discuss among else our respective partnership with Ottawa in public law and our newly-launched Canadian Constitutional Law module. He also reconnected with Giuseppe Martinico (Santa Anna in Pisa) in Madrid. Theodore also mentioned how the very stimulating environment of ICON•S kindled interests among our representatives to be more actively involved in the British Chapter of ICON•S in the future.
We have contributed to a number of different themes and panels this year, some specific to sustainability (Etienne Durand), some specific to digitalisation (Dr Giulia Gentile) and some more general (Professor Theodore Konstadinides, Dr Esin Küçuk, Dr Tom Flynn, Professor Yseult Marique). In a nutshell, here some of the main highlights of the conference for our team.

Professor Theodore Konstadinides chaired and participated in a panel entitled ‘Assessing the sub-constitutional space of the UK constituent nations in the post-Brexit constitution’. This panel discussed how within the EU multi-level order, governmental and legislative powers can be largely apportioned vertically at three tiers moving from regional to supranational: (i) substate-regional (e.g., Catalonia, Flanders, and Lombardy); (ii) (Member) State-national (e.g., Spain, Belgium, and Italy); and (iii) supranational, i.e., the European Union itself. The UK’s withdrawal from the EU apart from marking the first time that a Member State decided to put an abrupt end to the federalist ’sonderweg’ of ‘an ever closer union’, it meant that a number of powers that were exercised at the supranational level were ‘repatriated’. Four years after Brexit, this panel analysed the effect of such ‘repatriation’ on the sub-constitutional space of the UK constituent nations. It assessed whether this has happened at the expense of the devolved nations.
To do so, the three papers looked at the following areas of the UK’s post-Brexit territorial constitution: (i) foreign affairs (Professor Konstadinides, Essex and Professor Nikos Skoutaris, UEA); ii) the internal market (Ms Eleftheria Asimakopoulou, QMUL); and iii) digital governance (Dr Giulia Gentile, Essex). The picture that emerged from the papers highlighted the extent to which the UK constitutional order has proved its resilience – one of the themes of the 10th Annual conference.

For her third participation to an ICON•S conference (after Copenhagen in 2017 and online at the ICON Mundo during the pandemic), Professor Yseult Marique was invited to take part in a panel, part of a twin session on judicial deference following the reversal of Chevron by the US Supreme Court in Loper a few weeks earlier. This twin session was organised by Professor Oren Tamir (Arizona) and Professor Mariolina Eliantionio (Maastricht). This session was devoted to a comparison from European jurisdiction. Professor Marique’s co-presenters were colleagues drawn from past or present members of REALaw : Professor Luca de Lucia, Professor Luis Arroyo Jimenez, Professor Ferdinand Wollenschläger and Dr Pavlina Hubkova. The panel discussed whether their respective jurisdictions (Italy, Spain, Germany, Czech Republic and Belgium) have a similar concept or functional equivalent to deference.
The other session proceeded in a similar manner for Common law jurisdictions (USA – Professor Susan Rose Ackerman; South Africa – Professor Cora Hoexter; New Zealand – Professor Dean Knight; and Canada – represented by a long-standing collaborator of CAJI, Professor Matthew Lewans). A series of blog pieces on this topic is likely to be published on REALaw blog in the upcoming year.

Also very familiar with ICON•S, having presented in Wrocław in 2022 and in Wellington in 2023, Dr Tom Flynn was invited to take part in two sessions. One was a roundtable discussion of Radical Constitutional Pluralism in Europe (Routledge 2023) by Orlando Scarcello (KU Leuven). Dr Flynn had previously taken part in the book’s launch event on Zoom, and it was great to meet with Dr Scarcello and others in person to continue their discussion of the book. Dr Flynn’s presentation was entitled ‘Two Cheers for Substantive Pluralism’, and was a partial defence of the kind of substantive constitutional pluralism that Scarcello’s approach, with its specifically radical focus, discounts.
The other was a panel organised by Professor Mikel Díez Sarasola (Universidad del País Vasco/Euskal Herriko Unibertsitatea) on ‘Plurinational States and their Constitutional Shape’. Dr Ewan Smith (UCL) and Dr Flynn presented together on ‘The idea of parity of esteem as a constitutional principle in Northern Ireland and beyond’, which will be the focus of a BA-funded conference they are organising in Belfast in April 2025 with colleagues Prof Katy Hayward and Anurag Deb (both QUB).
After the panel, Professor Díez Sarasola was kind enough to organise a tour of the Congreso de los Diputades in Madrid, during which Tom was able to see the main chamber and the sala constitucional, among other parts of this magnificent building.

Also a former participant of the ICON Mundo conference, Dr Giulia Gentile was involved in three panels as a speaker. The panels concerned (a) AI and good administration, with a presentation covering AI and actions for damages; (b) the future of EU rights in the Brexit era, with a presentation discussing data protection in the UK post-Brexit landscape; (c) AI and courts, with a paper unpacking the interplay between judicial independence and the EU AI Act.
The panel on AI and actions for damages was a spin-off of a collaboration with Melanie Fink and Simona Demkova (both Leiden University) on AI and good administration. Her findings were published on DigiCon. The panel on EU rights after Brexit stems from collaboration and discussions with Essex colleague Theodore Konstadinides, with whom she is applying for a research funding bid on EU Citizens rights after Brexit. The final panel organised by Monika Zalnieriute offered Giulia the chance to discuss her forthcoming chapter on the AI Act and Judicial Independence to appear in the Cambridge Handbook on AI and Courts, edited by Dr Zalnieriute.

Dr Esin Küçük was involved in two panels, presenting papers. The first presentation, titled “Resilience of the EU Constitutional Order in Times of Crises”, was part of a panel on EU solidarity during crises. The debate centred on how recent measures to manage crises have reshaped our understanding of solidarity within the EU framework. This paper is now under review for publication.
The second paper Dr Küçük presented, “EU’s Externalised Smart Borders: Türkiye as a Case Study”, explores the externalisation of EU borders in migration management and the implications of emerging technologies in the process from a human rights perspective. This paper, co-authored with Elif Kuşkonmaz, is currently under development, and we aim to evolve this initial research into a broader project.

For his first participation to an ICON.S Conference, Dr Etienne Durand chaired the panel entitled ‘The Future of Energy Law: a Consumer-centric Legal Framework’, which featured Marie Beudels, (PhD Student in Law, University of Brussels, Belgium) and Dr Luka Martin Tomaszic (Assistant professeur, Alma Matar European University, Slovenia) as speakers.
The general aim of the discussions was to observe the changing nature of the role of energy consumers in their interaction with EU Law. The discussion was based on current developments in law and technology that enable energy consumers not only to benefit from the energy transition, but also to participate in bringing it about, thus playing an active role in (re)shaping the EU energy law itself. Taking these developments into consideration, the panel sought to identify the transformative power that energy consumers have or could have in shaping the future of European energy law, a hypothesis which we now aim to integrate into a broader research project.

Professor Joel Colón-Ríos first participated a panel titled “Navigating the Paradox: The Doctrine of Unconstitutional Constitutional Amendments”, where he commented on a paper by Sergio Verdugo (IE Madrid). His paper on the concept of a permanent constituent power was also presented in that panel by his co-author, Mariana Velasco Rivera (Maynooth). Later that day, Professor Colon-Rios chaired a roundtable titled “Deliberative Constitutionalism under Debate”, which featured papers by Cristina Lafont (Northwestern), Chiara Valentini (Bologna), Ana Cannilla (Glasgow), Roberto Gargarella (Pompeu Fabra, Torcuato di Tella), Yanina Welp (Albert Hirshman Democracy Centre), and Ignacio Guiffré (Pompeu Fabra).
On Tuesday, Professor Colon-Rios participated in a panel on “Constitutional Identity in Times of Illiberalism”, where some of the papers that will appear in an International Journal of Constitutional Law symposium where presented, including his piece (“Constitutional Identity, Democracy, and Illiberal Change”), co-authored with Svenja Behrendt (Max Planck, Freiburg). Finally, he was one of the speakers in the book roundtable of Guido Smorto’s and Sabrina Ragone’s Comparative Law: A Very Short Introduction. This was Professor Colon-Rios’ fifth ICON’s conference, also having co-organised last year’s annual meeting in Wellington.

Overall, the ICON•S provided a fascinating opportunity to learn from the Presidents and former President of the Human Rights Courts in Europe, Africa and South America; to meet up with old acquaintances and to catch up with the representatives of international publishing houses, always ready to provide feedback and chat about current and possible publishing projects. We were much bemused by how much Italians love Spain and very pleased to hear how lively the regional chapters were actively planning together for further activities (such as for instance the Benelux ICON•S Chapter.) The Essex Law team greatly enjoyed the event, and the team’s diverse work in public law contributes to excellent academic exchanges that we bring back to our undergraduate and postgraduate community as we are developing further our education curriculum and expanding our postgraduate research community in public law. We look forward to building stronger academic ties and impact at both in the UK and globally.
