As the Hungarian legislative elections approach, we are reminded of what is at stake for the whole of the European Union (EU). Since 2010, the Hungarian State’s democratic and Rule of Law standards have backslid, turning this Eastern European State in a de facto illiberal democracy,[1] dominated by Viktor Órban and his Fidesz party. Órban’s rule has been generally uncontested, even with European institutions increasingly drawing attention to Hungary’s severe democratic decline.[2] However, his grip on the Hungarian State has been facing rising challenges, such as several infringement procedures[3] and the activation of the Rule of Law conditionality mechanism.[4] The 2024 European Parliament elections gave challenger Péter Magyar the upward momentum to hinder Órban’s illiberal agenda and shake the foundations of his firm grasp on Hungary’s legal political system.[5]

The possibility of halting or reversing Hungary’s democratic decline is exponentiated by an infringement procedure pending before the Court of Justice of the European Union (CJEU). Case C- 769/22 Commission v. Hungary[6] is currently awaiting the CJEU’s ruling. However, when the Advocate General’s Opinion was published in June 2025,[7] we soon realised that the implications may go beyond the Hungarian case and help found what has been referred to as the justiciability of Article 2 of the Treaty on European Union (TEU). In summary, the legal argument is that the values enshrined in Article 2 TEU create concrete legal obligations for the Member States. If Member States fail to fulfil those obligations, their non-compliance can be used as grounds for launching infringement procedures, well within the ordinary competences of the CJEU. If the upcoming judgment eventually adopts the justiciability argument, we may be looking at a whole new phase of the constitutionality control carried out by the CJEU, keeping alive the aspiration of a society in which pluralism, non-discrimination, tolerance, justice, solidarity and equality between women and men prevail.

The deployment of xAI’s Grok chatbot has become a focal point of systemic risk within the European digital landscape. The European Commission first opened formal proceedings against X in December 2023.[1] In January of 2026, the scope of this regulatory oversight was significantly expanded under the Digital Services Act (DSA) to investigate Grok’s functionalities.[2] This investigation specifically targets risks such as the dissemination of non-consensual sexual deepfakes and antisemitic discourse. These controversies reveal a programmed tendency towards neutral language that masks structural biases within AI systems.[3]

This article explores how this systemic opacity creates an insurmountable barrier for individuals seeking legal redress against algorithmic discrimination. The core objective is to analyse the failure of the current reversal of the burden of proof mechanism, as provided by European anti-discrimination directives, when faced with high-dimensional mathematical optimisation. Ultimately, this text examines the necessity of technical solutions to harmonise automated processing with the values of justice and equality that underpin the European legal order.

As AI systems are developed and used by a wide range of individuals and organisations – not least military bodies, as recent events in Iran attest[2] –, it can become unclear who is responsible when something goes wrong. At its core, the debate surrounding responsibility for harm caused by a system (biological or otherwise) with a fractured or nonexistent legal personality is not unprecedented. Well before the age of algorithmic governance, legal and moral reasoning laid considerable groundwork for determining liability under circumstances wherein the link between intent and outcome is obscured by technical artefacts, chains of command, organisational setups, and status-based asymmetries.

In ancient Rome, for instance, legal issues around agency and liability were frequently addressed, prompting the legal order to evolve and respond with gradually emerging solutions. While not necessarily providing us with ready-made schemes, such precedents nonetheless draw our attention to the fact that legal issues involving responsibility have traditionally arisen and remedies were found as a result of incremental steps rather than by means of abrupt, one-off changes. This fact, the problems faced by our ancient peers, and the ways in which they managed them, offer valuable lessons and useful models when tackling today’s pressing AI regulatory challenges.[3]

1. Introduction

The protection of animal welfare has become an increasingly visible element of European Union (“EU”) action, particularly in policy areas traditionally dominated by economic considerations. The signing in January 2026 of the EU–Mercosur Free Trade Agreement (“EMTA”)[1] has made this a particularly salient issue for animal rights organisations and European citizens, serving as a contemporary example of how animal welfare is addressed both internally, and in the Union’s external action. Late in February 2026, President Ursula Von der Leyen announced that the Commission is moving forward with the provisional implementation of the agreement, although she stated that it can only be fully concluded after consent from the European Parliament.[2] This decision makes the subject of this article even more timely, as we shall examine the potential effects of such agreement on animal welfare matters across the EU.

That being said, whilst EU legislation has long addressed animal welfare in sectors such as agriculture, transport, and slaughter, the introduction of Article 13 Treaty on the Functioning of the European Union (“TFEU”) marked a significant symbolic development at the level of EU primary law, formally recognising animals as sentient beings.^[3] Despite this recognition, the legal status and practical relevance of Article 13 TFEU remain uncertain. The provision does not establish concrete obligations or enforceable rights but rather requires that animal welfare be taken into account in the definition and implementation of certain Union policies. This raises a fundamental question as to how animal welfare operates within the EU legal order when it comes into tension with other objectives pursued by the Union, particularly those linked to economic integration and trade.^[4]

A website launched just a few days before Valentine’s Day, with a Portuguese domain name entitled “Relationchip” garnered some attention in Portuguese social media for its innovative and controversial proposal to promote transparency in romantic relationships: i.e., through the use of two subcutaneous microchips and an app. As reported on the product’s website at the time of initial research for this post – providing information and a setup that differs from the one currently available –, “once implanted, the chips connect to the app and allow couples to access features such as real-time location tracking, password synchronisation and close contact alerts.”[1] Even though it raised suspicions that it might not be genuine, this product was being promoted on the website as being capable of reducing misunderstandings in relationships and strengthening intimacy with loved ones.

And, in fact, it was revealed that this device was fake, a fictitious product created by the Portuguese Association for Victim Support (APAV) to draw attention to controlling behaviour in romantic relationships, which is now part of young people’s daily lives through mobile phones and has become normalised: this is the information available on the website at the time of writing this article. For days, the fake product’s website was available, and criticism has already been levelled at the campaign’s content, given that it may have influenced or corroborated ideas about controlling one’s intimate partner through the use of new technologies, especially among young people.

Throughout 2025, the European Commission presented ten Omnibus packages with one central objective: to simplify European Union legislation, primarily by reducing the administrative costs and reporting obligations imposed on European companies, with a view to strengthening technological competitiveness.[1] This action favours faster procedures, less formalism and a reduction in regulatory fragmentation. However, the logic underlying this simplex, which is now presented as a “novelty”, has already been adopted in a different area, without much publicity, namely immigration and asylum policy. Here, the fluidity between criminal law and administrative law is a constant, with the legislator’s final option – in the name of simplification and speed – being to deal with all issues under the umbrella of administrative law. Observing this, experts analyse the phenomenon through the expression crimmigration.   

To understand this phenomenon, however, it is essential to revisit the evolution of the European immigration regime. The issue began to gain prominence in the 1980s, when the Schengen acquis led several Member States to abolish internal border controls, thus creating an area based on free movement and residence within European territory. And because this movement also included third-country nationals, it became clear that there was a need for coordinated external border control capable of responding to the expected increase in transnational crime.[2]
