Broken Promises? The Withdrawal Agreement and the Quiet Erosion of EU Citizens’ Rights in Britain
A Family Caught Between Law and Interpretation
In the years following Brexit, the United Kingdom repeatedly assured millions of European residents that their rights would remain protected. At the heart of that assurance was the EU–UK Withdrawal Agreement—a binding international treaty designed to guarantee continuity for EU citizens and their families lawfully residing in Britain.
Yet, for one Lithuanian family who had settled in the UK well before Brexit, that promise now appears fragile. Despite holding lawful residence documentation issued years earlier, they found themselves excluded from key protections—not because they lacked legal status, but because they had not registered under the EU Settlement Scheme (EUSS), a system introduced after the Withdrawal Agreement came into force.
Despite mounting concerns over the treatment of EU nationals in post-Brexit Britain, Ursula von der Leyen has yet to take any visibly decisive initiative to resolve the ongoing disputes affecting EU citizens and their family members in the United Kingdom. Critics argue that, while the European Commission has the legal and diplomatic instruments to intervene—particularly under the EU–UK Withdrawal Agreement—its response has been muted, leaving affected individuals to navigate complex legal challenges with limited institutional backing.
At the same time, the European Union continues to pursue deeper cooperation with the UK, including potential defence and trade agreements. This dual-track approach has drawn criticism, with some arguing it sends a contradictory signal: advancing strategic partnerships while allegations persist that EU citizens and their families are being treated as second- or even third-class residents in the UK. For those directly impacted, the gap between high-level diplomacy and lived reality remains stark and unresolved.
Continuity vs. Conditionality
The legal tension is stark. The Withdrawal Agreement explicitly guarantees that EU citizens and their family members can continue to live, work, and access services under broadly the same conditions as before Brexit. The principle is clear: continuity of rights.
However, UK courts have adopted a narrower interpretation. In several rulings, judges have concluded that while rights exist in principle, they are only enforceable if individuals have successfully applied to the EUSS. In effect, continuity has been made conditional.
This interpretation raises profound legal questions. Can an administrative requirement—particularly one introduced after the treaty—override the substantive protections guaranteed by an international agreement? And more critically, does failure to register nullify rights that were previously recognised and documented by the state itself?
The Administrative Gap
For the Lithuanian case, the issue is not merely legal—it is procedural. The individual in question had received an EU family permit as early as 2009, followed by extended residence documentation valid through 2024. These were not informal arrangements; they were official recognitions by the UK government of lawful residence.
Yet, after Brexit, those physical residence documents were effectively invalidated in practice. There was no direct communication—no formal letters, no targeted outreach—informing such individuals that failure to register under the EUSS could jeopardise their rights.
Even at points of entry, such as interactions with border authorities, there appears to have been limited proactive guidance. The transition from a document-based system to a fully digital immigration status left many—particularly vulnerable or less digitally engaged individuals—unaware of the administrative shift.
Healthcare and the Cost of Exclusion
The consequences of this gap have been severe. Access to public services, particularly healthcare through the National Health Service (NHS), has become contingent on EUSS registration.
In practice, this has led to situations where individuals—despite long-term lawful residence—are treated as ineligible for free care. Hospitals have issued invoices, arguing that without EUSS status, rights under the Withdrawal Agreement are not enforceable. For affected families, the message is blunt: register, or pay.
Critics argue that such enforcement mechanisms effectively weaponise administrative compliance, turning a bureaucratic requirement into a gatekeeper for fundamental rights.
The Role of Oversight Bodies
The controversy also places scrutiny on oversight institutions. The Independent Monitoring Authority for the Citizens’ Rights Agreements (IMA) was established precisely to ensure that the UK upholds its obligations under the Withdrawal Agreement.
Yet, campaigners and affected individuals question whether the IMA has acted robustly enough. With substantial public funding, expectations were high that it would intervene decisively in cases where rights appear to be undermined. So far, critics argue, its impact has been limited.
At the European level, leadership figures such as Ursula von der Leyen face growing pressure to ensure that EU citizens’ rights are not diluted through domestic reinterpretations.
Legal Interpretation or Legal Drift?
At the core of the issue lies a fundamental jurisprudential question: interpretation versus transformation.
UK courts maintain that the EUSS is a lawful mechanism to operationalise the Withdrawal Agreement. From this perspective, registration is not a denial of rights, but a procedural step necessary to evidence them.
However, critics argue that this reasoning risks creating a two-tier system—those who navigated the administrative process successfully, and those who did not, regardless of their underlying legal entitlement.
The concern is that “continuity,” as promised in the treaty, is being redefined through domestic legal interpretation into something closer to conditional eligibility.
A Precedent with Wider Implications
The Lithuanian case is unlikely to remain isolated. Across the UK, there are thousands of EU citizens and family members who may have fallen through similar administrative cracks—particularly elderly individuals, children, and those with limited access to legal advice.
If the current judicial approach holds, it sets a powerful precedent: that rights guaranteed under an international treaty can be effectively curtailed through procedural non-compliance.
Where Is Justice?
The broader question is one of legal integrity. Can a state guarantee rights in an international agreement, only to later condition their exercise on a domestic administrative scheme introduced after the fact?
For affected families, this is not an abstract legal debate. It is about access to healthcare, the right to work, and the security of knowing that their lives in the UK are not subject to sudden reinterpretation.
The promise of the Withdrawal Agreement was clarity and certainty. For many, that promise now feels uncertain.
The Lithuanian case exposes a fault line in the post-Brexit legal order—between the letter of international commitments and their domestic implementation.
Whether this represents a necessary administrative framework or a troubling erosion of rights remains contested. What is clear, however, is that the principle of continuity—once central to the Withdrawal Agreement—is now at the centre of a legal and moral debate that is far from settled.
