Debates over the role of religion in contemporary European constitutional orders have increasingly shifted from the national to the European level, placing EU law and the jurisprudence of the Court of Justice under sharper scrutiny. While concrete expressions of the freedom of religion largely remain within the ambit of the variable regulatory frameworks of the Member States, the EU Charter, the Treaties, and secondary law â predominantly concerning the prohibition of discrimination in the workplace â are substantially influencing and curtailing their scope of discretion. Accordingly, EU jurisprudence collides with and shapes questions of religion, concurrently generating resentment and contestation both among progressive liberal narratives demanding stronger equality rights and among more traditionalist movements expecting greater room for national margins and the role of religion therein.
Nonetheless, the EU is far from absent in this picture and plays an important role as an external corrective or supervisory actor. In our view, despite imperfections in the CJEUâs case law, the external and differentiated role of the Court and of EU law can challenge claims of self-referential sufficiency. EU law provides a mirror and necessitates a dialogue in which these convictions are tested and, where necessary, redefined. The fact that religionâs role in societies is a sensitive field, closely intertwined with tradition and historical developments in the Member States, does not shield these matters from this dialogue, but rather reinforces the need for it.
The contributions to the symposium In Good Faith seek to situate the role of the CJEU and its jurisprudence within this context. They either welcome the Courtâs generally deferential approach to the role of religion in the Member States or warn that the CJEU plays with fire in assuming that a single Luxembourg-approach can simultaneously deliver justice across Europeâs highly diverse and non-homogeneous legal and social landscapes.
The latest developments and the right balance
Beyond several general contributions on the changing role of the CJEU in matters of freedom of religion, this symposium analyses and elucidates some of the most recent and significant developments in this field. In particular, it examines, from highly diverse perspectives, Austriaâs latest prohibition on headscarves in schools for Muslim girls under the age of 14, scheduled to enter into force in September 2026. This legislation has been justified on the grounds that such a prohibition ostensibly promotes social integration and gender equality and prevents âfamilial or societal pressure [on Muslim girls] to wear certain clothing, which could have negative developmental and psychological effectsâ.
In addition, the symposium critically examines how the CJEUâs Egenberger judgment (C-414/16) decisively changed the relationship and oversight of the Member States and their religious communities. Specifically, it explores how the CJEUâs interpretation of the prohibition of discrimination in the workplace has prompted the German Federal Constitutional Court (FCC) to amend and progressively evolve its control and review of the constitutionally guaranteed right of churches to self-determination. Following the CJEUâs approach, the FCC changed its decades-long practice and determined that occupational requirements imposed by the Church on the employees must plausibly be linked to tasks and activities involved, thereby necessarily differentiating the categories of employment. In other words, a Church gardener does not necessarily need to belong to a particular religious denomination. Moreover, the courts must review these requirements to ensure they are proportional and thus subject to civil judicial scrutiny.
The FCCâs Egenberger decision of November 2025 shows how timely and relevant the questions of religious freedom in the EU are, particularly in light of the shared and constitutionally multilevel framework of several fundamental rights systems interacting in a complex equation.
Freedom of religion in the EU
Freedom of religion, one of the cornerstones of liberal constitutional democracies, cuts both ways. Conceived as a right of religious self-determination, it exerts a remarkable influence on liberal constitutional frameworks, successfully carving out space for its reservations. The Egenberger decision underscores the significant weight attached to the collective dimension of freedom of religion vis-Ă -vis the prohibition of discrimination. At the same time, freedom of religion is frequently curtailed under the pretext of neutrality, masking covert prejudice or paternalistic attempts to force individuals to be free. The recent Austrian example discussed above demonstrates this tension well.
Given the explicit neutrality carve-out under Article 17 TFEU, EU law finds itself between a rock and a hard place. While the Union protects against discrimination and directly legislates on equal treatment in employment, this inevitably challenges Member Statesâ prerogatives regarding the appropriate scope of freedom of religion, a particularly sensitive area.
The symposium In Good Faith revisits recent case law in an effort to reconcile the dual nature of religious freedom from an EU law perspective. It examines the reciprocal relationship between freedom of religion and other fundamental rights, exploring how the former may impose limitations on the latter and, conversely, how these rights can constrain freedom of religion.
Dual dynamics of freedom of religion â equality and liberty
Religious freedom, constitutionally protected in all EU Member States and enshrined in Article 10 of the EU Charter, remains deeply contested. The extent of this right and the relationship between state and religion differ across the Union. On the one hand, (formerly) dominant religions continue to enjoy privileges in many states â primarily based on their autonomy as religious communities, and often in tension with other rights. On the other hand, individual freedom of religion, in particular the wearing of religious symbols by Muslims, is readily restricted, selectively justified by appeals to neutrality, customer preference, or abstract notions of vivre ensemble. Conflicts around religious freedom are intensifying as right-wing and conservative movements increasingly invoke Europeâs Christian heritage, framing migration and Islam as perceived threats.
In its headscarf jurisprudence, the CJEU has adopted a restrained approach, granting Member States a wide margin of discretion. The CJEU interprets freedom of religion primarily in the context of equality, rather than as a liberty-right. As long as neutrality requirements apply to all employees, they are not deemed to disproportionately restrict religious freedom. This reasoning neglects the extent to which these restrictions interfere with the beliefs of the individual and disproportionately affect Muslim women.
With respect to religious employers, the CJEU has adopted stricter scrutiny, requiring national courts to assess whether occupational requirements are âgenuine, legitimate and justifiedâ, and ânecessary and objectively dictatedâ. This has narrowed the scope for denominational employers to discriminate, i.e. dismiss or hire persons, on grounds of belief. Nevertheless, religious communities continue to invoke their autonomy and right to self-determination to justify arguably discriminatory practices, as indicated by the latest Egenberger decision by the German FCC regarding church membership as a prerequisite for employment.
Like all fundamental rights, religious freedom must be carefully balanced against intersecting and competing rights and principles â equality, access to justice, state neutrality. Given the diverse understandings of religion across Member States, the CJEU has largely granted Member States discretion in religious matters while establishing only minimum standards. However, this judicial restraint rendered the Courtâs interpretation of religious freedom somewhat one-dimensional, overlooking its broader implications for equality, societal diversity, secularism, and the role of religion in secular democratic states. Such a narrow framework risks overlooking the complex interplay between religious rights and other fundamental principles of liberal democracies.
This symposium sheds light on the dual dynamics of religious freedom in Europe: both the restrictions imposed upon it and those justified in its name. It explores how religious freedom is invoked to undermine rights such as non-discrimination and reproductive autonomy, and how, conversely, individual religious freedom is curtailed by state or societal norms.
Between meaningful boundaries and disregard for pluralism
In cases concerning religion in the workplace, the CJEUâs generally assertive stance in anti-discrimination law aligns with its general deference to questions about religionâs role in society. Ronan McCrea analyses how the Court addresses this tension by setting wide but meaningful boundaries for Member States. Although this approach has been criticised in the past, McCrea explains why it constitutes a prudent and defensible choice in light of the existing legal framework and the evolving religious landscape in Europe.
By contrast, Andrea Pin argues that, in the name of anti-discrimination and neutrality, the CJEU risks undermining religious freedom in ways that are particularly detrimental to Muslim minorities â both by feeding into identity politics and by advancing a liberal narrative that frames restrictions as necessary to protect womenâs rights and non-discrimination. He is starkly critical of how the CJEU disregards the profound diversity of church-state relations and neglects the differing social positions occupied by religious communities across Member States. In his view, the CJEUâs approach is structurally ill-suited to the realities it seeks to address.
Headscarf jurisprudence and the contested balance
In its jurisprudence in the headscarf cases (Achbita, Bougnaoui, Wabe and MĂŒller, LF and OP), the CJEU has taken a largely deferential approach, emphasising neutrality as a legitimate aim, derived from the freedom to conduct a business for private entities and the principle of neutrality for public bodies. The CJEU thereby provided little protection for freedom of religion and overlooked broader implications for equality and societal diversity.
Accordingly, Erika Howard argues that the CJEU struck the wrong balance in the headscarf cases. The Court overemphasised neutrality while neglecting the implications of a de facto headscarf ban for individuals and society. Moreover, she criticises the Courtâs failure to engage with indirect discrimination based on grounds of sex or race (Article 21 of the EU Charter) or with the possibility of intersectional discrimination.
This narrow approach to indirect discrimination is also highlighted by Kristen Henrard. Her piece analyses how the Courtâs approach differs in its scrutiny. In cases of religious slaughter and headscarves at work, the Court has been largely deferential and arguably hides behind a broad margin of appreciation.
Prohibitions on wearing religious symbols affect minorities in particular. Maria Francesca Cavalcanti shows how the constitutional architecture of religious freedom and non-discrimination proves insufficient to capture the specific vulnerabilities and identity-based claims of minority communities. In her view, protecting minorities demands more than balancing rights. It requires recognising the specific forms of vulnerability produced by their social and constitutional position.
Forced to be free
Concerning the recently renewed prohibition of headscarves for Muslim pupils, proponents describe it as a âclear commitment to gender equalityâ and a step toward âempowering girlsâ. In 2020, however, the Austrian Constitutional Court had already declared a similar headscarve ban in schools unconstitutional. Peter BuĂjĂ€ger analyses how the new prohibition attempts to comply with the standards set by the Constitutional Court. Although the legislator has been largely successful in this regard, two crucial aspects seem to have been overlooked: the resulting stigmatisation and the underlying patriarchal structures. By contrast, Michael Lysander Fremuth supports this prohibition. Given the increasing number of reports from teachers and sociologists that girls lack autonomy and de facto freedom to determine their own identity, and considering the need to combat radicalisation and promote integration, he argues that these societal changes may prompt the Court to reassess and adapt its jurisprudence accordingly.
In addition, Paulus Blokker highlights the European struggle over the sacred and the profane. While not an entirely new phenomenon, the intensity seems to be increasing considerably. In his view, increasingly well-organised radical-conservative actors actively use liberal-democratic instruments to advance their claims in domestic and European political and legal arenas, a strategy amplified by an increasingly hostile international environment.
Egenberger and the limits of self-determination of churches
The symposium concludes with an analysis of the Egenberger decision by the German Federal Constitutional Court (FCC), a decision that was eagerly awaited. While the FCC avoided a looming conflict with the CJEU and affirmed a shared conception of fundamental rights, the decision offers numerous points for debate.
Lucy Vickers assesses the proportionality review employed in balancing the right to self-determination with individualsâ right to equality and non-discrimination. The fact that two courts could consider the same facts and reach opposite conclusions without either seeming to have misapplied the law shows how flexible the proportionality review can be. In her view, this flexibility is a great strength, allowing decisions of nuance and fact sensitivity, but also a significant weakness, demonstrating the fragility of the protection against discrimination on grounds of religion and belief in EU law.
Furthermore, Matthias Mahlmann analyses the decision and explains how the FCC changed its praxis, from now on requiring that occupational requirements imposed by the churches must have a direct link with the tasks in question. He argues that the FCC not only strengthens equality and non-discrimination but also reinforces the protection of religious freedom itself. In this light, the decision constitutes a substantial, constitutionally well-justified, fundamental-rights-friendly, and welcome shift.
In addition, Matthias Wendel and Sarah Geiger show that the Egenberger decision is not only about church labour law but also touches on fundamental issues in the interplay between national and European constitutional law in a multilevel system. While the FCC prevented unnecessary conflict with the CJEU through a balanced, conciliatory, and nuanced approach, they contend that the decision ends on an unwelcome note. By reasserting the possibility of national constitutional review of EU law with respect to individual fundamental rights under the Solange-doctrine, the FCC once again claims the authority to potentially disregard the primacy of EU law.
With numerous cases currently pending before the courts and a wide range of scholarly perspectives on the role of the CJEU in relation to freedom of religion and its associated rights, the issue remains more pertinent than ever. It appears that the questions addressed in this symposium are far from settled, and debates over the appropriate balance among these conflicting fundamental rights are likely to continue in the foreseeable future.
