Quantitative approaches are gaining popularity in German legal research. The analysis of large corpora of legal text may be supported by text mining methods. In this study, we employ topic modeling—which aims at retrieving the “topics” of a corpus—to identify words related to certain areas of law present in the case law of the German Federal Constitutional Court (FCC). This information is then evaluated by legal experts and used to show significant content-related differences between the two most frequent types of proceedings before the FCC. Technical and somewhat unstable areas of law, such as tax law, social law, and civil service law, are significantly overrepresented in referrals for judicial review, whereas areas of law characterized by well-developed case law and judicial doctrine appear substantially more often in constitutional complaints. This insight may come as a surprise due to the fact that the Court’s material scope of review is identical in both types of proceedings. Our considerations do not, however, seem to apply to private law. Though we recognize the methodological and epistemological concerns regarding the heuristic nature of topic modeling, this study exemplifies its productive use in complementing, rather than replacing, more traditional techniques of analysis in legal studies.

This Article introduces the German Law Journal’s Special Issue on “Solidarity in Diversity? State Responses to Religious Diversity in Liberal and Non-Liberal Perspectives”. The major countries in comparative focus are Germany and Singapore, both self-avowedly secular countries that face the challenge of religious diversity: Singapore, from inception, and Germany, through more recent developments. A key issue the Article raises concerns liberal approaches towards regulating religion; it argues that the liberal model, taking Germany as an example, may serve as a productive starting point for comparative analysis, as the liberal focus on individual religious freedom impacts managing religious diversity, shapes national cultural identity, models of secularism and social solidarity. This is compared with non-liberal approaches, as exemplified in Singapore practice, where a more communitarian outlook underpin more interventionist approaches whereby public interests and the common good tend to be prioritized over individual freedom. The comparative angles offered in this Special Issue is furthermore buttressed in several articles in this Special Issue that make comparisons to other jurisdictions-United States and Canada. This introductory Article offers a brief overview to the various contributions to this Special Issue and identifies unifying themes.

The law on state-church relations is no longer exclusively a national concern of the EU Member States. Despite supposedly strict neutrality clauses in the primary law of the EU and rigid statements—inter alia—by the German Federal Constitutional Court, it is safe to assume the formation of a supranational EU law on religion, which also touches upon the status of the churches and religious associations. This becomes obvious when state-church relations in Europe are reconstructed as a double conflict of laws that comprises interlocked conflicts between ecclesiastical law and worldly law, as well as between EU law and national law. Within the triangular relationship of these different legal spheres, EU law steers state-church relations towards the non-discrimination principle. The controversy in German law on religion between the proponents of a collective, institutionalist understanding (classic “Staatskirchenrecht”) and advocates of a rather fundamental rights-centered, individualist reading of the Constitution (“Religionsverfassungsrecht”) hence needs to be reconsidered. EU law calls for including yet a third paradigm into the debate: Equality.
