Solange cases The Solange cases are two landmark judicial decisions that shaped the relationship between the Bundesverfassungsgericht and the European Court of Justice concerning the protection of fundamental rights within the European Economic Community and later the European Union. The rulings—commonly known as Solange I (1974) and Solange II (1986)—addressed whether and when a national constitutional court might review or limit the application of European Community law in light of national Grundrechte guarantees. These decisions influenced debates in Grundgesetz interpretation, EU law supremacy, and the development of the Charter of Fundamental Rights of the European Union.

Background and legal context

In the post‑war integration era, questions arose about the interaction between national constitutions such as the Grundgesetz and supranational instruments like the Treaty of Rome and later Single European Act. The Bundesverfassungsgericht had previously confronted tensions exemplified in cases involving European Court of Human Rights standards, NATO, and national sovereignty. The European Communities’ doctrine of the primacy of Community law—articulated by the European Court of Justice in cases such as Costa v ENEL and Van Gend en Loos—created a legal environment in which conflicts between the Grundgesetz and Community measures required judicial resolution. Actors such as the German Government, European Commission, national legislatures, and scholarly bodies like the Max Planck Institute for Comparative Public Law and International Law engaged these issues amid the broader context of Cold War politics and European integration.

Solange I (Re Wünsche Handelsgesellschaft)

In Solange I (1974), the Bundesverfassungsgericht addressed a preliminary ruling where the applicability of European Community law to a dispute involving Wünsche Handelsgesellschaft was central. The court asserted that as long as ("solange") the European Court of Justice did not ensure protection of fundamental rights to the extent afforded by the Grundgesetz, the Bundesverfassungsgericht reserved the right to review Community measures against the Basic Law. The judgment referenced standards developed by the European Convention on Human Rights, decisions of the Bundesverfassungsgericht itself, and comparative references to constitutional jurisprudence from courts such as the United States Supreme Court and the Cour de cassation. The ruling created significant tension with the European Court of Justice’s jurisprudence on absolute primacy and limited the automatic applicability of some Community norms within Germany.

Solange II (Re Handelsgesellschaft / Internationale Handelsgesellschaft follow-up)

In Solange II (1986), following developments in the European Court of Justice jurisprudence and the increasing protection of fundamental rights at the Community level, the Bundesverfassungsgericht modified its stance in cases arising from facts akin to Internationale Handelsgesellschaft. The court declared that it would no longer exercise the same restrictive review so long as ("solange") the European Community effectively protected basic rights in a manner essentially equivalent to the Grundgesetz. This shift acknowledged the ECJ’s role and cited decisions by the European Court of Human Rights, the European Parliament, and the European Commission initiatives, and it paved the way for greater mutual trust between national constitutional courts and EU institutions such as the Council of the European Union and the European Council.

Legal principles and doctrine established

The Solange rulings articulated a conditional doctrine balancing national constitutional identity and the primacy of Community law. Key principles include the conditional acceptance of EU legal supremacy, the protection of constitutional identity under the Grundgesetz, and the use of comparative human rights standards from the European Convention on Human Rights. The doctrine influenced concepts like constitutional tolerance, judicial comity between the Bundesverfassungsgericht and the European Court of Justice, and the evolution of fundamental rights protection culminating in instruments such as the Charter of Fundamental Rights of the European Union and protocols to the European Convention on Human Rights.

Subsequent case law and influence on EU constitutionalism

Solange I and II informed major decisions across jurisdictions, contributing to jurisprudence in cases like Fraenkel, Demirel, Costa v ENEL reinterpretations, and later Kadi. The dialogue between constitutional courts—such as the Constitutional Court of Italy, the Constitutional Court of Spain, and the Polish Constitutional Tribunal—and the European Court of Justice reflected the Solange legacy in debates over primacy of EU law and national identity clauses later enshrined in protocols to the Treaty of Lisbon. Scholarly work from institutions like the European University Institute and publications in journals associated with the Max Planck Society analyzed the Solange framework amid landmark developments including the adoption of the Charter of Fundamental Rights and accession debates involving the European Convention on Human Rights.

Criticism and scholarly debate

Scholars and jurists have critiqued the Solange approach from diverse perspectives, invoking authorities such as Hans Kelsen, Jürgen Habermas, Ernst Forsthoff, and proponents of constitutional pluralism like A. Smits and J. Weiler. Criticisms focus on legal certainty, democratic legitimacy, and potential fragmentation of EU law through national constitutional reservations. Debates in comparative law networks and forums including the European Consortium for Political Research and publications from the Hertie School examined whether Solange’s conditionalism fosters constructive dialogue or poses risks to uniform application of Community law. Alternative proposals from scholars at the London School of Economics, University of Cambridge, and University of Oxford evaluated mechanisms for stronger human rights guarantees at the EU level to reduce constitutional friction.
