PSPP Ruling (2020): ECB Bond Purchases and the German Constitutional Court’s Declaration that the Line Was Crossed

Can even the EU’s highest court be wrong? In 2020, Germany’s Federal Constitutional Court said yes.

The PSPP ruling gave me an immediate sense of, “This is a rather risky judgment.” It was surprising enough that Germany’s Federal Constitutional Court (BVerfG) challenged the European Central Bank (ECB)’s government-bond purchase program, but what was even more striking was that it effectively refused to accept the European Court of Justice (CJEU)’s assessment. If the Lisbon ruling was primarily a “warning,” the PSPP ruling is widely seen as having actually crossed the line. In this post, I will calmly整理 what the 2020 PSPP ruling was about, why it came to be described as an “unprecedented constitutional clash,” and what shockwaves it left in the European legal order.

What is PSPP: The ECB’s government-bond purchase program

PSPP (Public Sector Purchase Programme) is a large-scale government-bond purchase program introduced by the European Central Bank (ECB) in 2015. To respond to the euro area’s deflation risk and prolonged stagnation, the ECB aimed to expand the money supply and lower interest rates by purchasing large amounts of Member States’ government bonds on the market. Put simply, it was an unconventional monetary-policy strategy: “inject liquidity to revive the economy.”

The problem was the program’s scale and impact. As bond purchases continued over an extended period, questions arose as to whether this was no longer merely a tool for price stability, but instead directly affecting Member States’ public finances. In Germany in particular, constitutional complaints were filed amid criticism that “the ECB is effectively supporting national budgets.”

Issue: Monetary policy or economic policy?

The central issue in the PSPP case was whether the program fell within the scope of monetary policy granted to the ECB under the EU Treaties, or whether it intruded into the domain of economic and fiscal policy, which remains within Member State sovereignty. Monetary policy is an exclusive EU competence, while economic policy is, in principle, a Member State matter.

The Federal Constitutional Court considered this distinction not a mere formal categorization, but a question of who bears democratic responsibility and control. If classified as monetary policy, it falls under the ECB’s independence; if treated as economic policy, it is an area for which the German Bundestag must be accountable.

A head-on collision between the CJEU and the BVerfG

The case was first referred to the European Court of Justice (CJEU) for a preliminary ruling. The CJEU held that PSPP focused on the objective of price stability and that multiple safeguards were in place, and therefore qualified as a lawful monetary-policy measure. It also considered the proportionality review to be satisfied.

However, the Federal Constitutional Court did not agree. It criticized the CJEU’s proportionality analysis as excessively formalistic and argued that it lacked a substantive assessment of the program’s economic effects and side effects. At this point, the perspectives of the two courts diverged head-on.

Ultra vires review (Ultra-vires Kontrolle)

In its PSPP ruling, the BVerfG actively applied ultra vires review from the perspective of the German Basic Law. In other words, it asserted that it can examine whether EU institutions acted beyond the competences conferred by the Treaties—and this implies that Germany’s Constitutional Court can, in limited circumstances, intervene even with respect to EU-court judgments.

The Court concluded that PSPP went beyond the bounds protected as monetary policy and had effects akin to economic policy by materially supporting Member States’ public finances. Therefore, within the ultra vires framework, it pointed to the risk of an abuse of competence and declared that the ECB’s decision could conflict with the German Basic Law.

Aftermath and institutional responses

After the PSPP ruling, the German government and parliament strengthened monitoring of EU monetary policy and proportionality evaluation. The Court clarified the basis on which it can assess whether ECB measures are ultra vires, thereby leaving a precedent that Member States’ constitutional institutions may retain a certain degree of control over the exercise of EU powers.

Area	Response after the ruling
Exercise of ECB powers	Stronger proportionality and legality review by German constitutional organs
Effects of the bond-purchase program	Enhanced monitoring of impacts on national public finances
EU–Germany relationship	Clarification of the Constitutional Court’s authority to review EU law measures

The constitutional significance of the PSPP ruling

The PSPP ruling is a case showing that the German Constitutional Court can, in limited circumstances, refuse to follow the EU court’s assessment. It also clarified the boundary between monetary policy and economic policy and articulated a standard that democratic control and the proportionality principle must be meaningfully observed in practice.

• The German Federal Constitutional Court can apply ultra vires review to the exercise of EU-institution competences
• Review whether the ECB’s PSPP exceeds the scope of ordinary monetary policy
• Even as EU competences expand, the principles of democratic control and proportionality must be firmly secured
• The BVerfG’s stance serves as a significant precedent for future EU–Member State relations

Frequently Asked Questions about the PSPP Ruling

Does the PSPP ruling block all ECB policies?

No. The Court reviewed whether a specific program exceeded treaty limits; it did not deny the ECB’s general monetary-policy competence itself.

Doesn’t it conflict with the CJEU judgment?

Yes. The Federal Constitutional Court did not accept the CJEU’s assessment in a purely formal way and re-examined the practical effects and the scope of competence from the perspective of the German Basic Law.

What is ultra vires review?

It is a review of whether EU institutions exceeded the powers conferred by the Treaties, and it provides a basis for the BVerfG to intervene in limited circumstances even with respect to EU-court judgments.

What does this ruling mean for the German Parliament’s powers?

It implies that, when EU powers expand, the Bundestag’s duty of meaningful oversight and proportionality review is strengthened.

What impact did this ruling have on EU–Germany relations?

By showing that Germany’s Constitutional Court can intervene in limited circumstances with respect to EU-court judgments, it became an important precedent in debates over competence allocation between the EU and Member States.

How should I describe the PSPP ruling in an exam or report?

Structuring it in the following flow tends to be effective: monetary policy vs economic policy → ultra vires review → stronger parliamentary oversight → emphasis on democratic control and proportionality.

The Constitutional Message Left by the PSPP Ruling

The PSPP ruling goes beyond the question of the ECB program’s legality and stands as a major decision showing that the German Constitutional Court can retain substantive review authority over the exercise of EU-institution powers. It clarified the boundary between monetary policy and economic policy, and it delivered the message that democratic control and the proportionality principle must be secured in practice.

At the same time, by revealing the possibility of a competence clash between the EU’s highest court and the German Constitutional Court, it provided a precedent for Member State constitutional institutions to intervene in limited circumstances where EU powers are exercised beyond their limits. It has become a key reference point for understanding future EU–Member State relations, central-bank policy, and structures of democratic accountability.

Ultimately, the PSPP ruling asks how to balance “efficiency and integration” against “democratic control and constitutional compliance.” How that balance is maintained will shape the long-term stability of both the European legal order and the German Basic Law.

Lisbon Ruling (2009): The Limits of European Integration and the Final Line of the German Constitution

The European Union can grow stronger, but democratic legitimacy does not automatically follow.

The Lisbon ruling is one of those German Federal Constitutional Court decisions that creates an unusual sense of tension the more you read it. While supporting European integration in principle, it also draws a clear line and says, “This is the limit.” When I first encountered the decision, the first question that came to mind was, “Is it pro-European or anti-European?” But as I read on, I came to think that framing itself was misguided. This ruling was less about judging the EU and more about showing how a national constitutional court insists on protecting democratic self-determination and constitutional identity to the very end. In this post, I will walk step by step through what the Federal Constitutional Court allowed and what it said must not be crossed in the constitutional review concerning the Lisbon Treaty in 2009.

Background of the Lisbon Treaty and the issues raised

The Lisbon Treaty was concluded so that the European Union could move beyond being merely an economic community and develop a more integrated political and legal order. After the earlier European Constitutional Treaty was derailed by referendums, its core content was reconfigured in the form of an international treaty—the Lisbon Treaty. It granted the EU a single legal personality, expanded the powers of the European Parliament, and widened areas governed by qualified majority voting, thereby significantly deepening integration.

In Germany, the treaty was raised as a constitutional issue because it was not simply a diplomatic agreement but involved an additional transfer of state powers. The central concern was whether areas decided at the EU level would expand excessively without the democratic oversight of the Federal Parliament.

Issue: How far can sovereignty be transferred?

The core issue in this case was how far Germany can transfer national sovereignty to the EU within the limits permitted by the German Basic Law. The Basic Law is open to European integration, but it does not allow unlimited transfers of sovereignty. The question was whether the Lisbon Treaty crossed that line.

The Federal Constitutional Court approached the question not simply by asking “Did EU powers increase?” but from the perspective of whether German citizens still retain real room to make political decisions for themselves. In other words, it viewed the constitutional limit on transferring sovereignty as depending on whether democratic self-determination remains intact.

The democratic principle and the people’s right of self-determination

At the center of the Lisbon ruling is the democratic principle. The Court understood democracy not as a mere electoral procedure, but as a condition in which the people remain the subject of political rule. The key institution in this respect remains the parliaments of the Member States, and EU-level democratic legitimacy cannot fully replace them.

Accordingly, even if EU competences expand, in core areas directly tied to a state’s identity—such as criminal law, the military, fiscal matters, and social policy—the substantive decision-making power of the people’s representative institutions must be preserved. This is the minimum core of democratic self-determination in the Lisbon ruling.

Constitutional identity review (Identitätskontrolle)

The concept the Federal Constitutional Court most forcefully articulated in the Lisbon ruling is constitutional identity review. The Court declared that the core areas of the constitution protected by Article 79(3) of the Basic Law (the eternity clause) can never be infringed—even in the name of European integration. This means that, irrespective of the primacy of EU law, there exists a final boundary that the German constitution itself will safeguard.

This constitutional identity includes human dignity, the democratic principle, the rule-of-law principle, and the social-state principle. In particular, by placing democracy at the center, the Lisbon ruling made clear that a transfer of powers that hollowed out the people’s political right of self-determination cannot be constitutionally permitted.

The role of the Federal Parliament and its duty of oversight

The Lisbon ruling did not only assess the treaty’s constitutionality. The Court emphasized that the Bundestag (Federal Parliament) and the Bundesrat (Federal Council) have a constitutional duty to function as substantive oversight bodies in the process of European integration.

In particular, where EU competences could expand through mechanisms such as flexibility clauses or bridge clauses, the Court held that this cannot be left to governmental discretion alone; it must be accompanied by parliamentary oversight before and after the fact. As a result, Germany subsequently enacted legislation strengthening parliamentary involvement in EU matters.

Issue	What the Lisbon ruling requires
Expansion of EU competences	Explicit involvement of the Federal Parliament is necessary
Flexibility clauses and bridge clauses	The government cannot decide unilaterally
EU policy decision-making	Parliamentary information and oversight rights must be secured

The Lisbon ruling’s relevance today

The Lisbon ruling became the starting point for all subsequent German constitutional case law related to European integration. The reasoning repeatedly seen in decisions such as the OMT ruling and the PSPP ruling—“democratic self-determination,” “constitutional identity,” and “parliamentary oversight”—was systematized in this decision.

Lisbon is not “a ruling against the EU,” but rather a ruling declaring that European integration can be justified only within the constitution.

Frequently Asked Questions about the Lisbon Ruling

Is the Lisbon ruling a decision opposing European integration?

No. The Federal Constitutional Court clearly affirmed European integration itself. However, it drew a line by holding that integration must presuppose democratic legitimacy, and that going beyond that limit cannot be constitutionally permitted.

Does it not conflict with the primacy of EU law?

While the Court recognized the primacy of EU law in principle, it held that it retains final review authority with respect to the constitutional-identity domain. This is not ordinary legal application, but a form of control as the constitution’s last bulwark.

When does constitutional identity review become an issue?

It becomes an issue when the exercise of EU powers encroaches on the core domains the Basic Law protects as non-transferable, such as human dignity and the democratic principle. It is not triggered by mere policy-level disagreements.

Did the powers of the German Parliament actually strengthen after the Lisbon ruling?

Yes. Rights to information, consent, and ex ante oversight procedures for EU matters were concretized by statute. In particular, parliamentary involvement became an essential element when applying flexibility clauses and bridge clauses.

Did this decision influence other Member States?

It has no direct binding force outside Germany, but debates on constitutional identity and democratic legitimacy have significantly influenced subsequent case law and scholarship in other countries.

How should I structure the Lisbon ruling in an exam answer?

The key is to present the logic flow in a structured way: openness to European integration → democratic self-determination → constitutional identity review → stronger parliamentary oversight.

The Question Posed by the Lisbon Ruling: Who Decides Amid Integration?

The Lisbon ruling was not a decision telling Europe to stop integrating. Rather, the Federal Constitutional Court insisted to the end that even if integration continues, the process must not hollow out democracy. The message was that as EU competences grow, the structure in which parliaments—representative institutions of the people—exercise real oversight and responsibility must be strengthened alongside it.

In particular, the concept of constitutional identity review clearly applied the brakes to the integration logic that “everything can be transferred.” It made explicit that the constitution’s core—such as human dignity and the people’s democratic right of self-determination—cannot be diluted for reasons of efficiency or international cooperation. In doing so, the Court positioned itself not outside the EU legal order, but alongside it, as the guardian of the constitution’s final line.

That is why the Lisbon ruling is assessed as not merely a treaty-review judgment, but a starting point for the European constitutional dialogue that continues today. The question of what is permitted and what is prohibited between integration and sovereignty, efficiency and democracy remains ongoing. To understand the Lisbon ruling is to understand what role a constitution should play within that tension.

Internationale Handelsgesellschaft (1970): EU Law Supremacy vs. Fundamental Rights

“EU law prevails even over Member States’ constitutions.” This provocative statement captures the essence of the Internationale Handelsgesellschaft judgment.

Hello, students of European law. Today we examine Internationale Handelsgesellschaft (1970). When I first encountered this case, I wondered: “Can EU law really stand above national constitutions?” A German company argued that a Community regulation violated Germany’s Basic Law (constitution). The case pushed the principle of EU law supremacy to its limits while simultaneously raising the question of fundamental rights protection. Let’s unpack what this judgment means.

Background and Facts Core Issue: EU Law vs National Constitutions The Court’s Decision and Reasoning Impact on the EU Legal Order Criticism and Scholarly Debate Contemporary Significance and Takeaways

Background and Facts

The German company Internationale Handelsgesellschaft challenged a security-deposit system linked to grain export licences. Under then EEC rules, exporters had to lodge a deposit that would be forfeited if licence conditions were breached. The company argued that such forfeiture violated the German Basic Law (Grundgesetz), specifically the fundamental rights to freedom to choose one’s occupation and protection of property. In other words, the constitution and Community law were in direct conflict.

Core Issue: EU Law vs National Constitutions

At the heart of the case: Can a Member State’s constitution prevail over EU law? Because Germany’s Basic Law robustly protects fundamental rights, the clash was seen not merely as statute vs statute, but as a confrontation between constitutional values and Community norms.

Side	Claim	Core Reasoning
Internationale Handelsgesellschaft	Constitutional primacy	The EEC measure violates fundamental rights in the German Basic Law and is therefore invalid.
EEC / CJEU	Primacy of EU law	Even national constitutions cannot stand above Community law.

The Court’s Decision and Reasoning

The Court of Justice unequivocally reaffirmed EU law’s supremacy. Member States, having voluntarily transferred sovereign powers, cannot place their constitutions above Community law. At the same time, the Court stressed that fundamental rights form part of the general principles of Community law and will be respected and protected within the EU legal order. Key points:

• EU law prevails even over national constitutions to ensure uniform and effective application.
• If constitutions took priority, EU law would fragment and the Community project would collapse.
• Nevertheless, fundamental rights are safeguarded within EU law as general principles.

Impact on the EU Legal Order

The judgment clarified the absolute primacy of EU law, extending it to conflicts with national constitutions. At the same time, it catalyzed the development of fundamental rights protection within EU law. This trajectory led to cases like Nold and eventually the Charter of Fundamental Rights. The case marks a pivotal moment in balancing the EU legal order with a coherent fundamental rights regime.

Criticism and Scholarly Debate

Reactions were mixed. The ruling ensured uniformity of the EU legal order, but critics warned that it could threaten the authority of national constitutions and their fundamental-rights guarantees. The debate can be framed as follows:

Viewpoint	Main Argument
Critical	EU primacy can erode constitutional guarantees of fundamental rights.
Supportive	Fundamental rights are protected at EU level through general principles, allowing conflicts to be reconciled.

Contemporary Significance and Takeaways

This case still occupies a central place in EU law scholarship because it first exposed the tension between EU law supremacy and fundamental rights protection. Its takeaways:

• Explicit confirmation that EU law’s primacy extends even over national constitutions.
• A turning point introducing fundamental-rights protection within the EU legal framework via general principles.
• The starting point for tensions and dialogue with national constitutional courts, later reflected in the Solange line of cases.

Frequently Asked Questions (FAQ)

Q What was the Internationale Handelsgesellschaft case about?

A German company claimed that the EEC deposit requirement infringed fundamental rights under the German Basic Law, forcing a head-on clash between the national constitution and EU law.

Q What was the core issue?

Whether a Member State’s constitution can take precedence over EU law, and how fundamental rights protection resolves such conflicts.

Q How did the CJEU rule?

EU law prevails even over national constitutions, while fundamental rights are protected as general principles of EU law.

Q Why is this case important?

It confirmed EU law’s primacy even in direct constitutional conflicts and articulated, for the first time, a fundamental-rights protection principle within EU law.

Q What happened with Germany’s Federal Constitutional Court afterwards?

Solange I conditioned deference to EU law on sufficient protection of fundamental rights at EU level, keeping the dialogue—and tension—alive.

Q Does the case still matter today?

Yes. It is a touchstone whenever we discuss the balance between EU law supremacy and fundamental-rights protection.

In Closing

Internationale Handelsgesellschaft (1970) always prompts me to ask: “How strong can EU law be?” The declaration of primacy over constitutions was startling, while the promise to safeguard rights within EU law sought a balance. Without this case, later developments—like the Solange jurisprudence or the EU Charter of Fundamental Rights—might not have emerged. What do you think? Can EU law’s primacy over national constitutions always be justified in practice? Share your views—we can cross-examine perspectives and dig deeper together. 🙂
