Confirmation of a Violation of Fundamental Rights by the Federal Constitutional Court in the Context of the So-called Diesel Cases
On November 6, 2025, the Federal Constitutional Court (Case No. 2 BvR 1760/22) made a significant decision to secure effective legal protection under Article 19(4) of the Basic Law. The occasion was a constitutional complaint by a plaintiff whose civil action for damages against a vehicle manufacturer in connection with the diesel emissions scandals had been dismissed as inadmissible, and whose appeal was also rejected as inadmissible by the Higher Regional Court (OLG).
This decision has far-reaching implications both for litigation in economically relevant disputes and for the constitutionally protected right of individuals to access the courts.
Facts and Procedural Background
Course of the Civil Proceedings
The proceedings were based on a damage claim by a car buyer who had purchased a diesel vehicle equipped with an illegal defeat device. After the claim was dismissed by the regional court, the plaintiff attempted to challenge the first-instance judgment on appeal. However, the OLG dismissed the appeal as inadmissible, reasoning that the appeal lacked the necessary engagement with the key reasons of the challenged judgment.
Constitutional Complaint
The complainant lodged a constitutional complaint against this. He particularly alleged a violation of the fundamental right to effective legal protection (Article 19(4) GG) and the right to a fair hearing (Article 103(1) GG). The central question was whether the requirements for the appeal justification were exaggerated in this case and thus whether the right to effective access to legal remedies was not adequately respected.
Legal Doctrinal Evaluation
Significance of Effective Legal Protection
The fundamental right to effective legal protection protects individuals against disproportionate restrictions on access to the courts. According to the consistent case law of the Federal Constitutional Court, this also includes the requirement that the legal admissibility criteria for legal remedies be interpreted in light of the claim to justice.
In the present case, the Federal Constitutional Court examined whether the OLG had denied access to the second instance in a manner violating the constitution. The crucial issue was whether the appeal justification actually met the substantive requirements or whether unreasonable hurdles had been imposed on the complainant.
Limits of Judicial Requirements for Justifications
The Federal Constitutional Court emphasized that even though appeal submissions must meet minimum requirements for substance and content engagement, these requirements must not be exaggerated in a way that renders the reviewability of first-instance decisions effectively null. Citizens must not be hampered in their access to the second instance by excessive formal requirements.
In the decided case, the appeal justification from the viewpoint of the Constitutional Court was sufficiently individualized and related to a specific objection to the first-instance judgment. The blanket dismissal by the OLG thus constituted a violation of effective legal protection.
Relevance for Economic Legal Disputes
Impact on Litigation Strategy
The decision underscores the constitutional necessity of restraint when rejecting the opening of legal remedies solely based on formal criteria. For business parties and investors engaged in complex multi-instance proceedings, this reinforces the central role of the burden of demonstration in appeal proceedings – without leading to a de facto exclusion of access to legal remedies.
Signaling Effect for Practice
With this decision, the Federal Constitutional Court not only strengthens the position of the plaintiff side in the ongoing diesel cases but also sends a signal to the lower courts to continue conducting admissibility reviews of legal remedies with strict regard for fundamental rights. This becomes especially significant in large-scale economic disputes and mass damage cases where formal hurdles are strategically used.
Classification in the Context of Ongoing Diesel Cases
Against the backdrop of the large number of still pending cases in the diesel complex, the decision is to be understood as a reminder not to effectively curtail the legal protection of plaintiffs through excessive requirements. The presumption of innocence and the continuous existence of similar proceedings demand a differentiated consideration, the results of which are also likely to influence the litigation landscape in other civil mass proceedings (Status: November 2025, Source: https://urteile.news/BVerfG_2-BvR-176022_Federal_Constitutional_Court_confirms_violation_of_the_fundamental_right_of_effective_legal_protection_in_a_diesel_case~N35541).
Conclusion and Outlook
The current decision of the Federal Constitutional Court confirms the essential importance of effective legal protection even in economic mass proceedings. Courts are required, in the interest of maintaining equilibrium between procedural economy and fundamental rights protection, not to disproportionately raise barriers to legal remedies.
