Types of Constitutional Review Before the Federal Constitutional Court

The Federal Constitutional Court (Bundesverfassungsgericht) exercises several distinct types of constitutional review, each with its own procedural rules, standing requirements, and legal effects. The Grundgesetz and the Federal Constitutional Court Act (Bundesverfassungsgerichtsgesetz, BVerfGG) establish a comprehensive system of constitutional adjudication that includes abstract norm control, concrete norm control, constitutional complaints, Organstreit proceedings, federal-state disputes, and other specialised procedures. This diversity of procedural avenues ensures that constitutional questions can be brought before the Court by a wide range of actors and at various stages of the legislative and judicial process.

Abstract Norm Control (Abstrakte Normenkontrolle)

Abstract norm control (abstrakte Normenkontrolle) under Article 93(1)(2) GG and sections 13(6), 76–79 BVerfGG enables designated political actors to challenge the constitutionality of a federal or Land statute without waiting for a concrete case. The application must be filed by the Federal Government, a Land government, or one-quarter of the members of the Bundestag. The applicant must assert that the challenged statute is incompatible with the Grundgesetz, either substantively or procedurally. Abstract norm control is a subjective procedure in the sense that it is initiated by specific applicants, but it serves the objective purpose of ensuring constitutional uniformity. The Court may find the statute void, compatible with the constitution, or compatible only if interpreted in a particular manner (verfassungskonforme Auslegung). Abstract norm control has been used for politically significant legislation, including challenges to the Lisbon Treaty, the European Stability Mechanism, and the federal debt brake. The procedure enables constitutional review before a statute has been applied, preventing unconstitutional effects before they occur.

Concrete Norm Control (Konkrete Normenkontrolle)

Concrete norm control (konkrete Normenkontrolle) under Article 100(1) GG is the mechanism through which ordinary courts refer constitutional questions to the Federal Constitutional Court. When a court is convinced that a statute on which the decision depends is unconstitutional, it must stay the proceedings and refer the question to the Constitutional Court. If the court merely has doubts about the constitutionality, it may refer the question; if it is certain of the unconstitutionality, it must refer. The referral must specify the provision in question, the reasons for the court’s view that it is unconstitutional, and the relevance of the provision to the decision. The Federal Constitutional Court decides only the constitutional question; the referring court then applies the decision to the specific case. Concrete norm control ensures uniform constitutional interpretation across all court systems and prevents ordinary courts from applying unconstitutional statutes. The procedure accounts for a significant portion of the Federal Constitutional Court’s caseload and has generated much of the Court’s most important constitutional jurisprudence, including decisions on equality, proportionality, and fundamental rights.

Constitutional Complaint (Verfassungsbeschwerde)

The constitutional complaint (Verfassungsbeschwerde) under Article 93(1)(4a) GG and sections 13(8a), 90–95 BVerfGG is the most accessible avenue for constitutional review. Any person who claims that a public authority has violated their fundamental rights or rights equivalent to fundamental rights may file a constitutional complaint. The complaint may be directed against a statute, a judicial decision, an administrative act, or any other act of public authority. The complaint is subsidiary: the complainant must have exhausted all other legal remedies before filing. The Court may accept a complaint before exhaustion if the matter is of general constitutional significance or if requiring exhaustion would cause serious and irreparable harm. The Court does not review all complaints: a committee of three judges (Kammer) screens complaints and may reject those that are inadmissible or manifestly unfounded. If the complaint raises a constitutional question of fundamental importance, the Kammer may refer it to the Senate for decision. If the complaint succeeds, the Court declares the challenged act unconstitutional and, in the case of a judicial decision, quashes the decision and remands the case. The constitutional complaint has become the most commonly used procedure before the Federal Constitutional Court, with over five thousand complaints filed annually.

Organstreit Proceedings

Organstreit proceedings under Article 93(1)(1) GG and sections 13(5), 63–67 BVerfGG resolve disputes between constitutional organs or parts of organs about their rights and obligations under the Grundgesetz. Eligible applicants include the Federal President, the Bundestag, the Bundesrat, the Federal Government, and parliamentary groups or individual members of the Bundestag where their rights as members of a constitutional organ are affected. The dispute must concern a specific measure or omission that allegedly violates the applicant’s constitutional rights. Organstreit proceedings have been used to resolve disputes about legislative procedure, the rights of parliamentary committees, the scope of executive authority, and the relationship between the federal government and the Bundestag in European affairs. The Court’s decision in Organstreit proceedings declares whether the challenged measure violates the constitution but does not annul it. The proceeding is a subjective rights protection mechanism that enforces the rights of constitutional organs against each other, maintaining the balance of powers established by the Grundgesetz.

Federal-State Disputes

The Federal Constitutional Court adjudicates disputes between the Federation and the Länder (Bund-Länder-Streitigkeiten) under Article 93(1)(3) GG and sections 13(7), 68–70 BVerfGG. These proceedings resolve disagreements about the distribution of legislative and executive competences under the federal system. The Federation may challenge a Land law as exceeding the Land’s legislative competence, and a Land may challenge a federal law as exceeding the Federation’s competence. The Court also resolves disputes about the administration of federal laws by the Länder, the financial relations between the Federation and the Länder, and the implementation of European Union law. The federal-state dispute procedure ensures that the federal balance established by the Grundgesetz is maintained and that neither level of government encroaches on the competences of the other. The Court has decided landmark cases on federalism, including decisions on concurrent legislative powers, the financial equalisation system, and the limits of federal authority over Land administration.

Other Procedures

The Federal Constitutional Court also exercises jurisdiction over several specialised procedures. The party prohibition procedure (Parteiverbotsverfahren) under Article 21(2) GG enables the Court to declare a political party unconstitutional if it seeks to impair or abolish the free democratic basic order. The election review procedure (Wahlprüfungsverfahren) under Article 41(2) GG reviews challenges to the validity of Bundestag elections. The presidential impeachment procedure (Präsidentenanklage) under Article 61 GG enables the Bundestag or Bundesrat to impeach the Federal President for intentional violation of the Grundgesetz or a federal law. The judicial impeachment procedure (Richteranklage) under Article 98(2) GG allows the removal of federal judges who violate constitutional principles. The diversity of procedures reflects the framers’ commitment to comprehensive constitutional review and their confidence in the Federal Constitutional Court as the ultimate guardian of the Grundgesetz.
