BundesverfassungsgerichtKarlsruhe · 1951–2024

Germany’s constitutional court cannot start a case. Handed eight, it banned a party, stopped a census and voided Berlin’s rent cap

Since it opened on 28 September 1951, the Bundesverfassungsgericht has concluded 266,588 proceedings. Someone had to bring every one: a government, a Land, a quarter of the Bundestag, a judge with doubts, or any citizen at all. In three of these eight landmark rulings it struck down a law. In the other five it decided who gets to decide.

01Who brings the cases

For every party-ban case, citizens have filed more than 25,000 complaints

Anyone who believes the state has violated their basic rights may go to Karlsruhe. Since September 1951, 258,712 constitutional complaints have arrived: 96% of all 268,777 proceedings. Bans on parties, the most drastic power the court holds, account for ten. Few complaints succeed: in 2024 the court decided 4,595 and upheld 39.

02Eight rulings, six players

Three of the eight struck down a law. The other five decided who gets to decide

Every ruling lands on someone. Read each one across: the court can strike an act down, let it stand under a condition that binds from then on, hand a player a power it did not have, or turn it away.

The only party ever banned that had sat in the Bundestag

On the federal government’s own application, Karlsruhe banned the KPD, the Communist Party, as anti-constitutional. It had won 5.7% and 15 seats in 1949 and had lost them by 1953. The government applied in November 1951 and waited four years and nine months. The ban set the precedent of a “streitbare Demokratie”, a democracy that defends itself.

A boycott call carried basic rights into private life

On 20 September 1950 Erich Lüth called for a boycott of Unsterbliche Geliebte, a new film by Veit Harlan, who had directed the antisemitic Nazi film “Jud Süß”. Lüth lost in the Hamburg civil courts. Seven years later Karlsruhe quashed their injunction: basic rights reach into private law too (“Drittwirkung”, their effect between private parties). Every German free-speech case since stands on it.

Bavaria sued over the treaty with East Germany, and had its answer in 64 days

The Bayerische Staatsregierung, Bavaria’s government, asked the court on 28 May 1973 to strike down Willy Brandt’s Basic Treaty with the GDR. Only a government, a Land or a quarter of the Bundestag may bring such a case. On 31 July, 64 days later, Bavaria lost. The treaty stood, but only as the court read it: a working arrangement, not formal recognition of the GDR, keeping a single German citizenship until 1990.

Six complaints stopped a national census

The court halted the count on 13 April 1983. On 15 December it struck down the data-sharing clauses of the census law (§ 9 Abs. 1–3), let the count go ahead only under new safeguards, and named a right written nowhere in the Grundgesetz: “informationelle Selbstbestimmung”, the right to decide what is known about you.

The complaint failed, but Karlsruhe kept a check on the European Union

The Maastricht Treaty was ratified. What survives is the court’s claim to review whether an act of the Union exceeds the powers Germany handed over, and its name for the Union: a “Staatenverbund”, a union of states. Karlsruhe had first reserved the right to test European law against German basic rights in 1974, and suspended that reservation in 1986.

The FDP sued the government it sat in, and parliament won a say over armed missions

The SPD and FDP groups in the Bundestag challenged the Adriatic embargo patrol, the AWACS flights over Bosnia and the logistics battalion sent to Somalia for UNOSOM II. Karlsruhe held deployments outside the NATO area lawful, but ruled that armed deployments abroad need the Bundestag’s consent: in advance, or straight afterwards in an emergency. It is why the Bundestag votes on armed missions abroad.

The treaty passed. The Bundestag’s own law did not

The Lisbon Treaty itself was compatible with the Grundgesetz. The accompanying law the Bundestag had passed was not: it gave parliament too little say over what Germany would agree to in the EU. Ratification waited for a better law, with the Bundesrat’s say strengthened too. Among those who brought the case were the Die Linke group in the Bundestag and the MP Peter Gauweiler.

284 MPs asked whether Berlin could cap its rents. The answer: void

Members of the Bundestag from the CDU/CSU and FDP filed on 6 May 2020, joined by two referrals from the Landgericht Berlin. On 25 March 2021 the court held the rent cap “mit dem Grundgesetz unvereinbar und deshalb nichtig”: incompatible with the Basic Law, and therefore void. Rent law belongs to the federal parliament. Landlords could claim the difference back to February 2020, when the law took effect.

Three laws fell. Everywhere else, the court redrew who may decide

The Bundestag was overruled two times and a Land one time. Across the eight rulings the court overruled a player five times, left ten standing only on its own conditions, and eleven times handed a player what it asked for or a power it had not had before. Citizens came out ahead in four.

03The census

Six complaints halted a national census for 246 days, and gave Germans a new right

Among the complainants were a law student, Gunther Frhr. von Mirbach, and two lawyers, Maja Stadler-Euler and Gisela Wild. On 13 April 1983 the court ordered the count stopped while it deliberated. On 15 December 1983 it struck down only the clauses that let census data be matched against registers and passed on, § 9 Abs. 1–3, and allowed the rest to go ahead under new procedural safeguards. The right it named, to decide for yourself what is known about you, is the German precursor to the EU’s data-protection law. Germany was counted in 1987 instead, under a law written to the court’s conditions.

04The court

No government can staff it alone: sixteen judges, each needing a two-thirds majority, for a single term

Two senates of 8; in each, half elected by the Bundestag, half by the Bundesrat

  • Judges16, 8 in each of two senates
  • Electedby the Bundestag and the Bundesrat, half each, by a two-thirds majority
  • Term12 years, no re-election; retire at 68
  • Quorum6 of 8 judges present
  • Robesscarlet, adopted in 1963
  • BuildingPaul Baumgarten, 1965–1969

A single term of 12 years, with no re-election and retirement at 68, means no judge is waiting on a government for a second term. The scarlet robes are younger than the court: adopted in 1963, cut by a costume designer at the Badisches Staatstheater in Karlsruhe after the judicial dress of fifteenth-century Florence. The court sits in Paul Baumgarten’s low glass-and-concrete pavilions of 1965–1969, beside the Karlsruhe palace.

05What falls

In ten years Karlsruhe found 147 provisions unconstitutional, and threw out only three whole laws

Between 2015 and 2024 the court found fault with 62 federal provisions and 85 in the laws of the Länder. Almost always it cuts out a clause, or part of one, and leaves the statute standing, as it did with the census law.

Two parties banned since 1951, and none since 1956

The court banned the SRP, a party in the tradition of the NSDAP, in 1952, and the KPD in 1956. In 2017 it refused to ban the NPD; in 2024 it cut its successor, Die Heimat, off from state funding instead.
