Historically For the Federal Diet of 1815, the basic law (Bundesakte) established two different formations. In the Plenary, for the most important decisions, every state had at least one vote. The larger states Austria, Prussia, Bavaria, Saxony, Hannover and Württemberg had four votes each; eight lesser states two or three, and the remaining 25 had only one vote. The North German Confederation was a different entity from the German Confederation, but it can also be regarded as the brainchild of a long lasting reform debate within the German Confederation. The new Bundesrat even referred to the old diet in Article 6, when it redistributed the votes for each states. Prussia, originally with four votes, gained the votes of the states it had annexed in 1866, i.e. Hanover, Hesse-Kassel, Holstein, Nassau, and Frankfurt, totaling 17 votes. The total number of votes in 1867 was 43 votes. When the South German states joined in 1870/71, the revised federal constitutions allocated new votes for them. Bavaria had six votes, Württemberg four, Baden three, and (the whole of) Hesse-Darmstadt three. The total number went up to 58 votes, and in 1911, with three new votes for Alsace-Lorraine, to 61 votes. The Prussian votes remained 17. To put the Prussian votes in context: 80% of North Germans lived in Prussia, and after 1871, Prussia made up two thirds of the German population and territory. Prussia was always underrepresented in the Bundesrat.
Weimar Republic The Reichsrat, as a first, had no fixed numbers of votes for the member states. Instead, it introduced the principle that the number depended on the actual number of inhabitants. Originally, states had one vote for every 1 million inhabitants. In 1921, this was reduced to 700,000 inhabitants per vote. No state was allowed to have more than 40 percent of the votes. This was regarded as a
clausula antiborussica, counterbalancing the dominant position of Prussia, which still contained roughly two-thirds of the German population. Also, since 1921, half of the Prussian votes were not cast by the Prussian state government but by the administrations of the
Prussian provinces. For example, of the 63 votes in 1919, Prussia had 25 votes, Bavaria seven, and Saxony five. 12 states had only one vote each.
Today The composition of the Bundesrat is different from other similar legislative bodies representing states (such as the
Russian Federation Council or the
U.S. Senate). Bundesrat members are not elected—either by popular vote or by the state parliaments—but are delegated by the respective state government. They do not enjoy a free mandate (for example, most parliamentary privileges in the Bundesrat can be exercised only by a
Land, not an individual member) and serve only as long as they are representing their state, not for a fixed period of time. Members of the Bundesrat (suffix "MdBR") do however enjoy the same
immunity from prosecution that
Members of the German Bundestag have. In addition, Members of the Bundesrat have unlimited access to sessions of the
Bundestag (where they have their own benches to the left of the President of the Bundestag) and its committees and can address it at any time. The latter right was most famously used in 2002 by then-Hamburg Senator
Ronald Schill, who
gave an inflammatory speech that was widely denounced. Normally, a state delegation consists of the
Minister-President (called Governing Mayor in Berlin, President of the Senate in Bremen and First Mayor in Hamburg) and other cabinet ministers (called senators in Berlin, Bremen, and Hamburg). State cabinets may appoint as many delegates as the state has votes, and usually do, but may also send a single delegate to exercise all of the state's votes. All other ministers/senators are usually appointed as deputy delegates. In any case, the state has to cast its votes
en bloc, i.e., without vote splitting. If Members of the Bundesrat from the same state vote differently, the entire votes of the state are counted as abstention. A famous example of this was a very close vote in 2002 on a new immigration law by the
Schröder government, when Deputy Minister-President of Brandenburg
Jörg Schönbohm (CDU) cast a no vote and State Minister Alwin Ziel (SPD) cast a yes vote. As state elections are not coordinated across Germany and can occur at any time, the majority distributions in the Bundesrat can change after any such election. Even without a new state election, it is possible that the state parliament installs a new state government because a new state coalition has formed. The number of votes a state is allocated is based on a form of
degressive proportionality according to its population. This way, smaller states have more votes than a distribution proportional to the population would grant. The presence of the small
city-states of
Bremen,
Hamburg, and
Berlin prevents the Bundesrat from having the rural and conservative bias of other similar legislative bodies biased in favor of small states. The allocation of votes is regulated by the
German constitution (
Grundgesetz). All of a state's votes are cast
en bloc—either for, against, in abstention of a proposal. Each state is allocated at least three votes, and a maximum of six. States with more than • 2 million inhabitants have 4 votes, • 6 million inhabitants have 5 votes, • 7 million inhabitants have 6 votes. By convention, SPD-led
Länder are summarized as
A-Länder, while those with governments led by CDU or CSU are called
B-Länder. While
legislative terms of the Bundestag are numbered, with the
21st Bundestag taking office in 2025, the Bundesrat has none, being a permanent institution with membership changes
staggered state by state.
Meetings have been numbered in a single sequence since 1949: it had its 1,000th plenary meeting on 12 February 2021. == Voting ==
