How Does Germany’s Government System Work?

Germany’s government works as a federal parliamentary republic built on the 1949 Basic Law. A Chancellor chosen by parliament runs the executive; a two-chamber parliament made up of the directly elected Bundestag and the state-appointed Bundesrat makes federal law together; a Federal President serves as a mostly ceremonial head of state; and the Federal Constitutional Court in Karlsruhe has the last word on what the constitution allows. Power is split again between the federal level and 16 states, and the whole design is engineered to make concentrated authority almost impossible.

The Basic Law and What It Locks In

Germany’s constitution is the Basic Law (Grundgesetz). It opens by declaring human dignity inviolable, and Articles 1 through 19 set out directly enforceable fundamental rights: equality before the law, freedom of expression and the press, freedom of religion and conscience, peaceful assembly, privacy of correspondence, freedom of movement, protection of property, and asylum for those facing political persecution. These bind the legislature, the executive, and the judiciary as law, not as aspirations.¹

Three structural principles run through everything else. Germany is a federation: authority is split between Berlin and the 16 states (Länder), each with its own constitution, parliament, and government.² The federal government handles foreign policy, defense, immigration, and major economic regulation; the states run education, policing, and cultural affairs. Germany is a parliamentary democracy: the head of government depends on parliament’s confidence, not a direct popular vote. And Germany is a Rechtsstaat, a state governed by law, meaning every act of public authority needs a legal basis and can be challenged in court.

One clause sits above all the others. Article 79(3), the so-called eternity clause, says certain things can never be amended no matter how large the majority: the division into states, the states’ role in federal lawmaking, and the core principles of human dignity and democratic governance in Articles 1 and 20.¹ It was written in direct response to how the Weimar Constitution had been hollowed out from within.

The Chancellor and the Cabinet

The Federal Chancellor is the head of government and the most powerful figure in German politics. The Chancellor sets the general direction of government policy through what the Basic Law calls the guidelines competence (Richtlinienkompetenz).³ Ministers must work within those guidelines, but each one runs their own department on their own responsibility. That is ministerial autonomy, and it means the Chancellor cannot simply overrule a minister’s departmental decisions at will.⁴

How the Chancellor Is Elected

The Bundestag elects the Chancellor. The Federal President nominates a candidate — in practice, always the leader of the party or coalition that won the most recent election — and the Bundestag votes without debate. The candidate needs an absolute majority of all Bundestag members (currently 316 out of 630). If that fails, the Bundestag has 14 days to elect someone else by the same absolute majority. If that also fails, a final round is held in which the candidate with the most votes wins, and the President can either appoint the winner or dissolve the Bundestag and call new elections.³

Once elected, the Chancellor proposes ministers, and the President formally appoints them. The cabinet then governs as a collective body, with major decisions taken jointly.

The Constructive Vote of No Confidence

The Bundestag can remove a sitting Chancellor, but only in one specific way. A simple majority saying “we no longer trust this Chancellor” is not enough. The Bundestag must at the same time elect a replacement by an absolute majority of all its members. Only then does the President dismiss the outgoing Chancellor and appoint the new one, and at least 48 hours must pass between the motion and the vote.¹ This constructive vote of no confidence has been attempted twice. In 1972, Rainer Barzel tried to replace Willy Brandt and fell two votes short. In 1982, Helmut Kohl successfully replaced Helmut Schmidt after the FDP switched coalition partners. A Chancellor falls only if parliament already agrees on who comes next, which was the Weimar lesson the drafters had in mind.

The Federal President

The Federal President (Bundespräsident) is the head of state, and the role is largely ceremonial. The President represents Germany abroad, signs federal laws into effect, and formally appoints and dismisses the Chancellor and federal ministers, but these acts follow the outcomes of parliamentary votes rather than the President’s own choice.⁵ Nearly all official orders and directives of the President require a countersignature from the Chancellor or the relevant minister to take effect. The only exceptions are appointing or dismissing the Chancellor, dissolving the Bundestag under specific circumstances, and asking a caretaker Chancellor to stay on.¹ So real executive decisions always trace back to officials who answer to parliament.

The President serves a five-year term and is chosen not by voters but by the Federal Convention (Bundesversammlung), which meets only for this purpose. It combines all Bundestag members with an equal number of delegates picked by the state parliaments. A candidate needs an absolute majority in the first two rounds; if nobody clears that bar, a simple plurality wins in a third round.

Whether the President can refuse to sign a law is a long-running constitutional debate. The dominant view is that the President may decline only when the legislative process itself violated the constitution, not because the President dislikes the law’s substance. Presidents have occasionally withheld their signature, but it remains rare and controversial.

Parliament: Two Chambers, Two Roles

Germany’s parliament has two chambers. They serve different purposes, are composed in completely different ways, and hold different kinds of power.

The Bundestag

The Bundestag is the directly elected lower house and the center of legislative power. Its 630 members pass federal laws, elect the Chancellor, approve the federal budget, and oversee the government.⁶ Most detailed work happens in specialized committees that mirror government ministries and can demand reports from ministers and investigate on their own initiative. A quarter of Bundestag members can compel the creation of a formal committee of inquiry, which can question witnesses under oath, compel document production, and publish findings.⁷

The Bundesrat

The Bundesrat represents the 16 state governments at the federal level. Its members are not elected by voters. They are members of the state governments themselves, appointed and recalled by those governments.¹ Each state gets between three and six votes depending on population: every state has at least three, states above two million inhabitants get four, above six million get five, and above seven million get six. The Bundesrat has 69 votes in total, and each state must cast all of its votes as a bloc.⁸

How much the Bundesrat can do depends on the type of law. For legislation that directly affects state interests — state finances, administrative procedures, or state sovereignty — the Bundesrat’s consent is required, and it can block the bill outright. These consent laws make up close to half of all federal legislation.⁹ For everything else, the Bundesrat can lodge an objection, but the Bundestag can overrule that objection with a matching or larger majority.

How a Bill Becomes Federal Law

Bills can originate with the federal government, the Bundestag, or the Bundesrat. Most come from the government. A government bill goes first to the Bundesrat for an initial opinion, then to the Bundestag for committee deliberation and floor votes. If the Bundestag passes it, the bill returns to the Bundesrat.

When the two chambers disagree, either side or the federal government can convene the Mediation Committee, a joint body of 16 Bundestag members and 16 Bundesrat members, one from each state. If it reaches a compromise, the Bundestag votes on it in a special “fourth reading” with no floor debate, and the Bundesrat then takes a final vote.¹⁰ If mediation fails, a consent law dies; an objection law can proceed over the Bundesrat’s opposition. Once both chambers agree, the law goes to the Federal President for signature and publication in the Federal Law Gazette.

How Germans Elect the Bundestag

Germans elect the Bundestag through personalized proportional representation. Each voter casts two votes on the same ballot. The first vote (Erststimme) goes to a specific candidate in one of the 299 local constituencies. The second vote (Zweitstimme) goes to a political party, and it is the more important of the two: it determines each party’s overall share of the 630 Bundestag seats.¹¹

The 2023 Reform

A reform passed in 2023 and first used in the February 2025 election changed how seats are allocated. Under the old system, constituency winners always received a seat, and if a party won more constituencies than its second-vote share allowed, extra “overhang” seats were kept and other parties received “leveling” seats to restore proportionality. This inflated the Bundestag; the 2021 parliament had 736 members.

The new law fixes the Bundestag at 630 seats. Seats are allocated proportionally based on second votes from the outset. Constituency winners move to the top of their party’s state list and get priority for those seats, but winning a constituency no longer guarantees a seat. If a party wins more constituencies in a state than its proportional share allows, the lowest-performing constituency winners from that party miss out.¹¹ The 2025 election produced a Bundestag of exactly 630 members, the first time in decades the chamber did not exceed its target size.¹²

The Five Percent Threshold

To enter the Bundestag, a party normally needs at least five percent of all second votes nationwide. This threshold is meant to prevent the extreme fragmentation that made stable government almost impossible under Weimar. The 2023 reform originally eliminated the traditional fallback that let parties bypass the threshold if they won at least three constituencies. In July 2024 the Federal Constitutional Court ruled that elimination unconstitutional and ordered the three-constituency exception to remain in effect until parliament passes a corrected law.¹¹

Coalition Government and Opposition Rights

Because seats track second-vote shares closely, no single party has ever won an outright Bundestag majority in the history of the Federal Republic. Every federal government has been a coalition. After an election, the leading party negotiates a coalition agreement with one or more partners, dividing cabinet posts and setting a legislative agenda. Following the February 2025 election, the CDU/CSU and SPD formed a coalition government under Chancellor Friedrich Merz.

Coalition agreements are politically binding but not legally enforceable; no court will order a party to follow one. Their force is political: a partner that walks away can bring down the government, which gives smaller partners real leverage over policy.

Opposition power flows through minority rights rather than a formal opposition status. A quarter of Bundestag members can force an investigative committee, initiate abstract review of legislation before the Constitutional Court, or bring proceedings to enforce parliamentary rights.¹³ The Federal Constitutional Court has held that a general constitutional principle of effective opposition bars the majority from obstructing the opposition’s oversight work.

The Courts and the Federal Constitutional Court

Germany’s court system runs on five specialized branches, each with its own hierarchy from local courts to a federal apex court: ordinary courts for civil and criminal matters, and separate branches for administrative, labor, social, and fiscal cases.¹⁴ The lower and intermediate courts in each branch are run by the states; the top court in each branch is federal. Judges are career professionals who enter the judiciary through legal training, not political appointment.

Above and apart from all five branches sits the Federal Constitutional Court (Bundesverfassungsgericht) in Karlsruhe. It has the final word on what the Basic Law means and can strike down any federal or state law that violates the constitution, and its rulings bind every court, legislature, and agency in the country. It never acts on its own initiative. Cases reach it when the federal government, the Bundesrat, or a quarter of Bundestag members request abstract review of a law; when an ordinary court refers a case it believes turns on an unconstitutional law; or when constitutional organs bring disputes about their respective powers.¹⁵

Individual Constitutional Complaints

Cases also reach Karlsruhe through the individual constitutional complaint (Verfassungsbeschwerde). Any person, not just German citizens, can file a complaint claiming that a government action violated their fundamental rights. The complaint can target a court decision, an administrative act, or a statute itself.¹⁶

The requirements are strict. The complaint must be in writing, in German, and must identify the specific government action being challenged, the fundamental right claimed to be violated, and the details of how the violation occurred. Complainants must first exhaust all other legal remedies; appeals through the regular courts must be completed before turning to the Constitutional Court. The filing deadline is one month after the final lower court decision, or one year after a statute enters into force if the law itself is being challenged directly. The Court cannot extend these deadlines.¹⁶ Thousands are filed every year; only a small fraction are accepted for decision.

Germany and the European Union

Germany’s system does not operate in isolation. As a founding member of the European Union, Germany has transferred significant sovereign powers to EU institutions, and EU law shapes broad areas of policy from trade and agriculture to environmental regulation and consumer protection.

The Basic Law authorizes that transfer but sets conditions. Article 23 requires both the Bundestag and the Bundesrat to participate in EU affairs, and the federal government must inform both chambers about EU activities at the earliest possible date.¹ Any change to EU treaty foundations that would effectively amend the Basic Law needs the same two-thirds supermajority in both chambers that a constitutional amendment would need.

The Bundesrat plays an outsized role in EU matters. When proposed EU legislation primarily affects areas under state jurisdiction, its position becomes the decisive opinion, essentially giving the states the final word on Germany’s negotiating stance in Brussels. When EU legislation touches federal jurisdiction, the government must still give due consideration to the Bundesrat’s view, and a Bundesrat position backed by a two-thirds majority prevails if the two sides disagree. Where EU legislation falls mainly within exclusive state competence, a state minister nominated by the Bundesrat can lead the German delegation and cast Germany’s votes in the EU Council of Ministers.¹⁷

The relationship between the Federal Constitutional Court and the EU’s Court of Justice is one of the more consequential tensions in German constitutional law. The EU court holds that EU law is supreme over all national law, including national constitutions. The Federal Constitutional Court has never fully accepted that position. It treats EU law as supreme only because German law made it so, and it reserves the right to review EU actions that exceed the powers member states actually transferred or that threaten the core constitutional identity protected by the eternity clause. In practice, the two courts coexist through mutual restraint.
