Politische Strukturen und Prozesse in Deutschland: Verfassungsordnung, Institutionen, Föderalismus, Wahlen
This domain tests how the Grundgesetz structures power and how that order operates in daily politics: constitutional principles, the constitutional organs, federalism, the electoral system and party competition. Hesse tasks typically combine a source (a constitutional article, a manifesto extract, a seat diagram) with a structured evaluation, so precise concepts matter more than general praise of democracy.
Constitutional bedrock
- Art. 20(1) fixes five principles: democracy, Rechtsstaat, Sozialstaat, federalism and - via Art. 20(2) - popular sovereignty.
- Art. 79(3) (Ewigkeitsklausel) removes Art. 1 and the Art. 20 principles from even a two-thirds amendment.
- Art. 1(3) binds all three powers to the Grundrechte; proportionality and judicial review operationalise the Rechtsstaat.
- Art. 21 gives parties a constitutional function in forming political will and subjects them to democratic internal order and public accounting.
Institutions and interlocking
- The Bundestag elects the Chancellor (Art. 63) and can remove him or her only by a constructive vote of no confidence (Art. 67): absolute majority plus a named successor - a deliberate lesson from Weimar.
- Art. 65 allocates authority inside the government: Kanzlerprinzip, Ressortprinzip, Kabinettsprinzip.
- The Bundesrat is the Länder chamber: absolute veto on Zustimmungsgesetze, merely suspensive Einspruch otherwise.
- The Bundesverfassungsgericht exercises concrete and abstract norm control and hears constitutional complaints.
Elections and parties
Personalised proportional representation combines a person-centred Erststimme with a party-centred Zweitstimme and a 5% threshold. The 2023 reform introduced Zweitstimmendeckung: the 630 seats follow second-vote shares only, and constituency winners are seated only if covered by that entitlement - overhang and compensation mandates are gone. Party competition shows dealignment, falling Volkspartei shares and a six-fraction Bundestag.
Worked example
A party takes 25% of second votes (about 157 of 630 seats) but wins 170 constituencies. Reasoning: the 5% hurdle is cleared, the entitlement is 157 seats, and Zweitstimmendeckung means only 157 constituency winners enter; 13 seats stay empty. The second vote, not the Erststimme, decides the total.
Traps
Mixing Erst- and Zweitstimme in seat sums; treating the Bundesrat as an equal second chamber; calling Art. 67 a simple-majority vote; claiming the Bundespräsident may refuse to sign a law for political reasons (Art. 82 permits only formal review).
