How Government Works
Branches, separation of powers, federalism, and the checks that keep modern governments in balance.
Branches
Separation of powers
Montesquieu's 'The Spirit of the Laws' (1748) argued that power must be split across legislative, executive, and judicial functions or tyranny results. The American Founders absorbed this directly — James Madison's Federalist 47 quotes Montesquieu extensively in defending the new Constitution. Every modern democracy implements some version, with wide variation in how much each branch constrains the others. Pure separation (US-style) coexists with fused systems (Westminster parliamentarism) and hybrid arrangements (French semi-presidentialism). The functional question — not the formal one — is whether any single actor can change policy unilaterally without negotiation.
Key Points
- Madison in Federalist 51: 'Ambition must be made to counteract ambition' — institutional design must align officials' self-interest with constitutional restraint.
- Strict separation (US): each branch has distinct personnel and powers. Fused systems (Westminster): executive is drawn from legislature.
- Judicial review traces to Marbury v. Madison (1803, US), Marshall Court — established that courts may strike down statutes inconsistent with the Constitution.
- Constitutional review models: centralized (Kelsenian — one constitutional court, Germany/Italy/Spain) vs decentralized (US — all courts may decide constitutional questions).
- The 'unitary executive' theory (Calabresi, Yoo) reads Article II to give the US president plenary control over the executive branch — contested but increasingly influential post-2020.
- Strong-form vs weak-form judicial review (Tushnet 2008) — courts striking statutes vs declaring incompatibility for legislative response.
Legislative
Makes law. Unicameral (New Zealand, Denmark, Sweden, Israel) or bicameral (US, UK, Germany, India, Brazil, Mexico, Japan). Bicameral systems split into 'congruent' (similar parties dominate both chambers) and 'incongruent' (different majorities — German Bundesrat, US Senate vs House).
Executive
Implements and enforces law. Presidential (US, Brazil, Mexico, Indonesia, South Korea), parliamentary (UK, India, Germany, Japan, Australia, Canada), or semi-presidential (France, Russia, Taiwan, Portugal). Presidential executives have fixed terms and direct election; parliamentary executives depend on legislative confidence.
Judicial
Interprets law. Varies from supreme courts (US, India, Israel, Australia) to constitutional courts (Germany's Bundesverfassungsgericht, South Africa, South Korea, Italy) to no judicial review at all (Netherlands; UK before the Human Rights Act 1998 — Parliament remains supreme). Strong-form review (US, Germany) allows courts to strike down legislation; weak-form review (UK declarations of incompatibility) requires legislative response.
Presidential vs parliamentary
Juan Linz's 'The Perils of Presidentialism' (Journal of Democracy, 1990) argued presidential systems are more vulnerable to democratic breakdown because of dual legitimacy (president and legislature both claim popular mandate), fixed terms (cannot remove a failed leader through ordinary means), winner-take-all elections, and personalization of power. Empirical work since (Cheibub 2007, 'Presidentialism, Parliamentarism, and Democracy') has tempered the claim — institutional design matters more than the binary. But presidential breakdowns in Brazil (2016 impeachment), Peru (multiple presidents 2016-2022), and the US (Jan 6, 2021) keep the Linzian thesis alive.
Key Points
- Presidential: fixed terms, separate executive election, direct accountability. Risk: gridlock when branches conflict; impeachment as only removal tool.
- Parliamentary: PM chosen by legislature, can be removed via no-confidence vote at any time. Risk: coalition instability, frequent elections in fragmented systems (Italy, Israel).
- Semi-presidential: both PM and president exist with separate constitutional roles. France's cohabitation experience (1986-88, 1993-95, 1997-2002) illustrates hybrid strengths and weaknesses.
- Westminster fused systems (UK, Canada, Australia, India): executive sits in legislature; PM faces direct daily accountability (Prime Minister's Questions).
- Constructive vote of no confidence (German Basic Law Art 67): can only remove the chancellor by simultaneously electing a successor — prevents destructive instability.
- Term limits: US (2 terms via 22nd Amendment), Brazil (2 terms), Mexico (1 term, no reelection). Many parliamentary systems have no formal limit (Merkel served 16 years).
Federalism
Types of federalism
Federalism distributes sovereignty between a central government and constituent units (states, provinces, Länder, cantons). The classical distinction is between 'coming together' federalism (US 1787, Switzerland 1848, Australia 1901 — independent units pooling sovereignty) and 'holding together' federalism (Belgium 1993, Spain post-1978 — devolution to manage diversity within an existing state). Modern federalism's varieties — cooperative, dual, asymmetric, executive — describe different patterns of intergovernmental relations.
Cooperative federalism
National and subnational governments work together on overlapping responsibilities. Modern US Medicaid (federal funding, state administration), German Bund-Länder fiscal equalization (Finanzausgleich), Canadian healthcare (federal funding, provincial delivery). Dominant pattern post-1945.
Dual federalism
Strict division between national and state responsibilities — 'layer cake' federalism. 19th-century US (pre-New Deal), modern Switzerland's reserved cantonal powers, classical Australian federalism. Largely eclipsed by cooperative federalism but persists as constitutional doctrine in some areas.
Asymmetric federalism
Some subnational units have more autonomy than others. Spain's autonomous communities (Catalonia, Basque Country, Galicia have historical statutes), Canada's special status for Quebec (Charter of the French Language), India's J&K special status (Article 370, abrogated 2019), UK devolution (Scotland > Wales > Northern Ireland).
Executive federalism
Intergovernmental coordination happens through executive forums rather than constitutional rules — Canada's First Ministers Conferences, Germany's Ministerpräsidentenkonferenz, Australia's National Cabinet (post-2020).
Federal vs unitary: who does what?
The federal vs unitary distinction isn't binary — it's a spectrum from highly centralized unitary states (France pre-decentralization, Japan) through decentralized unitary states (UK post-devolution, Italy, Indonesia post-1999) to genuine federations (US, Germany, Canada, India, Brazil, Australia) to confederations where member states retain sovereignty (EU in significant respects).
Key Points
- Unitary (France, UK pre-devolution, Japan, South Korea): central government holds all sovereign power, delegates administratively.
- Federal (US, Germany, Canada, India, Australia, Brazil, Mexico): subnational units have constitutionally protected powers that the center cannot unilaterally alter.
- Confederal (EU in significant areas, historic US under Articles of Confederation 1781-89): voluntary union; member states retain ultimate sovereignty and exit rights.
- Decentralized unitary: UK post-1998 devolution to Scotland/Wales/Northern Ireland (asymmetric); Italy's 20 regions; Indonesia's post-1999 reformasi devolution.
- Fiscal federalism: vertical fiscal imbalance (units' spending responsibilities exceed their revenue) is universal; addressed through transfers, equalization, shared taxes.
- EU sui generis: stronger than confederation (binding law, court enforcement) but weaker than federation (no federal taxation, limited foreign policy unity).
Checks & Balances
Classic US checks
Madison in Federalist 51 argued 'ambition must be made to counteract ambition.' The US system is the textbook case — each branch has both shared and exclusive powers, with veto points scattered through the system. The design assumes adversarial competition between branches; when partisan alignment makes branches collaborate (unified government), the checks weaken. When divided government produces conflict, gridlock can result.
Key Points
- President can veto legislation; Congress can override with 2/3 supermajority in both chambers — rare in practice (around 7% of vetoes overridden in modern era).
- Senate confirms executive nominations (cabinet, judges) by majority vote and treaties by 2/3 supermajority; advice-and-consent (Constitution Art II §2).
- Supreme Court established judicial review in Marbury v. Madison (1803) — power to strike down statutes inconsistent with the Constitution.
- Impeachment: House indicts by majority (Constitution Art I §2), Senate tries with 2/3 conviction (Art I §3). Four presidents impeached (Andrew Johnson 1868, Clinton 1998, Trump 2019 and 2021), none convicted.
- Senate filibuster: cloture requires 60 votes — converts most legislation into supermajoritarian terrain; partial reforms in 2013 and 2017 removed filibuster for nominations.
- Power of the purse: Congress appropriates all federal spending (Art I §9 cl 7) — but executive impoundment fights and continuing resolution dynamics complicate this.
- War powers: Constitution gives Congress power to declare war (Art I §8 cl 11); War Powers Resolution (1973) attempts to constrain executive use of force.
Informal checks that matter more
Constitutional design only goes so far. Norms, media, and civil society do most of the day-to-day work of holding governments accountable. Levitsky and Ziblatt's 'How Democracies Die' (2018) argues that mutual toleration and institutional forbearance — unwritten norms — are democracy's deeper foundations. When formal checks remain but norms collapse, democracies erode without overt rupture.
Key Points
- Free press (Fourth Estate): investigation and accountability beyond courts. Press freedom (RSF, Freedom House) correlates strongly with democratic quality.
- Independent civil service and auditors: US GAO, UK NAO, India CAG, German Bundesrechnungshof — non-political watchdogs auditing government performance.
- Ombudsman offices: Scandinavia pioneered (Sweden 1809); now in 150+ countries. Investigate complaints, recommend remedies, lack binding power but shape public debate.
- Civil society + protest: last line of defense when institutions fail — South Korea's candlelight revolution (2016-17), Romania's anti-corruption protests, US Black Lives Matter movement.
- International monitoring: OSCE/ODIHR election observation, UN UPR, treaty body review — modest but cumulative pressure.
- Independent prosecutors and anti-corruption bodies (Italy's Mani Pulite, Brazil's Lava Jato, South Korea's special prosecutors) — when functioning, transform political accountability.
- Norms of forbearance: refusing to deploy formal power (court packing, mass impeachments, refusing to seat opposition) — invisible until violated.
Comparative Systems
United States vs United Kingdom
The two most influential English-speaking democracies have nearly opposite institutional designs. The US has a written constitution, presidential system, strong judicial review, federalism, and strict separation of powers. The UK has an uncodified constitution, parliamentary system, parliamentary sovereignty (qualified post-1998), unitary state (with asymmetric devolution), and fusion of executive and legislature. The contrast illuminates how different design choices produce different governance trade-offs.
Key Points
- Executive selection: US president directly elected via Electoral College; UK PM is leader of party commanding House of Commons majority.
- Term: US president fixed 4-year term (max 2); UK PM serves at confidence of Commons — Theresa May lost confidence 2019; Liz Truss resigned 49 days into office (2022).
- Legislative output: US Congress passes ~200-400 laws per Congress; UK Parliament passes 30-50 Acts per session with much higher pass rate for government bills.
- Judicial review: US Supreme Court can strike down statutes (Marbury 1803); UK Supreme Court (created 2009) cannot strike statutes but can declare incompatibility with HRA 1998.
- Federalism: US has 50 states with constitutionally protected powers; UK is unitary with devolved Scotland, Wales, Northern Ireland (asymmetric devolution since 1998).
- Constitution: US has 7,000-word written document (1787) with 27 amendments; UK has no codified constitution — Bagehot's 'efficient' vs 'dignified' parts, statutes, conventions, and case law.
Germany: rationalized parliamentarism
The Federal Republic's Basic Law (Grundgesetz, 1949) was designed to prevent Weimar Republic-style breakdown. Key innovations: constructive vote of no confidence (Article 67 — chancellor can only be removed by simultaneously electing successor), strong Federal Constitutional Court (Bundesverfassungsgericht), 5% threshold in mixed-member proportional system, federalism with strong Länder representation in the Bundesrat. The result is one of the most stable democratic systems globally — but with notable rigidity (coalition formation took 4-6 months in 2017 and 2021).
Key Points
- Constructive vote of no confidence (Art 67): chancellor only removable by Bundestag simultaneously electing successor — used successfully only once (Schmidt to Kohl, 1982).
- Bundesverfassungsgericht: strong constitutional review; can strike statutes, review treaties, and rule on competence disputes. Highly influential model globally (Israel, South Korea, South Africa).
- MMP electoral system (5% threshold) prevents fragmentation; produces stable coalitions but slow coalition formation (2017: 171 days; 2021: 73 days).
- Federalism: 16 Länder; Bundesrat (upper chamber of Länder governments) co-legislates on matters affecting states.
- Chancellor democracy: PM (chancellor) holds policy-direction power (Richtlinienkompetenz) but constrained by coalition agreements and cabinet ministers' autonomy.
- Militant democracy (streitbare Demokratie): parties hostile to free democratic basic order can be banned (KPD 1956, NPD attempt failed 2017) — distinctive German innovation.
India: world's largest federal parliamentary democracy
India's Constitution (1950) drew on the Government of India Act 1935, the US Constitution (fundamental rights), Westminster (parliamentary system), and Irish directive principles. The world's largest democracy by electorate (970M+ in 2024), with a quasi-federal structure that the Constitution describes as a 'Union of States' rather than a federation, reflecting strong centralizing features.
Key Points
- Westminster-style parliamentary system: PM and cabinet drawn from Lok Sabha (lower house) majority.
- Federal structure: 28 states + 8 union territories. State governments have substantial powers but Union can dissolve them under Article 356 (President's Rule — used 130+ times, declining post-Bommai 1994).
- Strong Supreme Court: 'basic structure' doctrine (Kesavananda Bharati 1973) limits constitutional amendment power — unique judicial innovation.
- Single transferable vote in elections for President and Rajya Sabha; FPTP for Lok Sabha and state legislatures.
- Reservation system: constitutionally mandated affirmative action for SCs, STs, OBCs across legislatures, education, public employment.
- Election Commission: constitutionally independent body conducts the world's largest elections — 2024 Lok Sabha election spanned 7 weeks with 642M votes cast.
FAQ
What makes a government democratic?
Dahl's 'Polyarchy' (1971) criteria: free and fair elections, universal suffrage, freedom of expression, alternative sources of information, associational autonomy, inclusive citizenship. V-Dem and Polity IV operationalize these. Modern measures distinguish electoral democracy (Dahl's procedural minimum), liberal democracy (adds rule of law and minority rights), participatory democracy, deliberative democracy, and egalitarian democracy — the V-Dem 'five high-level democracy indices.' Democratic backsliding indicators include erosion of judicial independence, media freedom, civil liberties — measurable before formal authoritarian rupture.
What are hybrid regimes?
Electoral authoritarianism — regimes that hold elections but don't meet democracy criteria. Russia, Turkey, Hungary, Venezuela in varying degrees. Levitsky and Way's 'competitive authoritarianism' (Journal of Democracy, 2002) is the canonical term: formal democratic institutions exist as the primary route to power, but incumbents use the state to tilt the playing field. Distinguished from hegemonic authoritarianism (elections are stage-managed) and full dictatorship (elections absent). V-Dem's 2024 Democracy Report finds 71% of world population live in autocracies, the highest figure in 20 years.
How does the UK system work without a written constitution?
The UK has an uncodified constitution — meaning it isn't contained in a single document, not that it doesn't exist. It comprises (1) statutes of constitutional significance (Magna Carta 1215, Bill of Rights 1689, Parliament Acts 1911/1949, European Communities Act 1972, Human Rights Act 1998, Constitutional Reform Act 2005, Fixed-term Parliaments Act 2011/repealed 2022), (2) common law principles (rule of law, parliamentary sovereignty), (3) constitutional conventions (royal assent always given, PM commands Commons majority, individual ministerial responsibility), and (4) authoritative works (Dicey, Bagehot, Erskine May). The lack of entrenched provisions means Parliament can in principle change any rule by ordinary majority — qualified by political and constitutional convention.
Why did Juan Linz think presidentialism was risky?
Linz (1990) identified four structural risks: (1) dual legitimacy — both president and legislature claim direct popular mandate, making conflicts intractable; (2) fixed terms — cannot remove a failed or extremist president through normal channels (impeachment is exceptional); (3) winner-take-all — losing presidential candidates have nothing; (4) personalization of power — outsiders can win without party gatekeeping. Cheibub (2007) responded that the apparent presidential-breakdown pattern reflects underlying economic and historical conditions (most Latin American presidencies coincided with military traditions), not the system itself. The Brazilian impeachment of Dilma Rousseff (2016), Peruvian instability (2016-2022), and US January 6, 2021 keep the debate live.
