European Union Institutions
European Commission (Comisión Europea)
Core Functions
Proposes new EU laws ➜ starting point of ordinary legislative procedure.
Executes & manages EU policies once adopted (e.g., agriculture, digital agenda, Green Deal).
Monitors/ensures member-state compliance with EU rules; can launch infringement procedures before the Court of Justice.
Composition
27 Commissioners ("College of Commissioners") — exactly one per member state.
Each commissioner heads a Directorate-General (policy portfolio such as Education, Economy, Environment, etc.).
Appointment Process
Phase 1: Every national government nominates one commissioner-designate.
Phase 2: The full team (President + Commissioners) is subjected to a single confirmation vote in the European Parliament.
Significance
Only body with formal right of initiative for legislation.
Guardian of the Treaties (Art. 17 TEU). Failure to monitor can undermine uniform application of EU law.
European Parliament (Parlamento Europeo)
Core Functions
Co-legislates with the Council of the EU (ordinary legislative procedure, codecision).
Adopts the entire EU budget together with the Council; can reject it.
Democratic oversight: questions Commissioners, approves Commission, can pass motions of censure.
Represents EU citizens directly.
Composition & Organisation
Total MEPs: 720 (after 2024 allocation).
MEPs do not sit by nationality but by pan-European political group (e.g., EPP, S&D, Greens/EFA).
Each MEP has exactly 1 vote independent of home state size.
Election Mechanics
Direct universal suffrage every 5 years (next: 2029).
Conducted as parallel national elections; citizens vote for national parties, which join EU-level groups post-election.
Seat Allocation Principle: "Proportionality Degressive"
Larger states have more MEPs in absolute terms, yet smaller states enjoy higher per-capita representation.
Minimum per country: 6 seats; maximum: currently 96 seats (Germany).
Key Takeaways
Together with Commission + Council of the EU, forms the legislative triangle.
Only directly elected supranational parliament with budgetary power over a multi-state polity.
Council of the European Union (Consejo de la UE / Council of Ministers)
Core Functions
Co-legislator with Parliament.
Coordinates economic & social policies of member states (Ecofin, EPSCO configurations, etc.).
Concludes international agreements on behalf of the EU.
Composition
27 national ministers, configuration changes depending on dossier (e.g., agriculture ministers for CAP).
Decision-Making
Uses Qualified Majority Voting (QMV) for most areas: need 55\% of states representing 65\% of population.
Unanimity still required for sensitive matters (taxation, foreign policy, accession).
Selection
Ministers are not elected for the EU level; they are members of their domestic governments.
European Council (Consejo Europeo)
Strategic Role
Sets the overall political direction and priorities (e.g., enlargement, crises, multi-annual financial framework).
Does not adopt day-to-day legislation.
Composition
Heads of State or Government from all 27 member states (+ Commission President + European Council President).
Selection
Leaders obtain membership through national elections; no direct EU ballot.
Illustrative Issues Tackled
Brexit negotiations trigger article 50 guidance.
Sanctions packages after geopolitical conflicts.
Court of Justice of the European Union (Tribunal de Justicia de la UE)
Functions
Ensures uniform interpretation and application of EU law across all member states.
Handles infringement proceedings, preliminary rulings, annulments, and appeals.
Composition
27 Judges (one per country) + 11 Advocates-General who deliver independent legal opinions.
Appointment
Judges and AGs are jointly appointed by national governments for renewable 6-year terms.
Impact Example
Landmark cases: Van Gend en Loos (direct effect) & Costa v. ENEL (supremacy of EU law).
European Central Bank (Banco Central Europeo – ECB)
Core Tasks
Maintains price stability ➜ inflation target around 2\%.
Sets key interest rates (main refinancing, deposit facility, marginal lending).
Conducts monetary policy for the euro area (currently 20 countries).
Governance Structure
Executive Board: 6 members (President, Vice-President, 4 others).
Governing Council: Executive Board + Presidents of national central banks of euro-area states.
Selection
Euro-area governments appoint experts in economics/finance for 8-year non-renewable mandates.
Practical Significance
Quantitative easing (APP, PEPP) during crises; affects loans, mortgages, investment.
European Court of Auditors (Tribunal de Cuentas Europeo – ECA)
Mandate
Audits EU revenues & expenditures; identifies errors, fraud, inefficiencies.
Publishes Annual Report → basis for Parliament’s discharge procedure of the annual budget.
Composition
27 Members, one from each state; work in chambers.
Appointment
Governments nominate; Council appoints after consulting Parliament, term 6 years (renewable).
Cross-Institutional Connections & System Logic
"Institutional Triangle" for legislation: Commission (proposes) + Parliament (citizens) + Council of the EU (governments).
Checks & Balances
Parliament votes Commission in/out; ECJ can annul acts; ECA audits spending.
Democratic Layers
Citizens ➜ Parliament; States ➜ Council; Experts ➜ Commission/ECB/ECJ/ECA – creating multi-level governance.
Ethical & Practical Implications
Representation vs. efficiency debate: degressive proportionality protects small states but skews equality of vote weight.
ECB independence raises accountability questions; however, shields policy from short-term politics.
ECJ supremacy sometimes clashes with national constitutional identity (seen in German FCC judgments).
Quick Memory Hooks
"3 Cs" propose/approve: Commission (ideas) → Council + Parliament (laws).
European Council = "Big Picture" summit of leaders.
Court of Justice = referee ensuring rules are followed.
ECB = guardian of the euro’s buying power.
ECA = financial watchdog preventing €-waste.
