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.
