The Bridge

The Legislative
Process

How an idea becomes EU law — from Commission proposal to Official Journal publication. Understanding this process is the single most tested topic in the AD5 exam.

The Institutional Triangle

⚙️

Proposes

European Commission

Sole right of legislative initiative. Drafts proposals and can withdraw them at any stage.

🏛️

Co-decides

European Parliament

720 MEPs directly elected. Amends and adopts legislation on equal footing with the Council.

🤝

Co-decides

Council of the EU

Ministers of member state governments. Adopts legislation by QMV in most cases.

The Trilogue Shortcut

In practice, over 85% of legislation is agreed through informal trilogues — direct negotiations between EP, Council, and Commission representatives — without going through all formal readings. This speeds up the process but reduces public transparency.

Ordinary Legislative Procedure

Step-by-Step

The OLP (formerly "co-decision") applies to the vast majority of EU legislation. Select a phase to explore.

European Commission

Commission Proposal

The Commission holds the monopoly on legislative initiative. It drafts and submits a legislative proposal (regulation, directive, or decision) to both the Parliament and the Council simultaneously. Proposals are developed with stakeholder consultation and impact assessments.

Possible outcomes

The Trilogue Shortcut

In practice, over 85% of OLP legislation is agreed informally via trilogues — direct negotiations between EP, Council, and Commission representatives — before the formal readings even conclude. This makes "1st reading adoption" the norm, not the exception.

Other Legislative Procedures

Consent Procedure

When Used

International agreements, EU enlargement, certain constitutional matters

How It Works

Parliament votes yes or no — cannot amend. Council must have Parliament's consent to proceed. Gives Parliament significant leverage despite having no amendment power.

Example

Trade agreements (e.g., CETA), EU accession treaties

Consultation Procedure

When Used

Taxation, competition rules, certain AFSJ matters

How It Works

Council must consult Parliament but is NOT bound by its opinion. Council adopts the act alone. The EP's opinion is advisory only.

Example

VAT rate changes, State aid rules

Special Legislative Procedure (SLP)

When Used

Varies by Treaty article — used for sensitive areas

How It Works

Either Parliament or Council acts alone, with the other merely consulted or giving consent. Defined case-by-case in the Treaty.

Example

Annual EU budget (Parliament consents), Own resources decision (Council acts, states ratify)

EU Legal Instruments

InstrumentBinding?Transposition?AddressesNotes

AD5 Exam Tip

What the Exam Tests

  • →Commission has the monopoly on legislative initiative — Parliament and Council can request but not propose.
  • →OLP = co-decision between Parliament and Council. Most EU legislation uses the OLP.
  • →A Regulation is directly applicable; a Directive requires national transposition.
  • →Trilogues are informal but dominate in practice — 85%+ of laws agreed at first reading.
  • →Conciliation is rare (third reading) — only triggered if both readings fail to reach agreement.
  • →Know when unanimity applies: taxation, CFSP, treaty revision, EU membership.
  • →The Commission can withdraw a proposal at any point during the procedure.
