# Cross-cutting context: European Union (supranational) law

Orchestrator cold-start for any plugin under `eu/`. Loaded before the plugin-specific `CLAUDE.md`.
Use `eu/` for **EU-wide supranational law** that applies across member states (GDPR, EU
regulations/directives, competition law, CJEU case law) — NOT for a single member state's
national law (that goes under its own ISO code: `de/`, `fr/`, …) and NOT for comparing
several countries (that is `cross-jurisdiction/`).

## Legal family

Sui generis supranational legal order. EU law has primacy over conflicting national law and,
for regulations, direct effect in all member states.

## Sources of law (by priority)

1. Primary law: the Treaties (TEU, TFEU) and the Charter of Fundamental Rights.
2. Secondary law: Regulations (directly applicable), Directives (transposed by member states),
   Decisions.
3. Case law of the Court of Justice of the European Union (Court of Justice + General Court).
4. General principles of EU law; international agreements concluded by the EU.

## Citation discipline (mandatory)

- Regulations/Directives: type, number, common name — e.g. "Regulation (EU) 2016/679 (GDPR),
  Art. 6"; "Directive 95/46/EC".
- Cases: "Case C-131/12, Google Spain, EU:C:2014:317".
- Cite the Official Journal (OJ) where relevant. **Never invent** instrument numbers, articles,
  or case numbers.
