Cross-Reference Verification

EU law contains extensive cross-references. Always verify referenced texts to provide accurate answers.

Types of References

| Reference Type | Example | How to Verify |

|-------------------------------------|----------------------------------|------------------------------------------------------------------------------------|

| Internal article | "Article 21" | Re-read the full text |

| External act | "Regulation (EU) 2016/679" | GoodLegal API or EUR-Lex /TXT/ |

| Annex | "Annex I, Part B" | EUR-Lex /ALL/ page |

| Implementing act (Art. 291 TFEU) | "Commission Implementing Regulation" | EUR-Lex /ALL/ → "Internal procedures based on this legislative basic act" |

| Delegated act (Art. 290 TFEU) | "Commission Delegated Regulation" | EUR-Lex /ALL/ → "Internal procedures based on this legislative basic act" |

| CJEU case law | "Case C-xxx/xx" | EUR-Lex /ALL/ → "Affected by case" |

Verification Workflow

Reading EU text
    │
    ├─► Found "Article X" reference?
    │       └─► WebFetch same document, extract Article X
    │
    ├─► Found "Directive/Regulation XXXX/XXX" reference?
    │       └─► GoodLegal API with CELEX ID
    │           OR WebFetch EUR-Lex /TXT/ page
    │
    ├─► Found "Annex" reference?
    │       └─► WebFetch EUR-Lex /ALL/ page
    │           Look for "Annexes" section
    │
    └─► Need related/implementing acts?
            └─► WebFetch EUR-Lex /ALL/ page
                Look for:
                - "Implemented by"
                - "Delegated acts"
                - "Related documents"
                - "Based on"

Using /ALL/ for Related Documents

The /ALL/ page shows the complete document ecosystem:

https://eur-lex.europa.eu/legal-content/EN/ALL/?uri=CELEX:{CELEX}

What to look for:

| EUR-Lex Label | Contains |

|-----------------------------------------------------------|-------------------------------------------------------------------|

| Legal basis | Treaties (Art. 290, 291 TFEU), parent legislation |

| Internal procedures based on this legislative basic act | Implementing acts (Art. 291 TFEU) and Delegated acts (Art. 290 TFEU) |

| Modified by | Amending acts with dates and affected subdivisions |

| Modifies | Acts that this document amends |

| Corrected by | Corrigenda (language-specific corrections) |

| Subsequent related instruments | Follow-up legislation, related acts |

| Affected by case | CJEU judgments interpreting this act |

| Consolidated text | Link to consolidated version with all amendments |

Note: Implementing acts (uniform application conditions) and Delegated acts (supplement/amend non-essential elements) are often grouped together under "Internal procedures".

Example: Answering a Legal Question

User asks: "What are the penalties under Directive 20XX/XXX?"

Step 1: Get full text
        → GoodLegal API: "320XXLXXXX"

Step 2: Find sanctions article (e.g., Article 30)
        → WebFetch EUR-Lex /TXT/ page, extract Article 30
        → Found: "Member States shall lay down penalties..."
        → References Article 5 (obligations) and Article 10 (reporting)

Step 3: Verify internal references
        → WebFetch same page, extract Articles 5 and 10
        → Article 5: Main compliance obligations
        → Article 10: Notification requirements

Step 4: Check for external references
        → Article 30 references Regulation (EU) 20YY/YYY
        → GoodLegal API: "320YYRYYYY"
        → Extract relevant provisions

Step 5: Check /ALL/ for implementing acts
        → WebFetch EUR-Lex /ALL/?uri=CELEX:320XXLXXXX
        → Found: Commission Implementing Regulation 20ZZ/ZZZ
        → Retrieve and review implementing details

Reference Chain Documentation

When answering legal questions, document the reference chain:

**Question:** What are the reporting obligations under Directive 20XX/XXX?

**Answer:**
- Article 10: Notification within 72 hours
- Article 11: Content requirements (see Annex II)

**Internal references verified:**
- Article 5 → Scope of application
- Annex II → Notification template

**External references verified:**
- Regulation 20YY/YYY Article 15 → Definitions
- Commission Implementing Regulation 20ZZ/ZZZ → Technical standards

**Related acts from /ALL/ page:**
- 3 implementing regulations
- 1 delegated act
- 2 amending acts

Decision Flow

User request
    │
    ├─► Full text needed?
    │       └─► GoodLegal API (CELEX ID or reference)
    │
    ├─► Search by concept?
    │       └─► EUR-Lex Search via WebFetch
    │           Read Form field to identify document type
    │
    ├─► Legal status / modifications?
    │       └─► EUR-Lex /ALL/ page via WebFetch
    │
    ├─► Transposition status?
    │       └─► EUR-Lex /NIM/ page via WebFetch
    │
    └─► Legislative procedure?
            └─► EUR-Lex /HIS/ page via WebFetch

Parallel Search Strategy

For comprehensive research, launch multiple WebFetch calls in parallel:

# Search pages 1-5 simultaneously
Page 1: .../search.html?scope=EURLEX&text=QUERY&lang=en&type=quick&locale=en
Page 2: .../search.html?scope=EURLEX&text=QUERY&lang=en&type=quick&locale=en&page=2
Page 3: .../search.html?scope=EURLEX&text=QUERY&lang=en&type=quick&locale=en&page=3
Page 4: .../search.html?scope=EURLEX&text=QUERY&lang=en&type=quick&locale=en&page=4
Page 5: .../search.html?scope=EURLEX&text=QUERY&lang=en&type=quick&locale=en&page=5

Then filter results by Form field (Judgment, Directive, Regulation, etc.) based on user needs.

Error Handling

No Results

• Try different search terms
• Try both EN and User's language
• Use EUR-Lex Search as fallback
• Check CELEX ID format

EUR-Lex National Text Unavailable

When EUR-Lex /NIM/ links show "Texte non disponible" or "Text not available", follow the National Transposition Text Retrieval workflow below.

Method 3: National Transposition Texts

Problem

EUR-Lex /NIM/ pages list national transposition measures but the links to actual text often fail ("Texte non disponible" / "Text not available"). The /NIM/ page provides:

• Name of the national measure (e.g., "Decreto Legislativo 10 marzo 2023, n. 24")
• Official Journal reference (e.g., "Gazzetta Ufficiale n. 63 del 15 marzo 2023")
• Transposition deadline

Workflow

Step 1: EUR-Lex /NIM/ Page
        │
        └─► WebFetch https://eur-lex.europa.eu/legal-content/EN/NIM/?uri=CELEX:{CELEX}
            Extract: measure name, Official Journal reference, date
        │
        ▼
Step 2: Try EUR-Lex Link
        │
        └─► Click/fetch the link provided on the /NIM/ page
            (e.g., https://eur-lex.europa.eu/legal-content/FR/TXT/?uri=NIM:202302012)
        │
        ├─► Text available? → USE IT ✓
        │
        └─► "Texte non disponible" / "Text not available"?
                │
                ▼
Step 3: Official National Database (see table below)
        │
        └─► Use the measure reference from Step 1
            Search in the official national legal database
            (e.g., Normattiva for Italy, Légifrance for France)
        │
        ├─► Text found? → USE IT ✓
        │
        └─► Not found?
                │
                ▼
Step 4: Web Search (last resort)
        │
        └─► Search for official sources using:
            - Measure name + number + year
            - Official Journal reference
            - Filter by official government domains (.gov, .gv, .gouv, etc.)
