BGE / ATF / DTF Citation Format

Full Format by Language

Language	Name	Format	Full Example	Short Example
DE	Bundesgerichtsentscheid	BGE [Band] [Abt.] [Seite] E. [Erw.] S. [Seite]	BGE 145 III 229 E. 4.2 S. 235	BGE 145 III 229 E. 4.2

EN	Federal Supreme Court Decision	BGE [volume] [section] [page], consideration [no.]	BGE 145 III 229, consideration 4.2	BGE 145 III 229, cons. 4.2

Strong	Established BGE line, clear statutory text, consistent doctrine, undisputed (unstr./indisc./pacifico)
Moderate	Some BGE support, interpretive flexibility, majority doctrine (h.M./op. dom.)
Weak	Novel argument, contrary BGE exists, minority doctrine (a.M./op. diff.), disputed (str./contr.)

Common Citation Errors and Corrections

Error	Problem	Correction
art. 97 Abs. 1 OR	Mixed FR/DE: lowercase "art." with German "Abs."	Art. 97 Abs. 1 OR (DE) or art. 97 al. 1 CO (FR)
Art. 97 Abs. 1 CO	DE format with FR statute abbreviation	Art. 97 Abs. 1 OR (DE) or art. 97 al. 1 CO (FR)

Cross-Language Citation Conversion

When converting citations between languages, change only:

1. Statute abbreviation (OR/CO, ZGB/CC, StGB/CP, BV/Cst./Cost.)
2. Element labels (Art./art., Abs./al./cpv., Bst./let./lett.)
3. BGE prefix (BGE/ATF/DTF)
4. Consideration label (E./consid./consid.)

Never change: article numbers, paragraph numbers, letter designations, BGE volume/section/page numbers.

MCP Tools for Citation Work

Use these tools rather than constructing or guessing citations:

Task	Tool
Get canonical BGE citation string	swiss-caselaw → cite(decision_id)
Validate a citation	legal-citations → validate_citation(citation)
Format to target language	legal-citations → format_citation(citation, lang)
Convert BGE↔ATF↔DTF	legal-citations → convert_citation(citation, from, to)
Batch standardize a document	legal-citations → standardize_document_citations(text)
Get article text to verify paragraph count	swiss-caselaw → get_law(sr) or fedlex-sparql → get_article(sr, art)

Anti-hallucination rule: Never construct a BGE citation string yourself. BGE volume = year − 1874, and section codes depend on the legal area (I–VI). Even a small error produces an invalid citation. Always retrieve via cite() or validate_citation().

Quality Rules

Before delivering any output containing legal citations:

• Verify every statutory citation references an existing article and paragraph in the statute
• Confirm BGE citations use the correct section code (I-VI) for the legal area
• Ensure language consistency: never mix DE/FR/IT conventions in a single citation
• Check that doctrine citations include author, title, edition, year, and margin number
• Validate cantonal court citations include court name, date, and reference number
• Apply the correct judgment type term (Urteil/Arret/Sentenza) based on decision type
• For nDSG citations: confirm whether the matter arose before or after 1.9.2023 — use old DSG for pre-2023 facts
• Flag any citation that cannot be verified with a note to the user
