# Cross-Border Legal Core (EU PIL Subset)

A curated subset of **EU private international law provisions** used as the retrieval corpus for the [Cross-Border Legal RAG](https://huggingface.co/spaces/SehaanCuda/crossborder-legal-rag) system.

> **Educational use only — Not legal advice.**

---

## What is in this dataset?

Selected mandatory provisions from three foundational EU regulations governing choice-of-law and jurisdiction in cross-border civil and commercial matters:

| Instrument | CELEX | Provisions Included |
|---|---|---|
| **Rome I** — Reg. (EC) No 593/2008 | 32008R0593 | Arts. 4, 6, 8 (sub-articles split) |
| **Rome II** — Reg. (EC) No 864/2007 | 32007R0864 | Art. 4 (sub-articles split) |
| **Brussels Ia** — Reg. (EU) No 1215/2012 | 32012R1215 | Art. 7(1), 7(2) |

Each record corresponds to one meaningful sub-article chunk, optimised for dense retrieval (~150–250 tokens per chunk).

## Intended Use

- Educational legal research
- Retrieval-Augmented Generation (RAG) experiments in the legal domain
- Benchmarking embedding models on EU statutory text

---

## Limitations

- **Partial coverage**: Only the specific sub-articles most relevant to cross-border PIL scenarios are included.
- **EU focus**: Does not cover national laws, case law, or non-EU jurisdictions.
- **Static snapshot**: Regulation amendments enacted after the scrape date are not reflected.
- **Not legal advice**: This dataset must not be used as the sole basis for legal decisions.
