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).
