Vaquill AI’s Open US Law corpus, a structured compilation of roughly five million US statutory, regulatory, constitutional and court-rule sections, relicensed its data from CC BY 4.0 to CC BY-NC 4.0 starting with the v2026.09 snapshot, while the Apache-2.0 scrapers that build it stay free for commercial use and snapshots published before v2026.09 keep their original terms. The README says the compilation is free for research, teaching, legal aid, journalism and other non-commercial use with attribution, and that commercial use requires an emailed licence, framing the change as keeping bulk access to the law open while charging those who build commercial products on it.
