The EUR-Lex legal notice (https://eur-lex.europa.eu/content/legal-notice/legal-notice.html, read 2026-10-06) says the Commission's document reuse policy is based on Decision 2011/833/EU and that, unless otherwise specified, the legal documents published in EUR-Lex may be re-used for commercial or non-commercial purposes. Decision 2011/833/EU (https://eur-lex.europa.eu/eli/dec/2011/833/oj/eng) Art. 4 makes documents available for reuse without charge or application; Art. 6(2) allows the conditions of source acknowledgement and no distortion of the original meaning. The notice's Creative Commons BY 4.0 grant covers only EUR-Lex editorial content, summaries of EU legislation and consolidated texts, not the acts as such, so the corpus is not labelled CC BY 4.0. This is a reuse permission, not an exclusion from copyright: Art. 4 of the Polish Copyright Act does not apply to EU acts and is not relied on.

Provenance

Pulled from SpeakLeash's public redistribution (speakleash-ds-pub, key eurlex_corpus) of EUR-Lex. SpeakLeash is an intermediate aggregator: its own terms for the corpus were not checked, and the upstream EUR-Lex terms above are the basis. Documents are Polish-language EUR-Lex texts: Official Journal L and C items, consolidated texts, Court of Justice documents and Commission documents.

Legal scope note

Third-party material is not covered. The notice and Decision 2011/833/EU Art. 2(2)(a)-(b) exclude documents covered by industrial property rights or third-party intellectual property rights, and the notice says the International Accounting Standards may carry special conditions of use. 92 documents (74.1M characters, 1.24% of v0.2.5) carried the IASB notice allowing reproduction within the EEA and reserving all rights outside it: 64 Official Journal acts adopting or amending IAS/IFRS and 28 consolidated versions (Regulations 1126/2008, 1725/2003, 475/2012, 1361/2014). They were removed in v0.2.6 (243,060 -> 242,968 documents). 97 documents contain a (c) sign; 33 of them are third-party credits or short data citations (photographs, maps, OECD, IHS Markit, McKinsey, Springer), the rest EU credits or extraction noise; they were kept. Ids and counts are in eurlex.third-party-scan.json and eurlex.license-evidence.json; recall for third-party text the patterns do not target is unknown. Decision 2011/833/EU itself covers documents held by the Commission or the Publications Office; acts of other institutions (Council, Parliament, ECB, EESC, CJEU) rest on the notice's general sentence alone, and whether those bodies publish their own reuse terms was not checked.

drop documents < 200 chars: 0
drop non-Polish (diacritic ratio): 0
exact cross-source dedup (sha1): 0
OCR alpha-ratio < 0.70 (OCR sources only): 0
