- E-Sbírka — official e-Collection of Laws (e-sbirka.gov.cz)
- Zákony pro lidi (zakonyprolidi.cz)
- Ústavní soud — Constitutional Court (usoud.cz)
- Úřad pro ochranu osobních údajů — ÚOOÚ (uoou.gov.cz)
Czech legal source types covered
Czech legal coverage includes primary legislation, secondary legislation, regulatory materials, constitutional case law, guidance, and point-in-time legislative versions where available.
Legislation & Regulations
Zákony, nařízení vlády, vyhlášky, and other instruments published in the Sbírka zákonů, taken directly from e-Sbírka — the official electronic Collection of Laws — with consolidated texts also drawn from Zákony pro lidi.
Legislative History
Promulgated texts (vyhlášené znění) and successive consolidated versions of each act from e-Sbírka where available, version by version, each tied to its source.
Regulatory Guidance & Enforcement
Opinions, guidance, annual reports, and enforcement-related materials from the Czech data protection authority, the Úřad pro ochranu osobních údajů (ÚOOÚ).
Case Law
Decisions of the Ústavní soud — the Czech Constitutional Court — from its official portal, where available.

Why Lawstronaut for Czech legal research
Czech legal information is spread across the official Collection of Laws, consolidated statute services, the Constitutional Court, and regulators. For humans, that means slow research. For AI systems, it's a bigger problem: fragmented source access, inconsistent formats, missing provenance, and weak citation trails.
Lawstronaut turns those sources into one structured legal data layer — source links, metadata, full text, versioning, and API/MCP access. Your product or agent retrieves the legal source directly instead of relying on generic web search or unverified model memory. Every answer carries a citation, a timestamp, and a link to the official document — the provenance that makes a legal research platform defensible to auditors and regulators.
About Czech Republic legal coverage
The Czech Republic is a civil-law jurisdiction. Since 2024, legislation in the Sbírka zákonů (Collection of Laws) has been published through e-Sbírka, the official electronic Collection of Laws operated by the state, which carries promulgated texts and consolidated point-in-time versions of every act. Zákony pro lidi provides a widely used consolidated view of the same legislation. Constitutional case law is published by the Ústavní soud in Brno, and data protection oversight sits with the Úřad pro ochranu osobních údajů (ÚOOÚ). Records are published in Czech.
Czech law moves quickly: consolidated texts on e-Sbírka change continuously as amendments take effect on staggered dates, the ÚOOÚ publishes a steady stream of guidance, and EU-derived rules — the GDPR alongside Act No. 110/2019 Sb. — keep evolving. Point-in-time data straight from the source is what keeps a Czech legal research answer correct today.
