Zurich legal data from official sources, structured for AI and legaltech.
Zurich laws, regulations, and court decisions live across the consolidated cantonal law collection (Zürcher Gesetzessammlung, LS), the cantonal gazette (Amtsblatt des Kantons Zürich), the Kantonsrat, cantonal directorates and offices, and the courts — within the framework of Swiss federal law published on Fedlex. Lawstronaut structures legal data from official sources into one format used across more than 150 jurisdictions — with every record linked to its official source. Structured Zurich coverage is not yet live; Team and Enterprise customers can request priority onboarding of the sources below.

Which instrument establishes the constitutional framework of the Canton of Zurich?
The Constitution of the Canton of Zurich of 27 February 2005 (Verfassung des Kantons Zürich), in force since 1 January 2006 and as amended, is the cantonal constitution setting out Zurich's governmental structure — the Kantonsrat, the Regierungsrat, and the cantonal courts. It is published in the consolidated cantonal law collection (Zürcher Gesetzessammlung, LS 101) and listed in the Swiss federal systematic collection as SR 131.211.

Why Lawstronaut for Zurich legal research
Zurich legal information is spread across the cantonal law collection, the cantonal gazette, the Kantonsrat, cantonal directorates and regulators, the cantonal courts, and the Swiss federal law portal. 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 Zurich legal coverage
Zurich is the most populous canton of Switzerland and its economic centre, operating within the Swiss civil-law tradition. Federal law — the Swiss Civil Code, the Code of Obligations, and federal statutes — applies across the canton and is published on Fedlex, while cantonal law sits in the Zürcher Gesetzessammlung (LS) and is announced in the Amtsblatt des Kantons Zürich. The cantonal constitution of 27 February 2005 frames the institutions: the 180-member Kantonsrat legislates, the Regierungsrat governs through the Staatskanzlei and cantonal directorates, and the Obergericht sits above the district courts (Bezirksgerichte), alongside the specialised Handelsgericht (commercial court), Verwaltungsgericht, and Sozialversicherungsgericht, with the Swiss Federal Supreme Court above them. Legal materials are published in German.
Zurich's cantonal law changes in step with periodic reform: the canton continually revises its tax, planning and construction, and administrative statutes as Swiss federal law evolves, and has modernised its judicial organisation and cantonal ordinances in recent years — so citations to superseded cantonal provisions can be wrong. Point-in-time data straight from the source is what keeps a Zurich legal research answer correct today.
