Graubünden legal source types covered
Graubünden coverage currently centres on cantonal tax administration materials — tariffs, practice determinations, and official guidance. Primary cantonal legislation, legislative history, and case law are covered where available.
Legislation & Regulations
Withholding-tax tariffs and rate schedules (Tarife) and cantonal practice determinations (Praxisfestlegungen) interpreting the articles of the Graubünden tax law, taken directly from the Steuerverwaltung Graubünden portals on gr.ch. Consolidated cantonal statutes are added where available.
Legislative History
Amendment records and prior versions of cantonal tax tariffs and guidance where available, version by version, each tied to its source. Broader parliamentary materials from the Grosser Rat are not yet in the Graubünden corpus.
Regulatory Guidance & Enforcement
Circulars (Kreisschreiben), guidance leaflets (Wegleitungen / Merkblätter), and practice notes (Praxisfestlegungen) from the Steuerverwaltung Graubünden — the strongest part of current coverage — spanning withholding tax, deductions, and assessment practice.
Case Law
Decisions of the Graubünden cantonal courts and the Verwaltungsgericht are covered where available; cantonal case law is not yet part of the Graubünden corpus and can be requested.

Why Lawstronaut for Graubünden legal research
Graubünden legal information is spread across cantonal administration portals published in three languages, with tariffs, circulars, and practice notes updated on their own cadence. 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 Graubünden legal coverage
Graubünden (Grisons; Grigioni; Grischun) is a canton of Switzerland and the country's only officially trilingual canton, with German, Italian, and Romansh as official languages. It is a civil-law jurisdiction operating within the Swiss federal system: cantonal statutes sit in the Bündner Rechtsbuch, the Grosser Rat is the cantonal parliament, and the cantonal courts and Verwaltungsgericht handle adjudication. Lawstronaut's current Graubünden corpus centres on the cantonal tax administration (Steuerverwaltung Graubünden), which publishes withholding-tax tariffs, practice determinations, circulars, and guidance across German, Italian, and Romansh portals on gr.ch.
Cantonal tax practice moves on an annual and rolling cadence: withholding-tax tariffs are reissued each year, circulars and practice notes are revised as assessment practice changes, and the trilingual publications must stay aligned. Point-in-time data straight from the source is what keeps a Graubünden tax-law answer correct today.
