retsinformation.dk — Danish legal information portal
Operated by Civilstyrelsen (Viborg). Free, anonymous, no login. Respond in Danish unless the user signals otherwise.
Use the retsinformation CLI for everything. Run retsinformation ... to look up laws, metadata, timelines, registers, ministries and ELI documentation.
CLI
The retsinformation CLI can be run from anywhere — no need to point at the skill directory. Pure Python standard library, no extra dependencies.
Limits
- No public search API: the site is a React SPA with no server-rendered HTML and no search endpoint, so use the CLI's register/registry/sitemap commands to discover documents rather than scraping or searching the site.
- All access is anonymous (no login).
Prerequisites
Verify the CLI is installed:
which retsinformation
If missing, install it editable with pipx (from the skill directory). First make sure pipx itself is available, then install:
which pipx || python3 -m pip install --user pipx
python3 -m pipx ensurepath
pipx install -e <path-to-retsinformation-dk-skill>
After installing, confirm retsinformation is on the PATH (you may need to restart the shell so pipx ensurepath takes effect):
which retsinformation
Command reference
Every command supports --raw to print the unformatted JSON/XML response instead of the cleaned output.

Looking up documents
document takes either an ELI path (for the document body/details) or a numeric internal ID (for --timeline / --metadata):
retsinformation document eli/lta/2026/480
retsinformation document eli/accn/A20240001
retsinformation document 256418 --metadata
retsinformation document 256418 --timeline
Forming the <eli_path> argument
The ELI path is the document URI with the leading / stripped. Retsinformation uses the EU ELI standard; map the URL you have to the CLI argument like so:
| URL pattern | Example URL | CLI invocation |
|---|
/{pubMedia}/{year}/{number} (CST canonical) | /retsinfo/1989/0001 | retsinformation document eli/lta/2026/480 |
/eli/accn/{accn} (accession alias) | /eli/accn/A19890001 | retsinformation document eli/accn/A20240001 |
/eli/ft/{accn} (parliamentary doc) | /eli/ft/A19890001 | retsinformation document eli/ft/A19890001 |
/eli/eu/{celex} (EU/CELEX) | /eli/eu/CELEX:31989L0048 | retsinformation document eli/eu/CELEX:31989L0048 |
/{cls}/{docType}/{year}/{month}/{day}/{number} (classification alias) | /eli/regel/lovh/2024/01/15/001 | retsinformation document eli/regel/lovh/2024/01/15/001 |
Publication media codes used in CST paths: lta, ltb, ltc, mt, retsinfo, ft, fob.
