Every answer, with a source.
Roughly 12,000 tax documents, searchable.

What is in it

| Case law | Rulings from the Supreme Court, courts of appeal and district courts, searchable by ECLI and topic. |
| Decrees | Policy decrees from the Ministry of Finance, published in the Government Gazette. |

§ 02 / Research
Cited research
In the portal you chat with the knowledge base the way you would ask a colleague to look something up. Every answer comes with numbered footnotes to the source, in the standard legal citation style, as a clickable link to that source's knowledge base page. The knowledge base only cites what it actually retrieves: no invented citations.
