For the Ministerie van BZK we investigated a concrete question: can a sovereign multi-agent setup really do production work on a recognisable government task? As a proof of concept we chose the handling of objections against parking fines in a municipal context.
A civil servant uploads an objection and gets back a draft decision. In doing so, the system finds the right regulations, links earlier cases similar to this one via graph-RAG, and delivers a compliance checklist. Several agents each take on a sub-step.
The civil servant remains ultimately responsible and signs off. At every checkpoint there is a moment of control, and all steps are recorded in an audit log. Human in the loop is not an extra here, but the core of the setup.
The solution runs sovereignly at Nebul on small open-source models. All personal data stays within its own infrastructure, so sensitive information does not leave the environment.
The aim was to show that a sovereign multi-agent setup can handle production work and generalises to other forms of document generation in government. This is a proof of concept, not a production system.
