Sources, by tier and how they are delivered

We work from primary sources: EU legislation through its official portals, national registers, and the published guidance of the office that decides a matter. A page states only what one of these supports.

Four levels of reference

1. Named exactly. Where a record exists, the instrument or source is named in full, not paraphrased.
2. Generalised. Where the phenomenon is known but no single record fits, we refer to "the applicable regulation" or "the rules of the relevant authority" rather than cite a requisite we cannot verify.
3. Mechanism. Where a figure is not available, we describe how it is set — for example, that a fee is fixed by the authority and published in its own schedule — rather than quote a number.
4. Silence. Where a section would need a fact we do not hold, it is shortened or omitted. A missing section is better than an invented requisite.

Advisory pages and reports

An advisory page answers what your rights are and how a procedure runs. A report, where offered, states what can be established about a specific object from named registers, with the date each item was retrieved and an explicit limit on what the source does not show. The two are kept separate on purpose.
