What makes the Brussels casino case particularly complicated is that several separate issues are now unfolding at the same time.
There is the administrative dispute over how the concession bids were scored and justified.
There is the political and ethical debate around relationships between public officials, football and companies connected to the tender.
And there is now the judicial investigation, opened after an anonymous complaint and currently directed against unknown persons.
Those issues may overlap factually, but they should not be treated as identical.
The Council of State has made findings about the concession procedure. Political opponents have raised questions about possible conflicts of interest. Prosecutors are now carrying out checks following a complaint.
None of those facts, on its own, establishes criminal wrongdoing by any named individual.
