The flags are often a marketing tool and routinely display brand names like the beer brand Jupiler or the Francophone daily La DH. In Het Nieuwsblad Michel Maus, a professor of tax law, warns that some municipalities levy municipal taxes on advertising and displaying such a flag on the front or your house could easily cost you 50 euros.
Prof Maus: "As a rule exceptions are not made for soccer matches. The municipalities should insist on payment. Otherwise they are setting a precedent."
Municipalities affected include Aalst, De Haan, Hasselt.
Het Laatste Nieuws reports that a Flemish nationalist councillor in Aarschot has asked the local council if flags displaying the beer brand name can be lawfully displayed in his home town.
Jos Bruyninckx: "These flags with advertising for a Walloon brand of beer conflict with our advertising rules. Our regulations stipulate that if you advertise a product that you do not sell, you are bound to pay 50 euros to municipal coffers."
