@Olivier5,
Actually, there are controversies about any prize, even (or especially?) about small local ones.
Notorious controversies have been over Nobel Prizes for Literature and Economics as well.
Sabb will know it better, but there has been a Danish book (Intet, by Janne Teller), which got the
Kulturministeriets børnebogspris ("Book prize of the culture ministry") and the
Michael L. Printz Award, but was forbidden in Danish schools (and some libraries) for some time.
