But I really am surprised by this use of "community" in a ruling from such a high instance. And, as you point out, the term "communauté française" (re France), has an inglorious past, especially
Communauté française - Wikipédia
Sous le régime de Vichy, l'expression communauté française servait à désigner l'ensemble des Français de souche, selon l'idéologie aryaniste, avec l'objectif de spécialement exclure les Juifs de la nationalité française.
(Under the Vichy régime, the term "French community" was used to indicate those "of French stock", according to the Aryanist ideology, with the aim in particular of excluding Jews from French nationality.)
As for me, "communauté française" may refer to the (failed) attempt to build a commonwealth-like association with former colonies at the end of the fifties.
Do you know where this expression comes from, apart from wikipedia? Is it of a widespread use abroad to design the 1939-1944 period or policies? A free fox in a free henhouse!
