This is a discussion about the submission for law / fr.
The license is Licence Ouverte / Open Licence (the license of the French government) which is obviously an open license.
It is stated on this page: LEGI: Codes, lois et règlements consolidés - data.gouv.fr
See discussion here Entry for National Laws / FRANCE - #21 by RouxRC
It was stated as non open because in addition to the open licence, a specific decree applies to this specific dataset creating legal insecurities towards its use. Surprisingly, they removed reference to it in the dateset description though, but it still remains in the law: https://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000413818 (article 4)
