Vertaling van "defined quite unclearly " (Engels → Frans) :

The authorities of the national and European regulator are defined quite unclearly and the boundaries between them are significantly blurred.
La définition des compétences des autorités de surveillance nationales et européennes manque de clarté et il demeure une confusion quant à la délimitation de leurs frontières respectives.

This is an inherently vague and ill-defined concept and one on which valuable investments, investments which could be on balance, long term, very valuable for the Canadian economy, may simply not happen because of a rather vague concept that seems to be applied at times and in ways that are quite unclear to investors and are certainly unclear to me.
Ce concept foncièrement vague et mal conçu nuit aux investissements qui, à long terme, pourraient être très profitables à l'économie canadienne, car il est appliqué sporadiquement et de façon nébuleuse aux yeux des investisseurs.
