Mr. Chair, from a non-legal standpoint, that is, simply from a linguistic point of view, the words “plausible” and “un risque important” don't mean the same thing to me. The word “plausible” evokes the likelihood that something will occur, so the level of risk is much lower. It's not in the same category as a substantial risk. They might not be synonyms. I don't want to pull out my French dictionary, but these words don't necessarily belong in the same category.
