Most lawyers fear that they will no longer be considered experts if they use plain language. This is a point of frustration for lawyers, because nothing makes us feel more sophisticated than Latin formulas. But it is the best lawyers and the most recognized experts who manage to make the law accessible and intelligible. It is no coincidence that an ISO standard for clear language will be published in 2023. Let us recall in passing that in France there is a principle of constitutional value of the clarity of the law, that our two highest courts have each produced a vademecum on the clarity of judgments and that a good number of texts in France, within the European Union and in the rest of the world impose clarity and accessibility.
