This article is an attempt to study the relationship between Creole language and Language law in Mauritius, bearing in mind the fact that Creole is the spoken language most widely used in Mauritius while being one of the least recognized languages both officially and institutionally. We will try to stress on the one hand, the particular choice of the implicit mode by the law-maker when it comes to pave the way to the use of Creole in official situations and, on the other hand, the frequent disparity between what the law says and what people actually do when it comes to linguistic practices.
