In the early 1990s, a revision of the Belgian Constitution made it more difficult to change the language status of the concerned municipalities by requiring that any such change had to gain a majority in each of the two language groups in the House of Representatives and the Senate. Previously, an overall majority would have been enough, which could have in theory allowed a near unanimity of Flemish representatives to impose an abolition of the facilities against the unanimous wish of the French-speaking representatives. This revision of the Constitution was widely seen by French speakers as a recognition that language facilities had permanent status.
