6. Any person who settles on a site where occupation of the land is commonly known to be subject to special restrictions by reason of a major or minor disaster risk without abiding by such restrictions is presumed to accept the risk involved.
However, such presumption may not be invoked against a person by a public authority if the public authority authorized the person to settle on the site without informing the person of the risk.
This section does not apply with respect to structures and uses existing on 20 December 2001, unless the destination of an immovable is changed after that date, which shall be considered a new settlement for the purposes of this section.
