571. A class action is a procedural means enabling a person who is a member of a class of persons to sue, without a mandate, on behalf of all the members of the class and to represent the class.
In addition to natural persons, legal persons established for a private interest, partnerships and associations or other groups not endowed with juridical personality may be members of the class.
A legal person established for a private interest, a partnership or an association or another group not endowed with juridical personality may, even without being a member of a class, ask to represent the class if the director, partner or member designated by that entity is a member of the class on behalf of which the entity is seeking to institute a class action, and the designee’s interest is related to the purposes for which the entity was constituted.
