Collective shops of independent traders already created through a legal person may, by way of adaptation or transformation, be placed under the regime provided for by this chapter. Any member may, by way of summary proceedings, request the appointment of a representative specifically responsible for convening the meeting for the purpose of deciding on such adaptations or transformations. Notwithstanding any provision to the contrary, such decisions are taken by a majority in number of the members making up the legal person. Those who have not voted may, however, withdraw by requesting the redemption of their securities, shares or units, under the conditions provided for in articles L. 125-17 and L. 125-18.
