The huts already built or to be build in the future to shelter the co-users shall also remain open but the persons who had built them as well as their successors shall have a preferential right to occupy them and, therefore, if upon their arrival [the hut] was occupied so he can not access it, the first person who had accessed in shall leave it [the hut] and, if there was not enough room as a consequence of having brought more persons from his house or horses, the person following the first who had left shall leave and succesively the rest in this way. For the purposes of this rule, the labourers and horses brought for the work shall be considered part of the owner's family.
