Lo "Iussum" fra diritto processuale e diritto sostanziale: l'attività negoziale con il terzo

The thesis considers the topic of the processes of will within the collective groups of people.The point of view from which you look at this topic is the prompt iussum with which the pater familias/dominus tasked a subordinate, filius or servus, to accomplish some negotiation activity with the third, thereby creating a possible liability of the same pater familias/dominus through the "actio quod iussu", one of those actions, perhaps the prototype of them, that Glossatori defined, by combining in a single genus, as actiones adiecticiae qualitatis.The hypothesis of research supported in this work is that through the iussum is possible to examine, without the limits related to the use of modern abstract legal categories such as those of legal entity or representation, the formation of the will of men in communities.The objective of the thesis is to bring out, for the solution of the single method of legal activity carried out by a plurality of people, an alternative in the ‘binomial’ ‘societas/corpus concreto’ "(as theoretical conception) connected with the “iter of the will dialectically articulated in the general " iussum" of the associates and in the particular administratio of their magistri/magistratus” (as operative system).
