El tercero extraño al litigio y su posible legitimación en procesos de conocimiento.

Abstract

There has always been the question of who and under what condition they can and should intervene in the process and whose preliminary response has been that of all those people directly affected by the decision, since the participation of strangers or third parties should not be allowed within it to the litigious issue since a matter should be discussed only in the presence of the persons to whom the decision will be linked; however, there are occasions when a decision, although it does not display its effects towards third parties, may result in a substantial relationship between a third party and any of the litigants. Because of this event is that there is a need to study the participation of third parties outside the litigious issue, who try to enter the process in order to safeguard their own issue that, although not in debate, can be indirectly affected by the judicial decision. For this reason we must examine whether it is admitted that the participation of a third party action should or should not be limited, which will help us answer the next big question to what extent the third party outside the litigious issue may be affected by the court decision in such a way that its admission to the process is justified by the mere fact of arguing and justifying an eventual affectation?.
