Particularly relevant in civil law countries such as Italy and Germany-and especially in Portugal-this topic has generated intense doctrinal debate. In an effort to circumvent the constraints imposed by the traditional model of the plea of res judicata and the triple identity test, Portuguese legal scholarship developed the concept of the authority of res judicata. However, the vague contours of this concept have led to doctrinal uncertainty and inconsistency.
Does res judicata extend only to the operative part of the judgment, or does it also encompass its reasoning? Is only the claim precluded, or also the cause of action?
