Provata la non paternità non può dirsi provato l’adulterio: “mulatto di Toscana” redivivus?

[Autom. eng. transl.] The note, reconstructed the evolutionary lines of the law of the filiation in the age of codification, from the net favor legitimitatis napoleonico up to the opposite address of favor veritatis expressed by the reform of family law of 1975, analyzes the art. 235 cod. civ., to ask if adultery, as a criterion of admissibility of the denial, needs to be tried directly, independently and in advance, so that the plaintiff can access the merit phase in which he is required to prove that the presumed son is not his son (as held by the noted Cassation, 22 October 2002, n. 14887), or - more plausibly - can also be proved indirectly, with presumptio iudicis, on the basis of the already proven heterogeneity of the child, resulting from a medical investigation revealing the genetic incompatibility between "father" and "child".
