Usura e interessi di mora: la discutibile posizione assunta dalle Sezioni Unite

The paper examines, with a critical approach, the ruling of the Supreme Court n. 19597 of 2020 on the applicability of the anti-usury discipline to interest ex art. 1224 of the Italian Civil Code. After reviewing the arguments in support of the various theses accepted in doctrine and jurisprudence, the contents of the solution proposed by the Supreme Court are illustrated, highlighting the methodological criticalities — with particular regard to the so-called “Asymmetric application of the principle of symmetry”—the weakness of the ratio decidendi and the overcoming of the boundaries of hermeneutic activity by the Court.
