The extension to the labour collective agreements, through the 2015 Loi "Macron", of the so called request for opinion (saisine pour avis) to the Cour de cassation on the grounds of the interpretation of civil law represents an occasion to investigate an institute introduced in the transalpine and Italian context (via Art. 420 bis. c.p.c.) with analogous aims, that is to reduce the disputes through the revitalization of the interpretative function of the Court of last instance. The essay emphasises how, independently from the distance that characterizes the normative aspects of the two systems, their use is very modest in both legal systems, which suggests an incisive retelling together with a systematic reflection on the prospects for reform of the civil (and labour) trial and of the means to accede to the Court of last instance.
