Franco Ferrari has just published a paper focusing on the interpretation of the CISG in which he identifies two interpretative trends, both of which are disruptive of the uniformity aimed at by the drafters of the CISG; the homeward trend and the outward trend. As for the homeward trend, it has been defined as the tendency of interpreters of the CISG to read the expressions used in the CISG in light of the domestic law in which the interpreter was trained. On the other hand, the “outward trend”, an expression coined by Professor Ferrari in earlier writings, is defined by Professor Ferrari as the “the tendency of those interpreting a uniform law instrument to project foreign law onto the provisions of an international instrument where these provisions refer to legal concepts unknown in the system in which the interpreter is trained”. As Professor Ferrari points out in his paper, both trends go against the very idea behind the creation of a uniform sales law and must therefore be combatted. In his paper, Professor Ferrari makes a suggestion on how to do so successfully. The paper is entitled Tendencia nacionalista vs tendencia importadora en la jurisprudencia de la CVIM, and is published in The Transnational Sales Contract. 40 years influence on the CISG on National Jurisdictions edited by F. Benatti et al., Milan, 2022, p. 199-217.
