The case concerned the attempted reliance, in relations between Italy and India, on the 1873 bilateral extradition convention concluded between Italy and the United Kingdom, at a time when the United Kingdom exercised colonial authority over India. The Rome Court of Appeal examined whether treaties concluded by a colonial power could continue to apply to a newly independent successor State notwithstanding the general “clean slate” principle. It held that devolution agreements between the former colonial power and the newly independent State are, in themselves, res inter alios acta and cannot be invoked against the original treaty counterparty unless followed by a formal act of succession, in the case of multilateral treaties, or by a specific agreement between the successor State and the original counterparty, usually by exchange of notes, in the case of bilateral treaties. The Court further observed that continuation could also be inferred from unequivocal conduct showing both States’ intention to remain bound by the treaty. In the absence of such formal steps or conclusive conduct, the Court held that the 1873 Italy–United Kingdom extradition convention was not applicable between Italy and India.
