The legal basis for that view is article 70 of the Vienna Convention on the Law of Treaties, which provides that withdrawal from a treaty does not absolve the State party from any obligation it had prior to exercising its right to withdrawal.
Son fondement juridique est l &apos; article 70 de la Convention de Vienne sur le droit des traités qui établit que le retrait d &apos; un traité n &apos; autorise nullement un État partie à ne plus s &apos; acquitter d &apos; obligations antérieures à ce retrait qui est pleinement son droit.
