22. University of Tromsø22 Preparatory works ‘The Soviet delegation …wished to make clear that the proposed text of article [221] should not be held to give the coastal State more extensive rights of intervention in cases of maritime casualty than the rights of intervention it already enjoyed under the terms of the [Intervention Convention]. The words “pursuant to international law, both customary and conventional” meant only one thing: they gave States which were not parties to the 1969 Convention the right to intervene within the limits defined by that Convention.’
