Was Albania responsible? Was the UK responsible?
UK claimed right of intervention in order to secure evidence in Albania for submission to an international tribunal. There was high probability that mines were laid down by Yugoslavia
It is clear that the knowledge of the mine laying cannot be imputed to the Albanian government by reason merely of the fact that a minefield discovered in Albanian territorial waters caused the explosions of which the British warships were the victims. It is true…that a state on whose territory or in whose waters an act contrary to international law has occurred, may be called upon to give an explanation. It is also true that that state cannot evade such request by limiting itself to a reply that it is ignorant of the circumstances of the act and of its authors…but it cannot be concluded from the mere fact of the control exercised by a State over its territory and waters that that state necessarily knew, or ought to have know or any unlawful act perpetrated therein. This fact, by itself and apart from other circumstances, neither involves prima facie responsibility nor shifts the burden of proof.
