"This view renders it unnecessary finally to discuss the burden of proof, but in my present view, if there are circumstances suggesting that another cause than a peril insured against was the dominant or effective cause of the entry of sea water into the ship . . . and an examination of all the evidence leaves the Court doubtful what is the real cause of the loss, the assured has failed to prove his case."
"I think it would be going too far to describe a collision between the vessel and a submarine, rupturing the shell plating of the vessel, as impossible. But it seems to me to be so improbable that, if I am to accept the plaintiffs' invitation to treat it as the likely cause of the casualty, I (like the plaintiffs' experts) must be satisfied that any other explanation of the casualty can be effectively ruled out."
"They [the underwriters] are not, of course obliged to prove that explanation even on a balance of probabilities, but unless I am satisfied that some degree of probability attaches to it, I am left with no explanation but the owners'."
"In the result, I find myself drawn to conclude that the defendants' wear and tear explanation must on the evidence be effectively ruled out. That leaves me with the choice between the owners' submarine hypothesis and the possibility that the casualty occurred as a result of wear and tear but by a mechanism which remains in doubt."
"how often have I said to you that, when you have eliminated the impossible, whatever remains, however improbable, must be the truth?"
"In such a situation there is no doubt that the learned judge could have held that he was not satisfied with either explanation, but in the light of his specific reference to this possibility in the second numbered paragraph of his exposition of the law (p. 244 left hand column), I cannot believe that he overlooked it."
"I would not have been surprised if, in all the circumstances of this case, the learned judge had concluded that he just did not know what had caused the sinking and that therefore the owners failed. The argument that one can infer from his judgment that he wrongly felt that he had to come down on one side or the other, and that the 'don't know' finding was not open to him, is in my view an attractive one. However, as Sir John Donaldson M.R., has also mentioned, the judge specifically referred to the dictum of Scrutton L.J. in La Compania Martiartu v. The Corporation of the Royal Exchange Assurance [l923] K.B. 650 , 657….
