"'Unjust' I regard as directed primarily to the risk of prejudice to the accused in the conduct of the trial itself, 'oppressive' as directed to hardship to the accused resulting from changes in his circumstances that have occurred during the period to be taken into consideration; but there is room for overlapping, and between them they would cover all cases where to return him would not be fair. Delay in the commencement of conduct of extradition proceedings which is brought about by the accused himself by fleeing the country, concealing his whereabouts or evading arrest cannot, in my view, be relied upon as a ground for holding it to be either unjust or oppressive to return him. Any difficulties that he may encounter in the conduct of his defence in consequence of the delay due to such causes are of his own choice and making. Save in the most exceptional circumstances it would be neither unjust nor oppressive that he should be required to accept them."
"This places the original issues very nearly at large before us, but with the obvious restrictions, first, that this court must consider the District Judge's reasons with great care in order to decide whether it differs from her and, secondly, that her fact-findings, at least where she has heard evidence, should ordinarily be respected in their entirety."
