“In the case of the United States and part 2 offences, the analogue of the warrant is the request, whether or not it includes more than is required for prosecution of the offence indicated in the Part 2 territory, for example, here, the ingredient of dishonesty to garnish the Sherman Act offence.”
“A narrative of events prior in date to the conduct relied on will not be objectionable if it is included merely to set the scene …. Information of that kind is relevant and admissible to enable inferences to be drawn as to the nature of the offence constituted by the conduct for which extradition is sought. But it is the conduct for which extradition is sought, not any narrative that may be included in the Part 1 warrant simply by way of background, that must satisfy the test of double criminality.”
