“Norris: The 'Conduct Test' 10.Three principles from extradition case-law featured in the arguments. First, there is the ‘conduct test’ as recognised in Norris v USA[2008] UKHL 16 [2008] 1 AC 920 . For the purposes of satisfying s.137 dual criminality (§65): The court [is] required to make the comparison and to look for the necessary correspondence … between the conduct alleged against the accused abroad and an offence here. This is ‘the conduct test’, with (§91): the conduct … being that described in the documents constituting the request … Assange: The 'Irresistible Inference' Test 11. Secondly, there is the ‘irresistible inference’ test, recognised in Assange v Sweden[2011] EWHC 2849 (Admin) at §57. Where a necessary element (or ingredient) of the UK offence is being ‘inferred from the description of the conduct set out in the [Request]’, it may be necessary for ‘the facts set out … to impel the inference’, as ‘the only reasonable inference to be drawn from the facts alleged’. The Court gave an example: a description in the particulars provided in the Request of a ‘use of force or coercion’ would carry – as an irresistible inference – the absence of the defendant's reasonable belief in consent. Cleveland: The 'Missing Ingredient' Test 12. Thirdly, there is the 'missing ingredient' test, to identify when the Assange ‘irresistible inference’ test is applicable. This comes from Cleveland v United States[2019] EWHC 619 (Admin) . Cleveland decided that the irresistible inference test is applicable only where ‘the argument is raised that the offence alleged in the foreign state lacks an ingredient essential to criminality in this jurisdiction’ (§63), and ‘an essential ingredient under [UK] law is absent from the alleged foreign offence’ (§61). Where that is not the case and the argument is simply that the ‘particulars of conduct supplied in the warrant or request do not address an ingredient of an equivalent English offence’, the test is different: whether ‘an inference can properly be drawn’ from information in the Request (§61); or whether that information is ‘incapable of supporting any such inference’ (§64)”
