“(3) There are specialty arrangements with a category 2 territory if (and only if) under the law of that territory or arrangements made between it and the United Kingdom a person who is extradited to the territory from the United Kingdom may be dealt with in the territory for an offence committed before his extradition only if- (a) the offence is one falling within subsection (4), or (b) he is first given an opportunity to leave the territory. (4) The offences are – (a) the offence in respect of which the person is extradited; (b) an extradition offence disclosed by the same facts as that offence, other than one in respect of which a sentence of death could be imposed; (c) an extradition offence in respect of which the Secretary of State consents to the person being dealt with; (d) an offence in respect of which the person waives the right that he would have (but for this paragraph) not to be dealt with for the offence.” (a) the offence in respect of which the person is extradited; (b) an extradition offence disclosed by the same facts as that offence, other than one in respect of which a sentence of death could be imposed; (c) an extradition offence in respect of which the Secretary of State consents to the person being dealt with; (d) an offence in respect of which the person waives the right that he would have (but for this paragraph) not to be dealt with for the offence.”
“These cases suggest that the doctrine of specialty is concerned primarily with prosecution for different substantive offenses than those for which consent has been given, and not prosecution for additional or separate counts of the same offense. The appropriate test for a violation of specialty ‘is whether the extraditing country would consider the acts for which the defendant was prosecuted as independent from those for which he was extradited’. Id. at 1435 (citations omitted). Moreover, we do not believe Mexico would consider the acts for which Aaron was prosecuted to be independent from those for which he was extradited.”
“Although extradition agreements and the specialty doctrine undeniably control the United States courts’ jurisdiction over foreign defendants such as Gallo, these international principles of law cannot be “construed to permit foreign intrusion into the evidentiary or procedural rules of the requisitioning state.””
