Questão jurídica principal
Whether the untranslated diplomatic notes and late supplemental documents made the extradition request inadmissible.
Decisão extraída
No. The request could be considered because the supporting materials were translated, the appellant understood the notes, and late supplements could be taken into account.
Fundamentação extraída
The treaty goal of mutual assistance should not fail because of formal defects. The formal request and core documents arrived on time; the later guarantee letter was a permissible supplement under the applicable rules.
