Questione giuridica chiave
Whether the sealed bank documents should be unsealed for examination in mutual legal assistance proceedings.
Decisione estratta
The documents may be unsealed because they can be useful for the foreign investigation; only the admissibility of the search is decided here.
Motivazione estratta
Under Art. 9 IRSG and Art. 69 BStP, unsealing is permissible where the documents may be useful for the foreign investigation. The envelopes contained material that could clarify origin, route, payments, and possible criminal association, so the usefulness threshold was met despite procedural irregularities in sealing.
