Questão jurídica principal
Whether the appeal against the incidental order was admissible due to immediate and irreparable prejudice from foreign participation in interviews.
Decisão extraída
The appeal was admissible only to the limited extent that the alleged prejudice had to be examined; the court found no sufficient immediate and irreparable prejudice shown beyond that limited review.
Fundamentação extraída
Foreign participation is not automatically harmful. Immediate prejudice exists only if persons from the requesting state gain access to secret matters before the Swiss authority decides on transmission, and the appellants did not make this plausible for their own legally protected sphere.
