Key legal question
Whether the Portuguese request was abusive because the requesting prosecutor allegedly lacked competence to seek bank records.
Extracted holding
The request was not abusive; Swiss authorities do not review the requesting authority's competence unless manifest incompetence makes the request abusive.
Extracted reasoning
The Portuguese declaration under the mutual assistance convention allowed the public ministry to act as judicial authority. Any internal Portuguese procedural rule did not bar the request, and the additional Swiss certification requirement was not opposable under the convention.
