Key legal question
Whether the Austrian request was too contradictory, incomplete, or based on impermissible fishing expedition.
Extracted holding
The request was not immediately undermined by obvious errors, gaps, or contradictions; the requested facts were binding for the Swiss authority.
Extracted reasoning
Swiss assistance authorities do not decide truth or guilt and follow the request unless defects are immediately self-evident. The objections concerned details that did not destroy the factual narrative.
