Kernrechtsfrage
Whether the authorization to open the investigation could be challenged in the seal-lifting proceedings
Extrahierter Entscheid
No separate remedy exists against the opening authorization; the objection is therefore inadmissible in this procedure.
Extrahierte Begründung
The chamber may review only the admissibility of the paper search under Art. 50(3) DPA, not the opening of the investigation itself. The legal system provides no avenue to attack the opening authorization as such.
