Kernrechtsfrage
Whether telecom providers may appeal the Special Tasks Service orders by challenging the legality of the underlying surveillance orders.
Extrahierter Entscheid
No. The providers may contest only technical or organizational aspects of execution, not the legality or proportionality of the approved surveillance itself.
Extrahierte Begründung
The statute assigns the legality review exclusively to the authority that authorizes surveillance. The Special Tasks Service and providers act only as executors; no gap in the law justifies extending standing to attack the surveillance order's validity.
