Kernrechtsfrage
Whether the minor alcohol test purchase constituted covert investigation under former aBVE and thus required its conditions to be met for evidentiary use.
Extrahierter Entscheid
Yes. Even brief, isolated test purchases by a non-recognizable police-related actor are covert investigation when used for criminal prosecution.
Extrahierte Begründung
What matters is that the suspect is deceived because the contacting person is not recognizable as an official. The degree of deception or intrusion is not decisive; active, targeted contact with the suspect suffices.
