Key legal question
Whether the cantonal decision could be challenged by administrative law appeal or only by constitutional complaint
Extracted holding
The decision was based on cantonal criminal procedure law and not on federal public law; administrative law appeal was unavailable, so only constitutional complaint lay.
Extracted reasoning
A decision on private-plaintiff status under Art. 47 StrV is a cantonal procedural matter; references to federal criminal statutes or the UWG do not make it a federal public-law decision.
