Key legal question
Whether the prosecutor correctly issued a non-entry decision under Art. 310 StPO
Extracted holding
Yes. The file contained no concrete indications of a criminally relevant act by B.___ or any other dentist, so the statutory conditions for a non-entry decision were met.
Extracted reasoning
Under in dubio pro duriore, non-entry is only permissible where criminality is clearly absent. Here, the allegations and file did not provide any evidence beyond dissatisfaction with dental treatment; ordinary unsuccessful or undesired treatment does not itself establish a criminal offence.
