Key legal question
Whether the complainant had standing under Art. 81 para. 1 BGG to challenge the cantonal decision
Extracted holding
He lacked standing because he was neither a private prosecutor nor an injured party with a legally relevant impairment; as merely an aggrieved person, he could not appeal.
Extracted reasoning
The alleged acts caused no significant interference with bodily integrity. The appellant stated that he treated the forehead injury himself and did not consult a doctor, so victim status under the Victim Support Act was not met.
