Key legal question
Whether the criminal complainant had standing to file a constitutional appeal against non-opening/termination of the criminal investigation.
Extracted holding
He had no standing because a complainant or injured person has only a factual, not a legally protected, direct interest in prosecution and punishment.
Extracted reasoning
The criminal claim belongs to the state. Only procedural rights, if violated in a form amounting to denial of justice, can be invoked; no such properly reasoned procedural-rights violation was shown.
