Questão jurídica principal
Whether the complainant had standing to challenge the non-prosecution decision despite lacking direct civil-claim effects.
Decisão extraída
He lacked standing because cantonal law provides state liability and excludes claims against the official personally.
Fundamentação extraída
The challenged decision could not affect any civil claims against the prosecutor; under Zug law, only the state is liable and no claim lies against the official who caused the damage.
