Key legal question
Whether allegedly injured complainants have standing to challenge the closure of a criminal investigation by constitutional appeal.
Extracted holding
Yes. As allegedly injured parties, they have a direct and personal interest because the closure prevents them from pursuing civil claims by adhesion in the criminal proceedings.
Extracted reasoning
Even if Bernese procedure grants the complainants no formal party rights in the investigation, they are sufficiently affected by the decision in light of their concrete civil interests and their loss of the possibility to join the criminal case as civil parties.
