Key legal question
Whether the complainant had standing to appeal the classing decision based on civil claims.
Extracted holding
Standing existed only for the Forex-related allegations where a concrete loss could not be excluded; it was denied for the confidentiality and data-deletion allegations because no sufficiently concrete civil damage was shown.
Extracted reasoning
A private complainant must explain the civil claims affected by the decision. Mere assertions that damage is obvious are insufficient, but a possible loss from the Forex transactions was sufficiently plausible at the admissibility stage.
