Whether the appeal against the interlocutory ruling on T.________'s civil-party standing was admissible.
The ruling could not be challenged by immediate appeal because it was a procedural/interlocutory decision that caused no irreparable harm and did not terminate the proceedings.
Under Arts. 339 and 393 CPP, such questions are generally decided immediately by the trial court, but interlocutory rulings of first-instance courts are not separately appealable unless they cause irreparable prejudice or end the case. Those conditions were not met here.
