Kernrechtsfrage
Whether the appellants had standing to challenge the pretrial order on expert questions after waiving the expert report.
Extrahierter Entscheid
They no longer had a practical and current interest because the expert examination had been abandoned, so the complaint against that order was not admissible.
Extrahierte Begründung
Under Art. 88 OG, a public-law appeal requires a practical and current interest; once the appellants renounced the expert report, even an unconstitutional order could no longer be remedied.
