Kernrechtsfrage
Whether a party that fails to pay the advance for an expert or witness may be barred from asking questions
Extrahierter Entscheid
No. It is impermissible to forbid the party from questioning an expert or witness because of non-payment of the cost advance.
Extrahierte Begründung
The court distinguished between the right to ask questions and the consequences of not advancing costs. Non-payment does not justify restricting questioning.
