Questione giuridica chiave
Whether the appeal against the partial arbitral award was admissible despite non-payment of the advance on costs.
Decisione estratta
The appeal could not be entered into because the appellant failed to pay the court advance even after the additional deadline under Art. 62(3) BGG.
Motivazione estratta
After the advance was ordered and a final extension warned of non-entry, the appellant still did not pay; non-entry therefore followed under Art. 62(3) BGG.
