Kernrechtsfrage
Whether H.________'s 22 January 2014 letter constituted a valid appeal against the joinder order.
Extrahierter Entscheid
The court held that the letter was not an appeal because H.________ failed to confirm his intention to appeal and to regularize the filing within the time limit.
Extrahierte Begründung
After being invited to clarify and complete the filing, H.________ remained silent. This silence amounted to an implied waiver of appeal, so the court took formal notice that the letter was not a remedy.
