Kernrechtsfrage
Whether the lawyer had standing to challenge the cantonal award of party costs to the client.
Extrahierter Entscheid
The lawyer lacked standing to contest the allocation and amount of the client's party costs; only the client could do so.
Extrahierte Begründung
A lawyer's own protected interest does not extend to increasing the client's party compensation, since the fee relationship between client and lawyer is legally separate and such standing would create a conflict of interest.
