Kernrechtsfrage
Whether the parity commission had standing to sue for the contractual penalty and costs after the collective agreement was terminated or during a gap in validity.
Extrahierter Entscheid
The commission could continue the proceedings; its mandate was functionally linked to enforcing the agreement and did not lapse with a temporary contractual gap.
Extrahierte Begründung
Its task is to enforce the collective agreement for the relevant period, and the power of attorney must be understood functionally, not as expiring before pending proceedings end.
