Kernrechtsfrage
Whether the appellant's business is subject to the FAR collective labor agreement
Extrahierter Entscheid
The record was insufficient to determine whether the company's predominant activity was construction work or landscaping work; the case had to be remitted for factual clarification and a new decision.
Extrahierte Begründung
For mixed businesses, the decisive factor is the activity giving the business its character. The lower court failed to make findings on this decisive point and relied too heavily on the trade register entry, LMV subordination, and a tariff-unity argument, none of which was decisive for FAR subordination.
