Questão jurídica principal
Whether the Obergericht violated the appellant's right to be heard by not taking requested evidence on the company's role as employer/operator of the restaurant.
Decisão extraída
No violation occurred. The courts reasonably rejected the additional evidence in anticipatory appraisal because the existing evidence already allowed them to decide that the company operated the business and was bound by the contract.
Fundamentação extraída
The lower courts addressed the evidentiary request, referred to the first instance's reasoning, and could omit further clarification since additional records from tax and pension authorities would not alter the established evidentiary result.
