Questione giuridica chiave
Whether the project manager had authority to conclude cleaning contracts binding the developer
Decisione estratta
No. The total contractor agreements, AVB, treuhand contract, and written work contracts did not establish authority to conclude the disputed cleaning contracts.
Motivazione estratta
The AVB limited the project manager to execution-related powers; contract conclusion remained with the developer. The treuhand contract only gave monitoring, control, and reporting duties. Signed work contracts and use of the project manager's letterhead did not create authority.
