Kernrechtsfrage
Whether the respondent was obliged to conclude an engineering/faculty planner contract with the appellant's proposed consortium.
Extrahierter Entscheid
No. Any prior-contract right to conclude the main contract belonged, if at all, to the appellant as an individual team member, not to a different consortium of three engineering firms.
Extrahierte Begründung
The person of the contracting party mattered in this kind of architectural/engineering mandate. The offer was made on behalf of a consortium, which changed the content of the obligation and exceeded what the respondent had undertaken.
