Kernrechtsfrage
Whether the respondent owed extra compensation for landfill volume added in a later expansion project.
Extrahierter Entscheid
No. The original contract covered only the approved volume of 205,811 m³, and the later additional fill was tied to a separate project undertaken by J. AG, not to the respondent.
Extrahierte Begründung
The court accepted that the original agreement set a lump-sum fee based on the approved project volume, already paid in full. For the later expansion, the respondent was not involved, did not receive payment, and the documents showed J. AG as the applicant and contracting party for the additional works.
