Kernrechtsfrage
Whether the plaintiffs were entitled to additional remuneration despite a lump-sum contract because the actual clearing quantities exceeded the tender estimates.
Extrahierter Entscheid
No. The court held that the contract was concluded as a lump-sum agreement and that no enforceable agreement to adjust the price for quantity deviations had been proven.
Extrahierte Begründung
The cantonal findings bound the Federal Court: the State had tendered a specific surface area to be cleared, not a guaranteed quantity of timber. The alleged later adjustment agreement of 25 April 1997 was neither sufficiently substantiated nor shown to have been approved. The plaintiffs' arguments amounted largely to an inadmissible attack on evidence appraisal.
