Questão jurídica principal
Whether the cantonal court violated the binding effect of the Federal Supreme Court's remittal decision by its recalculation of cost coverage.
Decisão extraída
The cantonal court remained within the scope of the remittal; only its plausibility check calculation was inconsistent with the remittal instructions.
Fundamentação extraída
The remittal left the court some discretion to reassess the figures and consider additional objections. There was no binding prohibition against further adjustments beyond the specific correction ordered earlier.
