Kernrechtsfrage
Whether the cantonal court arbitrarily found that the tax adviser was mandated by both the donor and the respondent.
Extrahierter Entscheid
No arbitrariness was shown; the inference of an implied agreement with the respondent was tenable.
Extrahierte Begründung
The Federal Court held that payment by the father and initial contact in his name did not exclude a tacit mandate between the adviser and the respondent. Meetings with the respondent and activity in her interest allowed the cantonal court to infer a mutual understanding; such factual appreciation was not manifestly untenable.
