Key legal question
Whether the judge had to be recused because he and a Credit Suisse administrator shared roles in the Confrérie des vignerons and the officers' association.
Extracted holding
No. Shared membership in cultural or professional associations, without concrete facts showing special closeness, dependence, or bias, does not objectively justify doubt as to impartiality.
Extracted reasoning
The court held that such organizations create collegial relations and social prestige, but not presumed intense friendship or hidden ties. The appellant alleged no concrete circumstances beyond common institutional affiliations, and the same reasoning applied to the officers' association.
