Question juridique clé
Whether the two psychiatric experts had to be recused for apparent bias due to their affiliation with CHUV and a prior case involving Dr. D.
Solution extraite
No objectively ascertainable circumstance created a sufficient appearance of bias; mere affiliation with CHUV and speculative institutional hostility were insufficient.
Motifs extraits
Recusal under Art. 56 lit. f CPP requires objectively established circumstances giving rise to an appearance of partiality. The experts were not asked to assess Dr. D.'s conduct directly, but to answer specific questions in the mandate, and any alleged animosity remained speculative.
