Question juridique clé
Whether the appeal against the interlocutory decision on the expert's recusal was admissible and well founded.
Solution extraite
The challenge to the expert was unfounded because prior involvement and an earlier unfavorable opinion did not, by themselves, show objective bias.
Motifs extraits
A medical expert is not already biased merely because he previously examined the person, even if his earlier conclusions were unfavorable. The statements in the first report did not objectively create an appearance of prejudice.
