Question juridique clé
Whether the investigating judge had to be recused for alleged bias and procedural passivity.
Solution extraite
The recusal request was unfounded because the complaints mainly concerned reviewable procedural decisions and did not show concrete partiality or serious repeated misconduct.
Motifs extraits
Under the constitutional guarantee of an impartial procedure, errors or delays in conduct of the investigation are not enough; the proper remedy was to challenge the judge's decisions before the Chamber of Accusation.
