Question juridique clé
Whether the recusal request against the prosecutor was filed without delay under Art. 58 CPP.
Solution extraite
The request was late because the alleged grounds were already known in early February 2013, yet no recusal was sought until 8 April 2013.
Motifs extraits
A party must seek recusal immediately upon learning the ground. The appellant had already raised the same concerns in February 2013 and could not wait for later procedural developments to invoke them.
