Questão jurídica principal
Whether the prosecutor had to recuse himself because of alleged bias and whether the recusal request was timely.
Decisão extraída
The recusal request was correctly rejected: the later letter did not establish a recusal ground, and the earlier circumstances were raised too late.
Fundamentação extraída
Recusal motions must be filed without delay once the relevant facts are known. Earlier known facts may only be combined with later ones if the later fact is the last element completing the overall appearance of bias. Here, the appellant could not credibly show that the prosecutor's letter contained falsehoods, and the prior relationship-based concerns had long been known and were already time-barred.
