After you are arraigned, your case is assigned to a judge. This is a critical time. In some cases, it may be advisable to exercise an affidavit of prejudice to have your case reassigned to a different judge. Every defendant is entitled to one affidavit of prejudice but the affidavit must be exercised in a timely fashion.
The pretrial conference is an opportunity for the prosecutor and the defense attorney to discuss the case and attempt to resolve the case. Your appearance at this hearing is mandatory unless it is properly waived. During the course of a DUI case, there may be multiple pretrial conferences.
