If the party who made the initial accusation no longer wants to see you prosecuted or cooperate with the prosecution, they may file an affidavit of non-prosecution with the district attorney’s office. However, just because the alleged victim no longer wishes to pursue charges does not mean that your case will be automatically dismissed. The district attorney has the final say over whether to withdraw criminal charges. The DA’s office may wish to continue your prosecution, even after your alleged victim has withdrawn his or her cooperation, if the prosecution believes they have sufficient evidence of your guilt, even without the victim’s testimony, to obtain a conviction.
