VFJ is a wonderful program, but they can not act as an attorney on behalf of the victims. They can not file motions, be a party to the case, or argue points in court. OVR can. They are a free ATTORNEY agency provided to victims just like the public defender/OPA is for the defendant. Without OVR, the victim has limited help, with agencies that can only guide them through the process. These agencies can not do what OVR does as they are not legally set up to. OVR is more than a support office, they are legal representation with legal attorneys.
