Washington state constitution
Article I
Section 35

Upon notifying the prosecuting attorney, a victim of a crime charged as a felony shall have the right to be informed of and, subject to the discretion of the individual presiding over the trial or court proceedings, attend trial and all other court proceedings the defendant has the right to attend, and to make a statement at sentencing and at any proceeding where the defendant's release is considered, subject to the same rules of procedure which govern the defendant's rights. In the event the victim is deceased, incompetent, a minor, or otherwise unavailable, the prosecuting attorney may identify a representative to appear to exercise the victim's rights. This provision shall not constitute a basis for error in favor of a defendant in a criminal proceeding nor a basis for providing a victim or the victim's representative with court appointed counsel.
