Oregon law provides that a person will be disqualified from participating in the DUII Diversion Program if the person was convicted of a DUII or participated in a DUII Diversion Program (or a similar program) within the 15 years prior to the current DUII arrest. Therefore, whether you qualify will depend on the type of Diversion you had previously.

The case law and statutes are a little more convoluted than just suggesting that any non-DUI diversion would still put you in the clear. I would not bring this up in court - I would only speak in private with a DUII attorney about it before approaching your case. First, you need to have any serious criminal matter (even diversion is serious - it costs more than $1500 - requires you to plead guilty - put an IID in your vehicle - undergo treatment, etc...) reviewed by an expert in the field you are charged with. There are so many technical defenses and suppression arguments in the field of DUII that conferences could last weeks on the topic. It is important to have a DUII reviewed to make sure diversion is your best option.
Second, you might be able to avoid having to reveal the prior diversion if you are careful in approaching the court. A skilled attorney can let you know whether it is something that should be revealed or kept quiet. Best of luck to you.
You may or may not be eligible for DUI diversion--it depends on the facts of your case and what you specifically did for your diversion for your Harassment. An experienced DUI defense attorney can help you understand your options and help you choose the best option for you.
