WA state DUI law, revocation of deferred prosecution

One other bit of advice: if you don't have it, get a copy of the deferred prosecution agreement you signed. It has all the specifics to answer this question. In short, a new offense MAY result in revocation; failure to comply with treatment MAY result in revocation. Failure to do a VIP class or pay the fine timely (or restitution, if ordered) or to meet with probation MAY result in revocation. All would surely result in a review hearing to determine whether your DP should be revoked. Failure to attend a court hearing on this or any other case could also lead to revocation. Again, all the answers to your question are in that agreement. If you lost your copy/can't find it, you can request a new copy from the court clerk.

If i understand the question: you are asking how can a DUI Deferred Prosecution (DP) be revoked? the answer is fairly simple. A conviction for a similar type of offense after being accepted on the DP or becoming so non-compliant with your treatment plan that you are unable to finish the program within the time required under the DP statute RCW 10.05. A similar offense is a new DUI, and most Judges will also consider a Reckless Driving or Negligent Driving reduced from the original charge of DUI a similar offense. If you are wondering how this happens it is because it is what a person agrees to at the time they ask (Petition) the Court to grant them a DP. in short you make an agrement with the court to remove you from the DP if new convictions occur. Procedurally speaking, the probation department that monitors your DP learns of the new charge by running your record and they notify the Court and the Court issues a summons for you to appear and answer the allegation of new charges or new conviction. It is extremely important to have a lawyer with you at these hearings because they are complicated and there is much as risk if a person is removed from the program. Preferably the lawyer handeling your new charges will also handle the DP revocation hearing.

Mr. Rands is absolutely right. There are violations that require mandatory revocation and violations that give the court discretion about whether revocation is appropriate. A new similar criminal charge, like a DUI or negligent driving, is a mandatory revocation. A less serious violation, like a non-driving relapse or a non-related criminal case, may or may not result in revocation. You should be able to contact the attorney who assisted you in the original case about the risk of revocation. If not, talk to a new lawyer; but do it quickly.
