The current programs in this unit include:

District Court Unit

Minor in Possession of Alcohol (MIP Diversion Program)

This office has implemented a diversion program for those who commit the offence of Minor in Possession of Alcohol (MIP). This program is offered to individuals between the ages of 18 and 20 who have been arrested for the crime of Minor in Possession of Alcohol and who face being charged in adult criminal court.

The program works as follows:

When we receive an MIP case from the police, we send the individual a letter instructing them to contact and sign up with a State Certified Alcohol and Drug Information School (A.D.I.S). The individual is given a period of 90 days to sign up and complete an A.D.I.S. class. When an individual completes A.D.I.S. he/she must then send a copy of their completion certificate to the Prosecutor's mailing address (see below). It is the responsibility of the individual to ensure that the Prosecutor receives proof of completion. Once class completion has been verified, no criminal charges will be filed in King County's District Court and the case will be closed.

However, if for any reason the individual declines to enroll in the program or doesn't complete their A.D.I.S class, their case will be reviewed for criminal prosecution in District Court and charges will likely be filed. This could result in a conviction for MIP, a crime that carries a maximum penalty of one year in jail and a $5,000 fine.

This is a great opportunity for individuals ages 18-20 to avoid criminal prosecution for this charge.

Send copy of completion certificate with a copy of your MIP diversion letter to:

King County Prosecuting Attorney
W554 King County Courthouse
516 Third Avenue
Seattle, WA 98104-2362
Attention:District Court Unit

Juveniles under the age of 18 who have been arrested for MIP should contact juvenile court, 206-296-9025, regarding juvenile diversion programs.

Involuntary Treatment Act Unit 

The Involuntary Treatment Act (ITA) Unit handles behavioral health (mental health and substance use disorder) commitment cases. Persons with behavioral health illness who present a risk to themselves or others may be detained involuntarily and placed into a local in-patient mental health evaluation and treatment facility or secure withdrawal management and stabilization facility. The set of laws which allows this is called the Involuntary Treatment Act. The initial detention is for up to 120 hours. If the treating facility believes further in-patient treatment is necessary, the facility petitions the court for up to 14 days of involuntary treatment. The patient can contest the need for the detention and treatment, and is entitled to a full hearing governed by the rules of evidence. By statute, the Prosecuting Attorney's Office represents the treatment facility seeking longer involuntary treatment. These proceedings are considered to be civil, rather than criminal, proceedings.

The ITA hearings are conducted via video over Zoom.

ITA Court should not be confused with criminal mental health courts, which are run by either the King County District Court or Seattle Municipal Court and are part of the criminal justice system.
