Wash. Crim. R. Cts. Ltd. Juris. 4.3

(a) Joinder of Offenses. Two or more offenses may be joined in one charging document,

with each offense stated in a separate count, when the offenses:

(1) Are of the same or similar character, even if not part of a single scheme or plan; or

(2) Are based on the same conduct or on a series of acts connected together or constituting

parts of a single scheme or plan. The number of offenses in one charging document may be

governed by local court rule.

(b) Joinder of Defendants. Unless otherwise provided by local court rule, two or more

defendants may be joined in the same charging document:

(1) When each of the defendants is charged with accountability for each offense included;

(2) When each of the defendants is charged with conspiracy and one or more of the

defendants is also charged with one or more offenses alleged to be in furtherance of the

conspiracy; or

(3) When, even if conspiracy is not charged and all of the defendants are not charged in

each count, it is alleged that the several offenses charged:

(i) were part of a common scheme or plan; or

(ii) were so closely connected in respect to time, place and occasion that it would be

difficult to separate proof of one charge from proof of the others. Such defendants may be

charged in one or more counts together or separately and it shall not be necessary to charge all

defendants in each count.

(c) Improper Joinder. Improper joinder of offenses or defendants shall not preclude

subsequent prosecution on the same charge for the charge or defendant improperly joined.
