Wash. R. Evid. 103

(a) Effect of Erroneous Ruling. Error may not be predicated upon a ruling which admits

or excludes evidence unless a substantial right of the party is affected, and

(1) Objection. In case the ruling is one admitting evidence, a timely objection or motion to

strike is made, stating the specific ground of objection, if the specific ground was not apparent

from the context; or

(2) Offer of Proof. In case the ruling is one excluding evidence, the substance of the

evidence was made known to the court by offer or was apparent from the context within which

questions were asked.

(b) Record of Offer and Ruling. The court may add any other or further statement which

shows the character of the evidence, the form in which it was offered, the objection made, and

the ruling thereon. The court may direct the making of an offer in question and answer form.

(c) Hearing of Jury. In jury cases, proceedings shall be conducted, to the extent

practicable, so as to prevent inadmissible evidence from being suggested to the jury by any

means, such as making statements or offers of proof or asking questions in the hearing of the

jury.

(d) Errors Raised for the First Time on Review. [Reserved--See RAP 2.5(a).]
