W.R.E. 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 appears of record, 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. It 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) Plain error. — Nothing in this rule precludes taking notice of plain errors

affecting substantial rights although they were not brought to the attention of the

court.
