State v. Wiltse, 559 P.3d 380

Defendant Matthew Ryan Wiltse was convicted of third-degree assault in Oregon for injuring RR, after an altercation involving a metal pole and a knife.
The key disputed element at trial was whether RR’s injuries (fractures and a facial scar) amounted to "serious physical injury," specifically "protracted disfigurement."
The trial court adopted a special jury instruction (requested by the prosecution) stating that "a scar on the scalp, visible five months after the injury, qualifies as 'protracted disfigurement.'"
Defendant did not object to the instruction at trial and later argued, on appeal, that it was an impermissible comment on the evidence, violating ORCP 59 E.
The Oregon Court of Appeals agreed the instruction was an improper comment but held it did not qualify for "plain error" review, as there was a possibility the defendant consented or strategically did not object.
The Oregon Supreme Court reviewed whether this was a proper application of the plain error doctrine and, while finding an error, ultimately affirmed the conviction because the error was not grave given the record.

Issue	Wiltse's Argument	State's Argument	Held
Was the special jury instruction a prohibited comment on the evidence?	The instruction indicated specific evidence satisfied an element, violating ORCP 59 E.	The instruction was justified based on prior precedent and not a prohibited comment.	The instruction improperly commented on the evidence.
Does such an error qualify as "plain error" reviewable on appeal if not objected to at trial?	Yes; error apparent from the instruction itself, regardless of defense consent or strategy.	No; error not "apparent on the record" because defendant might have agreed or not objected strategically.	Yes; error can be determined from the instruction’s content, not party conduct.
Should the appellate court exercise its discretion to reverse for this plain error?	Yes, because the comment usurped the jury’s fact-finding role.	No; error was not grave and defendant did not dispute the nature of the injuries.	No; under Ailes factors, error was not grave, so no reversal.
Do parties’ actions (agreement or silence) affect whether an instructional error is apparent on the record?	No; court's legal duties on instructions are independent of party actions.	Yes; possible agreement precludes error from being "apparent" under plain error doctrine.	No; content alone controls, but agreement/silence may weigh against discretionary reversal.
