Evidence of qualifying mental disorder admissible as to intent

Evidence that the actor suffered from a qualifying mental disorder is admissible whenever it is relevant to the issue of whether the actor did or did not have the intent which is an element of the crime. [1971 c.743 §37; 2017 c.634 §4]

Notes of Decisions

Although defendant was entitled under this sec­tion to introduce evidence of partial responsibility, court was not re­quired to instruct jury on partial responsibility doctrine where general instruc­tion was given on ele­ments of crime charged. State v. Booth, 30 Or App 351, 567 P2d 559 (1977), aff’d 284 Or 615, 588 P2d 614 (1978)

Instruc­tion concerning de­fense of mental disease or defect, which had effect of placing burden of proof of entire de­fense on defendant, was erroneous. State v. Umscheid, 31 Or App 1249, 572 P2d 362 (1977)

The defendant raising the de­fense of mental disease or defect was not entitled to a bifurcated trial, with separate factfinders on the issues of guilt and responsibility, in order to preserve his privilege against self-incrimina­tion and right to a fair trial. State ex rel Johnson v. Dale, 277 Or 359, 560 P2d 650 (1977)

Under this sec­tion, partial responsibility de­fense is available whether or not crime charged includes lesser of­fense; if lesser of­fense is available, successful partial responsibility de­fense may reduce crime to lesser of­fense; if there is no lesser included of­fense, successful partial responsibility de­fense will result in acquittal. State v. Booth, 284 Or 615, 588 P2d 614 (1978)

Court did not err in excluding “partial responsibility” evidence, under this sec­tion, when evidence was in fact admitted to prove insanity. State v. Francis, 284 Or 621, 588 P2d 611 (1978)

Where defendant, convicted of mur­der, requested instruc­tion on “partial responsibility” de­fense as to ORS 163.118 (Manslaughter in the first degree) or 163.125 (Manslaughter in the second degree) (manslaughter), proof of intent was not re­quired for con­vic­­tion of lesser included manslaughter of­fenses and requested instruc­tion was properly refused. State v. Armstrong, 38 Or App 219, 589 P2d 1174 (1979), Sup Ct review denied

Partial responsibility de­fense is available for crimes having “knowing” mental state as re­quired ele­ment. State v. Smith, 154 Or App 37, 960 P2d 877 (1998)

“Intent which is an ele­ment of the crime” includes mental state of recklessness. State v. Nebert, 244 Or App 80, 260 P3d 559 (2011)

For purposes of this sec­tion, transitory, episodic, drug-induced psychosis is per­sonality disorder, not mental disease or defect. State v. Folks, 290 Or App 94, 414 P3d 468 (2018)

Notes of Decisions

A juvenile court adjudica­tion of whether or not a child committed acts which would be a crim­i­nal viola­tion if committed by an adult must necessarily include an adjudica­tion of all af­firm­a­tive de­fenses that would be available to an adult being tried for the same crim­i­nal viola­tion.
