STATE OF OREGON, Respondent on Review, v. ERIK JOHN MEISER, Petitioner on Review. (CC CR1201547) (CA A166534) (SC S068327) 506 P3d 402
Defendant, who had been diagnosed with schizophrenia and antisocial per- sonality disorder, asserted a defense of guilty except for insanity (GEI) to murder and other charges. The trial court, sitting as factfinder, rejected defendant’s GEI defense as to the murder charge, and the Court of Appeals affirmed, reasoning that the evidence permitted a finding that defendant’s asserted incapacity was at least partly a result of his antisocial personality disorder, and not the result of his schizophrenia alone. Held: ORS 161.295 provides that a co-occurring dis- order that is solely a personality disorder is excluded from the “mental disease or defect” that forms the basis for a GEI defense, but the statute does not require a defendant asserting the GEI defense to prove that a co-occurring personality disorder played no causal role in bringing about the requisite lack of substantial capacity. The decision of the Court of Appeals is reversed in part, and the case is remanded to the Court of Appeals for further proceedings.

FLYNN, J. Defendant, who has been diagnosed with schizo- phrenia and a co-occurring antisocial personality disorder, contends that the trial court and the Court of Appeals erred in its understanding of the evidence required to establish that he was guilty except for insanity (GEI) with respect to charges of murder. GEI is an affirmative defense that requires proof that, “as a result of mental disease or defect,” the defendant “lacks substantial capacity either to appreci- ate the criminality of the conduct or to conform the conduct to the requirements of law.” ORS 161.295(1) (2011), amended by Or Laws 2017, ch 634, § 3.1 But “the terms ‘mental dis- ease or defect’ do not include * * * any abnormality constitut- ing solely a personality disorder.” ORS 161.295(2). The par- ties agree that schizophrenia is a “mental disease or defect” within the meaning of ORS 161.295, and they agree that defendant’s co-occurring antisocial personality disorder is a “personality disorder” within the meaning of the statute. But they disagree about whether ORS 161.295 requires proof that defendant experienced the requisite incapacity solely “as a result of” his schizophrenia, and not in any part as a result of his co-occurring antisocial personality disorder. As explained below, we conclude that the legislature intended to specify that a co-occurring disorder that is solely a per- sonality disorder is excluded from the “mental disease or defect” that forms the basis for a GEI defense, but the leg- islature did not intend to require proof that a co-occurring personality disorder played no causal role in bringing about the requisite lack of substantial capacity. That con- clusion resolves the issue on which we allowed review, but it leaves unresolved additional legal and factual questions
1 The 2011 version of the statute applies in defendant’s case, and we cite that statute without reference to a year in the remainder of this opinion. The legislature amended ORS 161.295 in 2017 by replacing the term “mental disease or defect” with the term “qualifying mental disorder.” Or Laws 2017, ch 634, § 3. The preamble to the 2017 amendments indicates that the legislation intended to replace the term “mental disease or defect,” which “may carry a negative conno- tation,” with an updated term, “while preserving the validity of all previous court decisions interpreting” the prior wording and “without making a substantive change to Oregon law.” Id., preamble. Although we are mindful of the negative connotations of the term “mental disease or defect,” it is the applicable statutory term in this case, and, because it would be confusing to do otherwise, we use it throughout this opinion. 350 State v. Meiser
regarding defendant’s proof of causation and incapacity. We remand the case to the Court of Appeals to address those questions. I. BACKGROUND Defendant, who has been diagnosed with schizo- phrenia and antisocial personality disorder, killed FH during a home-invasion robbery. At the time, defendant was suffering from multiple delusions, including the belief that his children were in danger because “poorer people were being harvested.” Defendant believed that the only way to protect his children was to own property, and he set out to steal $40,000 for a down payment on a “condo.” Defendant first broke into a martial arts studio, looking for a person whom he believed might be a source of money. No one was in the building, but defendant found and stole a samurai sword. After stealing the sword, defendant decided to rob FH and his wife. Defendant later told a detective that he targeted FH and his wife because voices—“these people who follow me constantly”—told him that “the only way” he would “ever get any money is through this course of action.” Defendant waited until he saw FH and his wife leave their house and then entered it to wait for them to return. His plan was to have “a discussion about the ailments of soci- ety” and then have them transfer $40,000 to defendant. He did not plan to harm anyone, but he took a machete from the victims’ workbench to intimidate them. When the vic- tims returned home and found defendant, both victims pan- icked and ran outside. Defendant pursued FH and struck him multiple times in the head with the machete. Defendant then changed clothes nearby, discarded his bloody jeans, and entered the garage of another residence to steal a bicy- cle to help him escape. The state charged defendant with multiple counts of aggravated murder, robbery, and burglary related to the invasion of FH’s home, as well as with second-degree bur- glary counts related to the samurai sword and the bicycle. Defendant was repeatedly found to lack the capacity to stand trial. He spent nearly four years confined at the Oregon Cite as 369 Or 347 (2022) 351
State Hospital before ultimately being found competent to stand trial. Defendant did not dispute that he had commit- ted the criminal acts for which he had been charged, but he asserted the affirmative defense of GEI to all of the charges. See ORS 161.295 (setting out the GEI defense); ORS 161.305 (2011), amended by Or Laws 2017, ch 634, § 5 (specifying that “[m]ental disease or defect constituting insanity under ORS 161.295 is an affirmative defense”). As defined by the legis- lature, that defense required defendant to prove that, “as a result of mental disease or defect at the time of engaging in criminal conduct,” he “lack[ed] substantial capacity either to appreciate the criminality of the conduct or to conform the conduct to the requirements of law.” ORS 161.295(1). But the legislature also specified that “the terms ‘mental disease or defect’ do not include * * * any abnormality constituting solely a personality disorder.” ORS 161.295(2).
Defendant waived his right to trial by jury and tried his case to the court. He offered the testimony of a psycholo- gist and three psychiatrists, all of whom opined that defen- dant was suffering from schizophrenia but recognized that he had a co-occurring diagnosis of antisocial personality disorder. One of the psychiatrists explained that, as a symp- tom of defendant’s schizophrenia, defendant experienced “command auditory hallucinations”—voices that defen- dant believed to be telepathic communications from unseen entities—although defendant did not experience “the kind of overwhelming command auditory hallucinations some other psychotic individuals have.”
Two of the experts addressed the other elements of the GEI defense. Both testified that, at the time of the crimes, defendant lacked substantial capacity to conform his con- duct to the requirements of the law. And both testified that, if not for the psychosis, defendant would not have committed the crimes. One of the experts specifically rejected the sug- gestion that defendant’s “conduct [was] a result of antisocial personality disorder rather than schizophrenia.” The other opined that both of defendant’s conditions were “active” at the time of the murder but that defendant’s psychosis asso- ciated with his schizophrenia “was more the predominant driver of his behaviors.” 352 State v. Meiser
The state offered no contrary expert testimony, but it argued that the expert testimony failed to establish the elements of defendant’s GEI defense. With respect to causation, the state disputed both the sufficiency of defen- dant’s evidence and the applicable legal test. The state did not dispute that schizophrenia is a “mental disease or defect,” but it argued that defendant was required to prove that the requisite incapacity “resulted from [that] mental disease [or defect] and nothing else” and that, unless the court found that incapacity resulted “from solely a mental disease [or defect], the Court may not find the defendant guilty except insane.” The state insisted that defendant could not prove the causation element of his GEI claim. It first argued that defendant’s “choices” were not solely the result of his schizo- phrenia, but “were at least, if not substantially, influenced by his anti-social personality disorder.” Second, the state argued that the court could find that “neither” condition led to defendant’s conduct. At the conclusion of the trial, the court found that defendant was guilty except for insanity with respect to the charges of burglary and robbery of FH’s home and with respect to the earlier burglary of the martial arts studio. But the court found that defendant had not proven the GEI defense with respect to the murder of FH and the subse- quent burglary of the garage. As to that conduct, the court found defendant guilty of murder, as the lesser-included offense of aggravated murder, and of second-degree bur- glary. The court rendered its verdicts without explaining whether it had agreed with the state’s proposal that “as a result of mental disease or defect” required defendant to prove that any incapacity was solely the result of his schizo- phrenia and without identifying the element or elements of the GEI defense that defendant failed to prove with respect to the murder and final burglary charges.2
2 On appeal, defendant assigned error to the trial court’s denial of his verbal request, made after the court announced its verdicts, that the court make “findings of fact and conclusions of law.” The Court of Appeals rejected that assignment of error, reasoning that “defendant’s generalized request did not trigger the trial court’s obligation to address the elements of the GEI defense.” State v. Meiser, 308 Or App 570, 591, 481 P3d 375 (2021) (internal quotation marks omitted). Defendant does not reprise the issue before this court. Cite as 369 Or 347 (2022) 353
Defendant appealed his convictions to the Court of Appeals and assigned error to, among other rulings, the trial court’s rejection of the GEI defense to the murder charge.3 With respect to the GEI defense, defendant insisted that the state had proposed an incorrect legal test when it argued that defendant was required to prove that his incapacity resulted “solely” from defendant’s schizophrenia. Although the trial court had not specified whether it accepted the state’s test, defendant urged the Court of Appeals to conclude that the trial court had accepted the state’s understanding that “as a result of” in ORS 161.295(1) means “solely” as a result of. Under the correct causation test, defendant contended, no reasonable factfinder could fail to find that defendant had proven the elements of his GEI defense. The Court of Appeals affirmed. State v. Meiser, 308 Or App 570, 481 P3d 375 (2021). Because the trial court had not identified the element or elements that, in its assess- ment, defendant had failed to prove, the Court of Appeals reasoned that defendant could establish error only if he established that he was entitled to prevail as a matter of law on each element of the defense. Id. at 578. The court observed that there was no dispute on appeal that defendant had established the first element of the GEI defense: that his schizophrenia qualified as a “mental disease or defect” under the statute. Id. But the court concluded that defen- dant had not established that he was entitled to prevail as a matter of law on the causation element. Id. at 586. The court understood one of its own prior decisions to preclude defendant’s understanding of the causation element. Id. at 581-82 (citing State v. Peverieri, 192 Or App 229, 232-33, 84 P3d 1125, rev den, 337 Or 248 (2004)).4 In this case, the court observed that defendant had not developed an argu- ment for overruling Peverieri and, thus, accepted the state’s proposition “that the requisite incapacity must result from 3 Defendant did not challenge the trial court’s rejection of his GEI defense on the second-degree burglary charge. 4 In Peverieri, the court held that the GEI defense was not available to a defendant who suffered from chronic liver failure because—even assuming the liver condition produced a qualifying “mental disease or defect”—the defen- dant’s state at the time of the criminal activity “was a result of the mental disease or defect and voluntary intoxication.” 192 Or App at 233 (emphasis in original). 354 State v. Meiser
a qualifying mental disease or defect itself, not from a com- bination of qualifying and nonqualifying impairments.” Meiser, 308 Or App at 577, 581-82. Under that test, the court concluded, the evidence permitted the trial court to find that defendant had not proven causation. Id. at 585-86. The court reasoned that “the evidence permitted the factfinder to conclude, at the least, that defendant’s schizophrenia and antisocial per- sonality disorder were both active impairments” and that “[h]is compromised capacity could be found[ ] not to be the result of a mental disease or defect.” Id. (emphasis in origi- nal). The Court of Appeals then discussed the parties’ com- peting arguments regarding whether the evidence required the trial court to find that defendant had been experienc- ing either form of substantial incapacity at the time of the criminal activity, but the court ultimately observed that it was “unnecessary to resolve” those arguments in light of its conclusion that the trial court was permitted to find “that defendant’s asserted incapacity, in whatever form, is not the result of a mental disease or defect.” Id. at 586-88. II. DISCUSSION To prove the statutory defense of GEI, three ele- ments must exist “at the time of engaging in criminal con- duct”: “mental disease or defect”; lack of “substantial capac- ity either to appreciate the criminality of the conduct or to conform the conduct to the requirements of law”; and a causal link between the two. ORS 161.295(1). As explained above, the ultimate dispute between the parties on appeal is whether the evidence at trial established all three elements as a matter of law. We allowed review to address one piece of that dispute, which was dispositive in the Court of Appeals: whether defendant was required to prove that his asserted lack of capacity was solely the result of his schizophrenia and in no part the result of his antisocial personality disorder.5
5 The state contends that we should not reach the question on which we allowed review and should instead affirm based on defendant’s failure to chal- lenge what the state perceives to be an “alternative holding” in the opinion of the Court of Appeals. But we do not read that opinion as announcing the “alternative holding” that the state identifies, and we reach the issue on which we allowed review. Cite as 369 Or 347 (2022) 355
We conclude that the legislature did not intend to require proof that a personality disorder played no role in bring- ing about the requisite lack of capacity, and, ultimately, we remand to the Court of Appeals for further consideration. A. Causation Analysis Under ORS 161.295 Because the elements of the GEI defense are estab- lished by statute, the question is what causal connection the legislature intended to require. See State v. Gaines, 346 Or 160, 171, 206 P3d 1042 (2009) (emphasizing that, in deter- mining the meaning of a statute, the court’s “paramount goal” is to discern the intent of the legislature). All require- ments for the GEI defense are contained in ORS 161.295, which, as applicable to defendant’s case, provided: “(1) A person is guilty except for insanity if, as a result of mental disease or defect at the time of engaging in crimi- nal conduct, the person lacks substantial capacity either to appreciate the criminality of the conduct or to conform the conduct to the requirements of law.
“(2) As used in chapter 743, Oregon Laws 1971,[6] the terms ‘mental disease or defect’ do not include an abnor- mality manifested only by repeated criminal or otherwise antisocial conduct, nor do they include any abnormality constituting solely a personality disorder.”
As with all questions of statutory construction, we turn to the analytical framework that we described in Gaines to determine whether the legislature intended to require proof that a defendant lacked capacity solely “as a result of mental disease or defect” and in no part as a result of a “personal- ity disorder.” See ORS 161.295. Under that well-established framework, we consider the text and context of the statute, and we consider legislative history “where that legislative history appears useful to the court’s analysis.” Gaines, 346 Or at 171-72. In this case, the legislative history is partic- ularly helpful to our understanding of what the legislature intended.
6 The reference in ORS 161.295(2) to “chapter 743, Oregon Laws 1971” is a reference to the comprehensive Oregon Criminal Code adopted in 1971, of which the GEI defense was a part. See Or Laws 1971, ch 743, § 36. 356 State v. Meiser
The text that governs defendant’s case is the prod- uct of two different legislative enactments. The relevant causation test—“as a result of mental disease or defect at the time of engaging in criminal conduct”—dates to when the statute was originally enacted as part of the comprehen- sive Oregon Criminal Code of 1971. Or Laws 1971, ch 743, § 36. As originally enacted, however, the statute specified just one exclusion from the terms “mental disease or defect,” for “an abnormality manifested only by repeated criminal or otherwise antisocial conduct.” Id. The exclusion of “any abnormality constituting solely a personality disorder” from what qualifies as “mental disease or defect” was added to ORS 161.295(2) in 1983, through the adoption of House Bill (HB) 2075. Or Laws 1983, ch 800, § 1. Thus, our inquiry into legislative intent takes into account both the 1971 and the 1983 legislatures. See State v. Swanson, 351 Or 286, 290, 266 P3d 45 (2011) (explaining that the proper inquiry for statutory construction focuses on “the intent of the leg- islature that enacted the statute,” although “we also con- sider any later amendments or statutory changes that were intended by the legislature to modify or otherwise alter the meaning of the original terms of the statute”). Both parties point us to legislative history indicat- ing that the 1983 Legislative Assembly enacted the person- ality disorder exclusion in ORS 161.295(2) to narrow the availability of the insanity defense. Significantly, however, the legislative history suggests that the legislature did not intend to narrow availability of the defense so thoroughly that a defendant’s proof would fail if a personality disor- der contributed in any part to the qualifying incapacity. This court has previously recited that legislative history in detail. Tharp v. PSRB, 338 Or 413, 426-30, 110 P3d 103 (2005) (quoting Beiswenger v. PSRB, 192 Or App 38, 48-51, 84 P3d 180, rev dismissed, 337 Or 669 (2004)).7 Here, we rely on that prior recitation where pertinent. 7 In Tharp, this court set out at length and relied upon a “detailed review of the legislative history leading to the legislature’s decision to exclude per- sonality disorders from the definition of mental disease or defect in ORS 161.295” from a recent Court of Appeals “opinion by [then-]Judge Landau.” 338 Or at 426 (discussing Beiswenger, 192 Or App at 48-51). We provide citations to the legislative history that is quoted in Tharp without further reference to Beiswenger. Cite as 369 Or 347 (2022) 357
As that recitation of the legislative history explains, the bill as originally introduced did not address “personal- ity disorders.” Tharp, 338 Or at 426. That changed after an early hearing, at which the Executive Director of the Psychiatric Security Review Board suggested that the leg- islature should explicitly addresse whether the definition of “mental disease or defect” included or excluded “personal- ity disorders” and the chair of the board testified that “the board supported the exclusion of ‘personality disorders’ from the definition of ‘mental disease or defect.’ ”8 Tharp, 338 Or at 426-27. At a subsequent hearing, Representative Peter Courtney asked for an amendment “that would accom- plish the exclusion of ‘personality disorders’ from the stat- utory definition of ‘mental disease or defect,’ ” and “Jeffrey Rogers, the chair of the legislative interim task force that had drafted the bill, * * * responded with the wording that is, in substance, the current law.” Tharp, 338 Or at 427-28. Specifically, Rogers proposed that the legislature add the phrase “nor does [the term ‘mental disease or defect’] include disorders characterized only as personality disorders.” Tape Recording, House Committee on Judiciary, HB 2075, May 13, 1983, Tape 324, Side A (statement of Jeffrey Rogers). He emphasized that the exclusion should include the word “only”—which became “solely” in the enacted provision—to indicate that a person who has “a personality disorder plus a psychosis * * * may still qualify.” Id. At the suggestion of legislative counsel, Rogers’s proposal to exclude “disorders characterized only as personality disorders,” see id., became an exclusion of “any abnormality constituting solely a per- sonality disorder,” Exhibit V, House Committee on Judiciary, May 31, 1983, HB 2075 (accompanying statement of Legal Counsel Linda Zuckerman). But legislative counsel told the committee that the change was not substantive—that the 8 The scope of “mental disease or defect” also is at issue in cases in which a petitioner who has proven a GEI defense later seeks discharge from commitment or from the Psychiatric Security Review Board’s jurisdiction on the ground that the person is “ ‘no longer affected by mental disease or defect.’ ” See, e.g., Tharp, 338 Or at 416-18, 416 n 1 (discussing the versions of ORS 161.341(4) and ORS 161.351 then in effect and explaining that the petitioner challenged the board’s conclusion that he was not entitled to discharge because, on account of his sub- stance dependency, he continued to be affected by a “mental disease or defect”). 358 State v. Meiser
exclusion was still “to the effect that the mental disease or defect also does not include disorders characterized only as personality disorders.” Tape Recording, House Committee on Judiciary, May 31, 1983, HB 2075, Tape 386, Side A (statement of Legal Counsel Linda Zuckerman). Subsequently, “[t]he bill moved to the floor of the House, where the floor manager, Representative Courtney, explained that it contained a ‘personality exclusion’ that accomplished a narrowing of the definition of ‘mental dis- ease or defect.’ ” Tharp, 338 Or at 428. To further explain the exclusion, Representative Courtney quoted from a let- ter that the board’s executive director had submitted to the House Judiciary Committee: “ ‘Right now if a person has what is considered a personality disorder, * * * they’re able to claim that they have a mental disease or defect. We now no longer, with this piece of legis- lation, will allow an individual to say that I have a mental disease or defect because I have a personality disorder.’ ” Id. (quoting Audio Recording, House Floor Debate, HB 2075, June 16, 1983, Reel 19, Track I (statement of Rep Peter Courtney)). The bill passed the House. Id. at 429. When the bill moved to the Senate, Representative Courtney introduced it to the Senate Judiciary Committee by “explain[ing] that it ‘would remove personality disorders as a category that could be relied on for use of the insan- ity plea.’ ” Id. (quoting Tape Recording, Senate Committee on Judiciary, HB 2075, June 29, 1983, Tape 234, Side A (statement of Rep Peter Courtney)). Ultimately, both houses passed the bill, and it was signed into law. Id. The text of the 1983 amendment captures the leg- islative intent to narrow the definition of a “mental disease or defect” to exclude personality disorders—as the chair of the Psychiatric Security Review Board requested, and as legislators reiterated as the bill moved through the legisla- ture. By specifying in ORS 161.295(2) that “the terms ‘men- tal disease or defect’ do not include * * * any abnormality constituting solely a personality disorder,” the legislature expressed its intention to remove the category of “disorders characterized only as personality disorders” from the larger Cite as 369 Or 347 (2022) 359
group of “mental disease or defect” that can “be relied on for use of the insanity plea” under ORS 161.295(1).9 See Tape Recording, House Committee on Judiciary, HB 2075, May 13, 1983, Tape 324, Side A (statement of Jeffrey Rogers) (proposing wording); Tape Recording, Senate Committee on Judiciary, HB 2075, June 29, 1983, Tape 234, Side A (state- ment of Rep Peter Courtney) (explaining effect of the bill); see also Webster’s Third New Int’l Dictionary 1143 (unabridged ed 2002) (defining “include” to mean “to place, list, or rate as a part or component of a whole or of a larger group, class, or aggregate”). Accordingly, the effect of the 1983 amendment addressing personality disorders is to place a limitation on the “mental disease or defect” element of the defense set out in ORS 161.295(1). Significantly, however, the 1983 text did not add a similar limitation to the causation element set out in ORS 161.295(1). That is to say, it did not affirmatively require defendants with a personality disorder and a co-occurring condition that is a qualifying “mental disease or defect” to prove that their incapacity existed solely “as a result of men- tal disease or defect” and in no part as a result of a personal- ity disorder. And reading in that more extensive limitation would be in tension with the 1983 legislature’s intent that a person who has “a personality disorder plus a psychosis * * * may still qualify” for the defense. See Tape Recording, House Committee on Judiciary, HB 2075, May 13, 1983, Tape 324, Side A (statement of Jeffrey Rogers). By addressing personality disorders only through an exclusion in ORS 161.295(2), the legislature left unchanged the meaning of “as a result of mental disease or defect” in the affirmative defense set out in 1971. And nothing about the text or legislative history of that 1971 enactment per- suades us that the legislature intended “as a result of men- tal disease or defect” to mean solely “as result of mental dis- ease or defect.” In ordinary usage, the term “result” is not
9 Given the text and legislative history, we reject an argument advanced by amicus Disability Rights Oregon that “abnormality” refers to a defendant’s men- tal state as a whole—meaning that personality disorders are included within the broad category “mental disease or defect,” for purposes of proving the GEI defense, as long as the defendant has some other mental disorder or condition. We reject that interpretation as contrary to what the legislature intended. 360 State v. Meiser
limited to the concept of sole causation. See Webster’s at 1937 (defining noun “result,” most pertinently, as “something that results as a consequence, effect, issue, or conclusion”). The legislative history of ORS 161.295 also suggests that the 1971 legislature did not intend the “as a result of” standard to be limited to a solely “as a result of” standard. Like those who drafted and adopted the 1983 amendment, those who drafted and adopted the 1971 statute were con- cerned that the defense might be used by a category of offend- ers whom the drafters did not view as possessing “a men- tal disease or defect.” In 1971, the category of concern was “psychopaths” (or “sociopaths”), and the statute addressed that concern by specifying that “the terms ‘mental disease or defect’ do not include an abnormality manifested only by repeated criminal or otherwise antisocial conduct.” Or Laws 1971, ch 734, § 36 (emphasis added); see Commentary to Criminal Law Revision Commission Proposed Oregon Criminal Code, Final Draft and Report § 36, 35 (July 1970) (discussing concerns regarding “psychopaths”). The drafters of the provision told the 1971 legislature that the purpose of the exclusion was to prevent “recidivists” from “qualify- [ing] for the defense merely by being labeled psychopaths.” Commentary § 36 at 35. By structuring the statute to exclude those who were “merely” labeled as “psychopaths,” see id. (or those demonstrating “an abnormality manifested only by repeated criminal or otherwise antisocial conduct,” see Or Laws 1971, ch 734, § 36(2) (emphasis added)), the leg- islature left open the possibility that the defense could be available to offenders who suffered from a “mental disease or defect” in addition to whatever label attached to their repeated criminal or antisocial conduct. And we understand the legislature to have intentionally struck that balance. We understand the 1983 legislature to have intended to retain that balanced approach when it amended subsec- tion (2) to also exclude “personality disorders” from the defi- nition of “mental disease or defect.” That exclusion—like the original exclusion—specifies certain mental conditions that are not included within the broader terms “mental disease or defect,” and in doing so, narrows access to the defense set out in subsection (1). But it does not make the defense so narrow as to require that a person who can demonstrate the Cite as 369 Or 347 (2022) 361
requisite lack of substantial capacity “as a result of mental disease or defect” also prove that a co-occurring personal- ity disorder in no part contributed to the incapacity. Thus, we agree with defendant that the Court of Appeals erred in concluding that defendant could prevail on his GEI defense only if he proved that his co-occurring personality disorder played no part in causing the requisite lack of substantial capacity. B. Proper Disposition That conclusion answers the question that this court allowed review to address, but it does not fully resolve whether defendant was entitled to prevail on his GEI defense. As explained above, because the Court of Appeals concluded that defendant was not entitled to prevail on the causation element of the defense, it did not resolve whether the evidence compelled a finding in defendant’s favor on the third element of the defense: whether, under ORS 161.295(1), he lacked “substantial capacity either to appreciate the criminality of the conduct or to conform the conduct to the requirements of law.” Meiser, 308 Or App at 588. In addition, the Court of Appeals did not consider—except under the “sole cause” test that we have rejected—whether the evidence compelled a finding that defendant proved that he had experienced any qualifying incapacity “as a result of mental disease or defect.” As the state emphasizes, any answer to the latter question may turn on whether the phrase “as a result of” in ORS 161.295(1) means that the qualifying “mental disease or defect” must be sufficient, on its own, to bring about the requisite incapacity, or whether the legislature intended to require some lesser degree of causal contribution from the qualifying “mental disease or defect.”10 As a matter of judicial efficiency, this court some- times resolves issues beyond those as to which we allowed review, rather than remanding to the Court of Appeals to resolve remaining issues, but we decline to do so in this case.
10 In its amicus curiae brief, Disability Rights Oregon argues that the statute requires but-for causation: But for the “mental disease or defect,” the incapacity would not have occurred. See W. Page Keeton, Prosser and Keeton on the Law of Torts § 41, 266 (5th ed 1984) (defining the but-for rule of causation in the tort context). Defendant expresses no opinion on that argument. 362 State v. Meiser
Both the remaining evidentiary issues and the remaining statutory construction issue would benefit from consider- ation in the first instance by the Court of Appeals. The decision of the Court of Appeals is reversed in part, and the case is remanded to the Court of Appeals for further proceedings.
