1 1 This case comes before us on a writ of certiorari. The State of Utah challenges the decision of the court of appeals to reverse the conviction of Billy Frank Spillers (Defendant) for first degree murder and to remand the case for a new trial. We affirm the court of appeals' holding that Defendant was entitled to jury instructions on both extreme emotional distress manslaughter and imperfect legal justification manslaughter.
BACKGROUND
12 During the afternoon of October 25, 1999, Defendant and James Jackson were at Defendant's home. Witnesses testified that an argument broke out between the two men, although Defendant testified that the argument was actually between Jackson and another man. Witnesses testified that, as the argument escalated, Defendant brandished a gun and ordered everyone to leave. Defendant admitted at trial that he told everyone to leave, but he denied threatening anyone with a firearm.
{3 Shortly thereafter, Defendant and Jackson left Defendant's home. Defendant followed Jackson to Jackson's home, where they began arguing. The argument escalated, and Jackson accused Defendant of snitching on him to drug enforcement agents regarding a drug deal in Kansas City. Defendant testified that Jackson retrieved a gun from the living room couch, returned to the kitchen, and began threatening him, making Defendant feel nervous. Defendant then turned away from Jackson, at which point Jackson struck Defendant with the gun on the back of the head. Defendant testified that the blow left him feeling cloudy, dazed, uncomfortable, and scared. Defendant stated that, after being struck, he turned to face Jackson, pushed him backwards, and told him to back away. Then, according to Defendant, Jackson approached him with his arm cocked to strike again. At that point, Defendant pulled a gun from his waistband and shot Jackson in the chest. At trial, Defendant stated that he recalled shooting Jackson only once, although evidence revealed that Jackson was shot three times.
11 4 Two witnesses present in the house at the time of the shooting testified that they heard Defendant and Jackson arguing, followed by a series of gunshots. The witnesses differed about the timing of the three shots.
5 Defendant testified that after shooting Jackson, he took Jackson's gun, as well as his own, and ran out of the house, breaking his ankle during his flight and dropping both guns in the yard. He retrieved Jackson's gun and fled the scene. Defendant was apprehended later that evening. He was booked into the Salt Lake County jail and charged with first degree murder.
T6 After his arrest, a forensic nurse examined Defendant and found a two-inch hemato-ma on the back of his head, consistent with Defendant's having received a wound the pri- or day. Additionally, she observed that Defendant's pupils appeаred sluggish, which could have been the result of the blow to the head.
T7 The medical examiner testified that Jackson was shot three times-once in the chest, onee in the thigh, and onee through the penis. The first shot was fatal and severed Jackson's spine, causing him to collapse immediately, while the second and third shots were fired as he lay on thе floor. The
11 8 Several witnesses testified that Jackson had a reputation for violence, aggressive behavior, and an explosive temper.
T9 The district court concluded that the evidence presented at trial did not warrant a jury instruction for either extreme emotional distress manslaughter or imperfect legal justification manslaughter, and Defendant was convicted of first degree murder pursuant to Utah Code section 76-5-208 (1999). Defendant appealed his conviction, and the court of appeals reversed, holding that Defendant was entitled to jury instructions for both extreme emotional distress manslaughter and imperfect legal justification manslaughter. We granted certiorari to determine (1) whether Defendant was entitled to a manslaughter jury instruction based on extreme emotionаl distress, and (2) whether Defendant was entitled to a manslaughter jury instruction based on imperfect legal justification. Jurisdiction is appropriate pursuant to Utah Code section 78-2-2(5) (2002).
STANDARD OF REVIEW
110 "On certiorari, we review the court of appeals' decision for correctness, giving its conclusions of law no deference." State v. Casey,
ANALYSIS
111 The State argues that the court of appeals erred in reversing the trial court's decision not to instruct the jury on extreme emotional distress and imperfect legal justification manslaughter. The State argues that under no rational view of the evidence could a jury have both acquitted Defendant of murder and convicted him of manslaughter and that even if an instruction on lesser included offenses was warranted, that error was harmless. We disagree.
112 In State v. Baker,
113 Murder may be reduced to manslaughtеr where a defendant caused a person's death "under the influence of extreme emotional distress for which there is a reasonable explanation or excuse." Utah Code Ann. § (8)(d) (1999). "[The reasonableness of an explanation or exeuse ... shall be determined from the viewpoint of a reasonable person under the then еxisting cireumstances." Id. § 76-5-208(8)(c).
114 A person suffers extreme emotional distress when exposed to " 'extremely unusual and overwhelming stress' such that the average reasonable person" would react by experiencing a loss of self-control. State v. Shumway,
1 15 In Shumway, this court held that the defendant, a minor, was entitled to an extreme emotional distress manslaughter instruction when he stabbed his friend during a sleepover. Id. ¶¶ 2, 10-11, 13. The victim, upset with the defendant for beating him at video games, retrieved a knife and began lunging at the defendant. Id. ¶ 10. The defendant gained control ovеr the knife and repeatedly stabbed the victim. Id. At trial, witnesses testified that the victim had a tendency towards aggression. Id. This evidence, when viewed in the light most favorable to the defense, offered a sufficient rational basis for a jury to conclude that the defendant was experiencing extreme emotional distress and to convict on the lesser included offense. Id. ¶ 13.
1 16 Like Shumway, evidence in this case could be interpreted to support Defendant's contention that he experienced extreme emotional distress and was therefore entitled to a manslaughter instruction. Defendant testified that he and Jackson were arguing prior to the altercation and that Jackson was uрset with him, accusing him of snitching to drug enforcement officers. The tone of the conversation made Defendant nervous. Defendant stated that Jackson retrieved a firearm and struck Defendant on the back of the head. Defendant testified that the blow left him cloudy, dazed, uncomfortable, and scared. According to the nurse's testimony, the blow may have resulted in a two-inch hematoma that was present on Defendant's head the day after the shooting. Defendant testified that after being struck, he turned to face Jackson, who was cocking his arm back to strike Defendant again. At that point, Defendant shot Jackson three times, although at trial he testified that he remembered firing only a single shоt. Further, witnesses testified that Jackson had a reputation for violence. Thus, a rational jury could, adopting Defendant's version of events, find that he was experiencing extreme emotional distress for which there was a reasonable explanation or excuse when he shot Jackson.
I 17 The State contends that unlike Shum-way, in this case therе was no rational basis in the evidence presented at trial to warrant the extreme emotional distress manslaughter instruction. Rather, the State maintains that a rational jury could not conclude that Defendant was overwhelmed such that a reasonable person would experience a loss of self-control. The substance of the State's argument is twofold.
18 First, the State's assertion rests on its own conclusion that Defendant acted "rationally" throughout the encounter; however, the question of whether Defendant acted "rationally" is a question of fact properly belonging to the jury. While a jury could adopt the State's version of events and convict Defendant of murder, а jury could also believe Defendant's interpretation of the evidence and conclude that he was not acting rationally, but rather was under extreme emotional distress as a result of Jackson's attack and convict on the lesser offense of manslaughter.
119 Second, the State contends that Defendant did not present evidence that he was in fact experiencing "extreme emotional distress." Rather, the State maintains that Defendant merely testified that he felt
a reasonable doubt as to any element of the crime." Torres,
T20 Reviewing the evidence presented at trial in the light most favorable to the defense, we hold that there was evidence from which a jury reasonably could conclude that Defendant was under the influence of extreme emotional distress at the time of the shooting. A jury could infer Defendant's mental state from the testimony of Defendant and others that supported his theory of the case. This evidence includes Defendant's testimony that he felt nervous and that the blow to his head left him feeling cloudy, dazed, uncomfortable, and scared. It also includes Defendant's rendition of the events that tоok place the night of the shooting, the testimony of the nurse regarding Defendant's wound, the medical examiner's testimony of the positioning of Jackson's body, the evidence of Jackson's reputation for violence, and any other evidence that substantiated Defendant's theory of the case. Based on the entirety of the evidencе at trial, a jury could choose to believe Defendant's version of events and conclude that Defendant was experiencing extreme emotional distress at the time of the shooting for which there was a reasonable explanation or excuse.
II. DEFENDANT WAS ENTITLED TO A JURY INSTRUCTION FOR IMPERFECT LEGAL JUSTIFICATION MANSLAUGHTER
121 The court of appeals found that the same evidence that supported Defendant's theory of extreme emotional distress manslaughter also supported his theory of imperfect legal justification manslaughter. State v. Spillers,
122 Under Utah Code section 76-5-208, murder may be reduced to manslaughter when the defendant caused another's death "under a reasonable belief that the cireum-stances provided а legal justification or excuse for his conduct although the conduct was not legally justifiable or excusable under the existing circumstances." Utah Code Ann. § 76-5-208(B)(a)(ii), (@)(d) (1999). "[The reasonableness of an explanation or exeuse ... shall be determined from the viewpoint of a reasonable person under the then existing cireumstances." Id. § 76-5-208(8)(c).
123 At trial, the сourt found the evidence sufficient to instruct the jury on perfect self-defense but not on imperfect legal justification manslaughter.
2
This was error. In State v. Howell, this court stated that for both perfect and imperfect self-defense, "the
III. FAILING TO INSTRUCT THE JURY ON THE LESSER INCLUDED OFFENSES WAS NOT HARMLESS ERROR
$24 Finally, the State argues that any error in the jury instructions was harmless. "[Hlarmless error is an error that is sufficiently inconsequential that there is no reasonable likelihood that it affected the outcome of the proceedings." State v. Evans,
CONCLUSION
125 We agree with the court of appeals that there was a sufficient rational basis in the evidence for the jury to acquit Defendant of murder and convict him of manslaughter. Accordingly, Defendant was entitled to jury instructions for both extreme emotional distress and imperfect legal justification manslaughter. We affirm the court of apрeals and remand the case to the district court for a new trial.
Notes
. The State argues that the Baker standard is inapplicable and that this court should consider Defendant's request for jury instructions under the test for affirmative defenses. However, the standards apрlied when a defendant is entitled to have the jury instructed on an affirmative defense or on a lesser included offense are indistinguishable. In either case, a defendant is entitled to an instruction ""if there is any reasonable basis in the evidence." State v. Torres,
. At oral argument, the State conceded that Defendant was entitled to a perfect self-defense claim.
