JUAN JAVIER OQUENDO, Petitioner,
vs.
STATE OF FLORIDA, Respondent.
October 9, 2025
FRANCIS, J.
This case concerns Florida’s self-defense standard and
whether evidence of a defendant’s post-traumatic stress disorder
(PTSD) is relevant to his claim of self-defense. The Second District
Court of Appeal certified conflict between its decision in Oquendo v.
State, 357 So. 3d 214 (Fla. 2d DCA 2023), and the First District
Court of Appeal’s decision in State v. Mizell, 773 So. 2d 618 (Fla. 1st
DCA 2000), on the question of whether expert testimony about a
defendant’s PTSD is ever legally relevant to a self-defense theory.
The Second District held that evidence of PTSD is categorically irrelevant given that self-defense turns on a reasonably prudent
person standard, i.e., what a reasonably prudent person would do
under the circumstances. Oquendo, 357 So. 3d at 221. The First
District, on the other hand, approved the admission of expert PTSD
testimony in support of a self-defense theory where the trial court
placed strict limitations on the use of such evidence, similar to
those imposed upon the use of expert testimony concerning
battered spouse syndrome. Mizell, 773 So. 2d at 620 (citing State v.
Hickson, 630 So. 2d 172, 173 (Fla. 1993)). The First District based
its decision on the language in the standard jury instruction on
self-defense requiring the jury to find that the defendant “actually
believed that the danger was real.” Id. at 621 (citing Fla. Std. Jury
Instr. (Crim.) 3.04(d)). 1
We have jurisdiction to resolve this conflict. See art. V,
§ 3(b)(4), Fla. Const. 2 In doing so, we recognize that a showing of
1. Between the time Mizell was decided in 2000 and Oquendo was decided in 2023, the standard criminal jury instruction on self- defense was renumbered from 3.04(d) to 3.6(f). See Fla. Std. Jury Instr. (Crim.) 3.6(f).
2. Though we may reach extra issues when appropriate, see Fla. R. App. P. 9.120(f); State v. Ivey, 285 So. 3d 281, 284 (Fla. 2019), we decline to reach the second issue raised by Oquendo
-2- self-defense legally involves both an objective component, to which
the reasonable person standard applies, and a subjective
component, which leaves room for the admission of other relevant
evidence establishing the overall circumstances. As to the objective
component, we agree with the Second District that evidence of
PTSD is categorically irrelevant. But to the extent PTSD evidence
may be relevant to the subjective component of a defendant’s self-
defense theory, we disapprove the Second District’s decision in
Oquendo and approve the First District’s decision in Mizell.
However, because we find no reversible error in the outcome of this
case, we ultimately approve the result in Oquendo and uphold
Oquendo’s conviction and sentence.
I. Background
Juan Javier Oquendo was charged with first-degree murder for
the fatal shooting of James Cason in 2015 outside a bar in Pinellas
regarding jury instructions because it is outside the scope of the conflict issue and was not expressly addressed by the Second District’s decision, see Agatheas v. State, 77 So. 3d 1232, 1236 n.1 (Fla. 2011) (“Because the Fourth District did not specifically address this claim, and it is outside the scope of the conflict issue, we decline to address it.”).
-3- County where Oquendo’s sister worked. Oquendo, a regular at the
bar, was playing pool and talking to his sister on the night of the
shooting. After he went into a restricted area of the bar, he was told
to leave. He left and did not seem upset as he did so.
The victim, Cason, had also been drinking at the bar that
night and was intoxicated. 3 Cason left a few minutes before
Oquendo came out, according to a former security guard outside
the club who described himself as an “associate[]” of Cason’s. That
security guard testified that when Oquendo exited the bar, Oquendo
grabbed him from behind in a bear hug and said, “You lucky I like
you.” After that, the security guard saw Oquendo pacing back and
forth at the side of the building and said he seemed agitated.
The security guard testified that a short time after his
encounter with Oquendo, Cason’s car pulled up, and Cason blew
his horn to signal to Oquendo to get out of the way. Oquendo went
to the driver’s side of Cason’s car and grabbed the door handle.
Cason let down the window and said, “What are you doing? This is
my car[.]” Oquendo said, “Oh, my bad. I thought this was my
3. The medical examiner testified that Cason’s blood alcohol level was .118, above the legal limit of .08.
-4- friend[’s] car because he has a car like this.” The two exchanged
words. Oquendo then took a pool stick he had out of its case and
jabbed it into Cason’s window. Cason said, “Don’t worry about it. I
got something for you. I’ll be right back.”
The testimony of the trial witnesses differed as to what
happened next, which the Second District summarized as follows:
Oquendo testified that he saw the victim reach over and produce a gun. He tried to knock the gun from the victim’s hand with his pool stick. Oquendo grabbed the victim’s arm. He took the gun from the victim, then the gun went off inside the vehicle once or twice. He did not know that the victim had been shot; the victim’s vehicle began moving forward, and Oquendo thought that he was going to be shot or run over. So, Oquendo said that he fired the weapon several times toward the vehicle. Other witnesses recounted the events differently. One witness who claimed to be nearby heard someone say, “I got mine.” Another heard the victim say: “Don’t worry about it. I got something for you. I’ll be right back.” One witness testified that he saw Oquendo punch into the car and hit the driver. Then Oquendo pulled out a gun and started shooting. Another witness testified that he saw Oquendo poke his pool stick into the vehicle; no gun was in his hand when that occurred. However, the witness said that he was sure that Oquendo did not pull a gun from the victim’s hand and that there was no struggle over a gun at any point; the gun came from Oquendo’s person. The witness saw Oquendo pull the trigger and fire a shot at the victim. Another witness testified that after the first shot was fired, the victim’s vehicle moved forward and hit a parked car.
Oquendo, 357 So. 3d at 216.
-5- According to the Second District, the physical evidence showed
the gun was fired from a short distance and there were multiple
bullet holes in Cason’s vehicle:
The medical examiner testified that the victim died after sustaining a single gunshot wound to the head, above his left ear. The gun was fired from one and a half to two feet away from the victim. Crime scene technicians located multiple bullet holes in the victim’s vehicle as well as twelve shell casings.
Id. Additionally, according to the testimony of Horace Lee, Oquendo
admitted that he also had a gun:
After the shooting, Oquendo fled. He went to the home of Horace Lee, who dated Oquendo’s mother when Oquendo was young. Lee testified that Oquendo told him “[t]hat he shot someone.” Oquendo also told Lee, “His gun didn’t go off, mine did.”
Id. (alteration in original).
Though Oquendo maintained that the gun accidentally went
off during the struggle with Cason, the jury was instructed on self-
defense. Ultimately, the jury acquitted Oquendo of first-degree
murder and convicted him of the lesser included offense of
manslaughter. The jury also found that Oquendo carried, used, or
displayed a firearm during commission of the offense. The Second
District affirmed Oquendo’s manslaughter conviction on appeal.
-6- A. Unadmitted Expert Testimony on PTSD
One of the major issues raised by Oquendo on appeal was
whether the trial court properly denied his request to present expert
testimony from clinical and forensic psychologist Dr. Jethro
Toomer, who would have opined that Oquendo suffered from PTSD.
During a pretrial proffer, Dr. Toomer testified that he reached this
conclusion after interviewing Oquendo and evaluating him using a
number of tests, in addition to observing Oquendo’s behavior and
examining his personal history, which included familial
abandonment in childhood, having witnessed three people he knew
being killed, having been kidnapped, and having been mugged at
least twice. Dr. Toomer opined that Oquendo had suffered from
PTSD “for some time,” including the night of the shooting.
Dr. Toomer also explained that PTSD results when an
individual is exposed to stressors, situations, or an environment
“that is threatening and that may, at times, create[] risk and the
threat of harm and loss of life.” PTSD causes an individual’s overall
functioning to be impaired “cognitively, behaviorally, [and]
emotionally,” so these individuals “don’t weigh alternatives,”
“project consequences,” “manage conflicted data,” or “learn from
-7- past experiences.” This means that behaviorally, these individuals
are “impulsive” and “unable to . . . assess situations appropriately
and come to rational conclusions,” and their “instinct for survival
remains elevated and is easily triggered.” Dr. Toomer explained
that, under substantial stress, an individual suffering from PTSD is
more likely to perceive a situation as threatening and to act on
impulse and without thinking.
Dr. Toomer agreed that Oquendo had only reported his version
of events: that Cason produced a gun, that Oquendo gained control
of the gun, and that the car started moving. Also, Oquendo did not
admit to Dr. Toomer that he intentionally pulled the trigger and
shot Cason.
The trial court denied Oquendo’s request to admit Dr.
Toomer’s testimony. In so doing, the court rejected Oquendo’s
argument that a defendant’s perceptions are relevant to the issue of
self-defense under the First District’s holding in Mizell, and found
that Dr. Toomer actually gave no opinion on the issue of self-
defense. The trial court found that Oquendo offered Dr. Toomer’s
testimony only to show that Oquendo had PTSD and that this
would carry a risk of confusing the jury about the significance of
-8- diminished capacity. 4 The trial court also noted that the language
of the self-defense instruction in Florida Standard Criminal Jury
Instruction 3.6(f) refers to what a defendant “reasonably believed”
and what “the reasonabl[y] cautious and prudent person” would
have done. Finally, the court noted that Oquendo never admitted to
intentionally shooting Cason, which is generally required to claim
self-defense. Thus, the court refused to admit Dr. Toomer’s opinion
about Oquendo’s PTSD, reasoning that the testimony would not
assist the jury in making its decision.
B. The Conflict Opinions
Oquendo challenged the trial court’s ruling on the
admissibility of Dr. Toomer’s testimony on appeal. The Second
District found no error in the exclusion of Oquendo’s proffered
expert testimony on PTSD because it determined that such evidence
4. The trial judge cited to State v. Storer, 920 So. 2d 754 (Fla. 2d DCA 2006), as the basis for this conclusion. The court appears to have focused on Storer’s description of Mizell as the First District “declin[ing] to quash the [pretrial] order [admitting PTSD evidence under specific conditions] despite the risk that the evidence might confuse the jury about the significance of diminished capacity.” Id. at 759 (emphasis added).
-9- is not relevant to the reasonable person standard required by
Florida’s jury instruction on self-defense:
Use of evidence of a disorder affecting a defendant’s perceptions would necessarily be—as it was here—in support of a theory that the defendant’s belief was more reasonable to him than it might have been to one not suffering from such a disorder. Such use, premised as it is on the defendant’s subjective comprehension of the situation, is incompatible with the objective standard of reasonableness required to support the justification of self[-]defense.
Oquendo, 357 So. 3d at 217.5 In doing so, the Second District
certified conflict with the First District’s decision in Mizell and
thoroughly examined that case. Thus, we find it helpful to first
thoroughly discuss Mizell to clarify Oquendo’s disagreement with it.
5. The Second District also noted that “[a] theory of defense that the firearm discharged accidentally is not necessarily inconsistent with a theory of self[-]defense (and therefore does not categorically preclude a self[-]defense instruction).” Oquendo, 357 So. 3d at 217 (citing Williams v. State, 588 So. 2d 44, 45 (Fla. 1st DCA 1991)); see also Williams, 588 So. 2d at 45 (“[W]here there is evidence indicating that the accidental infliction of an injury and the defense of self[-]defense or defense of another are so intertwined that the jury could reasonably find that the accident resulted from the justifiable use of force, an instruction on self[-]defense or defense of another is not logically precluded.”).
- 10 - 1. Mizell
In Mizell, the First District denied the State’s petition for writ
of certiorari seeking review of a pretrial order allowing Mizell, a
Vietnam veteran, to present evidence of PTSD “under certain limited
conditions” in his trial for attempted second-degree murder, in
which he was claiming self-defense. 773 So. 2d at 619.6 Mizell
quarreled with the victim, Benny Hayes, at the nearby home of a
mutual friend, and Hayes made threats and derogatory comments
to Mizell. Id. Mizell attempted to avoid Hayes and left several times
when Hayes reappeared at the home. Id. Eventually, Mizell, who
had been drinking, fell asleep on the couch near the home’s open
front door; he “awoke to find Hayes standing over the couch saying,
‘You son-of-a-bitch, I’m going to cut your throat.’ ” Id. At that
point,
Hayes then placed a hand into his pocket. Seeing this, Mizell picked up a stick and hit Hayes. Mizell claims he then went blank, and the next thing he remembers is seeing Hayes very bloody. The arrest report indicates that Mizell hit Hayes several times. Hayes was rendered unconscious by the attack, and he also lost several teeth.
6. Mizell “experienc[ed] several disturbing incidents” while in Vietnam, which led to a diagnosis and treatment for PTSD. Id.
- 11 - Id. at 619-20.
Mizell intended to offer expert testimony from Dr. Harry Krop,
a clinical psychologist, to explain (a) that Mizell has PTSD, (b) what
PTSD is, and (c) how it affects a person’s perceptions. Id. at 620.
The State filed a motion in limine to prevent the introduction of this
expert testimony. Id. The trial court denied the motion but
provided five specific conditions that must be met in order for Mizell
to offer the testimony:
1. [Mizell] must lay a predicate by testifying[.] 2. Thereafter, Dr. Krop may testify as to the Post[-] Traumatic Stress Disorder. 3. Dr. Krop may reveal [Mizell’s] alleged background but may not vouch for it. 4. Dr. Krop may not refer to the Battered Wife’s Syndrome. 5. Dr. Krop may not offer an opinion as to the validity of self-defense in this case.
Id.
On certiorari review, the State argued, first, that Mizell sought
to introduce the testimony as diminished capacity evidence to
negate the requisite criminal intent, and, second, that even if it was
not diminished capacity evidence, it was inadmissible because it
was irrelevant to the question of self-defense. Id. The First District
rejected the first argument, finding that the PTSD evidence was
- 12 - being offered by Mizell as “state-of-mind evidence, quite analogous
to battered spouse syndrome (BSS) testimony that has in fact been
approved many times.” Id. (citing Hickson, 630 So. 2d at 173). The
First District also rejected the State’s second argument, holding
instead that “PTSD evidence is relevant on the question of self-
defense.” Id. at 621. As the First District explained,
The standard jury instruction for self-defense, which the trial judge quoted during the hearing, indicates that a defendant’s perceptions are relevant when assessing applicability of self-defense. See Fla. Std. Jury Instr. (Crim.) [3.04(d)] (“Based upon appearances, the defendant must have actually believed that the danger was real.”). The cases that admit evidence of BSS do so to help the jury understand why the victim would subjectively fear increased aggression against her. See Hawthorne v. State, 408 So. 2d 801, 806-07 (Fla. 1st DCA 1982) (“The expert testimony would have been in order to aid the jury in interpreting the surrounding circumstances as they affected the reasonableness of her belief . . . that because she suffered from the syndrome, it was reasonable for her to have remained in the home and at the pertinent time, to have believed that her life and the lives of her children were in imminent danger.”).
The First District also noted that the trial court’s five
conditions would avoid any danger of the psychologist’s testimony
presenting Mizell’s testimony “by the backdoor” to avoid cross-
- 13 - examination by the State. Id. The conditions also prohibited using
the psychologist’s testimony to improperly bolster Mizell’s version of
events. Id.
2. Oquendo
In Oquendo, the Second District took issue with the First
District’s conclusion in Mizell that the self-defense standard in
Florida includes a subjective component, explaining that
[t]he First District’s conclusion does not follow from its premise, in part because its rationale was based on an incomplete analysis of the self-defense jury instruction. See id. (relying on the jury instruction’s admonition that “[b]ased upon appearances, (defendant) must have actually believed that the danger was real.” (quoting Fla. Std. Jury Instr. (Crim.) [3.04(d)]). Of course, it is true that a defendant’s perceptions are relevant—what he ascertained with his senses constitutes the circumstances under which he was required to assess whether the threat justified the use of force he exerted. However, that does not make the self-defense test a subjective one, and it does not follow that a defendant’s misperceptions—his misunderstanding of reality as altered by a disorder such as PTSD—are relevant. The self-defense jury instruction not only requires that the defendant have “actually believed that the danger was real” but also that his belief was objectively reasonable: “The danger need not have been actual; however, . . . the appearance of danger must have been so real that a reasonably cautious and prudent person under the same circumstances would have believed that the danger could be avoided only through the use of that [force] [or] [threat of force].” Fla. Std. Jury Instr. (Crim.) 3.6(f) (brackets in original) (emphasis added). Evidence that a defendant’s
- 14 - perceptions might have been altered by a condition such as PTSD—or that his tendency to perceive danger was uniquely heightened compared to others who do not suffer from such a condition—is not probative of what a reasonably cautious and prudent person under the same circumstances would have believed to be the extent of the danger or lack thereof. Cf. § 90.401, Fla. Stat. (2015) (“Relevant evidence is evidence tending to prove or disprove a material fact.” (emphasis added)). Evidence of Oquendo’s PTSD would only go to show that his reaction was objectively unreasonable by virtue of a potential misperception of the dangerousness of the situation—i.e., that something others would not deem to be dangerous appeared to him to be so. Cf. § 776.012(2) (providing a justification for a defendant’s use of force “if he or she reasonably believes” his or her use of force was necessary (emphasis added)).
357 So. 3d at 218.
The Second District also held that Oquendo’s proffered PTSD
evidence was properly excluded as inadmissible diminished
capacity evidence, since “[a]llowing admission of evidence of the
defendant’s unique mental state when it is not relevant to a
permissible defense or justification could invite confusion and
potentially mislead the jury to excuse acts for which a defendant is
culpable under the law.” Id. at 219.
Finally, the Second District rejected the reasoning in Mizell
that the admissibility of battered spouse syndrome evidence
supports finding that PTSD evidence is relevant to self-defense. Id.
- 15 - The Second District reasoned that the admissibility of battered
spouse syndrome to support a theory of self-defense is “not for the
purpose of justifying a defendant’s misperception of reality or to
explain why an unreasonable belief was nonetheless justifiable due
to her condition,” but rather
to show why the defendant’s actions were reasonable—to show that in spite of a reasonable perception of danger from the battering spouse, the battered defendant would remain in the home with her batterer where she may resort to the exertion of force against him to prevent imminent death or great bodily harm. Thus, unlike PTSD evidence, battered-spouse syndrome evidence does not tend to show that a sufferer’s perceptions were impaired or altered by the condition; rather, it goes to show that while a defendant’s perception of the danger was reasonable, her choice to remain in the dangerous situation—despite the risk she would have to exert force to protect herself—was also reasonable.
Id. at 219-20 (citations omitted).
Thus, the Second District in Oquendo certified conflict with the
First District’s decision in Mizell.
II. Analysis
Whether Florida’s self-defense standard is solely governed by
the objective reasonable person standard or also encompasses a
subjective component that may allow evidence of PTSD is a pure
- 16 - question of law that we review de novo. Cf. State v. Floyd, 186 So.
3d 1013, 1019 (Fla. 2016) (noting that whether a standard criminal
jury instruction on self-defense is misleading with respect to the
duty to retreat is a pure question of law subject to de novo review).
To the extent we consider the correctness of the trial court’s ruling
that Oquendo’s expert testimony on PTSD was inadmissible, we
review for an abuse of discretion. See Twilegar v. State, 42 So. 3d
177, 194 (Fla. 2010) (“As a general rule, a trial court’s ruling
concerning the admissibility of evidence will be sustained on review
absent an abuse of discretion.”).
In resolving the interdistrict conflict, we first examine the
statutory definition of self-defense in section 776.012(2), Florida
Statutes (2015). We then examine the text of Florida Standard
Criminal Jury Instruction 3.6(f) governing self-defense and cases
interpreting that language. Based on this review, we conclude that
the self-defense standard in Florida includes a subjective
component as well as an objective component and approve the First
District’s conclusion in Mizell. 7 However, because the trial court
7. The State argues that the defense waived this issue. We reject the State’s waiver argument without further discussion.
- 17 - did not abuse its discretion in refusing to admit the expert PTSD
testimony, we conclude that the Second District was nevertheless
correct to affirm Oquendo’s conviction.
A. Section 776.012(2)
Section 776.012(2), Florida Statutes (2015), provides the
following requirements for self-defense:
A person is justified in using or threatening to use deadly force if he or she reasonably believes that using or threatening to use such force is necessary to prevent imminent death or great bodily harm to himself or herself or another or to prevent the imminent commission of a forcible felony.
(Emphasis added.)
Section 776.012(2) provides that a person’s use of deadly force
is justified as self-defense “if he or she reasonably believes” that the
use of that force is necessary to prevent imminent death or great
bodily harm. The plain text of the statute requires both that “he or
she . . . believe[d]” that the use of force was necessary (actual
subjective belief of the defendant) and that the belief was
“reasonabl[e]” (objective reasonable person standard). 40 C.J.S.
Homicide § 214 (2014) (“[W]hen self-defense has been asserted, the
defendant is entitled to have the jury consider the facts and
- 18 - circumstances known to the defendant (i.e., his or her subjective
belief), but those facts and circumstances must be balanced against
what a reasonable person would believe under the same or similar
circumstances, the ultimate test of ‘reasonableness’ being
objective.” (footnote omitted)). Thus, the First District was correct
in Mizell that there is both a subjective and objective component to
the self-defense standard.
B. Florida Standard Criminal Jury Instruction 3.6(f)
The language of the standard jury instruction on self-defense
also supports this conclusion. Florida Standard Criminal Jury
Instruction 3.6(f), which was included in the jury instructions at
Oquendo’s trial, provides that “[t]he use of deadly force is justifiable
if [the defendant] reasonably believed that the force was necessary
to prevent imminent death or great bodily harm to [himself].”
(Brackets in original.) The standard instruction further provides:
In deciding whether [the defendant] was justified in the use or threatened use of deadly force, you must consider the circumstances by which he was surrounded at the time the force or threat of force was used. The danger need not have been actual; however, to justify the use or threatened use of deadly force, the appearance of danger must have been so real that a reasonably cautious and prudent person under the same circumstances would have believed that the danger could
- 19 - be avoided only through the use of that force or threat of force. Based upon appearances, [the defendant] must have actually believed that the danger was real.
(Brackets removed; emphasis added.) Thus, the standard
instruction supports that the jury must find that the defendant had
an actual subjective belief that deadly force was necessary in self-
defense in addition to finding that that belief was reasonable. 8
Apart from Mizell, other Florida appellate opinions have
recognized that Florida’s self-defense standard includes both a
subjective and an objective component. In Raneri v. State, the First
District noted that in order to qualify as self-defense, “the slayer
must actually and reasonably believe that it is necessary to act in
order to save his own life or that of a member of his family from
death or great bodily harm in order to constitute justification.” 255
So. 2d 291, 294 (Fla. 1st DCA 1971) (citing Harris v. State, 104 So.
2d 739 (Fla. 2d DCA 1958)); see also Harris, 104 So. 2d at 743
(explaining that a person has a right to act in self-defense, “even to
8. This hybrid test, including both a subjective and objective component, is the most common among U.S. jurisdictions. 40 C.J.S. Homicide § 214 (2014) (“Generally, the standard of self- defense is a hybrid test, combining both an objective and subjective standard.”).
- 20 - the extent of taking life if he actually believes, and the
circumstances and surrounding conditions are such that a
reasonably cautious and prudent person would believe, danger of
death or great personal injury to be imminent, at the hands of
assailant”).
Likewise, in Filomeno v. State, the Fifth District Court of
Appeal held that the trial court erred in ruling inadmissible expert
testimony concerning the “fight or flight” response that the
defendant sought to introduce to show that “in some highly
stressful situations, an individual’s perception of danger may impel
them to ‘fight,’ when they perceive that they are being prevented
from ‘flight.’ ” 930 So. 2d 821, 822 (Fla. 5th DCA 2006). The Fifth
District found that at least some of the proffered evidence was not
diminished capacity evidence but rather “state-of-mind evidence,
analogous to battered spouse syndrome testimony that has been
approved many times.” Id. (citing Mizell, 773 So. 2d at 620). The
Fifth District noted that “[t]he standard jury instruction for self-
defense recognizes that a defendant’s perceptions of the
surrounding events are relevant when assessing the reasonableness
of the use of force in self-defense.” Id.
- 21 - In addition to Mizell and its progeny, the United States Court
of Appeals for the Fifth Circuit 9 in reviewing the habeas petition of a
defendant sentenced to life in prison in Florida noted that “to
establish self-defense under Florida law a person must show that
there existed reasonable grounds for him to believe that ‘he (was) in
imminent danger of death or great bodily injury’ and that he
actually held that belief when he acted.” Phillips v. Wainwright, 624
F.2d 585, 589 (5th Cir. 1980) (citing Raneri, 255 So. 2d at 294).
Even the Second District’s opinion below recognized that “a
defendant’s perceptions are relevant” in that “what he ascertained
with his senses constitutes the circumstances under which he was
required to assess” whether the use of force in self-defense was
necessary. Oquendo, 357 So. 3d at 218. However, the Second
District attempted to characterize this evidence as relevant only in
the context of the reasonable person standard—i.e., a reasonable
person in the circumstances as known to the defendant—while
denying the existence of a subjective component in the self-defense
9. Prior to the creation of the United States Court of Appeals for the Eleventh Circuit in 1981, the territorial jurisdiction of the Fifth Circuit included Florida.
- 22 - standard and determining that “a defendant’s misperceptions—[i.e.,]
his misunderstanding of reality as altered by a disorder such as
PTSD”—could not be relevant to determining the issue of self-
defense. Id. On the contrary, we find that because section
776.012(2) identifies both an objective reasonable person
component and a subjective component to self-defense, state-of-
mind evidence 10 such as PTSD evidence can be relevant to the
subjective component, even though it is irrelevant to the objective
component. Such evidence may tend to show that a defendant with
PTSD actually believed that he was in imminent danger. Our
finding is also supported by Florida Standard Criminal Jury
10. As noted in Mizell, evidence of battered spouse syndrome is also state-of-mind evidence that Florida courts have deemed admissible in self-defense cases. 773 So. 2d at 620. The Mizell opinion indicates that this evidence is relevant to what the defendant actually believed was necessary under the circumstances (the subjective component of self-defense), see id., while the Second District’s opinion below argues that battered spouse syndrome evidence shows what a reasonable person would believe was necessary under the circumstances of the battered spouse (the objective reasonable person test), Oquendo, 357 So. 3d at 219-20. Such evidence may be relevant to both the subjective and objective components of self-defense, but as the instant case does not concern battered spouse syndrome, further discussion of it is unnecessary to our determination here.
- 23 - Instruction 3.6(f), which instructs jurors to consider the “actual
belief” of the defendant.
Because we agree that the test for self-defense includes both a
subjective and objective component, we disapprove the Second
District’s holding in Oquendo that Florida’s self-defense law involves
only a reasonable person test and approve the First District’s
holding in Mizell.
C. Oquendo’s Conviction
Although we disapprove the Second District’s determination
that Florida’s self-defense law requires only an objective reasonable
person test and that evidence of a defendant’s subjective belief is
never relevant, we nevertheless approve the Second District’s
affirmance in this case. Here, Oquendo did not admit to
intentionally firing the gunshot that killed Cason. Instead, he
testified that the gun accidentally discharged as he was trying to
wrestle it away from Cason. Thus, his PTSD evidence would not be
relevant to whether he actually believed he needed to fire the gun to
defend himself since, according to his own testimony, the gun was
fired accidentally.
- 24 - Furthermore, although defense counsel stated that Oquendo
was not seeking to offer expert testimony concerning PTSD as
diminished capacity evidence, his explanation that it would be used
as “state-of-mind evidence” showing how “somebody that suffers
from that particular mental illness can react differently” sounds like
evidence of diminished capacity. For example, defense counsel at
one point argued that case law supported that, where PTSD is
involved, “the jury can get an instruction [o]n it because [the
defendant] may not react as well to a stressful situation as a normal
person.”
We also disapprove the Second District’s holding in Oquendo
that PTSD evidence is necessarily inadmissible diminished capacity
evidence, 357 So. 3d at 218-19, but we agree that defense counsel’s
arguments in this case indicate that the PTSD evidence was being
sought to establish diminished capacity. Diminished capacity
evidence is evidence of lowered mental capacity that is introduced
for the purpose of negating the specific intent requirement of a
particular charged offense. See Chestnut v. State, 538 So. 2d 820,
820 (Fla. 1989). Such evidence is generally inadmissible in Florida.
Id. at 824 (“To permit the defense of diminished capacity would
- 25 - invite arbitrary applications of the law because of the nebulous
distinction between specific and general intent crimes.”).
We reiterate that our holding today does not condone the use
of PTSD evidence to support an otherwise inadmissible claim of
diminished capacity. Where such state-of-mind evidence is relevant
to support a particular defense, the danger of a jury misapplying
the evidence as diminished capacity evidence may be prevented by
giving the jury “a limiting instruction that the expert testimony does
not tend to prove lack of specific intent but rather is relevant to
establish a particular defense.” Perry v. State, 256 So. 3d 888, 894
(Fla. 4th DCA 2018). The trial court in Mizell, for example, set forth
in its pretrial order five specific conditions that had to be met in
order for the defense to introduce the PTSD evidence, including the
defendant himself testifying and laying a predicate, the expert
witness being allowed only to lay out the defendant’s background
but not vouch for it, and the expert witness being prohibited from
offering an opinion on the validity of the defendant’s self-defense
claim. 773 So. 2d at 620.
However, here, the record supports the conclusion that the
trial court did not abuse its discretion in refusing to admit expert
- 26 - testimony on PTSD given defense counsel’s arguments suggesting
the central purpose was to show diminished capacity, and given
that the defendant did not lay the predicate. Thus, we approve the
Second District’s affirmance in this case.
III. Conclusion
We approve the First District’s decision in Mizell and hold that
the test for self-defense includes both a subjective and objective
component. Although we disapprove the Second District’s holding
that self-defense does not involve a subjective component, we
approve the Second District’s affirmance and ultimate outcome in
this case.
It is so ordered.
