    In the Supreme Court of Georgia
    Decided: February 21, 2023
    S22A1328. MIDDLEBROOKS v. THE STATE.
    ELLINGTON, Justice.
    After Marina Middlebrooks pleaded not guilty by reason of
    insanity to charges arising from the stabbing death of her daughter,
    Sky Allen, a jury found Middlebrooks guilty of murder and cruelty
    to children in the first degree.1 On appeal, Middlebrooks contends
    1  The crimes occurred on May 2, 2013. On July 10, 2013, a Columbia
    County grand jury returned an indictment charging Middlebrooks with malice
    murder (Count 1), felony murder predicated on aggravated assault (Count 2),
    and cruelty to children in the first degree (Count 3). On January 26, 2016,
    Middlebrooks was re-indicted on the same counts in Richmond County.
    Following a February 2016 trial, a Richmond County jury found Middlebrooks
    guilty on all three counts. On February 29, 2016, the trial court sentenced
    Middlebrooks to serve life in prison without parole on Count 1 and to serve 20
    years in prison on Count 3. The judgment indicated that Count 2 merged with
    Count 1, although it was actually vacated by operation of law. See Bradley v.
    State, 
    305 Ga. 857
    , 857 n.1 (
    828 SE2d 322
    ) (2019). Middlebrooks filed a timely
    motion for a new trial, which, through new counsel, she amended on May 27
    and October 5, 2020. Following a hearing on November 24, 2020, the trial court
    denied Middlebrooks’s motion for a new trial on August 19, 2021. Middlebrooks
    filed a timely notice of appeal, and the case was docketed in this Court for the
    August 2022 term and orally argued on November 8, 2022.
    that the trial court erred in allowing the State’s expert witness to
    testify as to what happens when a person is found not guilty by
    reason of insanity. In addition, Middlebrooks contends that “[t]he
    trial court erred in restricting the testimony of [her] diagnosing
    psychiatrist,” an employee of the Department of Veterans’ Affairs
    (“VA”), “without following the correct procedure” under federal
    regulations concerning the testimony of VA personnel in legal
    proceedings. In a related claim, Middlebrooks contends that her
    “trial counsel was ineffective in failing to object to the limitation of
    [the witness’s] testimony by the [f]ederal [g]overnment and the
    [p]rosecutor.” For the reasons explained below, we affirm.
    After indictment in Columbia County, where Sky’s dead body
    was discovered, the case was transferred to and re-indicted in
    Richmond County, based on Middlebrooks’s pretrial statements that
    placed the alleged criminal acts outside her Richmond County home.
    Middlebrooks filed a notice of intent to raise the issue that she was
    insane at the time of the acts charged against her. Before the trial
    began, the State and Middlebrooks entered into a stipulation that,
    2
    “[o]n May the 2nd, 2013, the Defendant, Marina Mae Middlebrooks,
    acting alone, caused the death of Sky Lyric Allen, by stabbing her in
    the neck. This act occurred in Richmond County, Georgia.” Because
    the parties stipulated that Middlebrooks killed her daughter, the
    primary issue the jury had to decide was Middlebrooks’s mental
    capacity at the time she committed the crimes, with the possible
    verdicts being not guilty, not guilty by reason of insanity, guilty but
    mentally ill, or guilty. 2 The jury was required to return a verdict of
    not guilty by reason of insanity if the jury found beyond a reasonable
    doubt that Middlebrooks committed the crimes charged in the
    2 OCGA § 17-7-131 (b) (1) provides:
    In all cases in which the defense of insanity, mental illness,
    or intellectual disability is interposed, the jury, or the court if tried
    by it, shall find whether the defendant is:
    (A) Guilty;
    (B) Not guilty;
    (C) Not guilty by reason of insanity at the time of the crime;
    (D) Guilty but mentally ill at the time of the crime, but the
    finding of guilty but mentally ill shall be made only in felony cases;
    or
    (E) Guilty but with intellectual disability, but the finding of
    intellectual disability shall be made only in felony cases.
    At the time of Middlebrooks’s trial, the fifth verdict option was “guilty but
    mentally retarded.” Since July 1, 2017, the fifth option has been “guilty but
    with intellectual disability.” See Ga. L. 2017, p. 471, § 3.

    indictment and also found by a preponderance of the evidence that
    she was legally insane at that time, that is, she did not have the
    mental capacity to distinguish between right and wrong in relation
    to the act.3 At the beginning of trial, the trial court read the parties’
    3  See OCGA §§ 16-3-2 (“A person shall not be found guilty of a crime if,
    at the time of the act, omission, or negligence constituting the crime, that
    person did not have the mental capacity to distinguish between right and
    wrong in relation to the act.”); 17-7-131 (a) (“For purposes of this Code section,
    the term . . . ‘[i]nsane at the time of the crime’ means meeting the criteria of
    Code Section 16-3-2 or 16-3-3. However, the term shall not include a mental
    state manifested only by repeated unlawful or antisocial conduct.”); 17-7-131
    (c) (1) (“The defendant may be found ‘not guilty by reason of insanity at the
    time of the crime’ if he or she meets the criteria of Code Section 16-3-2 or 16-3-
    3 at the time of the commission of the crime. If the court or jury should make
    such finding, it shall so specify in its verdict.”); Bowman v. State, 
    306 Ga. 97
    ,
    100 (1) (c) (
    829 SE2d 139
    ) (2019) (“In Georgia, a defendant is presumed to be
    sane and a defendant asserting an insanity defense has the burden to prove by
    a preponderance of the evidence that he was insane at the time the crime was
    committed.” (citation omitted)).
    We note that Middlebrooks’s counsel did not seek a jury instruction
    based on the other Code section referenced in OCGA § 17-7-131 (c) (1), OCGA
    § 16-3-3, which provides: “A person shall not be found guilty of a crime when,
    at the time of the act, omission, or negligence constituting the crime, the
    person, because of mental disease, injury, or congenital deficiency, acted as he
    did because of a delusional compulsion as to such act which overmastered his
    will to resist committing the crime.” At the charge conference, defense counsel
    stated, “[w]e are not claiming a justification delusion defense, [although] we do
    have a compulsive delusion[,]” because there was no “proof of justification.” See
    Buford v. State, 
    300 Ga. 121
    , 125 (1) (b) (
    793 SE2d 91
    ) (2016) (“When a
    delusional compulsion is the basis of an insanity defense, the delusion must be
    one that, if it had been true, would have justified the defendant’s actions.”
    (citation omitted)); 
    id.
     (holding that, because the defendant “could not
    articulate the particulars of any delusion from which he was suffering that
    would have justified his actions,” he could not “establish insanity pursuant to
    OCGA § 16-3-3”).
    4
    stipulation to the jury and instructed the jury that, based on the
    stipulations that had been entered into, Middlebrooks’s “plea of not
    guilty by reason of insanity frame[d] the issue that [the jury was]
    sworn and empaneled to try in this particular case.”
    The State presented the testimony of investigators and other
    witnesses as to the circumstances of the crimes. That uncontested
    evidence showed that, on May 2, 2013, a passerby saw
    Middlebrooks’s car swerve out of its lane on Ray Owens Road in
    Columbia County and then crash into a tree. The witness called 911.
    First responders found Middlebrooks in the driver’s seat. She was
    nude except for a sweatshirt and covered in blood. One first
    responder testified that Middlebrooks “did not appear to be fully
    conscious.” Middlebrooks told the first responders that “someone
    had done something” to her, but provided no details. To most of the
    first responders’ questions about what had happened to her, she
    answered, “I don’t know. I don’t remember.” While tending to
    Middlebrooks, first responders found her two-year-old daughter,
    Sky, dead on the car’s rear floor, underneath a pile of clothes. Sky
    5
    was also unclothed, covered in dried blood, and had a gaping stab
    wound to her neck. Her body had already cooled. A bloody pair of
    scissors lay in the front passenger seat. A medical examiner later
    determined that Sky had suffered multiple stab wounds, one of
    which severed a jugular vein, resulting in fatal blood loss. The
    wounds were consistent with having been created by the sharp edges
    of an opened pair of scissors. Middlebrooks had multiple puncture
    wounds and lacerations to her neck, face, chest, arms, wrists, and
    knee. Her neck wounds were severe enough to require intubation for
    a few days.
    After the State presented evidence of the circumstances of the
    crimes, Middlebrooks called several witnesses in support of her
    insanity defense. After being qualified as an expert, Dr. Geoffrey
    McKee, a board-certified criminal forensic psychologist, testified
    that he evaluated Middlebrooks in October 2014, when he spent 6
    hours, 25 minutes with her, and February 2016, when he spent an
    hour with her. In addition to administering psychological tests and
    interviewing Middlebrooks, Dr. McKee reviewed records of previous
    6
    evaluations and treatment of Middlebrooks, including a four-week
    hospitalization at the VA hospital in the summer of 2011, when she
    was diagnosed with “schizophreniform disorder” and with “post
    traumatic stress disorder,” arising from her 13 months in combat
    zones in Iraq. Dr. McKee testified that Middlebrooks was readmitted
    to the VA hospital for two weeks in February 2012 and diagnosed
    with “schizophrenia continuous, meaning that the symptoms were
    recurring on a . . . near daily basis,” and “schizophrenia paranoid
    type, which means that she had delusions of persecution, feelings
    that other people would hurt her even though there was no evidence
    of that.” For example, the records showed that Middlebrooks
    reported believing that other people wanted her to kill herself. Dr.
    McKee also reviewed the records from Middlebrooks’s five-day
    hospitalization following her arrest for Sky’s death and her
    hospitalization at East Central Regional Hospital in Augusta that
    began seven weeks after Sky’s death and lasted for about six weeks.
    In reviewing the records of the VA hospitalizations and the post-
    arrest hospitalizations, Dr. McKee looked for any indication in those
    7
    records that Middlebrooks was “malingering” – faking her
    symptoms – and he found none.
    Dr.   McKee   testified   about   his   own   examinations   of
    Middlebrooks and described some of the fixed delusions she
    reported, such as that “she could control and slow down time by
    moving her hands in a particular way.” Dr. McKee testified that
    Middlebrooks reported that, just before the crimes, she stripped
    herself and her daughter naked, even removing their earrings,
    “because she believed that to get to heaven she and her daughter
    would have to die” by their own hands, “but that they had to be
    naked because the clothes, including any jewelry, would block the
    spirits from leaving” their bodies. Dr. McKee administered several
    psychological tests to Middlebrooks, some of which are designed to
    detect malingering, and he found no evidence of malingering during
    the course of his own evaluation. Dr. McKee testified that
    “[c]ommand auditory hallucinations are not uncommon in persons
    with schizophrenia, but often with people who try to malinger
    schizophrenia, when they are charged with a crime will tell the
    8
    examiner that they had a command auditory hallucination” ordering
    them to commit the particular crime. Dr. McKee found it a
    significant indication that Middlebrooks was not malingering that,
    according to the records from her hospitalization in the days after
    the crimes, she “did not seize upon [a command hallucination] as a
    way of explaining away all that she had done.” Based on
    Middlebrooks’s history and his own evaluation, Dr. McKee
    diagnosed her with paranoid schizophrenia. In Dr. McKee’s opinion,
    at   the   time   of   the   crimes,   Middlebrooks   “suffered   from
    schizophrenia, a serious psychiatric disorder[,]” that “as a result of
    that disorder she did not have the mental capacity to know right
    from wrong[,]” and that “the delusional component of that . . .
    disorder overmaster[ed] her will to resist committing her offenses.”
    Dr. McKee testified that, in his more than 40-year career, he had
    evaluated more than 40 women who had killed one or more of their
    own children. Out of those 40 cases, Dr. McKee had found that only
    4 of those mothers, including Middlebrooks, were insane.
    Dr. Donna Schwartz-Watts, the chief psychiatrist for female
    9
    patients at Patrick B. Harris Psychiatric Hospital in Anderson,
    South Carolina, also testified as an expert witness. Dr. Schwartz-
    Watts evaluated Middlebrooks in February 2014, when she spent
    “over two hours” with her, and “saw her again a period of time later.”
    Like Dr. McKee, Dr. Schwartz-Watts reviewed records of
    Middlebrooks’s previous mental health treatment, including just
    after she killed Sky. Dr. Schwartz-Watts also reviewed statements
    by witnesses to the crash, Middlebrooks’s emergency treatment, and
    her   arrest;   examined    detention   records;   and   interviewed
    Middlebrooks’s mother and other witnesses. She found that
    Middlebrooks exhibited a common symptom of schizophrenia, a type
    of delusion called “ideas of reference,” and a very rare symptom,
    called “clanging.” She explained that, rather than expressing
    thoughts that were connected rationally, Middlebrooks would say
    words in a sequence that were related to each other only by “the
    sound of the words.” Dr. Schwartz-Watts described clanging as “one
    of the most severe and regressed forms of thought process, of
    connecting thoughts together,” and testified that it is a difficult
    10
    symptom to fake. In Dr. Schwartz-Watts’s opinion, Middlebrooks’s
    notes and drawings when she was intubated in the days after the
    crimes revealed signs of paranoid and delusional thinking. Dr.
    Schwartz-Watts testified that Middlebrooks reported that, in the
    days before she killed Sky, she was having recurrent delusional
    thoughts and compulsions that she and Sky “each had to commit
    suicide.” Middlebrooks said that she believed that God had given her
    and Sky a “green aura” that made them “special and unique” and
    that she and her daughter were being “persecuted” by people who
    “would mean them harm” because “they would want to have access
    to that gift[.]” Middlebrooks told Dr. Schwartz-Watts that, by
    committing suicide, she and Sky would “go to heaven so that they
    would be safe.” Dr. Schwartz-Watts testified that “morally
    [Middlebrooks] believed that she was doing God’s will” and that, for
    Sky to go to heaven, “[Sky] had to kill herself. [Middlebrooks] could
    not kill her daughter. So she took the scissors and had her daughter
    stab herself, helping her with the scissors. She stabbed her daughter
    thinking it’s the daughter’s hand[.]” Then Middlebrooks stabbed
    11
    herself and started driving to the marina, where she planned to
    finish killing herself. Middlebrooks explained to Dr. Schwartz-Watts
    that she was not completely naked when she crashed into the tree,
    because she put on a sweater after seeing a police officer stop
    another car and she did not want the police to stop her and prevent
    her from reaching the marina and completing her suicide. Based on
    Middlebrooks’s history of paranoid delusions and hallucinations, her
    psychotic behavior around the time of the crimes, and psychotic
    thinking that Dr. Schwartz-Watts personally observed during her
    evaluation sessions, she diagnosed Middlebrooks with acute
    schizophrenia. In Dr. Schwartz-Watts’s opinion, at the time of the
    offense, Middlebrooks did not “recognize[e] what she was doing was
    wrong,” but thought “she was doing the right thing” when she killed
    Sky.
    Dr. Donald Evans, a staff psychiatrist at the VA Medical
    Center in Augusta, testified about Middlebrooks’s two prior
    12
    hospitalizations in that facility. 4 He testified that in July 2011,
    Middlebrooks, an Iraq War veteran, “was admitted in a psychotic
    state, meaning, her reality was so distorted that she couldn’t trust
    her senses.” That hospitalization lasted approximately four weeks.
    During that time, Dr. Evans testified, Middlebrooks expressed that
    “[s]he was disturbed by what she described as people knowing what
    thoughts were in her head, putting thoughts in her head, or taking
    some of those thoughts out. And then she had some paranoid ideas
    that people were going to hurt her, and her physiology reflected
    that.” Middlebrooks was placed on antipsychotic medication that
    was “meant to help return thinking to cohesive functioning” and
    “quiet down” distorted thinking in the form of hallucinations or
    delusions. Dr. Evans read from a progress note in Middlebrooks’s
    chart, showing that the medications were given to treat
    “schizophreniform,” and he explained that “[s]chizophreniform is a
    diagnosis for a disturbance of perceptions that last for a period of
    4 As discussed in Division 2, infra, Evans testified as a fact witness only,
    not as an expert.
    13
    less than six months.” He testified that, “[i]f that disturbance goes
    beyond six months then it becomes schizophrenia, and both of those
    conditions I diagnosed.”
    Middlebrooks’s mother and father testified about their
    daughter’s mental breakdown in 2012, which resulted in the second
    hospitalization at the VA Hospital in Augusta. They found
    Middlebrooks walking aimlessly down the middle of a busy street,
    and she could not answer where she was going. When her father was
    driving her home, she tried to jump out of his truck. She told her
    father that he was the devil or “something evil” and screamed “don’t
    kill me.” Middlebrooks’s father testified that, after Middlebrooks
    returned from combat service in Iraq, she had changed – her face
    was “blank,” she “start[ed] forgetting things,” her “patience [was]
    shot,” and, when he looked in her eyes, “something was missing,
    something was gone.” Middlebrooks sometimes told her mother that
    she was hearing voices. In the weeks before Sky’s death,
    Middlebrooks’s   mother    thought    that   Middlebrooks    seemed
    withdrawn and that something was wrong with her. Middlebrooks’s
    14
    sister and brother-in-law testified, describing several incidents of
    Middlebrooks’s “belligerent” and bizarre behavior in the years
    between her return from Iraq in 2006 and Sky’s death in 2013,
    including having loud arguments with herself and accusing
    strangers of “talking bad about her and looking at her funny.” In
    early 2013, Middlebrooks told her sister that VA doctors diagnosed
    her with schizophrenia. Middlebrooks did not testify.
    The State presented the testimony of Middlebrooks’s cellmate
    at the Columbia County jail in November 2014, Kala Stewart, as to
    statements Middlebrooks made while awaiting trial. Stewart
    testified that Middlebrooks told her that “she killed her child before
    she left the house, her driveway,” and “she did it out of spite of her
    boyfriend.” Stewart testified that Middlebrooks told her that “her
    lawyer was going for mental illness” as a defense, but Middlebrooks
    told Stewart that “she [was not] mentally ill.” Middlebrooks told
    Stewart that she did not think her case was going well.
    In addition, the State presented expert testimony to rebut the
    testimony of Middlebrooks’s expert witnesses that they found no
    15
    evidence of malingering, either in Middlebrooks’s past mental
    health records or in their own evaluations. Dr. Michael Vitacco, after
    being qualified as an expert in forensic psychology, testified that he
    evaluated Middlebrooks at the East Central Regional Hospital,
    where he serves as a licensed clinical psychologist, over the course
    of 40 days in June and July 2013, beginning seven weeks after Sky’s
    death. In addition to formally interviewing Middlebrooks three
    times and giving her psychological tests, meetings lasting a total of
    3 hours and 20 minutes, Dr. Vitacco spoke with her briefly
    approximately 20 times over her 40-day stay. He also communicated
    with her treating psychiatrist and other caregivers who interacted
    with Middlebrooks for extended periods daily. After Middlebrooks
    returned to the jail, he and a colleague prepared a Criminal
    Responsibility Evaluation report and a Competency to Stand Trial
    Evaluation report.
    In Dr. Vitacco’s opinion, other practitioners’ diagnosis of
    schizophrenia was not supported by the evidence, one reason being
    that the records showed that Middlebrooks’s symptoms improved
    16
    during each hospitalization much more quickly than would typically
    happen in cases of acute schizophrenia. Dr. Vitacco testified that,
    during interviews with him, Middlebrooks reported hearing voices
    and behaved consistently with that symptom, but she would behave
    “quite differently,” appearing to be unaffected by hallucinations,
    when she was “away from the people who were interviewing her.”
    Dr. Vitacco noted that, according to Middlebrooks’s mental health
    records, she reported paranoid delusions that “people were out to get
    her,” but “at no point” before she killed Sky “did she endorse a
    delusion consistent with killing her child.” He also found it
    significant that Middlebrooks never reported any religious delusions
    until after she killed Sky and was being evaluated for criminal
    responsibility, at which point she reported a religious delusion that
    she was on a mission from God to help Sky go to heaven. Dr. Vitacco
    testified that Middlebrooks’s description of the events “changed
    dramatically” and evolved from telling first responders that she had
    no recollection of the entire event, to telling detectives that nothing
    happened and Sky was still alive, and then, “[f]ast forward just eight
    17
    weeks and she had a perfect recollection, once she arrived at the
    hospital, of everything that happened in that car, including being
    able to describe the last minutes of her daughter’s life.” Dr. Vitacco
    believed that, after being given the Structured Interview of Reported
    Symptoms test, Middlebrooks falsely reported a version of some of
    the specific hallucinations that were questions on the test. He
    testified that she reported “a slew of new symptoms” after she killed
    Sky, “each one self-serving to justify the death of her daughter[,]”
    but she did not display the behavioral “signs” of someone
    experiencing   the   reported   symptoms.     Staff   members    saw
    Middlebrooks “greeting [other patients] warmly” and laughing with
    them – she was even “voted vice-president of [her] unit because her
    peers liked her so much” – and she followed hospital rules and
    behaved appropriately in classes and group sessions. Dr. Vitacco
    testified that, “on several occasions[,]” after a class or group,
    Middlebrooks “would approach the group leader” and ask “specific
    questions about the insanity defense” and “how . . . one go[es] about
    it.” During the last week of her 40-day stay at the hospital,
    18
    Middlebrooks told her treating psychiatrist that she was “feeling
    hopeful . . . about the possibility of building an NGRI case.”
    Dr. Vitacco defined malingering as “the intentional production
    of symptoms in order to basically get out of something,” such as, in
    the criminal justice context, “to get out of going to prison or going to
    trial.” After reviewing evidence about Middlebrooks’s behavior in
    the few days surrounding Sky’s death, including a videotaped police
    interview, reviewing the VA records, personally interviewing and
    observing Middlebrooks, and administering tests designed, in part,
    to detect malingering, Dr. Vitacco concluded that Middlebrooks was
    “retrospectively malingering,”     that   is, feigning    having had
    symptoms at the time of Sky’s death in order to avoid criminal
    responsibility for the death of her daughter.
    Based on the totality of the evidence Dr. Vitacco reviewed, his
    professional opinion was that, “when [Middlebrooks] killed her
    daughter[,]” she “was not mentally ill[;]” specifically, she was not
    “psychotic” or suffering from “schizophrenia[,]” which is a “thought
    disorder.” Dr. Vitacco testified that Middlebrooks was diagnosed,
    19
    during her hospitalization at East Central Regional Hospital, with
    post-traumatic stress disorder and with “a series of personality
    disorders[,]” which are “maladaptive traits” that are “not considered
    . . . disorder[s] of thought or mood that substantially impair[ ] one’s
    judgment, one’s behavior, one’s ability to recognize reality[.]” In
    terms   of   personality   disorders,   Dr.   Vitacco   testified   that
    Middlebrooks was diagnosed with “borderline personality disorder”
    and “adjustment disorder.” Despite these diagnoses, in Dr. Vitacco’s
    expert opinion, when Middlebrooks killed her daughter, “she was
    very aware of right from wrong” and “was very aware that murder
    was against the law, both morally wrong and legally wrong.” He
    testified that he did not believe that Middlebrooks “was experiencing
    a delusional compulsion that overmastered her will” at the time of
    the crime and that, even if he did believe her, the nature of the
    delusion she reported would not have justified the act of killing her
    daughter. In Dr. Vitacco’s opinion, Middlebrooks was simply “angry
    and she took it out on her two-year-old child.” Asked if he had “any
    personal stake in the outcome of this case,” Dr. Vitacco replied that
    20
    he had no personal stake in the case and described himself as “a
    state employee and a psychologist” who was not “paid by the
    prosecution or the defense” and was “simply a [j]udge’s witness.”
    At the end of Dr. Vitacco’s direct testimony, the prosecutor
    asked him “what happens when a person is found not guilty by
    reason of insanity?” Defense counsel did not object before Dr. Vitacco
    responded that the person “would come to our hospital for a period
    of 30 days. And then we would evaluate that individual . . . to
    determine if they were mentally ill . . . and dangerous to themselves
    or others. And then we would have a hearing in 30 days to determine
    if they could be released[, as required by] state law[.]” The
    prosecutor asked, “[b]y law, if that person is not a danger to themself
    or others and is not suffering from a mental illness, what is the
    [c]ourt obligated to do?” Dr. Vitacco answered, “[A]ccording to the
    Supreme Court[, the trial court would] be obligated to release that
    individual.” Middlebrooks’s counsel objected to “this man giving a
    legal opinion” and moved to strike the testimony, arguing that
    “Georgia law tells us what the law is. [Such a person does not] get
    21
    out until you say they get out. . . . [T]he [j]udge gives the law . . . not
    the State’s witness.” The trial court overruled the objection and
    declined to strike the testimony.
    1. Middlebrooks contends that the trial court abused its
    discretion in overruling her objection to Dr. Vitacco’s testimony
    about what happens after a jury finds a criminal defendant not
    guilty by reason of insanity and in denying her motion to strike the
    testimony. She contends that the testimony constituted improper
    legal opinion testimony and that the law should have come only from
    the judge. In addition, Middlebrooks argues that Dr. Vitacco’s
    testimony paraphrased parts of OCGA § 17-7-131, pertaining to
    evaluation and commitment following a verdict of not guilty by
    reason of insanity, information that should not have been conveyed
    to the jury, and that his paraphrase was incomplete and misleading.
    Middlebrooks argues that Dr. Vitacco’s reference to those
    aspects of the law was especially harmful because he described
    himself as the “[j]udge’s witness” and because he implied that he
    personally would be evaluating her after verdict. Because Dr.
    22
    Vitacco had testified that he had already found that Middlebrooks
    was merely malingering and not mentally ill, Middlebrooks
    contends that the testimony improperly encouraged the jury to
    believe that, if the jury returned a verdict of not guilty by reason of
    insanity, the trial court would have no choice but to release her
    immediately after a 30-day post-trial evaluation. And she argues
    that the trial court’s instruction about the consequences of a verdict
    of not guilty by reason of insanity did not correct and override Dr.
    Vitacco’s misleading paraphrase of OCGA § 17-7-131, because the
    court’s instruction did not directly contradict Dr. Vitacco’s statement
    and could be understood by the jury as complementary with that
    testimony. She also argues that the trial court’s instruction that the
    jury is not to concern itself with punishment did not alleviate the
    harm caused by the statement because commitment after a not
    guilty by reason of insanity verdict is not in the nature of
    punishment and therefore the instruction about the jury not
    concerning itself with punishment did not apply.
    When an accused pleads not guilty by reason of insanity at the
    23
    time of the crime, the Criminal Procedure Code requires the trial
    court to instruct the jury in specific and limited terms regarding the
    consequences of each potential verdict. 5 See OCGA § 17-7-131 (b) (3).
    One of these instructions is that, “should you find the defendant not
    guilty by reason of insanity at the time of the crime, the defendant
    5  OCGA § 17-7-131 (c) provides in pertinent part:
    In all criminal trials in any of the courts of this state wherein
    an accused shall contend that he or she was insane, mentally ill,
    or intellectually disabled at the time the act or acts charged
    against him or her were committed, the trial judge shall instruct
    the jury that they may consider, in addition to verdicts of “guilty”
    and “not guilty,” the additional verdicts of “not guilty by reason of
    insanity at the time of the crime,” “guilty but mentally ill at the
    time of the crime,” and “guilty but with intellectual disability.”
    See Foster v. State, 
    283 Ga. 47
    , 49 (2) (
    656 SE2d 838
    ) (2008) (“When a defense
    of insanity has been interposed, OCGA § 17-7-131 (c) requires that the jury be
    instructed to consider all five verdict options set forth therein. The failure to
    charge on all five options is harmless error if there is no evidence to support
    the verdict option or options omitted.”); see also Durrence v. State, 
    287 Ga. 213
    ,
    216 n.4 (
    695 SE2d 227
    ) (2010) (Recognizing the clear legal distinctions between
    being insane at the time of the crime and being mentally ill or mentally
    retarded, which was the fifth verdict option at the time, each of which requires
    different forms of proof, “and their correlating similarities, OCGA § 17-7-131
    (c) requires that the jury be instructed to consider all five verdict options set
    forth therein when a defense of insanity is raised.”). In this case, there was no
    evidence of any mental retardation or intellectual disability, and neither the
    trial court’s jury charge nor the verdict form included the verdict option of
    “guilty but mentally retarded.” Although OCGA § 17-7-131 (c) requires that
    the jury be instructed to consider all five verdict options set forth in the statute,
    Middlebrooks does not claim that it was error to omit the fifth option in her
    case.

    This Court has explained that the jury instructions
    required by OCGA § 17-7-131 (b) (3) create a limited
    exception to the general rule proscribing consideration of
    6 In full, OCGA § 17-7-131 (b) (3) provides:
    (3) In all cases in which the defense of insanity, mental
    illness, or intellectual disability is interposed, the trial judge shall
    charge the jury, in addition to other appropriate charges, the
    following:
    (A) I charge you that should you find the defendant not guilty
    by reason of insanity at the time of the crime, the defendant will
    be committed to a state mental health facility until such time, if
    ever, that the court is satisfied that he or she should be released
    pursuant to law.
    (B) I charge you that should you find the defendant guilty
    but mentally ill at the time of the crime, the defendant will be
    placed in the custody of the Department of Corrections which will
    have responsibility for the evaluation and treatment of the mental
    health needs of the defendant, which may include, at the discretion
    of the Department of Corrections, referral for temporary
    hospitalization at a facility operated by the Department of
    Behavioral Health and Developmental Disabilities.
    (C) I charge you that should you find the defendant guilty
    but with intellectual disability, the defendant will be placed in the
    custody of the Department of Corrections, which will have
    responsibility for the evaluation and treatment of the mental
    health needs of the defendant, which may include, at the discretion
    of the Department of Corrections, referral for temporary
    hospitalization at a facility operated by the Department of
    Behavioral Health and Developmental Disabilities.
    25
    the consequences of a guilty verdict. This exception
    protects the defendant’s right to an impartial verdict by
    correcting any misconceptions jurors may have that a
    verdict of not guilty by reason of insanity, guilty but
    mentally ill, or guilty but with intellectual disability
    would result in the defendant’s immediate release (as
    does a verdict of not guilty). . . . Once the jury
    understands the nature of these particular verdicts, it can
    focus solely on the mental condition of the defendant and
    decide that issue free from concerns about whether and
    how the defendant might be punished.
    Id. at 593 (2) (b) (citation and punctuation omitted).
    In this case, Dr. Vitacco introduced aspects of the consequences
    of a verdict of not guilty by reason of insanity that appear in parts
    of OCGA § 17-7-131 and the statutory criteria for involuntary civil
    commitment 7 that are not pertinent to the issues to be decided by
    7 OCGA § 17-7-131 (d) provides:
    Whenever a defendant is found not guilty by reason of insanity at
    the time of the crime, the court shall retain jurisdiction over the
    person so acquitted and shall order such person to be detained in
    a state mental health facility, to be selected by the Department of
    Behavioral Health and Developmental Disabilities, for a period not
    to exceed 30 days from the date of the acquittal order, for
    evaluation of the defendant’s present mental condition. Upon
    completion of the evaluation, the proper officials of the mental
    health facility shall send a report of the defendant’s present
    mental condition to the trial judge, the prosecuting attorney, and
    the defendant’s attorney, if any.
    OCGA § 17-7-131 (e) (1) provides:
    26
    the jury. See OCGA § 17-7-131 (b) (1). And he did so in a way that
    could have been misleading. Specifically, Dr. Vitacco referred to an
    evaluation at “our hospital,” while the statute provides that a person
    found not guilty of a crime by reason of insanity would be detained
    at a state mental health facility chosen by the Department of
    Behavioral Health and Developmental Disabilities. See OCGA § 17-
    7-131 (d). More importantly, his statement that, after 30 days’
    After the expiration of the 30 days’ evaluation period in the
    state mental health facility, if the evaluation report from the
    Department of Behavioral Health and Developmental Disabilities
    indicates that the defendant does not meet the inpatient
    commitment criteria of Chapter 3 of Title 37 or Chapter 4 of Title
    37, the trial judge may issue an order discharging the defendant
    from custody without a hearing.
    After a verdict of not guilty by reason of insanity, the trial judge
    determines under specified procedures whether the defendant meets the
    statutory inpatient-commitment criteria. See OCGA §§ 37-3-1 (9.1)
    (“‘Inpatient’ means a person who is mentally ill and . . . [w]ho presents a
    substantial risk of imminent harm to that person or others, as
    manifested by either recent overt acts or recent expressed threats of
    violence which present a probability of physical injury to that person or
    other persons . . . and . . . [w]ho is in need of involuntary inpatient
    treatment.”); 37-3-83 (g) (If, after a specified process, the designated
    medical officer determines that an involuntarily hospitalized person “is
    not a person who has mental illness requiring involuntary treatment,
    the person shall be immediately discharged from involuntary
    hospitalization[.]”); 37-3-85 (providing for regular review of service plans
    for patients receiving involuntary inpatient treatment and for
    modification of plans, including by discharge, as medically appropriate).
    27
    evaluation, “we would have a hearing” to determine whether the
    person was legally entitled to be released obscured the fact that the
    trial court would “retain jurisdiction” over Middlebrooks, OCGA §
    17-7-131 (d), 8 and that she could only be discharged from
    involuntary commitment by order of the trial court in accordance
    with procedures specified in the Code section. See OCGA § 17-7-131
    (f).9
    See also OCGA § 17-7-131 (e) (4) (If, after the 30-day evaluation of the
    8
    defendant’s mental condition and a hearing, if ordered, under OCGA § 17-7-
    131 (d), “the judge determines that the defendant meets the [statutory]
    inpatient commitment criteria . . . , the judge shall order the defendant to be
    committed to the Department of Behavioral Health and Developmental
    Disabilities to receive involuntary treatment . . . or to receive services” under
    the Mental Health Code.).
    9 OCGA § 17-7-131 (f) provides:
    A defendant who has been found not guilty by reason of
    insanity at the time of the crime and is ordered committed to the
    Department of Behavioral Health and Developmental Disabilities
    under subsection (e) of this Code section may only be discharged
    from that commitment by order of the committing court in
    accordance with the procedures specified in this subsection:
    (1) Application for the release of a defendant who has been
    committed to the Department of Behavioral Health and
    Developmental Disabilities under subsection (e) of this Code
    section upon the ground that he does not meet the civil
    commitment criteria under Chapter 3 of Title 37 or Chapter 4 of
    Title 37 may be made to the committing court, either by such
    defendant or by the superintendent of the state hospital in which
    the said defendant is detained;
    (2) The burden of proof in such release hearing shall be upon
    28
    Closing arguments were not transcribed, and we cannot
    discern whether either side’s argument clarified Dr. Vitacco’s
    response to the question.10 By the same token, we cannot assume
    that the prosecutor’s argument amplified the implication that
    within a short period the trial court might be obligated to order that
    Middlebrooks be released. In the trial court’s final charge to the jury,
    the court instructed the jury as required by OCGA § 17-7-131 (b) (3)
    regarding the consequences of each of the possible verdicts,
    including that, if the jury should find Middlebrooks not guilty by
    reason of insanity, she would be committed until such time, if ever,
    the applicant. The defendant shall have the same rights in the
    release hearing as set forth in subsection (e) of this Code section;
    and
    (3) If the finding of the court is adverse to release in such
    hearing held pursuant to this subsection on the grounds that such
    defendant does meet the inpatient civil commitment criteria, a
    further release application by the defendant shall not be heard by
    the court until 12 months have elapsed from the date of the
    hearing upon the last preceding application. The Department of
    Behavioral Health and Developmental Disabilities shall have the
    independent right to request a release hearing once every 12
    months.
    10 At the hearing on Middlebrooks’s motion for a new trial, her appellate
    counsel asked her trial counsel, “During the closing argument did you discuss
    the effect of a not guilty by reason of insanity verdict?” Her trial counsel did
    not answer “yes” or “no” but only stated that he did not remember everything
    he said in closing argument.
    29
    the court was satisfied that she should be released pursuant to law.
    The trial court’s jury charge did not address the 30-day evaluation
    procedure under OCGA § 17-7-131 (d) and the statutory criteria for
    involuntary civil commitment that Dr. Vitacco referenced.
    We   can   see   that   Dr.   Vitacco’s   testimony   about   the
    consequences of a verdict of not guilty by reason of insanity, if
    credited by jurors as a correct statement of applicable law, could
    have reinforced, rather than corrected, any misconceptions jurors
    may have had that only a guilty verdict would prevent
    Middlebrooks’s nearly immediate release. If taken in this light, Dr.
    Vitacco’s testimony undermined an essential purpose of OCGA § 17-
    7-131. See Foster, 
    306 Ga. at 593
     (2) (b). Given the narrow focus of
    the statutorily prescribed jury instructions, the State should not
    have elicited such extraneous testimony. Assuming the trial court
    erred in allowing the testimony to stand, we must consider whether
    the error was harmless to determine if a new trial is warranted. See
    Jones v. State, 
    315 Ga. 117
    , 123 (4) (
    880 SE2d 509
    ) (2022)
    (“Erroneous evidentiary rulings are subject to a harmless-error
    30
    test.”). The harmless-error test applicable in this case is that for
    nonconstitutional error.
    A nonconstitutional error is harmless if the State shows
    that it is highly probable that the error did not contribute
    to the verdict, an inquiry that involves consideration of
    the other evidence heard by the jury. In determining
    whether the error was harmless, we review the record de
    novo, and we weigh the evidence as we would expect
    reasonable jurors to have done so as opposed to viewing it
    all in the light most favorable to the jury’s verdict.

    incapable of distinguishing between right and wrong regarding the
    particular acts charged. See Bowman v. State, 
    306 Ga. 97
    , 100 (1) (c)
    (
    829 SE2d 139
    ) (2019). As recounted above, opinion evidence given
    by Drs. McKee and Schartz-Watts supported a finding that
    Middlebrooks’s mental illness of acute schizophrenia with delusions
    rendered her incapable of distinguishing between right and wrong
    with regard to killing Sky. On the other hand, Dr. Vitacco’s opinion
    evidence supported the contrary finding that Middlebrooks was
    mentally capable of distinguishing between right and wrong
    regarding the act of fatally stabbing her daughter. His testimony
    included detailed descriptions of the distinctions between disorders
    of thought – disorders, such as schizophrenia, that may rob a person
    of the mental capacity to distinguish right from wrong at the time of
    a criminal offense – and other mental health conditions that do not
    typically have that effect. Dr. Vitacco’s expert opinion that
    Middlebrooks did not have a mentally incapacitating thought
    disorder when she fatally stabbed Sky was based in part on his
    personal observation that Middlebrooks’s behavior was often
    32
    inconsistent with the symptoms she reported. In addition, he
    testified that he learned from hospital staff members that
    Middlebrooks actively sought information about how to “go about”
    and “build” an insanity defense. The evidence that Dr. Vitacco
    formed   his   opinions   after   interacting   with   and   observing
    Middlebrooks much closer in time to the crimes and on many more
    occasions than had Drs. McKee and Schwartz-Watts is a factor in
    assessing the weight of Dr. Vitacco’s expert opinion that
    Middlebrooks was faking mental illness to avoid criminal
    responsibility for killing her daughter. Another factor is evidence,
    introduced through the testimony of Middlebrooks’s cellmate, that
    Middlebrooks denied being mentally ill, despite her lawyer’s plan to
    present a mental illness defense, and admitted that she killed her
    daughter out of spite.
    The State’s burden under the applicable harmless-error test –
    showing that “it is highly probable that the error did not contribute
    to the verdict” – is a heavy one. Even so, to overturn the jury’s
    verdicts on the basis of Dr. Vitacco’s improper testimony, there must
    33
    be more than a theoretical possibility that the error contributed to
    the verdicts. In assessing nonconstitutional error, we do not look to
    a single aspect of Dr. Vitacco’s testimony, divorced from the context
    of the entire trial. We consider all of the evidence, and we weigh the
    evidence as we would expect reasonable jurors to have done. See
    Jones, 315 Ga. at 122 (4). 12 Having reviewed all of the evidence de
    novo and weighed it as we would expect reasonable jurors to have
    done, we conclude that it is highly likely that Dr. Vitacco’s brief
    testimony about the general consequences of a verdict of not guilty
    by reason of insanity was not an important factor for the jury
    compared to the substantial evidence that Middlebrooks had the
    mental capacity to distinguish right from wrong in killing Sky.
    Because it is highly probable that the trial court’s ruling on
    Middlebrooks’s objection and motion to strike the testimony did not
    contribute to the verdict, a new trial is not warranted. See Brookins
    12See also Johnson, 
    238 Ga. at 61
     (Even an error that is “relevant to the
    issues in dispute, not cumulative of other evidence, not beneficial to the
    defendant[,] and uncorrected by the trial court . . . may nevertheless be
    harmless in the context of the entire case.”).

    v. State, 
    315 Ga. 86
    , 99 (5) (
    879 SE2d 466
    ) (2022).
    2. (a) Middlebrooks contends that “the trial court erred in
    restricting” Dr. Evans’s testimony to non-expert matters “without
    following    the   correct    procedure”     under    federal    regulations
    concerning the testimony of VA personnel in legal proceedings. 13
    This claim fails because Middlebrooks failed to preserve any error
    in this regard for ordinary appellate review and she failed to show
    plain error.
    The record shows that, at the beginning of Middlebrooks’s
    presentation of evidence, an assistant United States Attorney
    accompanied Dr. Evans to court and advised the trial court that
    federal law required approval from the federal government anytime
    13 See 
    38 CFR §§ 14.800
     through 14.810, establishing policy, assigning
    responsibilities, and prescribing procedures with respect to the testimony of
    VA personnel and production of department records in federal, state or other
    legal proceedings. Section 14.808 (a) provides in relevant part: “VA personnel
    shall not provide, with or without compensation, opinion or expert testimony
    in any legal proceedings concerning official VA information, subjects or
    activities, except on behalf of the United States or a party represented by the
    United States Department of Justice[,]” absent official authorization by the
    responsible VA official. Section 14.804 sets out the types of factors VA
    personnel responsible for making the decision whether to authorize the
    disclosure of VA records or information or the testimony of VA personnel
    should consider.
    35
    a federal employee is called as a witness in state court. The federal
    attorney reported that, after defense counsel requested that Dr.
    Evans testify, the VA Office of General Counsel authorized him to
    testify within boundaries, specifically that Dr. Evans could testify
    about   his   personal    observations    of   Middlebrooks,     about
    conversations he had with her, and about the contents of her medical
    records, but he could not serve as an expert witness or answer
    hypothetical questions. The prosecutor then argued that, “if [Dr.
    Evans] can’t testify as an expert witness[,] then he can’t render an
    opinion as to his diagnosis [of Middlebrooks] back in 2011 and 2012.”
    Initially, the prosecutor framed an objection based on relevance,
    asserting, if Dr. Evans could not give expert opinion testimony, then
    none of his testimony would be relevant. Defense counsel stated that
    he would not be asking for “a present diagnosis,” but for “a historical
    diagnosis,” and argued that such testimony would not constitute
    expert testimony.
    In the ensuing colloquy among the trial court and counsel, the
    court asked if defense counsel had any legal authority “that
    36
    support[ed] what [the defense] wanted to go into [during his
    examination of Dr. Evans] based on the restrictions that have been
    placed on [his] testimony.” Defense counsel responded that he
    intended to ask Dr. Evans about “the nature of [Middlebrooks’s]
    hospitalization[,] . . . why she was in the hospital[,] . . . how long she
    was in the hospital, and whether or not she was confined in the
    hospital.” After a recess, defense counsel, “in an effort to compromise
    this issue[,] . . . agree[d] not to ask [Dr. Evans] about his diagnosis”
    of Middlebrooks. Defense counsel described Dr. Evans as an
    “essential” witness, because he had been Middlebrooks’s caretaker
    in the VA mental hospital twice in the years before this crime
    occurred[,]” and argued that if he was prohibited from testifying
    Middlebrooks would be “deprived of the right of compulsory process
    and [her] constitutional rights under both the State and Federal
    constitution[s], [her] Sixth Amendment rights.” Softening the
    State’s earlier position, the prosecutor stated, “I’m not objecting to
    him testifying.” The trial judge stated, “I’m not going to . . . prohibit
    him from testifying, but based on restrictions that are in place it
    37
    does not appear that he can render a diagnosis.” Defense counsel
    responded, “I understand.” The prosecutor advised that he would
    object “based on [a lack of] foundation” to any question “that call[ed]
    for an opinion[,] . . . including the diagnosis[,]” because such an
    opinion could only “be rendered by an expert[.]” Defense counsel
    responded, “[w]e can handle that,” the court summoned the jury, and
    Dr. Evans took the stand.
    Assuming without deciding that the trial court affirmatively
    ruled that Dr. Evans was prohibited from “render[ing] a diagnosis,”
    the record establishes that the defense ultimately withdrew any
    challenge to such ruling. Without preservation of error as provided
    in OCGA § 24-1-103, we review an evidentiary ruling only for plain
    error pursuant to OCGA § 24-1-103 (d). See Ellington v. State, 
    314 Ga. 335
    , 343 (3) (
    877 SE2d 221
    ) (2022); Lofton v. State, 
    309 Ga. 349
    ,

    306 Ga. 747
    , 749 (2)
    (
    833 SE2d 122
    ) (2019). To establish plain error, Middlebrooks “must
    point to an error that was not affirmatively waived,” and that “error
    must have been clear and not open to reasonable dispute, must have
    38
    affected [her] substantial rights, and must have seriously affected
    the fairness, integrity or public reputation of judicial proceedings.”
    Ellington, 314 Ga. at 343 (3) (citation, punctuation, and footnote
    omitted).
    “For purposes of plain error review, an affirmative waiver is
    the intentional relinquishment or abandonment of a known right.”
    Griffin v. State, 
    309 Ga. 860
    , 865 (2) (
    849 SE2d 191
    ) (2020) (citation
    and punctuation omitted). The record shows that the defense
    invoked known rights, then proposed a resolution to the parties’
    evidentiary     dispute    that    involved    voluntarily   curtailing
    Middlebrooks’s assertion of those rights. The transcript of the
    colloquy before Dr. Evans testified shows that defense counsel opted
    to proceed with Dr. Evans’s testimony, with the latitude to question
    him, without drawing an objection by the State, about the facts of
    Middlebrooks’s hospitalizations with the sole limitation that he
    could not elicit testimony that Dr. Evans had diagnosed
    Middlebrooks with schizophrenia – an opinion that was reflected in
    the   medical    records   and    referenced   in   the   testimony   of
    39
    Middlebrooks’s two expert witnesses. In addition, at the hearing on
    Middlebrooks’s motion for a new trial, her trial counsel testified that
    he had previous experience with “forcing an expert witness who did
    not want to appear” as an expert to testify, that witness “made [him]
    ‘wish’” he had not compelled the witness to testify, and he “didn’t
    want to have that situation with Dr. Evans.” Thus, Middlebrooks
    intentionally relinquished any claim that the trial court erred in
    limiting the scope of Dr. Evans’s testimony, and this claim of error
    fails at the first stage of plain-error review. See Washington v. State,
    
    312 Ga. 495
    , 499 (1) (
    863 SE2d 109
    ) (2021); Griffin, 309 Ga. at 864-
    866 (2); see also State v. Herrera-Bustamante, 
    304 Ga. 259

    (b) (
    818 SE2d 552
    ) (2018) (“We need not analyze all of the elements
    of [the plain-error] test when, as in this case, the defendant has
    failed to establish one of them.”).
    (b) In a related claim of error, Middlebrooks contends that her
    “trial counsel was ineffective in failing to object to the limitation of
    Dr. Evan[s]’s testimony by the [f]ederal government and the
    [p]rosecutor.” Specifically, she criticizes her counsel’s conduct in
    40
    “ultimately consent[ing] to limiting his questions of Dr. Evans.” In
    addition, Middlebrooks avers that her “[t]rial counsel expressed
    ignorance of the federal rule governing VA testimony,” and she
    argues that, “[h]ad he consulted the regulation governing expert
    testimony of VA witnesses, he would have seen the procedure that
    needed to be followed by either himself or the [c]ourt.” In another
    section of her brief, Middlebrooks avers that defense counsel did not
    “request the Department of Veterans Affairs to allow Dr. Evans to
    testify as an expert. This is even though the factors listed in [the
    applicable federal regulation] would have likely been met.” She
    contends that “the diagnosis of her mental illness was hampered by
    the exclusion of her primary diagnosing physician” and that, as a
    result, “[t]he accusation of recent fabrication was left hanging over
    the trial.” Middlebrooks contends that “[t]he error of trial counsel
    was so prejudicial that it most likely changed the outcome of the
    trial.” To prevail on a claim of ineffective assistance of counsel, the
    appellant “must show that          his   lawyer’s   performance   was
    constitutionally deficient and that he suffered prejudice as a result.”

    , 687 (III) (104
    SCt 2052, 80 LE2d 674) (1984). If the appellant “fails to prove one
    element of this test, we need not address the other element.” Mahdi

    punctuation omitted).
    First, Middlebrooks’s claims that her counsel failed to seek
    permission from the VA to allow Dr. Evans to testify as an expert
    and that he expressed ignorance at trial of the federal rule governing
    VA testimony are belied by the record. The representative of the VA
    informed the trial court that, in advance of the trial, Middlebrooks’s
    counsel requested approval from the VA for Dr. Evans to testify and
    that the VA authorized him to testify within boundaries the VA set.
    The record shows at most that counsel was caught off guard by the
    prosecutor’s initial, later-abandoned objection to Dr. Evans’s
    testifying at all if he was not permitted to testify as to his
    42
    diagnoses.14
    As to counsel’s agreement not to ask Dr. Evans about his
    diagnoses, we consider the second prong of Strickland first. To show
    prejudice, the appellant “must show that there is a reasonable
    probability that, but for counsel’s unprofessional errors, the result
    of the proceeding would have been different. A reasonable
    probability is a probability sufficient to undermine confidence in the
    outcome.” Strickland, 
    466 U. S. at 694
     (III) (B). Although defense
    counsel failed to object to the limitations placed on Dr. Evans’s
    testimony, counsel presented two expert witnesses, who testified
    about her diagnoses, the severity of her symptoms, and her mental
    illness’s effect on her ability to distinguish right from wrong when
    she killed Sky. Middlebrooks’s stated need for Dr. Evans’s testimony
    14 In objecting on the basis of relevancy to Dr. Evans being allowed to
    testify that he had diagnosed Middlebrooks with schizophrenia in 2011 and
    2012, the prosecutor argued that, “if he’s not [qualified as] an expert [at trial,]
    he can’t testify as to a diagnosis [he made in the past], which is the only reason
    [the defense is] calling him. . . . If he’s not an expert[,] his testimony is
    meaningless.” Defense counsel responded that “[e]ven lay witnesses can testify
    just based upon their observations.” The trial court asked both sides, “do y’all
    have any case law that supports your position?” Defense counsel responded, “I
    never heard of such an objection so I do not have case law.”

    was to show that the same mental illness manifested many months
    before the crimes, with sufficiently severe symptoms to warrant
    extended involuntary hospitalizations, to counteract the State’s
    evidence that she was only feigning insanity after the homicide to
    avoid criminal liability for Sky’s death. The record shows that
    Middlebrooks was able to elicit such testimony from Dr. Evans, even
    without asking him to give opinion testimony about his diagnoses,
    and to connect her experts’ later diagnoses to Middlebrooks’s
    preexisting history of mental illness. 15 In addition, Dr. McKee, one
    of Middlebrooks’s expert witnesses, testified extensively about the
    15  At the hearing on Middlebrooks’s motion for a new trial, her trial
    counsel testified:
    It was important for me to show this insanity plea was not
    something that a lawyer made up at the last minute. I wanted to
    get into her history. I wanted to show why she was in the hospital,
    how long she was in the hospital, and what kind of treatment she
    had in the hospital, and what that treatment was generally for.
    That way I was able to satisfy the VA who did not want [Dr. Evans]
    to testify as an expert. But I got in all I wanted by showing that he
    has treated her and she had been diagnosed as psychotic[,] . . . and
    she was so dangerous that she had to stay in the hospital for . . . a
    number of weeks. . . . [Dr. Evans’s diagnosis] was not [a key to the
    defense]. . . . I just wanted to get that she was admitted in the
    hospital because she was schizophrenic, and I was able to get that
    in. And she was confined because she was schizophrenic, and I was
    able to get that in. And she was confined for a good period of time,
    and I was able to get that in without a diagnosis from Dr. Evans.

    records    he     reviewed     of    Middlebrooks’s       2011     and     2012
    hospitalizations, including her reported delusions and the diagnoses
    by VA physicians, including Dr. Evans. Given that defense counsel
    was able to elicit the desired evidence, Middlebrooks has not shown
    a reasonable probability that, but for defense counsel’s allegedly
    deficient performance with regard to accepting the limitations on
    Dr. Evans’s testimony, the outcome of the trial would have been
    different. Accordingly, this claim of error fails. See Hornbuckle v.
    State, 
    300 Ga. 750
    , 758 (6) (c) (
    797 SE2d 113
    ) (2017). 16
    Judgment affirmed. All the Justices concur.
    16  Under Georgia law, where alleged errors by the trial court and
    deficient performance by defense counsel involve evidentiary issues, courts
    consider collectively the prejudicial effect of those errors in considering
    whether a criminal defendant is entitled to a new trial. See State v. Lane, 
    308 Ga. 10
    , 14 (1) (
    838 SE2d 808
    ) (2020). For purposes of a cumulative-error
    analysis in this case, the assumed trial court evidentiary error is the admission
    of Dr. Vitacco’s testimony about some of the consequences of a verdict of not
    guilty by reason of insanity, which we have already determined to be harmless,
    and the assumed deficient performance of counsel is failing to object to the
    limitation of Dr. Evans’s testimony, which we have already determined did not
    prejudice Middlebrooks. We have considered the cumulative effect of this
    presumed evidentiary error and presumed deficient performance of counsel
    together and conclude that their collective effect is not sufficiently harmful to
    outweigh the strength of the properly admitted evidence of Middlebrooks’s
    guilt so as to warrant a new trial. See Perkins v. State, 
    313 Ga. 885
    , 904 n.22

    873 SE2d 185
    ) (2022).
