IN THE COURT OF CRIMINAL APPEALS
OF TEXAS




No. PD-0670-07


CLARK DEWAYNE MAYS, Appellant

v.

THE STATE OF TEXAS




On Discretionary Review of Case 06-06-00075-CR
of the Sixth Court of Appeals,
Lamar County


Womack, J., delivered the opinion of the Court, in which Keller, P.J., and
Price, Keasler, Hervey, and Cochran, JJ., joined. Holcomb, J., filed a
dissenting opinion, in which Meyers and Johnson, JJ., joined.


	The appellant, during voir dire in a murder trial, sought to raise the subject of diminished
capacity as it affects a defendant's culpable mental state at the time of the offense. The trial court
ruled that it would exclude any evidence of the appellant's diminished capacity and invited the
appellant to proffer evidence. The State here raises the issue of whether the appellant's proffer of
evidence was sufficient to preserve that ruling for appeal. Holding that it was not sufficient, we
shall reverse the judgment of the Court of Appeals.
Trial Proceedings
	The appellant was charged with capital murder; (1) the State chose not to seek the death
penalty. The case proceeded to trial before a jury. During voir dire, the appellant made the
following statement: "The law in Texas is that we can look at [defendants'] history, their medical
history, their psychological history, their psychiatric history, and we can look at those factors to
determine their state of mind." The prosecution responded, "Your Honor, may we approach?"
The judge excused the jury from the courtroom. There followed a discussion wherein the trial
judge considered the admissibility of mental-impairment evidence.
	At the outset of the discussion, the trial court ruled:
After reading the Jackson case, it appears to me that there is no defense of
diminished capacity. There is no need for this type of evidence of diminished
capacity for the purposes of sentencing because there is no issue of sentencing,
there is only an issue of guilt or innocence, so I've ruled that I will not hear any
evidence of diminished capacity. [Defense Counsel] asked for an opportunity to
make a record and I'm glad to give him that opportunity. You may proceed.	Defense counsel proceeded to argue that, although Jackson v. State (2) rejected diminished
capacity as an affirmative defense in Texas, it recognized the relevance and admissibility of
evidence of mental impairment to "show that the defendant lacked the capacity, if you will, to
form the specific intent or the intent element of murder." He then stated: "[T]he evidence in this
case, were we allowed to present it, would show that because of mental and medical impairment,
the defendant lacked, at the time of the alleged commission of this crime, the ability to form the
requisites of the mental state required of intentional and knowing." He also outlined the
applicable Texas law that he believed rendered the evidence admissible.
	Defense counsel reviewed with the court each of a series of slides he had prepared to
show and discuss with the jury panel during voir dire. For instance, Defendant's Exhibit 1
(mistakenly marked in the record as State's Exhibit 1) said: 
CONDITION OF THE MIND: You are instructed that you may consider all
relevant facts and circumstances surrounding the killing, if any, and the previous
relationship existing between the accused and the deceased, if any, together with
all relevant facts and circumstances going to show the condition of the mind
of the accused at the time of the offense, if any.Defense counsel summarized his planned discussion with the jury panel, with regard to this slide,
as follows:
[W]e would have voir dired the jury as it relates to the condition of the mind of
the accused at the time of the offense. We would have asked questions concerning
Article 38.36 as it relates to relevant facts and circumstances going to show the
condition of the mind. (3)The subjects of the remaining slides and counsel's summary of them were similarly confined to
Texas law regarding mental states and lesser-included offenses, as well as general statements
regarding the questions counsel anticipated asking the panel. Counsel offered the slides as
exhibits, and the court admitted them for the record.
	Defense counsel further objected to the ruling against using the evidence for voir dire.
The trial judge affirmed his ruling and reiterated his understanding that Jackson allowed
diminished-capacity evidence only at punishment, not at the guilt phase. Because punishment
was not at issue in this case, he said that the evidence would not be admissible. He also excluded
the evidence because of prejudice, irrelevance, and confusion to the jury. Defense counsel argued
these points and finally stated:
	Judge, my position is that the blanket exclusion of evidence of mental
impairment in the guilt/innocence phase of this trial to show that as a matter of
evidence the defendant lacked the ability or capacity, if you will, to form either an
intentional or knowing states [sic] of mind as culpable mental states for the
offense of murder is not the correct statement of the law.
	At this point in time, if we can take that issue up on appeal, without having
considered waiving the appeal on the point, we would be of the opinion that if you
consented to that, we would enter a plea of guilty to the offense of capital murder
in this case. I'm saying that with the reservation that because I have been told that
no evidence whatsoever under any circumstances would be admissible as it
applies to that issue, that I might not and would not put on any record as to the
defendant's past mental health history other than I would offer into evidence -
well, I just - at this point that's my position.
	Now, if we are not willing to go on the record from the court's perspective
and say that it just depends on what evidence I heard from whatever mental health
expert that you presented, I need to go ahead and bring my mental health expert
down and make my record. But if the court's of the opinion, as I understand it as a
blanket ruling, that no matter what that evidence said, then I think we have to get
into the probative prejudicial point of it because I don't want to waive an appellate
point in regards to that aspect of it. But if the court's position is that regardless of
the prejudicial element of it, that Texas law does not allow the introduction of
evidence of mental impairment in the guilt-innocence phase to show the defendant
lacked the capacity to form the necessary mens rea of intentionally or knowingly,
I'm willing to proceed forward with the court's permission to appeal that
particular point.
	The trial judge agreed to certify the appeal (4) and accept the appellant's guilty plea.
	The State asked to make an offer of proof from its expert witness, to counter the
defendant's expert.
	[PROSECUTOR]: I thought that [Defense Counsel] said that he was going to do
an offer of proof with an expert.

	[DEFENSE COUNSEL]: No, he indicated that he would not - as I heard you,
judge, not fall back on the probative prejudice argument, and it was a blanket
ruling that such evidence was inadmissible. That's how I understood you to say it.

	[TRIAL COURT]: That's the way I meant it.

	[PROSECUTOR]: In that case, we don't need to do that.

	[TRIAL COURT]: It's not necessary to put on any evidence of mental capacity.
It's all presumed in the defendant's favor in an appeal of this type.

	The appellant pleaded guilty, and his sentence was set automatically at life
imprisonment. (5) He appealed.
Court of Appeals Decision
	The issue on direct appeal centered on whether the evidence would have been admissible
at the guilt phase of the trial and, therefore, whether the trial court erred in excluding it. (6) As the
trial court had done, the Court of Appeals analyzed the question under Jackson. The Court said
that, although Jackson made plain that Texas jurisprudence does not include an affirmative
defense of diminished capacity, it "does, however, recognize something very closely akin to it, 
this being 'simply a failure-of-proof defense in which the defendant claims that the State failed to
prove that the defendant had the required state of mind at the time of the offense.'" (7)
	The Court of Appeals found the appellant's proffer to have fallen within the ambit of the
Jackson diminished-capacity doctrine. (8) The Court recognized that "there was no showing of the
nature of the evidence which was to be produced." (9) But it looked to the appellant's stated goal
for offering the evidence, which "was to show that he would have explored relevant facts and
circumstances going to show the condition of his mind at the time of the killing and to apply it to
the lesser included offense of negligent homicide." (10) The Court determined this to be a
permissible purpose-and therefore the evidence to be admissible at the guilt phase of the
trial-under Jackson, and it concluded that the trial court had abused its discretion in excluding
the evidence. (11)
	The Court ascribed to the trial court's ruling not only the fact that "no evidence was
presented from which [it could] determine whether the trial court's erroneous ruling substantially
affected Mays'[s] substantial rights," but also the appellant's guilty plea itself. (12) Because it
determined the erroneous ruling to have necessarily contributed to the conviction, the Court
reversed the judgment and remanded the case to the trial court. (13) The State petitioned for review.
Our Review
	In this court, the State's first ground is whether the appellant failed to preserve error for
review. Before we reach the State's ground on its merits, we address the appellant's contention
that the preservation issue is not properly before this court.
	The appellant argues that the State raises the issue here only for the first time and that the
Court of Appeals did not render a decision, either explicit or implicit, on procedural default.
Because this court's jurisdiction is limited to reviewing "decisions" of the courts of appeals, he
says, we have no jurisdiction to review the issue in this case. We disagree.
	This court has said, "Preservation of error is a systemic requirement that a first-level
appellate court should ordinarily review on its own motion." (14) Precisely for this reason, in Haley
we found a procedural-default question, raised by the State for the first time in its petition for
discretionary review, to be properly before this court, and in so deciding, reached the merits of
the issue. (15) Moreover, here there is no reason to believe that the Court of Appeals deviated from
ordinary procedure. Although neither party raised the issue in the Court of Appeals, it was
incumbent upon the Court itself to take up error preservation as a threshold issue. Implicit in the
Court's review on the merits was a decision on procedural default, which is therefore properly
before this court. Accordingly, we now turn to the question of whether the appellant preserved
error.
	In order to preserve error regarding a trial court's decision to exclude evidence, the
complaining party must comply with Rule of Evidence 103 by making an "offer of proof" which
sets forth the substance of the proffered evidence. (16) Rule 103(a)(2) provides: "Error may not be
predicated upon a ruling which  excludes evidence unless a substantial right of the party is
affected, and  the substance of the evidence was made known to the court by offer, or was
apparent from the context within which questions were asked." The offer of proof may consist of
a concise statement by counsel, or it may be in question-and-answer form. (17) If in the form of a
statement, the proffer "must include a reasonably specific summary of the evidence offered and
must state the relevance of the evidence unless the relevance is apparent, so that the court can
determine whether the evidence is relevant and admissible." (18)
	"The primary purpose of an offer of proof is to enable an appellate court to determine
whether the exclusion was erroneous and harmful. A secondary purpose is to permit the trial
judge to reconsider his ruling in light of the actual evidence." (19)
	This court's opinion in Warner is instructive, as it was predicated on a similar set of
circumstances. Warner, in a hearing before voir dire on the State's motion in limine, objected to
a portion of the motion requesting that the defendant not discuss in front of the jury any evidence
concerning his counseling or rehabilitation for a stress disorder. (20) The defendant told the trial
court he intended to adduce evidence at the guilt phase that he was a Vietnam War veteran who
suffered from post-traumatic stress disorder (PTSD), and that he had received counseling for the
disorder. (21) He further contended that the evidence was admissible to prove that he lacked the
specific intent to commit the charged offenses. (22) Warner "did not, however, define 'post-traumatic stress disorder' for the court or explain how he intended to prove that he suffered from
the disorder. [He] also did not explain how evidence of PTSD would be relevant to the question
of specific intent." (23) The trial court granted the State's motion and found the evidence to be
admissible only at the punishment phase of the trial. (24) Warner did not offer the evidence of PTSD
at the guilt phase and was found guilty by a jury. (25)
	On direct appeal, Warner argued that the trial court erred in excluding the evidence from
the guilt phase. The Third Court of Appeals affirmed. This court initially granted Warner's
petition for discretionary review on the same question, but after determining from the record that
he had not preserved the error for review, we dismissed his petition as improvidently granted. We
concluded that he had not made an adequate offer of proof, either during the hearing on the
motion or at the guilt phase. (26)
	There can be no doubt that the trial judge in the instant case intended his ruling excluding
all evidence of the appellant's diminished capacity to apply, not simply for purposes of voir dire,
but to the entire guilt phase of the trial. In order to preserve error, the appellant therefore was
obliged to make an offer of proof that extended beyond the anticipated questions to, and topics of
discussion with, potential jurors during voir dire. He was required to proffer, with some degree of
specificity, the substantive evidence he intended to present, during the guilt phase, of the
appellant's mental impairments and their impact on his mental state at the time of the offense.
This he failed to do.
	The appellant's proffer of his slides and the questions he would have posed to the jury in
voir dire provide us with just that-the substance of his anticipated dialogue with the jury panel.
The record reveals that the appellant proffered nothing that rises to the level contemplated in our
Rules of Evidence and this court's precedent. The only statement on the record that might even
be considered to approach an adequate offer of proof was his statement that, "[T]he evidence in
this case, were we allowed to present it, would show that because of mental and medical
impairment, the defendant lacked, at the time of the alleged commission of this crime, the ability
to form the requisites of the mental state required of intentional and knowing." But as is evident
from Warner, this sort of summary, in the most general and cursory terms, without any of the
meat of the actual evidence, will not suffice to preserve error. The appellant's counsel himself
admitted, during the course of the discussion, "I would say that how could we know if that
evidence would be more prejudicial than probative when we haven't even had a chance to see
what that evidence is."
	This is not a case in which the trial judge afforded the appellant no opportunity to make a
proffer. On the contrary, the appellant's counsel had every occasion to make a proper offer of
proof. We can see from the excerpts of the record above, however, that both the trial judge and
the appellant's counsel were mistaken as to the need for the substance of the proffer which the
law requires. The record reflects that trial counsel was prepared to "bring [his] mental health
expert down and make [his] record" of the appellant's "past mental health history" had the ruling
been more limited in scope. But the appellant's counsel clearly believed that the trial judge's
"blanket ruling" excluding evidence of mental impairment from the guilt phase shielded him
from the necessity of proffering evidence of the appellant's mental impairment. This is simply
incorrect. That the trial judge sanctioned this mistaken belief by agreeing that such a proffer was
unnecessary, does not relieve the appellant from his burden. It was the responsibility of the
appellant to ensure that the substance of the evidence was placed into the record, and he failed to
do so.
	Because the appellant failed to make a proper offer of proof, we hold that he did not
preserve his complaint for appeal. We reverse the judgment of the Court of Appeals and affirm
the judgment of the trial court. (27)
