OPINION
MALONEY, Judge.
Appellant was convicted of capital murder committed in the course of burglary. Tex.Penal Code Ann. § 19.03(a)(2). The jury affirmatively answered the two special issues submitted to it and appellant was sentenced to death. Tex.Code Crim.Proc.Ann. art. 37.071 § 2(b), (e). Appeal to this Court is automatic. Tex.Code Crim.Proc.Ann. art. 37.071(h).
In his first point of error appellant claims the trial court erred in denying his motion for the appointment of an independent forensic pathologist to assist him in the preparation and presentation of his defense. We will reverse.1
I. Preservation of Error
The State contends that no error was preserved for review because appellant failed to obtain a ruling on his motion.
Appellant’s motion was presented at the end of the first day of testimony during the guilt phase of trial. After hearing arguments from the parties, the trial court stated that he would not rule on the issue until hearing the direct testimony of the State’s pathologist, Dr. Ralph Erdmann. The parties argued further about whether appellant could select his own expert. The trial court stated that it would permit the appointment of the expert selected by appellant if it ruled favorably on appellant’s motion, but reiterated that it was reserving the right to rule on the motion later.
The next day Erdmann testified on a bill of exceptions as to his qualifications as an expert.2 Immediately thereafter appellant asked the court whether it had made a determination on his motion for the appointment of a pathologist. The court responded that it had extensively researched the issue and would give a ruling after a short recess; however, no further proceedings appear in [336]*336the record for that day. The next day during Erdmann’s direct testimony before the jury, appellant objected to the State’s introduction of autopsy photographs. During his objection appellant stated “I would remind the Court that the Court previously denied my request for my own pathologist.” No one objected to this statement. Although some of appellant’s objections to the photos were unclear, he objected in part because he did not have his own pathologist to assist in cross-examining Erdmann regarding them.3 That objection was overruled.
The State does not contend that appellant’s objection and motion were not sufficient to apprise the court or the State of his complaint; rather, the State says error was not preserved because the trial court’s ruling on the motion does not appear in the record. While we require that a defendant’s objections be specific enough to effectively communicate his complaint to the court, we are less stringent in our requirements of the trial court’s ruling on an objection. A court’s ruling on a complaint or objection can be impliedly rather than expressly made. See, e.g., Chappell v. State, 850 S.W.2d 508, 510 (Tex.Crim.App.1993) (defendant’s objection to jury shuffle overruled when trial judge granted State’s motion to shuffle); Ramirez v. State, 815 S.W.2d 636, 650 (Tex.Crim.App. 1991) (trial judge “implicitly overruled” defendant’s objection to State’s question by directing witness to answer question); Beebe v. State, 811 S.W.2d 604, 605 (Tex.Crim.App. 1991) (where defendant requested additional time and trial court stated he would attempt to dispose of all pending cases if “humanly possible” in the morning, trial court’s response was sufficient to preserve error). A trial court’s ruling on a matter need not be expressly stated if its actions or other statements otherwise unquestionably indicate a ruling. Cf. Moody v. State, 827 S.W.2d 875 (Tex.Crim.App.1992), cert. denied, — U.S.— , 113 S.Ct. 119, 121 L.Ed.2d 75 (1993). In Moody, the defendant complained the trial court abused its discretion by its sua sponte exeusal of a veniremember. Although “the statement of facts [did] not include a transcription of the discussions between the trial court and this veniremember nor delineate the precise moment in time when the exeusal was made,” we concluded that comments by the trial court and testimony of the deputy clerk indicated the reasons for the exeusal and proved that it was made after the panel was sworn but before individual questioning. Id. at 879.
Appellant twice requested the court to make a ruling and then stated for the record that the court had denied his motion. Nei[337]*337ther the court nor the State corrected that statement. In addition, appellant renewed his motion in objecting to the introduction of Erdmann’s autopsy photographs, and the court expressly overruled that objection. We hold the record sufficiently reflects that the trial court ruled adversely to appellant’s motion and thus the issue was preserved for review.
II. The Merits of Appellant’s Motion
In Ake v. Oklahoma, 470 U.S. 68,105 S.Ct. 1087, 84 L.Ed.2d 53 (1985), the defendant requested the appointment of a psychiatrist to assist on the issue of his sanity at the time of the offense. The Supreme Court explained that due process requires access to the raw materials integral to the building of an effective defense. Id. at 77, 105 S.Ct. at 1093. While the State need not “purchase for an indigent defendant all the assistance that his wealthier counterparts might buy,” it must provide him the basic tools to present his defense within our adversarial system. Id, The Court set forth the following three factors as relevant considerations in determining “whether, and under what conditions, the participation of a psychiatrist is important enough to preparation of a defense to require the State to provide an indigent defendant with access to competent psychiatric assistance”:
The first is the private interest that will be affected by the action of the State. The second is the governmental interest that will be affected if the safeguard is to be provided. The third is the probable value of the additional or substitute procedural safeguards that are sought, and the risk of an erroneous deprivation of the affected interest if those safeguards are not provided.
Id.
The Supreme Court devoted only a paragraph to each of the first two factors. They stated that an individual’s interest in the accuracy of a proceeding where his life or liberty is at stake is “obvious and weighs heavily” in the analysis. Ake, 470 U.S. at 78, 105 S.Ct. at 1093. Given that the State also maintains an interest in the legitimacy of the verdict, the only interest the Supreme Court could identify that weighs against an accused’s interest in an accurate outcome is the State’s concern for judicial economy. In Ake, the Court concluded that the State’s interest in judicial economy was “not substantial, in light of the compelling interest of both the State and the individual in accurate dispositions.” Id. at 79, 105 S.Ct. at 1094.
The Court placed the greatest emphasis on the third factor, discussing the importance of psychiatric testimony in conveying to the factfinder an understanding of the defendant’s mental state and its potential impact on his behavior at the time in question. The Court concluded that the risk of an inaccurate verdict was high where the defendant was not assisted by a psychiatrist to “help determine whether the insanity defense is viable, to present testimony, and to assist in preparing the cross-examination of a State’s psychiatric witnesses.” Id. at 82, 105 S.Ct. at 1096. The Court further stated that where it is clear that the defendant’s sanity is likely to be a significant factor, “a defense may be devastated by the absence of a psychiatric examination and testimony; with such assistance, the defendant might have a reasonable chance of success.” Therefore, the Court held that
... when , a defendant demonstrates to the trial judge that his sanity at the time of the offense is to be a significant factor at trial, the State must, at a minimum, assure the defendant access to a competent psychiatrist who will conduct an appropriate examination and assist in evaluation, preparation, and presentation of the defense.
Id. at 83, 105 S.Ct. at 1096.
A. Ake Applies to Non-psychiatric Experts
Appellant contends that he was entitled under Ake to the assistance of his own pathologist. The State argues that the opinion of a pathologist is not comparable to the opinion of a psychiatrist so as to fall within the parameters of Ake. Appellant argues that the type of expert is immaterial and that the important question is whether the trial was fundamentally unfair without the assistance of the requested expert.
[338]*338Most courts that have considered the application of Ake have held that where an indigent defendant established a substantial need for an expert, without which the fundamental fairness of his trial will be called into question, Ake requires the appointment of an expert regardless of his field of expertise.4 As explained by the Eighth Circuit:
There is no principled way to distinguish between psychiatric and nonpsyehiatric experts. The question in each case must be not what field of expert knowledge is involved, but rather how important the scientific issue is in the case, and how much help a defense expert could have given.
Little v. Armontrout, 835 F.2d 1240, 1243 (8th Cir.1987), cert. denied, 487 U.S. 1210, 108 S.Ct. 2857, 101 L.Ed.2d 894 (1988). Ake is not limited to psychiatric experts; but the type of expert requested is relevant to the determination of whether the trial was fundamentally unfair without the expert’s assistance. The nature of an expert’s field and the importance and complexity of the issue will bear directly upon whether the appointment of an expert will be helpful. For instance, in reaching its conclusion in Ake the Supreme Court recognized that psychiatry is not an “exact” science, that experts within the field often disagree on important issues and that the issue of a defendant’s sanity was to jurors “complex and foreign.” Ake, 470 U.S. at 81, 105 S.Ct. at 1095.
The State argues that because a pathologist’s opinion is based upon “concrete observations” as compared to the opinion of a psychiatrist which is based upon more uncertain variables, Ake does not apply. Certainly human behavior involves variables that are more uncertain and elusive than the physical variables upon which a pathologist draws conclusions in conducting an autopsy. Nevertheless pathology, like psychiatry, is a sub-specialty of the science of medicine. Medicine in any of its sub-specialties eludes mathematic precision, as evidenced by the need for a “second opinion” with regard to any important medical question. Causation or mechanism of death are examples of important medical questions addressed by pathologists that require more than an objective or rote determination.5 We accordingly [339]*339reject the State’s contention that the appointment of a pathologist does not fall within the parameter of Ake. We hold only that the appointment of a pathologist is not per se excluded from the confines of Ake — in any given case, the necessity for the appointment under Ake will depend upon whether the defendant has made a sufficient threshold showing of need for the expertise of a pathologist in that particular case.
B. Appellant’s and the State’s Interests
As discussed above, the accused’s and the State’s interests must be factored into the analysis in each case, in addition to the defendant’s threshold showing which is the weightiest consideration. In this case, we view the positions of the respective parties much as the interests of the parties in Ake. Appellant, charged with capital murder, has an interest in the accuracy of the proceedings that “is obvious and weighs heavily” in the analysis. Ake, supra. The State likewise maintains an interest in the accuracy of the result. Appellant seeks a pathologist to assist in his defense. Pathologists are readily available in all metropolitan areas and most communities of any size, although there might not have been a pathologist readily available in Randall County where appellant’s trial took place. At any rate, the trial court in this case had already approved the use of a particular pathologist from Dallas were he to rule favorably on appellant’s motion. We cannot conclude that the cost of bringing such expert to Randall County, within a day’s drive of Dallas, would be unmanageable. Appellant’s counsel testified that the expert charged $250 an hour, that the expert projected this to be a “one-day case” and that she expected her total fee would be approximately “$2,000 plus expenses.” Given the weight of appellant’s interest in an accurate result, we conclude that the State’s interest in judicial economy is “not substantial” in this case. Accordingly, like in Ake, appellant’s interest weighs more heavily than the State’s.
C. Appellant’s Threshold Showing
Addressing the third consideration in the analysis, Ake held that a defendant must make a preliminary showing that his sanity was “likely to be a significant factor” at trial. Ake, 470 U.S. at 74, 82-88, 86, 105 S.Ct. at 1091-92, 1095-96, 1097-98. In Caldwell v. Mississippi, 472 U.S. 320, 323-24 n. 1, 105 S.Ct. 2633, 2637 n. 1, 86 L.Ed.2d 231 (1985), the Supreme Court declined to entertain a petitioner’s Ake claim where he “offered little more than undeveloped assertions that the requested assistance would be beneficial.” A brief discussion of the facts is helpful for purposes of determining whether appellant made a sufficient threshold showing.
Sometime after midnight on May 12, 1990, appellant and five of his companions decided to burglarize a house. According to appellant’s confessions, they intended to burglarize a house that was unoccupied, but “hit the wrong house.” After kicking in the door to the deceased’s trailer house appellant and his cohorts saw the deceased in his bedroom with a flashlight. A struggle ensued and the offenders beat and kicked the deceased. They took a few items and fled the scene, leaving the deceased lying on the floor. Ap[340]*340pellant stated in his written confession that the deceased was alive when they left the scene, but “wasn’t breathing right, kind of fanny but I thought he would be alright.”
The deceased’s autopsy was conducted by Dr. Erdmann who concluded that the mechanism of death was “acute cerebral edema with subsequent severely increased intra-cra-nial pressure, compression of the vital medul-lary centers, and ending in cardio-respiratory arrest.” The autopsy further concluded that the deceased “had had previous open heart surgery but it did not result in complications that might have aggravated or be in a way directly or indirectly responsible for the final factual outcome of this case.” One of appellant’s codefendants had retained Dr. Leroy Riddick, the Director of the State Medical Examiner’s Office of Alabama, who reviewed Erdmann’s findings and reported that he had serious questions about Erdmann’s conclusions. Appellant’s motion was based largely upon Riddick’s affidavit.
Appellant claimed that the mechanism of death6 would be a “significant factor” at trial so as to entitle him to the assistance of a pathologist. In his written motion and in his oral presentation before the trial court appellant argued that he needed his own forensic pathologist to evaluate, pursue, and present a defense based upon the theory that the deceased died from a heart attack, not from blows to the head. Appellant explained that the blows incurred by the deceased were not consistent with an intentional killing or with deliberateness, reasoning that since such blows would not usually cause the death of an adult male, death was not a result that was foreseeable. Evidence that the deceased did not die as a result of the blows, but rather due to a heart attack would support appellant’s defense that he did not intend to kill the deceased by beating him and that he did not act deliberately with the reasonable expectation that death would result.7
In support of his motion, appellant presented an affidavit from Riddick which stated that he “strongly disagre[ed]” with Erd-mann’s conclusion that the deceased had died solely from the blunt force injuries, as those injuries were “much too superficial to cause the death of a healthy man of [the deceased’s] age.” He further stated that “[i]n all likelihood, [the deceased] would have survived those injuries, but for the fact that he had a badly diseased heart.” Riddick stated that he was “quite disturbed” by Erdmann’s failure to investigate the deceased’s heart condition as an alternative cause of death and noted that there was nothing contained in the autopsy to support Erdmann’s conclusion that it was not a contributing cause. Riddick was also troubled by the fact that Erdmann did not take notes during the autopsy and had erased the audio tape of his observations. He found this particularly disturbing in view of the fact that neither the autopsy report nor the photographs documented “any find-[341]*341mg about the condition of [the deceased’s] heart, skull or brain that would enable a competent pathologist to rule out heart disease as a contributing cause of death.”
On cross-examination of Erdmann in his bill of exception appellant offered evidence that Erdmann’s conclusions in an autopsy in another case were found to be invalid when the body was exhumed and a second autopsy performed by another pathologist.
Appellant’s defensive theory was to establish reasonable doubt on the issue of intent and/or deliberateness by showing that appellant could not have foreseen that his actions would result in the death of the deceased. Riddick’s affidavit supported appellant’s theory and seriously questioned Erdmann’s conclusions, specifically about the mechanism of death. Other facts pointed to by appellant were also consistent with his theory — evidence that neither appellant nor his companions were armed, appellant’s statement in his confession that they “hit the wrong house” and intended to burglarize an unoccupied house, and his statements that the deceased was still alive when they left the scene and he believed the deceased would be alright. Appellant also raised a question through his cross-examination of Erdmann that there was reason to doubt the reliability of Erd-mann’s work.
In cases holding that a sufficient showing was not made under Ake, the defendant typically has failed to support his motion with affidavits or other evidence in support of his defensive theory, an explanation as to what his defensive theory was and why expert assistance would be helpful in establishing that theory, or a showing that there was a reason to question the State’s expert and proof. See, e.g., Ake, 470 U.S. at 85-86, 105 S.Ct. at 1097-98 (petitioner’s defense of insanity was announced and trial court was aware of facts supporting that defense — petitioner’s behavior before the court was “so bizarre” that competency hearing was ordered, state psychiatrist found petitioner incompetent and recommended that he be committed, petitioner’s competence was maintained only by sedation); Yohey, 985 F.2d at 227 (defendant’s motion for ballistics expert was supported only by affidavit from counsel speculating on firing of weapons and presented no evidence suggesting that findings in autopsy reports were inaccurate or subject to disagreement between experts); Moore, 809 F.2d at 717-18 (defendant’s request not sufficient where he did not advise court of type of expert sought or role expert would play, he did not offer name of expert that might be available or state what the expert could have contributed to defense); Edwards, 868 S.W.2d at 698 (defendant failed to make sufficient showing for DNA expert where motion not supported with affidavit or other proof showing particular need, did not disclose defense theory or discuss issue of mis-identification); State v. Evans, 710 S.W.2d 530, 534 (Tenn.Crim.App.1985) (defendant’s request for ballistics expert distinguished from Ake where record contained nothing to indicate unreliability of State’s ballistics tests and defendant’s contention based entirely on speculation as to what another expert might have found). In cases holding that the defendant was entitled to the appointment of an expert, the defendant has generally made his defensive theory clear to the trial court and supported it with factual allegations and/or evidence that expert testimony would support his theory. See, e.g., Coker, 412 N.W.2d at 593 (defendant’s request for expert sufficient where defendant informed trial court of intent to rely on intoxication as defense and supported request with facts demonstrating defendant’s substance abuse problems and associated seizures); Dubose v. State, No. CR-89-359, slip op. at 32, — So.2d —, —, 1993 WL 381482 (1993) (defendant entitled to DNA expert where he specifically alleged what type of expert he needed, how the expert would be useful in challenging the State’s case and why the challenged evidence was critical).
In the instant case appellant explained his defensive theory to the trial court and how it could effect the outcome in his case. Appellant supported his motion with the affidavit of an expert, Dr. Riddick, who seriously questioned the findings in the autopsy report as to the mechanism of death and raised questions about the thoroughness and quality of Erdmann’s performance in relation thereto. In addition, the expert set forth his own opinion as to the mechanism of death which [342]*342was consistent with appellant’s defensive theory. Appellant also pointed to facts surrounding the offense that were consistent with his theory. We hold that appellant clearly established that the mechanism of death was to be a significant factor at trial.8 By overruling appellant’s motion for the appointment of a pathologist appellant was denied a “basic tool” essential to developing and presenting his defensive theory.
The State argues that appellant did not make a threshold showing under Ake because his needs were satisfied by the testimony of Dr. Sparks Veasey and because appellant’s defense consisted of impeaching the State’s evidence unlike the affirmative defense of insanity where the defendant bears the burden of proof.
The State asserts that Veasey’s testimony was “exactly the same type of testimony and evidence [appellant] hoped to present from the appointment of an independent pathologist”. We note initially that the substance of Veasey’s testimony does not impact appellant’s threshold showing since the trial court did not know at the time of its ruling on appellant’s motion exactly what Veasey would testify to or even whether he would testify.9 Moreover, the appointment of an expert under Ake is not only for that expert’s testimony.10 In De Freece v. Texas, 848 S.W.2d 150 (Tex.Crim.App.1993), cert. denied, — U.S. —, 114 S.Ct. 284, 126 [343]*343L.Ed.2d 234 (1993), the State argued that the trial court’s appointment of a “neutral” psychiatrist was sufficient to satisfy due process under Ake. We rejected the State’s contention, concluding that “neutral” experts are insufficient to satisfy due process in our adversarial system:
[T]he adversarial model rests on the assumption that each party to a dispute, motivated by self-interest, will develop his position to the greatest extent possible ... thus providing the factfinder an optimal vantage from which to gauge all relevant facts and make an informed decision on the merits.
⅜ ⅜ ⅜ ⅜ ⅜ ⅜
In an adversarial system due process requires at least a reasonably level playing field at trial. In the present context that means more than just an examination by a “neutral” psychiatrist. It also means the appointment of a psychiatrist to provide technical assistance to the accused, to help evaluate the strength of his defense, to offer his own expert diagnosis at trial if it is favorable to that defense, and to identify the weaknesses in the State’s case, if any, by testifying himself and/or preparing counsel to cross-examine opposing experts.
De Freece, 848 S.W.2d at 158-59. Accordingly, once he established that cause of death was likely to be a significant factor at trial, appellant was entitled to more than an expert to testify on his behalf — he was also entitled to “technical assistance ... to help evaluate the strength of [that] defense, ... and to identify the weaknesses in the State’s case, if any, by ... preparing counsel to cross-examine opposing experts.” Id. Appellant did not have access to an expert in that capacity.11
The State also argues that because insanity is an affirmative defense on which the defendant bears the burden of proof, Ake is distinguishable from appellant’s case where appellant bore no such burden. We reject that distinction. In Ake the Supreme Court emphasized that one of the petitioner’s needs for a psychiatrist was to assist in every aspect of his defensive theory including impeachment of the State’s psychiatric witnesses. Ake, 470 U.S. at 82, 105 S.Ct. at 1095-96. The Court further stated that the petitioner was entitled to the assistance of a psychiatric expert to rebut the State’s assertion that he presented a continuing threat to society, yet the petitioner bore no burden of proof as to the special issue. These portions of the Court’s opinion in Ake recognize that a defensive strategy of exposing weaknesses in the State’s proof and presenting the jury with alternative theories is a legitimate and necessary function of our adversarial system.
[344]*344III. Harmless Error
While the State does not specifically argue that a harmless error analysis should be conducted, some of its discussion concerning Veasey’s testimony suggests that conclusion. Accordingly, we take this opportunity to decide whether a harm analysis need be conducted upon a determination of Ake error. We turn to guidance from the United States Supreme Court in this regard.
The case most often cited for the formulation of the federal harmless error rule is Chapman v. California, 386 U.S. 18, 87 S.Ct. 824, 17 L.Ed.2d 705 (1967). There, the California Supreme Court addressed whether “there can ever be harmless constitutional error.” Id. at 21, 87 S.Ct. at 826. Noting that state harmless error rules are creatures of state law and appropriately apply to errors of state procedure and state law, the Supreme Court assumed responsibility for fashioning the appropriate rule to apply to errors against the United States Constitution.
Recognizing that there may be some constitutional errors that are “unimportant and insignificant” in light of the entire trial, the Court rejected the defendants’ contention that all constitutional errors should be deemed harmful, requiring automatic reversal. Id. at 22, 87 S.Ct. at 827. Based upon the standard announced in Fahy v. Conn., 375 U.S. 85, 84 S.Ct. 229, 11 L.Ed.2d 171 (1963), “whether there is a reasonable probability that the evidence complained of might have contributed to the conviction,” and the common law rule which placed on the beneficiary of the error the burden of proving that no injury was suffered as a result the error, the Court held:
... before a federal constitutional error can be held harmless, the court must be able to declare a belief that it was harmless beyond a reasonable doubt.
Chapman, 386 U.S. at 24, 87 S.Ct. at 828. Despite its holding that constitutional errors are not harmful per se, the Court nevertheless recognized its previous indications that certain constitutional rights are so basic to a fair trial that their violation can never be treated as harmless. Id. at 23 & n. 8, 87 S.Ct. at 827-28 & n. 8 (citing Payne v. Arkansas, 356 U.S. 560, 78 S.Ct. 844, 2 L.Ed.2d. 975 (1958) (coerced confession); Gideon v. Wainwright, 372 U.S. 335, 83 S.Ct. 792, 9 L.Ed.2d 799 (1963) (right to counsel); Tumey v. Ohio, 273 U.S. 510, 47 S.Ct. 437, 71 L.Ed. 749 (1927) (impartial judge).
The question of when a constitutional error is immune from the Chapman harmless error analysis was addressed in Arizona v. Fulminante, 499 U.S. 279, 111 S.Ct. 1246, 113 L.Ed.2d 302 (1991). Fulmi-nante dealt with whether the admission of an involuntary confession was subject to a harm analysis:
The admission of an involuntary confession — a classic “trial error” — is markedly different from the other two constitutional violations referred to in the Chapman footnote as not being subject to harmless-error analysis. One of those violations, involved in Gideon v. Wainwright, 372 U.S. 335, 83 S.Ct. 792, 9 L.Ed.2d 799, 93 A.L.R.2d 733 (1963), was the total deprivation of the right to counsel at trial. The other violation, involved in Tumey v. Ohio, 273 U.S. 510, 47 S.Ct. 437, 71 L.Ed. 749, 50 A.L.R. 1243 (1927), was a judge who was not impartial. These are structural defects in the constitution of the trial mechanism, which defy analysis by “harmless-error” standards. The entire conduct of the trial from beginning to end is obviously affected by the absence of counsel for a criminal defendant, just as it is by the presence on the bench of a judge who is not impartial. Since our decision in Chapman, other cases have added to the category of constitutional errors which are not subject to harmless error the following: unlawful exclusion of members of the defendant’s race from a grand jury, Vasquez v. Hillery, 474 U.S. 254, 106 S.Ct. 617, 88 L.Ed.2d 598 (1986); the right to self-representation at trial, McKaskle v. Wiggins, 465 U.S. 168, 177-178, n. 8, 104 S.Ct. 944 [950-951, n. 8] 79 L.Ed.2d 122 (1984); and the right to public trial, Waller v. Georgia, 467 U.S. 39, 49, n. 9, 104 S.Ct. 2210 [2217, n. 9] 81 L.Ed.2d 31 (1984). Each of these constitutional deprivations is a similar structural defect affecting the framework within which the trial proceeds, rather than simply an error in the trial process itself. [345]*345“Without these basic protections, a criminal trial cannot reliably serve its function as a vehicle for determination of guilt or innocence, and no criminal punishment may be regarded as fundamentally fair.” Rose v. Clark, 478 U.S. [570], at 577-578, 106 S.Ct. 3101 [3106], 92 L.Ed.2d 460 (1986) (citation omitted).
It is evident from a comparison of the constitutional violations which we have held subject to harmless error, and those which we have held not, that involuntary statements or confessions belong in the former category. The admission of an involuntary confession is a “trial error,” similar in both degree and kind to the erroneous admission of other types of evidence. The evidentiary impact of an involuntary confession, and its effect upon the composition of the record, is indistinguishable from that of a confession obtained in violation of the Sixth Amendment — of evidence seized in violation of the Fourth Amendment — or of a prosecutor’s improper comment on a defendant’s silence at trial in violation of the Fifth Amendment. When reviewing the erroneous admission of an involuntary confession, the appellate court, as it does with the admission of other forms of improperly admitted evidence, simply reviews the remainder of the evidence against the defendant to determine whether the admission of the confession was harmless beyond a reasonable doubt.
Fulminante, 499 U.S. at 309-10, 111 S.Ct. at 1264-65. Thus, if the constitutional violation is such that it impacts the structural underpinnings of the entire trial, it defies subjugation to a harm analysis and calls for automatic reversal. However, if the constitutional violation is akin to “trial error” that is in the nature of the erroneous admission of evidence, the harmless error rule of Chapman applies.12
This analysis leads us to ask whether the error in the instant case was structural error or trial error. We conclude the error is structural. We would first point out, as we have previously noted, that the Supreme Court in Ake reversed and remanded for a new trial without conducting a harm analysis. See De Freece, 848 S.W.2d at 160. It is clear from a reading of Ake that the error at issue is structural in nature. The Court’s analysis in Ake began with a revisiting of the “elementary principle” that every criminal defendant, indigent or otherwise, must have “a fair opportunity to present his defense.” Ake, 470 U.S. at 76, 105 S.Ct. at 1092. The Court spoke in terms of the “basic tools of an adequate defense” and the “raw materials integral to the building of an effective defense” in concluding that in certain defined circumstances, discussed at length earlier in this opinion, a defense expert is such an element. The Court emphasized that the accuracy of the jury’s determination, a substantial interest common to both parties, is “dramatically enhanced” with the appointment of an expert in the circumstances outlined therein. Id. at 83, 105 S.Ct. at 1096. We can conceive of few errors that are more structural in nature than one which eliminates a basic tool of an adequate defense and in doing so dramatically affects the accuracy of the jury’s determination. We held previously in this opinion that “[b]y overruling appellant’s motion for the appointment of a pathologist appellant was denied a “basic tool’ essential to developing and presenting his defensive theory.” The structural underpinnings of appellant’s trial, from beginning to end, were affected by his inability to present an effective defense.13 Accordingly, we hold [346]*346that the denial of the appointment of an expert, consistent with Ake, amounts to structural error which cannot be evaluated for harm.
Having held that appellant made a sufficient threshold showing that he was entitled to the assistance of a pathologist to assist in the evaluation, preparation and presentation of his defense, we reverse the judgment of the trial court and remand for a new trial. See Ake, supra.
McCORMICK, P.J., and WHITE and KELLER, JJ., dissent.
