¶1 “Cross-examination that attempts to impeach by slipping in unrelied on opinions and conclusions without calling the experts to testify is improper.” Robert H. Aronson & Maureen A. Howard, The Law of Evidence in Washington § 8.03 [8] [b] at 8-67 (5th ed. 2016). Such questioning does not fall within the ambit of ER 703, which addresses “facts or data . . .
upon which an expert
bases an opinion or inference.” (Emphasis added.) Nor does it fall within the scope of ER 705, which, as to the facts or data on which an expert bases an opinion, allows that the expert may “be required to disclose the underlying facts or data on cross examination.” Indeed, if the purpose of the impeachment attempt is to show that the testifying expert
should
have relied on the “unrelied on opinions” of others, then the “unrelied on opinions” are being offered for their truth and are thus inadmissible hearsay. ER 801(c). On the other hand, if the proponent of the “unrelied on opinions” impeachment attempt is offering the evidence without regard for its truth, then the evidence lacks relevance—because no expert is required to base an opinion on falsehoods. Irrelevant evidence is likewise inadmissible. ER 401, 402.
¶2 In this case, Jimi Hamilton’s sole expert witness, Dr. Stuart Grassian, was repeatedly impeached on cross-examination with the observations, opinions, and conclusions— contained in Hamilton’s voluminous medical records—of various nontestifying medical professionals. This was allowed notwithstanding that Dr. Grassian did not claim to have relied on these observations, opinions, or conclusions in forming his own opinions. And this was allowed notwithstanding that the medical records themselves were never admitted into evidence. This misapplication of the rules of evidence unquestionably prejudiced Hamilton, whose defense depended solely on Dr. Grassian’s testimony. The improper latitude granted to the State in cross-examining Dr. Grassian calls into question the fairness of the trial. Accordingly, we reverse.

¶3 Jimi Hamilton was charged with one count of assault in the second degree of a corrections officer (Officer Trout). The assaultive act occurred at the Monroe Correctional Complex, where Hamilton was serving a sentence.
¶4 At trial, Hamilton testified in his own defense. His defense to the charge was diminished capacity resulting from a mental disease or defect. Hamilton’s sole testifying expert witness was a psychiatrist, Dr. Stuart Grassian.
¶5 Dr. Grassian’s testimony focused on two topics. First, he testified to the general state of mental health services provided to prisoners and to the effect on prisoners of lengthy or repeated periods of solitary confinement.
Second, in support of Hamilton’s diminished capacity defense, he testified to his opinion that Hamilton suffered from relevant mental illnesses at the time that he committed the assaultive act that gave rise to the charge at issue. The
claim of error herein arises from the prosecutor’s attempted impeachment of the latter testimony.
Dr. Grassian’s Opinion Testimony
¶6 On direct examination, Hamilton’s counsel established that Dr. Grassian formulated his opinion of Hamilton’s mental state at the time of the assaultive act by conducting interviews with Hamilton and several of his family members. Dr. Grassian also testified that he reviewed numerous documents, including (1) Hamilton’s statement to the police following the assaultive act, (2) the information and affidavit of probable cause filed herein, (3) statements from various witnesses to the incident, (4) the victim’s medical records, and (5) Hamilton’s medical records. Hamilton’s medical records consisted of approximately 2,380 pages.
¶7 Dr. Grassian testified, on direct examination, to the overall state of Hamilton’s medical records and the quality of the evaluations contained therein. He described the records as “helter-skelter,” changing all the time, and often incoherent. He acknowledged that there were opinions in the medical records that were well founded. He also observed, however, that in other parts of the medical records there was no continuing record or accumulation of knowledge, and that many medical professionals who opined therein had nothing to base their information on, forming their observations, opinions, and conclusions regarding Hamilton based on their impressions of the moment. Dr. Grassian also generally criticized evaluations within the
medical records for diagnosing Hamilton, without further explanation, as suffering from antisocial personality disorder, borderline personality disorder, or as having a tendency to fake a mental illness.
¶8 Thereafter, Dr. Grassian testified to his opinion regarding Hamilton’s mental health generally and Hamilton’s mental state at the time of the assaultive act. Dr. Grassian opined that Hamilton suffers from bipolar mood disorder, a mental defect presenting volatile emotional changes and episodic periods of psychosis.
¶9 Dr. Grassian further opined that, due to this disorder, Hamilton was not able to form the requisite mental state to commit the charged offense. Specifically, Dr. Grassian testified that Hamilton was in a dissociative state—an altered state of consciousness—at the time of the assaultive act. Based on his opinion that Hamilton was in a dissociative state, Dr. Grassian concluded that Hamilton lacked the capacity to form the intent to commit an injurious act against Officer Trout.
¶10 The State, during its cross-examination of Dr. Grassian, inquired as to whether Dr. Grassian had relied on Hamilton’s medical records in formulating his opinion. Dr. Grassian responded that he did not rely on the records, stating that the medical records were relevant to his decision-making, but that he did not necessarily make a decision based on the records.
¶11 Shortly thereafter, the prosecutor asked Dr. Gras-sian whether he made a list of the documents on which he had relied when formulating his expert opinion. Dr. Grassian responded that he had previously made a list of the entries in the medical records on which he had relied but had been unable to locate it prior to trial. Dr. Grassian further indicated that, due to the large volume of Hamilton’s medical records, he was unable to reconstruct the list before he was due to testify and thus could not identify with particularity those entries in Hamilton’s records on which he had relied in formulating his opinions.
The Prosecutor’s Impeachment of Dr. Grassian’s Testimony
¶12 During Dr. Grassian’s cross-examination, the State attempted to impeach his testimony regarding Hamilton’s bipolar mood disorder and Hamilton’s mental state at the time in question with the observations, opinions, and conclusions of medical professionals set forth in Hamilton’s medical records. The prosecutor’s mode of impeachment proceeded as follows: (1) directing Dr. Grassian to a page in Hamilton’s medical records containing a different medical professional’s observations, opinions, or conclusions that contradicted Dr. Grassian’s opinions, (2) identifying or asking Dr. Grassian to identify that medical professional and his or her professional or educational expertise, (3) reading the excerpt from the entry aloud or asking Dr. Grassian to read therefrom, and (4) demanding that Dr. Grassian substantively respond to the statements therein.
¶13 None of the identified medical professionals testified at Hamilton’s trial. None of the pages or entries from Hamilton’s medical records referenced during Dr. Gras-sian’s cross-examination were admitted as exhibits at trial.
¶14 One of the first medical professionals referenced by the prosecutor in attempting to impeach Dr. Grassian’s testimony was a psychiatrist, identified only as Dr. Kar-nik,
who recorded evaluations of Hamilton in 1999. Notwithstanding that (1) Dr. Karnik did not testify at trial, (2) the medical records generated by Dr. Karnik were not admitted as exhibits, and (3) Dr. Grassian never indicated that he had relied on Dr. Karnik’s opinions, observations, or conclusions in forming his own opinions, the trial court permitted the State to impeach Dr. Grassian with the entries generated by Dr. Karnik.
¶15 In particular, the prosecutor read from two entries generated by Dr. Karnik, memorializing Dr. Karnik’s belief that Hamilton, in 1999, faked having a mental illness, engaged in polysubstance abuse, presented with a lack of remorse for his wrongful conduct, and failed to assume responsibility for his actions. The prosecutor demanded that Dr. Grassian substantively respond to Dr. Karnik’s conclusions and challenged Dr. Grassian as to whether he was more qualified than Dr. Karnik was to evaluate Hamilton’s mental health.
¶16 During the second day of Dr. Grassian’s cross-examination, the State requested that Dr. Grassian read from a chart note generated by another nontestifying medical professional, identified as Dr. Rolf Kolden. Notwithstanding that (1) Dr. Kolden did not testify at trial, (2) the medical record generated by Dr. Kolden was not admitted as an exhibit, and (3) Dr. Grassian never indicated that he had relied on Dr. Kolden’s chart note in forming his opinions, the trial court permitted the prosecutor to attempt to impeach Dr. Grassian’s testimony with information recorded by Dr. Kolden.
¶17 The purpose of introducing Dr. Kolden’s chart note was to impeach Dr. Grassian’s testimony with Dr. Kolden’s observation that Hamilton was—at the time he saw Dr. Kolden—faking a mental illness in order to improve his situation. The State further questioned Dr. Grassian as to whether Dr. Kolden was a person qualified to make the observations described in the chart note.
¶18 The prosecutor additionally referenced a medical record, generated in 2001, by another nontestifying witness, identified phonetically as Dr. Cardell. Even though (1) Dr. Cardell did not testify at trial, (2) the medical record referenced was never admitted as an exhibit, and (3) Dr. Grassian never indicated that he had relied on Dr. Cardell’s recorded entry in forming his own opinions, the trial court permitted the State to impeach Dr. Grassian’s testimony with information contained in that entry. The purpose of
referencing the entry generated by Dr. Cardell was to attempt to impeach Dr. Grassian’s testimony with Dr. Cardell’s diagnosis that Hamilton—in 2001—did not present symptoms of psychosis but was instead faking a mental illness. The State further queried Dr. Grassian as to whether Dr. Cardell was a person qualified to make such a diagnosis.
¶19 The prosecutor later directed Dr. Grassian to a page in Hamilton’s medical records containing a diagnosis made by a fourth nontestifying witness, identified phonetically as Dr. Joseph Dooby. The diagnosis was from 1995. Although (1) Dr. Dooby did not testify at trial, (2) the medical record generated by Dr. Dooby was never admitted as an exhibit, and (3) Dr. Grassian never indicated that he had relied on Dr. Dooby’s observations, conclusions, or opinions in forming his own opinions, the trial court permitted the State to attempt to impeach Dr. Grassian’s testimony with information contained in the entry generated by Dr. Dooby.
¶20 The purpose of introducing Dr. Dooby’s chart note was to impeach Dr. Grassian’s testimony by contrasting it with Dr. Dooby’s diagnosis that Hamilton suffered from antisocial personality disorder, not bipolar mood disorder. The State further questioned Dr. Grassian as to whether Dr. Dooby, who had treated Hamilton when he was still a juvenile, was more qualified to diagnose Hamilton than was Dr. Grassian.
¶21 In addition, throughout the cross-examination, the prosecutor referenced the observations, opinions, and conclusions of various other medical professionals, as set forth in Hamilton’s medical records, in an attempt to impeach Dr. Grassian’s testimony. This included reading information contained in the medical records in front of the jury. These various other professionals were not identified by name either by the prosecutor or Dr. Grassian. As above, these professionals did not testify at trial, the referenced records were never admitted as exhibits, and Dr. Grassian never indicated that had relied on those record entries in forming his own opinions.
Defense Counsel’s Objections, the Prosecutor’s Response, and the Trial Court’s Rulings
¶22 Throughout Dr. Grassian’s cross-examination, defense counsel repeatedly objected to the State’s mode of impeachment. Defense counsel first interjected after the prosecutor began attempting to impeach Dr. Grassian’s diagnosis with information contained in Hamilton’s medical records. Defense counsel asserted that the statements were hearsay, indicating that she was “objecting to the line of questioning on both a 705 objection, that it’s not a basis for his opinion, and hearsay objection.” The prosecutor replied that the information in Hamilton’s medical records was exempt from the hearsay rules and that the records were being properly used for impeachment.
¶23 The trial court stated that “if this is something he relied on in his diagnosis, I will allow the questions” and that the prosecutor “can ask the questions, but I’m not quite sure where it is at this point that it’s still impeachment.”
¶24 The State continued its cross-examination and continued to recite statements attributed to various medical professionals and contained in Hamilton’s medical records. In response, defense counsel began objecting to the prosecutor’s method of questioning on the ground that the prosecutor was “testifying” and failing to direct a question to Dr. Grassian. The trial court sustained several of these objections.
¶25 Shortly thereafter, the prosecutor again recited from Hamilton’s medical records, quoting from another non-testifying medical professional who had attributed a quotation to Hamilton. Defense counsel objected, claiming that the statement constituted double hearsay: “I just want to point out what she’s referring to is a doctor quoting a [medical professional] quoting Mr. Hamilton. So it’s . . . double hearsay. It’s not admissible, Your Honor.” Apparently flummoxed by the trial court’s previous rulings,
defense counsel now requested that the trial court issue a limiting instruction indicating that the observations, opinions, and conclusions contained in the medical records could not be considered for their truth. The prosecutor responded that the information set forth in Hamilton’s medical records could be considered for its truth because the information included statements made for the purpose of medical diagnosis or treatment and included statements made by Hamilton that were now being offered against him.
¶26 The trial court allowed the prosecutor to continue to impeach Dr. Grassian’s testimony in this manner, but issued a limiting instruction to the jury, informing the jurors that the observations, opinions, and conclusions in the medical records could not be considered for the truth of the matters asserted therein and could only be considered for the purpose of evaluating the credibility of Dr. Gras-sian’s diagnosis.
¶27 The prosecutor then continued the cross-examination and continued framing questions to Dr. Grassian by reading from the medical records. As Dr. Grassian’s cross-examination dragged on, defense counsel interposed six separate objections on the basis that the prosecutor herself was “testifying” by reading extensively from the medical records without directing to Dr. Grassian a question to which he could respond. The trial court sustained each objection.
¶28 Immediately after Hamilton’s sixth such objection, the trial judge excused the jury. Thereafter, Hamilton’s counsel noted a continuing objection to the State’s line of questioning:
I continue to have concerns about the style in which [the prosecutor] is asking questions. I am not going to keep object
ing, because I look like I’m a jerk when I keep interjecting. I know the Court is taking some action in asking her to ask questions, but I’m noting a continuing objection, and I don’t want to have to make that objection continuously in front of the jury.
¶29 Also during this exchange, Hamilton himself asserted that the prosecutor was presenting evidence in violation of the hearsay rules. Specifically, Hamilton argued to the trial court that, because the prosecutor was quoting out-of-court statements by a medical professional who, in turn, was quoting Hamilton, the prosecutor was presenting evidence that constituted double hearsay. Hamilton further argued to the trial court that the medical professional’s statements were hearsay and that the State “can’t use Rule 705 as a bootstrap to relate inadmissible facts and data to this jury.”
¶30 The prosecutor replied that, with regard to Dr. Grassian’s testimony, she was “entitled to impeach that with the facts that he reviewed, that he considered, or should have considered when making his statements and his opinions.” Notwithstanding that the prosecutor was wrong as to all three of these assertions, the trial court appeared to acquiesce in this view of the law and took no further remedial action in response to the objections raised by Hamilton and his counsel.
¶31 Later, because Dr. Grassian’s testimony elicited only excerpts from Dr. Grassian’s report without its full context, Hamilton’s counsel offered the report in its entirety for admission pursuant to ER 106, which permits a party to introduce any other part of a writing introduced by another party, “which ought in fairness to be considered contemporaneously with it.” The trial court denied this request.
¶32 The jury found Hamilton guilty as charged. The conviction constituted Hamilton’s third strike pursuant to Washington’s Persistent Offender Accountability Act, RCW
9.94A.570. Accordingly, the trial court sentenced him to a lifetime term of confinement without the possibility of parole.
¶33 Hamilton now appeals.
II
¶34 To properly analyze the primary issue presented, it is necessary to comprehend that the prosecutor never established that Dr. Grassian actually relied on the various entries in the medical records that the prosecutor repeatedly referenced in her cross-examination. Neither were the medical records themselves admitted into evidence as an exhibit. And none of the medical professionals whose observations, opinions, or conclusions—as entered into the medical records—were referenced in front of the jury actually testified at trial.
¶35 The State defended its mode of impeachment by claiming that it was entitled to impeach Dr. Grassian’s testimony “with the facts that he reviewed, that he considered, or should have considered when making his statements and his opinions.” The State was wrong on all counts.
¶36 The method of impeachment engaged in by the prosecutor was at variance with the law in four major respects. First, while it is true that when medical records have been admitted into evidence a testifying medical professional may be questioned about the content of those records, the medical records at issue herein were never admitted into evidence. Second, while it is true that an expert witness may be questioned about the information or data on which the expert relied in forming his or her expert opinions, here the State never established that Dr. Gras-sian relied on any of the various entries about which it questioned him. Third, given that Dr. Grassian did not testify that he had relied on those entries, if the State was attempting to convince the jury that Dr. Grassian
should have
given importance to those entries, then the State was
necessarily
offering the entries for the truth of that which was asserted therein. Thus, it was improper hearsay testimony. Finally, if the State was—as now claimed—not offering the evidence for the truth of that which was asserted therein, then the entries were not relevant—because no expert witness can be impeached based on the expert’s refusal to base an opinion on a falsehood. Only by treating the entries as true can they be relevant. And if they are to be treated as true, they are hearsay. Because Dr. Grassian never claimed to rely on the various entries, ER 703 and ER 705 do not excuse them from the hearsay bar.
¶37 Hamilton’s counsel initially objected to the State’s tactic, claiming that the prosecutor was proffering inadmissible hearsay. However, after it became apparent that the trial court had acquiesced to or adopted the prosecutor’s rationale for allowing this manner of impeachment, Hamilton’s counsel resorted to objecting that the prosecutor was herself testifying, rather than asking questions.
As a consequence, the trial court improperly permitted Dr. Grassian’s testimony to be repeatedly impeached with the observations, opinions, and conclusions contained in Hamilton’s medical records throughout the two trial sessions during which Dr. Grassian’s cross-examination took place.
¶38 By allowing the State to bring forth this improper evidence to impeach Hamilton’s sole expert witness, the trial court failed in its duty as gatekeeper. Over the course of Dr. Grassian’s cross-examination, these errors amassed into a systemic prejudice against Hamilton’s case and, ultimately, deprived him of a fair trial.
A
¶39 Hamilton asserts that the trial court erroneously applied ER 703 and ER 705 so as to permit the State to impeach Dr. Grassian’s testimony with the observations, opinions, and conclusions of medical professionals set forth within Hamilton’s medical records. This is so, Hamilton contends, because the State never established that Dr. Grassian relied on these various record entries in formulating his expert opinions and, thus, these “unrelied on opinions” are hearsay and, accordingly, inadmissible. We agree.
¶40 ER 801(c) defines “hearsay” as “a statement, other than one made by the declarant while testifying at the trial or hearing, offered in evidence to prove the truth of the matter asserted.” ER 802 sets forth the circumstances in which hearsay is inadmissible: “Hearsay is not admissible except as provided by these rules, by other court rules, or by statute.”
¶41 In combination, ER 703 and ER 705 function as exceptions to the hearsay rule that permit disclosure on cross-examination of the facts or data on which an expert witness relies in forming his or her opinion. ER 703 discusses the allowable bases for an expert witness’s opinion:
The facts or data in the particular case
upon which an expert bases an opinion
or inference may be those perceived by or made known to the expert at or before the hearing. If of a type reasonably relied upon by experts in the particular field in forming opinions or inferences upon the subject, the facts or data need not be admissible in evidence.
(Emphasis added.) ER 705 sets forth the circumstances in which an expert witness on cross-examination may be required to disclose the facts or data underlying his or her opinion:
The expert may testify in terms of opinion or inference and give reasons therefor without prior disclosure of the underlying facts or data, unless the judge requires otherwise. The expert may in any event be required to disclose the underlying facts or data on cross examination.
¶42 Hence, when an expert witness bases an opinion on facts or data, the expert may be required to disclose and discuss these facts or data on cross-examination, even if the underlying facts or data would otherwise be inadmissible as hearsay. The key, of course, is that the expert witness must have based an opinion on the facts or data, as set forth in ER 703, in order to be questioned thereon, as allowed by ER 705.
¶43 However, if the facts or data on which the testifying expert relied are found in a hearsay report—that is, a report containing an opinion of a nontestifying expert—“the evidence of the report is not admitted as substantive proof of the report’s truth; rather, the report is admitted for the limited purpose of showing the basis of the expert’s opinion.” Edward J. Imwinkelried, Evidentiary Foundations § 9.03[4][c] at 402 (9th ed. 2015).
¶44 Our Supreme Court, in
Washington Irrigation & Development Co. v. Sherman,
106 Wn.2d 685, 686-87, 724 P.2d 997 (1986), considered the propriety of impeaching an expert witness’s testimony with the contents of a non-testifying professional’s report that the witness had seen
but had not relied on in formulating his opinion. The court held that such impeachment was improper.
Wash. Irrig.,
106 Wn.2d at 688.
¶45 Adopting the view of the Fifth Circuit, our Supreme Court instructed that the party seeking to impeach an expert witness pursuant to ER 703 and ER 705 has the burden of demonstrating that the expert, in formulating his or her opinion, relied on the facts or data proffered by the impeaching party. “ ‘Until defendant established that plaintiff had relied on the report of the other doctor, it was improper for the defendant to read from that report in cross-examining plaintiff’s witness.’ ”
Wash.
Irrig., 106 Wn.2d at 689 (quoting
Bobb v. Modern Prods., Inc.,
648 F.2d 1051, 1056 (5th Cir. 1981)).
¶46 Because the party seeking to impeach established only that the expert witness had previously seen the proffered report, the court concluded that the party’s burden to establish that the expert had actually relied on the report was not met. Having seen or read a report, the court held, did not equate to having relied on the report. “The respondents in this case failed to establish that Sherman’s expert relied upon the reports of the non-testifying doctors, although Dr. Bridgeford did admit that he had seen them.”
Wash. Irrig.,
106 Wn.2d at 689. Accordingly, the court held that “unrelied upon opinions and conclusions should not be introduced in cross examination.”
Wash. Irrig.,
106 Wn.2d at 689-90.
¶47 This holding is both controlling and in accordance with the weight of authority. “Cross-examination that attempts to impeach by slipping in unrelied on opinions and conclusions without calling the experts to testify is improper.” Aronson & Howard,

¶48 Herein, Dr. Grassian opined that, due to Hamilton’s bipolar mood disorder, Hamilton did not have the capacity to form the requisite mental state to commit the crime of assault. Dr. Grassian testified that he formulated his opinion from conducting interviews with Hamilton and his family members. Dr. Grassian also indicated that he had reviewed Hamilton’s medical records, along with other records, in preparation for testifying.
¶49 During Dr. Grassian’s cross-examination, the State attempted to impeach his testimony, identifying four medical professionals by name, explaining their expertise, and reading into the record their opinions that categorized Hamilton as having a tendency to fake mental illnesses, as psychopathic, and as not demonstrating remorse or assuming responsibility for his actions. However, during the attempted impeachment, the prosecutor did not establish that Dr. Grassian relied on any of these nontestifying professionals’ opinions, observations, or conclusions in formulating his own opinions.
¶50 During Dr. Grassian’s cross-examination, the State inquired as to whether Dr. Grassian had created a list of those matters on which he had relied in formulating his opinions. Dr. Grassian testified that he had created such a list, but that he had been unable to locate it in preparing for court and that he was further unable to reconstruct the list prior to being called to testify. Although the prosecutor did ask Dr. Grassian if he had read or reviewed various portions of Hamilton’s medical records, the State did not
further inquire as to which records Dr. Grassian had relied on as a basis for his diagnosis or conclusions.
¶51 The State’s mode of impeachment was not authorized by ER 703 and ER 705. The State never established that Dr. Grassian relied on the opinions of the four nontestifying medical professionals with whose opinions he was confronted or, for that matter, any other entry in Hamilton’s voluminous medical records. Although Dr. Grassian indicated that he reviewed the medical records, this general statement did not establish that Dr. Grassian
relied
on the specifically identified medical professionals’ observations, opinions, or conclusions in formulating his opinions. Consequently, the State improperly impeached Dr. Grassian’s testimony with hearsay evidence. Had the State wished to impeach Dr. Grassian “or introduce additional medical testimony by using the reports of nontestifying physicians, they should have done so by calling these physicians as witnesses. By doing this, the use of hearsay could have been avoided and the nontestifying physicians could have been cross-examined.”
Wash. Irrig.,
106 Wn.2d at 689.
¶52 Accordingly, the trial court erred by permitting the prosecutor to impeach Dr. Grassian with “unrelied on opinions” that constituted inadmissible hearsay.
B
¶53 At trial, the State also defended its references to entries in Hamilton’s medical records by claiming that the entries fell within three other exceptions to the hearsay rule: statements made by a party opponent, statements made for the purpose of medical diagnosis or treatment, and statements contained in a business record. The State was wrong.
¶54 The State referenced and quoted statements attributed to Hamilton and set forth in his medical records. The entries that memorialized these utterances were made by people who did not testify at trial. Offered for their truth, unless the State established that an exception to the hearsay rule applied both to the statements attributed to Hamilton
and
to the written entries made by the people quoting Hamilton, the proffered evidence constituted double hearsay. Although the statements attributed to Hamilton may have constituted the admissions of a party-opponent, ER 801(d)(2), the State failed to establish an exception applicable to the other layer of hearsay—the assertions made by the people who generated the entries into the medical records claiming that Hamilton actually uttered the words attributed to him. As the State concedes in its appellate briefing:
The defendant’s statements were an admission of a party opponent, and therefore not hearsay. ER 801(d)(2). However!,] those statements were reported by non-testifying witnesses. The recording party’s statement was hearsay. ER 801(a). It is not likely there was an exception to that second level of hearsay for at least some of those records. For that reason!,] admission of those statements for substantive purpose was error. ER 805.
Br. of Resp’t/Cross Appellant at 76-77.
¶55 We agree.
¶56 At trial, the prosecutor additionally claimed that she could properly introduce statements attributed to Hamilton in his medical records because these statements were made for the purpose of medical diagnosis or treatment.
See
ER 803(a)(4). However, just as the State’s contention regarding admissions of a party opponent, upon examination, melts away like butter in the sun, so does this assertion. Here, too, an exception to the second layer of hearsay is not identified. The records themselves were never admitted as an exhibit. At trial, no medical professional testified that Hamilton actually made the statements attributed to him. Thus, the statements “were reported by non-testifying witnesses.”
And, as with the prior issue, “[t]he recording party’s statement was hearsay.”
See
Br. of Resp’t/Cross Appellant at 76-77. For this reason, it was improper for such statements to be referenced in front of the jury.
¶57 The State also asserted at trial that Hamilton’s medical records constituted business records pursuant to the Uniform Business Records as Evidence Act (UBRA), RCW 5.45.020, and entries therein thus were not hearsay. Although “the UBRA is a statutory exception to hearsay rules,” the act “does not create an exception for the foundational requirements of identification and authentication.”
State v. DeVries,
149 Wn.2d 842, 847, 72 P.3d 748 (2003) (citing 5C Karl B. Tegland, Washington Practice: Evidence Law and Practice § 803.42, at 23 (4th ed. 1999)). The trial prosecutor never called the witnesses necessary to identify and authenticate the various medical records. More to the point, the prosecutor never offered the records for admission. And, of course, they were never admitted. Thus, the assertion that the UBRA somehow inoculates the statements in the medical records from the effect of a hearsay objection falls flat. The claim fails.
¶58 Nevertheless, on appeal, the State asserts that Hamilton is barred from objecting to the State’s reliance on the business records exception to the hearsay rules because Hamilton failed to object to the State’s rationale at trial. The State is wrong.
¶59 The State never sought to admit the records. Thus, Hamilton was presented with no opportunity to object to their admission. He thus waived no claim of error.

¶60 The remaining justification presented by the prosecutor at trial was that, even if evidence of the “unrelied on opinions” was not offered for its truth, the State was nevertheless still entitled to impeach Dr. Grassian’s testimony on the ground that Dr. Grassian
should have relied
on such opinions. Again, this is wrong.
¶61 In essence, this claim attempts to divorce a court’s evaluation of the admissibility of the “unrelied on opinions” from the rules of hearsay or, alternatively, from the rules of relevancy.
¶62 As discussed above, hearsay, in pertinent part, is an out-of-court statement offered in evidence for its truth. ER 801(c). Clearly, by asserting that Dr. Grassian should have relied on the “unrelied on opinions,” the State is attempting to impeach Dr. Grassian’s testimony. Ostensibly, the “un-relied on opinions” possess the potential to impeach due to their truthful qualities, thus discrediting Dr. Grassian, who elected to not rely on them in formulating his own opinion. Otherwise, such “unrelied on opinions” would not serve to impeach Dr. Grassian’s testimony, as an expert who refuses to rely on falsehoods remains unimpeached. Thus, proffered in this way, the “unrelied on opinions” evidence constitutes hearsay and is inadmissible. ER 801(c).
¶63 Alternatively, by asserting that Dr. Grassian should have relied on the “unrelied on opinions” regardless of their truth, the State fails to establish how that evidence of the “unrelied on opinions” is relevant. If the sole purpose behind the proffer is to impeach Dr. Grassian’s testimony for failing to rely on the “unrelied on opinions” but the opinions are not introduced for their truth, then the evidence fails “to make the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence.” ER 401. No expert should rely on falsehoods. Thus, proffered in this manner, the “unrelied on opinions” are irrelevant and inadmissible. ER 402.

¶64 Hamilton asserts that the State’s improper impeachment of his sole expert witness prejudiced him, warranting a new trial. He is correct.
¶65 “[E]videntiary error will not be reversed absent a showing that the error prejudiced the defendant.”
Aubin v.
Barton,
123 Wn. App. 592, 608, 98 P.3d 126 (2004) (citing
Kramer v. J.I. Case Mfg.
Co., 62 Wn. App. 544, 562, 815 P.2d 798 (1991)).
¶66 The central issue in this case was Hamilton’s mental state at the time of the assaultive act. Dr. Grassian was Hamilton’s only expert witness. He testified as to Hamilton’s mental capacity and as to whether Hamilton could form the requisite intent to commit the charged offense. Had the jury credited Dr. Grassian’s testimony, it had a duty to acquit Hamilton.
¶67 The prosecutor’s mode of impeachment seriously undermined Hamilton’s ability to assert his diminished capacity defense.
See, e.g., Brandt,
425 A.2d at 165 (“The use of the [hearsay] report in this manner had considerable prejudicial impact upon appellants’ case, for [the testifying expert witness] was the appellants’ sole expert witness on the critical factual question.”). We are left with the firm conviction that Hamilton did not receive a fair trial.
¶68 The judgment is reversed and the cause is remanded for a new trial.
¶69 The remainder of this opinion has no precedential value. Therefore, it will be filed for public record in accordance with the rules governing unpublished opinions.
