Lead Opinion
An expert in forensic science testified as to her opinion that a substance was cocaine, based upon her independent analysis of testing performed by another analyst in her laboratory. The Court of Appeals held that this testimony violated defendant’s Sixth Amendment right to confront witnesses against him. We disagree and reverse.
On the night of 16 May 2007, Officer Craig Vollman of the Charlotte Mecklenburg Police Department (CMPD) was on patrol duty in the University City area. Around 10:30 p.m. a car driven by defendant pulled into an Exxon gas station. Officer Vollman observed that the car’s thirty-day temporary tag was “ratty and old” and the “dates looked to be tampered with.” When defendant parked in front of the gas station store, Officer Vollman pulled his patrol car behind defendant’s vehicle and approached him to speak about the thirty-day tag. While defendant looked through the glove compartment for the car’s registration paperwork, Officer Vollman shined his flashlight around the car to check for weapons. Upon shining the light in the storage compartment of the open driver’s door, he saw what he believed to be cocaine packaged in a plastic bag.
Officer Vollman asked defendant what was in the bag. According to Officer Vollman’s testimony, defendant stated, “It’s mine,” and responded affirmatively that it was cocaine but that “it was for personal use.” Officer Vollman placed defendant under arrest. He then found “eight separate plastic sandwich baggies” in the same door compartment as the cocaine. He also searched defendant and found $304 in cash in his pocket. After defendant had been transported to the Mecklenburg County jail, another officer weighed the confiscated
At trial the State sought to introduce Tracey Ray of the CMPD crime lab as an expert in forensic chemistry. During voir dire proceedings on the matter, defendant sought to exclude admission of a lab report created by a non-testifying analyst and any testimony by any lab analyst who did not perform the tests or write the lab report. Defendant based this motion primarily on Sixth Amendment grounds, arguing that admission of this evidence would violate his right to confront witnesses against him. The trial court ruled that Ray could testify about the practices and procedures of the CMPD crime lab, her review of the testing in this case, and her independent opinion concerning the testing. But the trial court excluded admission of the non-testifying analyst’s lab report under Rule of Evidence 403.
Before the jury, the State introduced Ray as an expert in forensic chemistry. Ray testified she had been a forensic chemist for approximately eleven years and had analyzed substances more than one thousand times for trial purposes. Ray explained the standard procedures for receipt and storage of substances sent to the CMPD crime lab. She testified that, based on the initials and control number on the plastic bag containing the white substance — which had been admitted into evidence as Item Number 9 — the substance had been sent to the CMPD crime lab. She stated the initials “JPM” on the item indicated to her that a chemist named Jennifer Mills, who formerly had worked at the crime lab, “was in receipt of this evidence and that she sealed this particular piece of evidence.”
Ray then explained, based on her knowledge of the lab’s standard procedures, what would happen to an item such as Item Number 9 when it arrived for testing: First, the analyst would ensure that the control numbers on the property report and the actual property matched. Then, the analyst would weigh the substance and perform what is called a “presumptive test” to give an indication of what the substance might be. For substances suspected to be cocaine, the presumptive test is a cobalt thiocyanate test. If the substance turns blue, this indicates that cocaine may be present. Next, the analyst would perform a “confirmatory test” to determine the identity of the substance, using a gas chromatograph mass spectrometer (GCMS) or an infrared spectrometer (FTIR). The instruments that perform these tests record the results and data within the machine, allowing for
Ray also explained that the lab has standard procedures for ensuring that the testing instruments are in working order. CMPD lab procedure dictates that all instruments be tested weekly and monthly, with the results recorded in each instrument’s maintenance log. Ray testified that she had reviewed the maintenance logs and determined that all the instruments appeared to have been in working order when Item Number 9 was tested.
Ray testified that she conducted a “peer review” on the chemical analysis of Item Number 9 for defendant’s trial. She reviewed all the lab notes and data from the testing instrument. She stated that the color test and the GCMS test performed on the substance are tests that “experts in the field of forensic chemistry would rely upon ... in performing [sic] the opinion as to the identity of a chemical substance.” The prosecutor asked Ray whether, based on her training and experience and her review of the case file here, she had formed an independent expert opinion about the substance at issue in this case. Defense counsel objected and was overruled. Ray testified, “My conclusion was that the substance was cocaine.”
On cross-examination defense counsel further clarified that “any opinions [Ray] g[a]ve in court about the nature of this substance [were] based entirely on testing done by someone else” and that Ray was not present when the tests were performed. Defense counsel also further clarified that Ray’s testimony assumed the testing analyst, Mills, had followed standard lab procedures in her testing of Item Number 9.
The jury convicted defendant of possession of cocaine. The Court of Appeals reversed the trial court, relying on State v. Williams,
“Conclusions of law are reviewed de novo and are subject to full review.” State v. Biber,
To resolve the issue raised in this case, we must examine the North Carolina Rules of Evidence in light of recent Confrontation Clause jurisprudence. The North Carolina Rules of Evidence allow for expert testimony “in the form of an opinion, or otherwise,” if the expert’s “scientific, technical or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue,” provided: “(1) The testimony is based upon sufficient facts or data[;] (2) The testimony is the product of reliable principles and methods [and] (3) The witness has applied the principles and methods reliably to the facts of the case.” N.C. R. Evid. 702(a). The expert may base the opinion on facts or data “made known to him at or before the hearing.” Id. R. 703. “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.” Id.
While the North Carolina Rules of Evidence permit an expert to present an opinion based on substantively inadmissible information, this evidentiary rule must comport with constitutional requirements. The Sixth Amendment to the United States Constitution provides that “[i]n all criminal prosecutions the accused shall enjoy the right... to be confronted with the witnesses against him.” U.S. Const, amend. VI. The jurisprudence interpreting this clause has undergone significant changes in recent years.
Since 2004 the Court has considered the application of Crawford in several cases involving forensic reports. In Melendez-Diaz v. Massachusetts,
In 2011 the Court considered “whether the Confrontation Clause permits the prosecution to introduce a forensic laboratory report containing a testimonial certification — made for the purpose of prov
In her concurring opinion in Bullcoming, Justice Sotomayor highlighted some of the scenarios not presented in that case: (1) The State presents an alternate purpose for the report; (2) The in-court witness “is a supervisor, reviewer, or someone else with a personal, albeit limited, connection to the scientific test at issue”; (3) “[A]n expert witness was asked for his independent opinion about underlying testimonial reports that were not themselves admitted into evidence”; and (4) The State “introduced only machine-generated results, such as a printout from a gas chromatograph.” Id. at_,
Most recently, the Supreme Court considered Crawford’s application in Williams v. Illinois,_U.S._,_,
The four-Justice plurality concluded that (1) as the basis of the expert’s opinion, the statement was not admitted for the truth of the matter asserted, and (2) the Cellmark report “plainly was not prepared for the primary purpose of accusing a targeted individual.” Id. at_,_,
Despite the lack of definitive guidance on the issue before us, a close examination of Williams v. Illinois seems to indicate that a qualified expert may provide an independent opinion based on otherwise inadmissible out-of-court statements in certain contexts. Both the plurality and dissent agreed that an expert’s opinion may ultimately be admissible, but they disagreed as to the foundational information required. See id. at _, _,
We believe our prior holding on this issue is consistent with this conclusion. In 2001 we stated that when an expert gives an opinion, “[i]t is the expert opinion itself, not its underlying factual basis, that constitutes substantive evidence.” State v. Fair,
A related issue is whether an expert who bases an opinion on otherwise inadmissible facts and data may, consistent with the Confrontation Clause, disclose those facts and data to the factfinder. Machine-generated raw data, typically produced in testing of illegal drugs, present a unique subgroup of this type of information. Justice Sotomayor has noted there is a difference between a lab report certifying a defendant’s blood-alcohol level and “machine-generated results, such as a printout from a gas chromatograph.” Bullcoming, _U.S. at_,
We turn now to the instant case. Before reaching the dispositive legal issue, we must address matters of procedure. Defendant alleges that several portions of Ray’s testimony were erroneously admitted, yet defendant objected only once during the course of Ray’s testimony. “In order to preserve an issue for appellate review, a party must have presented to the trial court a timely request, objection, or motion, stating the specific grounds for the ruling the party desired the court to make if the specific grounds were not apparent from the contéxt.” N.C. R. App. P 10(a)(1). While unpreserved evidentiary error in criminal cases may be reviewed for plain error, “the defendant must ‘specifically and distinctly’ contend that the alleged error constitutes plain error.” State v. Lawrence,
Before the jury Ray was certified as an expert in forensic chemistry and testified regarding the CMPD crime lab’s standard procedures and her review of the tests associated with the substance at issue. The prosecutor then asked:
Q. Based on your training and experience in the field of forensic chemistry and your employment at the CMPD crime lab as well as other labs prior to that and your review of the file in this case, did you have a chance to form your own independent expert opinion as to the identity of the substance in control number 16826?
A. Yes, I did.
Q. What is your independent expert opinion?
[DEFENSE COUNSEL]: Objection, your Honor. I don’t need to be heard further.
THE COURT: Yes, ma’am. Objection overruled, you may answer.
A. My conclusion was that the substance was cocaine.
Q. Is that still your opinion currently?
A. Yes, it is.
Based on defendant’s arguments at the earlier voir dire hearing, it is clear that this objection was based on the Confrontation Clause.
Q. And are these tests [color test, melting point, and GCMS] standards such that other experts in the field of forensic chemistry would rely upon them in performing [sic] the opinion as to the identity of a chemical substance?
A. Yes, they are.
Further, the prosecutor established that Ray’s opinion was her own, independently reasoned opinion — not “surrogate testimony” parroting the testing analyst’s opinion. See Bullcoming,_U.S. at__.,
Q. And for trial today were you asked to review the chemical analysis that was performed on Item Number 9, control number 16826?
A. Yes, I did.
Q. And did you do that review?
A. Yes.
Q. And what complaint number is associated with that, this case and that control number?
A. The complaint number is 20070516223000.
Q. And what control number is that?
A. 200716826.
Q. When you conducted this peer review, specifically what documents did you review?
A. I reviewed the drug chemistry worksheet or the lab notes that the analyst wrote her notes on and the data that came from the*13 instrument that was in the case file and then I also reviewed the data that was still on the instrument and made sure that was all there too.
As part of her review, Ray analyzed the “reviewable data” generated by the GCMS machine. Ray testified that the machine internally records the data and there is no way to make alterations to what is recorded. As she stated on cross-examination, the GCMS machine produces a graph based on its testing, from which Ray was able to determine “the molecular weight of the substance and how it breaks down and relate that back to the chemical structure.” Ray compared the machine-produced graph to the data from the lab’s sample library and concluded that the substance was cocaine.
This expert opinion, from Ray’s own analysis of the data, constituted the substantive evidence being presented against defendant. See Fair,
Even assuming admission of Ray’s expert opinion violated defendant’s rights under the Confrontation Clause, the alleged error was harmless, providing a separate, adequate, and independent state law ground for the judgment of the Court. “When violations of a defendant’s rights under the United States Constitution are alleged, harmless error review functions the same way in both federal and state courts.” Lawrence,

REVERSED.
Notes
. The dissenting opinion would adopt the four-part analysis set out in State v. Brewington,
. The dissenting opinion argues Agent Ray “testified to some of [the] contents” of the report written by the non-testifying analyst. As an example, the dissent writes: “[The analyst] was later asked, ‘[C]an you tell us what [the original analyst’s] result appears to have been?’ She answered, ‘[0]n the color test, it has a positive sign with a circle around it and then says blue underneath that.’ ” The dissenting opinion fails to note, however, that this testimony was elicited by defendant’s attorney on cross-examination — not by the State. Further, defendant objected only when the prosecution asked Ray, “What is your independent expert opinion?” “Generally speaking,
. Viewing the separate opinions in Williams v. Illinois in their totality, we suggest that prosecutors err on the side of laying a foundation that establishes compliance with Rule of Evidence 703, as well as the lab’s standard procedures, whether the testifying analyst observed or participated in the initial laboratory testing, what independent analysis the testifying analyst conducted to reach her opinion, and any assumptions upon which the testifying analyst’s testimony relies.

The Supreme Court declined to announce a complete definition of “testimonial” in Crawford. Id. at 68,
In Bullcoming, the Supreme Court then addressed the next logical question flowing out of Melendez-Diaz, specifically
*17 whether the Confrontation Clause permits the prosecution to introduce a forensic laboratory report containing a testimonial certification — made for the purpose of proving a particular fact — through the in-court testimony of a scientist who did not sign the certification or perform or observe the test reported in the certification.
Id. at_,
But surrogate testimony of the kind [the testifying expert] was equipped to give could not convey what [the testing analyst] knew or observed about the events his certification concerned, i.e., the particular test and testing process he employed. Nor could such surrogate testimony expose any lapses or lies on the certifying analyst’s part.
Id. at _.,
In the Williams plurality opinion, Justice Alito noted that the Court’s conclusion to allow the testimony of the DNA expert
*19 is entirely consistent with Bullcoming and Melendez-Diaz. In those cases, the forensic reports were introduced into evidence, and there is no question that this was done for the purpose of proving the truth of what they asserted: in Bullcoming that the defendant’s blood alcohol level exceeded the legal limit and in Melendez-Diaz that the substance in question contained cocaine. Nothing comparable happened here.
Id. at_,
Were there any indication in the record that Agent Ray did “independent analysis,” I could perhaps agree with the majority. There is none. She testified on direct examination, based entirely on her review of tests and notes by Agent Mills:
Q. And for trial today were you asked to review the chemical analysis that was performed on Item Number 9, control number 16826?
A. Yes, I did.
Q. When you conducted this peer review, specifically what documents did you review?
A. I reviewed the drug chemistry worksheet or the lab notes that the analyst wrote her notes on and the data that came from the instrument that was in the case file and then I also reviewed the data that was still on the instrument and made sure that was all there too.
She then responded that, based upon this review, her “independent opinion” was that the substance “was cocaine.” But, on cross-examination she testified, among other things, to the following:
Q. All right. Now just to go back to the beginning, you have done no testing of your own on Item Number 9; correct?
*20 A.. No, I have not.
Q. And so any opinions you give in court about the nature of this substance are based entirely on testing done by someone else?
A. Correct.
Q. And you were not present when those tests were performed, were you?
A. No, I was not.
Q. And you didn’t even work there until approximately two years later; correct?
A. Correct.
She acknowledged repeatedly that she could not personally verify anything about the way the tests were done and said, “I only know of what’s on the drug worksheet,” and “I can only say according to the worksheet.” “[T]he [Confrontation] Clause does not tolerate dispensing with confrontation simply because the court believes that questioning one witness about another’s testimonial statements provides a fair enough opportunity for cross-examination.” Bullcoming,_ U.S. at_,
As stated above, having implicitly acknowledged that the report was testimonial and knowing the testing analyst was absent, the majority asserts that Agent Ray offered an independent opinion on the identity of the substance tested based on the lab reports. As I understand the opinion, the only “evidence” the majority points to in support of this holding is the questioning by the State at trial. Agent Ray was asked, “What is your independent expert opinion?” She answered that “the substance was cocaine.” However, careful review of the testimony, both on direct and cross-examination, demonstrates that her opinion was in no way independent — all her knowledge and opinions about the testing process and the substance were based entirely on the review and analysis by Agent Mills, who had left the
The majority states that “[a]s part of her review, Ray analyzed the ‘reviewable data’ generated by the GCMS machine. Ray testified that the machine internally records the data, and there is no way to make alterations to what is recorded.” (Emphasis added.) The majority fails to consider how the original testing analyst may have handled or altered the substance before it was placed in the machine, or how it was entered into the machine. “Forensic evidence is not uniquely immune from the risk of manipulation.” Melendez-Diaz,
Confrontation is one means of assuring accurate forensic analysis. While it is true, as the dissent notes, that an honest analyst will not alter his testimony when forced to confront the defendant, the same cannot be said of the fraudulent analyst. Like the eyewitness who has fabricated his account to the police, the analyst who provides false results may, under oath in open court, reconsider his false testimony. And, of course, the prospect of confrontation will deter fraudulent analysis in the first place.
Confrontation is designed to weed out not only the fraudulent analyst, but the incompetent one as well. Serious deficiencies have been found in the forensic evidence used in criminal trials. . . . Like expert witnesses generally, an analyst’s lack of proper training or deficiency in judgment may be disclosed in cross-examination.
Id. at 318-19,
The majority also states that “the testifying expert was the witness whom the defendant had the right to confront. Defendant was able to cross-examine Ray fully concerning all aspects of her testimony.” But the United States Supreme Court has stated that “the [Confrontation] Clause does not tolerate dispensing with confrontation simply because the court believes that questioning one witness about another’s testimonial statements provides a fair enough opportunity for cross-examination.” Bullcoming,_U.S. at_,
The majority correctly states that “raw, machine-generated data” are neither hearsay nor testimonial. The majority relies heavily on the fact that Agent Ray looked at such “raw, machine-generated data” when forming her allegedly independent opinion. In doing so, the majority oversimplifies Agent Ray’s review process and testimony and glosses over the portions that most clearly implicate the Confrontation Clause. Agent Ray did not simply look at graphs produced from machines and testify to those results. Rather, she testified:
Q. When you conducted this peer review, specifically what documents did you review?
A. I reviewed the drug chemistry worksheet or the lab notes that the analyst wrote her notes on and the data that came from the instrument that was in the case file and then I also reviewed the data that was still on the instrument and made sure that was all there too.
Immediately after this exchange, Agent Ray was asked to “list the tests that were conducted on the substance in control number 16826[.]” She responded, “A color test was performed, a melting point
Further, even if she had only relied on raw data in forming her opinion, Agent Ray’s expert opinion would be relevant only if the State provided the foundation for the data, such as how the data were generated — a foundation that would presumably require testimony from the nontestifying analyst anyway. See Williams,_U.S. at_,
Agent Ray’s testimony is also legally insufficient to prove that the substance was cocaine because her opinion was based on assumptions that the substance was properly logged and handled, the tests properly conducted, and the results properly recorded. Effectively, her opinion is “(/'everything was done properly, and if the report is accurate, then the substance is cocaine.” Without other evidence to confirm those assumptions, there is no actual proof that defendant possessed cocaine.
While the majority acknowledges that the North Carolina Rules of Evidence “must comport with constitutional requirements,” the substance of its opinion does not follow that mandate. Instead, the majority opinion relies heavily on the Rules of Evidence, which are irrelevant to the determination of whether defendant’s Confrontation Clause rights have been violated.
Finally, the majority has failed to set out a clear framework for lower courts to use in analyzing this type of complicated, fact-specific Confrontation Clause question. Part of our charge as a Court is to provide guidance to lower courts; thus, I have set out a methodical approach for cases in which an expert witness testifies about the results of a lab report, regardless of whether the underlying report is ultimately admitted into evidence. Viewing recent United States Supreme Court precedent as a whole, I apply a four-part analysis to address these types of cases.
First, we determine whether the underlying lab report is testimonial — if it is not, there is no Confrontation Clause violation. Compare Bullcoming,_U.S. at_, 131 S-. Ct. at 2217 (rejecting the prosecution’s argument that the lab reports were not testimonial because, according to the Court, “[a] document created solely for an ‘evidentiary purpose,’... made in aid of a police investigation, ranks as testimonial”), with Williams,_ U.S. at_,
Third, if the testifying analyst is relying on another analyst’s reports, we decide whether the testifying expert offered an independent opinion based on the lab report or merely acted as a surrogate witness. The decision in Bullcoming appears to leave room for an expert who did not conduct the testing in question to offer an “independent opinion” on the fact at issue. See_U.S. at_,
Fourth, we decide whether any error is reversible, applying the appropriate standard of review.
In applying that structure for analysis here, I would hold that: (1) the lab report underlying Agent Ray’s statements was testimonial; (2) Agent Ray did not personally conduct the testing on the cocaine sample, and the State has not shown that the testing analyst (Mills) was unavailable and that defendant had a prior opportunity to cross-examine; (3) Agent Ray offered no independent opinion based on the lab report, merely communicating to the jury the lab report’s contents under the guise of an expert opinion; and (4) the error was not harmless beyond a reasonable doubt.
Further, in its harmless error analysis the majority misapplies State v. Nabors,
Here the entire prosecution of defendant depends on Agent Ray’s testimony to prove that the substance was cocaine. Without her testimony all that remains is an uncorroborated assertion by an officer on
This case can be summarized quite simply: Agent Ray provided the only substantive evidence about the central issue in the case — the identity of a chemical substance found in defendant’s possession— based entirely on test results produced and reported by another analyst (Agent Mills), whom defendant had no opportunity to cross-examine. As such, he had no way to question the reliability of the process by which those test results were obtained. Under Crawford, Melendez-Diaz, Bullcoming, and Williams, this is a quintessential Sixth Amendment violation. “The Confrontation Clause may make the prosecution of criminals more burdensome, but that is equally true of the right to trial by jury and the privilege against self-incrimination. The Confrontation Clause — like those other constitutional provisions — is binding, and we may not disregard it at our convenience.” Melendez-Diaz,
. The independence, or lack thereof, of the testifying expert’s opinion is only relevant to the Confrontation Clause analysis if it is first established that the lab report underlying the expert’s testimony is itself testimonial (it is) and that the analyst who prepared the report did not testify (she did not).
. Before reaching the “dispositive issue,” the majority addresses procedure and concludes that defendant has not adequately objected to the admission of Ray’s testimony, which it says should be reviewed for plain error. In my opinion, this discussion, and any effort to couch this case in terms of plain error, is entirely misplaced. The State did not argue that review here should be for plain error; its argument heading in the brief is: “The Court of Appeals erred by finding any error was not harmless beyond a reasonable doubt.” The argument then addresses what it appropriately notes is the proper standard for review of alleged constitutional error. Moreover, the State has not contended that the issue was not adequately preserved. Indeed, the trial court, at defendant’s request, conducted voir dire on the admissibility of the testimony and reports and ruled the reports out, but found the testimony allowable. On direct examination, at the only point the witness was asked for an “opinion,” defense counsel objected. After the testimony was admitted and cross-examined, defense counsel moved to strike the expert’s testimony, and the transcript reveals several pages of colloquy before the motion to strike was denied. As such, defendant has preserved as well as he could the one issue that matters here, to wit, Agent Ray’s opinion (based on another’s testing) that the substance was cocaine.
. Though the majority acknowledges the split opinion in Williams, the majority still appears to ascribe precedential value to the plurality opinion, classifying it as the narrowest grounds among the concurring opinions. I disagree. Neither the plurality’s reasoning nor Justice Thomas’s concurrence is narrower; they are simply different. Justice Thomas agreed with the plurality that the report was not testimonial, but for a different reason — insufficient formality. On the other hand, he agreed with the four dissenters that the Cellmark report was offered for the truth of the matter asserted therein. Thus, I believe the only firm conclusions we can draw from Williams are that the lab report there was not testimonial and that five justices agreed it was offered for its truth. These conclusions appear to apply only to the precise facts in Williams. Because it is clear that the lab report here was testimonial, as well as offered for its truth, Williams gives us little additional guidance.
. In North Carolina recent events have proved that these concerns about forensic testing are more than just mere speculation. See Chris Swecker & Michael Wolf, An Independent Review of the SBI Forensic Laboratory 4 (2010) ("This report raises serious issues about laboratory reporting practices from 1987-2003 and the potential that information that was material and even favorable to the defense of criminal charges filed was withheld or misrepresented.”); see also Paul C. Giannelli, The North Carolina
