COURT OF APPEALS OF VIRGINIA

Present: Judges Elder, Frank and Haley Argued at Chesapeake, Virginia

KELLUP LAMONTE BROOKS OPINION BY v. Record No. 2195-05-1 JUDGE LARRY G. ELDER DECEMBER 19, 2006 COMMONWEALTH OF VIRGINIA

FROM THE CIRCUIT COURT OF THE CITY OF NORFOLK John C. Morrison, Jr., Judge Charles E. Jenkins, II, for appellant. Leah A. Darron, Senior Assistant Attorney General (Robert F. McDonnell, Attorney General; Karri B. Atwood, Assistant Attorney General, on brief), for appellee.

Kellup Lamonte Brooks (appellant) appeals from his jury tr ial conviction for possession of cocaine with intent to distribute. On appeal , he contends the trial court erred in admitting the certificates of analysis establishi ng that some of the substances se ized at the time of his arrest on an unrelated offense were cocaine. He argues the certificates contained hearsay considered testimonial under Crawford v. Washington , 541 U.S. 36, 124 S. Ct. 1354, 158 L. Ed. 2d 177 (2004), and, thus, that admitting them without ha ving the forensic analyst present to testify, although permitted by Code § 19.2-187 as an excep tion to state hearsay rules, violated his Confrontation Clause rights. Assuming without deciding the certificates contained information

considered testimonial under Crawford , we hold the procedure in Code §§ 19.2-187 and- 2 - 19.2-187.1 adequately protects a defendant ’s Confrontation Clause rights. 1 Thus, we affirm appellant’s conviction.

I.

BACKGROUND On June 16, 2004, narcotics investigators arre sted appellant in a motel room in which they found several different quant ities of suspected cocaine, cas h, and paraphernalia associated with drug distribution. Appellant was charged, inter alia , with possession of cocaine with intent to distribute. Appellant was indicted for that offense on September 1, 2004. On September 21, 2004, more than seven days prior to trial, as required by the hearsay exception provision of Code § 19.2-187, the Comm onwealth filed certificates of analysis confirming that several of the items seized were cocaine or contained coca ine or heroin residue. By letter of October 22, 2004, in response to appella nt’s motion for discovery and with a copy of the letter to the court, the Co mmonwealth provided appellant’s c ounsel with copies of those certificates of analysis, expressl y indicating they were being “provided in accordance with the Code of Virginia § 19.2-187.” At trial on August 24, 2005, appellant moved to exclude the certificates of laboratory analysis of the drugs, 2 claiming that the Commonwealth’s failure to call the forensic scientist

who tested the substances deni ed him his constitutional right to confrontation under Crawford

. The Commonwealth responded that Code § 19.2-1 87.1 provides a mechanism giving a defendant

1 We do not consider the constitutionality of the order of proof allowed by Code § 19.2-187.1 because that issue is not properl y before us in this appeal. See infra text accompanying note 6.

2 Appellant also moved to ex clude a certificate of DNA analys is involving a firearm, but the admission of that certificate is not at issu e in this appeal. Appe llant did not object to admission of a certificate of anal ysis covering suspected drugs f ound in the possession of another person in the motel room at th e time of appellant’s arrest.- 3 - “the right to call the person perf orming such analysis . . . at th e cost of the Commonwealth” but that appellant had not notified the Commonw ealth he had an objection to admitting the

certificates in the absence of the scientist. Th e Commonwealth averred that “if defense counsel had told me specifically he had any objection . . . , I would have ensured [the analyst’s] presence here today; and if [the analyst wa s] unable to be here, . . . I woul d have requested a continuance.” The Commonwealth argued that the provisi on of Code § 19.2-187.1 allowing a defendant to assert his right of confrontat ion in a particular manner prev ented it from running afoul of

Crawford . Appellant argued “the fact that [he] could have subpoenaed somebody because the code allows it doesn’t really answer the math b ecause that’s shifting the burden of proof to the

defendant.” The court denied the motion on two grounds . It reasoned first that Code § 19.2-187.1 provides for a right to call a pe rson who conducted an examination to have them present, if the defens e so desires. It does not shift the burden of proof. What it is, is a procedural provision that simply requires that a party do something in a timely manner.

There is no violation of the C onfrontation Clau se to require a defendant to do something or raise an issue [or] objection in advance of trial because you are ba lancing the defendant’s right to challenge evidence against the right of the public, in effect, to have an efficiently run court system that’s not bogged down by late requests and objections to evidence that, for example, leaves a jury sitting in a jury room for 35 minut es or more past lunch because we are resolving something that really should have been resolved in advance of trial, if there was a ny real meat to the objection . . . . . . . All you have to do is say, you know, I want these people present for this trial, a nd the Commonwealth would have been forced to [have them presen t]. And as [the prosecutor] has said, if [you had made such a reque st in this case], he would have been forced to request a continuan ce. . . . [T]hen if the Court had granted that request for a continua nce, the question of whether or not a speedy trial violation woul d occur and your objection [could have been addressed]. All those procedural rights and everything would be protected. The confront ation clause [rights] would be protected. . . .- 4 - The court also concluded that Crawford was inapplicable because it did not cover non-testimonial hearsay and the co urt found that reports of scient ific examination such as the certificates of drug analysis were non-testimonial. At trial, the certificates of analysis we re admitted as part of the Commonwealth’s evidence. The jury convicted appellant for possessi on of cocaine with intent to distribute, and he noted this appeal.

II.

ANALYSIS

The Confrontation Clause of the United States Constitution provides that, “In all criminal prosecutions, the accused shall enjoy the right . . . to be confronted with the witnesses against him.” U.S. Const. amend. VI. This “procedural guarantee” also “applies to state prosecutions.”

Michels v. Commonwealth , 47 Va. App. 461, 466, 624 S.E.2d 675, 678 (2006). In its 2004

decision in Crawford , the United States Supreme Court cl arified the test for “determining whether the admission of hearsay,” an out-of-cour t statement offered to prove the truth of the matter asserted, “violates the accused’s right[s] under the Confrontation Clause.” Horton v.

Allen , 370 F.3d 75, 83 (1st Cir. 2004). “[W]hen the d eclarant appears for cross-examination at trial,” stated the Court, “the Confrontation Clau se places no constraints at all on the use of his prior . . . statements.” Crawford , 541 U.S. at 59 n.9, 124 S. Ct. at 1369 n.9, 158 L. Ed. 2d at 197 n.9. However, if the declarant does not appear for trial and the statement is “testimonial” in nature, “the Sixth Amendment demands what the common law required: [proof of the] unavailability [of the declarant] and a prio r opportunity for cross-examination.” Id. at 68, 124 S. Ct. at 1374, 158 L. Ed. 2d at 203. Appellant avers the trial court erred in admitti ng the certificates of analysis establishing that the substances seized were cocaine, conten ding the certificates cont ained hearsay considered- 5 - testimonial under Crawford and, thus, that admitting them without having the forensic analyst present to testify, although permitted by Code § 19.2-187 as an exception to state hearsay rules,

violated his Confrontation Clause rights. Assuming without deci ding the certificates contained

information considered testimonial under Crawford , we hold the procedure in Code §§ 19.2-187 and 19.2-187.1 adequately protects a defenda nt’s Confrontation Clause rights. The applicable version of Code § 19.2-187 provides in relevant part as follows: In any hearing or trial of any crim inal offense . . . , a certificate of analysis of a person performing an analysis or examination, performed [in any of several speci fied laboratories] when such certificate is duly attested by such person, shall be admissible in evidence as evidence of the facts th erein stated and the results of the analysis or examination refe rred to therein, provided (i) the certificate of analysis is filed with the clerk of the court hearing the case at least seven days prior to th e hearing or trial and (ii) a copy of such certificate is [provided to counsel of record for the accused upon request made in the manner prescribed by the statute]. 2005 Va. Acts, chs. 868, 881. Code § 19.2-187.1 provides that, “in any hearing or trial in which a cert ificate of analysis is admitted into evidence pursuant to § 19.2-187,” the accused “shall have the right to call the person performing such analysis or examination . . . as a witness therein, and examine him in the

same manner as if he had been called as an adve rse witness.” That code section further provides that “[s]uch witness shall be summoned and app ear at the cost of the Commonwealth.” Code § 19.2-187.1. Manifestly, in order to compel the a ttendance of a witness at trial via the court’s subpoena power, a subpoena for that witness must be issued and served in advance of trial. 3

3 No statute or rule requires a subpoena for an appearance in circuit court be issued any particular number of days prior to trial, al though service “at least 10 da ys before trial” is recommended. See Rule 3A:12 (governing procedure for compelling attendance of witnesses in criminal trials in circuit courts but not specif ying number of days in advance of trial by which subpoenas should or must be issued); Sup. Ct. Rules Part 1, Form 3 (providing in Uniform Pretrial Scheduling Order pursuant to Rule 1:18 B that “Early filing of a request for witness subpoenas is encouraged so that su ch subpoenas may be served at leas t 10 days before trial”); cf. Shifflett v. Commonwealth , 218 Va. 25, 30, 235 S.E.2d 316, 319-20 (1977) (holding defendant- 6 - Here, because appellant failed to notify the Co mmonwealth or the trial court of his desire to confront the preparer of the certificates of dr ug analysis until the day of trial, appellant failed properly to avail himself of the protections of Code § 19.2-187.1. We hold, as have other courts interpreting similar statutes, that this failure co nstituted a simultaneous waiver of any right he may have had under the Confrontation Clause to cross-examine the preparer of the certificates. The right of an accused to confront and cr oss-examine is “‘not absolute and may, in appropriate cases, bow to accommodate other legitimat e interests in the criminal trial process.’” Baugh v. Commonwealth , 14 Va. App. 368, 371, 417 S.E.2d 891, 893 (1992) (quoting Chambers v. Mississippi , 410 U.S. 284, 295, 93 S. Ct. 1038, 1046, 35 L. Ed. 2d 297, 309 (1973)). “It has [also] long been recognized that a defendant ma y voluntarily waive the ri ght to confront[ation] . . . .” State v. Cunningham , 903 So. 2d 1110, 1120 (La. 2005) (citing Diaz v. United States , 223 U.S. 442, 450, 32 S. Ct. 250, 252, 56 L. Ed. 500, 503 (1912)). [T]he right may be waived by a guilty plea, Boykin v. Alabama , 395 U.S. 238, 89 S. Ct. 1709, 23 L. Ed. 2d 274 (1969), by a defendant’s disruptive conduct in the courtroom, Illinois v. Allen , 397 U.S. 337, 90 S. Ct. 1057, 25 L. Ed. 2d 353 (1970), by a defendant’s voluntary absence from trial, Taylor v. United States , 414 U.S. 17, 94 S. Ct. 194, 38 L. Ed. 2d 174 (1973), and by a defendant’s intimidation of a grand jury witness from testifying at trial, United States v. Carlson , 547 F.2d 1346 (8th Cir. 1976), cert. denied , 431 U.S. 914, 97 S. Ct. 2174, 53 L. Ed. 2d 224 (1977).

Bilokur v. Commonwealth , 221 Va. 467, 472, 270 S.E.2d 747, 751 (1980). The Virginia Supreme Court has also held that a defenda nt may, through counsel, waive his right to confrontation by stipulating to the us e of a witness’ pr ior testimony. Id. at 473-74, 270 S.E.2d at 751-52 (adopting “as the rule in Virginia” that counsel for a criminal defendant may, under certain circumstances, “‘waive his client’s Sixth Amendment right of confrontation by

not entitled to continuance based on unavailabil ity of witness because attempt to subpoena witness only two days before trial did not constitute due diligence).- 7 - stipulating to the admission of eviden ce’” (quoting United States v. Stephens , 609 F.2d 230, 232-33 (5th Cir. 1980))). 4 It is also “beyond question that under th e Due Process Clause of the Fourteenth Amendment [a state] may attach reasonable ti me limitations to the assertion of federal constitutional rights.” Michel v. Louisiana , 350 U.S. 91, 97, 76 S. Ct. 158, 162, 100 L. Ed. 83, 91 (1955). “A state procedur al rule which forbids the raising of federal questions at late stages in

4 The holding in Bilokur does not require that a defenda nt be given an opportunity, on the record, expressly to accept or reject his attorney’s confront ation waiver. 221 Va. at 473, 270 S.E.2d at 751-52. It provides merely that such a waiver is not valid if the defendant’s lack of consent is apparent in the record. Id. The holding in Bilokur is consistent with the ho lding in Brookhart v. Janis , 384 U.S. 1, 86 S. Ct. 1245, 16 L. Ed. 2d 314 (1966), on which it relied in part. Brookhart involved the “knowing agree[ment]” of a defenda nt’s attorney to “a prima facie trial,” a proceeding in which “the State need make only a prima facie showing of guilt” and in which the defendant agrees to “neither offer evidence on [his] behalf nor cro ss-examine any of the State’s witnesses.” Id. at 6-7, 86 S. Ct. at 1248, 16 L. Ed. 2d at 318-19. Im mediately after the at torney’s statement, however, the defendant unequivocally said, “‘I would like to point out in no way am I pleading guilty to this charge,’” which the Court held negated his attorney’s prior agreement to a prima facie trial. Id. The Supreme Court held this sequence of events “narrow[ed]” the question on appeal “to whether counsel has th e power to enter a plea which is inconsistent with his client’s expressed desire and thereby waive his client’s constitutio nal right to plead not guilty and have a trial in which he can confront and cross-examine the witnesses against him.” Id. at 7, 86 S. Ct. at 1248, 16 L. Ed. 2d at 319 (emphasis added). The Court held that “the constitutional rights of a defendant cannot be waived by his counsel under such circumstances .” Id. (emphasis added). The Court noted its ongoing recognition of the principle “that counsel may, under some conditions, where the circumstances are not ‘exceptional, preclude the accused from asserting constitutional claims,’” but it held that this principle did not allow an attorney to “override his client’s desire expressed in open court to plead not guilty.” Id. at 7-8, 86 S. Ct. at 1248-49, 16 L. Ed. 2d at 319 (quoting Henry v. Mississippi , 379 U.S. 443, 451, 85 S. Ct. 564, 569, 13 L. Ed. 2d 408, 414-15 (1965) (empha sis added)); see also, e.g. , Stephens , 609 F.2d at 232-33 & n.2 (holding counsel’s stipulation to facts without expres s consent of accused is valid as long as stipulation is not “tantamount to a guilty plea”), cited with approval in Bilokur , 221 Va. at 473, 270 S.E.2d at 751-52; Symons v. Klinger , 372 F.2d 47, 49-50 (9th Cir. 1967) (holding waiver of defendant’s right to confr ontation valid under Brookhart “without [defendant’s] personal waiver and consent” where defendant’s attorney fu lly cross-examined government witnesses at preliminary hearing, mounted “vigorous defense . . . based largely upon . . . [c]onstitutional issues” via pre-trial motion to suppress, and then s tipulated to use of “reco rd made at preliminary hearing in lieu of trial”). Appellant raised no claim at tr ial or on appeal that his couns el could not va lidly waive his right of confrontation. Thus, we do not cons ider this issue furt her in this appeal.- 8 - the case, or by any other than a prescribed met hod, has been recognized as a valid exercise of state power.” Williams v. Georgia , 349 U.S. 375, 382-83, 75 S. Ct. 814, 819, 99 L. Ed. 1161, 1170 (1955). Under Code § 19.2-266.2, for example, absent “good cause shown,” an accused seeking to exclude evidence he contends was gather ed in violation of his Fourth, Fifth, or Sixth Amendment rights waives the opport unity to raise such a claim if he does not file a written motion to suppress at least seven days before tr ial. That code section contains a related subdivision addressing a defendant’s claim that charges against him are based on an unconstitutional statute and provides that failure to raise such a claim in a timely fashion also

constitutes a waiver. See Johnson v. Commonwealth , 37 Va. App. 634, 644-45, 561 S.E.2d 1, 6 (2002). Similarly, we hold Code § 19.2-187.1 sets out a reasonable procedure to be followed in

order for a defendant to exercise his right to confront a particular limited class of scientific

witnesses at trial and that a defendant’s failure to follow this procedure amounts to a waiver of the constitutional right to confront such witnesses. 5 This procedure encourages judicial and governmental economy by providing that certain scie ntific witnesses, empl oyees of the state, need not routinely be called to testify, but it pr eserves the right of a de fendant to confront any such witness as long as he notifies the Common wealth, in a specific a nd timely fashion, of his

desire to do so. The holding in Crawford , the United States Supreme C ourt’s 2004 Confrontation Clause decision, does not compel a contrary result, as appellate courts in ot her jurisdictions have decided. The Supreme Court of Louisiana, for ex ample, reached just such a result in State v.

5 We consider only the constitutionality of th e statutes at issue in this case, Code §§ 19.2-187 and 19.2-187.1, which involve admission of the results of specified categories of scientific “analysis or examination,” and do not decide the constitutionality of similar statutes that may involve other categories of evidence.- 9 - Cunningham , 903 So. 2d 1110 (La. 2005). Pursuant to the statute at i ssue in Cunningham , if the prosecutor provided a defendant with a copy of the certificate of analysis and written notice, at least ten days prior to trial, of his intent to offe r the certificate into eviden ce at trial, the court was required, subject to certain exceptio ns, to admit the certificate “as prima facie proof of the facts shown thereon, and as prima facie proof of [the chain of] custody of the physical evidence.” Id. at 1115 (citing La. Rev. Stat. Ann. § 15:501). The statute provided the certificate would not serve as prima facie proof if “the party agai nst whom the certificate is offered requests a subpoena for the person performing the analysis at least five days before trial” or “‘the person subpoenaed responds to the subpoena.’” Id. (quoting La. Rev. Stat. Ann. § 15:501). The

defendant contended the statute bo th deprived him of his right to confront and cross-examine the witness and impermissibly shifted th e burden of proof to him. Id. at 1113-14. In rejecting the defendant’s arguments, the court explained: These statutes are [merely] a formalized means of effecting a stipulation to the admissibility of matters which often are not in dispute. . . . After the State ha s put the defendant on notice, the statute provides the defendant with a small procedural step which must be taken to exercise the right to confrontation. In essence, it is the defendant’s decision which dictates whether the State must produce the individual who prepar ed the report or whether the defendant will agree to use of the [analyst’s] report. . . .

* * * * * * * . . . As the State conceded at oral argument, once the defendant requests the subpoena, [t he express language of the statute provides] the certificate of analysis has no evidentiary value and the State must call the releva nt witnesses to prove its case.

Id. at 1119-21; see also City of Las Vegas v. Walsh , 124 P.3d 203, 207-08 (Nev. 2005) (en banc); State v. Campbell , 719 N.W.2d 374, 376-78 (N.D. 2006). As additional support for its reasoning, the Louisiana Supreme Court cited a recognized pro cedural step involved in a defendant’s exercising his Fourth Amendmen t rights under Louisiana law, noting that “a- 10 - defendant must file a [pre-tri al] motion to suppress in order to contest an unconstitutional search.” Cunningham , 903 So. 2d at 1121 n.11; see Code § 19.2-266.2. Oregon’s appellate courts have taken a lik e approach, holding Or egon’s statute “is a legislative decision to make what amounts to [a request to the defendant to stipulate to the contents and chain of custody of a certificate of analysis] in every . . . case.” State v. Hancock , 854 P.2d 926, 929 (Ore. 1993); see State v. Miller , 144 P.3d 1052, ____ (Ore. Ct. App. 2006) (holding reasoning in Hancock still valid after Crawford ). The Oregon statute at issue in

Hancock , which set out a procedure almost identical to Virginia’s, provided that certain reports analyzing controlled substances “‘shall be accepte d as prima facie evidence of the results of the analytical findings’” but that “‘the defendant may subpoena the [analyst] to testify at the preliminary hearing and trial . . . at no cost to the defendant.’” Hancock , 854 P.2d at 926 (quoting Or. Rev. Stat. § 475.235). Pursuant to that statute, the Court observed in Hancock , Defendant has the right to confr ont the [analyst]. . . . By its very terms, [the Oregon statute] expressly safeguards a defendant’s right to confront and cross-ex amine, “face-to-face,” the person who performed the tests. . . . If a defendant wants to cross-examine the [analyst], he or she must subpoena the [analyst]. Service of the subpoena puts the st ate on notice that the defendant wants to cross-examine the [analyst]. At trial, the state can, if it wishes, call the [analyst] to testify to the testing processes, or it can offer the report [as permitted by the statute].

Id. at 929. Similarly, we hold that, even in the wake of Crawford , Virginia’s applicable statutes, Code §§ 19.2-187 and 19.2-187.1, are merely a request to the defendant to stipulate to the admissibility of the contents of any properly fi led certificates of analysis. Where a defendant waits until trial to assert his right to cross- examine the analyst who prepared a particular certificate, he accepts the request to stipulate and waives his right to confront that witness. See John G. Douglass, Beyond Admissibility: Real C onfrontation, Virtual Cross-Examination, and- 11 - the Right to Confront Hearsay , 67 Geo. Wash. L. Rev. 191, 229 (1999) (“Properly applied, . . . a rule providing that defendants must request a subpoena to invoke the co nfrontation right should not work a serious hardship on defendants. In es sence, the rule requires that a defendant mean what he says when he asks for confrontation.”). But see State v. Smith , 2006 Ohio 1661, *P21-*P26, 2006 Ohio App. LEXIS 1555, **18-**22 (holdi ng “waiver of the confrontation right before trial must be made knowingly, intellig ently, and voluntarily” and that waiver not voluntary in Smith’s case because language on copy of certificate provided to him contained insufficient information regarding eff ect of waiver); State v. Caulfield , 722 N.W.2d 304, 312-13 (Minn. 2006) (adopting reasoning of Oh io Court of Appeals in Smith ). If the defendant does not wish to enter into such a stipulation, C ode § 19.2-187.1 provides the mechanism by which he may reject the request and have the analyst summ oned to appear at trial at the cost of the Commonwealth in order to be subj ect to cross-examination. See Crawford , 541 U.S. at 59 n.9, 124 S. Ct. at 1369 n.9, 158 L. Ed. 2d at 197 n.9 (“[W]hen the declarant appears for cross-examination at trial, the C onfrontation Clause plac es no constraints at all on the use of his prior . . . statements.”). In sum, we hold a defendant’s failure timely to notify the Commonwealth of his desire to confront the forensic analyst at trial constitutes a waiver of that right. To the extent appellant also claims the procedure in Code § 19.2-187.1 unconstitutionally placed upon him the burden of presenting evidence in order to exercise his right to call the analyst, see, e.g. , Green v. Young , 264 Va. 604, 609, 571 S.E.2d 135, 138 (2002) (recognizing due process right of accused to have Commonwealth prove every element of case agai nst him beyond reasonable doubt), we hold that question is not before us on appeal. Becau se appellant failed under Code § 19.2-187.1 to “summon[]” “the person performing [the] analys is or examination” or to ask that the Commonwealth do so, the trial court never had o ccasion to address the pr oper order of proof.- 12 - Assuming without deciding the prov isions of Code § 19.2-187.1 relati ng to the order of proof at trial could conceivably be applied in a way th at violates an accuse d’s due process rights, 6 such an application did not occur in appellant’s case. See Grosso v. Commonwealth , 177 Va. 830, 838-39, 13 S.E.2d 285, 288 (1941) (assuming without deciding statute may be applied in discriminatory fashion, “one challenging the const itutionality of a provision in a statute has the burden of showing that he himself has been injure d thereby”). Thus, we do not consider such a claim in this appeal.

6 In Hancock , the Supreme Court of Oregon narrowly interpreted a statute very similar to Virginia’s so as to protect a defendant’s due process right to have the Commonwealth prove every element of its case beyond a reasonable doubt: We interpret the statute to protect the right of a defendant, if he or she chooses, to have an opportunity to cross-examine the person conducting the analysis before the analytical report is received into evidence . If a defendant wants to cross-examine the [analyst], he or she must subpoena the [analyst]. . . . At trial, the state can, if it wishes, call the [analyst] to testif y to the testing processes, or it can offer the report [as permitted by the statute]. In either event, before the report is received in evidence, if the defendant has subpoenaed the [analyst], the defendant must be given the opportunity to cross-examine the [a nalyst]. This construction of the statute protects the defendant’s confrontation rights and avoids any confrontation problem. See State v. Jackson , 224 Or. 337, 345, 356 P.2d 495 (1960) (court has “a duty to give an act a constitutional construc tion if it can be done without wrenching the meaning of words”). 854 P.2d at 929 (emphasis added); see State v. Wells , 144 P.3d 1077, ____ (Ore. Ct. App. 2006) (holding ruling in Hancock that narrowed statutory scheme did not shift burden of proof to defendant remains good law in wake of Crawford ); see also Pamela R. Metzger, Cheating the Constitution , 59 Vand. L. Rev. 475, 525 (2006) (considering st atute that (i) presumes certificate of analysis proves “elemental fact” and (ii) pr ovides presumption “is rebuttable if, and only if, the defendant puts on a case” and op ining that such a statute “is [a] classic [example of] burden shifting in defiance of the Constitution”). The Supreme Court of Oregon eliminated pot ential constitutional problems relating to “burden shifting” by requiring th at the analyst be available for cross-examination in the prosecution’s case-in-chief.- 13 - III. For these reasons, we hold the procedur e in Code §§ 19.2-187 and 19.2-187.1, to the extent that procedure is before us in this appeal, adequately pr otects a defendant’s Confrontation Clause rights. Because appellant waived that ri ght by failing to invoke it in advance of trial, we

hold the trial court’s admission of the challenged certificates was not error on these facts, and we affirm appellant’s conviction.

Affirmed.
