OPINION
{1} This case requires us to decide whether the Rules of Criminal Procedure for the District Courts authorized the trial court to sever Defendant’s trial from that of his co-defendant, and then, after jury selection was completed in the co-defendant’s ease, to re-consolidate the trials at Defendant’s request. As we explain below, this procedure runs afoul of Rule 5-612 NMRA 2000 (1972, as amended through 1974), which prohibits the commencement of a criminal trial in the defendant’s absence. Because a defendant’s absence at the commencement of his trial is a non-waivable, structural defect, we reverse Defendant’s convictions.
BACKGROUND
{2} Defendant, and a co-defendant, Miguel Gallegos, were each indicted on two counts of aggravated battery with a deadly weapon and a single count of concealing identity. Defendant and Gallegos were joined for trial. On the morning of July 6,1998, Defendant and Gallegos’ case and another unrelated case were called for jury selection. Defendant’s attorney and the prosecutor were present, but Defendant, Gallegos, and Gallegos’ attorney were absent. In response to questioning by the trial court, Defendant’s counsel responded that he did not know Defendant’s whereabouts and that he had unsuccessfully attempted to locate Defendant by telephone. The trial court issued a bench warrant for Defendant’s arrest and cited Gallegos and Gallegos’ counsel for contempt.
{3} A panel of prospective jurors was sworn and voir dire commenced in the unrelated case. As voir dire in the unrelated case *627was proceeding, counsel for Gallegos appeared. He explained that he had been delayed because he had been waiting for Gallegos to fax him a written waiver of Gallegos’ right to be present during jury selection. Counsel explained that he now had the writ-, ten waiver and tendered it to the court.;
{4} The trial court remarked that it had' “a real problem with Mr. Padilla [Defendant] not being here and having the other co-defendant not present and going through [jury] questioning.” The trial court expressed a preference for waiting until Defendant had been re-arrested and rescheduling “the whole thing together” rather than proceeding with a “de facto severance.” The State responded that it preferred to accept a severance and proceed with Gallegos’ trial. Counsel for Gallegos responded that he did not see a problem in continuing with jury selection in view of his Ghent’s signed waiver of his right to be present during jury selection. The trial court ruled that the parties would proceed with jury selection in Gallegos’ case.
{5} Prior to the lunch recess, jury selection was completed in the unrelated case. Following the lunch recess, Defendant briefly appeared in the courtroom without counsel. The trial court addressed Defendant, explaining that the court had issued a bench warrant for Defendant’s arrest due to his failure to appear when his case was called that morning. The trial court commented that “this afternoon we can’t find your attorney.” The trial court told Defendant that it would hold the bench warrant until the following morning and directed Defendant to appear at 8:30 a.m. the next day. The trial court then told Defendant that he was “free to go.”
{6} The trial court called Gallegos’ case for jury selection. The trial court explained to the jury array that Gallegos had waived his right to be present at jury selection. The trial court then read into the record Gallegos’ waiver of his right to be present. The trial court explained the nature of the case to the jury array and reminded them that they were still under oath. The trial court explained that the selection process would be the same as it was in the morning except that it should be quicker because “many of the questions are the same.” Jury selection proceeded in Gallegos’ case, and by the end of the day a petit jury had been impaneled to try Gallegos.
- {7} The next morning, both Defendant and counsel were present in court. The trial court informed Defendant and his counsel that Defendant’s and Gallegos’ cases had been severed for trial. Defendant’s counsel explained that Defendant had been confused by conflicting information as to the date jury selection was to begin and had relied on a scheduling order listing July 7, 1998, as the date jury selection was to begin. Instead of accepting the severance of Defendant’s and Gallegos’ trials, Defendant’s counsel offered to waive Defendant’s presence during jury selection in view of his “faith” in the ability of Gallegos’ counsel to pick a jury. The trial court cautioned Defendant’s counsel that the Defendants’ defenses could diverge at trial and that Defendant would then be tried in "front of a jury picked by Gallegos’ counsel. •The trial court directed Defendant’s counsel to file a written waiver by 5:00 p.m. that day.
;{8} In furtherance of the procedure suggested by Defendant’s counsel and adopted by the trial court, Defendant and his counsel signed a document titled “Waiver of Jury Selection Irregularities” containing the following recitals:
COMES NOW Defendant CHRIS PADILLA and files this Waiver of Jury Irregularities, and in support of said waiver hereby states:
1) Defendant was not present for jury selection due to his uncertainty about the date of jury selection.
2) Defendant’s counsel appeared initially for jury selection but did not return for completion of jury selection when Defendant failed to appear;
3) Co-defendant’s attorney Mr. Dan Marlowe completed jury selection on behalf of his client;
4) Defendant Chris Padilla hereby waives his and his counsel’s appearance at jury selection and requests to proceed to the evidentiary phase of trial with the jury as selected by co-defendant’s counsel. Defendant Chris Padilla also waives any *628issue on appeal regarding this irregularity in the selection of the jury in his case.
{9} The case proceeded to trial at which Defendant and Gallegos were each convicted of two counts of aggravated battery. Gallegos was also convicted of one count of concealing identity.
DISCUSSION
{10} At common law “‘[i]n felonies, it is not in the province of the prisoner, either by himself or by his counsel, to waive the right to be personally present during the trial.’ ” Territory v. Lopez, 3 N.M. 156, 164, 2 P. 364, 367 (1884) (quoting 1 Bishop on Criminal Procedure § 686 (3d ed.)); see also Crosby v. United States, 506 U.S. 255, 259, 113 S.Ct. 748, 122 L.Ed.2d 25 (1993) (collecting authorities). In Diaz v. United States, 223 U.S. 442, 455, 32 S.Ct. 250, 56 L.Ed. 500 (1912), the United States Supreme Court noted and applied a limited exception to the requirement that the defendant be present at all stages of trial:
if, after the trial has begun in his presence, [defendant] voluntarily absents himself, this does not nullify what has been done or prevent the completion of the trial, but, on the contrary, operates as a waiver of his right to be present and leaves the court free to proceed with the trial in like manner and with like effect as if he were present.
(Emphasis added). The Diaz exception is incorporated in Rule 43 of the Federal Rules of Criminal Procedure. See Crosby, 506 U.S. at 260-261, 113 S.Ct. 748. Federal Rule 43 provides as follows:
(a) Presence Required. The defendant shall be present at ... every stage of the trial including the impaneling of the jury and the return of the verdict ... except as otherwise provided by this rule.
(b) Continued Presence Not Required. The further progress of the trial to and including the return of the verdict ... will not be prevented and the defendant will be considered to have waived the right to be present whenever a defendant, initially present, ...
(1) is voluntarily absent after the trial has commenced.
(1946, as amended through 1987) (emphasis added).
{11} Federal Rule 43 clearly is the model for the parallel New Mexico rule of criminal procedure in effect at the time of Defendant’s trial:
A. Presence Required. The defendant shall be present at ... every stage of the trial including the impaneling of the jury and the return of the verdict ... except as otherwise provided by this rule.
B. Continued Presence Not Required. The further progress of the trial, including the return of the verdict, shall not be prevented and the defendant shall be considered to have waived his right to be present whenever a defendant, initially present:
(1) voluntarily absents himself after the trial has commenced.
Rule 5-612 (emphasis added).
{12} Although Rule 5-612 and subsequent cases have modified the common law as set out in Lopez, see Hovey v. State, 104 N.M. 667, 671-72, 726 P.2d 344, 349 (1986) (Walters, J., specially concurring; discussing retreat from “early and intractable” position of Lopez), Lopez has never been expressly overruled. In particular, no New Mexico case has held that a trial court has the authority to begin a criminal trial in the defendant’s absence.
{13} The question of whether a trial may begin in the defendant’s absence was addressed by the United States Supreme Court in the context of Federal Rule 43 in Crosby. Crosby involved a defendant facing federal mail fraud charges who fled the night before his trial was scheduled to begin. After unsuccessful efforts to locate the defendant, the trial court proceeded to trial over the objections of the absent defendant’s counsel. The absent defendant and two co-defendants who were present were found guilty by the jury. Ultimately, the absent defendant was apprehended and sentenced. On appeal to the Eighth Circuit Court of Appeals, the defendant argued that Federal Rule 43 prohibits the trial in absentia of a defendant who is not *629present at the beginning of trial. The Court of Appeals rejected this argument and affirmed. The Supreme Court granted certiorari and reversed.
{14} The Supreme Court emphasized that Federal Rule 43(a) expressly states that the defendant shall be present “except as otherwise provided by this rule.” Crosby, 506 U.S. at 258-59, 113 S.Ct. 748. Thus, in view of the express language of Subsection (a), the defendant’s trial could have proceeded in the defendant’s absence only if authorized by Rule 43. However, the exceptions recognized in Subsection (b) could not apply because the defendant had not been “initially present” as required by Subsection (b). The Supreme Court held that “[t]he language, history, and logic of Rule 43 support a straightforward interpretation that prohibits the trial in absentia of a defendant who is not present at the beginning of trial.” Crosby, 506 U.S. at 262, 113 S.Ct. 748. The Supreme Court emphasized that its holding was based on the language of Rule 43 and that 'therefore it was not reaching the issue of whether the same result would be required by the Constitution. See id.
{15} Subsequently, the Supreme Court has stated that Crosby is an exception to the general principle that the procedural requirements of the Federal Rules of Criminal Procedure are “presumptively waivable.” United States v. Mezzanatto, 513 U.S. 196, 201, 115 S.Ct. 797, 130 L.Ed.2d 697 (1995). According to the Supreme Court, the presumption of waivability can be overcome where an express waiver clause indicates that the drafters “intended to occupy the field and to preclude waiver under other, unstated circumstances.” Id. at 201-02, 115 S.Ct. 797. Rule 43 presents a situation where “waiver is not appropriate [because] it is inconsistent with the provision creating the right sought to be secured.” New York v. Hill, 528 U.S. 110, 116, 120 S.Ct. 659, 664-65, 145 L.Ed.2d 560 (2000) (distinguishing Crosby).
{16} We are persuaded by the Supreme Court’s analysis of Federal Rule 43. As noted above, Rule 5-612 is closely patterned on Federal Rule 43. New Mexico common law establishing the non-waivability of the defendant’s presence appears to be identical with federal common law discussed in Crosby. Compare Lopez, 3 N.M. at 163-165, 2 P. at 367, with Crosby, 506 U.S. at 259, 113 S.Ct. 748.
{17} We recognize that the present case is distinguishable from Crosby in that here, Defendant was absent from only a single phase of his trial — jury selection — and that Defendant and his counsel attempted to retroactively waive Rule 5-612’s requirements. In contrast, in Crosby, the defendant was absent from his entire trial and the trial was conducted over the objections of defense counsel. We find these distinctions immaterial because under Rule 5-612(B), just as under Federal Rule 43, a defendant’s presence can be waived only if he was “initially present.” As we recently observed, a jury trial commences when jury selection begins. See State v. Rackley, 2000-NMCA-027, ¶ 4, 128 N.M. 761, 998 P.2d 1212. Considering that Defendant was not present when his cáse was called on the morning of July 6, 1998, when the jury array was sworn or during voir dire of the jury that ultimately tried him, he cannot be said to have been “initially present” within the spirit or the letter of Rule 5-612. See United States v. Stratton, 649 F.2d 1066, 1081 (5th Cir.1981) (noting that trial court’s use of bifurcated trial procedure could not mask realities of trial and that defendant was “for all practical purposes” on trial despite severance; holding that severed defendant was denied his constitutional and Rule 43 right to be present at all stages of his trial); State v. Crafton, 72 Wash.App. 98, 863 P.2d 620 (1993) (applying Crosby as adopted by Washington Supreme Court in State v. Hammond, 121 Wash.2d 787, 854 P.2d 637 (1993); holding that for purposes of rule of criminal procedure allowing trial to continue where defendant has voluntarily absented himself, trial commences when jury panel is sworn for voir dire), review denied, 123 Wash.2d 1030, 877 P.2d 695 (1994).
. {13} We hold that under these facts, Rule 5-612 did not authorize the trial court to accept a retroactive waiver of Rule 5-612’s requirement that Defendant be present at the commencement of his trial. In the ab*630sence of a waiver expressly authorized by Rule 5-612, Defendant’s case is governed by the common-law rule that in felony trials the defendant’s presence is a mandatory, nonwaivable requirement.1 See Pelaez v. United States, 27 F.3d 219, 222 (6th Cir.1994) (Fed. Rule 43 “is the common law rule as modified by Diaz.”); State v. Hunt, 26 N.M. 160, 166, 189 P. 1111, 1113 (1920) (collecting authorities).
{19} Next, we consider whether Defendant’s absence can be excused as harmless error. Generally, harmless error analysis requires this Court to determine whether there is a “reasonable possibility” that the error complained of contributed to the defendant’s conviction. See State v. Trujillo, 95 N.M. 535, 541, 624 P.2d 44, 50 (1981). This mode of harmless error analysis is applied where the procedural requirement determined to have been violated is thought to contribute to the reliability of the truth-finding process. See 3 Wayne R. LaFave & Jerold H. Israel, Criminal Procedure § 26.6(a) (1984). However, there are other errors that “loosely [may] be described as concerned with the structure of the proceeding.” Id. at 259. In the case of these structural errors “[N]o evaluation of the bearing of the error on the jury’s verdict is necessary. A violation of the substance of the right automatically requires a new trial, and the strength of the evidence supporting the conviction is therefore irrelevant.” Id. at 259.
{20} n the present ease, the specific requirement with which we are concerned is Rule 5-612’s requirement that the defendant be initially present at the commencement of his or her trial. In our view, the requirement of the defendant’s initial presence at trial is largely symbolic, reflecting our society’s traditional distrust of in absentia proceedings. Justice Stevens has suggested that harmless-error analysis is inappropriate where the procedural right determined to have been violated serves “an independent value besides reliability of the outcome.” United States v. Lane, 474 U.S. 438, 474, 106 S.Ct. 725, 88 L.Ed.2d 814 (1986) (Stevens, J., concurring in part, dissenting in part). The requirement of the defendant’s initial presence at trial serves “an independent value besides reliability of the outcome” and is akin to a structural defect. We therefore hold that a non-cte minimis violation of Rule 5-612’s requirement that the defendant be initially present constitutes reversible error without regard to whether the defendant’s absence actually contributed to an unfavorable verdict.
{21} Defendant’s convictions are reversed and this case is remanded for a new trial.
{22} IT IS SO ORDERED.
