**146The issue before us is whether a defendant who failed to raise a timely objection to an improper court room closure at trial nevertheless preserved the claim by raising the issue for the first time in his motion for a new trial, thirteen years after his convictions. Otherwise stated, by failing to raise the claim at trial, did the defendant "procedurally waive"1 his entitlement to the standard of review designated for preserved and meritorious **147claims of structural *359error, regardless of whether counsel and the defendant were subjectively unaware that the court room had been closed at trial? We answer the question in the affirmative: where a defendant fails to raise a timely objection to such a closure at trial, thus depriving the judge of the opportunity to either fix the error or analyze the closure under the standard set forth in Waller v. Georgia, 467 U.S. 39, 48, 104 S.Ct. 2210, 81 L.Ed.2d 31 (1984), the defendant forfeits or procedurally waives review of his or her claim under the standard designated for preserved claims of structural error.2 We emphasize that, although a defendant who fails to object to the closure at trial forfeits or procedurally waives the more favorable standard of review, the defendant does not waive the right to raise the claim. We review unpreserved court room closure claims to determine whether the improper closure created a substantial risk of a miscarriage of justice.3 Because we conclude **148that the defendant's claim was not preserved, the grant of the defendant's motion for a new trial must be reversed.

Background. In 2002, a jury in the Superior Court in Suffolk County convicted the defendant of murder in the first degree on a felony-murder theory, armed robbery, and unlawful possession of a firearm.4 Approximately thirteen years after he had been convicted, the defendant filed his first motion for a new trial, claiming that his Sixth Amendment right to a public trial had been violated because the court room had been improperly closed during jury empanelment. The defendant did not claim that his counsel had been ineffective for failing to object to the closure at trial. This was the first time that the defendant raised the claim, as his trial counsel had *360not objected to the closure at any point during trial.

Following an evidentiary hearing on the defendant's motion for a new trial, the motion judge (the trial judge having since retired) concluded that court officers had impermissibly closed the court room during jury empanelment and had excluded members of the public from entering the court room, including the defendant's family. The judge found that defense counsel did not object to the closure because neither counsel nor the defendant was aware that the court room had been closed during empanelment; the trial judge did not order the court room closure, nor was she aware of it. Defense counsel's focus on the jury selection process, according to the judge, was the reason counsel was unaware of the court room closure.

Although counsel was aware that court rooms in the Commonwealth would occasionally close during empanelment to accommodate large venires, counsel was unaware whether this was a practice in Suffolk County court rooms at the time of the defendant's trial.5 Similarly, counsel was unaware that the Sixth Amendment right to a public trial extended to jury empanelment. As a **149result, counsel stated, and the judge credited, that if he knew that the defendant's family members had been barred from the court room during jury selection, "he would have asked that they be admitted, but probably would not have made any other kind of objection."

The judge determined that because the defendant and his counsel were unaware that the court room had been closed during empanelment, counsel's failure to contemporaneously object to the closure did not constitute a procedural waiver of his Sixth Amendment public trial claim. Instead, the judge concluded that the defendant preserved his claim by raising it in his first motion for a new trial, which was filed while his direct appeal was pending in this court. The motion judge did not examine whether the defendant and counsel, as a factual matter, had an opportunity to perceive that members of the public had been excluded from the court room or that only prospective jurors were present during empanelment, or whether they otherwise should have perceived the exclusion of the public from the court room during empanelment.6 Construing the defendant's claim as a preserved structural error, the judge granted the defendant's motion for a new trial.

Discussion. The Commonwealth contends that the judge erroneously concluded that the defendant's Sixth Amendment public trial claim had not been procedurally waived despite counsel's failure to lodge a contemporaneous objection at trial to the closed court room. We agree.

We review the disposition of a motion for a new trial for "a significant error of law or other abuse of discretion." Commonwealth v. Forte, 469 Mass. 469, 488, 14 N.E.3d 900 (2014), quoting Commonwealth v. Grace, 397 Mass. 303, 307, 491 N.E.2d 246 (1986).

The Sixth Amendment right to a public trial extends to the jury selection *361process, and a violation of that right constitutes structural error. See Weaver v. Massachusetts, --- U.S. ----, 137 S.Ct. 1899, 1910, 198 L.Ed.2d 420 (2017) ; Commonwealth v. Wall, 469 Mass. 652, 672, 15 N.E.3d 708 (2014) ; Commonwealth v. Cohen (No. 1), 456 Mass. 94, 105-106, 921 N.E.2d 906 (2010). See also Presley v. Georgia, 558 U.S. 209, 213, 130 S.Ct. 721, 175 L.Ed.2d 675 (2010). It is similarly **150well settled that "[w]here a defendant timely raises and preserves a meritorious claim of structural error, this court 'will presume prejudice and reversal is automatic.' " Commonwealth v. Jackson, 471 Mass. 262, 268, 28 N.E.3d 437 (2015), cert. denied, --- U.S. ----, 136 S.Ct. 1158, 194 L.Ed.2d 187 (2016), quoting Commonwealth v. LaChance, 469 Mass. 854, 857, 17 N.E.3d 1101 (2014), cert. denied, --- U.S. ----, 136 S.Ct. 317, 193 L.Ed.2d 227 (2015). See Weaver, supra ("in the case of a structural error where there is an objection at trial and the issue is raised on direct appeal, the defendant generally is entitled to 'automatic reversal' regardless of the error's actual 'effect on the outcome' " [emphasis added; citation omitted] ).

Notwithstanding the importance of the right to a public trial, it, "like other structural rights, can be waived" (citation omitted). Cohen (No. 1), 456 Mass. at 105-106, 921 N.E.2d 906. "Where counsel fails to lodge a timely objection to the closure of the court room, the defendant's claim of error is deemed to be procedurally waived." LaChance, 469 Mass. at 857, 17 N.E.3d 1101. See Commonwealth v. Alebord, 467 Mass. 106, 112, 4 N.E.3d 248, cert. denied, --- U.S. ----, 134 S.Ct. 2830, 189 L.Ed.2d 793 (2014). A claim is procedurally waived regardless of whether counsel's failure to object to the closure was a tactical decision or "where the failure to object is inadvertent." Commonwealth v. Lang, 473 Mass. 1, 9, 38 N.E.3d 262 (2015), quoting Wall, 469 Mass. at 672, 15 N.E.3d 708. See Commonwealth v. Morganti, 467 Mass. 96, 102, 4 N.E.3d 241, cert. denied, --- U.S. ----, 135 S.Ct. 356, 190 L.Ed.2d 251 (2014) (inadvertent procedural waiver where no tactical reason for counsel's failure to object). See also Commonwealth v. Vargas, 475 Mass. 338, 357, 57 N.E.3d 920 (2016) ("Such waiver need not be consented to by the defendant"). Indeed, a claim is procedurally waived "whenever a litigant fails to make a timely objection," including where counsel was unaware of the court room closure. Jackson, 471 Mass. at 269, 28 N.E.3d 437, quoting Wall, supra.

In reviewing a defendant's claim that the court room was improperly closed, the threshold inquiry is whether that claim was properly preserved at the time of the alleged closure. This court recently observed that in Weaver, 137 S.Ct. at 1910-1912, "the United States Supreme Court distinguished sharply between preserved and unpreserved errors on appeal." Commonwealth v. Kolenovic, 478 Mass. 189, 203, 84 N.E.3d 781 (2017). Reaffirming the principle that a contemporaneous objection to an offending court room closure is required to preserve the claim, we held that the dispositive inquiry is "not whether the claim was made in the direct appeal or in the motion for new trial, but rather whether the court room closure issue was preserved at trial" (emphasis **151added). Id. at 203 n.13, 84 N.E.3d 781. A contemporaneous objection is indispensable for purposes of preserving the claimed error on appeal because when the alleged error is raised contemporaneously with the closure, "the trial court can either order the court room opened or explain the reasons for keeping it closed." Weaver, supra at 1912.

Furthermore, a contemporaneous objection to an improper court room closure also creates a record that can be directly *362reviewed by an appellate court without the need for collateral proceedings to develop the court room closure issue. See Weaver, 137 S.Ct. at 1912 (when appellate courts adjudicate preserved errors raised on direct appeal, "the systemic costs of remedying the error are diminished to some extent ... because, if a new trial is ordered on direct review, there may be a reasonable chance that not too much time will have elapsed for witness memories still to be accurate and physical evidence not to be lost"). Absent a contemporaneous objection to the court room closure at trial, concluding that a claim is preserved "would tear the fabric of our well-established waiver jurisprudence ... and would defeat the core purposes of the waiver doctrine: to protect society's interest in the finality of its judicial decisions, and to promote judicial efficiency." LaChance, 469 Mass. at 858, 17 N.E.3d 1101, quoting Morganti, 467 Mass. at 102, 4" url="https://cite.case.law/citations/?q=4%20N.E.3d%20241">4 N.E.3d 241. See Commonwealth v. Randolph, 438 Mass. 290, 294, 780 N.E.2d 58 (2002). Our waiver doctrine prevents claims that are raised for the first time in postconviction proceedings from "function[ing] as a way to escape rules of waiver and forfeiture and raise issues not presented at trial, thus undermining the finality of jury verdicts" (quotation and citation omitted). Weaver, supra.

The principles underpinning the doctrine of procedural waiver are deeply ingrained in our jurisprudence, and were recently reaffirmed by the United States Supreme Court in Weaver, 137 S.Ct. at 1912. As stated, analyzing whether a claimed error was properly preserved depends on whether the defendant contemporaneously objected to the closure at trial. See Jackson, 471 Mass. at 268-269, 28 N.E.3d 437. Indeed, only where a defendant raises a contemporaneous objection to an improper court room closure at trial has this court held that the defendant's claimed Sixth Amendment public trial violation was preserved. See Cohen (No. 1), 456 Mass. at 118, 921 N.E.2d 906. In that case, the defendant objected to the court room closure when defense counsel first discovered that the court officers had placed a sign on the court room door stating, "Jury empanelment Do not enter." Id. at 98, 921 N.E.2d 906. We concluded that the **152defendant properly preserved the public trial error because he objected "at a time when the violation could have been remedied by beginning the empanelment process anew." Id. at 118 n.35, 921 N.E.2d 906, citing Commonwealth v. McDuffee, 379 Mass. 353, 359, 398 N.E.2d 463 (1979) (noting that "rationale behind the requirement of a specific exception is to enable the judge to make any necessary correction"). See Commonwealth v. Lavoie, 464 Mass. 83, 89 n.11, 981 N.E.2d 192, cert. denied, 569 U.S. 981, 133 S.Ct. 2356, 185 L.Ed.2d 1080 (2013) (noting that defendant's claim was factually different from claim in Cohen (No. 1)"in at least one important respect: Cohen's defense counsel objected to the court room closure at his trial").

Conversely, where a defendant fails to contemporaneously object to an improper court room closure at trial, we have steadfastly held that the defendant's claim is procedurally waived. See, e.g., Lang, 473 Mass. at 7-9, 38 N.E.3d 262 (no objection at trial; claim raised in first motion for new trial as Sixth Amendment violation while direct appeal pending); Jackson, 471 Mass. at 268-269, 28 N.E.3d 437 (no objection at trial; claim raised as Sixth Amendment violation in motion for new trial); Alebord, 467 Mass. at 107-108, 4 N.E.3d 248 (no objection at trial; claim not raised in first motion for new trial or direct appeal and asserted as claim of ineffective assistance of counsel); Lavoie, 464 Mass. at 84, 981 N.E.2d 192 (no objection at trial; claim raised as Sixth Amendment violation *363in defendant's first motion for new trial). Absent a contemporaneous objection, it is immaterial when or in what form the defendant later raises the claim in postconviction proceedings. See Kolenovic, 478 Mass. at 203 n.13, 84 N.E.3d 781 ("the important distinction is ... whether the court room closure issue was preserved at trial"). Cases noting that a defendant also failed to raise the claim in his or her first motion for a new trial or on direct appeal only serve to emphasize the egregiousness of the defendant's delay in raising the claim -- like here, where the defendant first raised the issue approximately thirteen years after his convictions. See, e.g., Commonwealth v. Celester, 473 Mass. 553, 577-578, 45 N.E.3d 539 (2016) (no objection at trial, and issue raised in second motion for new trial); Jackson, 471 Mass. at 268-269, 28 N.E.3d 437 (no objection at trial, and "issue also was not raised in his first motion for a new trial that preceded sentencing"); Wall, 469 Mass. at 672, 15 N.E.3d 708 (no objection at trial, "[n]or was it raised in the defendant's first motion for a new trial").

We now turn to the nucleus of the defendant's argument, that despite his counsel's failure to contemporaneously object to the improperly closed court room, his claim was not procedurally **153waived because the defendant and his counsel were factually unaware of the closure when it occurred at trial. We have considered and rejected substantially similar arguments on a number of occasions. See Jackson, 471 Mass. at 269, 28 N.E.3d 437 ; Commonwealth v. Fritz, 472 Mass. 341, 346, 34 N.E.3d 705 (2015) ; Wall, 469 Mass. at 672-673 & n.24, 15 N.E.3d 708. For the reasons underpinning our doctrine of procedural waiver discussed supra, we have held that a defendant procedurally waives a court room closure claim by failing to contemporaneously object to the closure, regardless of whether the defendant or counsel was factually aware that the court room was closed. See Jackson, supra ; Fritz, supra ; Wall, supra. In Jackson, supra, where the defendant and his counsel were unaware that the court room had been closed, this court specifically rejected the argument that the defendant's claim "cannot be procedurally waived when neither counsel nor the defendant knew of the occasion for objection." We concluded that the defendant's attempt to shield his claim from the doctrine of procedural waiver was at odds with our decision in Wall, supra, because the "right to a public trial may be procedurally waived whenever a litigant fails to make a timely objection," regardless of whether counsel or the defendant perceived the court room closure when it occurred. Jackson, supra, quoting Wall, supra at 672, 15 N.E.3d 708. This rationale applies with equal force where counsel was unaware of the occasion for objection because he or she did not realize that the defendant's Sixth Amendment right to a public trial extended to jury empanelment. See Fritz, supra.

The defendant attempts to distinguish his case from Jackson, 471 Mass. at 269, 28 N.E.3d 437, and Wall, 469 Mass. at 672-673 & n.24, 15 N.E.3d 708, because he raised the court room closure claim in his first motion for a new trial while his direct appeal was pending. Yet, as we previously emphasized, "the important distinction is not whether the claim was made in the direct appeal or in the motion for new trial, but rather whether the court room closure issue was preserved at trial." Kolenovic, 478 Mass. at 203 n.13, 84 N.E.3d 781. Furthermore, our determination that the defendant in Jackson, supra at 265-266, 269, 28 N.E.3d 437, procedurally waived his claim was predicated on his failure to timely object at trial, not because he first moved for a mistrial and motion for a new trial prior to sentencing without raising *364the **154closed court room issue,7 and then subsequently raised the issue in his first motion for a new trial postsentencing. The defendant in Jackson, like the defendant in this case, was apparently unaware of the court room closure prior to filing his first postsentencing motion for a new trial. Id. at 268-269, 28 N.E.3d 437. In both cases, the dispositive inquiry is whether the defendant objected to the closure at trial, and not a hypertechnical analysis of the precise procedural posture in which the claim is first raised posttrial. See id.

For purposes of determining whether the defendant's claim was properly preserved at trial, it is also legally irrelevant that he now presents the claim as a Sixth Amendment violation rather than a claim that his counsel provided ineffective assistance by failing to perceive and object to the closure. Regardless of the reason for counsel's failure to lodge a contemporaneous objection to the closure, the trial judge is deprived of the opportunity to evaluate the claim "at a time when the violation could have been remedied." See Cohen (No. 1), 456 Mass. at 118 n.35, 921 N.E.2d 906. Accordingly, we conclude that the defendant's failure to contemporaneously object to the court room closure constituted a procedural waiver of his claim.

Where a procedurally waived Sixth Amendment public trial claim is raised in a motion for a new trial, a reviewing court analyzes the claimed error to determine whether the error, if any, created a "substantial risk of a miscarriage of justice." LaChance, 469 Mass. at 857, 107" url="https://cite.case.law/citations/?q=17%20N.E.3d%201101">17 N.E.3d 1101. See Commonwealth v. Hill, 432 Mass. 704, 710 n.14, 739 N.E.2d 670 (2000).8 The substantial risk of a miscarriage of justice **155standard applies even where the defendant, in a capital case, files a postconviction motion for a new trial while the defendant's direct appeal is pending in this court. See Hill, supra. Only where the motion for a new trial is denied, and that denial is consolidated with the defendant's direct appeal, does this court review the totality of the defendant's case *365to determine whether there is a "substantial likelihood of a miscarriage of justice" under G. L. c. 278, § 33E. See Celester, 473 Mass. at 560, 45 N.E.3d 539 ; Jackson, 471 Mass. at 269, 28 N.E.3d 437. Accordingly, we reverse the grant of the defendant's motion for a new trial and remand the case to the Superior Court for the motion judge to determine whether the improper court room closure created a substantial risk of a miscarriage of justice.

So ordered.

I agree that the defendant has procedurally waived, or inadvertently forfeited, his court room closure claim. However, a criminal defendant should not be considered to have automatically forfeited such a claim by failing to object contemporaneously to the closure when neither he nor his defense counsel (nor the judge) knew or had reason to know of it.1 In my view, this question is primarily governed by principles expressed in the Massachusetts Rules of Criminal Procedure, and I would conclude instead that the defendant forfeited his court room closure claim because we presume that he had the opportunity **156to discover this claim and bring it to a court's attention in a more timely fashion with the exercise of reasonable diligence.

1. Massachusetts Rules of Criminal Procedure and procedural waiver. Under Mass. R. Crim. P. 22, 378 Mass. 892 (1979), and Mass R. Crim. P. 30, as appearing in 435 Mass. 1501 (2001), there are at least two ways that a claim can be procedurally waived. First, rule 22 generally requires objections at trial in order to preserve claims of error. If a claim is not objected to at trial, it is waived. See Mass. R. Crim. P. 22. However, the rule also states in pertinent part:

"if a party has no opportunity to object to a ruling or order, the absence of an objection does not thereafter prejudice him."

Id.

Additionally, a defendant may procedurally waive a preserved claim of error posttrial if he or she fails to raise it in his or her first motion for a new trial. Rule 30 (b) permits a "trial judge upon motion" to "grant a new trial at any time if it appears justice may not have been done." However, the rule also calls for the waiver of any claims that may be brought under rule 30 but are not raised in the defendant's first motion for a new trial:

"All grounds for relief claimed by defendant under [provisions of rule 30 ] shall be raised by the defendant in the original or amended motion. Any grounds not so raised are waived unless the judge in the exercise of discretion permits them to be raised in a subsequent motion, or unless such grounds could not reasonably have been raised in the original or amended motion."

Mass. R. Crim. P. 30 (c) (2).

These rules are consistent with the principle that a "right may be forfeited in criminal as well as civil cases by the failure to make a timely assertion of the right before a tribunal having jurisdiction to determine it."

*366Puckett v. United States, 556 U.S. 129, 134, 129 S.Ct. 1423, 173 L.Ed.2d 266 (2009), quoting Yakus v. United States, 321 U.S. 414, 444, 64 S.Ct. 660, 88 L.Ed. 834 (1944).

2. Procedural waiver in court room closure cases. In cases in which defense counsel had an opportunity to object at trial because he or she knew or had reason to know of the court room closure and failed to object, we have concluded, consistently with rule 22, that the defendant's public trial right was waived because the claim was not timely preserved (i.e., at trial). See **157Commonwealth v. Kolenovic, 478 Mass. 189, 203 n.14, 84 N.E.3d 781 (2017) ;2 Commonwealth v. Vargas, 475 Mass. 338, 357, 57 N.E.3d 920 (2016) ; Commonwealth v. Lang, 473 Mass. 1, 9, 38 N.E.3d 262 (2015) ; Commonwealth v. Fritz, 472 Mass. 341, 346, 34 N.E.3d 705 (2015) ; Commonwealth v. LaChance, 469 Mass. 854, 855-856, 17 N.E.3d 1101 (2014), cert. denied, --- U.S. ----, 136 S.Ct. 317, 193 L.Ed.2d 227 (2015) ; Commonwealth v. Alebord, 467 Mass. 106, 108, 4 N.E.3d 248, cert. denied, --- U.S. ----, 134 S.Ct. 2830, 189 L.Ed.2d 793 (2014) ; Commonwealth v. Morganti, 467 Mass. 96, 102, 4 N.E.3d 241, cert. denied, --- U.S. ----, 135 S.Ct. 356, 190 L.Ed.2d 251 (2014) ; Commonwealth v. Lavoie, 464 Mass. 83, 87-89, 981 N.E.2d 192, cert. denied, 569 U.S. 981, 133 S.Ct. 2356, 185 L.Ed.2d 1080 (2013). See also Weaver v. Massachusetts, --- U.S. ----, 137 S.Ct. 1899, 1906, 198 L.Ed.2d 420 (2017) ;3 Levine v. United States, 362 U.S. 610, 619, 80 S.Ct. 1038, 4 L.Ed.2d 989 (1960) (court room closure claim waived where "[c]ounsel was present throughout, and it is not claimed that he was not fully aware of the exclusion of the general public").4 In each case, we held the claim to be untimely, regardless of whether it was presented in a motion for a new trial or in a direct appeal, because the defendant had been aware of the closure and had failed to object to it at the time of the closure. See Mass. R. Crim. P. 22.

However, the question whether a claim was preserved at trial cannot fairly be asked in a situation in which a defendant did not have an opportunity to object contemporaneously with the closure. See ibr.US_Case_Law.Schema.Case_Body:v1">id. We have considered at least two public trial cases **158where the defendant first raised a public trial right claim after the trial had *367concluded and defense counsel was unaware of the closure at the time of trial.5 See Commonwealth v. Jackson, 471 Mass. 262, 269, 28 N.E.3d 437 (2015), cert. denied, --- U.S. ----, 136 S.Ct. 1158, 194 L.Ed.2d 187 (2016) ; Commonwealth v. Wall, 469 Mass. 652, 672-673, 15 N.E.3d 708 (2014). In both cases, we looked to indications of timeliness based on the circumstances presented in each case. For example, in Wall, the defendant's claim was untimely not merely because he did not raise it at trial (when he was unaware of the exclusion), but because he also failed to raise the claim until his second motion for a new trial, filed "almost four years after he filed his first ... and over seven years after his conviction." Wall, supra at 672, 15 N.E.3d 708. Importantly, we did not say that the objection needed to be contemporaneous with the error.

In Jackson, 471 Mass. at 269, 28 N.E.3d 437, relying on Wall, we concluded that although neither the defendant nor his counsel knew of the court room closure at the time of trial, the defendant's public trial claim was untimely where he did not raise the issue until four years after his convictions in a second motion for a new trial. Here again, we did not hold that the objection had to be contemporaneous in order to be timely where the defendant had no actual or constructive knowledge of the closure. See ibr.US_Case_Law.Schema.Case_Body:v1">id. See also Commonwealth v. Celester, 473 Mass. 553, 560, 578, 45 N.E.3d 539 (2016) (claim procedurally waived when defendant first raised public trial claim eighteen years after trial).

It is true that, thus far, we have not deemed timely a closed court room claim brought posttrial where the defendant was unaware of the error at trial. However, we so concluded only after a review of the circumstances in each case. See Jackson, 471 Mass. at 269, 28 N.E.3d 437 ; Wall, 469 Mass. at 673, 15 N.E.3d 708. Rather than holding that the defendants' claims were untimely because they failed to make a contemporaneous objection at trial, we concluded that, on the facts presented, the claims were waived because the defendant in each case waited so long between the violation of his public trial right and bringing the claim to the attention of a court that it would be unreasonable to believe that he could not have discovered the violation earlier with the exercise of due diligence. See Reporters' Notes to Rule 30 (c) (2), Mass. Ann. Laws Court Rules, Rules of Criminal Procedure, at 1775 (LexisNexis 2016)

**159(rule of waiver "not intended to foreclose from future consideration grounds which were not known and could not have been found out with the exercise of due diligence" [emphasis added] ). Cf. Commonwealth v. Grace, 397 Mass. 303, 308-309, 491 N.E.2d 246 (1986) (question is "whether the defendant met his burden of showing that reasonable diligence would not have produced" testimony of allegedly newly discovered witnesses at earlier time).

Today, the court takes the holdings of Wall and Jackson a significant step further and, for the first time, equates a timely objection6 with a contemporaneous one, "including where counsel was unaware of *368the court room closure." Ante at ----, 102 N.E.3d at 361. This goes further than I believe is necessary or prudent, see, e.g., SCVNGR, Inc. v. Punchh, Inc., 478 Mass. 324, 330, 85 N.E.3d 50 (2017) ("it is canonical that courts should, where possible, avoid unnecessary constitutional decisions"), and is inconsistent with rule 22. The rules of a court have the force of law and are as binding on a court as are statutes. Commonwealth v. Brown, 395 Mass. 604, 606, 481 N.E.2d 469 (1985) ("Requiring courts to abide by their own rules is supported by the fundamental principle of justice that the law must treat persons similarly situated uniformly").

3. Due process concerns. In addition, I believe that the court's ruling is inconsistent with minimum standards of due process. "For more than a century the central meaning of procedural due process has been clear: 'Parties whose rights are to be affected are entitled to be heard; and in order that they may enjoy that right they must first be notified.' " Fuentes v. Shevin, 407 U.S. 67, 80, 92 S.Ct. 1983, 32 L.Ed.2d 556 (1972), quoting Baldwin v. Hale, 1 Wall. 223, 233, 68 U.S. 223, 17 L.Ed. 531 (1863).

The court focuses on the fact that where, as here, a court officer acted alone and without notice to the judge or the parties, the judge is at a disadvantage because he or she did not have an opportunity to correct the error at the time it occurred. However, the more troubling issue is that a defendant, who has no opportunity to bring the closure to the court's attention, suffers the consequences of the error. Today's ruling has the effect of barring defendants from asserting their constitutional rights in a timely way through no fault of their own.7

**1604. The instant case. In this case, the defendant waited nearly fourteen years between the initial trial and bringing the court room closure to the attention of a court. Although the motion judge found that neither he nor his counsel had notice of the closure at the time of trial, we must presume that the defendant had the opportunity to discover this claim and bring it to a court's attention in a more timely fashion with the exercise of reasonable diligence. Even considering the lack of knowledge of the court room closure at the time of trial, I do not consider a nearly fourteen-year span a "timely assertion of the right." Puckett, 556 U.S. at 134, 129 S.Ct. 1423, quoting Yakus, 321 U.S. at 444, 64 S.Ct. 660. See Jackson, 471 Mass. at 269, 28 N.E.3d 437, quoting Wall, 469 Mass. at 672, 15 N.E.3d 708 (requiring "timely objection" to error).

Therefore, I would conclude that the defendant has forfeited his public jury trial claim, but would leave for another day what might constitute a timely objection.8
