¶26 A defendant has a constitutional right to be present at every stage of trial when his presence has a reasonably substantial relation to the right to defend himself. E.g., Kentucky v. Stincer, 482 U.S. 730, 745, 107 S.Ct. 2658, 2667, 96 L.Ed.2d 631 (1987); Levato, 186 Ariz. at 443, 924 P.2d at 447; see State v. McCrimmon, 187 Ariz. 169, 171, 927 P.2d 1298, 1300 (1996). As we said above, it is sound procedure that the defendant’s presence not be waived in the absence of consultation with counsel when issues of substance are before the trial court and particularly if the jury is to be present. See Levato, 186 Ariz. at 443, 924 P.2d at 447. The right, however, to be present in this situation is hot of such nature that it cannot be waived by counsel.
¶ 27 In State v. Collins, 133 Ariz. 20, 23, 648 P.2d 135, 138 (App.1982), this court held that defense counsel could waive a defendant’s right to be present at the exercise of peremptory strikes of prospective jurors, and that the trial court could accept such a waiver without obtaining a personal declaration from the defendant. Criminal defendants have been bound by counsel’s waiver of other rights as well. E.g., Levato, 186 Ariz. at 444, 924 P.2d at 448. In this case, the “additional instructions” consisted merely of a reiteration of instructions relating to the jurors’ obligations to give the case careful consideration and to participate fully in deliberations. We reject the defendant’s contention that his presence at such “remstruction” was more critical than his presence at the return of a verdict or the polling of jurors. See id. at 445, 924 P.2d at 449. The defendant was bound by counsel’s waiver.
3. Gang-enhancement Allegation
¶ 28 The defendant contends that the trial court erred in allowing the prosecutor to allege gang motivation for the purpose of sentence enhancement after trial had begun. He claims that, had the prosecutor given notice of his intent to seek enhancement before the jury was chosen, he would have employed a different strategy during jury selection and exercised his peremptory strikes differently.
¶ 29 Various subsections of A.R.S. section 13-604 afford sentence enhancement when certain aggravating circumstances have been alleged and proven. Subsection T provides that, if an offense was committed with the intent to promote, further or assist criminal conduct by a criminal street gang, the prison term for the offense “shall be increased by three years.”
¶ 30 Section 13-604(P) sets forth time limitations for the filing of other allegations under section 13-604, but it contains no mention of allegations of gang motivation. Whatever the reason for the exclusion, though, and although the trial court concluded that the allegation was timely under section 13-604(P), we need not decide whether section 13-604(P) applies because the prosecutor’s request to amend the indictment, filed more than one week after the trial had begun, was untimely under Rule 16.1(b).
¶ 31 Rule 16.1(b) requires that motions be made no later than 20 days prior to trial, defined as the date the case is actually tried. Committee Comment to 1993 Amendments to Rule 16. Rule 16.1(c) provides that untimely motions or requests “shall” be precluded, unless the basis for the request was not known and, by the exercise of reasonable diligence, could not have been known.
¶ 32 The prosecutor did not file the request to amend the indictment to include the sentence-enhancement allegation until nine days after the jury was impaneled. In analyzing the words “actually tried” as used in A.R.S. section 13-604(P), the trial court interpreted the rule to mean “up until the return of a verdict,”6 but the requirement that sentence-enhancement allegations be filed prior to trial is intended to ensure that a defendant has sufficient notice of the full extent of potential punishment before his trial begins. State v. Rodgers, 134 Ariz. 296, 306-07, 655 P.2d 1348, 1358-59 (App.1982). Fundamental fairness thus requires that a

This ruling was made despite the fact that section 13-604(P) allows enhancement allegations to be made at any time but prior to the date the case is actually tried, unless the allegation is filed fewer than 20 days before the case is tried and the court finds on the record that the defendant suffered prejudice due to the late filing.
