delivered the Opinion of the Court.
¶1 A jury convicted Errol Mann (Mann) of burglary and two counts of misdemeanor assault following a two-day trial in the Eighth Judicial District Court, Cascade County. He asserts on appeal that the District Court violated bis fundamental constitutional right to be present and appear at all criminal proceedings. Mann also alleges ineffective assistance of counsel based on the jury instructions his appointed counsel, John Keith (Keith) offered.
¶2 We rephrase the issues on appeal as follows:
¶3 1. Whether the District Court violated Mann’s constitutional right to appear at all criminal proceedings against him when the court excluded him from a pre-trial meeting that addressed Mann’s allegations of ineffective assistance of counsel, Mann’s request to represent himself, and Keith’s perceptions of bis client.
¶4 2. Whether Keith’s decision to request jury instructions for the lesser included offenses charged deprived Mann of the right to effective assistance of counsel.
STATEMENT OF FACTS AND PROCEDURAL HISTORY
¶5 Police arrested Mann following an incident at a private residence in Great Falls. Mann remained in a house where he had formerly lived, despite being asked to leave repeatedly. The two female residents told police that Mann threatened them with a small caliber pistol while he remained in their home. The State charged Mann with aggravated burglary and two counts of assault with a weapon. Mann entered a plea of not guilty, and the case proceeded to trial.
¶6 Cascade County Public Defender Megan Lulf (Lulf) first represented Mann but later cited a conflict and withdrew. The court substituted Keith to represent Mann. Mann informed the court immediately prior to the trial’s outset, however, that he was dissatisfied with Keith’s performance. The court inquired further and determined that no grounds to substitute counsel existed. Mann then announced that he would rather represent himself than proceed with *478Keith as his attorney. The court informed Mann of the risks he would assume should he choose to represent himself. Mann insisted that he was determined to proceed without counsel. The court then excused Mann from the meeting, and continued the discussion concerning Mann’s representation with Keith and the State on the record, addressing whether the District Court would permit Mann to proceed pro se.
¶7 Although the court did not ask Keith to respond to Mann’s complaints, Keith proceeded to expound upon Mann’s attitude and his own performance as counsel. He informed the court that Mann would never listen to him and stated twice that Mann had called Keith a liar. Keith further offered that Lulf had withdrawn “because she was threatened by Mr. Mann. She was genuinely frightened of him.” Keith also described the deteriorating relationship between him and his client, and asserted on several occasions that he believed Mann would disrupt the proceedings if the court prevented Mann from representing himself. At the conclusion of this somewhat lengthy discussion, the bailiff returned Mann to the courtroom and, unaware of what transpired outside his presence, Mann changed his mind and elected to proceed with Keith as counsel. The prospective jurors entered the room and voir dire began.
¶8 Keith offered instructions on the lesser included offenses of burglary and misdemeanor assault when the parties settled jury instructions at the end of the first day of trial. The jury returned a guilty verdict the next day on these two charges. Judge Neill sentenced Mann as a persistent felony offender to thirty years at the Montana State Prison for burglary and two six-month sentences for the misdemeanor assault charges. The District Court ordered the sentences to run concurrently.
¶9 Mann appeals his sentence and conviction, asserting that he was wrongly excluded from a critical stage of the proceedings against him, and that he was deprived of his right to effective assistance of counsel.
STANDARD OF REVIEW
¶10 A district court’s determination of whether a criminal defendant’s right to be present at the critical stages of his or her trial is a question of constitutional law. State v. Aceto, 2004 MT 247, ¶ 15, 323 Mont. 24, ¶ 15, 100 P.3d 629, ¶ 15. Our review of constitutional law questions is plenary. Aceto, ¶ 15.
ISSUE ONE
¶11 Whether the District Court violated Mann’s constitutional right *479to appear at all criminal proceedings against him when the court excluded him from a pre-trial meeting that addressed Mann’s allegations of ineffective assistance of counsel, Mann’s request to represent himself, and Keith’s perceptions of his client.
¶12 The Confrontation Clause of the Sixth Amendment provides a criminal defendant the right to be present at all criminal proceedings against him. Illinois v. Allen (1970), 397 U.S. 337, 338, 90 S.Ct. 1057, 1058, 25 L.Ed.2d 353, 356. The Montana Constitution includes express language aimed at protecting this right, providing that, “[i]n all criminal prosecutions the accused shall have the right to appear and defend in person and by counsel....” Article II, Sec. 24, Mont. Const. We have established that the right to appear and defend is a fundamental right which may only be waived through an informed, intelligent, and recorded waiver. State v. Tapson, 2001 MT 292, ¶¶ 15, 28, 307 Mont. 428, ¶¶ 15, 28, 41 P.3d 305, ¶¶ 15, 28; State v. Kennedy, 2004 MT 53, ¶ 29, 320 Mont. 161, ¶ 29, 85 P.3d 1279, ¶ 29.
¶13 The 1889 Montana Constitution contained language identical to the right to appear and defend provision found today, and Montana case law has historically reflected the importance this state places on such rights. In one of its first opportunities to address the right to appear and defend clause, found at that time in Article III, Section 16, this Court stated that “the defendant must be present throughout the entire trial.” State v. Reed (1922), 65 Mont. 51, 56, 210 P. 756, 757 (emphasis added). We added further that the defendant has a legal right to be present “when the jury are hearing his case, and at all times during the proceeding of the trial, when anything is done which in any manner affects his right....” Reed, 65 Mont. at 58, 210 P. at 758 (emphasis added). We then stated over forty years later that a defendant's Article II, Section 24 rights are violated if he “is prevented from attending other proceedings where his presence is essential to a fair and just determination of a substantial issue.” State v. Schenk (1968), 151 Mont. 493, 500, 444 P.2d 861, 864.
¶14 In recent years, we have been called upon to determine whether various situations in which the accused has been excluded from trial proceedings have resulted in a violation of a defendant’s constitutional rights. For example, we concluded that the district court violated the defendant’s rights when it excluded the defendant and his counsel from an in-chambers voir dire. State v. Bird, 2001 MT 2, ¶ 40, 308 Mont. 75, ¶ 40, 43 P.3d 266, ¶ 40. We also concluded a violation occurred when the trial judge entered the jury room during deliberations, Tapson, ¶ 33, and when a judge ordered the defendant removed from the courtroom for the duration of trial without warning, *480following courtroom outbursts by the defendant. Aceto, ¶ 48.
¶15 We have not always concluded, however, that an alleged violation of this constitutional right warrants automatic reversal. Rather, we consider the effect the violation has on the defendant to determine whether the defendant suffered any conceivable prejudice. For example, in Kennedy, we concluded that the district court’s act of excluding Kennedy from a private conversation the judge shared with a juror regarding the juror’s violation of the court’s order to not communicate with trial witnesses, violated Kennedy’s right to be present at all critical stages of his trial. Kennedy, ¶ 27. We held nonetheless that the effect of Kennedy’s exclusion did not prejudice him in any way, because any opportunity Kennedy missed to question the juror about his alleged misconduct was mooted when the district court removed the juror from the panel and further prevented the witness with whom the juror had contact from testifying at trial. Kennedy, ¶ 34.
¶16 On the other hand, we determined in Bird that the violation of Bird’s constitutional right to be present warranted automatic reversal when the district court excluded him from an in-chambers voir dire. Bird, ¶ 40. We noted that the purpose of the voir dire was to elicit the prospective juror’s personal feelings and experiences regarding domestic violence. The effect of the constitutional violation deprived Bird of the opportunity to hear the juror explain her biases and thus prevented Bird “from knowing about her prejudices and from insisting that defense counsel strike her with a peremptory challenge.” Bird, ¶ 28.
¶17 Here, by the time the District Court excluded Mann from the pre-trial meeting, it had already conducted the inquiry to determine whether Mann’s allegations of ineffective assistance of counsel were substantial, State v. Gallagher, 1998 MT 70, ¶ 15, 288 Mont. 180, ¶ 15, 955 P.2d 1371, ¶ 15, and concluded that since Mann had failed to present “any concrete substantive complaint about counsel,” there was no basis to substitute counsel. This left the District Court to determine the question of whether Mann should be allowed to proceed pro se or with Keith as counsel, and it was from this discussion that Mann was excluded. The Dissent properly points out that following Mann’s exclusion, the District Court also addressed security matters and held a discussion regarding an evidentiary matter. Nonetheless, the conversation included discussions regarding the determination of whether Mann himself or Keith would provide representation in the imminent trial. As this important determination implicates a substantial issue in the scope of the criminal proceedings against him, *481we deem such exclusion a violation of Mann’s constitutional right to be present and defend himself. We now turn to the effect of the exclusion to resolve whether this constitutional violation warrants reversal. ¶18 The right to effective assistance of counsel and the right to self-representation are two of the vital rights the constitution affords criminal defendants. The Sixth Amendment of the United States Constitution and Article II, Section 24 of the Montana Constitution guarantee the right to effective assistance of counsel. State v. Lamere, 2005 MT 118, ¶ 7, 327 Mont. 115, ¶ 7, 112 P.3d 1005, ¶ 7. The same provisions provide a criminal defendant the right to proceed pro se. Faretta v. California (1975), 422 U.S. 806, 821, 95 S.Ct. 2525, 2534, 45 L.Ed.2d 562, 574; State v. Woods (1997), 283 Mont. 359, 372-73, 942 P.2d 88, 97. Mann, like any other criminal defendant, was entitled to knowingly and intelligently decide how to exercise these rights.
¶19 Here, unlike in Kennedy, Mann was not afforded a remedy following his exclusion from the pre-trial discussion that would have rendered the constitutional violation moot. Kennedy, ¶ 34. Rather, Mann was forced to make a decision regarding the substantial issue of whether to represent himself at trial or proceed with Keith as his representative without having the benefit of hearing all the pertinent information. The Dissent notes that the District Court did not make any statements “regarding Mann’s self-representation” in Mann’s absence. The crux of what Mann missed, however, was not the District Court’s comments, but those of his own attorney, from whom this Court, the Professional Rules of Conduct, the Sixth Amendment to the United States Constitution and Article II, Section 24 of the Montana Constitution demand a duty of loyalty. State v. Jones (1996), 278 Mont. 121, 125, 923 P.2d 560, 562-63; Rule 1.6, MRPC.
¶20 Mann’s absence from the discussions among the court, the State, and Keith deprived him of the opportunity to hear his own attorney, with whom Mann had already expressed deep dissatisfaction, describe for both the court and the State his personal biases against Mann and his very negative perception of his own client. Mann was unable to hear his lawyer accuse him of threatening another attorney, inform the court that Mann would never listen to him and had called him a liar, and deride Mann’s choice of a specific witness Mann wanted to call in his defense. Keith spoke further of when “the relationship [between Mann and Keith] started to go downhill” and stated that “everything seemed to unravel.” Lastly, Keith presented hearsay and speculated that Mann would misbehave and disrupt the proceedings if the court refused to allow Mann to proceed pro se. Mann’s inability to hear this protracted discussion clearly rendered his subsequent decision to *482proceed with Keith rather than pro se-an unquestionably critical decision-both unintelligent and uninformed.
¶21 We conclude that the District Court violated Mann’s constitutional right to appear at all critical stages of the proceedings against him when it excluded him from a pre-trial discussion at which Keith portrayed his client in a negative light, and whose purpose was to decide whether Mann would represent himself or proceed with Keith as counsel. This exclusion prevented Mann from exercising in a meaningful way the significant constitutional rights afforded him by the Sixth Amendment of the United States Constitution and Article II, Section 24 of the Montana Constitution-the rights to effective assistance of counsel or to choose to represent oneself at trial. See ¶ 18, above. We therefore reverse and remand for a new trial.
ISSUE TWO
¶22 Whether Keith’s decision to request jury instructions for the lesser included offenses charged deprived Mann of the right to effective assistance of counsel.
¶23 In light of our decision to reverse and remand on Issue One, we deem it unnecessary to address Issue Two.
¶24 Reversed.
JUSTICES NELSON, LEAPHART and MORRIS concur.
