In this case we determine whether an incriminating statement made by a juvenile during a custodial interrogation must be suppressed at trial, pursuant to N.C.G.S. § 7B-2101, when the juvenile had requested to telephone his aunt before making the statement. We hold that the statement need not be suppressed since defendant’s aunt was not a “guardian” for purposes of the relevant statute. Accordingly, we affirm the decision of the Court of Appeals in part. We also vacate and remand the decision of the Court of Appeals in part for further proceedings.
BACKGROUND
On 7 July 2003, the Forsyth County Grand Jury returned a true bill of indictment charging defendant with first-degree murder, first-degree kidnapping, and attempted robbery with a firearm in connection with the fatal shooting of Scott Gray Jester during the early morning hours of 10 September 2002. Jester’s body had been discovered later the same morning near an exit ramp off Interstate 40 in Winston-Salem after he had sustained three gunshot wounds to the back of the head. On 3 November 2003, the Forsyth County Grand Jury also returned a true bill of indictment charging defendant with two counts of robbery with a dangerous weapon in connection with the robberies of two convenience stores on 7 September 2002 and on 8 September 2002. On 24 May 2004, defendant entered a plea of guilty to the two charges of robbery with a dangerous weapon, but the trial court postponed sentencing on those convictions until after defendant’s trial on the three remaining charges.
Also on 24 May 2004, and before defendant’s trial, the trial court heard defendant’s motion to suppress an incriminating statement he made to law enforcement officers with the Winston-Salem Police Department during a custodial interrogation which had taken place on 11 September 2002, when defendant was .sixteen years old. Defendant’s contention was that his juvenile rights were violated during the interrogation because the detectives did not cease questioning him when he requested to telephone his aunt and that therefore the statement should be suppressed. At the conclusion of the pretrial *553hearing, the trial court made findings of fact that defendant’s aunt was not his guardian or custodian under N.C.G.S. § 7B-2101 and that, although defendant requested to telephone his aunt, this “was not a time specific request,” nor did defendant say he would not speak with the officers until he was allowed to place the call. Based upon these findings, the trial court concluded that there was no statutory or constitutional violation of defendant’s juvenile rights and denied defendant’s motion to suppress.
On 28 May 2004, the jury found defendant guilty of first-degree murder under the felony murder rule, first-degree kidnapping, and attempted robbery with a firearm. The trial court entered judgment consistent with the jury’s verdict, and defendant was sentenced to life imprisonment without parole for the felony murder conviction and in the presumptive ranges for the first-degree kidnapping and attempted robbery convictions. Also on 28 May 2004, the trial court entered judgment on the two charges of robbery with a dangerous weapon consistent with defendant’s plea of guilty. The trial court sentenced defendant in the aggravated range for both convictions, finding the same aggravating factor for both: That defendant joined with more than one other person in the commission of the offense and was not charged with committing a conspiracy.
Defendant appealed to the Court of Appeals, which in a unanimous 6 December 2005 opinion found no error in part and remanded the case in part for resentencing. The State and defendant petitioned this Court for discretionary review of the Court of Appeals decision, and these petitions were subsequently allowed on 19 December 2006. The State has raised one issue before the Court on appeal: Whether the trial court committed reversible Blakely error by sentencing defendant in the aggravated range for his two convictions for robbery with a dangerous weapon. Defendant has raised three issues: (1) whether the trial court erred in denying his motion to suppress; (2) whether the trial court erred in ordering that defendant be restrained by leg shackles; and (3) whether defendant’s conviction for murder should be vacated because the indictment did not set forth all the elements of first-degree murder.
ANALYSIS
[1] We determine first whether the trial court erred in denying defendant’s motion in limine to suppress the statement he made to law enforcement officers on 11 September 2002. The State contends that defendant should be barred from raising this issue on appeal *554since he did not renew his objection at trial and has not argued, alternatively, that the trial court committed plain error by allowing the statement entered into evidence. See N.C. R. App. P. 10(c)(4); State v. Golphin, 352 N.C. 364, 449, 533 S.E.2d 168, 224 (2000), cert. denied, 532 U.S. 931 (2001).
As the Court of Appeals indicated, defendant may have relied to his detriment on a 2003 amendment to the North Carolina Rules of Evidence, which provides in pertinent part: “Once the [trial] court makes a definitive ruling on the record admitting or excluding evidence, either at or before trial, a party need not renew an objection or offer of proof to preserve a claim of error for appeal.” N.C.G.S. § 8C-1, Rule 103(a)(2) (2005) (emphasis added). There is a direct conflict between this evidentiary rulé and North Carolina Rule of Appellate Procedure 10(b)(1), which this Court has consistently interpreted to provide that a trial court’s evidentiary ruling on a pretrial motion is not sufficient to preserve the issue of admissibility for appeal unless a defendant renews the objection during trial. See State v. Roache, 358 N.C. 243, 292, 595 S.E.2d 381, 413 (2004); State v. Grooms, 353 N.C. 50, 65-66, 540 S.E.2d 713, 723 (2000), cert. denied, 534 U.S. 838 (2001); Golphin, 352 N.C. at 449, 533 S.E.2d at 224; State v. Hayes, 350 N.C. 79, 80, 511 S.E.2d 302, 303 (1999) (per curiam); State v. Bonnett, 348 N.C. 417, 437, 502 S.E.2d 563, 576-77 (1998), cert. denied, 525 U.S. 1124 (1999). For this reason, our intermediate appellate court has already held that Rule of Evidence 103(a)(2) is unconstitutional to the extent it conflicts with Rule of Appellate Procedure 10(b)(1). See State v. Tutt, 171 N.C. App. 518, 524, 615 S.E.2d 688, 692-93 (2005).
The Constitution of North Carolina expressly vests in this Court the “exclusive authority to make rules of procedure and practice for the Appellate Division.” N.C. Const. art. IV, § 13, cl. 2. Although Rule 103(a)(2) is contained in the Rules of Evidence, it is manifestly an attempt to govern the procedure and practice of the Appellate Division as it purports to determine which issues are preserved for appellate review. Accordingly, we hold that, to the extent it conflicts with Rule of Appellate Procedure 10(b)(1), Rule of Evidence 103(a)(2) must fail. See State v. Stocks, 319 N.C. 437, 439, 355 S.E.2d 492, 493 (1987); State v. Bennett, 308 N.C. 530, 535, 302 S.E.2d 786, 790 (1983); State v. Elam, 302 N.C. 157, 160, 273 S.E.2d 661, 664 (1981).
As a consequence of the invalidity of Rule 103(a)(2) and the application of Appellate Rule 10(b)(1) to the instant case, defendant *555has failed to preserve the admissibility of his incriminating statement for appellate review. Nor has defendant argued that the trial court committed plain error. See N.C. R. App. P. 10(c)(4); Golphin, 352 N.C. at 449, 533 S.E.2d at 224. Nevertheless, as the Court of Appeals noted, the amendment to Rule 103(a)(2) was presumed constitutional at the time of defendant’s trial, which was held before the Court of Appeals decision in Tutt. Given the harsh consequences of barring review when a defendant has relied to his detriment on existing law, we exercise this Court’s discretion under Appellate Procedure Rule 2 “to prevent manifest injustice” to defendant and to review his contention on the merits. See N.C. R. App. P. 2; see also Stocks, 319 N.C. at 439, 355 S.E.2d at 493; Elam, 302 N.C. at 161, 273 S.E.2d at 664.
[2] An accused juvenile’s rights during a custodial interrogation are codified in N.C.G.S. § 7B-2101, which states in part that “[a]ny juvenile in custody must be advised prior to questioning . . . [t]hat the juvenile has a right to have a parent, guardian, or custodian present during questioning.” N.C.G.S. § 7B-2101(a)(3) (2005).1 The statute further provides that “[i]f the juvenile indicates in any manner and at any stage of questioning . . . that the juvenile does not wish to be questioned further, the officer shall cease questioning.” Id. § 7B-2101(c) (2005). Before allowing evidence to be admitted from a juvenile’s custodial interrogation, a trial court is required to “find that the juvenile knowingly, willingly, and understandingly waived the juvenile’s rights.” Id. § 7B-2101(d) (2005). Defendant argues that the interrogation should have ceased when he requested to telephone his aunt, whom he asserts was effectively a “guardian,” and that therefore the trial court erred under N.C.G.S. § 7B-2101(d) by denying his motion to suppress the incriminating statement he made shortly after his request was denied by the interrogating officers.
Clearly, defendant was entitled by N.C.G.S. § 7B-2101(a)(3) to have a “parent, guardian, or custodian” present during his interrogation. However, an “aunt” is not an enumerated relation in the statute, and an interpretation of the term “guardian” to encompass anything other than a relationship established by legal process would unjustifiably expand the plain and unambiguous meaning of the word. See Black’s Law Dictionary 566 (abr. 7th ed. 2000) (defining “guardian” *556as “[o]ne who has the legal authority and duty to care for another’s person or property” (emphasis added)). We are bound by well-accepted rules of statutory construction to give effect to this plain and unambiguous meaning and we therefore decline any attempt to ascertain a contrary legislative intent. See, e.g., In re A.R.G., 361 N.C. 392, 396, 646 S.E.2d 349, 351 (2007).
The trial court made a finding of fact that defendant’s aunt was not his guardian or custodian. From the testimony of defendant’s aunt, it is apparent that she never had custody of defendant, that defendant had only stayed with her on occasion but not for any considerable length of time, and that she had never signed any school papers for him. As the trial court’s finding of fact is supported by competent evidence, it cannot be disturbed on appeal. See State v. Ripley, 360 N.C. 333, 339, 626 S.E.2d 289, 293 (2006). Moreover, the only evidence which could possibly support a contrary finding of fact is the aunt’s testimony that she was “a mother figure” to defendant. However, this does not amount to the legal authority inherent in a guardian or custodial relationship. Defendant’s aunt was clearly not a statutory person, and defendant therefore had no right to have her present during questioning. Thus, we affirm in part the decision of the Court of Appeals.
[3] However, we vacate the portion of the Court of Appeals decision in which that court found Blakely error in defendant’s aggravated sentences for robbery with a dangerous weapon, which it treated as structural error, and remand to the Court of Appeals for harmless error review pursuant to State v. Blackwell, 361 N.C. 41, 42, 49-51, 638 S.E.2d 452, 453, 458-59 (2006), cert. denied, -U.S. -, 127 S. Ct. 2281, 167 L. Ed. 2d 1114 (2007). As to the additional issues presented in defendant’s petition, we conclude that discretionary review was improvidently allowed.
AFFIRMED IN PART; VACATED AND REMANDED IN PART; DISCRETIONARY REVIEW IMPROVIDENTLY ALLOWED IN PART.
