Before HOEKSTRA, P.J., and WHITBECK and COOPER, JJ.
WHITBECK, J.
Defendant Walter Williams pleaded guilty of unarmed robbery.[1] We granted his delayed application for leave to appeal. We affirm.

I. Basic Facts And Procedural History
Williams' conviction arises from an incident in December 1998 in which he and three others robbed two individuals at gunpoint. Williams, who was born on October 17, 1982, was charged as a juvenile with two counts of armed robbery[2] and two counts of possessing a firearm during the commission of a felony.[3]
The prosecutor moved to waive the jurisdiction of the Family Division of the Berrien Circuit Court (hereafter the family court) pursuant to the "traditional waiver" process because sixteen-year-old Williams was at least fourteen years old and the robbery, if committed by an adult, would be a felony[4] and because Williams had been previously tried and convicted of a *82 felony in the circuit court.[5] The family court found probable cause to believe that a robbery had been committed, that it would be a felony if committed by an adult, and that Williams committed the offense. However, the family court refused to hold a second hearing at which it would determine whether Williams' best interests and the public's best interests required continuing family court jurisdiction or a trial in the court of general jurisdiction (the Criminal Division of the Berrien Circuit Court, hereafter the circuit court). Rather, because Williams had been tried for a previous offense as an adult in a circuit court, the family court simply waived jurisdiction to the circuit court. In July 1999, Williams pleaded guilty of unarmed robbery in the Berrien Circuit Court, which sentenced him as an adult to six to fifteen years' imprisonment, without determining whether an adult sentence was in his best interests or the best interests of the public.

II. Preservation And Standard Of Review
On appeal, Williams contends that the circuit court erred in not holding a sentencing hearing pursuant to MCR 6.931 to determine whether to sentence him as an adult or a juvenile. He failed to preserve this issue for appellate review by raising it in the circuit court.[6] We presume without deciding that his argument alleges a constitutional error because it implicates the process to which he was due under the court rules and state statutes. Thus, our review is for plain error affecting his substantial rights.[7]

III. Statutory and Court Rule Construction
The issue presented in this case requires that we interpret and apply a variety of statutes and court rules. The interpretative rules, which govern both the court rules and the statutes at issue,[8] are familiar. If the language is unambiguous, this Court must enforce it without any further analysis.[9] Only when "reasonable minds" could disagree regarding the proper meaning of the statute or court rule does the Court have a role in interpreting it.[10] The language "should be construed reasonably" and the Court should keep the purpose of the statute or court rule in mind.[11]

IV. Traditional Waiver Cases
The prosecutor in this case used a traditional waiver process to transfer Williams' proceedings from the family court's jurisdiction to the circuit court's jurisdiction. To effect this jurisdictional change, the traditional waiver statute[12] ordinarily requires a two-phased waiver hearing. In the first phase of the hearing, the family court must
determine on the record if there is probable cause to believe that an offense has been committed that if committed by an adult would be a felony and if there is *83 probable cause to believe that the juvenile committed the offense.[13]
The family court in this case held this probable cause hearing.
The second phase of the traditional waiver process requires the family court to determine whether the best interests of the juvenile and the best interests of the public require a trial in the court of general jurisdiction rather than in the family court.[14] Although the Legislature has prescribed six criteria the family court must consider when making this best interests determination,[15] the family court retains the discretion to make the ultimate decision whether to waive jurisdiction over the juvenile.[16] However, subsection 5 of the traditional waiver statute separately provides that the family court "shall waive jurisdiction of the juvenile if the court finds that the juvenile has previously been subject to the jurisdiction of the circuit court" as a result of criminal conduct.[17] This mandatory waiver language makes the best interests determination conducted in a phase-two hearing irrelevant to a family court's decision to waive jurisdiction over a juvenile to the circuit court. Consequently, in accordance with the statutory scheme, the family court in this case did not conduct a phase-two hearing for Williams.
Following a conviction in the circuit court, the circuit court typically must determine whether to sentence a juvenile offender as an adult or as a juvenile.[18] The best interests criteria that the trial court considers are highly similar to the criteria used to determine whether trial as an adult in a court of general jurisdiction is appropriate.[19] However, MCR 6.901(B) makes it clear that this sort of sentencing hearing leaving open the possibility of an adult or juvenile sentence does not apply in cases in which the circuit court acquires jurisdiction pursuant to a traditional waiver process. The statement in MCR 6.901(B) that "[t]he rules [in subchapter 6.900 of the court rules] do not apply to a person charged solely with an offense in which the juvenile court has waived jurisdiction pursuant to M.C.L. § 712A.4; MSA 27.3178(598.4)" could not be plainer. The interpretation that Williams advances, which would withhold a sentencing hearing under MCR 6.931 in traditional waiver cases only if the family court had conducted a phase-two hearing concerning the best interests factors, is at odds with this language in MCR 6.901(B). In this situation, our duty is clear: we must enforce the language as written[20] and hold that the circuit court did not err in failing to hold a sentencing hearing under MCR 6.931 for Williams because the family court waived jurisdiction over Williams to the circuit court under M.C.L. § 712A.4.
Michigan Supreme Court precedent supports this holding. As the Supreme Court explained in People v. Veling:[21]
*84 The postconviction sentencing hearing does not apply to jurisdiction of minors that is waived to circuit court under the traditional procedures. People v. Cosby, 189 Mich.App. 461, 473 N.W.2d 746 (1991). Moreover, the court rules detailing the hearing process do not apply to jurisdiction of minors that is waived under the traditional procedures. See MCR 6.901(B).
Rather, the juvenile sentencing hearing described in MCR 6.931 only applies to an automatic waiver case, which is not the case here.[22]

V. Thenghkam

This Court's decision in People v. Thenghkam[23] recognizes that when a traditional waiver case proceeds pursuant to M.C.L. § 712A.4(5), as in this case, a juvenile must be tried and sentenced as an adult, explaining that
under Michigan law a minor can be (1) tried and sentenced as a juvenile, (2) tried as an adult and sentenced as a juvenile, or (3) tried and sentenced as an adult. Depending on the offense charged, the automatic waiver statute and the mandatory adult sentencing provision may require this third option. Similarly, if the juvenile was previously under the jurisdiction of the recorder's court or the circuit court, this third option is mandatory.[24]
Earlier in the Thenghkam opinion, this Court made what appears to be a contradictory statement concerning a circuit court's discretion to impose a juvenile sentence, stating:
A juvenile convicted of an offense in the circuit court pursuant to this waiver provision must be sentenced in accordance with M.C.L. § 769.1(3); MSA 28.1072(3), which permits the court to impose an adult or juvenile sentence on the basis of findings relevant to explicit criteria and the way the court weighs those findings. See also MCR 6.931.[25]
We believe that the Thenghkam panel,[26] when it referred to "this waiver provision,"[27] was referring to traditional waivers as a whole class of cases and not the special subset of traditional waiver cases that encompass juveniles who have been tried previously as adults. Nevertheless, the wording in this particular portion of the Thenghkam opinion makes it difficult to distinguish between the bulk of traditional waiver cases under M.C.L. § 712A.4 that proceed pursuant to subsection 4 of that statute and the fewer cases, like this case, that fall under subsection 5 of that statute.
Clearly, the statement in Thenghkam that implies that a circuit court may impose a juvenile sentence on a minor defendant who has previously been tried as an adult is dictum, and likely erroneous dictum at that.[28] The circuit court in *85 Thenghkam did not acquire jurisdiction over the minor defendant under M.C.L. § 712A.4(5).[29] Any suggestion that certain procedures apply in traditional waiver cases concerning juveniles who have been tried previously as adults is not binding because it was not essential to the disposition of the appeal in Thenghkam.[30]. Thus, we emphasize that we adhere to the statement in Thenghkam[31] that when a circuit court acquires jurisdiction over a juvenile pursuant to M.C.L. § 712A.4(5), it must impose an adult sentence. In such a case, the court rules and statutory scheme do not provide for a sentencing hearing that focuses on best interests factors because the lack of discretion in the form of sentencing makes the best interests determination irrelevant. With this in mind, it is apparent that Williams, who had already been tried and convicted as an adult by the time the circuit court sentenced him in this case, was not entitled to a sentencing hearing pursuant to MCR 6.931.

VI. Policy Considerations
Even the prosecutor acknowledges that this interpretation of the procedures required when a family court waives jurisdiction under M.C.L. § 712A.4(5) tends to increase the effect of the prosecutor's charging discretion and may lead to unfair results in other cases. For instance, if a prosecutor succeeds in having family court jurisdiction waived and tries a juvenile for a felony in the circuit court, the judge or jury may still acquit the juvenile, the prosecutor may drop the charges, or the circuit court may grant a motion to dismiss.[32] Nevertheless, if the prosecutor thereafter charges the juvenile for another felony, the juvenile must be tried as an adult and, if convicted, sentenced as an adult. This is so even though (a) the juvenile is not a recidivist, having never been convicted of a crime, and (b) a family court trial and a juvenile sentence may be appropriate under the facts of the case. This situation arises because circuit court jurisdiction, not conviction, triggers a trial in the circuit court and, ultimately, an adult sentence.[33] This puts juveniles who are tried for a relatively less serious felony pursuant to M.C.L. § 712A.4(5), even though they had never previously been convicted in an adult trial, in the same sentencing category as juveniles who are tried and convicted of the most heinous crimes under the modern automatic waiver statute.[34]
It may be, as Williams contends, that the Legislature and the Supreme Court intended M.C.L. § 712A.4(5) to interact with MCR 6.901(B) to preclude duplicative best interests hearings in a given case, rather than foreclosing the determination altogether. If so, they failed to make this intent clear. In other words, if the Supreme Court and the Legislature only intended to preclude juveniles in traditional *86 waiver cases who have a history of one or more criminal trials as an adult from having a phase-two hearing and a sentencing hearing, the scheme they set in place does not accomplish this goal. We think it possible that the Legislature and the Supreme Court intended only to have juveniles who were convicted of a felony following a trial in the circuit court, or those who pleaded guilty of a felony in the circuit court, treated this way. Evidence of recidivism may implicate some of the serious and legitimate concerns the Legislature has acknowledged in prescribing adult sentences for juveniles who commit serious crimes and who are subject to automatic waiver to the circuit court without the possibility of a juvenile sentence.
Nevertheless, the language in the relevant statutes and court rules is clear. Whether to change this language to allow a best interests sentencing determination for nonrecidivist juveniles convicted of a felony when they are tried in the circuit court pursuant to M.C.L. § 712A.4(5) is a policy decision. We encourage the Legislature to revisit this issue to ensure that this is the intended sentencing scheme and not an oversight that would allow an unfair and unintended result because the Legislature, not an intermediate appellate court, must make this sort of decision.
Affirmed.

[28]  Error of this type is particularly annoying, rather like a buzzing insect that simply begs for the flyswatter. Like Roger J. Traynor, we observe:

"Errors are the insects in the world of law, traveling through it in swarms, often unnoticed in their endless procession. Many are plainly harmless; some appear ominously harmful. Some, for all the benign appearance of their spindly traces, mark the way for a plague of followers that deplete trials of fairness." [Roger J. Traynor, The riddle of harmless error, p. ix (1970), quoted in Foley & Filiatrault, The riddle of harmless error in Michigan, 46 Wayne L. R. 423, 424 (2000).]
