OPINION

Chief Justice SUTTELL, for the Court.

The defendant, Parrish Chase, appeals from a Superior Court order denying his motion to reduce sentence under Rule 35 of the Superior Court Rules of Criminal Procedure. As grounds for his appeal, the defendant argues that (1) he was entitled to the appointment of counsel; (2) he was denied a meaningful hearing because the trial justice failed to address several issues that he had raised; and (3) he was denied an opportunity to challenge the constitutionality of the state manslaughter statute, G.L.1956 § 11-23-3. This case came before the Supreme Court for oral argument pursuant to an order directing the parties to appear and show cause why the issues raised in this appeal should not be summarily decided. After reviewing the record and considering the parties' written and oral submissions, we are satisfied that this appeal may be decided without further briefing or argument. For the reasons set forth in this opinion, we affirm the order of the Superior Court.

Facts and Procedural History

On October 17, 2000, a grand jury indicted defendant on two counts of first-degree murder in connection with the stabbing deaths of William Sencabaugh and Robert Bishop in Woonsocket. Pursuant to a plea agreement with the state, Mr. Chase pled guilty to two amended counts of manslaughter on September 30, 2004. The plea agreement came to fruition as a result of medical expert reports from Peter R. Breggin, M.D., retained by defendant, and Barry Wall, M.D., retained by the state, which indicated that defendant's ingestion of alcohol and prescription drugs, including Prozac, Elavil, Effexor, Xanax, and Vicodin, rendered him unable to form the requisite intent to commit murder.1

Consistent with the terms of the plea agreement, the trial justice sentenced defendant to two consecutive thirty-year sentences. The defendant was ordered to serve thirty years (fifteen years per count) at the Adult Correctional Institutions, with the remaining thirty years (fifteen years per count) suspended, with probation.

On January 27, 2005, defendant filed a timely pro se motion to reduce his sentence pursuant to Rule 35. The Rule 35 motion did not set forth any grounds for relief, but indicated that defendant would present such grounds at a later date. On April 15, 2005, the trial justice entered an order instructing defendant to file a memorandum on or before May 10, 2005, setting forth grounds to support his sentence-reduction motion. The defendant filed a memorandum asserting such grounds on May 9, 2005. On May 19, 2005, defendant also filed several pro se motions related to his Rule 35 motion, including a motion to assign a hearing date, a motion to appoint counsel with an accompanying affidavit of indigency, a motion for an evidentiary hearing, and a "[m]otion for [s]entence [s]urvey" requesting "all [m]anslaughter sentences from 1991 thru [sic] 2001 and any other pertinent information associated with these cases that will establish their degree of culpability or [d]iminshed [c]apacity." There is no indication in the docket or record that the trial justice ruled on these motions. The trial justice did, however, issue an order denying defendant's Rule 35 motion on June 17, 2005. A motion to reconsider was filed by defendant. It was likewise denied.

On appeal, this Court vacated the Superior Court order denying the motion to reduce and remanded the case to the Superior Court for a hearing and reconsideration of the motion. State v. Chase, 958 A.2d 147, 149 (R.I.2008) (mem.). On November 24, 2008, the day before the scheduled hearing, defendant filed a motion to challenge the constitutionality of the state manslaughter statute and a supplemental brief setting forth reasons why his motion to reduce should be granted. In addition, on the day of the hearing defendant submitted a motion for a sentencing survey and remission of costs.

On November 25, 2008, a hearing was held on defendant's motion to reduce. The defendant was present and explained that he was seeking "leniency" based on "changed circumstances" arising from new information concerning potential homicidal ideations caused by the prescription drugs that he had been taking when he committed the crimes. The defendant also argued that the sentencing benchmark should be lowered and that he should be at "the low end" of the benchmark. The defendant did not address his other pending motions, including his request for counsel.

After hearing defendant's arguments and the state's objections, the trial justice made a bench ruling denying the sentence-reduction motion. In denying the motion, the justice stated, in relevant part:

The defendant filed a motion for rehearing that was denied on January 7, 2009, and on January 22, 2009, the Superior Court entered an order denying defendant's motion to reduce. The defendant prematurely filed a notice of appeal on January 8, 2009.2

We will address defendant's issues raised on appeal seriatim.

Discussion

A

Assignment of Counsel

A criminal defendant's right to counsel "flows from different constitutional provisions[,] depending on the nature of the proceedings." United States v. Palomo, 80 F.3d 138, 141 (5th Cir.1996). More specifically, the Sixth Amendment to the United States Constitution3 provides a criminal defendant with the right to counsel during all "`critical stages'" of a criminal prosecution, State v. Oliveira, 961 A.2d 299, 308-09 (R.I.2008), "where substantial rights of a criminal accused may be affected."4 Mempa v. Rhay, 389 U.S. 128, 134, 88 S.Ct. 254, 19 L.Ed.2d 336 (1967). Additionally, the Due Process Clause of the Fourteenth Amendment to the United States Constitution5 provides for a right to counsel in certain postconviction proceedings when "fundamental fairness necessitates the assistance of a trained advocate." Palomo, 80 F.3d at 141.6

In the instant case, defendant does not assert a constitutional right to counsel under either the Sixth Amendment or the Due Process Clause of the Fourteenth Amendment. He argues, rather, that he was entitled to the appointment of counsel in connection with the Rule 35 proceedings pursuant to Rule 44 of the Superior Court Rules of Criminal Procedure. The proper construction of a court rule is a question of law to which we apply a de novo standard of review. State v. Brown, 898 A.2d 69, 76 (R.I.2006).

Rule 44 states that

We decline to read into Rule 44 a requirement that counsel be assigned to represent a defendant at a sentence-reduction hearing under Rule 35. It is well established that a Rule 35 motion to reduce sentence "is `essentially a plea for leniency' * * * addressed to the sound discretion of the trial justice, who may grant it if he or she decides `on reflection or on the basis of changed circumstances that the sentence originally imposed was, for any reason, unduly severe.'"7 State v. Mendoza, 958 A.2d 1159, 1161 (R.I.2008) (quoting State v. Burke, 876 A.2d 1109, 1112 (R.I.2005) and State v. Furtado, 774 A.2d 38, 39 (R.I.2001)). A motion to reduce sentence is by its very terms a posttrial proceeding; a judgment of conviction has been entered, and a sentence has been imposed. Such a proceeding is not a criminal prosecution, and thus it is our opinion that it is not a "stage of the proceeding" to which the procedural right to counsel under Rule 44 attaches. See Palomo, 80 F.3d at 142 (motion under Rule 35(b) of the Federal Rules of Criminal Procedure "is not a trial-related proceeding").

Here, the sentence imposed on defendant, thirty years on each count, was not only authorized by statute,8 but it also was the very sentence that defendant agreed to serve as part of the plea bargain. Moreover, there was no motion to increase defendant's sentence pending, as permitted by Rule 35(b). Thus, Mr. Chase was not confronted with the prospect of any additional loss of liberty. In the context of this case, we need not address the question of whether the dictates of fundamental fairness and due process might require an indigent defendant to be appointed counsel in a Rule 35 proceeding in an appropriate case. This is clearly not such a case.

B

Denial of Motion to Reduce

The defendant next argues that the denial of his motion to reduce was improper because the trial justice ignored his information concerning prescription drugs and benchmark comparisons, the trial justice failed to rule on his request for statistics about other manslaughter convictions, and because there were no aggravating circumstances to justify consecutive sentences.

Our review of a trial justice's decision on a Rule 35 motion "is extremely limited," State v. Sifuentes, 667 A.2d 791, 792 (R.I.1995), as "[t]his Court has maintained a `strong policy against interfering with a trial justice's discretion in sentencing matters.'" State v. Rossi, 771 A.2d 906, 908 (R.I.2001) (mem.) (quoting State v. Mollicone, 746 A.2d 135, 137 (R.I.2000)). A trial justice's ruling on a motion to reduce sentence will be disturbed "only when the sentence is without justification." State v. Brown, 755 A.2d 124, 125 (R.I. 2000) (quoting State v. Brigham, 666 A.2d 405, 406 (R.I.1995)). "It is the defendant's burden to show that the sentence imposed violates this standard." State v. Cote, 736 A.2d 93, 94 (R.I.1999) (mem.).

The defendant states, as grounds for appeal, that the trial justice improperly failed to address "new and substantial" evidence presented in regard to the effects of various prescription drugs, specifically Effexor and Prozac, and that he failed to address information concerning sentencing benchmark comparisons. At the hearing held on November 25, 2008, the trial justice heard defendant's arguments on these matters. The defendant pointed out that the Food and Drug Administration now requires labeling for Effexor that explains it may cause homicidal ideations. In response, the state argued that this was not "new information" because defendant was well aware at the time of the plea agreement that the medications had an effect, and that the additional information simply pertained to the degree of effect that the medication may have had. The defendant also set forth his argument that his sentence should be more in accord with other benchmark sentences, including the "10-year threshold of benchmark number 27."9 In response to this, the state noted that the sentence was in accord with a plea bargain that took into consideration the reduction of the charges from murder to manslaughter.

The trial justice then stated that he had a "clear recollection of this plea, because it was so unusual." He proceeded to explain that it was "unusual in the sense that [defendant's attorney] was able to get two murder charges for first degree rolled down to manslaughter," acknowledging that "there was ample medical evidence indicating the drugs that [defendant] had ingested." The trial justice concluded by explaining to defendant that, "[e]ven if I had known what you're professing to tell me now, it wouldn't have made any difference, in my view, having killed two people, having had the sentences reduced to a level of manslaughter, you were the beneficiary of a marvelous effort by your lawyer to get you what you got." We agree. The effect of the drugs and alcohol upon defendant is precisely what caused the court to accept the plea agreement reducing the two counts of first-degree murder to manslaughter. The trial justice clearly indicated that defendant's "new" information, even presuming it was unavailable at the time of sentencing, would not have caused the trial justice to impose a lighter sentence.

Although defendant correctly asserts that a plea agreement does not preclude him from later filing a motion to reduce pursuant to Rule 35, this Court has recognized that "it is certainly proper for motion justices to accord this factor considerable significance in deciding whether to exercise their discretion to grant the motion [to reduce]." State v. Miller, 694 A.2d 748, 749 (R.I.1997) (mem.). In denying the motion, the trial justice explained to defendant, "[y]ou got your just results that you bargained for." The record is clear, and defendant does not challenge, that he knowingly, intelligently, and upon advice of counsel, entered into the plea agreement. Certainly the trial justice was acting well within his discretionary authority to take this factor into account in denying defendant's Rule 35 motion.

Furthermore, defendant argues that the trial justice improperly ignored his request for statistical information. We are satisfied, however, that any statistical information about a disparity between defendant's sentence and those imposed on others convicted of manslaughter would have had a minimal impact on defendant's sentence-reduction motion. This Court has recognized that a list of sentence comparisons is not adequate to meet the heavy burden that a defendant must satisfy on a motion to reduce. State v. Morris, 863 A.2d 1284, 1288-89 (R.I.2004). This Court acknowledges that because "every sentencing presents different and potentially unique circumstances * * * any comparison of sentences can be misleading, especially if too much reliance is placed on this one factor in assessing whether a sentencing justice was justified * * *." State v. Ballard, 699 A.2d 14, 16 (R.I.1997), abrogated on other grounds, State v. Coleman, 984 A.2d 650 (R.I.2009). Therefore, we are of the opinion that the trial justice did not err by denying the sentence-reduction motion without first providing or considering the statistical information requested by defendant.

Finally, defendant argues that the denial of his motion to reduce was improper because consecutive sentences are impermissible absent aggravating circumstances. The proposition that defendant sets forth is inapplicable to the circumstances in this case. In Ballard, 699 A.2d at 18, this Court indicated its preference for concurrent sentences when multiple offenses are committed during a single course of action, unless aggravating or extraordinary circumstances are presented; however, in Coleman, 984 A.2d at 656, this Court made clear that this holding from Ballard is "of little or no precedential value." Furthermore, in State v. Collins, 714 A.2d 610, 611 (R.I.1998) (mem.), this Court explained that consecutive sentences are justified when serious harm is suffered by each victim as a consequence of a defendant's "single" criminal act. Here, defendant pled guilty to fatally stabbing two persons, and the imposition of the consecutive sentences was, in fact, the result of defendant's plea agreement to serve such sentences consecutively in consideration for the state amending the charges down to manslaughter. On these facts, we find defendant's argument to be unpersuasive.

C

Constitutionality of § 11-23-3

Finally, the defendant attempts to challenge the constitutionality of the state manslaughter statute, § 11-23-3. The defendant seems to assert that at the time of the offenses he had "diminished capacity" from a "mental disability," which he argues the manslaughter statute must "distinguish and or recognize." The defendant has, however, failed to provide any legal support for his argument. This Court has held that "[s]imply stating an issue for appellate review, without a meaningful discussion thereof or legal briefing of the issues, does not assist the Court in focusing on the legal questions raised, and therefore constitutes a waiver of that issue." Wilkinson v. State Crime Laboratory Commission, 788 A.2d 1129, 1131 n. 1 (R.I.2002); see also Tondreault v. Tondreault, 966 A.2d 654, 664-65 (R.I.2009). Because of the lack of adequate briefing, we accordingly deem this argument waived.
