Defendant appeals his conviction and sentence on a charge of second degree murder. Defendant raises six issues on appeal: (1) the State failed to prove defendant intentionally participated in a common criminal plan unlawfully to kill another human being; (2) the court erred in declining to instruct the jury that prior inconsistent statements of witnesses could be considered as substantive evidence, and not merely as impeachment; (3) the State’s failure to disclose in a timely way certain prospective testimony was prejudicial error; (4) the court erred in rejecting defendant’s requested jury instructions on accomplice liability; (5) the court erred in excluding evidence that defendant’s alleged accomplice had been acquitted, and in instructing the jury that defendant could be convicted as an accessory, despite the alleged accomplice’s acquittal; and (6) assistant judge participation in sentencing was unconstitutional. We affirm. 1
I.
Defendant first claims the State failed to prove that he intentionally participated in a common plan to murder Timothy O’Neal. The question on appeal is “whether the evidence, when
*167
viewed in the light most favorable to the State, is sufficient to convince a reasonable trier of fact that the defendant is guilty beyond a reasonable doubt.”
State
v.
Derouchie,
The evidence, taken in the light most favorable to the State, establishes the following. During the afternoon of April 8, 1982, the victim, Timothy O’Neal, cashed his paycheck and, possessing more than $200, began frequenting bars in the vicinity of the Champlain Mill, a shopping mall in Winooski. By evening, O’Neal was very drunk. Although not violent, he became a persistent nuisance at a bar called “Le Club.” After several female patrons complained, Le Club’s bartender expelled O’Neal, who returned twice more and was expelled each time.
Defendant and a companion, Richard Sorrell, were also patrons at Le Club. After O’Neal’s third expulsion, Le Club’s manager asked defendant and Sorrell, who were then standing outside, to take care of O’Neal and they agreed to do so. Soon thereafter, O’Neal entered Le Club again, to retrieve his coat. Defendant pursued him and pulled him outside before it could be found.
A service road ran between the Champlain Mill and Le Club, leading to a rear parking lot and service entrances. A cement abutment at the rear of the parking lot borders the Winooski River as it runs downstream to a waterfall. An irregular hole in the abutment permits access to the river bank.
Between 11:30 p.m. and midnight, shortly after defendant had pulled O’Neal out of Le Club, a witness saw defendant, O’Neal and Sorrell walking down the service road toward the river. Later, another witness saw two men walking together along the river bank, toward the falls, looking into the water.
Some time after midnight, defendant appeared at his sister’s house, where he kept his clothes. When he arrived, defendant stamped his feet, as though his shoes were wet. Although testimony by the sister was sketchy and conflicting, the jury could reasonably have believed that defendant immediately shut the lights off. While there, he picked up pants, shirt and a pair of shoes, then left after about ten minutes. Two days later, he returned and vacuumed the floor of the house.
After leaving his sister’s house with his change of clothing on the night of the crime, defendant next appeared at his girlfriend’s apartment, noticeably favoring his shoulder. Asked by the occupants how he had gotten blood on the cuffs of his pants, defend *168 ant replied that he had been in a fight and broken the other person’s nose. Defendant later said he’d had a fight with a black man at the Mill Restaurant. At another time he said he had fought two black men there. The Mill Restaurant was closed that night.
After changing his clothes, defendant gave the clothes he had been wearing to his girlfriend and asked her to wash them thoroughly. He then returned with Sorrell to Le Club, where the manager thanked them for helping “take care of the problem” of O’Neal. When the manager asked what had happened to O’Neal, defendant replied, “We lost him” and then volunteered: “He’s pretty much of a ding-a-ling — he was always threatening to commit suicide.”
Defendant and Sorrell began purchasing mixed drinks with large bills, buying drinks for others and leaving large tips. Earlier in the evening, they had purchased beers with exact change, leaving no tips. On the following day, defendant’s brother noticed that, although defendant had been broke the day before, he now had money.
The next morning, Timothy O’Neal was discovered dead in the Winooski River. A trail of smeared blood, drag- and scuff-marks, scrapes and bruises, a lost sneaker and tears in O’Neal’s trousers established that he had been pulled through the hole in the abutment and dragged, head first, face down, for a distance of about 55 feet, then placed in the river: His body snagged on a rock in the rapids above the falls, having been carried 75 yards downstream from the hole in the abutment. He had passed along the part of the river where the two men had been seen walking. There was no money in his wallet, and he wore no outer coat.
The cause of O’Neal’s death was “asphyxia due to drowning” sometime between midnight and 3:00 a.m. Forensic examination determined that, before O’Neal was placed in the water, someone’s arm had been wrapped around his neck in a choke hold, and that he had suffered three or four blows on the head with a large rock. The rock was found nearby, with several of O’Neal’s hairs on it. O’Neal’s hands had sustained injuries, apparently while fending off the blows.
Police investigators questioned defendant. Describing his own activities on the night in question, defendant identified several bars that he had visited but did not mention the Mill Restaurant. Nor did he mention visits either to his sister’s or girlfriend’s homes. He told the police that after a black man, standing with *169 two other black men and a white woman in front of Le Club, warned him to leave O’Neal alone, he never saw O’Neal again.
After defendant’s sister, girlfriend and other relatives were summoned to testify at an inquest, and after defendant learned of the inquest, he and Sorrell announced a trip to Canada and disappeared. Two months later, more than seven weeks after arrest warrants had issued, they surrendered in Florida, telling Florida police that they had been involved in a fight at Le Club.
As is apparent from the preceding summary, the State’s case was built largely upon circumstantial evidence. Circumstantial evidence will sustain a conviction if it is sufficient to convince a reasonable trier of fact that the defendant is guilty beyond a reasonable doubt.
State
v.
Rollins,
II.
Defendant next claims the court erred in declining to instruct the jury that prior inconsistent statements by witnesses could be considered as substantive evidence, and not just for impeachment.
Before the jury retired, defendant approached the bench and objected to the court’s instruction that inconsistent statements, made by witnesses testifying at the previous trial of Sorrell or in depositions, were only to be considered as impeachment. Defendant argued that, because the out-of-court statements had been made under oath, subject to cross-examination, limiting their use to impeachment was erroneous. The court rejected defendant’s argument, citing
State
v.
Dragon,
*170 On appeal, defendant presents several arguments, based upon Vermont common law, the subsequently promulgated Vermont Rules of Evidence, and the Sixth Amendment to the United States Constitution.
A.
At the time of trial, March 16-24, 1983, Vermont’s common law rule of evidence provided that prior inconsistent statements of a testifying witness were not admissible as substantive evidence. The common law rule, last upheld in Dragon, was changed by this Court’s promulgation of V.R.E. 801(d)(1)(A) 2 of the Vermont Rules of Evidence, effective April 1, 1983.
Before April 1, 1983, the trial court was required to apply the common law rule unless presented with persuasive and authoritative reasons to depart therefrom. See
Miller
v.
Willimott,
Defendant’s reference to
State
v.
Lupien,
*171
Nor does
State
v.
Roy,
B.
Despite the express provision in V.R.E. 1102(a) that the Rules of Evidence be inapplicable before April 1, 1983, defendant argues that general rules of retroactivity required application of V.R.E. 801(d)(1) to his trial. Defendant cites two authorities for this theory:
State
v.
Shattuck,
As in other cases considering retroactive application of changes in the law, e.g.,
United States
v.
Johnson,
V.R.E. 1102(a) provides, in pertinent part, that the new rules of evidence apply in “all further proceedings in actions then pending, except to the extent that in the. opinion of the court their application in a particular action pending when the rules take effect would not be feasible or would work injustice, in which event former evidentiary principles apply.” (Emphasis added.) The pertinent language in V.R.E. 1102(a) echoes that of V.R.C.P. 86(a), whose Reporter’s Notes explain, “the court has discretion to mold new provisions to the circumstances in actions pending at the effective date.” However, defendant’s motion for new trial made after April 1, 1983, did not convert the trial court’s March 24 ruling upon his request to charge into a post-April 1 “further proceeding]” within the meaning of V.R.E. 1102(a). Nor has defendant demonstrated how the court’s rejection, based upon Dragon, *172 of his assertion that the rule was wrong, “work[ed] injustice.” V.R.E. 1102(a).
C.
Defendant’s constitutional claims, in essence, maintain that the orthodox common law rule against substantive use of prior inconsistent statements violated both the Sixth Amendment’s Confrontation Clause, and the Sixth Amendment’s provision assuring defendants the right to compulsory process.
(i)
As the United States Supreme Court explained in
California
v.
Green,
In the present case, the evidence on which defendant bases his claim of deprivation consisted of prior out-of-court statements by witnesses, all of whom testified at trial. The identities of all witnesses had been provided to defendant in timely fashion. Defendant had free access to them by pretrial deposition. He was also free to impeach them with their prior statements at trial.
The holding in California v. Green, id. at 164, that the Confrontation Clause permits substantive use of out-of-court statements by a testifying witness who is subject to full cross-examination, did not constitutionally mandate that such statements must be admitted. As the Court stressed in California v. Green, id. at 155, its task was “not to decide which [position], purely as a matter of the law of evidence, is the sounder,” but simply to assess whether defendant’s confrontation right was satisfied.
Although the danger of admitting out-of-court statements is mitigated in circumstances where a testifying witness can be subject to prosecution for perjury, where cross-examination is permitted, and where the factfinder can observe the witness’s demeanor, id. at 158, defendant has not established, either by authority or by force of reason, that the Confrontation Clause requires substantive consideration of prior out-of-court statements, notwithstanding Vermont’s common law rule.
*173 (Ü)
We also reject defendant’s claimed denial of compulsory process. The right of compulsory process originated in reaction to a “notorious” common-law felony rule that did not allow defendants to introduce witnesses.
Washington
v.
Texas,
In this case, defendant was denied no right to put any witness on the stand. See
id.
at 23. Defendant’s real problem is that, once witnesses took the stand, he was dissatisfied by what they said. However, unlike the situation in
Chambers
v.
Mississippi,
III.
Defendant next claims that the State’s failure to disclose in a timely way statements of a key prosecution witness, in violation of V.R.Cr.P. 16(a) and 16.2(b), along with the court’s refusal to delay the trial, requires reversal. The State does not deny its obligation to make continuing disclosure but responds that the court’s order resulted in no prejudice because of defendant’s own decision not to cross-examine the witness.
Two weeks before trial, witness Daniel Tobler told police that he had seen defendant, Sorrell and O’Neal walking toward the river on the night in question. However, the following day, when deposed by defendant, Tobler said he could not identify any of the three.
On Tuesday, the date of jury drawing, Tobler again spoke with police and reverted to his original statement. A copy of the latest statement was given to defense counsel on Wednesday. When the prosecutor visited Tobler on Wednesday night, Tobler explained that he had changed his story at deposition because of a threat against his life.
*174 Defendant’s attorney was informed of Tobler’s explanation on Friday morning, the day on which Tobler was scheduled to testify. Defendant requested that Tobler’s direct testimony be continued until defendant could further investigate the story and depose Tobler again.
The court decided to proceed with Tobler’s direct testimony, in part because the jury was sequestered. The court authorized the State to question Tobler, subject to the condition that it not refer to the threat. The court authorized defendant to cross-examine Tobler fully on Friday afternoon, and also to recall Tobler for further examination, if desired after further investigation and redeposition.
On Friday afternoon, Tobler’s direct testimony passed without mention of the threat. Thereupon, defendant did not cross-examine him that day, nor did defendant ever recall him for further testimony.
Defendant claims that his lack of opportunity to investigate the new information before Tobler testified was prejudicial error. However, Tobler’s testimony did not address the new information, and defendant in fact was granted all the time he needed to investigate Tobler’s recantation. Compare
State
v.
Evans,
Defendant’s claim that he was denied immediate cross-examination is unsupported. Examination of the record reveals that he declined the opportunity. Further, defendant could have recalled Tobler to the witness stand at any time.
“Control of the order of proof and the limits of cross examination are of necessity committed to the trial judge who is responsible for the orderly progress of the trial. To be sure, his discretion must be soundly applied, with detached patience, understanding and fairness.”

Citing
State
v.
Carter,
In accordance with 13 V.S.A. § 3, the court instructed the jury that a finding of participation “in the execution of the unlawful design” would support conviction and that “[m]ere presence . . . is not enough to establish participation. . . .” The court’s instruction was a correct statement of Vermont law, allowing accessories to be adjudicated guilty as principals. “[T]he issue on review is simply whether a jury could reasonably conclude beyond a reasonable doubt that a preconceived [criminal] plan existed in which defendant participated.”
State
v.
Bissonette,
Defendant’s objection to the instructions focuses upon the court’s failure to instruct the jury that, in order to convict, the common plan of defendant and Sorrell must have been to kill O’Neal, not merely to rob him. Defendant claims that the court’s instruction permitted the jury to convict defendant for second degree murder if it found that defendant merely shared a goal to rob O’Neal. In essence, defendant claims that the charge allowed conviction for “felony murder.”
When reviewing a court’s charge, we must view it as a whole rather than piecemeal.
State
v.
Carter,
The evidence recited in Part I,
supra,
is sufficient to support a conclusion that defendant participated in the criminal act of second degree murder as a principal. As in
Barr, supra,
We find no error in the instructions.
V.
Defendant claims that the court erred by excluding evidence of the acquittal of defendant’s alleged accessory, Sorrell, after jury trial, and by instructing the jury that defendant could be convicted as an accessory, despite Sorrell’s acquittal. This was not error.
Evidence that a jury has acquitted one of a group of alleged conspirators is not admissible to prove the innocence of an alleged co-conspirator, nor is the alleged co-conspirator entitled to a directed verdict of acquittal.
Burt
v.
United States,
Similarly, the acquittal of an alleged principal does not collaterally estop the prosecution from seeking conviction of an
*177
alleged aider and abettor.
Standefer
v.
United States,
In Vermont there is no distinction between accessories before the fact and principals, and an accessory before the fact may be informed against, tried, convicted and punished as a principal.
State
v.
Sears, supra,
VI.
At trial, defendant unsuccessfully challenged the participation of assistant judges at sentencing, claiming that, as county executives, their control of the sheriff’s department budget prevented them from acting as impartial magistrates.
On appeal, defendant restructures his argument and for the first time claims that the participation of lay assistant judges denied him his constitutional rights to effective assistance of counsel, due process of law, and equal protection. Because these claims were not raised below, we will address them only if the assistant judges’ participation in the sentencing amounted to plain error.
State
v.
Turner,
We have previously held, and reiterate here, that the participation of lay assistant judges at sentencing does not deny a defendant due process of law or the effective assistance of counsel.
State
v.
Hunt,
Under his equal protection claim, an issue not addressed by our decision in
Hunt,
defendant contends that the State’s filing of the case in superior court, which is presided over by a law-trained superior judge and two assistant judges (usually lay persons), rather than in district court, where trial is before a single law-trained district judge, arbitrarily and unjustly obtained treatment more favorable to the State. Defendant’s brief incorporates, by reference, legal arguments presented by other defendants in unrelated cases, without making any attempt to set forth the substance of his arguments for the benefit of the Court or opposing counsel. This constitutes inadequate briefing.

v.
Settle,

Affirmed.
Notes
We do not reach the State’s cross-appeal, challenging the court’s suppression of statements given by defendant to the police.
V.R.E. 801(d)(1) provides in part:
A statement is not hearsay if . . . [t]he declarant testifies at the trial or hearing and is subject to cross-examination concerning the statement, and the statement is (A) inconsistent with his testimony, and was given under oath subject to penalty or perjury at a trial, hearing, or other proceeding, or in a deposition ....
