Commonwealth vs. a Juvenile
The defendant juvenile was charged in a District Court complaint with delinquency by reason of committing, on January 10, 1980, assault and battery by means of a dangerous weapon, in violation of
1. On appeal to a jury session of a Juvenile Court from an adjudication of delinquency, a juvenile is entitled to a jury of twelve “in those cases where trial would be only upon an indictment were the child an adult.”
We are unable to determine that the motion wаs not filed in a timely fashion. The judge had discretion to allow the motion to be filed at the time it was filed. See
The Commonwealth nеxt contends that, even if the defendant was deprived of his statutory right to a jury of twelve, that error did not prejudice him and, therefore, reversal of the adjudication of delinquency is not required. Ordinarily, statutory violations are not grounds for reversal unless the violation caused some harm. See
Commonwealth
v.
Hartford,
The question then is whether the statutory right to a twelve-person jury is sufficiently substantial so as to require protection of the right, even in the аbsence of any demonstrable prejudice to the defendant. Certainly, no defendant could prove that he was prejudiced by the reduction of the size of the jury, any more than the Commonwealth could prove that he was not. It may be true that the defendant did not have a constitutional right to a jury of twelve. See
Opinions of the Justices,
The statutory right tо a jury of twelve was a substantial right, and that right should have been protected, even in the absence of any demonstration of actual prejudice arising from thе denial of that right. We conclude, therefore, that the violation of
2. Because the issue may arise again on retrial, we briefly dispose of the defendant’s claim that the judge erred in not allowing the defendant to impeach the victim’s credibility by reference to the victim’s juvenile record. That record contained charges of delinquency by reason of breaking and entering and larceny of a motor vehiсle. A judge, in that case, had continued the charges for disposition after finding sufficient facts to warrant a finding of delinquency. Those charges had no apparеnt relation to the crime for which this defendant was adjudicated delinquent. We shall assume, without deciding, that the judge’s action was the equivalent of a finding of delinquency.
In this case, the defendant asserts that because the case against him rested on the credibility of the juvenile victim’s testimony, the defendant should have been allowed to attack that credibility through use of the victim’s juvenile record. We have already rejected such a general contention. Commonwealth v. Santos, supra at 923-924. On the sparse record before us, we discern no special circumstances that would mandate admissibility of the record.
3. The adjudication of delinquency from which the juvenile defendant has appealed is reversed and the case is remanded for a new trial to a jury of twelve persons consistent with this opinion.
So ordered.
Notes
The Commonwealth disclaims any reliance on the amendment of
If the Commonwealth had relied on the 1980 amendment, we would be faced with the question whether apрlication of an amendment enacted
There would be the initial question, in any event, whether, as a matter of statutory construction “under the influence — if not the command” of ex post facto provisions, we would read the 1980 amendment as prospective only. See
