Massachusetts Criminal Procedure Rule 27: Verdict
(Applicable to jury trials in District Court and Superior Court)
(a) Return. The verdict shall be unanimous. It shall be a general verdict returned by the jury to the judge in open court. The jury shall file a verdict slip with the clerk upon the return of the verdict.
(b) Several Offenses or Defendants. If there are two or more offenses or defendants tried together, the jury may with the consent of the judge at any time during its deliberations return or be required by the judge to return a verdict or verdicts with respect to the defendants or charges as to which a verdict has been reached; and thereafter the jury may in the discretion of the judge resume deliberation. The judge may declare a mistrial as to any charges upon which the jury cannot agree upon a verdict; provided, however, that the judge may first require the jury to return verdicts on those charges upon which the jury can agree and direct that such verdicts be received and recorded.
(c) Special Questions. The trial judge may submit special questions to the jury.
(d) Poll of Jury. When a verdict is returned and before the verdict is recorded, the jury may be polled in the discretion of the judge. If after the poll there is not a unanimous concurrence, the jury may be directed to retire for further deliberations or may be discharged.
