A Motion for New Trial, pursuant to Rule 30 of the Massachusetts Rules of Criminal Procedure, may be used by a Defendant who is challenging the validity of a guilty plea. A Judge should only grant a post sentence motion to withdraw a plea if the Defendant comes forward with a credible reason which outweighs the risk of prejudice to the Commonwealth.
A Trial Judge has the discretion to grant a new trial at any time it appears an injustice was done. After a Defendant has been tried and convicted, he may have grounds to move the court for a new trial for many reasons.
Generally, the common causes for which a new trial may be granted fall into two categories: One category includes occurrences at trial or in the jury’s verdict which demonstrates that an injustice has been done; and the other category is the discovery of new evidence after the trial, or other developments occurring after the trial or conviction, which demonstrates manifest injustice.
