Boston Municipal Court: What Happens at Each Stage of a Criminal Case

A person summoned to the Boston Municipal Court, or released after an arrest with a date to appear there, usually has one question: what will happen. This guide describes each stage of a criminal case in the Boston Municipal Court, from the first hearing to the last, so that a defendant understands what each stage decides before standing in the courtroom.

The Boston Municipal Court, known in practice as the BMC, hears most criminal cases that arise in the City of Boston, and it resolves most of them as well. The court’s structure, its jurisdiction, and its procedure shape every decision a defendant makes.

This page follows a case through one court. The statewide sequence appears on the Massachusetts criminal process page, and the courtroom stages appear in the criminal court practice section.

The Eight Divisions of the Boston Municipal Court

The BMC sits in eight divisions across the City of Boston, each with its own courthouse and territory, and this page follows the procedure of a case in any of them. For the divisions themselves, the courthouse locations and neighborhoods, the charges each division sees most often, and Attorney Serpa’s representation in those courtrooms, see the firm’s Boston Municipal Court criminal defense page.

The Criminal Jurisdiction of the Boston Municipal Court

The court’s criminal jurisdiction is set by G.L. c. 218, § 26. The BMC has jurisdiction, concurrent with the Superior Court, over all misdemeanors except libel, over all felonies punishable by imprisonment in the state prison for not more than five years, and over the additional offenses listed in § 26 itself. A house of correction alternative in a felony statute does not by itself bring the felony within the BMC’s final jurisdiction.

Two consequences follow. First, a felony outside those categories must be prosecuted in the Superior Court on an indictment, although such a case ordinarily begins in the BMC with an arraignment and a bail decision before it is bound over or indicted. Second, the BMC may impose the same penalties as the Superior Court for the crimes within its jurisdiction except a sentence to the state prison, G.L. c. 218, § 27. A committed sentence from the BMC runs to the house of correction, where a term for a single offense does not exceed two and one half years. The difference between the two commitments is explained on the firm’s page on Massachusetts courts, state prison, and the house of correction.

How a Case Begins

BMC follows fundamentally the same rules as the Massachusetts district courts regarding how criminal cases begin. This firm covers the process in detail here.

A criminal case arrives at the BMC in one of three ways. A person who was arrested is brought to court for an arraignment, usually on the next business day. A person who was not arrested and instead received a summons will be ordered to appear either for arraignment or a clerk magistrate hearing. A clerk magistrate hearing, held under G.L. c. 218, § 35A before any complaint issues, can prevent a criminal record from being created at all, whether the state-level CORI or an FBI rap sheet.

The Clerk Magistrate Hearing

When a complaint application is filed without an arrest, a clerk magistrate holds a show cause hearing to decide whether a criminal complaint should issue. The standard is probable cause, and the clerk magistrate also has discretion to decline the complaint, to hold the application open, or to resolve the matter short of a criminal charge.

Who receives a hearing is set by G.L. c. 218, § 35A. A person not under arrest is entitled to notice and a hearing on a misdemeanor application. On a felony application, the hearing is held at the request of law enforcement, and a privately filed felony application is heard at the clerk magistrate’s discretion. The statute also permits process to issue without a hearing where there is an imminent threat of bodily injury, of the commission of a crime, or of flight.

The hearing matters because a complaint that never issues means there is no arraignment, and in Massachusetts the arraignment is what creates the CORI entry.

When the clerk magistrate denies an application in a matter that began without an arrest, there has been no booking or fingerprint submission either, so the matter creates no state CORI entry and no FBI identity record. The police report remains in the police department’s files. The firm’s page on clerk magistrate hearings in Massachusetts and its clerk magistrate hearing FAQ cover the hearing in detail; it is the stage at which early representation accomplishes the most.

The Arraignment

The arraignment is the formal start of the case. The charges are read, a plea of not guilty is entered, the judge addresses bail and conditions of release, and the court sets the next date. The hearing is usually brief, and it is also the moment the case enters the Criminal Offender Record Information system, because the CORI entry is created at arraignment rather than at conviction. What that record contains, and who can see it at each level of access, is explained on the firm’s page on Massachusetts criminal records.

Bail and Conditions of Release

At arraignment the court decides the terms of release while the case is pending. In most BMC cases the defendant is released on personal recognizance, a promise to return, sometimes with conditions such as staying away from a complaining witness or abstaining from alcohol. Bail in Massachusetts secures the defendant’s return to court; it is not punishment. In a narrow set of serious cases the Commonwealth may instead move for a dangerousness hearing under G.L. c. 276, § 58A, after which the court may hold the defendant for trial or impose strict conditions of release. In a domestic violence case a companion abuse prevention order under c. 209A is often in place at the same time, a combination addressed on the firm’s domestic violence defense page.

The Pretrial Conference and Discovery

After arraignment the case moves through pretrial and compliance dates. The Commonwealth produces discovery: police reports, witness statements, booking video, breath test records, and the other evidence it intends to use. The parties complete a pretrial conference report that tells the court where the case stands. Most of the defense work happens at this stage, in reading the discovery closely, identifying what the Commonwealth cannot prove, and selecting the motions worth filing. The full sequence is set out in the firm’s overview of the Massachusetts criminal process.

Pretrial Motions

Where the facts or the law support it, the defense files motions before trial. A motion to suppress asks the court to exclude evidence obtained in violation of the defendant’s rights, such as an unlawful stop, a warrantless search without a valid exception, or a statement taken without the required warnings. A motion to dismiss challenges a complaint that is defective or unsupported by probable cause. A successful suppression motion often ends the prosecution, because the excluded evidence was the Commonwealth’s proof.

Dispositions Without a Trial

Most BMC cases resolve without a trial, and the available dispositions differ sharply in their consequences. An outright dismissal, a dismissal on court costs, and pretrial probation under G.L. c. 276, § 87 each end the case without an admission and without a finding of guilt.

A continuance without a finding is different. The defendant admits that the facts are sufficient for a guilty finding, the case is continued on probation conditions, and it is dismissed on successful completion.

A continuance without a finding is not a conviction under Massachusetts law. It generally satisfies the federal immigration definition of a conviction, because the admission to sufficient facts is followed by probation or another punishment, penalty, or restraint on liberty, and the disposition can affect professional licensing and a driver’s license. The distinctions are set out in the firm’s continuance without a finding, pretrial probation, and diversion FAQ, and the choice among dispositions should be made with the record consequences in view.

Trial Before a Jury of Six

A case that does not resolve is tried. Under G.L. c. 218, § 26A, trial of criminal offenses in the Boston Municipal Court is by a jury of six, and a defendant who files a written waiver may instead be tried by a judge without a jury. The Commonwealth must prove every element of the offense beyond a reasonable doubt, and the defense tests that proof through cross examination of the Commonwealth’s witnesses and, where appropriate, evidence of its own.

Sentencing

If the case ends in a guilty finding or an admission, the court imposes sentence: commonly probation or a fine, and in the more serious cases a committed term in a house of correction within the limit of § 27. Probation carries conditions, and an alleged violation brings a surrender hearing decided on a lower standard of proof than a trial, a proceeding covered on the firm’s probation violation defense page.

The Record After the Case

A record of the case remains after the case ends. Depending on the disposition, the entry may later be sealed or, in narrower circumstances, expunged; the waiting periods and standards are covered on the firm’s page on sealing and expunging a Massachusetts criminal record. For many defendants the record, not the sentence, is the lasting risk, because a background check years later can affect employment, housing, licensing, and immigration status.

Students, Licensed Professionals, and Noncitizens

Three groups face the sharpest collateral consequences in the BMC. A college or university student faces a parallel school disciplinary process alongside the criminal case, a combination addressed on the firm’s student criminal defense page, and a night downtown that ends in a fake ID charge at the Central Division is one of the most common ways a student acquires a record; the firm’s post on BMC Central and the downtown nightlife docket describes that pattern. A licensed professional can face board reporting duties and discipline from a disposition that is not a conviction. A noncitizen can face immigration consequences from a plea that a citizen would consider minor. Two of the most common BMC charges, operating under the influence and assault and battery on a family or household member, carry exactly these risks.
