Massachusetts Criminal Process: From Clerk-Magistrate Hearing to Trial and Appeal

A Massachusetts criminal case can begin with a complaint application, an arrest, or a grand jury indictment. The route then may include arraignment, bail, discovery, pretrial motions, a negotiated disposition or trial, sentencing, probation, appeal, and criminal-record consequences. This page explains those stages in the order they usually occur and links to the detailed page for each stage.

This page addresses procedure. The Massachusetts criminal defense practice areas page covers particular charges and the separate consequences for students, licensed professionals, and noncitizens.

Attorney Joe Serpa has practiced Massachusetts criminal defense since 1995. He represents defendants in the Boston Municipal Court, the District Courts of Eastern Massachusetts, and the Superior Court at the stages described below.

The Sequence and Its Variations

Few cases pass through every stage. A clerk-magistrate may decline to issue a complaint, the Commonwealth may enter a nolle prosequi, or a judge may allow a motion to dismiss. Many cases end through a negotiated disposition before trial.

Some cases leave the sequence at the beginning. Under M.G.L. c. 276B, § 2, a juvenile or adult defendant may enter a community-based restorative justice program before arraignment with the consent of the district attorney and the victim. Successful completion produces dismissal and can end the charge without an arraignment or a CORI entry from that charge.

The order also varies by court. A District Court or Boston Municipal Court case ordinarily begins with a complaint. A Superior Court case begins with a grand jury indictment, so the grand jury comes before arraignment. When police make an arrest, the case ordinarily proceeds without a clerk-magistrate hearing.

Investigation and the Complaint Application

Before any court date, police investigate and then apply for a criminal complaint, or arrest first and apply afterward. The application identifies the requested charge and the facts offered to support it. An arrest ordinarily determines whether a clerk-magistrate hearing is available. How criminal cases begin in Massachusetts District and Boston Municipal Courts explains the three ways a case can begin and the rules for each.

Where the case began with a vehicle stop, the legality of the stop is examined first. Massachusetts Traffic Stops, Exit Orders, and Pretext Searches covers what an officer may do at each step of the encounter. Anything a person said to police during the investigation is examined at the same time. See Your Right to Remain Silent in Massachusetts.

The Clerk-Magistrate Hearing

A clerk-magistrate hearing under M.G.L. c. 218, § 35A is held before a complaint issues. The clerk-magistrate decides whether probable cause exists, and retains discretion to decline the application or to hold it open even where the standard is met. The hearing is presumptively private. A magistrate may open it only where the application is of special public significance and the legitimate interest of the public outweighs the accused person’s right of privacy.

If the clerk-magistrate denies the application, no complaint issues, no arraignment occurs, and that application creates no CORI entry. The denial is the practical end of nearly every ordinary case, although it is not technically a final judgment. A later application is possible in exceptional circumstances, most commonly after new alleged conduct or a repeat offense, and remains subject to the applicable limitation period. M.G.L. c. 277, § 63 sets a six-year period for most crimes and longer periods for specified offenses.

A person accused of a misdemeanor motor vehicle offense with no accompanying felony is entitled to a hearing before a complaint issues. The request must be made in writing within four days of the violation. M.G.L. c. 90C, § 3. Clerk-Magistrate Hearings in Massachusetts covers who receives a hearing, what the magistrate may consider, and the rulings available. Massachusetts Motor Vehicle Crimes and the Uniform Citation covers the citation itself.

Grand Jury Indictment and the Superior Court

A Superior Court felony case begins with a grand jury indictment. The defendant is excluded from the proceeding and the standard is probable cause. A defendant charged with an offense punishable by state prison has the right to be proceeded against by indictment. The exception is an offense within concurrent jurisdiction that the District Court retains. M.G.L. c. 263, § 4. That right may be waived under § 4A.

The District Court and the Boston Municipal Court have original jurisdiction concurrent with the Superior Court. It covers all misdemeanors except libel, all felonies punishable by imprisonment in the state prison for not more than five years, and a list of named offenses. M.G.L. c. 218, § 26. Those courts may impose the penalties the Superior Court could impose for an offense within their jurisdiction, except a state prison sentence. M.G.L. c. 218, § 27.

Prosecution in a District Court does not convert a felony into a misdemeanor. Commonwealth v. Lightfoot, 391 Mass. 718 (1984). The felony or misdemeanor classification governs the charging route, the sealing waiting period, and the sentencing exposure. Which court hears the case determines whether a committed sentence runs to the house of correction or to state prison.

Arrest, Summons, and Warrants

Where police arrest, the defendant is booked and brought before the court on the next court day. Where police do not arrest, the court issues a summons directing the defendant to appear for arraignment on a stated date. A defendant who does not appear defaults, and the court issues a warrant.

A warrant remains active until it is removed. Warrants entered in the warrant management system are accessible through the criminal justice information system to law enforcement agencies and to the Registry of Motor Vehicles. M.G.L. c. 276, § 23A. A licensing authority that learns of an outstanding default or arrest warrant must notify the licensee. The notice states that the license will be suspended unless the licensee shows within thirty days that the warrant has been recalled or that none is outstanding. M.G.L. c. 276, § 23B. The licensee may request a hearing, and the authority issues a finding within forty-five days of it.

A planned voluntary surrender allows counsel to address the warrant and present bail information when the defendant appears. Warrants and arrests in Massachusetts courts explains the arrest process. Removing a Massachusetts warrant explains how counsel can ask the court to recall the warrant and address bail after a default.

Arraignment

Arraignment is the first formal court appearance. The charge is read, counsel is appointed or confirmed, a not guilty plea is entered, and conditions of release are set. Arraignment also creates the entry in the criminal offender record information system, whatever the eventual outcome of the case.

What a person outside the case may see of that entry depends on that requester’s authorized level of access under M.G.L. c. 6, § 172. Criminal justice agencies may obtain all criminal offender record information, including sealed records, for the performance of their criminal justice duties. Employers, landlords, volunteer organizations, and licensing bodies obtain a narrower set, which includes pending charges and a continuance without a finding until the case is dismissed. A member of the general public obtains less again.

Arraignment in Massachusetts covers the proceeding and the options that close once it occurs.

Bail, Conditions of Release, and Dangerousness

Bail in the District Court and the Boston Municipal Court is set under M.G.L. c. 276, § 58, and in the Superior Court under § 57. A judge must consider the defendant’s financial resources. Some defendants cannot post the amount set, so that indigency is likely to result in long-term pretrial detention. In that situation the judge must make written or orally recorded findings of fact and state the reasons for the decision. Brangan v. Commonwealth, 477 Mass. 691 (2017).

A judge may not set an unaffordable amount in order to hold a defendant thought to be dangerous. The presumption of release, the factors, the six hour rule, and Superior Court review are covered on the Massachusetts bail page. Where the Commonwealth seeks detention on that ground, it must move under M.G.L. c. 276, § 58A, and comply with the procedure that section requires. The predicate offenses, the evidentiary standard, and how the defense prepares are covered on the dangerousness hearing page.

The § 58A hearing is held immediately on the defendant’s first appearance unless it is continued. A continuance may not exceed seven days on the defendant’s motion or three business days on the Commonwealth’s. Absent good cause, detention under the section may not exceed 120 days in the District Court or 180 days in the Superior Court, excluding delay defined in Mass. R. Crim. P. 36(b)(2). Bail and the Dangerousness Hearing in Massachusetts covers the qualifying offenses, the evidence, and the conditions a judge may impose.

Discovery

Discovery in a Massachusetts criminal case is largely automatic. Mass. R. Crim. P. 14, as amended effective March 1, 2025, requires the prosecution to disclose a defined list of material without any motion.

The list covers the written or recorded statements of the defendant and any co-defendant; grand jury minutes and witness statements; prospective witness identities and statements; police and investigator reports; photographs, recordings, tangible objects, and intended exhibits; physical examinations and scientific tests; expert information; and summaries of identification procedures. Separate rules govern the authentication and admissibility of text messages, phone contents, social-media material, and other digital evidence.

Rule 14 separately requires disclosure of material that tends to cast doubt on guilt, on the credibility of the evidence, or on the credibility of a witness. It also requires disclosure of any promise, reward, or inducement sought by, offered to, or given to a witness.

Rule 14.1 governs reciprocal discovery from the defense, Rule 14.2 governs discovery procedures and enforcement, and Rule 14.3 governs notice of self-defense and first-aggressor evidence. A party may seek records held by a third party through a summons under Mass. R. Crim. P. 17, subject to the rule’s requirements and any applicable privilege or protective procedure. When surveillance video may matter, counsel should seek preservation and production before the retention period expires. The defense must also identify missing automatic discovery and ask the court to enforce the Commonwealth’s obligations when necessary.

Pretrial Motions

A motion to dismiss challenges the complaint or the indictment before trial. In the District Court and the Boston Municipal Court, the ground is most often that the application did not establish probable cause within its four corners. In the Superior Court, an indictment is subject to dismissal where the grand jury heard insufficient evidence or where the integrity of the proceeding was impaired. Dismissal motions also cover lost and destroyed evidence and defective complaints.

Motor vehicle cases carry a further ground. Failure to give the violator a copy of the citation at the time and place of the violation is a defense. M.G.L. c. 90C, § 2. The statute lists three exceptions. The first is where the violator could not have been stopped. The second is where additional time was reasonably necessary to determine the nature of the violation or the identity of the violator. The third is where the court finds a circumstance that justifies the failure. How Massachusetts criminal cases get dismissed sets out each ground, and the difference between dismissal with prejudice, dismissal without prejudice, and a nolle prosequi.

A motion to suppress asks the court to exclude evidence obtained in violation of the Fourth Amendment, Article 14, the Fifth Amendment, or Article 12. Massachusetts law provides greater protection than federal law at some stages of a police encounter, and an exit order and a patfrisk each require separate justification. When the challenged evidence is central to the prosecution, the ruling can determine whether the case continues. Illegal searches and seizures in Massachusetts explains the governing rules.

Mass. R. Crim. P. 36 sets the time within which a case must be tried and defines the periods excluded from that computation. A case not tried within the time the rule allows may be dismissed on motion.

Pleas, Diversion, and Other Dispositions

Most Massachusetts criminal cases resolve without a verdict. The available outcomes run from dismissal through pretrial probation under M.G.L. c. 276, § 87, which requires no admission, statutory diversion, a continuance without a finding, a plea with an agreed recommendation, and a plea with the disposition contested before the judge. A defendant who cannot agree with the Commonwealth may tender a plea together with a request for a specific disposition. The court must permit withdrawal of the plea if it intends to exceed the requested terms. M.G.L. c. 278, § 18.

Statutory diversion is decided at arraignment. The court continues the case fourteen days for assessment, or thirty days for a veteran or a person on active service. It may then stay the proceedings for ninety days on the defendant’s written consent and a knowing waiver of the right to a speedy trial. M.G.L. c. 276A, §§ 2, 3, and 5. Statements made during the assessment, or in fulfilling the terms of the stay, are not admissible and are not disclosed to a prosecutor. The statute sets no age limit.

Before accepting a plea of guilty, a plea of nolo contendere, or an admission to sufficient facts, the court must give the immigration advisement prescribed by M.G.L. c. 278, § 29D, and must give it at every plea colloquy. Absent a record that the advisement was given, the defendant is presumed not to have received it.

Each disposition carries different consequences for the record, for sealing eligibility, for immigration status, for professional licensing, and for firearms rights. A disposition that suits one defendant is disqualifying for another. Pretrial Probation, CWOFs, and Diversion in Massachusetts compares them.

Trial

At trial the Commonwealth must prove every element of every charge beyond a reasonable doubt, and a jury verdict must be unanimous. Trial in the District Court and the Boston Municipal Court is by a jury of six. A case in the Boston Municipal Court moves through these same stages in its own eight divisions. The alternative is a written waiver and consent to be tried by the court. M.G.L. c. 218, § 26A. Superior Court criminal juries are twelve.

If a juror’s ability to continue becomes disputed after deliberations begin, the judge must use a separate procedure. The firm’s analysis of the Lindsay Clancy juror dispute addresses the required inquiry and the limited authority to substitute an alternate.

The waiver decision cannot be taken until the pretrial conference has been held and the results of that conference have been heard. Pretrial discovery motions must also have been disposed of and complied with. That is why the discovery stage governs the timing of the trial election. The stages of the trial itself, and the evidence rules that govern them, are covered in the Massachusetts criminal court practice section.

The defendant has the right to confront and cross-examine the Commonwealth’s witnesses, to present evidence or none, and not to testify. No inference may be drawn from a decision not to testify. Jury selection is the first contested stage of the trial itself. At the close of the Commonwealth’s case the defense moves for a required finding of not guilty. Whether an objection was preserved at trial governs the standard applied on appeal. Representative outcomes are collected at Massachusetts Criminal Defense Results.

Sentencing

A District Court or Boston Municipal Court committed sentence runs to the house of correction. Only the Superior Court may impose a state prison sentence. A judge may impose a committed sentence, a suspended sentence with probation, straight probation, or a fine. The court may also continue a case without a finding after an admission to sufficient facts. The same hearing may address restitution, statutory assessments, credit for time served, and whether sentences run concurrently or consecutively. Sentencing in the Massachusetts District Court and BMC explains these dispositions and the revocation exposure that can follow probation.

Probation and the Surrender Hearing

A disposition that includes probation, including a continuance without a finding, keeps the case open until the term ends. A probation violation is adjudicated at a surrender hearing. The standard is a preponderance of the evidence. Commonwealth v. Holmgren, 421 Mass. 224 (1995). Reliable hearsay is admissible, and a violated continuance without a finding can be converted to a guilty finding with a sentence imposed on the original charge. Massachusetts Probation Violation Defense covers how the proceeding begins, what evidence is permitted, and what the judge may do.

Appeal and Postconviction Review

A conviction after trial may be appealed. A disposition may also be revised or revoked on a motion filed within sixty days of the disposition, and that sixty-day period is jurisdictional. Mass. R. Crim. P. 29. A motion for a new trial may be filed at any time under Mass. R. Crim. P. 30(b), where it appears that justice may not have been done. Rule 30(a) is available to a person imprisoned or otherwise restrained on a criminal conviction. The ground is that the confinement or restraint was imposed in violation of the Constitution or laws of the United States or of the Commonwealth.

A separate statute provides access to forensic and scientific analysis after conviction. In Commonwealth v. Watson, SJC-13850 (July 9, 2026), the Supreme Judicial Court held that M.G.L. c. 278A permits postconviction digital forensic analysis of a cell phone. Correcting a Massachusetts Criminal Sentence covers Rule 29 and Rule 30 practice, and the decision and its uses are examined in the firm’s post on Commonwealth v. Watson and postconviction digital forensic analysis.

The Criminal Record and Its Consequences

A case that has ended still has effects. Sealing under M.G.L. c. 276, § 100A becomes available three years after a misdemeanor disposition and seven years after a felony disposition. The period is measured from the court appearance and disposition records, and it includes any period of incarceration or custody.

Sealing after a case ends without a conviction has no waiting period. On a finding of not guilty, a no bill, or a finding of no probable cause, the commissioner seals the record unless the defendant objects in writing. M.G.L. c. 276, § 100C. On a nolle prosequi or a dismissal entered by the court, the court directs sealing where substantial justice would best be served, which requires the petitioner to establish good cause. Commonwealth v. Pon, 469 Mass. 296 (2014).

Immigration, professional-licensing, firearms, and academic consequences follow separate rules. Depending on the rule, the charge, alleged conduct, admission, or final disposition may matter. Who can see a Massachusetts criminal record explains the levels of access. Sealing and expunging a Massachusetts criminal record explains the available procedures. Immigration consequences of Massachusetts criminal charges explains the federal treatment of a continuance without a finding and an admission to sufficient facts.

Chapter 163 and Noncitizen Defendants

Chapter 163 of the Acts of 2026 added five rules that run alongside the ordinary stages of a Massachusetts criminal case when the defendant is a noncitizen.

1. Questions about status. M.G.L. c. 147, § 64 provides that immigration or citizenship status is directly material only when it is necessary to establish an element of a Massachusetts criminal offense. Status is not directly material to credibility, to cooperation, or to general information gathering.
2. Civil arrests at the courthouse. M.G.L. c. 221D prohibits a civil arrest inside a Massachusetts courtroom. Anywhere else in the courthouse or on its grounds, an officer may make one only after showing a judicial warrant or order to a judge sitting in that courthouse for prompt review. An ICE administrative warrant, removal warrant, notice to appear, or civil detainer is not a judicial warrant.
3. A final order of removal at bail. M.G.L. c. 276, § 58 allows a judge to consider a final removal order, meaning a final order of deportation, as a factor in assessing risk of flight when setting bail. Every statutory condition must be met first, including that the alleged acts involve a felony under Massachusetts law. Immigration status alone, a detainer, or a pending immigration case does not satisfy that language.
4. Notice of counsel at intake. M.G.L. c. 127, § 87B requires state and county correctional facilities, houses of correction, and prerelease centers holding detained people to give each person written notice at intake, in that person’s primary language, of the right to counsel and the right to decline interviews by state or federal law enforcement and consular officials. Courthouses are excluded.
5. T and U visa certifications. M.G.L. c. 258F requires a Massachusetts district attorney’s office, police department, or other certifying entity to decide a crime victim’s certification request within 45 days, or within 14 business days when the applicant is in removal proceedings or faces an immigration hearing or an aging-out beneficiary within 45 days. The entity cannot require that charges were filed or that anyone was convicted.
