Yes — but only under specific circumstances, and the prosecution has to earn it. If you’re reading this from a jail cell or a family member just called you from one, here is what you need to know.
This guide explains the dangerousness hearing process: what it is, how it works, which charges trigger it, and why the next 48 to 72 hours are the most important in your case, especially on sex offense charges.
What Is a Dangerousness Hearing?
A dangerousness hearing is a formal legal proceeding under Massachusetts General Laws Chapter 276, § 58A. It allows the Commonwealth — the prosecution — to ask a judge to hold you in jail without any bail at all, before you have been convicted of anything, if the prosecution can show that you pose a danger to others and that no conditions of release would adequately protect the community.
Pretrial detention is supposed to be a last resort. Massachusetts law presumes that people who have been charged with crimes — but not convicted — are entitled to their liberty. The system is built around the idea that bail exists to ensure you come back to court, not to punish you in advance. But § 58A creates a limited exception to that principle.
How It Starts: The Commonwealth's Motion at Arraignment
The process begins the moment you walk into court for your arraignment — your first formal court appearance. If the prosecution wants to hold you without bail under § 58A, they must make that request right then and there. They can’t wait.
When the Commonwealth makes the motion, the judge decides whether to hold you briefly while the dangerousness hearing is scheduled. You do not go home that day.
The Preliminary Hearing: 3 to 7 Days
The full dangerousness hearing must take place quickly. Under § 58A, if the Commonwealth requests a continuance, it gets at most three days. If you or your attorney requests more time — which is often strategically wise — you can get up to seven days.
That short window is one of many reasons why getting a lawyer the same day as your arraignment is critical.
At the hearing itself, you have real rights:
- The right to an attorney (and to have one appointed if you can’t afford one)
- The right to testify on your own behalf
- The right to present witnesses and other evidence
- The right to cross-examine witnesses the prosecution calls
The hearing is not a trial. The rules of evidence are relaxed. The prosecution can present hearsay, police reports, and other materials that would not be admissible at trial. That makes it even more important to have an experienced criminal defense attorney who knows how to challenge the Commonwealth’s evidence in this unusual setting.
The Standard: Clear and Convincing Evidence
To hold you without bail, the prosecution must prove by clear and convincing evidence that you pose a danger to another person or to the community, and that no combination of conditions — GPS monitoring, house arrest, a restraining order, electronic monitoring — would adequately protect the public.
That is a substantial burden. “Clear and convincing” is a higher standard than “probable cause,” though lower than “beyond a reasonable doubt.” The Commonwealth must do more than point to the seriousness of the charges. It must show that you, specifically, present an ongoing and unmanageable risk.
A skilled attorney can challenge whether the prosecution has truly met that burden, present mitigating information about your life and circumstances, and argue for conditions that would adequately protect anyone at risk while allowing you to go home.
How Long Can You Be Held?
If a judge finds dangerousness by clear and convincing evidence, you can be detained without bail pending trial. The statute requires that you be brought to trial as soon as reasonably possible. At the 90-day mark, you have the right to request a new hearing to revisit the detention order.
In practice, sex offense cases in Superior Court are complex. They involve extensive discovery, expert witnesses, and pretrial motions that take time to litigate. Even with everyone moving as efficiently as possible, pretrial detention in these cases can stretch to four, five, or six months or longer — particularly if either side needs time to prepare properly. That is real time away from your job, your family, and your life, before any verdict has been reached.
Which Sex Offenses Qualify for a Dangerousness Hearing?
Not every sex offense charge entitles the Commonwealth to seek your pretrial detention. This is one of the most important — and often misunderstood — aspects of the law.
Under § 58A, a defendant can only be held without bail if charged with a predicate offense. For sex crimes, the key question is whether the charged offense, as a matter of law, requires physical force as an element of the crime.
The Massachusetts Supreme Judicial Court uses what is called a “categorical approach“: courts look at the legal elements of the offense itself, not the specific facts of what allegedly happened. If the statute can be violated without physical force, the offense does not qualify — regardless of how the alleged conduct is described.
Two landmark cases establish this principle in the sex offense context:
Commonwealth v. Barnes, 481 Mass. 225 (2019)
The SJC held that statutory rape of a child (G.L. c. 265, § 23A) is not a predicate offense under § 58A.
The reason: statutory rape can be proven entirely through the age of the victim, with no requirement of physical force. Because force is not an element of the offense as a matter of law, a person charged with statutory rape cannot be held without conditions of release on dangerousness grounds.
Commonwealth v. Vieira, 483 Mass. 417 (2019)
The SJC extended that logic to indecent assault and battery on a child under 14 (G.L. c. 265, § 13B). Even though this offense involves physical contact, the SJC held that “touching” is not the same as “force” — the degree of contact required to commit indecent A&B does not satisfy the force clause of § 58A. Someone charged only with § 13B cannot be detained without bail on dangerousness grounds.
The principle underlying both cases is straightforward: the legislature specifically limited pretrial detention to the most serious offenses involving actual physical force. Sex offenses that can be committed without violence — even very serious ones — fall outside that category.
Even If § 58A Doesn't Apply, You're Not Automatically Free
Here is something that surprises many people: even if the prosecution cannot hold you under § 58A — either because your charge doesn’t qualify or because they lost the hearing — that does not mean you will be released on low bail or released at all.
Under the ordinary bail statute, G.L. c. 276, § 58, a judge sets bail to ensure that you will return to court. Bail is not supposed to be based on dangerousness when § 58A is not in play. But judges have broad discretion in setting the amount, and in sex offense cases — especially those involving children or allegations of serious violence — bail amounts can reach six figures. In some cases, bail is set so high that it functions as de facto detention.
Courts also routinely impose significant conditions of release in sex offense cases, even when dangerousness detention is not ordered. These can include:
- Electronic monitoring (GPS)
- No contact with the alleged victim or witnesses
- Exclusion zones prohibiting you from being near certain locations
- Restrictions on your internet access or use of electronic devices
- Check-ins with probation or pretrial services
GPS monitoring as a pretrial condition is constitutionally complex — the SJC has recognized significant limits on when it is appropriate — but courts continue to impose it, and fighting improper conditions requires an attorney who knows the case law.
Bail Review in Superior Court
If you believe your bail is excessive or that conditions of release were wrongly imposed, you are not stuck with the initial ruling. You have the right to seek a bail review in Superior Court under G.L. c. 276, § 58. A Superior Court judge can lower bail, modify conditions, or release you on new terms.
Bail review is a powerful tool that is frequently underused. In sex offense cases where bail has been set at a level designed to keep you in custody, an experienced attorney can present a more complete picture — your ties to the community, your employment, your family, the weaknesses in the prosecution’s case — and make a compelling argument for release on reasonable terms.
Why Having an Attorney at Arraignment Changes Everything
The hours between your arrest and your arraignment are the most consequential period of your entire case.
Arraignment is where the prosecution moves for a dangerousness hearing. It is where bail is set or denied. It is where conditions of release are imposed. If you walk into that courtroom without an attorney who has had a chance to review your charges, prepare an argument, and anticipate the prosecution’s moves, you are at a significant disadvantage from the moment the hearing begins.
An attorney retained before arraignment can:
- Immediately challenge whether your charge qualifies as a § 58A predicate at all
- Prepare mitigation material — letters, employment records, family circumstances — to present to the judge
- Make a compelling bail argument under § 58 even if § 58A does apply
- Request the maximum continuance to prepare for the full dangerousness hearing
- Begin investigating the prosecution’s evidence before it is used against you
- Seek bail review in Superior Court if the initial outcome is unfavorable
