Sexual Assault and Rape Defense in Massachusetts

Massachusetts prosecutes rape, indecent assault and battery, child pornography, photographing an unsuspecting person, and related sex offenses under separate statutes with different elements and penalties. The exact section controls whether the Commonwealth must prove force or lack of consent, whether age eliminates consent as a defense, whether the court may enter a continuance without a finding, and what sentence the court may impose. A defense lawyer should identify the charged section and the evidence required to prove it before discussing a disposition.

The consequences do not share a single trigger. Arraignment creates a CORI entry. A conviction or adjudication for an offense listed in M.G.L. c. 6, § 178C can require Sex Offender Registry Board classification and registration. A judge may impose global positioning system monitoring during probation only after the individualized hearing Massachusetts law requires. Immigration, professional licensing, and campus proceedings apply their own rules. This page explains the charged offenses, sentencing ranges, pretrial procedure, evidentiary rules, trial preparation, and consequences beyond the criminal case.

The Offenses Charged in Massachusetts Sex Cases

Rape and Aggravated Rape, M.G.L. c. 265, § 22

Section 22(b) is the base offense. It punishes sexual intercourse or unnatural sexual intercourse where the defendant compels the complainant to submit by force and against their will, or by threat of bodily injury. The penalty is up to twenty years in state prison. A second or subsequent offense is punishable by life or any term of years.

Section 22(a) is aggravated rape. It requires the same conduct plus one of three circumstances: the act results in or is committed with acts resulting in serious bodily injury, the act is committed by a joint enterprise, or the act is committed during the commission or attempted commission of one of the offenses the section enumerates. Those offenses are assault and battery with a dangerous weapon and assault with a dangerous weapon under M.G.L. c. 265, §§ 15A and 15B, armed robbery under § 17, unarmed robbery under § 19, kidnapping under § 26, the burglary and breaking and entering offenses in M.G.L. c. 266, §§ 14 to 18, and carrying a dangerous weapon under M.G.L. c. 269, § 10. The penalty is life or any term of years.

Section 22(a) carries no mandatory minimum. The only ten-year floor in § 22 applies when a person commits an offense described in the section while armed with a firearm as defined in M.G.L. c. 140, § 121. A second or subsequent armed offense is punishable by life or any term of years but not less than fifteen. A person serving a sentence for a second or subsequent offense is ineligible for furlough, temporary release, or outside education, training, or employment programs until two thirds of the minimum has been served.

Section 22(c) supplies a third theory. A law enforcement officer who has sexual intercourse with a person in the officer’s custody or control is in violation of subsection (b), and in a prosecution under that subsection the person is deemed incapable of consent to sexual intercourse with the officer. The subsection defines sexual intercourse broadly and defines law enforcement officer to include police officers, campus police officers holding special state police authority, correction officers, court officers, probation and parole officers, and others.

Rape of a Child With Force, M.G.L. c. 265, §§ 22A, 22B and 22C

These three sections punish the same conduct at different sentencing levels. Each requires sexual intercourse or unnatural sexual intercourse with a child under sixteen, compelled by force and against the child’s will or by threat of bodily injury. Aggravating circumstances and qualifying prior convictions determine which section applies.

• Section 22A punishes rape of a child with force by life or any term of years, without a minimum term. A prosecution under this section may not be continued without a finding or placed on file.
• Section 22B punishes aggravated rape of a child with force by life or any term of years, but not less than fifteen years. The section applies when the offense occurs during an enumerated felony, results in substantial bodily injury as defined in M.G.L. c. 265, § 13J, occurs while the victim is tied, bound, or gagged, follows the administration of alcohol or a controlled substance without consent, is committed by a joint enterprise, or is committed in a manner that could transmit a sexually transmitted disease or infection of which the defendant knew or should have known they were a carrier.
• Section 22C punishes rape of a child with force by a previously convicted offender by life or any term of years, but not less than twenty years. The predicate list includes §§ 13B, 13B1/2, 13H, 24B, 22A, 22B, 23, 23A, and 22, along with like violations in another jurisdiction.

Under § 22C, the Commonwealth may prove the prior conviction through certified attested copies of court papers or probation or correction records. The statute makes those records prima facie evidence, self-authenticating, and admissible after the Commonwealth establishes guilt on the primary offense. The statutory method does not require a live witness to authenticate the records. When the defendant contests the qualifying conviction or identity, counsel should examine the complete record of the earlier case.

Rape and Abuse of a Child, M.G.L. c. 265, §§ 23, 23A and 23B

This is the group commonly called statutory rape. Force is not an element. Section 23 punishes whoever unlawfully has sexual intercourse or unnatural sexual intercourse, and abuses, a child under sixteen. The penalty is life, any term of years, or any term in a jail or house of correction. A prosecution under the section shall neither be continued without a finding nor placed on file.

The Commonwealth must prove two elements. Commonwealth v. Miller, 385 Mass. 521, 522 (1982), states them: “(1) sexual intercourse or unnatural sexual intercourse, with (2) a child under sixteen years of age.” Abuse is not a separate element. It is implied as a matter of law from intercourse with a child under sixteen.

• Section 23A punishes aggravated rape and abuse of a child by life or any term of years, but not less than ten years. It applies when the age difference exceeds five years and the child is under twelve, when the age difference exceeds ten years and the child is between twelve and sixteen, or when the defendant was a mandated reporter as defined in M.G.L. c. 119, § 21.
• Section 23B punishes rape and abuse of a child by a previously convicted offender by life or any term of years, but not less than fifteen years. It uses the same predicate-offense list as § 22C.

Because § 23 has no minimum and permits a house of correction sentence, a charge under § 23A materially changes the possible sentence. Counsel should calculate the age difference from the actual birth dates and determine the defendant’s mandated-reporter status from the governing definition rather than rely on a police report’s characterization.

Indecent Assault and Battery, M.G.L. c. 265, §§ 13B, 13B1/2, 13B3/4, 13F, 13H, 13H1/2 and 13H3/4

• Section 13B punishes indecent assault and battery on a child under fourteen by up to ten years in state prison or up to two and one half years in a house of correction. It states no minimum term, bars both a continuance without a finding and placement on file, and deems the child incapable of consenting.
• Section 13B1/2 punishes aggravated indecent assault and battery on a child under fourteen by life or any term of years, but not less than ten years, when the offense occurs during an enumerated felony or the defendant was a mandated reporter. The section imposes a mandatory minimum and bars both a continuance without a finding and placement on file.
• Section 13B3/4 punishes indecent assault and battery on a child under fourteen by a previously convicted offender by life or any term of years, but not less than fifteen years. The section imposes a mandatory minimum, bars both a continuance without a finding and placement on file, and uses the same certified-record method of proving the prior conviction as § 22C.
• Section 13F punishes indecent assault and battery on a person whom the defendant knows to have an intellectual disability. It is punishable by five to ten years in state prison on a first offense and not less than ten years on a second or subsequent offense. The statute expressly excepts a first offense from the bar on suspension, probation, and parole, so the five-year figure governs a committed sentence rather than time that must be served. The section does not apply when one person with an intellectual disability commits the offense against another.
• Section 13H punishes indecent assault and battery on a person who has attained age fourteen by up to five years in state prison or up to two and one half years in a jail or house of correction. It states no minimum term. When the complainant is an elder or a person with a disability as defined in M.G.L. c. 265, § 13K, the maximum rises to ten years, and a second or subsequent offense carries up to twenty years. Only that paragraph bars both a continuance without a finding and placement on file.
• Section 13H1/2 punishes indecent assault and battery by a law enforcement officer on a person in the officer’s custody or control. The maximum depends on the person’s circumstances: up to five years in state prison for a person who has attained age fourteen, up to ten years for an elder or a person with a disability as defined in § 13K, five to ten years on a first offense when the officer knows the person has an intellectual disability, and up to ten years when the person is a child under fourteen. The last subsection bars both a continuance without a finding and placement on file. The statute deems the person incapable of consenting to sexual contact with the officer.
• Section 13H3/4 punishes indecent assault and battery on a patient or client by a health care provider or clergy member during diagnosis, counseling, or treatment. It is punishable by up to five years in state prison or up to two and one half years in a house of correction. The statute defines health care provider by license category and deems the patient or client incapable of consenting when a false representation that the contact served a legitimate medical, counseling, or treatment purpose procured the consent.

The bar on a continuance without a finding in § 13H applies only to the elder and person with a disability paragraph. An ordinary § 13H charge involving a complainant fourteen or older is not barred by the statute from that disposition.

Assault With Intent to Commit Rape, M.G.L. c. 265, §§ 24 and 24B

Section 24 punishes assault with intent to commit rape by up to twenty years in state prison or up to two and one half years in a jail or house of correction. A second or subsequent offense is punishable by life or any term of years. Committing the offense while armed with a firearm carries not less than five years, and a second or subsequent armed offense is punishable by life or any term of years, but not less than twenty years. Section 24B covers assault of a child under sixteen with intent to commit rape and is punishable by life or any term of years, with a five-year floor for a subsequent offense by a person over eighteen, a ten-year floor when the defendant is armed with a firearm, and a fifteen-year floor for a second or subsequent armed offense by a person over eighteen.

Neither section bars a continuance without a finding, and neither contains the language that makes a floor into time that must be served. The only collateral restriction in § 24 covers furlough, temporary release, and outside programs, and only until two thirds of the minimum has been served.

Child Pornography, M.G.L. c. 272, §§ 29A, 29B and 29C

Sections 29A, 29B, and 29C define three separate offenses with materially different penalties.

• Section 29C punishes knowing purchase or possession by up to five years in state prison, up to two and one half years in a jail or house of correction, a fine of $1,000 to $10,000, or both fine and imprisonment. A second offense carries not less than five years, a fine of $5,000 to $20,000, or both. A third or subsequent offense carries not less than ten years, a fine of $10,000 to $30,000, or both. Section 29C alone among the three bars both a continuance without a finding and placement on file.
• Section 29B punishes dissemination or possession with intent to disseminate by ten to twenty years in state prison, a fine of $10,000 to $50,000 or three times any economic gain, whichever is greater, or both.
• Section 29A punishes hiring, employing, procuring, or knowingly permitting a child to pose or be exhibited in a state of nudity or to engage in sexual conduct for visual material. It is punishable by ten to twenty years in state prison, a fine of $10,000 to $50,000, or both. Lascivious intent is an element of subsection (a), but not subsection (b), which covers sexual conduct and live performances.

Knowing possession under § 29C is punishable by up to five years in state prison. Possession with intent to disseminate under § 29B is punishable by a state prison term of ten to twenty years. The difference turns on proof of intent. In a case built on a forensic image of a hard drive, the Commonwealth may rely on file-sharing software, folder structure, or messages to prove that intent. In Attorney Joe Serpa’s experience, whether the Commonwealth can prove intent to disseminate is often the central contested question in these cases.

Juvenile Sexting, M.G.L. c. 272, § 29D

Section 7 of Chapter 118 of the Acts of 2024, An Act to Prevent Abuse and Exploitation, inserted § 29D for people under the age of criminal majority who possess, purchase, or disseminate this material. The Juvenile Court has exclusive jurisdiction. An adjudication under § 29D does not require Sex Offender Registry Board registration, does not result in transmission of data to the Board, and is not subject to the exclusions in M.G.L. c. 276, § 100J. The records are eligible for expungement. The section also excludes from dissemination a report to law enforcement, the Department of Elementary and Secondary Education, or a parent, foster parent, guardian, teacher, principal, or other relevant school official.

Subsection (e) supplies affirmative defenses to any crime alleged to have been committed by a juvenile under § 29A, § 29B, § 29C, or § 29D. The first applies when the material portrays no person other than the juvenile. The second applies when the juvenile was under eighteen, the material portrays only a person sixteen or older, the person in the image knowingly and voluntarily created and provided it to the juvenile, and the juvenile did not make the material available to anyone other than the depicted person who sent it. An adjudication under § 29D carries no registration obligation and is eligible for expungement. A conviction under § 29B or § 29C requires registration and creates a criminal record. The charged section therefore controls both consequences.

Photographing an Unsuspecting Person, M.G.L. c. 272, § 105

Subsection (b) contains three offenses with different elements and penalties.

• The first paragraph punishes willfully photographing, videotaping, or electronically surveilling a nude or partially nude person, with intent to conduct or conceal the activity secretly, when the person has a reasonable expectation of privacy and has not consented. It is punishable by up to two and one half years in a house of correction, a fine up to $5,000, or both, and has no age element.
• The second paragraph applies the same penalty to the same conduct directed at a person’s intimate parts under or around clothing. It also has no age element.
• The third paragraph punishes the under-clothing or around-clothing offense when the person is a child under eighteen. It is punishable by up to two and one half years in a house of correction, up to five years in state prison, a fine up to $10,000, or both.

The five-year state prison exposure applies to the third, clothing-based offense, not to the offense involving a nude or partially nude person. The word “nude” does not appear in the third paragraph. Secretly photographing a nude minor falls under the first paragraph, which carries the same house of correction exposure as the offense involving an adult complainant. Subsection (c) separately punishes dissemination by up to five years in state prison for images taken under the first two paragraphs and up to ten years for an image of a child taken under the third.

Section 105 contains no subsequent-offense enhancement. It also does not appear among the offenses listed in M.G.L. c. 6, § 178C, so a § 105 conviction does not require sex offender registration.

In Commonwealth v. Robertson, 467 Mass. 371 (2014), the Supreme Judicial Court held that the version of § 105 then in effect did not apply to photographing a fully clothed person. The Legislature later added the paragraphs covering images taken under or around clothing. Material written before that amendment does not describe the current statute.

Digitized and Artificially Generated Sexual Images, M.G.L. c. 265, § 43A(b)

M.G.L. c. 265, § 43A(b), rather than chapter 272, covers artificially generated and digitally altered sexual images. Section 6 of Chapter 118 of the Acts of 2024 replaced the former subsection (b) of the criminal-harassment statute and added subsection (c). Section 43A(b) defines digitization as creating or altering visual material so that it would falsely appear to a reasonable person to be an authentic representation of the depicted person. The offense requires knowing distribution of the material, an identifiable depicted person, physical or economic injury or substantial emotional distress, and either intent to harm or reckless disregard of the likelihood of harm, lack of consent, and reasonable expectation of privacy.

A first offense is punishable by up to two and one half years in a house of correction, a fine up to $10,000, or both. Under subsection (c), a second or subsequent offense under § 43A, or an offense committed after a conviction under M.G.L. c. 265, § 43, is punishable by up to two and one half years in a house of correction or up to ten years in state prison, a fine up to $15,000, or both.

Consent to create the material does not constitute consent to distribute it. Subsection (b) excludes specified categories, including voluntary or consensual nudity or sexual conduct in a commercial setting or without a reasonable expectation of privacy, distribution in the public interest, certain lawful practices of law enforcement and other institutions, matters of public concern, and certain content provided through computer or telecommunications services by another person. The page on deepfake and AI-generated intimate image charges addresses the statutory exclusions, federal law, and available defenses in detail.

Sentencing Exposure and the Dispositions the Statutes Foreclose

Three statutory questions define the dispositions and sentences available for each charge.

The first is whether the section states a minimum term at all. Sections 22(a), 22A, 23, 13B and 13H state none. Sections 22B, 22C, 23A, 23B, 13B1/2 and 13B3/4 do.

The second is whether that minimum is a term that must be served. Sections 22B, 22C, 23A, 23B, 13B1/2 and 13B3/4 each provide that the sentence shall not be reduced below the minimum, shall not be suspended, and that the person is ineligible for probation, parole, work release or furlough, or any deduction for good conduct, until the minimum has been served. That combination is what makes those figures true mandatory minimums. Section 13F contains the same language but expressly excepts a first offense from it. Sections 24 and 24B state floors without any of it.

The third is whether the section forecloses a disposition. Sections 22A, 22B, 22C, 23, 23A, 23B, 13B, 13B1/2, and 13B3/4 of chapter 265, the elder and person with a disability paragraph of § 13H, subsection (e) of § 13H1/2, and § 29C of chapter 272 each provide that a prosecution shall neither be continued without a finding nor placed on file. Counsel must identify those restrictions before proposing a disposition that the court has no power to accept.

Sections 29A and 29B state the prison term in the alternative with a fine. Neither section bars suspension of the sentence or makes the defendant ineligible for probation, parole, furlough, work release, or good-conduct deductions. Under Commonwealth v. Lightfoot, 391 Mass. 718, 721 (1984), that additional language makes a statutory floor a term that must be served, and it is absent here. Under Commonwealth v. Brown, 431 Mass. 772 (2000), a “not less than” figure is “always the shortest sentence that can be imposed, the number of years that determines parole eligibility.” A state prison sentence under § 29A or § 29B therefore cannot carry a minimum below ten years, but the statutes also authorize a fine in the alternative. No Massachusetts appellate decision describes the ten-year term in § 29A or § 29B as a mandatory minimum.

Consent, Age, and Force

The charged statute determines whether consent and force are elements and whether the defense may contest them.

Consent is a live question under M.G.L. c. 265, § 22 and no question at all under § 23. Commonwealth v. Wilbur W., 479 Mass. 397, 398 to 399 (2018), holds that statutory rape is a strict liability offense, that a person below sixteen is deemed incapable of consenting to sexual intercourse, and that lack of consent is therefore not an element and the intent of the accused is not relevant. Reasonable mistake as to age is not a defense. Massachusetts has no close-in-age exception. The same incapacity appears by statute in §§ 13B and 13B1/2 for a child under fourteen, in §§ 22(c) and 13H1/2 for a person in the custody or control of a law enforcement officer, and in § 13H3/4 where consent was procured by a false representation of a legitimate treatment purpose.

Force is an element under §§ 22, 22A, 22B, and 22C, but not under § 23 or § 23A. In Scione v. Commonwealth, 481 Mass. 225 (2019), the Supreme Judicial Court held that § 23A does not require the use, attempted use, or threatened use of physical force. The Court cited Commonwealth v. Bernardo B., 453 Mass. 158, 172 (2009), for the same distinction. Counsel must direct any challenge to force at a charge for which force is an element.

Under § 22, the Commonwealth must prove both that the act occurred and that force or a threat of bodily injury compelled the complainant to submit. Attorney Serpa has found that proof of compulsion is often the more contested element. When the parties knew each other, messages before and after the encounter may provide important evidence that the police did not collect.

Time Limits on Prosecution Under M.G.L. c. 277, § 63

For most sex offenses involving a child, there is no limitations period. An indictment or complaint for an offense set forth in M.G.L. c. 265, §§ 13B, 13B1/2, 13B3/4, 13F, 13L, 22A, 22B, 22C, 22D, 23, 23A, 23B or 24B, or § 50(b), may be found and filed at any time after the date of the offense. Conspiracy to commit any of them and accessory liability for any of them are covered on the same terms.

An indictment or complaint filed more than twenty-seven years after the alleged offense must have independent evidence corroborating the complainant’s allegation. The corroborating evidence is admissible at trial and may not consist exclusively of mental-health professionals’ opinions.

Not every sex offense is in the unlimited group. An indictment for an offense under M.G.L. c. 265, § 22, § 24, or § 50(a) must be found and filed within fifteen years after the offense. For a sex offense that does not appear in a longer limitations-period list, § 63 applies a six-year residual period. That residual period includes § 13H and the chapter 272 offenses discussed on this page.

Two rules can extend these periods. When the complainant was under sixteen at the time of an offense specified in M.G.L. c. 277, § 63, including the listed chapter 265 offenses and chapter 272, §§ 29A and 29B, the limitation period does not begin until the complainant turns sixteen or someone reports the alleged offense to a law enforcement agency, whichever occurs earlier. The calculation also excludes any period during which the defendant was not usually and publicly a resident of Massachusetts.

Pretrial Procedure in a Massachusetts Sex Offense Case

The page on the Massachusetts criminal process explains the general sequence from a complaint application through trial. A sex offense charge requires particular attention to the complaint stage, arraignment, and possible pretrial detention.

The Clerk-Magistrate Hearing and Arraignment

When an eligible case begins with an application for a complaint rather than an arrest, the court may schedule a private clerk-magistrate hearing. If the clerk-magistrate denies the application, no complaint issues, no arraignment occurs, and the application creates no CORI entry. The denial does not erase a police report, and it is not technically a final judgment, although it ends nearly every ordinary application that the clerk-magistrate denies. Attorney Serpa prepares from the complete available record and conducts the hearing according to the testimony and questions that develop rather than from a fixed script.

When a case begins with an arrest, arraignment creates a CORI entry even if the charge is later dismissed. Depending on the disposition and offense, sealing or expungement may later restrict access to or erase an eligible Massachusetts record. A sex offense that exceeds the District Court’s or Boston Municipal Court’s final jurisdiction proceeds in the Superior Court after indictment.

Dangerousness and Pretrial Detention Under M.G.L. c. 276, § 58A

The Commonwealth frequently moves at arraignment for pretrial detention or release on conditions under M.G.L. c. 276, § 58A. A judge may order detention only after finding by clear and convincing evidence that no release conditions will reasonably assure the safety of another person or the community. Absent good cause, detention is capped at 120 days in the District Court and 180 days in the Superior Court. The rules of evidence for criminal trials do not apply, and the judge must consider hearsay in a police report or in an alleged victim’s or witness’s statement. The practitioner’s guide to bail and dangerousness hearings explains the procedure in detail.

The judge must first determine whether the charged offense qualifies as a § 58A predicate. Scione v. Commonwealth, 481 Mass. 225 (2019), holds that M.G.L. c. 265, § 22A qualifies under the force clause because compelling a child to submit by force or threat of bodily injury is an element. Section 23A does not qualify under that clause because force is not an element. The Court also held the residual clause, which covered any other felony that by its nature involved a substantial risk of physical force, unconstitutionally vague under article 12 of the Massachusetts Declaration of Rights. The judge applies a categorical approach based on the statutory elements rather than the alleged facts.

The Evidentiary Rulings That Shape the Trial

In Attorney Serpa’s experience, a small number of evidentiary rulings made before trial often define the evidence the jury will hear.

The First Complaint Doctrine

Commonwealth v. King, 445 Mass. 217 (2005), replaced the former fresh-complaint practice. A single witness, ordinarily the person the complainant first told, may testify to the fact of the complaint, the circumstances in which it was made, and its details. The complainant may testify to the same matters and explain the timing of the complaint. The Commonwealth may not present additional complaint witnesses. The judge admits this evidence only to help the jury evaluate the complainant’s credibility, not to prove that the assault occurred, and must give a limiting instruction when the witness testifies and again in the final charge. King, 445 Mass. at 248.

King holds that first-complaint evidence serves no corroborative purpose when neither the occurrence of an assault nor consent is disputed. The judge should exclude it when identity is the only contested question.

Commonwealth v. Murungu, 450 Mass. 441 (2008), permits a later witness to substitute when the first encounter was not a complaint or the first listener had a bias or motive to minimize or distort the disclosure. The Commonwealth may not select the witness with the best memory or most details, and the judge must strike the original listener’s testimony after designating a substitute. Commonwealth v. Kebreau, 454 Mass. 287 (2009), permits a second witness only when the two disclosures concern different periods and escalating conduct. Commonwealth v. Arana, 453 Mass. 214 (2009), bars successive complaints to the same witness and testimony that the complainant told other people. Commonwealth v. Aviles, 461 Mass. 60 (2011), retained the doctrine but adopted abuse-of-discretion appellate review.

The restriction applies to the Commonwealth, not the defendant. Under Murungu, a defendant seeking to show that the proposed first complaint was misleading, inaccurate, or false may establish that the complainant first told someone else or did not complain at the time, to the person, or in the detail one would expect.

Before trial, defense counsel can move in limine to designate the witness, request a voir dire, and ask for limiting instructions when the witness testifies and during the final charge. Counsel must also object when the Commonwealth offers testimony on another stated ground that merely repeats that the complainant made a complaint. Arana holds that such testimony is inadmissible.

The Rape Shield Statute, M.G.L. c. 233, § 21B

The rape-shield statute treats reputation evidence and evidence of specific sexual conduct differently. It bars evidence of the complainant’s reputation for sexual conduct without exception. It bars evidence of specific instances of sexual conduct subject to two statutory exceptions: sexual conduct with the defendant, and recent conduct alleged to have caused a physical feature, characteristic, or condition of the complainant. The statute applies to proceedings for violations of M.G.L. c. 265, §§ 13B, 13B1/2, 13B3/4, 13F, 13H, 22, 22A, 22B, 22C, 23, 23A, 23B, 24, 24B, 50, and 51. It does not apply to the chapter 272 offenses described above.

When a statutory exception applies, the moving party must file a written motion, make an offer of evidence, and request an in camera hearing outside the jury’s presence. The judge may admit the evidence only after finding that its weight and relevance outweigh its prejudicial effect on the complainant. The judge must make that finding in writing, file it, and withhold it from the jury.

The constitutional right to effective cross-examination can require admission even when the statutory language would exclude the evidence. Commonwealth v. Joyce, 382 Mass. 222, 227 (1981), holds that the statute does not exclude specific instances of a complainant’s sexual conduct when that evidence is relevant to bias or motive to lie.

Commonwealth v. Jacques, 494 Mass. 739 (2024), holds that a complainant’s prior sexual abuse by a third party constitutes sexual conduct within § 21B. The Court also held that the defendant’s confrontation right required cross-examination when the current allegations and earlier abuse shared unique, specific, and striking similarities. Facts common to many sexual assaults do not satisfy that standard.

Counsel should present a § 21B motion under any applicable statutory exception and, when the record supports it, under Joyce and Jacques. A constitutional claim requires specific, distinctive similarities rather than generic features of sexual-assault allegations.

Privileged Records and the Dwyer Protocol

Counseling, school, Department of Children and Families, and medical records may contain the earliest accounts of the allegation. Under Commonwealth v. Dwyer, 448 Mass. 122 (2006), a defendant uses the Dwyer protocol to seek those records. Dwyer replaced the earlier procedure established through Commonwealth v. Bishop, 416 Mass. 169 (1993), and Commonwealth v. Fuller, 423 Mass. 216 (1996).

Under Dwyer, the defendant must first satisfy Mass. R. Crim. P. 17(a)(2) as construed in Commonwealth v. Lampron, 441 Mass. 265, 269 to 270 (2004): the documents must be evidentiary and relevant, not otherwise reasonably procurable in advance of trial, necessary to prepare for trial, and the application must be made in good faith and not as a general fishing expedition. Records likely to be covered by a statutory privilege remain presumptively privileged and no judicial finding of privilege is required at that stage. The records are held in court under seal and inspected only by defense counsel of record, who must first sign and file a protective order as an officer of the court barring copying and barring disclosure of the contents to any person, including the defendant. Disclosure beyond counsel requires a hearing, in camera review by the judge where necessary, and findings that copying or disclosure is necessary to prepare adequately for trial, with the judge required to consider alternatives such as stipulations or redaction.

Fuller required a good-faith, specific, and reasonable basis to believe that counseling records privileged under M.G.L. c. 233, § 20J contained relevant and material exculpatory evidence. That test required a defendant who had never seen the records to make a showing about their contents. In Dwyer, the Supreme Judicial Court replaced that test with the procedural showing under Rule 17 and permitted defense counsel, rather than the judge, to conduct the first inspection subject to a protective order.

The Limits on Expert Testimony

The Commonwealth often calls an expert to explain delayed disclosure, continued contact with the accused, or inconsistent accounts. Commonwealth v. Federico, 425 Mass. 844, 847 to 848 (1997), permits testimony on the general behavioral characteristics of sexually abused children, confined to a description of general or typical characteristics.

Federico imposes three limits. The expert may not compare the complainant’s behavior to those general characteristics, opine that the complainant was abused, or describe the typical attributes of a perpetrator. Commonwealth v. Quinn, 469 Mass. 641 (2014), also bars an expert from testifying that a child’s behavior or experience is consistent with that of abused children when a reasonable jury would understand the opinion as implicit vouching.

When the expert has examined or treated the complainant, testimony about general characteristics can become an implicit comparison to the specific case. A motion in limine should exclude case-specific facts, hypotheticals that track the complainant’s history, formulations using the words “consistent with,” and perpetrator profiles.

Digital Communications and Device Evidence

When the prosecution relies on a phone or computer, counsel should first determine whether the warrant established a nexus between the alleged offense and the device, identified the data to be seized with sufficient particularity, and authorized the scope of the extraction. The pages on phone and computer searches and illegal searches and seizures explain the governing constitutional standards. The article on Massachusetts digital search warrants addresses the required showing in the warrant application.

Counsel must also determine who created, downloaded, or controlled the file. Its presence on a shared device does not identify the responsible user. Metadata, account activity, operating-system logs, and evidence of access may distinguish among multiple users.

Before admitting text messages, social-media exchanges, or extracted images, the judge must find sufficient evidence to authenticate them. The page on admitting and objecting to digital evidence explains that foundation. When a party alleges that an image was artificially generated or digitally altered, the same page explains authentication of deepfakes and artificially generated evidence.

The image statutes require proof of different mental states. Sections 29A(a) and 29B require lascivious intent, and both subsections of § 29B include that element. Section 29B punishes possession only when the defendant intended to disseminate the material. Section 105 requires intent to conduct or conceal the activity secretly. The Commonwealth must prove the applicable mental state through the surrounding circumstances; the number of files alone does not necessarily establish it.

Forensic Evidence

DNA may establish contact, but it ordinarily does not establish whether the contact was consensual. The disputed forensic questions may instead concern the chain of custody, interpretation of a mixture, or the statistical conclusion the analyst may draw from the profile.

The absence of physical findings does not by itself establish that no assault occurred, and the Commonwealth may present expert testimony on that point. Federico permits a medical expert to explain that the absence of physical injury does not necessarily support a medical conclusion that no abuse occurred. The expert may not go further and opine that the complainant’s presentation is consistent with abuse. When an examiner performed an evaluation, counsel should review the contemporaneous notes, intake history, and source of each reported fact along with the physical findings.

Trial Preparation and Cross-Examination

When the case rests on testimony, counsel should reconstruct the sequence of disclosures rather than isolate a single statement. The relevant sources may include the first complaint, police interviews, a Sexual Assault Intervention Network interview, grand-jury testimony, a recorded forensic interview of a child, and records obtained under Dwyer. In Attorney Serpa’s experience, some variation among accounts is expected. The more significant question is whether a material detail appeared only after another person introduced it.

Those records provide the foundation for cross-examination. The first-complaint designation, § 21B ruling, and Dwyer inspection should occur before trial so that counsel can prepare from the complete admissible record rather than react to a witness’s answers for the first time before the jury.

The decision whether the defendant should give an account requires review of the evidence and any parallel proceeding. A person accused of a crime has the right not to answer investigators’ questions, and the page on the right to remain silent explains invocation and waiver. A school may apply its own participation rules in a campus proceeding, but statements made there can affect the criminal case.

Sex Offender Registry Board Classification

M.G.L. c. 6, §§ 178C to 178Q govern Sex Offender Registry Board classification. Classification is separate from the criminal case and has its own hearing, evidentiary record, and appellate procedure.

The Three Classification Levels

Section 178K(2) sets three levels. Level 1 is a determination that the risk of reoffense is low and that no public safety interest is served by public availability. Level 2 is a moderate risk with a public safety interest in public availability. Level 3 is a high risk with a substantial public safety interest in active dissemination. Only final level 2 and level 3 classifications are publicly available. For a level 3 classification the police or the Board must actively disseminate the person’s name, home and secondary addresses, work address, offense and date of conviction or adjudication, physical description and photograph, and a level 3 community notification plan requires the police department to notify organizations in the community and individual members of the public who are likely to encounter the person.

The Standard of Proof

Although § 178L(2) refers to proof by a preponderance of the evidence, that is not the constitutional standard the Board may apply. In Doe, Sex Offender Registry Board No. 380316 v. Sex Offender Registry Board, 473 Mass. 297 (2015), the Supreme Judicial Court held that the Board must prove the appropriateness of a classification by clear and convincing evidence at all three levels.

Deadlines, Reclassification, and Termination

A person who wants an evidentiary hearing must petition within twenty days after receiving notice of the recommended classification. A failure to file on time waives the hearing and makes the recommended classification and registration determination final and unreviewable.

Noe, Sex Offender Registry Board No. 5340 v. Sex Offender Registry Board, 480 Mass. 195 (2018), applies the clear-and-convincing standard to reclassification. A person seeking a lower level must first produce some credible evidence of changed circumstances. Once that threshold is met, the Board must prove by clear and convincing evidence that the current classification remains correct. If the Board fails to carry that burden, it must reduce the classification. Noe also confirms an indigent person’s statutory right to appointed counsel at a reclassification hearing.

Under § 178G, the duty to register generally ends twenty years after conviction, adjudication, or release from all custody or supervision, whichever occurs last. The twenty-year rule does not apply, and the duty never terminates, when the person was convicted of two or more qualifying sex offenses committed on different occasions, was convicted of a sexually violent offense, was determined by the sentencing court to be a sexually violent predator, or is otherwise subject to lifetime registration as determined by the Board. A person may apply to the Board to terminate the obligation by proving through clear and convincing evidence both that they have not committed a sex offense within ten years after conviction, adjudication, or release from all custody or supervision, whichever is later, and that they are not likely to endanger others.

Which Offenses Require Registration

The offense list in M.G.L. c. 6, § 178C controls whether a disposition requires registration. A first conviction of open and gross lewdness under M.G.L. c. 272, § 16 does not require registration because § 178C includes only a second or subsequent adjudication or conviction under that section. Indecent exposure under M.G.L. c. 272, § 53, punishable by up to six months in a jail or house of correction, a fine of up to $200, or both, does not appear in § 178C. Section 105 also does not appear. Counsel must account for these distinctions when evaluating a proposed disposition.

Global Positioning System Monitoring Under M.G.L. c. 265, § 47

M.G.L. c. 265, § 47 states that a person placed on probation for an offense defined as a “sex offense,” “sex offense involving a child,” or “sexually violent offense” under M.G.L. c. 6, § 178C must wear a global positioning system device. A judge may not impose that condition automatically. Commonwealth v. Feliz, 481 Mass. 689 (2019), holds that article 14 of the Massachusetts Declaration of Rights requires an individualized determination of reasonableness that balances the need for monitoring against the intrusion on privacy. Accepting a probation contract that includes monitoring does not constitute consent.

In Commonwealth v. Rodriguez, 494 Mass. 723 (2024), the Supreme Judicial Court directed the Probation Department to remove a device from any person wearing one under § 47 without a Feliz hearing and prohibited attachment until the court holds that hearing. The Court also held that an exclusion zone covering an entire city functions as banishment, imposes significant restrictions on liberty, and exceeds the limits of § 47. The Commonwealth bears the burden at the hearing. A judge may waive monitoring fees after finding substantial financial hardship.

Immigration Consequences

A noncitizen charged with a sex offense needs immigration analysis before making any decision about a plea or admission. Immigration law may attach consequences to the disposition even when the criminal court imposes little or no incarceration. The aggravated-felony definition in 8 U.S.C. § 1101(a)(43)(A) includes “murder, rape, or sexual abuse of a minor,” and subsection (I) includes an offense described in 18 U.S.C. §§ 2251, 2251A, or 2252. The definition applies to qualifying state and federal convictions and includes attempts and conspiracies. A sex offense may also constitute a crime involving moral turpitude.

The name of a Massachusetts offense does not by itself establish whether the conviction falls within a federal definition. Immigration counsel must compare the statutory elements and, when applicable, the record of conviction to the federal category while coordinating with criminal-defense counsel. The page on criminal convictions for immigrants and visa holders explains that analysis.

Professional Licensing Consequences

Arraignment creates a CORI entry that may become available to licensing boards and employers with the required level of access before the court resolves the charge. A licensed professional must determine whether the governing board requires disclosure, what event triggers the duty, when the report is due, and whether a pending charge authorizes interim action.

The obligations differ by board, license type, and the exact wording of the renewal or reporting question. A licensee should confirm the governing rule rather than assume that a charge either is or is not reportable. The pages on criminal records and CORI and criminal defense for licensed professionals explain the profession-specific triggers.

Students and the Parallel Title IX Proceeding

A sexual-assault allegation against a college or university student can produce both a criminal case and a campus disciplinary proceeding. The two proceedings use different rules and may advance on different schedules.

In the criminal case, the Commonwealth must prove guilt beyond a reasonable doubt, and the defendant has the rights to counsel, confrontation, and protection against compelled self-incrimination. Federal Title IX regulations and the school’s own published procedures govern the campus proceeding. On January 9, 2025, the United States District Court for the Eastern District of Kentucky vacated the 2024 Title IX rule nationwide in State of Tennessee v. Cardona. The United States Department of Education has since enforced the 2020 regulations, subject to the portion of § 106.45(b)(6)(i) that a federal court vacated in 2021.

Two features of the 2020 regulations matter when a criminal case proceeds at the same time. Under 34 C.F.R. § 106.45(b)(1)(vii), an institution must state whether it uses a preponderance-of-the-evidence or clear-and-convincing-evidence standard and must apply its chosen standard consistently to formal sexual-harassment complaints against students and employees. A student should confirm the standard in the school’s current procedure.

Under 34 C.F.R. § 106.45(b)(6)(i), a postsecondary institution must provide a live hearing and permit each party’s advisor to ask the other party and witnesses relevant questions and follow-up questions, including questions about credibility. The advisor, not the party, conducts the questioning directly, orally, and in real time. If a party has no advisor for the hearing, the institution must provide one without charge.

In Victim Rights Law Center v. Cardona, 552 F. Supp. 3d 104, 134 (D. Mass. 2021), the federal court vacated the sentence in § 106.45(b)(6)(i) that prohibited a decision-maker from relying on any statement by a party or witness who did not submit to cross-examination. The Department of Education no longer enforces that prohibition. The remaining regulation provides that a decision-maker may not draw an inference about responsibility based solely on a party’s or witness’s absence from the hearing or refusal to answer questions. The school’s current written procedure may provide additional rules about participation and evidence.

The campus proceeding can result in suspension or expulsion before the criminal case is scheduled for a pretrial conference. Statements to a Title IX investigator are not confidential from the criminal case, and a prosecutor may seek them. A student who assumes otherwise may provide the Commonwealth with an account that the police did not obtain.

Criminal-defense counsel and the student’s campus advisor or education counsel should coordinate before the student submits a statement or attends an interview. That coordination protects the criminal case while ensuring that the student responds to the campus proceeding under its current rules.

Courts Where Serpa Law Office Has Tried Sex Offense Cases

A sex offense case may begin in the District Court or Boston Municipal Court and proceed in the Superior Court after indictment. Attorney Joe Serpa has practiced Massachusetts criminal defense since 1995 and has tried sex-offense cases in courts across Massachusetts. The Massachusetts criminal defense results page collects these and other case results:

• In Suffolk Superior Court, Serpa Law Office obtained not-guilty verdicts in an aggravated rape case (Comm. v. KB) and an aggravated assault and battery with intent to commit rape case (Comm. v. JB).
• In Middlesex Superior Court, the firm obtained not-guilty verdicts on charges of rape or date rape and indecent assault and battery (Comm. v. NA).
• In Plymouth County Superior Court, the firm obtained a not-guilty verdict in a joint-venture rape case (Comm. v. MR).
• In Essex County Juvenile Court, the firm obtained a not-guilty verdict in a youthful-offender sexual-assault trial for an offense carrying a possible life sentence (Comm. v. LF).
• In Bristol County District Court, the firm obtained not-guilty verdicts on three counts of indecent assault and battery and one count of witness intimidation (Comm. v. RJ).
• In Worcester County District Court, the firm obtained a not-guilty verdict on an indecent assault and battery charge (Comm. v. TH).
• In the BMC Central Division, the firm obtained a not-guilty verdict on a charge of photographing an unsuspecting nude person in a Northeastern University case (Comm. v. SM).

Contact Serpa Law Office at 617.936.0201 for a confidential consultation. Early defense work includes identifying the exact charged section, preserving messages and device data before they disappear, locating witnesses while their memories remain current, and obtaining each account given before the police completed the report. In Attorney Serpa’s experience, beginning that investigation as close to the alleged incident as possible gives the defense the best opportunity to preserve evidence.
