Selected cases

  • Bellin v. Kelley , 435 Mass. 261 (2001)
    According to this decision, an investigating police officer did not act wrongly in revealing an employee's CORI history to an employer. The decision further stated that an employer could fire the employee for the employee's failure to submit to a polygraph test. Summary judgments were thus granted for both the police officer and the employer who were among the defendants in the matter.

Web sources

  • Consideration of arrest and conviction records in employment decisions under Title VII of the Civil Rights Act of 1964, EEOC.
    Under the guidance, background checks must be job-related and consistent with business necessity. When considering conviction records, employers must look at (1) the nature and gravity of the offense, (2) the amount of time that has passed since the offense, and (3) the nature of the position sought. According to the EEOC, arrest records are never job-related and consistent with business necessity because applicants must be treated as innocent until proven guilty.

Appeals Court is entitled to access probation-related documents according to the Criminal Offender Records Information System, regardless of whether or not the records were included within the record of an appeal.

Media access and dissemination

Globe Newspaper Co. v. District Attorney for Middle Dist., 439 Mass. 374 (2003)
Newspaper had sought disclosure of docket numbers of criminal cases involving municipal corruption, prosecuted in public judicial proceedings. Among its findings, court held that CORI statute did not prevent disclosure of criminal record information, but newspaper only had a disclosure right to the extent the requested information correlated with information available from court records or other public records.

Sealing, expungement, and pardons

Massachusetts laws

Court Rules


  • Chief of Police of Shelburne v. Moyer, 16 Mass. App. Ct. 543 (1983)
  • "Statute providing for sealing of record of a person convicted for possession of certain controlled substances does not preclude use by a chief of police...of departmental records which are not public records, maintained by police and other law enforcement agencies."
  • Comm. v. Boe , 456 Mass. 337 (2010)
    A judge does not have the authority "to order the Commissioner of Probation (commissioner) to expunge a defendant's record where the criminal complaint was dismissed because its issuance was premised on a mistake." "Massachusetts appellate decisions have construed the unambiguous language of G.L. c. 276, § 100C , as conferring on a judge the authority, in appropriate circumstances, to order sealing, but not expungement, of the probation and court records of dismissed prosecutions."
  • Comm. v. Gavin G. , 437 Mass. 470 (2002)
  • While Juvenile Court judges have the authority to order expungement of police records, they do not have authority to order expungement of probation records.
  • Comm. v. Pon , 469 Mass. 296 (2014).
    Establishes a new standard and procedure for sealing of a criminal case ending in a dismissal or entry of a nolle prosequi, making it easier to have those records sealed.
  • Comm. v. S.M.F. , 40 Mass.App.Ct. 42 (1996)
    "When statute governing sealing of certain criminal records is applicable, exercise of judicial power of expungement is no longer within authority of judge, but, when statute or other confidentiality statutes are not applicable, trial courts may invoke their inherent power to order expungement of criminal records."
  • Comm. v. Zoe, 95 Mass. App. Ct. 500 (2019)
    When a criminal record is sealed under the automatic sealing procedures of G.L. c.276, § 100A, a judge has "no authority to override the terms of the statute providing for such automatic sealing." Therefore, a motion to unseal the records was "moot from its inception."
