For further assistance you may consult the Finding Aids for the County at the State Archives (Reference Desk) or Contact the Judicial Archives. You should try to find as much information about the case as you can before you contact them. We were told that the person's name, year of the trial, as well as the type of crime is helpful.

Employment and CORI access

  • 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.

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.

Court Rules

BMC Standing Order 1-09 (Revised): For the Sealing of Three or More Dismissals and Non-Conviction Criminal Records


  • Commonwealth 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.
  • Chief of Police of Shelburne v. Moyer, 16 Mass.App.Ct. 543, 453 N.E.2d 461 (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."
  • Commonwealth 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."
  • Commonwealth v. Doe , 420 Mass. 142, 648 N.E.2d 1255 (1995)
    Court provides an in-depth discussion regarding the sealing statutes, MGL c. 276 secs. 100A-C. Specifically, it clarifies the phrase "substantial justice," which is used in MGL c.276 sec.100C as follows: "the value of sealing to the defendant [must] clearly outweigh the constitutionally-based value of the record remaining open to society." Id., at 151.
  • Commonwealth 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.
  • Commonwealth v. Moe , 463 Mass. 370 (2012)
    Relying on Commonwealth v. Boe , court ruled that a judge lacked the authority to expunge a criminal record, even where it was the result of a fraud on the court.
  • Commonwealth v. S.M.F. , 40 Mass.App.Ct. 42, 660 N.E.2d 701 (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."
