Nolle Prosequi in Massachusetts: Meaning, Procedure and Case Records

Nolle prosequi is a formal decision by the prosecution not to continue prosecuting particular charges. A Massachusetts court record may abbreviate the term as Nol Pros or NP. It describes a disposition of charges, not an offense or a defendant's plea. Its effect should be assessed from the filed documents and procedural history.

1. Does it end every charge in the case?

A case may contain several charges, and a nolle prosequi may cover all of them or only selected counts. An NP entry for one count does not establish that the whole case has ended. Check each charge and any remaining court orders.

Keep the docket and disposition documents rather than relying on a verbal summary. A statement that the case was dropped may omit an unresolved count or fail to describe what was actually filed. Those details can matter when explaining the result later.

2. What does Massachusetts Rule 16 require?

Massachusetts Criminal Procedure Rule 16(a) first sets the time within which the prosecution may use this procedure:

A prosecuting attorney may enter a nolle prosequi of pending charges at any time prior to the pronouncement of sentence or the imposition of probation or the entry of an order of continuance without a finding.

Remaining court dates do not establish that a nolle prosequi is available at every stage. The rule also requires a record of the prosecutor's reasons:

“A nolle prosequi shall be accompanied by a written statement, signed by the prosecuting attorney, setting forth the reasons for that disposition.”

The prosecutor must sign the written statement explaining the disposition. Read that document together with the docket to confirm the result. A CWOF is a different procedure: it continues the case under conditions without entering a guilty finding, rather than recording the prosecution's decision not to proceed.

3. Is the judge's approval required?

Entering a nolle prosequi differs from filing a motion that asks the judge to dismiss a case. Massachusetts court Guideline 8:11 explains:

The Commonwealth can terminate the proceeding without court permission or approval

This authority belongs to the prosecution. A complainant's wish not to continue does not itself establish that an NP disposition has been entered. Confirm the prosecutor's filing and the court record; a private conversation or informal message should not be treated as proof that the prosecution ended.

4. Is it the same as an acquittal?

Nolle prosequi and acquittal ordinarily describe different dispositions. Rule 16(b), however, specifies circumstances in which a nolle prosequi has the effect of an acquittal:

After jeopardy attaches, a nolle prosequi entered without the consent of the defendant shall have the effect of an acquittal of the charges contained in the nolle prosequi.

Whether jeopardy has attached depends on the procedural stage, not simply the number of court appearances. The defendant's consent also matters. Before concluding whether charges can be brought again, counsel should review the trial history, the covered charges and the record of consent. The label alone cannot answer that question.

5. Are the records automatically erased?

Ending prosecution does not resolve every question about access to the records. Chapter 276, section 100C provides:

In any criminal case wherein a nolle prosequi has been entered, or a dismissal has been entered by the court, and it appears to the court that substantial justice would best be served, the court shall direct the clerk to seal the records of the proceedings in his files.

An NP docket entry is not itself a sealing order. Review the applicable standard, eligibility and application procedure, and confirm whether relief has actually been granted. Sealing also differs from expungement. Retain disposition documents even when a public-record concern appears resolved, because later applications may ask for information that requires them.

6. What information should you retain?

Keep the prosecutor's signed statement, the court docket and relevant orders. Confirm which charges were covered, when the entry occurred and whether any matters remain pending. These documents make it possible to explain the result accurately.

Employment, licensing and immigration applications may distinguish between arrests, charges, convictions and other dispositions. Answer the particular question under the applicable law rather than substituting not guilty for every outcome that ends prosecution. Noncitizens should review the disclosure requirements and supporting documents before submitting a form or attending an interview.
