How Judge Guzman decides

Patterns drawn from this judge's own signed orders. Every observation links to the order it came from.

What persuades

In Roman v. Lahey, Guzman dismissed medical-malpractice claims after the plaintiff failed to disclose an expert and could not prove the required standard of care.

“because Plaintiff will be unable to prove the medical standard of care required for his claims, the claims must be dismissed.”

In a dispute over damage to a classroom floor, Guzman found the policy's collapse provisions ambiguous and construed them in favor of the insured. She held that the general moisture exclusions did not bar coverage, while leaving the disputed question whether the floor had collapsed under the policy for a jury.

“because 'ambiguities in the Policy result in coverage for the collapse,' the general exclusions for 'condensation of humidity, moisture, or vapor' are inapplicable.”

In Citation Insurance Co. v. Broan-NuTone, Guzman granted summary judgment in a products-liability case after finding the plaintiff lacked admissible evidence of a design or manufacturing defect.

“Plaintiff lacks admissible evidence to show either a design defect or a manufacturing defect, and even if its late-disclosed evidence was admissible, it is insufficient.”

Procedural preferences

In Wea v. Carvajal, she dismissed a landlord’s suit concerning state housing-court proceedings for lack of federal subject-matter jurisdiction and did not reach the defendants’ merits arguments.

“When a federal court concludes that it lacks subject matter jurisdiction over a case, it is precluded from rendering any judgments on the merits of the case.”

In Social Security suits she requires the claimant to have exhausted administrative remedies and obtained a 'final decision' under 42 U.S.C. 405(g) before judicial review; absent a waiver of exhaustion, the proper vehicle for dismissal is Rule 12(b)(6) because the court lacks the statutory power to grant relief (Smith v. Berryhill).

“without any such waiver the proper vehicle for dismissal is Fed. R. Civ. P. 12(b)(6) because the court lacks the statutory power to grant relief.”

She treats reconsideration as a narrow remedy rather than a second round of briefing. A party must identify new evidence, an intervening change in controlling law, clear legal error, or manifest injustice; repeating arguments already considered does not suffice.

“A motion for reconsideration is not an occasion for parties to ‘rehash arguments previously rejected or to raise ones that’ could or should have been made before a judgment was issued.”

In Jean-Paul, Guzman found good cause for late service after a self-represented plaintiff made an initial effort and reasonably believed from communications with the defendant that service was complete. She still required a clearer amended pleading.

“Considering the totality of the circumstances, the Court concludes Plaintiff has demonstrated good cause under Rule 4(j).”

Cautions

In a land-use dispute, Guzman granted summary judgment on the developers' substantive due process claims. She found the alleged permit delays and disputed gravel-removal fee did not shock the conscience, and she dismissed the remaining state-law claim without prejudice.

“the claim is 'too typical of the run of the mill dispute between a developer and a town planning agency,' and thus does not rise to the level of a due process violation.”

In Roman v. Lahey, she dismissed medical-negligence claims after denying the plaintiff’s third and fourth requests to extend the expert-disclosure deadline, leaving him unable to prove the medical standard of care.

“the Court denied Plaintiff's third and fourth emergency motions for extension of time to disclose an expert, and noted plaintiff would be barred from disclosing an expert in this case.”

In Morin v. Quinsigamond Community College, she denied a mandatory preliminary injunction seeking a grade change to permit a nursing exam because delayed professional progress and financial losses did not establish irreparable harm.

“Because a mandatory preliminary injunction alters rather than preserves the status quo, it ‘normally should be granted only in those circumstances when the exigencies of the situation demand such relief.’”

A snapshot on that date: matters listed may since have been decided or reassigned. A motion referred to a magistrate judge is counted for both judges. Motions in multidistrict litigation, section 2255 cases and Social Security appeals are not counted, and a very large three-year count is generally a multidistrict docket.

How long civil cases take in this court

For the whole of U.S. District Court for the District of Massachusetts, not for Judge Guzman: median time from filing to disposition of the civil cases the court closed in the 12 months ending September 30, 2025, as reported by the Administrative Office of the U.S. Courts.
