Margaret R. Guzman
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 medical-malpractice cases she enforces the Massachusetts rule that expert testimony is required 'in almost every instance' to establish the standard of care and causation; absent a disclosed expert (and where the case is not the rare 'gross or obvious' one a lay jury could decide), the claims are dismissed as unprovable.
“because Plaintiff will be unable to prove the medical standard of care required for his claims, the claims must be dismissed.”
Guzman construed internally inconsistent collapse language against the insurer, finding that a provision which effectively limited coverage to a building reduced to rubble was ambiguous. That ambiguity left the coverage question for the jury and prevented the insurer from relying on general exclusions at summary judgment.
“because 'ambiguities in the Policy result in coverage for the collapse,' the general exclusions for 'condensation of humidity, moisture, or vapor' are inapplicable.”
In products-liability cases she grants summary judgment where the plaintiff lacks admissible expert evidence of a defect and causation -- to prevail on either a negligence or a breach-of-warranty theory the plaintiff 'must present evidence of a defect' -- and she treats a late-disclosed expert opinion as excludable and an unbriefed claim as waived.
“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
She resolves subject-matter jurisdiction before the merits and will not render any merits judgment once jurisdiction is wanting; a complaint that merely checks the 'federal question' box without pleading a federal statute/treaty/constitutional provision, and whose parties are non-diverse, is dismissed under Rule 12(b)(1)/12(h)(3).
“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.”
Cautions
Section 1983 substantive-due-process claims against municipalities face a very high bar in her courtroom: a land-use 'run of the mill dispute between a developer and a town planning agency' -- even alleging bad-faith permit delays or a discriminatory fee -- does not 'shock the conscience' without racial animus or fundamental procedural irregularity, and once the federal claims fail she declines supplemental jurisdiction over the state-law claims.
“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.”
She enforces scheduling and expert-disclosure deadlines strictly: after granting several extensions she will deny further emergency extensions, bar a party who never disclosed an expert from doing so, and then dismiss claims that require that expert -- a serial-delay litigant can lose the case on the deadline, not the merits.
“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.”
A request for mandatory preliminary relief must show more than delayed professional progress or monetary loss. When the requested order would alter the status quo before a merits decision, she requires an urgent, non-compensable injury and will deny relief where later damages could address the 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.’”
