Leo Theodore Sorokin
How Judge Sorokin decides
Patterns drawn from this judge's own signed orders. Every observation links to the order it came from.
What persuades
He declines to extend Massachusetts substantive law beyond its 'well-marked boundaries': where a party urges a common-law right (here, an insured's recovery of mitigation costs from its insurer) that no SJC, Massachusetts Appeals Court, or First Circuit decision recognizes, he will not create it, and a sister judge's D. Mass. decision is persuasive but not controlling. Ground a state-law theory in binding Massachusetts authority -- a lone district-court opinion or out-of-state cases will not carry it in his court.
“In these circumstances and mindful of the admonition that '[f]ederal courts are not free to extend the reach of state law,' the Court declines to 'extend state law beyond its well-marked boundaries in an area . . . that is quintessentially the province of state courts.'”
He treats the statute of limitations as an affirmative defense the movant must establish 'with certitude' at the pleading stage, and pushes fact-intensive timeliness questions (willfulness, continuing-violation, recoverable damages) past the motion to dismiss to summary judgment or trial. Do not expect to win a limitations dismissal on a 12(b)(6) where the accrual or continuing-violation facts are contested.
“Given the framework governing review of a complaint on a motion to dismiss, coupled with the burden Harvard bears on its affirmative defense, the Court concludes Harvard has failed to establish at this stage that the EPA claim is limited to two or three years. In this case, these are questions better determined based on the fuller factual record typically available at summary judgment or trial.”
Procedural preferences
He enforces Local Rule 56.1 on summary judgment: a party (even a pro se one) who files no statement of undisputed material facts and does not controvert the opponent's statement has the opponent's facts deemed admitted, which can be dispositive. File a proper LR 56.1 statement and response, or risk conceding the factual record.
“In the ordinary course, failure to file such a statement constitutes 'grounds for denial of the [summary judgment] motion,' and failure to controvert material facts set forth in an opposing party's statement is deemed an admission for purposes of a summary judgment motion. See Local Rule 56.1”
He affords pro se litigants real solicitude at the pleading stage: a pro se complaint is read with 'an extra degree of solicitude,' and a bare-bones, unnumbered 'garden-variety' claim that pleads the basic who/what/when/where can clear Rule 8 even without a cited statute -- but pro se status does not excuse pleading each material element of an actionable theory.
“And, while the Court agrees that the amended complaint is not perfect, inasmuch as it does not set forth the federal statute under which Collymore appears to be proceeding and does not include numbers to the four paragraphs, it meets the low bar of meeting the basic pleading requirements to state a claim upon which relief can be granted.”
Cautions
Even an unopposed motion to dismiss is decided on the merits: he will examine whether the complaint is formally sufficient rather than grant by default, so an opponent's silence is not a free win and a movant cannot rely on non-opposition alone. He construes documents integral to the complaint (notes, contracts, public records) at the 12(b)(6) stage without converting to summary judgment.
“Although Lemos has not opposed this motion, the Court addressed the merits of each claim, as 'the mere fact that a motion to dismiss is unopposed does not relieve [this Court] of the obligation to examine the complaint itself to see whether it is formally sufficient to state a claim.'”
