How Judge Sorokin decides

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

What persuades

In Ken’s Foods v. Steadfast Insurance, Sorokin declined to recognize a Massachusetts common-law right to recover mitigation costs from the insurer where the cited controlling authorities did not establish that right.

“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.'”

In Stone v. Harvard College, Sorokin declined to resolve several Equal Pay Act limitations questions on the pleadings because Harvard had not established the affirmative defense with the certainty required at that stage.

“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

In Jones v. Commonwealth of Massachusetts, Sorokin applied Local Rule 56.1 in the prisoner’s summary-judgment case: the plaintiff filed no statement of undisputed material facts or response controverting the defendants’ statement.

“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”

In Collymore’s pro se retail-discrimination suit, he denied dismissal of the amended complaint because its allegations supported a racial-discrimination claim despite lacking a statute citation and numbered paragraphs.

“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

In Lemos v. Bank of America, Sorokin examined the merits of an unopposed motion to dismiss, including documents integral to the complaint, and dismissed the mortgage claims after finding the complaint insufficient.

“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.'”

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 Sorokin: 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.

The table leaves out prisoner petitions, land condemnations, deportation reviews, recovery of overpayments and enforcement of judgments, and reports no median for fewer than 10 cases. A district that closed a large multidistrict litigation in the period shows very large counts and long medians for that year. Source: Table C-5, U.S. District Courts (spreadsheet).
