How Judge Sullivan decides

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

What persuades

In Poe v. Wal-Mart, Sullivan granted defense summary judgment because the plaintiff lacked evidence of actual or constructive notice and Maryland law did not recognize the proposed mode-of-operation theory.

“Walmart's Motion for Summary Judgment (ECF No. 15) is GRANTED.”

In Patterson v. Howard Memorial Hospital, Sullivan granted the employer summary judgment because the plaintiff did not establish causation or pretext on her disability-discrimination and retaliation claims.

“HMR's Motion for Summary Judgment (ECF No. 38) will be granted, and judgment will be entered in favor of HMR.”

In Mason v. 7-Eleven, Sullivan granted the franchisor summary judgment because the franchisee was an independent contractor over which the franchisor lacked the right of control required for agency liability.

“7-Eleven's Motion (ECF No. 28) is GRANTED.”

Cautions

In Rush v. O'Malley, Sullivan affirmed the benefits decision because substantial evidence supported the administrative law judge's residual-functional-capacity finding.

“the Commissioner's Motion for Summary Judgment (ECF No. 11) will be GRANTED.”

In Niccole N., Sullivan remanded a benefits denial because the balance restriction in the residual-functional-capacity finding could not be reconciled with light-work standing requirements. He left the ultimate disability determination to the agency.

“Under that standard, I will deny both motions and remand the case for further proceedings.”

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

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).
