How Judge O'Sullivan decides

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

What persuades

In Hervas v. Commissioner of Social Security, O'Sullivan recommended granting the Commissioner's summary-judgment motion; the district judge adopted his recommendation and affirmed the benefits decision.

“ADJUDGED that Defendant's Motion for Summary Judgment is GRANTED. ... for the reasons in Magistrate O'Sullivan's Report and Recommendations that the Court now adopts”

In Nunez v. Commissioner of Social Security, O'Sullivan recommended granting the claimant's summary-judgment motion and denying the Commissioner's; the district judge adopted the recommendation and remanded the benefits case.

“he recommended that (1) the Plaintiff's Motion should be granted ... The Plaintiff's Motion [ECF No. 21] is GRANTED.”

Procedural preferences

In Perez v. Garcia, he recommended denying both sides' summary-judgment motions except where the plaintiffs' motion was unopposed. He also applied judicial estoppel to conflicting defense positions.

“the Plaintiffs' motion for summary judgment is denied except where unopposed”

Cautions

In Witkin Design Group v. Travelers, he recommended granting the insurer's summary-judgment motion on the duty to defend after reviewing the underlying allegations.

“the undersigned respectfully recommends that Travelers' Motion for Summary Judgment Regarding the Duty to Defend (DE# 25, 9/29/16) be GRANTED”
