How Judge Robertson decides

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

What persuades

On a pretrial-detention motion she gives controlling weight to a defendant's demonstrated record of compliance during a prior release over the statutory presumption: a defendant who appeared as required for months on comparable state charges, with strong community ties and no prior record, can rebut the Bail Reform Act presumption even on a serious fentanyl/firearm indictment. To defeat detention before her, marshal concrete evidence of past compliance and community ties.

“Most persuasive to the court is that fact that Defendant has been on pretrial release on state court charges for some seven months, facing a sentence similar to the sentence he faces in this court. He did not leave the jurisdiction, and he has consistently appeared as required”

Procedural preferences

She enforces Local Rule 56.1: when the non-movant fails to file a counter-statement controverting the movant's statement of undisputed material facts, those facts are deemed admitted and summary judgment follows. File a record-cited LR 56.1 counter-statement to create a triable dispute.

“When moving parties submit statements of undisputed material facts and the nonmovant fails to file a counter statement identifying evidence of factual disputes, the facts set forth by the moving parties are deemed admitted. Local Rule 56.1.”

She will deny leave to amend on futility grounds rather than let a marginal new claim proceed, even where the opposing arguments against amendment otherwise fail. In one prisoner civil-rights case she rejected all of the defendants' objections to a proposed claim but denied amendment anyway because the new theory was not yet ripe. Anticipate a genuine futility analysis on any motion to amend, not just a rubber-stamp under the liberal Rule 15 standard.

“While none of Defendants' arguments are availing, the court nevertheless concludes that Plaintiff's proposed amendment is futile on another ground.”

Cautions

Section 1983 suits that effectively ask a federal court to revisit a final state-court ruling are dismissed with prejudice on Rooker-Feldman and judicial-immunity grounds; she does not treat a due-process framing as an escape hatch around those doctrines when the injury traces to the state judgment itself.

“The federal district court lacks jurisdiction to consider whether the Justices of the MAP violated Plaintiff's due process rights when they awarded Ms. Staub attorney's fees and costs.”
