How Judge Parker decides

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

What persuades

On FLSA collective certification she holds plaintiffs to the 'modest factual showing' standard and will deny conditional certification (without prejudice) where the record does not yet support that the putative members were similarly situated -- a meaningful gate for employment-side plaintiffs given her labor-and-employment background.

“Plaintiffs now move for conditional certification of their FLSA claims as a collective action ... For the reasons stated below, Plaintiffs' motion is denied without prejudice.”

On discovery directed at the government in constitutional litigation she enforces governmental privileges firmly: a subpoena to a Governor for non-public documents about a statute's purpose and tailoring can be quashed as both irrelevant and protected by legislative, deliberative-process, and attorney-client privilege.

“For the reasons that follow, the Governor's motion to quash is GRANTED.”

Procedural preferences

Her R&Rs are adopted in full, including over a pro se litigant's objections, after the district judge's de novo review -- a signal that her recommendations are well-grounded. She also actively manages her consent Social Security docket toward efficient disposition, frequently resolving cases by stipulated sentence-four remands.

“the Court, after a de novo review of the objected-to aspects of the Report, adopts the Report in its entirety, and therefore grants in part, and denies in part, Gaughan's motion to amend.”
