How Judge Wolf decides

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

What persuades

On a motion to dismiss he applies the Twombly/Iqbal plausibility standard strictly and will look to documents incorporated into or central to the complaint: where an authentic document contradicts a pleaded allegation, the document controls and the threadbare allegation is not accepted as true. A plaintiff opposing dismissal should plead concrete facts and reconcile them with the contract or record documents the claim depends on, not rest on conclusory assertions.

“When such documents contradict an allegation in the complaint, the document trumps the allegation.”

In consumer suits against regulated products he takes federal preemption seriously as a threshold merits defense, dismissing state-law consumer-protection and unjust-enrichment claims that conflict with the federal regulatory scheme governing the product. Framing a claim so it does not require the defendant to have done something federal law forbids or prevents is decisive.

“Defendants' Motion to Dismiss First Amended Complaint, (Docket No. 50) is ALLOWED, and this case is DISMISSED.”

He treats expert-evidence gatekeeping as potentially dispositive: excluding a plaintiff's liability expert under the reliability standard can remove the only support for an essential element and lead directly to summary judgment for the defendant. Invest early in an admissible, methodologically defensible expert, because losing the Daubert motion can end the case.

“Therefore, judgment will be entered for the defendant.”
