How Judge Harpool decides

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

What persuades

At the pleading stage he is plaintiff-favorable on motions to dismiss, especially in antitrust: he applies the Eighth Circuit's reluctance to resolve market-definition questions on the pleadings and will let even 'thin' allegations proceed to discovery. Defendants should usually save market-definition and merits attacks for summary judgment.

“Eighth Circuit courts are particularly reluctant to dismiss an antitrust suit at the pleadings stage, as 'proper market definition can be determined only after a factual inquiry into the commercial realities faced by consumers.'”

At summary judgment he decides on the narrowest dispositive ground and declines to reach alternative theories in the interest of judicial efficiency. Lead with your single strongest dispositive argument rather than spreading effort across every theory.

“The Court, having granted summary judgment based on Plaintiffs having to bring their claim as a compulsory counterclaim in the first arbitration and in the interest of judicial efficiency, need not proceed on the issue of res judicata.”

Procedural preferences

Treats a party's failure to respond to an argument as a concession of it. Respond to every distinct argument raised against you, including in a summary-judgment opposition.

“This Court agrees with Defendants that the contract between Plaintiff and Defendants precludes Plaintiff's unjust enrichment allegation in Count Three.”

On exemption and other fact-intensive defenses he denies summary judgment where the substance of the duties (not the job label) is genuinely disputed; he reserves such questions for the factfinder.

“this Court finds that material disagreement exists between the parties related to the nature of Plaintiff's professional duties as an office manager at the Dealership, thereby precluding summary judgment.”

Applies Missouri substantive law strictly to the elements of a claim: there is no fiduciary duty in an ordinary borrower-lender relationship (defeating equitable-accounting claims), and a punitive-damages claim must be tethered to a properly pled independent and willful tort.

“The relationship between borrower and lender is a debtor-creditor, not a fiduciary relationship.”

Cautions

He penalizes parties who misstate the holdings of the cases they cite, and will say so bluntly when the cited precedent cuts against the citing party. Cite authority accurately; do not overstate that opposing language is 'identical'.

“This demonstrates, rather clearly, that Defendant Howard's claim about identical language is meritless.”

He construes asserted Eleventh Amendment immunity waivers narrowly and requires the most express federal-court language; a state-law or state-court waiver will not subject a state entity to suit in federal court.

“The CEFA does not contain 'the most express language' or 'overwhelming implication' that it intends to waive its immunity in federal courts.”
