How Judge Mahoney decides

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

What persuades

Mahoney treated an actually paid liability as the practical point at which a cash-basis taxpayer's loss became deductible.

“the. customer sustained the loss when the certainty of loss was definitely ascertained and when the indebtedness was actually paid.”

In patent cases, he required an enabling description and would not allow marketplace success to rescue an otherwise invalid specification.

“The emphasis placed upon the commercial success of the alleged invention cannot cure its invalidity.”

Procedural preferences

Mahoney enforced territorial limits on service over foreign corporations when the action arose elsewhere and the defendant had not consented to the forum.

“The defendant has not consented1 to the bringing of this action in this district.”

He resolved multi-count pleading attacks count by count, allowing viable alternative negligence theories to proceed while rejecting the deficient count.

“The demurrer to the first count is sustained. It is overruled as to the second, third, fourth, and fifth counts.”

Cautions

Mahoney required claimants to carry their evidentiary burden even after overcoming a threshold limitations defense.

“The burden of proof which rests upon the plaintiff to show that he was totally and permanently disabled while the policy of insurance was in effect has not been established.”
