Hotel Rebuttal Campaign
Grand View Hotel posted false reviews claiming bedbugs at Maple Lane Inn. Maple Lane hired exterminators, paid for lab tests, and ran corrective ads to restore guest confidence. These outlays qualify as mitigation costs that reduce the inn's pecuniary loss from lost bookings.

Mrs. Cipollone continued smoking after warnings and later required surgery. Her estate sought full medical damages, but the court considered whether expenses for smoking-cessation programs would have constituted recoverable mitigation costs.

Common questions
Frequently Asked
5
What expenditures qualify as mitigation costs in a tort action?+
Mitigation costs include reasonable outlays for inspections, treatments, or corrective advertising that directly counteract the harm. The Restatement (Second) of Torts § 920 addresses related benefit offsets in mitigation of damages.
Does a plaintiff's refusal of offered treatment bar recovery of later complications?+
Yes when the refusal is unreasonable and increases harm. The duty to mitigate damages appears in uniform landlord-tenant statutes and is applied by analogy in tort.
How do mitigation costs affect damages in injurious falsehood cases?+
A plaintiff may recover reasonable costs of corrective publicity along with other losses when those outlays mitigate the harm. Restatement (Second) of Torts § 920 supplies the equitable framework for such offsets.
When is a plaintiff's mitigation effort considered reasonable in contract cases?+
Reasonable efforts satisfy the duty to mitigate under the Uniform Residential Landlord and Tenant Act § 604(d). The landlord must make reasonable efforts to relet without priority over other units.
Does the duty to mitigate require exploring every possible alternative before breach?+
No. The duty arises after the breach or harm occurs. Uniform Residential Landlord and Tenant Act § 104(b) simply requires mitigation once relief is sought.
