Common questions
Frequently Asked
3
Does malo animo require proof of personal hostility toward the victim?+
No. Under the definition, malo animo is shown by spiteful or ill-willed conduct even without personal animus. The mental state alone supports punitive damages or elevates the tort when the actor acts without legitimate purpose.
Supporting sources
When does malicious conduct make a private nuisance unreasonable?+
An intentional invasion is unreasonable if the conduct is spiteful or offends common decency with no legitimate utility. Retaliatory placement of offensive objects directed at neighbors meets this standard without further balancing.
Supporting sources
Can punitive damages be awarded in a retained heartbalm action?+
Yes. When the defendant acted maliciously in breaching a promise to marry, the tort aspect of the claim permits punitive damages in addition to actual reliance losses.
