Common questions
Frequently Asked
5
How does legal negligence differ from recklessness?+
Legal negligence requires only a failure to exercise the standard of care a reasonably prudent person would observe. Recklessness demands a conscious disregard of a substantial and unjustifiable risk. The Restatement expressly excludes reckless conduct from the definition of negligence.
Can evidence of subsequent repairs prove negligence?+
No. Federal Rule of Evidence 407 bars admission of subsequent remedial measures to prove negligence or culpable conduct. The evidence may be admitted only for other limited purposes such as impeachment or proving feasibility of precautions.
When does a landlord remain liable for an independent contractor's negligence?+
A landlord who retains control over a portion of the property and entrusts repairs of that portion to a contractor remains liable for the contractor's negligence in performing the work. The landlord cannot escape responsibility by delegating the duty it owes to tenants and their invitees.
What mental state satisfies criminal negligence for involuntary manslaughter?+
Criminal negligence requires a gross deviation from the standard of care a reasonable person would observe that creates a high risk of death or serious bodily harm. This standard is higher than ordinary civil negligence but lower than the malice required for murder.
Does a private plaintiff in a defamation case involving a matter of public concern need to prove negligence?+
Yes. A private plaintiff must prove at least negligence regarding the falsity of the statement. Recovery of presumed or punitive damages additionally requires proof of actual malice.
