I disagree with that web site, then.
The index to Corbin, who is the acknowledged expert on contract law, includes reasonable expectation, reasonable price, reasonable satisfaction, reasonable time, but not reasonable person.
See, instead, Prosser and Keaton on Torts, the basic authority on torts, Fifth edition, Section 32. The Reasonable Person.
The reasonable person standard is a negligence standard. It applies to tort law.
Black's Law Dictionary, the gold standard of legal dictionaries: "Reasonable man doctrine or standard. The standard which one must observe to avoid liability for negligence is the standard of the reasonable man under all circumstances, including the foreseeability of harm to one such as the plaintiff." That's the complete defintiion.
Negligence is a tort, not a contract, doctrine.
Your site may be trying to simplify the law, but it's just plain getting it wrong. |
