I find it absolutely intriguing that when I do an internet search for Butterfield v. Forrester, most of the websites mentioning this case (1809, King's Bench, dealing with contributory negligence) are from economists teaching economic analysis of law. Did we ALL receive TWLDs from Henry Manne?
Note: TWLD = two-week-law-degree (so named by Steve Margolis). Every summer for decades, Henry Manne ran a two-week programme designed to cram almost all of first year law into a very intensive two-week course. We all seem to remember this case from Bob Summers' introduction to tort law.
