During a Torts class last semester, we were discussing various applications of Judge Learned Hand’s formula for negligence, when a student asked, “Why isn’t it negligent to hold pinata parties?” To which I replied, “It probably is!”
Judge Hand’s formula, explained in a famous case called United States v. Carroll Towing Co., is that if the burden of avoiding a risk is less than than probability of the risk resulting in harm multiplied by the potential severity of the harm, it is negligent to engage in the conduct.
As applied to pinata parties, the only burden to avoiding the risk is to choose a different, safer game to entertain kids at a party, compared to the risk that a blindfolded kid swinging a bat could whack some other kid in the head and cause serious injury.
Some students thought I was just being, as usual, overly cautious Tortman, but then I came across this sign at a picnic area while bike-riding in Shelby Farms. Vindicated.
But wait, what is up with that prohibition on metal detecting?
