Tedla v. Ellman was a 1939 New York Court of Appeals case that was influential in establishing the bounds of the negligence per se doctrine. Ordinarily, a statutory violation automatically constitutes negligence. However, the court, in an opinion written by Irving Lehman, instead held that because this violation occurred in a situation not anticipated by the drafters of the statute and the violation was in keeping with the spirit of the statute, it did not constitute negligence.
