We won summary judgment in Franklin County, Ohio, for a large supermarket chain in a slip-and-fall case. The plaintiff alleged he slipped and fell in the parking lot on ice that remained more than two days after the most recent snow fall and after the lot had been plowed and salted by a co-defendant. The plaintiff’s expert opined that no amount of remaining snow or ice is acceptable and that the standard of care according to the Ohio Building Code requires complete removal in order to maintain a “slip-resistant” surface. However, in Ohio, a premises owner is not liable for natural accumulations of snow and ice because persons are expected to appreciate the danger. The plaintiff’s expert did not opine as to what the defendants should have done, other than to completely remove the snow and ice. The court struck the plaintiff’s expert’s untested opinion as being unhelpful to a jury and found that the Ohio Building Code did not apply to the plaintiff’s pleadings without a claim for negligence per se. In disregarding the expert opinions, the court also found that the remaining snow and ice was “natural,” even though there had been attempted removal.
