We won a motion for summary judgment in a slip and fall case in Pennsylvania. The plaintiff suffered a hip fracture when he fell on the defendant’s sidewalk while delivering a food order. At the time of the accident, there was an active freezing rain and sleet storm, and generally slippery conditions prevailed. We filed a motion for summary judgment based on the “hills and ridges” doctrine. The plaintiff argued that the doctrine was inapplicable due to human intervention that allegedly altered the natural accumulation. The defendant had applied rock salt to the sidewalk approximately 45 minutes prior to the accident. In granting our motion for summary judgment, the court found there was no evidence that the application of rock salt created a dangerous condition or increased the natural hazards of the existing ice.
