Attorney obtained dismissal of homeowners sued for an allegedly dangerous condition (defective staircase) even though accident occurred six months after sale to current owner. Plaintiff was a furnace repairman hired by the current owners and was injured when the stairway collapsed under him. Defendants' dismissal was granted on preliminary objections alleging no duty running to plaintiff because defendants were neither owners nor possessors of the property at the time of the accident.
