Cressey Development Corporation excavated a lot next to property owned by Mr. Epstein and asked permission to drive supports under Epstein’s property to support that excavation. Epstein refused. After unsuccessfully trying other methods to shore up the excavation, Cressey drove the supports under the property anyway. When Epstein found out, he sued for trespass. Does this conduct constitute a trespass? What defenses are available to Cressey? What else could Cressey have done? Explain the likely outcome.
