From the real-life Stambovsky v. Ackley case, as mentioned by the judge:
While I agree with Supreme Court that the real estate broker, as agent for the seller, is under no duty to disclose to a potential buyer the phantasmal reputation of the premises and that, in his pursuit of a legal remedy for fraudulent misrepresentation against the seller, plaintiff hasn't a ghost of a chance, I am nevertheless moved by the spirit of equity to allow the buyer to seek rescission of the contract of sale and recovery of his down payment...From the perspective of a person in the position of plaintiff herein, a very practical problem arises with respect to the discovery of a paranormal phenomenon: "Who you gonna call?" as a title song to the movie "Ghostbusters" asks. Applying the strict rule of caveat emptor to a contract involving a house possessed by poltergeists conjures up visions of a psychic or medium routinely accompanying the structural engineer and Terminix man on an inspection of every home subject to a contract of sale. It portends that the prudent attorney will establish an escrow account lest the subject of the transaction come back to haunt him and his client — or pray that his malpractice insurance coverage extends to supernatural disasters. In the interest of avoiding such untenable consequences, the notion that a haunting is a condition which can and should be ascertained upon reasonable inspection of the premises is a hobgoblin which should be exorcised from the body of legal precedent and laid quietly to rest.
