Do you believe in ghosts? The Appellate Division of the New York Supreme Court
Jeffrey Stambovsky bought a house from Helen Ackley. Only later did he realize that Ms. Ackley had publicized the house as being haunted. Mr. Stambovsky didn't like the idea of owning a haunted house and sought a recission of the sale in the New York Supreme Court. That Court found that Ms. Ackley didn't have a duty to disclose the haunting. The Appellate Division disagreed and, since Ms. Ackley had publicized the haunting so widely, estopped her from denying that the house was haunted. Notice that the Court held that the house is haunted as a matter of law.
This case came out in my first year of law school and I've always enjoyed it. Notice the link at the bottom of the page. It goes back to a page of silly cases that includes U.S. v. Satan
, 54 F.R.D. 282, where the Court dismissed a claim against Satan for want of jurisdiction. Pretty funny.
