Harry is selling a magic wand to Draco. When Draco asks about the wand, Harry says, "I don't know for sure, but Dumbledore told me it was the Elder Wand" (assume Harry is telling the truth). Draco, eager to own the Elder Wand, relies on this statement from Harry and purchases the wand for a lot of money. Draco later finds out that the wand is not the Elder Wand and is basically worthless, and sues Harry for fraud. Who wins?
