I Lon Fuller’s The Case of the Speluncean Explorers is a hypothetical case, a thought experiment composed of perfect scenarios presenting jurisprudence of different schools. The 14 judges argue against each other with various legal grounds to acquit or convict the defendants. Their disputes dominantly focus on three points. The first issue is whether or not a judge should discriminately apply the letters of the law, and whether or not discretion is allowed in order to achieve legal purpose. Then comes to the dispute about if contract theory can stand in this case and how this contract should be understood.
