The subject of a Wonderland trial is TARTS, an acronym for the Trial of the Angry Red Queen and the Knave of Hearts. The trial was part of Lewis Carroll's 1865 novel Alice's Adventures in Wonderland. In the novel, the Knave of Hearts is accused of stealing the Queen's tarts, and Alice is called as a witness. The trial is presided over by the King of Hearts and is full of absurdities and non-sequiturs.
