Principal finding

A sea fort sunk on a sandbank in 1942, and held by one family since 1966, is sound as a structure and unrecognised as a state, and its titles are keenly priced. The Trebuchet Research Group’s application is refused. The fort has not moved. Neither has the Government. The border has.

The fort, its history, the court case, the events of 1978, the law, the prices and the three comparison territories are real and referenced, among them an interview with Michael and Liam Bates published this month. The College, the Trebuchet Group’s application and every finding are fiction. The Bates family are real people, and the paper’s humour is at the expense of the law, the price list and the College, not theirs.
