Liversidge v Anderson AC 206 is an important and landmark case in English law which concerned the relationship between the courts and the state, and in particular the assistance that the judiciary should give to the executive in times of national emergency. It concerns civil liberties and the separation of powers. Both the majority and dissenting judgments in the case have been cited as persuasive precedent by various countries of the Commonwealth of Nations. However, in England itself, the courts have gradually retreated from the decision in Liversidge.
