A legal fiction, broadly, is a false assumption knowingly relied upon by the courts. The main aim of the dissertation is to formulate a test for which fictions should be accepted and which rejected. Subsidiary aims include a better understanding of the fiction as a device and of certain individual fictions, past and present. This research is undertaken, primarily, to establish a rigorous system for the treatment of fictions in English law – which is lacking. Secondarily, it is intended to settle some intractable disputes, which have plagued the scholarship. These theoretical debates have hindered progress on the practical matters which affect litigants in the real world. The dissertation is divided into four chapters. The first chapter is a historical study of common-law fictions. The conclusions drawn thereform are the foundation of the acceptance test for fictions. The second chapter deals with the theoretical problems surrounding the fiction. Chiefly, it seeks precisely to define ‘legal fiction’, a recurrent problem in the literature. A solution, in the form of a two-pronged definition, is proposed, adding an important element to the acceptance test. The third chapter analyses modern-day fictions and recommends retention or abolition for each fiction. In the fourth chapter, the findings hitherto are synthesised into a general acceptance test for fictions. This test, which is the thesis of this work, is presented as a flowchart. It is the author’s hope that this project will raise awareness as to the merits and demerits of legal fictions, de-mystify the debate and bring about reform. 9 May 2018 iii iv To Eliezer and Rivka v vi Declaration Except where specifically indicated in the text, this dissertation is the result of my own work and includes nothing which is the outcome of collaboration.

The maxim that ‘Everybody knows the law’ is an example of a legal fiction.1 As a statement of fact, the maxim is evidently false. Not even lawyers or judges know all the law. And yet, courts apply it, as if it were true, with the result that ignorance of the law is no defence.2 We therefore say that the maxim is a legal fiction.
