Diplock LJ:… A cause of action is simply a factual situation the existence of which entitles one person to obtain from the court a remedy against another person. Historically, the means by which the remedy was obtained varied with the nature of the factual situation and causes of action were divided into categories according to the ‘form of action’ by which the remedy was obtained in the particular kind of factual situation which constituted the cause of action. But that is legal history, not current law… The Judicature Act 1873 abolished forms of action. It did not affect causes of action; so it was convenient for lawyers and legislators to continue to use, to describe the various categories of factual situations which entitle one person to obtain from the court a remedy against another, the names of the various ‘forms of action’ by which formerly the remedy appropriate to the particular category of factual situation was obtained. But it is essential to realise that when, since 1873, the name of a form of action is used to identify a cause of action, it is used as a convenient and succinct description of a particular category of factual situation which entitles one person to obtain from the court a remedy against another person.
