Albert Haddock is the protagonist, and alter ego of the author, in many of the fictional law reports written by A. P. Herbert for Punch magazine between 1910 and the 1950s, and also published in a number of books.
Haddock is a prodigious litigant, who attempts to highlight absurdities or contradictions in the law through either initiating court cases, or by commiting acts which result in others taking him to court, or in his being arrested and prosecuted.
A particularly well-known example of a case involving Mr Haddock is Board of Inland Revenue v Haddock, otherwise known as The Negotiable Cow. Haddock, during a dispute with the Collector of Taxes about his income tax, successfully argues that a cheque written on the abdomen of a cow is a valid cheque, and therefore the Collector, having refused to accept the cow as payment of the outstanding tax, is estopped from demanding payment by other means.
