A Treatise of Pleas of the Crown; or, a system of the principal matters relating to that subject, digested under proper heads (or Pleas of the Crown for short), is an influential[1] treatise on the criminal law of England, written by William Hawkins, serjeant-at-law, and later edited by John Curwood, barrister.
In 1847, John Gage Marvin said: "There are very few juridical writers, whose compilations are more full of useful knowledge, or more methodically digested, even down to the minute sub-divisions, than the Pleas of the Crown, by Mr. Serj.
In this admired and authoritative work the student will readily find information in almost every point of Law relating to Crimes and Punishments."
Mr. Curwood cut off "some of Leach's excrescences," and added a good selection of leading Cases, rarely referring to the rulings of a single judge.
[4]In 1925, Percy Henry Winfield said: "In his preface, Hawkins, after a panegyric on the existing criminal law which staggers any modern lawyer accustomed to something less brutal, points out the imperfections of previous attempts to expound it, and states his own object to be the reduction of all the laws relating to it under one scheme.
On historical points, it occasionally requires verification, and in the editions, which we have used, it is often overloaded with marginal references, some of which are untraceable and others worthless; but it may be that these are due to later editors.
It was the starting-point of modern laborious treatises on the criminal law which are valuable as digests of the subject, but which make no advance on Hawkins’s plan or style, and are not invariably reliable on matters of history.
