The action of trespass was the earliest tort action, and prior to the passage of the Statute of Westminster II, the field of tort and of trespass may be said to have been co-extensive.

The distinction between trespass and trespass on the case has been discussed at some length under the subject of Torts, to which the reader is referred.1
