Trespass §§ 86–89.]“In trespass, whether to person or property, the general issue is ‘not guilty.’ It operates in the first place as a denial that the defendant committed the act of trespass alleged, to wit, the application of force to the plaintiff’s person, the entry on his land, or the taking or damages of his goods. It also denies the plaintiff’s possession, title, or right of possession of the land or goods.” Benjamin J. Shipman, Handbook of Common-Law Pleading § 170, at 307–08 (Henry Winthrop Ballantine ed., 3d ed. 1923).

not guilty by statute.Hist. Under certain acts of Parliament, the pleading form for a defendant’s general denial in a civil action. • This pleading form allowed a public officer to indicate action under a statute. The officer had to write the words “by statute” in the margin along with the year, chapter, and section of the applicable statute, and the defendant could not file any other defense without leave of court. The right to plead “not guilty by statute” was essentially removed by the Public Authorities Protection Act of 1893.

4. A general denial in an ejectment action. [Cases: Ejectment 68.C.J.S. Ejectment §§ 63–64.]“The general issue in ejectment is not guilty.

(2) All defenses in excuse or discharge, including the statute of limitations, are available under the general issue in ejectment.” Benjamin J. Shipman, Handbook of Common-Law Pleading § 188, at 333 (Henry Winthrop Ballantine ed., 3d ed. 1923).
