Definition
In English ecclesiastical law, a defensive allegation is a form of pleading by which a defendant, rather than simply denying the plaintiff's charge under oath, affirmatively sets forth circumstances in his defense. The effect is procedurally significant: by making a defensive allegation, the defendant acquires the right to demand the plaintiff's sworn answer to those defensive circumstances, after which the defendant may proceed to proofs just as the plaintiff may on his own allegations.
The term belongs almost exclusively to the practice of the ecclesiastical courts of England — tribunals that operated under canon law and civilian procedure rather than the common law forms of action. In that system, pleading by allegation (rather than by common law declaration and plea) was standard, and the defensive allegation was the defendant's affirmative response within that framework.

Common Confusion
DEFENSIVE ALLEGATION should not be confused with a general denial or a demurrer. A general denial simply contradicts the plaintiff's charge; it does not introduce new matter and does not entitle the defendant to compel the plaintiff's oath on any new point. A demurrer admits the facts for purposes of argument and contests only their legal sufficiency. The defensive allegation is distinct in that it introduces new affirmative circumstances and triggers a reciprocal obligation on the plaintiff to answer under oath — a mechanism native to civilian procedure and without a direct analogue in common law pleading.
It also should not be conflated with a modern affirmative defense in civil practice, though the underlying logic — asserting new matter to avoid liability rather than merely denying the charge — is conceptually similar.

Why It Matters in Research
DEFENSIVE ALLEGATION is a term of art from English ecclesiastical court practice and will appear almost exclusively in historical sources dealing with that jurisdiction: treatises on ecclesiastical procedure, canon law commentaries, and cases decided in the ecclesiastical courts before their jurisdiction was consolidated and ultimately reduced by the Judicature Acts of the nineteenth century. Researchers will not encounter this term in American case law or statutes, and it carries no operative meaning in modern common law civil procedure.
The key navigational point is the procedural consequence. When historical sources describe a defensive allegation, the significant outcome is not merely that the defendant has responded — it is that this particular form of response shifts the procedural dynamic by compelling the plaintiff's sworn answer. Researchers reading ecclesiastical proceedings who encounter this term should attend to what follows it: the plaintiff's responsive oath and the opening of proofs on the defensive matter.
For researchers using Blackstone as a source, note that both Burrill and Black cite to 3 Bl. Comm. 100, placing this term in Blackstone's discussion of the proceedings of the ecclesiastical courts. Bouvier cites 8 Bla. Com. 100, which appears to be a different edition's pagination for related material. The Burrill entry also cites Halifax's Analysis of the Civil Law, a useful pointer for researchers needing to understand the civilian procedural tradition from which this practice derives.
The term has no surviving practical relevance in American law and limited relevance in modern English law, but it is essential vocabulary for anyone researching church court records, probate matters adjudicated in ecclesiastical forums (wills and matrimonial causes were long within their jurisdiction), and the history of pleading.

Historical Dictionary Support
Bouvier, Burrill, and Black are in close agreement on the substance, with Bouvier offering the most compressed treatment and Burrill and Black providing the fuller procedural context drawn directly from Blackstone. All three sources agree on the defining feature: the defendant is not merely denying but affirmatively alleging circumstances, and the consequence is the right to the plaintiff's sworn answer and a full proofs phase.
Burrill's entry is the most complete, adding the Halifax citation alongside Blackstone and Stephen, which situates the practice within the broader civilian tradition rather than treating it as a purely English ecclesiastical peculiarity. Blackstone's own account (as reflected in all three dictionaries) is the foundational source for this term in the English legal literature.
What none of the historical dictionaries address is the practical mechanics of how the defensive allegation interacted with the libel (the plaintiff's initiating pleading in ecclesiastical proceedings) or what happened when the plaintiff refused or was unable to answer the defensive matter under oath. Researchers needing that level of procedural detail will need to go beyond these dictionary sources to Oughton's Ordo Judiciorum or similar ecclesiastical practice manuals.

Jurisdictional Note
This term is specific to the historical ecclesiastical courts of England and has no direct counterpart in American legal practice. It does not appear in the practice of any American jurisdiction. Researchers working on colonial American records involving church courts (primarily Anglican contexts in the southern colonies) may encounter the terminology, but its practical application in America was limited and largely derived from English ecclesiastical forms.
