Definition
A disjunctive allegation is a statement in a pleading or indictment that charges a fact, act, or element in the alternative, using the conjunction "or" to connect two or more possibilities. Rather than asserting a single, definite act or circumstance, a disjunctive allegation leaves open which of two or more alternatives is being charged or relied upon.
The classic illustration: an indictment charging that the defendant "murdered, or caused to be murdered" a named victim states the offense disjunctively. The pleader has not committed to one theory but has instead embedded an either/or choice within the charging instrument itself.
Disjunctive allegations are generally disfavored in criminal pleading because they may render an indictment or information fatally defective for vagueness — the defendant is not given adequate notice of the specific act or theory against which a defense must be prepared. In civil pleading, the rules governing disjunctive allegations vary by context and procedural regime. Modern pleading codes and rules differ from the strict common law pleading standards under which the doctrine was most rigorously applied.
Common Confusion
DISJUNCTIVE ALLEGATION vs. ALTERNATIVE PLEADING: These concepts are related but not identical, and the distinction matters for research. Alternative pleading (permitted under modern rules such as Federal Rule of Civil Procedure 8(d)) allows a party to plead multiple, even inconsistent, claims or defenses in separate counts. A disjunctive allegation, by contrast, embeds the alternatives within a single charge or count using "or," leaving the charge itself internally ambiguous. Alternative pleading is broadly permitted; disjunctive allegations, particularly in criminal indictments, are traditionally suspect or defective.
DISJUNCTIVE vs. CONJUNCTIVE ALLEGATION: A conjunctive allegation charges two or more acts together using "and," requiring proof of each. A disjunctive allegation charges acts in the alternative using "or," requiring proof of only one — but also giving the defendant less certainty about what is actually charged. Understanding this pairing is essential for reading historical pleading treatises and case law on indictment sufficiency.
Why It Matters in Research
This term appears most prominently in two research contexts: criminal pleading (indictment sufficiency) and the history of common law pleading doctrine.
In criminal law research, the disjunctive allegation doctrine surfaces whenever courts assess whether an indictment provides constitutionally adequate notice of the charges. An indictment that tracks the disjunctive language of a statute (e.g., "the defendant did A or B") has historically been held defective because the defendant cannot know which act is alleged. Researchers working through 19th and early 20th century appellate decisions will find extensive treatment of this problem, particularly in courts applying strict common law pleading standards to criminal informations and grand jury indictments.
A key navigational trap: modern courts in many jurisdictions have partially relaxed this rule when a criminal statute itself is written disjunctively. Some courts permit the indictment to track statutory language and charge multiple disjunctive means in a single count, particularly where the acts charged are merely different means of committing the same offense. Research must account for this evolution — a statement that disjunctive allegations are "always" defective reflects pre-20th century doctrine and does not hold universally today.
In civil pleading research, the term appears less frequently after the adoption of code pleading and later notice pleading regimes, which liberalized the rules governing alternative and disjunctive statements. Researchers working in equity or early common law pleading contexts will encounter the doctrine more intensively.
Jurisdictional variation is significant. State courts applying their own constitutional pleading requirements for indictments may reach different outcomes than federal courts. Researchers should not assume that a ruling on disjunctive allegation defects from one jurisdiction translates directly to another.
This term connects directly to broader research on pleading sufficiency, bill of particulars practice (often the procedural remedy when an indictment is disjunctive but not dismissed outright), and the constitutional right to notice of charges.
Historical Dictionary Support
Black's Law Dictionary supplies the foundational definition: a statement in a pleading or indictment that expresses or charges a thing alternatively with the conjunction "or," illustrating with the example of a charge that a defendant "murdered, or caused to be murdered." This entry is serviceable but minimal. It captures the structural feature of the term — the use of "or" — without addressing the legal consequences that flow from it.
What the historical dictionary entry omits is significant: it does not address whether such an allegation is permissible, defective, or context-dependent. Researchers relying solely on Black's historical entry would have the form of the concept but not its legal weight. The entry also does not distinguish between civil and criminal contexts, nor does it note the relationship to common law pleading rules requiring certainty in criminal charges. This gap is characteristic of Black's treatment of pleading terms across its earlier editions, which tend to define structure rather than analyze consequences.
No meaningful divergence exists across the available source dictionaries because only one source is represented here, but researchers should consult pleading treatises — particularly those addressing indictment practice — for the doctrinal development that dictionary entries of this era do not provide.
Jurisdictional Note
The consequences of a disjunctive allegation in a criminal indictment vary by jurisdiction. Some states have codified rules permitting disjunctive charging when the alternatives represent different means of committing a single statutory offense. Federal practice under the Federal Rules of Criminal Procedure has generally permitted charging in the conjunctive even when a statute is written disjunctively, avoiding the problem through drafting convention. Researchers should identify the governing pleading rules and constitutional notice standards of the specific jurisdiction before drawing conclusions.
