Definition
A form of questioning in which the questioner, through the structure or content of the question itself, implies or communicates the desired or expected answer. The term is used in evidence law as a functional synonym for "leading question" — a question that suggests its own answer to the witness rather than leaving the witness to supply the answer independently.
In the context of evidentiary rules governing witness examination, a suggestive interrogation is generally disfavored on direct examination precisely because the questioner's influence contaminates the reliability of the response. The witness is not so much recalling a fact as confirming what the examiner has already supplied.
The phrase carries secondary relevance in modern criminal procedure, where the suggestive character of police questioning — whether during custodial interrogation or witness identification procedures — bears on the admissibility and reliability of statements and identifications obtained.

Common Confusion
Suggestive interrogation and leading question are functionally the same concept in the evidentiary sense, and the historical sources treat them as interchangeable. Researchers should not expect the two phrases to have distinct legal meanings — they do not. The confusion arises because "suggestive interrogation" appears primarily in older treatises and French legal sources, while "leading question" is the term that survived into modern Anglo-American evidence rules and contemporary practice. A researcher encountering "suggestive interrogation" in a historical source is reading the same concept under an older label.
The term should also be distinguished from the modern criminal procedure usage of "suggestive" in the context of eyewitness identifications — as in "unnecessarily suggestive" identification procedures — which is a separate doctrine with its own constitutional framework under due process, not a direct descendant of the evidentiary term.

Why It Matters in Research
The primary research trap here is temporal. "Suggestive interrogation" is a period term. It appears in nineteenth-century treatises — Bentham's Rationale of Judicial Evidence is the anchor citation in both Black's and Bouvier's — and in translations or discussions of French procedure. When it surfaces in a historical source, it signals the leading question doctrine, not anything more exotic. Researchers who encounter the phrase without this context may waste time hunting for a separate rule or doctrine that does not exist under that name.
In the Law Mind corpus, the more productive path in most research contexts runs through the leading question doctrine and, for criminal procedure questions, through the Miranda interrogation definition developed in Rhode Island v. Innis. These are the living analytical frameworks. "Suggestive interrogation" is the ancestor term, not the operative one.
The Bentham citation is worth flagging: both Black's and Bouvier's cite the same passage but with inconsistent book and chapter references (Black's gives b. 3, c. 3; Bouvier's gives b. 8, c. 8). Researchers working with the primary Bentham source should check both references rather than relying on either dictionary's citation alone.
For researchers working in comparative law or on French civil procedure, the phrase may retain independent analytical utility, as it reflects civilian evidentiary vocabulary that did not fully map onto common law equivalents.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) and Bouvier's Law Dictionary are in substantial agreement: both define suggestive interrogation as a phrase used by some writers to mean the same thing as leading question, and both anchor the usage to Bentham's treatise on judicial evidence. Both sources also note the term's use in French law, suggesting its currency was primarily continental and academic rather than embedded in Anglo-American practice.
Neither dictionary attempts a substantive elaboration of the concept beyond the cross-reference to leading question. This brevity is itself informative: by the time these dictionaries were compiled, "suggestive interrogation" was already receding from active Anglo-American legal usage, surviving mainly as a scholastic term of art. The entries read less like definitions of a working legal concept and more like glosses for the benefit of readers who had encountered the phrase in older or foreign sources.
What the historical dictionaries do not address — and what has since become a significant area of law — is the constitutional dimension of suggestive questioning in criminal investigations. The voluntariness doctrine, the Miranda framework, and the due process rules governing identification procedures all grew up outside the evidentiary tradition that produced this term.
