A service member is questioned, gives a statement, and only afterward does it become clear that the first questioner failed to give a proper Article 31 advisement. Later, a different investigator questions the member again, this time with warnings, and obtains a second statement. The defense naturally asks whether the first investigator’s error poisons the second statement. The answer is that it can matter, but it does not automatically taint what comes later. Military law evaluates the second statement on its own terms under a totality-of-the-circumstances analysis.
The starting point: an unwarned statement is excludable
Article 31(b) of the Uniform Code of Military Justice requires that a service member suspected of an offense be advised, before questioning by a person acting in an official disciplinary or law-enforcement capacity, of the nature of the accusation, of the right to remain silent, and that any statement may be used at trial. When a questioner who owed that advisement fails to give it, the resulting statement is generally inadmissible. Article 31(d) bars use of statements taken in violation of the article, and Military Rule of Evidence 304 governs suppression of unwarned or involuntary statements.
The harder question is what happens to a later statement, taken by someone else, after the first error.
The controlling military rule on successive statements
The Court of Appeals for the Armed Forces addressed this in United States v. Brisbane, 63 M.J. 106 (C.A.A.F. 2006). The court held that where an earlier statement was involuntary only because the accused had not been properly warned of Article 31(b) rights, the voluntariness and admissibility of a second statement are determined by the totality of the circumstances. The earlier unwarned statement is a factor in that total picture, but it does not presumptively taint the later statement. In other words, there is no automatic rule that one investigator’s failure to warn invalidates everything that follows.
This military approach parallels the Supreme Court’s civilian reasoning in Oregon v. Elstad, 470 U.S. 298 (1985), which held that in a two-stage interrogation, where an initial unwarned statement was voluntary, a later statement taken after proper warnings is admissible so long as the later statement is also voluntary. The simple failure to warn the first time does not, by itself, brand the second confession as the fruit of the first.
The role of a cleansing warning
Brisbane also addressed the so-called cleansing warning, which is an …
