Burden-Shifting Argument

What it is

Argument or questioning that implies the party without the burden of proof must explain, prove, or disprove something: commenting on a criminal defendant's silence, asking why the defense called no witnesses, or demanding that a witness say whether the police officers were lying.

How it works

The burden of proof is the law's allocation of doubt, and burden-shifting reassigns it. In a criminal case the prosecution must prove every element beyond a reasonable doubt and the defendant need prove nothing; a prosecutor who asks "if he were innocent, why did he not tell the police?" invites the jury to treat the absence of a defense case as proof of guilt. The move works because ordinary conversation treats silence as concession and because jurors prefer a two-sided contest to a one-sided test. Griffin v. California (1965) holds that comment on a defendant's failure to testify violates the Fifth Amendment, and Doyle v. Ohio (1976) bars using post-Miranda silence for impeachment. A subtler form is the "were they lying?" question, which forces a witness to accuse others and implies the jury must choose between two witnesses rather than ask whether the state proved its case; many appellate courts condemn it. Civil burdens are lighter and shift lawfully in places (affirmative defenses, presumptions), which is why the instruction on who must prove what is read to the jury and why misstating it is error.

Real-world examples

  • •Griffin v. California (1965): the prosecutor argued that the defendant, who did not testify, was the one person who could explain the evidence and had chosen not to; the Supreme Court held that such comment penalizes the constitutional right to remain silent.
  • •Doyle v. Ohio (1976): prosecutors impeached defendants by asking why they had not told their exculpatory story to police at arrest; the Court held that silence after Miranda warnings cannot be used this way, because the warnings implicitly promise it will not be.
  • •The "were the officers lying?" question, put to a testifying defendant, is condemned in many federal circuits and states because it misstates the jury's task and forces a witness to call others liars, though some courts allow it where the defense itself has argued fabrication.
  • •In civil trials burden-shifting appears as "the defendant has not shown you any other reason this happened" in a case where the plaintiff bears the burden on causation; the cure is an objection and a reread of the burden instruction.

Ethical guidelines

  • ●Commenting on a criminal defendant's silence or failure to present evidence is prohibited; prosecutors who do so risk reversal and, for repeated conduct, discipline under Model Rules 3.8 and 8.4(d).
  • ●It is legitimate to argue that evidence is unrebutted where the defense chose to contest the point, and to comment on a defense witness who did testify; the line is any suggestion that the defendant had to prove something.
  • ●Defense lawyers may not misstate the burden in the other direction either, for example by suggesting the state must prove guilt beyond all possible doubt; misstatements of the standard by either side draw objection and correction.
  • ●Educational; rules vary by jurisdiction; not legal advice.

How to defend against it

  • ►Jurors: keep the burden instruction in front of you during deliberation and, whenever someone says "but he never explained", reread it; in a criminal case the absence of a defense case is not evidence of anything.
  • ►Jurors: reframe "which witness do you believe?" as "has the party with the burden proved this element to the required standard?"; the two questions have different answers more often than intuition suggests.
  • ►Opposing advocates: object immediately, request a curative instruction that restates the burden, and in a criminal case move for a mistrial where the comment goes to the defendant's silence; in closing, make the burden instruction the structure of your argument.
  • ►Witnesses: if asked whether another witness was lying, answer only what you know ("I can only tell you what I saw"); you are not required to characterize anyone else's honesty.

(Educational; the rules vary by jurisdiction.)
