Production Versus Persuasion

Production Versus Persuasion

The preceding section established that the prosecution must prove every element of the offense beyond a reasonable doubt. That rule packs two distinct duties into the single idea of proof, and criminal problems become easier to solve once the duties are separated. One decides whether a contested issue reaches the jury at all, and the other decides who loses when the jury cannot make up its mind. On each element the prosecution carries both, which is why a defendant may sit silent through an entire trial and still be entitled to acquittal if the proof falls short.¹ Facts that are not elements follow a different allocation, taken up at the end of this section.

Burden of Production

A party bears the burden of production when, if the evidence is left as it stands, the court will decide the issue against that party as a matter of law.² For the prosecution, that means coming forward with evidence on each element from which a reasonable jury could find the element established beyond a reasonable doubt, and if the prosecution fails, the court must enter a judgment of acquittal.³ Whether the burden has been met is a question for the judge in running the trial, so the jury is never instructed about it.⁴ The standard is sufficiency: the court asks only whether some reasonable juror could find the fact, whatever the judge may personally think of the witnesses.⁵

The burden exists to keep a case without a factual basis away from the jury. If no reasonable juror could find an element, a guilty verdict would rest on speculation, so the judge removes the issue before deliberations begin. The persuasion standard sets the height of this screen. Because jurors must be convinced beyond a reasonable doubt, the judge asks whether a juror could reach that certainty, whereas in a civil case the judge asks only whether a juror could find the fact by a preponderance of the evidence.⁶ The screen also runs in one direction in a criminal case. Because the defendant has a right to trial by jury, the prosecution cannot obtain a peremptory ruling that an element is established, and a verdict of guilty may not be directed as a matter of law.⁷ Since the court cannot direct a verdict against the defendant, the burden of production on an element stays with the prosecution rather than moving to the defendant, a contrast with civil litigation, where the duty to come forward can pass from one party to the other as the evidence develops.⁸

A defendant is entitled to acquittal at the close of the prosecution's case if that evidence, even if believed, would not establish guilt beyond a reasonable doubt, which describes the gap in the first version of the robbery trial.⁹ The added eyewitness changes the answer because production asks what a reasonable juror could find. The jury's own view of the witness's credibility is left for deliberation, where a different burden takes over.

Burden of Persuasion

Once an element survives the screen and the case goes to the jury, the question changes from whether the jury may find the fact to what happens if the jurors cannot decide. The burden of persuasion answers it: it is a party's duty to convince the fact-finder, and the party who bears it loses the issue if the jury is not convinced to the required degree.¹⁰ One way to picture the idea is a switch that rests in one position and moves to the other only when enough force is applied. The jury is told to resolve each issue in a stated way unless it is convinced to a given degree that the answer is the other way, and the party who loses if the switch stays put carries the burden.¹¹ On the elements of a crime, the switch rests at not proved, the prosecution must move it, and the force required is proof beyond a reasonable doubt of every fact necessary to constitute the crime.¹²

The height of that standard is easiest to see against its civil counterpart. A belief that guilt is slightly more probable than not falls short in a criminal case, yet the same belief could carry a verdict in an analogous civil suit, where the burden is a preponderance of the evidence.¹³ Evidence in equipoise, or evenly balanced, leaves the party with the burden the loser on that issue.¹⁴ Placing the persuasion burden on the prosecution and fixing it high therefore decides whom the system's mistakes will favor. A jury that is genuinely torn must still resolve the issue, and the rule resolves it for the accused, which serves the purpose of the standard: reducing the risk of convictions that rest on factual error.¹⁵

The two burdens also behave differently over the course of a trial. The duty to produce evidence on an issue can move among the parties, while the duty to persuade remains with the party on whom it first rests. For elements, both stay with the prosecution from start to finish. Because the prosecution holds the burden on every essential element, the defense is not required to present any evidence.¹⁶ The defendant need not take the stand either, and the prosecutor may not argue or suggest that a failure to testify indicates guilt.¹⁷

The burglary example separates the two burdens cleanly. Production was met, since the case reached the jury, and persuasion was not, since the jury was unconvinced to the required degree. Students lose this issue when they let the defense's decision to offer nothing stand in for proof, because silence neither fills a gap in the prosecution's case nor shifts any burden onto the accused.

Facts Outside the Elements

Not every fact that matters in a criminal case is an element. Sometimes a provision of the Model Penal Code applies only if a court or jury finds a fact that forms no part of the definition of the offense, and for those facts the Code sets its own allocation, unless it provides otherwise.¹⁹ The burden of proving such a fact rests on the prosecution or the defendant, depending on whose interest or contention the finding would further.²⁰ The fact must be proved to the satisfaction of the court or jury, as the case may be, a measure that does not carry the reasonable-doubt requirement that governs elements.²¹

Each half of the rule has its own logic. Tying the burden to the party who gains from the finding places the work of proof with the side that wants the fact established and is usually best placed to supply the evidence, and it avoids forcing a party to prove a fact whose only effect is to help the opponent. The lighter measure follows from what the reasonable-doubt standard protects. That standard attaches to the facts necessary to constitute the crime, because those facts decide whether the conduct is criminal at all, and an error about them produces a conviction that should not exist.²² A fact outside the definition of the offense does not decide that question, so the Code does not apply the strictest standard in the law to it.

The allocation turns on interest, so it reverses when the prosecution is the side whose contention the finding would advance. Set this example beside the burglary trial above and the difference comes from classification. Identity is an element, so the prosecution carries production and persuasion to the reasonable-doubt standard, while completion of treatment is outside the elements, so the burden follows the party who benefits and the measure drops to the satisfaction of the factfinder. Students lose this issue when they demand proof beyond a reasonable doubt for a fact that is not an element, or when they assign the prosecution a burden the Code places on the party the finding would help. Defenses add their own rules, taken up below.

This allocation assumes that the line between element and non-element is already drawn, and that line is not entirely within a legislature's control. Government may allocate the burdens of production and persuasion unless it offends a principle of justice so rooted in tradition as to be fundamental, but once it defines a crime it must prove each element as defined beyond a reasonable doubt, and it may not move the burden of persuasion onto the defendant by means of a presumption.²³ How far a legislature may go in placing persuasion burdens on the accused is the question the next section takes up.
