The Disclosure Floor: Evidence the State Must Share

Other constitutional protections ask whether the prosecution withheld favorable evidence, used an identification procedure that created an unacceptable risk of mistake, or submitted a serious criminal charge to an impartial and constitutionally sufficient jury. The governing law is the US Constitution only. A prompt becomes live when it mentions a police file not given to the defense, a late disclosure, a witness deal, inconsistent statements, a lineup or showup, a one-photo procedure, a tainted in-court identification, a serious offense, jury size, nonunanimity, or a biased juror.

You are not required to hold this topic cold because resources may be supplied; the floor you must hold in memory is the vocabulary and sequence: favorable evidence, prosecution possession, suppression, materiality, suggestiveness, necessity, reliability, totality of circumstances, serious offense, jury size, unanimity, and impartiality. You need not hold exact element wording, exception lists, or numbered subsections. This topic is not starred: legal resources may be supplied when it is tested, and where they are not, you need only demonstrate recognition that the topic is at issue.

The Brady disclosure rule covers both exculpatory evidence and impeachment evidence. Favorable evidence may negate an element, support an affirmative defense, undermine a prosecution witness, reveal a deal or benefit, or show that an identification was less reliable than the witness claims. Impeachment material is not outside the rule merely because it does not directly prove innocence.

Ask whether the evidence was in the prosecution’s possession or control. The prosecution team ordinarily includes investigating police, so a prosecutor cannot avoid the rule by saying that the information was in a police report the prosecutor did not personally read. The evidence must also be sufficiently connected to the prosecution’s case. Information already known to the defendant or equally available through ordinary defense investigation is less likely to count as suppressed.

Suppression does not require bad faith. An intentional failure and an inadvertent failure can both create a constitutional problem. Timing matters: disclosure must occur early enough for meaningful use. Disclosure after the defense has lost the opportunity to investigate, cross-examine, subpoena a witness, or adjust its theory may be too late even if the material is technically disclosed before the verdict.

Materiality is the decisive question. Ask whether timely disclosure creates a reasonable probability of a different result, meaning a probability sufficient to undermine confidence in the verdict. Do not ask whether the evidence would certainly produce acquittal. Consider the item’s individual force, its impeachment value, and its cumulative significance together with other undisclosed favorable evidence. A weak item can become material when combined with another weakness in the prosecution’s case. If there is no reasonable probability of a different result after that review, the nondisclosure is harmless.

The practical remedies are disclosure, a continuance, reopening an examination, or a new trial when the late or missing evidence was material. The evidence is not automatically excluded merely because it was withheld; the constitutional injury is the unfair loss of a meaningful opportunity to use favorable evidence. A material nondisclosure may require reversal or a new trial.

Read a supplied provision by locating its operative verbs first: “must disclose,” “in possession,” “before trial,” “effective use,” and “reasonable probability.” Then identify exceptions or limiting phrases, and map each fact to one phrase. Do not decide materiality before deciding favorability, possession, and suppression.

Faces, Procedures, Reliability: When Identification Becomes Unfair

Due process regulates identification procedures arranged by the police. First ask whether the procedure was suggestive. A lineup can be suggestive if fillers differ materially from the suspect, the administrator cues the witness, or the suspect is singled out. A showup presents one detained person and therefore carries a substantial suggestive risk. A photographic array can be suggestive if one photograph stands out, the officer signals the suspect, or the witness is shown only one photograph. An in-court identification is inherently focused on the defendant, so the central question is often whether an earlier improper procedure tainted it.

Suggestiveness does not automatically require exclusion. The next questions are whether the procedure was unnecessarily suggestive and, if so, whether the identification remains reliable under the totality of the circumstances. Necessity may matter especially with a showup: immediate confirmation near the scene may justify a single-person procedure, while a showup conducted later when a fair lineup was feasible is harder to justify.

Reliability is fact-specific. Consider the witness’s opportunity to view the perpetrator, degree of attention, accuracy of the description before seeing the suspect, level of certainty at the challenged procedure, and time between the event and the identification. Confidence expressed after police encouragement receives less weight. The court balances the reliability circumstances against the suggestive influence rather than treating any one factor as conclusive.

Identification procedureMain suggestiveness questionMain reliability questionPossible consequence
LineupDid fillers, instructions, or administrator conduct make the suspect stand out?Did the witness observe the perpetrator well and identify without cueing?Reliable identification may be admitted; an unnecessarily suggestive and unreliable one may be excluded
ShowupWas a single detained person presented when necessity did not justify it?How strong were opportunity, attention, description, certainty, and timing?Suggestiveness alone is insufficient; unreliability can require exclusion
Photographic arrayDid one photo stand out or did police steer the witness?Was the witness’s selection independent and based on a sound prior observation?A fair array is ordinarily admissible; a tainted unreliable selection may be excluded
In-court identificationWas it the product of a suggestive earlier procedure?Is there a reliable basis independent of the tainted procedure?The court may permit or exclude the in-court identification depending on totality and independent reliability

If the procedure is unnecessarily suggestive but the totality shows strong reliability, the identification may still be admitted. If the procedure is suggestive and the reliability factors are weak, exclusion is the likely consequence. Keep the two conclusions separate: “suggestive” describes the police procedure; “reliable” describes the identification’s trustworthiness.

The Jury Guarantee: Serious Charges and an Impartial Decision-Maker

The Sixth Amendment protects a jury trial in a criminal prosecution, and the protection applies to state prosecutions through the Fourteenth Amendment. The constitutional jury right generally turns on whether the offense is serious or petty.

An offense carrying a maximum authorized imprisonment of more than six months is serious and requires a jury. An offense carrying a maximum of six months or less is presumptively petty. That presumption can be affected by additional statutory penalties or other objective indications that the legislature treated the offense as serious. Use the authorized maximum, not the sentence actually imposed in the particular case.

The Constitution does not require twelve jurors. A six-person criminal jury can satisfy the constitutional size requirement, while a five-person jury is constitutionally insufficient. Thus, a six-person jury is not automatically defective merely because the traditional jury has twelve members.

A constitutionally required criminal jury must be unanimous. The requirement applies in both federal and state criminal prosecutions. A verdict is therefore defective when the jurors split on guilt and the law accepts a nonunanimous guilty verdict. Unanimity is distinct from the number of jurors: six unanimous jurors can satisfy the constitutional floor, while twelve nonunanimous jurors cannot.

Impartiality means that each juror can decide from the evidence and governing law rather than from personal bias, a fixed opinion, a relationship with a participant, a financial interest, or an outside influence. A juror who cannot set aside a firm view of guilt should be removed for cause. The Constitution also protects the fairness of the jury pool, but a claim that the venire is unrepresentative is different from proof that the particular jurors who decided the case were biased.

Run the jury questions in this order:

  1. Identify the charged offense and its authorized maximum punishment.

  2. Decide whether the offense is serious or presumptively petty, accounting for objective additional penalties.

  3. If a jury is required, check whether the jury had a constitutionally sufficient number of members.

  4. Check whether the guilty verdict was unanimous.

  5. Check for actual bias, fixed opinions, relationships, or outside influence affecting a deciding juror.

When a Verdict Meets the Constitution: Separate Defects, Combined Consequences

Work a mixed fact pattern by separating the constitutional inquiries:

  1. For disclosure, identify favorable evidence, prosecution possession, suppression, timing, and materiality.

  2. For identification, identify the procedure, test suggestiveness and necessity, then assess reliability under the totality of circumstances.

  3. For the jury, classify the offense, check size and unanimity, and examine impartiality.

  4. Treat each defect independently before asking whether several weaknesses together undermine confidence in the verdict.

  5. Match the consequence to the defect: disclosure or a new trial for material Brady nondisclosure, exclusion or admission of an identification based on suggestiveness and reliability, and a new trial when a required jury was constitutionally defective.

The prosecutor charged Dana with robbery. Before trial, the prosecutor received a police report stating that eyewitness Lee initially said the robber had a large facial scar and wore a blue jacket. Dana had no scar and wore a red jacket. The report also recorded that police promised Lee $500 for information leading to a conviction.

The prosecutor did not disclose the report until after all evidence had been presented. The prosecution’s only identification evidence was Lee’s testimony. A surveillance video was too blurry to show the robber’s face.

Twenty-five minutes after the robbery, police placed Dana, handcuffed, alone beside a police car. An officer told Lee, “We caught the robber.” Lee had viewed the robber for about ten seconds in poor lighting while frightened. Lee hesitated and said, “Probably him.” Three similar people were available, and there was no urgent reason to use a showup instead of a lineup.

For this question, the supplied provision states:

“Favorable evidence includes evidence tending to negate guilt and evidence useful to impeach a prosecution witness.

Evidence is suppressed when the prosecution fails to disclose it before trial in time for effective use, whether intentionally or inadvertently.

Suppressed favorable evidence is material if, considering its individual and cumulative significance, there is a reasonable probability that timely disclosure would have changed the result.

A pretrial identification must be excluded if police used an unnecessarily suggestive procedure and the identification is not reliable under the totality of the circumstances. Reliability includes the witness’s opportunity, attention, accuracy of description, certainty, and the time between the event and identification.”

Practice

Select two conclusions that are best supported by the supplied provision.

(A) The report is not favorable because it contains impeachment evidence rather than direct proof of innocence.(B) The report supports a material Brady violation because it was favorable, in prosecution possession, withheld too late for effective use, and significant individually and cumulatively.(C) Lee’s identification is admissible because a showup is never unnecessarily suggestive.(D) Lee’s identification should be excluded because the showup was unnecessarily suggestive and the totality does not establish reliability.(E) Lee’s identification must be excluded solely because every showup is unconstitutional.(F) There is no Brady violation because the prosecutor’s failure to disclose was inadvertent.
Your answers

A six-month maximum misdemeanor has no additional statutory penalty and is tried to a judge over the defendant’s objection. The Constitution does not require a jury because the offense is presumptively petty at six months or less.

Common errors arise from concrete misreadings:

  • Treating the police report as immaterial because the prosecution still has other evidence ignores that Lee is the only identifying witness.

  • Treating impeachment as outside Brady ignores the report’s reward promise and the supplied definition of favorable evidence.

  • Treating disclosure after the evidence closes as timely ignores the lost opportunity for effective cross-examination.

  • Treating a showup as automatically unconstitutional ignores the separate necessity and reliability inquiries.

  • Relying only on Lee’s eventual certainty ignores the poor lighting, inaccurate description, hesitation, and police cue.

  • Assuming twelve jurors are constitutionally mandatory ignores that six can be sufficient.

  • Assuming every offense labeled a misdemeanor is petty ignores the authorized maximum and additional statutory penalties.

  • Accepting a nonunanimous guilty verdict in a serious prosecution ignores unanimity as a separate constitutional requirement.

A standalone multiple-choice question may isolate materiality, showup reliability, jury size, or unanimity. An integrated question set may combine a disclosure defect with an identification or jury-impartiality problem and require separate conclusions. A performance task may require you to organize the facts, use supplied constitutional authorities, and recommend a remedy without collapsing distinct tests.

High-Yield Points - ⚡ Biggest Takeaways

Brady materiality asks whether timely disclosure creates a reasonable probability of a different result individually or cumulatively. An unnecessarily suggestive identification is excluded only when totality circumstances makes it unreliable. Serious offenses require a jury and unanimous verdict. Six jurors can satisfy the constitutional size floor, but five cannot. Jurors must decide from evidence and law without actual bias or outside influence.

              • 7. A client planned to enter a closed pharmacy at night and steal prescription drugs. He asked an acquaintance to serve as lookout, but the acquaintance refused and contacted police. Unaware of that call, the client went to the pharmacy carrying burglary tools, pried open an exterior window, and began climbing through it. He then saw that the pharmacy shelves were empty because the business had permanently relocated. The client climbed down, repaired the window as well as he could, returned the tools to his garage, and went home. Police arrested him based on the acquaintance’s report and surveillance footage. The jurisdiction follows the substantial-step test for attempt and recognizes abandonment only if it is both complete and voluntary. Which of the following is the strongest conclusion?

                • A. The client completed attempted burglary because he intended the crime and took a substantial step by forcing the window.
                • B. The client avoided attempt liability because he abandoned the plan before entering and returned the tools voluntarily.
                • C. The client committed solicitation rather than attempt because he asked another person to help with the burglary.
                • D. The client committed no inchoate offense because factual impossibility prevented completion of the intended burglary.
                Show answer

                Answer: A. The client completed attempted burglary because he intended the crime and took a substantial step by forcing the window.

                The client completed attempted burglary because he intended the crime and took a substantial step by forcing the window. - He intended to enter the closed pharmacy to steal drugs, and bringing burglary tools, prying open the window, and beginning to climb through strongly corroborated that intent. - His withdrawal followed the discovery that the shelves were empty, so it was not voluntary abandonment under the jurisdiction’s rule. The client avoided attempt liability because he abandoned the plan before entering and returned the tools voluntarily. - Attempt liability arose when he took a substantial step toward the intended burglary; entering the pharmacy was not required. - Repairing the window and returning the tools did not make his withdrawal voluntary because he stopped after discovering the drugs were unavailable. The client committed solicitation rather than attempt because he asked another person to help with the burglary. - Asking the acquaintance to serve as lookout may support solicitation, even though the acquaintance refused. - That earlier request does not displace the separate attempt established when the client forced the pharmacy window. The client committed no inchoate offense because factual impossibility prevented completion of the intended burglary. - The empty shelves meant the client could not steal the drugs he expected, but factual impossibility is not a defense to attempt. - His intent and substantial step existed before he discovered that the pharmacy had relocated.

              • 8. During an argument, a driver intentionally struck a pedestrian with his car, causing severe internal injuries. At the hospital, physicians told the pedestrian that immediate surgery offered a 90% chance of survival. The pedestrian refused surgery because of a sincere fear of anesthesia. The physicians provided appropriate nonsurgical care, but the pedestrian died two days later from the injuries. The jurisdiction defines murder as causing another person's death with intent to kill and recognizes ordinary common-law causation principles. The prosecutor is considering a murder charge. Which of the following is the strongest conclusion regarding causation?

                • A. The driver did not cause the death because the pedestrian knowingly refused treatment that probably would have prevented it.
                • B. The driver caused the death because the refusal of treatment was not an unforeseeable intervening cause that superseded the intentional injuries.
                • C. The driver did not cause the death because the physicians could have prevented it by performing surgery despite the refusal.
                • D. The driver caused the death only if the prosecution proves that the driver knew the pedestrian would refuse surgery.
                Show answer

                Answer: B. The driver caused the death because the refusal of treatment was not an unforeseeable intervening cause that superseded the intentional injuries.

                The driver caused the death because the refusal of treatment was not an unforeseeable intervening cause that superseded the intentional injuries. - The intentional collision caused the severe internal injuries from which the pedestrian died, satisfying actual causation. - Refusing surgery because of a sincere fear of anesthesia did not supersede those injuries, which remained the operative cause of death. The driver did not cause the death because the pedestrian knowingly refused treatment that probably would have prevented it. - The surgery’s 90% chance of survival does not mean the pedestrian’s refusal erased the driver’s causal role. - A victim generally need not accept medical treatment to preserve causation for injuries inflicted by another person. The driver did not cause the death because the physicians could have prevented it by performing surgery despite the refusal. - The physicians provided appropriate nonsurgical care after the pedestrian refused surgery. - They were not required to perform surgery without consent, so their conduct did not break the causal chain. The driver caused the death only if the prosecution proves that the driver knew the pedestrian would refuse surgery. - Proximate causation does not require the driver to foresee the pedestrian’s particular fear of anesthesia. - The question asks whether the refusal superseded the intentional injuries, not whether the driver predicted that decision.

              • 9. A warehouse employee agreed with a friend to steal computer processors from the warehouse. The employee gave the friend a security code and promised to leave a loading door unlocked at midnight. Before midnight, the employee became frightened, telephoned the friend, and said, "I am out. Do not go through with this." The employee then changed the security code and locked the loading door but did not notify police. The friend nevertheless entered through an unlocked window and stole the processors. The jurisdiction follows the common-law rules of conspiracy and accomplice liability. The employee is charged with conspiracy and with the completed theft as an accomplice. Which of the following is the strongest conclusion?

                • A. The employee is not guilty of either offense because changing the code and locking the door constituted complete withdrawal.
                • B. The employee is guilty only of theft because withdrawal erased the conspiracy but did not neutralize the prior assistance.
                • C. The employee is guilty of both offenses because withdrawal cannot affect liability for either conspiracy or the completed crime.
                • D. The employee remains guilty of conspiracy but likely avoided accomplice liability by timely communicating withdrawal and neutralizing the assistance.
                Show answer

                Answer: D. The employee remains guilty of conspiracy but likely avoided accomplice liability by timely communicating withdrawal and neutralizing the assistance.

                The employee remains guilty of conspiracy but likely avoided accomplice liability by timely communicating withdrawal and neutralizing the assistance. - Under common-law rules, the conspiracy was complete upon agreement to steal the processors, so later withdrawal does not erase it. - Before the theft, the employee told the friend not to proceed, changed the code, and locked the door, likely neutralizing the prior assistance even though the friend entered through a window. The employee is not guilty of either offense because changing the code and locking the door constituted complete withdrawal. - Changing the code and locking the door cannot undo the completed conspiracy. - Those actions, together with the call to the friend, matter instead to liability as an accomplice to the later theft. The employee is guilty only of theft because withdrawal erased the conspiracy but did not neutralize the prior assistance. - Withdrawal does not erase the agreement that established common-law conspiracy. - The employee acted before the theft to revoke the offered access and secure both the code and loading door, making continued accomplice liability unlikely. The employee is guilty of both offenses because withdrawal cannot affect liability for either conspiracy or the completed crime. - The agreement remains punishable as conspiracy despite the employee’s later change of mind. - Unlike conspiracy liability, accomplice liability for the later theft can be avoided by timely withdrawal and neutralization of prior assistance.

              Flashcards: Other constitutional protections

              1. 1. What must a defendant prove to establish ineffective assistance of counsel?

                Show answer

                Under Strickland, the defendant must show that counsel’s performance fell below an objective standard of reasonableness and that the deficiency prejudiced the defense. Prejudice requires a reasonable probability that, without the error, the result would have been different.

              2. 2. What constitutional standard determines whether a confession is involuntary?

                Show answer

                Under the Due Process Clause, a confession is involuntary if police coercion overcame the suspect’s will, judged under the totality of the circumstances. Coercive police conduct is required; the suspect’s personal vulnerabilities alone are insufficient.

              3. 3. What are the principal Eighth Amendment protections relevant to a criminal defendant?

                Show answer

                Bail may not be excessive in relation to the government’s legitimate interests, and punishment may not be cruel and unusual or grossly disproportionate under the applicable proportionality rules. The Eighth Amendment also prohibits excessive fines.

              4. 4. What does the Fifth Amendment privilege against self-incrimination protect, and what may the government still compel?

                Show answer

                It protects a person from being compelled to provide testimonial, incriminating communication, but it does not protect non-testimonial physical evidence such as fingerprints, handwriting samples, or DNA. The privilege applies in criminal proceedings and to compelled testimony that could reasonably be used in a criminal prosecution.

              5. 5. When does the Sixth Amendment Confrontation Clause bar prosecution use of an out-of-court statement?

                Show answer

                Under the majority rule, the Clause bars a testimonial statement by an unavailable witness unless the defendant had a prior opportunity to cross-examine the witness, subject to forfeiture by wrongdoing. It generally does not bar nontestimonial statements.

              6. 6. What is required for a valid Miranda waiver after custodial interrogation begins?

                Show answer

                Before custodial interrogation, police must advise the suspect of the rights to remain silent and to counsel, and the suspect must knowingly, intelligently, and voluntarily waive those rights. A statement obtained after an unambiguous invocation of counsel generally may not be used in the prosecution’s case-in-chief unless counsel is present.

              7. 7. When does the Sixth Amendment right to counsel attach, and what proceedings are covered?

                Show answer

                The right attaches when adversarial judicial proceedings begin, such as formal charge, indictment, arraignment, or first appearance, and applies at critical stages where substantial rights may be affected. It is offense-specific, so police may question a represented defendant about an unrelated offense unless another protection applies.

              8. 8. When does double jeopardy attach, and what does it generally prohibit?

                Show answer

                Double jeopardy attaches when the jury is sworn, or in a bench trial when the first witness is sworn. It generally bars a second prosecution for the same offense after acquittal or conviction, subject to exceptions such as a mistrial for manifest necessity and the separate-sovereigns rule.

              9. 9. What factors govern a defendant’s Sixth Amendment speedy-trial claim?

                Show answer

                Under Barker v. Wingo, courts balance the length of the delay, the reason for the delay, the defendant’s assertion of the right, and prejudice to the defense. A violation generally requires dismissal of the charges, not merely suppression of evidence.

              10. 10. What test determines whether two offenses are the “same offense” for double-jeopardy purposes?

                Show answer

                Under the majority Blockburger test, offenses are different only if each requires proof of a fact the other does not; a lesser-included offense is the same offense as the greater offense. The prosecution generally may not impose cumulative punishment for the same offense unless the legislature clearly authorizes it.
