Which case requires the disclosure of exculpatory evidence?

• A. Giglio
• B. Jencks Act
• C. Rule 16
• D. Brady v. Maryland

Answer: (D)

Brady v. Maryland is about ensuring fairness by requiring the prosecution to turn over exculpatory evidence to the defense. Exculpatory evidence is information that could help the defendant by negating guilt or undermining the prosecution’s case. Brady holds that suppressing such evidence violates due process, and the evidence must be disclosed if it is material to the outcome of the case. In other words, if the evidence could reasonably be expected to influence the verdict, it has to be shared. The other items address related but distinct duties. The Jencks Act deals with producing prior statements of witnesses after they testify, mainly for impeachment purposes. Giglio v. United States extends Brady to impeachment materials specific to a witness’s credibility, such as deals or promises affecting reliability. Rule 16 covers general discovery rights for the defense but isn’t solely about exculpatory evidence. So the case that establishes the mandatory disclosure of exculpatory evidence itself is Brady v. Maryland.
