Task: Exculpatory Evidence

Giglio v. United States, 405 U.S. 150 (1972).

•When evidence, bearing on the credibility of a witness, is withheld from

the defendant, irrespective of the good or bad faith of the prosecution,
then there may be a violation of Due Process, requiring the granting of

a new trial, if the undisclosed exculpatory evidence has “any
reasonable likelihood of [having] affected the judgment of the jury.

•It is this case that requires law enforcement agencies to notify

prosecutors of any dishonesty in an officer’s background before the

officer testifies in a criminal case.

•NOTE: The requirement for law enforcement is to turn the

information/evidence over to the prosecutor.
