Giglio Information: A Comprehensive Guide to Its Legal Definition

Definition & Meaning

Giglio information refers to material that can challenge the credibility of a prosecution witness in a criminal trial. This includes any evidence that could undermine the witness's character or testimony. The obligation to disclose such information stems from the Supreme Court's rulings, particularly in Giglio v. United States, which established that the prosecution must reveal any information that could be used to impeach the credibility of its witnesses, including law enforcement officers.
