The State of North Carolina (through the prosecutors) is required to turn over certain types of evidence to the accused (the Defendant in NC). Criminal lawyers in Charlotte, and other attorneys throughout the state, often refer to that as Giglio or exculpatory Brady material.
Both Brady and Giglio, and the associated release of documentation, are related to one another, at least in part. Neither is strictly what may you think of as a Motion for Discovery or N.C.G.S. 15A-903, the NC discovery law.
It’s more than that. Prosecutors have enhanced duties to provide certain materials pursuant to ethical responsibilities and constitutional precepts.
