Google Scholar. State v. Laurie, 139 N.H. 325 (1995)"In Brady v. Maryland, 373 U.S. 83, 87 (1963), the United States Supreme Court held that "suppression by the prosecution of evidence favorable to an accused upon request violates due process where the evidence is material either to guilt or to punishment, irrespective of the good faith or bad faith of the prosecution." This rule applies where no request for information was made and where a general request for exculpatory information was made. The rule also applies to impeachment materials. ... In New Hampshire, criminal defendants have an explicit right "to produce all proofs that may be favorable to [them]." N.H. CONST. pt. I, art. 15. … We hold that the New Hampshire constitutional right to present all favorable proofs affords greater protection [than the federal standard] to a criminal defendant. Upon a showing by the defendant that favorable, exculpatory evidence has been knowingly withheld by the prosecution, the burden shifts to the State to prove beyond a reasonable doubt that the undisclosed evidence would not have affected the verdict. This standard does not require that the prosecutor disclose everything that might influence a jury, or that the defendant be permitted a complete discovery of all investigatory work or an examination of the State's complete file."
