Full(er) Disclosure: Wisconsin Invigorates the Brady Rule
A Warren Court cornerstone has been “remastered and upgraded,” as they say, by the Wisconsin Supreme Court in a case that has riled the waters nationally. In Brady v. Maryland (1963), the Warren Court held that prosecutors must disclose exculpatory evidence to the defense. No hiding the ball. Over fifty years of case law, however, has occluded the rule with sundry conditions and qualifications that obscure its modest disclosure provision. More time is spent describing the ball than looking for it.
In State v. Wayerski (2019 WI 11), the Wisconsin Supreme Court scraped off Brady’s barnacles, overruled fifty years of precedent, and held that prosecutors must provide the defense with any information that is exculpatory or impeaching — even if the defense could have found it as easily as the prosecutor.
