Joseph Haywood Campbell v. State of Minnesota

Summary

The court affirmed the denial of Campbell's postconviction petition without an evidentiary hearing. It held that Campbell's alleged witness recantation lacked sufficient trustworthy evidence, his ineffective-assistance claim was procedurally barred because it could have been raised on direct appeal, and the alleged undisclosed benefit to a prosecution witness was not material under the Brady standard. The court also declined to consider Campbell's inadequately briefed claim that the prosecutor failed to correct false testimony.
