People of Michigan v. Joshun Edwards

Summary

The court held that the prosecution violated the defendants’ constitutional disclosure rights by withholding the complete transcript of its first interview with the principal witness. The transcript was material because it supplied substantial impeachment evidence, undermined the prosecution’s other evidence and theory, and raised questions about the investigation’s thoroughness and good faith. The defendants established good cause and actual prejudice under the post-conviction-relief rule and were entitled to new trials.
