Aranzi Rae Jon Willis v. Hon. bernini/state

Summary

The court held that the Arizona Constitution guarantees a person under grand-jury investigation a due-process right to a fair and impartial presentation of evidence. Prosecutors must present clearly exculpatory evidence without a specific request, including evidence relevant to a justification defense when it would deter a probable-cause finding. Because the State omitted evidence bearing on whether the alleged shooter acted in self-defense and thereby impeded the grand jury's inquiry, the court vacated the denial of Willis's motion and remanded for a new probable-cause determination.
