"Michigan’s Supreme Court ruled Tuesday that the indictment of former Gov. Rick Snyder (R) and several other officials in connection with the contamination of water in Flint was improper because the grand jury consisted of a single judge.
The high court unanimously overturned the indictments against Snyder and eight others, including former health director Nick Lyon. The one-judge Genesee County grand jury overstepped its legal authority by issuing the indictments, the court wrote.
While state statutes “authorize the use of a one-man grand jury to investigate, subpoena witnesses, and issue arrest warrants, those statutes do not authorize that one-man grand jury to issue an indictment initiating a criminal prosecution,” the court wrote in a 6-0 decision."
