LANSING, Mich. (Michigan News Source) – The Michigan Supreme Court has rejected a last-chance effort to revive criminal charges against seven people allegedly connected to the Flint water scandal.

The state’s highest court said on Wednesday, “We are not persuaded that the question presented should be reviewed by this court.” The one sentence order quashed further appeals by Attorney General Dana Nessel’s office, which has  fought tooth-and-nail to get around a 2022 decision that gutted the cases.

Nessel’s office attempted to use a one-judge grand jury in order to return indictments. However, the Michigan Supreme Court cited that process as unconstitutional in a ruling last year, and it struck down those charges.

Instead of taking the loss and moving on, state prosecutors returned to Flint courts and argued the charges could be easily revived with a simple refiling of documents. Lower courts repeatedly rejected that position until it arrived at the Michigan Supreme Court again, where it received its final strike.

Orders were filed in cases against former state health director Nick Lyon, former state medical executive Eden Wells and five other people.

Former Michigan Gov. Rick Snyder faced a willful neglect of duty charge, which is a misdemeanor. The indictment against him has been dismissed as well.

Managers appointed by Snyder turned the Flint River into a source for Flint city water in 2014, but the water wasn’t treated to reduce corrosion in old pipes. That move caused lead to leach into the system for 18 months.

Lyon and Wells were charged with involuntary manslaughter. Some experts have attributed a fatal Legionnaires’ disease outbreak in 2014-15 to the water switch. They were accused of not timely warning the public.

Indictments were also thrown out against Snyder’s former chief of staff, Jarrod Agen; aide, Rich Baird; former Flint Managers Gerald Ambrose and Darnell Earley; former city Public Works Director Howard Croft; and former health official Nancy Peeler.

Snyder’s lawyers said his conduct did not warrant a crime, and Snyder himself acknowledged Michigan’s state government botched the water switch.
