MINNEAPOLIS — Nine residents have filed a class action lawsuit in southern Minnesota, demanding 36 cities and counties return at least $2 million raised through driver diversion classes.

The programs give motorists the option of enrolling in a safe-driving class instead of paying a ticket for a violation.

The group’s attorney Erick Kaardal said the public doesn’t understand how the state auditor, attorney general and the courts can tell law enforcement officials the diversion programs are illegal. But the programs continue to be offered, typically by police and sheriff’s departments.
