City prosecutors in Lansing recently dropped 50 misdemeanor cases after the city council accidentally let hundreds of ordinances expire last year.
The Lansing State Journal reports that as a result, the defendants in those cases won't be prosecuted at any level.
According to city officials, the alleged crimes were non-violent. The most common charges were trespassing and providing false information to a police officer.
In February, officials discovered the city council had missed a 10-year deadline to renew at least 100 local laws.
