My question involves juvenile criminal law for the state of Michigan:

I am trying to understand Michigan's laws regarding minors on probation, probation violations and being arrested. Recenty, a 19 year old female who had a previous MIP of alcohol, was found consuming alcohol and arrested at the scene. She was brought to Ottawa county jail and was held overnight. After posting bail and discussing the situation with her parole office and lawyer it was discovered the parole officer was never contacted and was able to avoid the second MIP charge and just had her probation extended. Now, my question is in Michigan’s laws is it a violation on the arresting officer’s part to not notify the parole officer of the arrest and this is why she avoided the chargers, or would it be the lawyer who was able to get the MIP offense removed and talked down to an extension of her probation?
