Legal Question in Criminal Law in Michigan

Yes, a prosecutor is able to vacate (or withdraw) his or her agreement after the plea and even after sentencing. This is a post-trial motion that takes places in specific circumstances. The most common types of circumstances involving this type of motion is usually due to the defendant not full-filling or unable to full-fill his or her duty as stated within the plea agreement. Of course, with the little facts you have provided this is where my advice and comments begin to dwindle. You should speak with your attorney if you not understand what is going on or have general questions.

Good luck.
