What does motion withdrawn d/mtn for mandatory release mean

Have your friend or his family call the clerk's office to be sure, but it sounds like the State did not file charges based upon the info you provided. So, yes, that would be a good thing if it is what occurred.

Yes, it means that the state declined to file criminal charges and your friend should be released. The Mtn for mandatory relief was filed when the state took took too long to file an information or no-file it. Once it no-filed the case, the motion was moot and withdrawn. Your friend is coming home.

It would seem the chare was not filed on

I agree with my colleagues. The only reason your friend would not be released at this point is if he was being held on another charge or a violation of probation.
