I think that you are confused.
Your case is closed. You pled guilty (or no contest) and are on felony probation. There is no requesting a misdemeanor conviction. If you were not guilty then you should not have entered a plea and should have gone to trial. There are no “do overs”.
I would very strongly suggest that if you are asking a Judge to exercise her / his discretion in granting you early termination (“ET” – (which is what you are doing – asking, and the Judge is under no obligation whatsoever to oblige you) that you not mention anything about police misconduct or try to minimize or redirect blame…. again, you pled guilty (or no contest) and proclaiming innocence would be counterproductive to your immediate objective.
Insofar as ET is concerned, once again, the issues of probation enforcement, modification, ET and transfer are all 100% discretionary with the Court – that is to say that the Judge is free to say either yes or no without fear of appellate action… it is entirely the Judge’s call. Good mood, bad mood, bias, prejudice, sleep, lack of sleep, etc… all of these intangibles can effect the Judge’s attitude and ultimate decision.
Still, if there is an unwritten rule then it s this: ET / conversion will generally NOT be granted until at least 50% of the CC / probationary term has been successfully (without any allegations of violation) served AND all conditions having been completely satisfied. Again, this is not set in stone, but it is a generally reliable guideline.
Thus, the best way for you to hedge your bet and to accomplish your objective is for you to hire yourself a dialed-in criminal defense lawyer who can stitch together a comprehensive and persuasive packet of materials geared toward skewing the ruling in your favor. As with most things in criminal court, your odds are likely to exponentially increase with a skilled and experienced criminal defense lawyer at the helm.
I hope that I have been helpful in answering your question.
