[keyelement]

Was sentenced to 66 months state penn with 180 months post prison supervision. I served my time earned my GED was a good prisoner. Earned one year off for good behavior as i was not measure 11. Now upon getting near to the end of my post prison supervision i am told I must do an extra year on post prison supervision it is like they are not honoring my year off for good behavior and making me do it on PPS. Is this legal and if not what can I do about it I get no help from myPO if anything she makes it worse.

I wish to inform you that it is the Order passed in the judgment that will have jurisdiction in this matter. You may inform the authorities that you have been awarded one year off for good behavior. If the matter is not resolved satisfactorily, you may file a Motion in the same Court which awarded you the punishment with a request to determine the status of the one year off awarded for good behavior and the time period of the post prison supervision.
