Yes, if an inmate has court fees, a fine or restitution, the institution will deduct an amount that they deem appropriate (some arbitrary percentage) from the inmate's books. If they stopped deducting money, maybe it's paid back or maybe he has nothing in there. If he has money on his books and he still owes money, they haven't "stopped".
