Since he is no longer on probation, the probation officer has no legal authority over him. He is not required to speak with the probation officer at all. If the probation officer continues to harass your husband, family or friends then you should complain to the probation officer's supervisor.
This sounds odd to me. You may want to talk to the PO or his/her supervisor and ask for what legitimate purpose the PO is talking w/your husband. Also, YOU need to consult with an experienced Criminal Defense/DWI atty. from your area ASAP.
