The answer will probably depend on how many days a month the probation cases are heard by the judge. Here in NJ, the VOP days are set once a month. Have his lawyer check with the court that put him on probation and they should be able to tell the lawyer the date. Good luck.

That last answer will be unhelpful to you. The reality is that a person in Wisconsin can be held for months on a probation hold. If this person is being revoked, he will be held in jail until the hearing. There is essentially no enforceable time limit in which the hearing must be held. Typically, when a person is being held while the probation department is investigating allegations, a decision as to whether or not to revoke will be made within a matter of days. At the six day point, I would suspect the department of corrections has at least taken a statement from your friend. The better approach is to contact the probation agent to see what he or she is thinking about this matter. If you call that person though, be careful not to talk about the details of the violations if you have any inside knowledge into what occured. I do a considerable amount of probation revocation work, so if you would like to call I would be happy to answer any questions.
