My question involves criminal law for the state of: Georgia
My brother was given a 10 years serve six year sentence in county A,
He was also given a 10 years to serve in county B,
County A would not start his remaining 4 years on his county A sentence until he was released from his County B sentence. Both sentences were concurrent
also under OCGA 17-1-1(4)
4) In cases of imprisonment followed by probation, the sentence shall specifically provide that the period of probation shall not begin until the defendant has completed service of the confinement portion of the sentence. No revocation of any part of a probated sentence shall be effective while a defendant is in the legal custody of the State Board of Pardons and Paroles.
He thought that when his 10 year sentence(County B) was over that it overode his County B sentence since it was longer? He is disabled and now they want to revoke the remaning 4 years and it doesn't seem fair.
