A sex offender’s conviction and 30-year prison sentence was overturned Monday by the Georgia Supreme Court, officials say.

Prentiss Ashon Jackson of Macon was convicted in 2012 of failing to register as a convicted sex offender when he moved in with his girlfriend, the Macon Telegraph reported.

Jackson had registered his Warner Robins address as required after pleading guilty to statutory rape in 2004. But when he couldn’t be found at that address in 2011, police arrested him in 2012, the newspaper reported.

In Monday’s unanimous Supreme Court opinion, the high court ruled that the indictment used to convict Jackson of failure to register was defective because it failed to inform him of the “essential elements” of the crime for which he was charged.
