Title 42, Chapter 9, Section 40
(a) The board shall adopt, implement, and maintain a parole
guidelines system for determining parole action. The guidelines
system shall be used in determining parole actions on all inmates,
except those serving life sentences, who will become statutorily
eligible for parole consideration. The system shall be consistent
with the board's primary goal of protecting society and shall take
into consideration the severity of the current offense, the inmate's
prior criminal history, the inmate's conduct, and the social factors
which the board has found to have value in predicting the
probability of further criminal behavior and successful adjustment
under parole supervision.
(b) The guidelines system required by subsection (a) of this Code
section shall be adopted by rules or regulations of the board. The
rules or regulations shall be adopted in conformity with Chapter 13
of Title 50, the "Georgia Administrative Procedure Act."
