(a) The governor, after consultation with the board and
the department, shall adopt rules and regulations to establish a
system of good time and special good time allowances for inmates
of and parolees from any state penal institution, any
institution which houses Wyoming inmates pursuant to W.S.
7-3-401 or any correctional facility operated pursuant to a
contract with the state under W.S. 7-22-102 or inmates or
parolees transferred to a community correctional facility
pursuant to W.S. 7-18-109 or 7-18-115. The rules may provide
either for good time to be deducted from the maximum sentence or
for good time to be deducted from the minimum sentence imposed
by the sentencing court, or both, and may provide for the
removal of previously earned good time allowances and the
withholding of future good time allowances.

     (b) The rules and regulations adopted by the governor as
provided by this section shall be filed in the office of the
secretary of state but shall at all times be considered rules
relating to the internal management of state penal institutions
and not affecting private rights of inmates. The granting,
refusal to grant, withholding or restoration of good time or
special good time allowances to inmates shall be a matter of
grace and not that of right of inmates.

     (c) The court may adjust the period of a probationer’s
supervised probation on the recommendation of the probation and
parole agent, which shall be based on the probationer's positive
progression towards the goals of the case plan as well as the
overall compliance with the conditions imposed by the court.

     (d) The rules established under subsection (a) of this
section shall:

          (i) Provide that good time may be awarded for time
the sentencing court awards as jail credit in the judgment and
sentence if the inmate or parolee would have otherwise received
good time credit if the inmate or parolee had served that time
in an institution eligible under subsection (a) of this section;

          (ii) Provide that good time may be awarded for any
time an inmate or parolee spends in custody from the date of
sentencing until admission to an institution eligible under
subsection (a) of this section;

          (iii) Require the department to consult with the
county sheriff to determine whether good time should be awarded
to an inmate or parolee before awarding good time for jail
credit under this subsection.
