(a) In deciding any case subject to this article, before granting any relief the ordering authority shall make a written finding either:

(1) That there are no victims to whom restitution should be made under the policy of this state;

(2) That the circumstances of the case are such that no restitution order or plan is reasonably possible;

(3) That the offender, in cooperation with the ordering authority, has developed and consented to a plan of restitution, which plan shall be made a part of a restitution order; or

(4) That restitution will be ordered as a condition of the relief.

(b) The failure to make a finding as required by this Code section, however, shall not invalidate any order or other action of the ordering authority.
