(a) Where a sentence of imprisonment has been imposed on a convicted offender, the Court of Indian Offenses may, in its discretion, suspend the serving of such sentence and release the person on probation under any reasonable conditions deemed appropriate by the court, provided that the period of probation shall not exceed one year.

(b) Any person who violates the terms of his or her probation may be required by the court to serve the sentence originally imposed or such part of it as the court may determine to be suitable giving consideration to all the circumstances, provided that such revocation of probation shall not be ordered without a hearing before the court at which the offender shall have the opportunity to explain his or her actions.
