compel discovery or order such party to permit the
discovery or inspection, grant continuance, or

disclosed, or it may enter such other order as it

(2) the party could not have disclosed the
information earlier with due diligence and the
party disclosed the information immediately upon
its discovery.
c. In considering an appropriate sanction for
nondisclosure or untimely disclosure, a court shall
determine the significance of the information not
timely disclosed, the impact of the violation on the
overall administration of the case, the impact of the
sanction on the party and the victim, and the stage of
the proceedings when the party ultimately made the

work product of either attorney which is deemed to include legal

memoranda which are only the opinions, theories, or conclusions of
