(a) Motion to submit supplemental information. Once a trial has been instituted, a party may file a motion to submit supplemental information in accordance with the following requirements:

(1) A request for the authorization to file a motion to submit supplemental information is made within one month of the date the trial is instituted.

(2) The supplemental information must be relevant to a claim for which the trial has been instituted.

(b) Late submission of supplemental information. A party seeking to submit supplemental information more than one month after the date the trial is instituted, must request authorization to file a motion to submit the information. The motion to submit supplemental information must show why the supplemental information reasonably could not have been obtained earlier, and that consideration of the supplemental information would be in the interests-of-justice.

(c) Other supplemental information. A party seeking to submit supplemental information not relevant to a claim for which the trial has been instituted must request authorization to file a motion to submit the information. The motion must show why the supplemental information reasonably could not have been obtained earlier, and that consideration of the supplemental information would be in the interests-of-justice.
